We have developed a robust B-cell directed research and development (R&amp;D) platform for identification of key B-cell pathways of interest and rapid clinical testing. Currently, we have five B-cell targeted drug candidates in clinical development, with the lead two therapies, ublituximab (TG-1101) and umbralisib (TGR-1202), in pivotal trials for CLL, NHL and MS. Ublituximab is a novel anti-CD20 monoclonal antibody (mAb) that has been glycoengineered for enhanced potency over first generation antibodies. Umbralisib is an oral, once daily, dual inhibitor of PI3K-delta and CK1-epsilon, which may lead to a differentiated safety profile. When used together in combination therapy, ublituximab and umbralisib are referred to as "U2". Additionally, in early clinical development we have an anti-PD-L1 monoclonal antibody referred to as cosibelimab (TG-1501), an oral Bruton’s Tyrosine Kinase (“BTK”) inhibitor referred to as TG-1701, and an anti-CD47/CD19 bispecific antibody referred to as TG-1801.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;margin:0pt;">  </p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">We also actively evaluate complementary products, technologies and companies for in-licensing, partnership, acquisition and/or investment opportunities. To date, we have not received approval for the sale of any of our drug candidates in any market and, therefore, have not generated any product sales from our drug candidates.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">​</span></p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">LIQUIDITY AND CAPITAL RESOURCES</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We have incurred operating losses since our inception, and expect to continue to incur operating losses for the foreseeable future and may never become profitable. As of December 31, 2019, we have an accumulated deficit of $701.2 million.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Our major sources of cash have been proceeds from the private placement and public offering of equity securities, and in 2019 from our loan and security agreement executed with Hercules Capital, Inc. (“Hercules”) (See Note 7 for more information). We have not yet commercialized any of our drug candidates and cannot be sure if we will ever be able to do so. Even if we commercialize one or more of our drug candidates, we may not become profitable. Our ability to achieve profitability depends on many factors, including our ability to obtain regulatory approval for our drug candidates; successfully complete any post-approval regulatory obligations; and successfully commercialize our drug candidates alone or in partnership. We may continue to incur substantial operating losses even if we begin to generate revenues from our drug candidates.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">As of December 31, 2019, we had $140.4 million in cash and cash equivalents, and investment securities. We anticipate that our cash and cash equivalents, and investment securities as of December 31, 2019 will provide sufficient liquidity for more than a twelve-month period from the date of filing this Annual Report on Form 10-K. The actual amount of cash that we will need to operate is subject to many factors, including, but not limited to, the timing, design and conduct of clinical trials for our drug candidates. We are dependent upon significant future financing to provide the cash necessary to execute our current operations, including the commercialization of any of our drug candidates.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Our common stock is quoted on the Nasdaq Capital Market and trades under the symbol “TGTX.”</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-weight:bold;visibility:hidden;">​</span></p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:0pt;margin:0pt 0pt 12pt 0pt;"><b style="font-weight:bold;">RECENTLY ISSUED ACCOUNTING STANDARDS</b></p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In July 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2018-11, “Leases - Targeted Improvements” (“ASU 2018-11”) as an update to ASU 2016-02, Leases (“ASU 2016-02” or “Topic 842”) issued on February 25, 2016. ASU 2016-02 is effective for public business entities for fiscal years beginning January 1, 2019. ASU 2016-02 required companies to adopt the new leases standard at the beginning of the earliest period presented in the financial statements, which is January 1, 2017, using a modified retrospective transition method where lessees must recognize lease assets and liabilities for all leases even though those leases may have expired before the effective date of January 1, 2017. Lessees must also provide the new and enhanced disclosures for each period presented, including the comparative periods.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">ASU 2018-11 provides an entity with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new lease standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new lease standard will continue to be in accordance with ASC 840, Leases (“ASC 840”). An entity that elects this additional (and optional) transition method must provide the required ASC 840 disclosures for all periods that continue to be in accordance with ASC 840. The amendments do not change the existing disclosure requirements in ASC 840.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">ASU 2018-11 is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with earlier adoption permitted. The Company adopted ASU 2018-11 on January 1, 2019 using a modified retrospective method and will not restate comparative periods. We elected the package of practical expedients permitted under the transition guidance, which allows us to carryforward our historical lease classification and our assessment on whether a contract is or contains a lease. The adoption of this guidance resulted in the addition of material balances of right of use assets and lease liabilities to our consolidated balance sheets at January 1, 2019, primarily relating to our lease of office space (see Note 8). The impact to our consolidated statements of operations was not material as a result of this standard.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In June 2018, the FASB issued ASU No. 2018-07, “Improvements to Nonemployee Share-Based Payment Accounting” (“ASU 2018-07”). ASU 2018-07 expands the scope of FASB Topic 718, Compensation – Stock Compensation (“Topic 718”) to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should only remeasure equity-classified awards for which a measurement date has not been established through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Upon transition, the entity is required to measure these nonemployee awards at fair value as of the adoption date. The entity must not remeasure assets that are completed. Disclosures required at transition include the nature of and reason for the change in accounting principle and, if applicable, quantitative information about the cumulative effect of the change on retained earnings or other components of equity.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">ASU 2018-07 is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company adopted ASU 2018-07 on January 1, 2019. The adoption of ASU 2018-07 did not have a material effect on our consolidated financial statements as of January 1, 2019. The adoption of ASU 2018-07 had no impact on nonemployee performance awards as they are measured based on the outcome that is probable.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Other pronouncements issued by the FASB or other authoritative accounting standards with future effective dates are either not applicable or not significant to our condensed consolidated financial statements.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">USE OF ESTIMATES</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the applicable reporting period. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses and stock-based compensation. Actual results could differ from those estimates. Such differences could be material to the financial statements.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">CASH AND CASH EQUIVALENTS</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We treat liquid investments with original maturities of less than three months when purchased as cash and cash equivalents.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">RESTRICTED CASH</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We record cash pledged or held in trust as restricted cash. As of December 31, 2019 and 2018, we have approximately $1.3 million of restricted cash pledged to secure a line of credit as a security deposit for an Office Agreement (see Note 8).</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">INVESTMENT SECURITIES</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Investment securities at both December 31, 2019 and 2018 consist of short-term government securities. We classify these securities as held-to-maturity. Held-to-maturity securities are those securities in which we have the ability and intent to hold the security until maturity. Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Premiums and discounts are amortized or accreted over the life of the related held-to-maturity security as an adjustment to yield using the effective interest method.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">A decline in the market value of any investment security below cost, that is deemed to be other than temporary, results in a reduction in the carrying amount to fair value. The impairment is charged to operations and a new cost basis for the security is established. Other-than-temporary impairment charges are included in interest and other income (expense), net. Dividend and interest income are recognized when earned.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">CREDIT RISK</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and short-term investments. The Company maintains its cash and cash equivalents and short-term investments with high-credit quality financial institutions. At times, such amounts may exceed federally-insured limits.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">REVENUE RECOGNITION</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Effective January 1, 2018, the Company began recognizing revenue under ASC Topic 606, <i style="font-style:italic;">Revenue from Contracts with Customers</i> (“ASC 606”), using the modified retrospective transition method. The impact of adopting the new revenue standard was not material to our consolidated financial statements and there was no adjustment to beginning retained earnings on January 1, 2018. The core principle of this new revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle:</p><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 1: Identify the contract with the customer</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 2: Identify the performance obligations in the contract</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 3: Determine the transaction price</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 4: Allocate the transaction price to the performance obligations in the contract</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 5: Recognize revenue when the company satisfies a performance obligation</span></td></tr></table><div style="margin-top:12pt;"/><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised good or service that is distinct. A performance obligation meets ASC 606’s definition of a “distinct” good or service (or bundle of goods or services) if both of the following criteria are met:</p><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">The customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct).</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">The entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to transfer the good or service is distinct within the context of the contract).</span></td></tr></table><div style="margin-top:12pt;"/><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties (for example, some sales taxes). The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The transaction price is allocated to each performance obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized when that performance obligation is satisfied, at a point in time or over time as appropriate.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">RESEARCH AND DEVELOPMENT COSTS</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Generally, research and development costs are expensed as incurred. Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are deferred and amortized over the period that the goods are delivered or the related services are performed, subject to an assessment of recoverability. We make estimates of costs incurred in relation to external clinical research organizations, or CROs, and clinical site costs. We analyze the progress of clinical trials, including levels of patient enrollment, invoices received and contracted costs when evaluating the adequacy of the amount expensed and the related prepaid asset and accrued liability. Significant judgments and estimates must be made and used in determining the accrued balance and expense in any accounting period. We review and accrue CRO expenses and clinical trial study expenses based on work performed and rely upon estimates of those costs applicable to the stage of completion of a study. Accrued CRO costs are subject to revisions as such trials progress to completion. Revisions are charged to expense in the period in which the facts that give rise to the revision become known. With respect to clinical site costs, the financial terms of these agreements are subject to negotiation and vary from contract to contract. Payments under these contracts may be uneven, and depend on factors such as the achievement of certain events, the successful recruitment of patients, the completion of portions of the clinical trial or similar conditions. The objective of our policy is to match the recording of expenses in our financial statements to the actual services received and efforts expended. As such, expense accruals related to clinical site costs are recognized based on our estimate of the degree of completion of the event or events specified in the specific clinical study or trial contract.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Prepaid research and development in our consolidated balance sheets includes, among other things, costs related to agreements with CRO’s, certain costs to third party service providers related to development and manufacturing services as well as clinical development. These agreements often require payments in advance of services performed or goods received. Accordingly, as of December 31, 2019 and December 31, 2018, we recorded approximately $8.1 million and $9.7 million, respectively, in prepaid research and development related to such advance agreements.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">INCOME TAXES</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. If the likelihood of realizing the deferred tax assets or liability is less than “more likely than not,” a valuation allowance is then created.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We, and our subsidiaries, file income tax returns in the U.S. Federal jurisdiction and in various states. We have tax net operating loss carryforwards that are subject to examination for a number of years beyond the year in which they were generated for tax purposes. Since a portion of these net operating loss carryforwards may be utilized in the future, many of these net operating loss carryforwards will remain subject to examination. We recognize interest and penalties related to uncertain income tax positions in income tax expense. Refer to Note 9 for further information on impact of tax reform.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">STOCK-BASED COMPENSATION</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We recognize all stock-based payments to employees and non-employee directors (as compensation for service) as noncash compensation expense in the consolidated financial statements based on the fair values of such payments. Stock-based compensation expense recognized each period is based on the value of the portion of stock-based payment awards that is ultimately expected to vest during the period. Forfeitures are recognized as they occur.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In addition, because some of the options, restricted stock and warrants issued to employees, consultants and other third parties vest upon achievement of certain milestones, the total expense is uncertain. Compensation expense for such awards that vest upon the achievement of milestones is recognized when the achievement of such milestones becomes probable.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">BASIC AND DILUTED NET LOSS PER COMMON SHARE</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Basic net loss per share of our common stock is calculated by dividing net loss applicable to the common stock by the weighted-average number of our common stock outstanding for the period. Diluted net loss per share of common stock is the same as basic net loss per share of common stock since potentially dilutive securities from stock options, stock warrants and convertible preferred stock would have an antidilutive effect either because we incurred a net loss during the period presented or because such potentially dilutive securities were out of the money and the Company realized net income during the period presented. The amounts of potentially dilutive securities excluded from the calculation were 8,361,739, 6,528,932 and 4,835,706 at December 31, 2019, 2018 and 2017, respectively. During the years ended December 31, 2019, 2018 and 2017, the Company incurred a net loss, therefore, all of the securities are antidilutive and excluded from the computation of diluted loss per share.</p><table style="border-collapse:collapse;font-size:16pt;margin-left:auto;margin-right:auto;padding-left:0pt;padding-right:0pt;width:100%;"><tr style="height:1pt;"><td

style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Long-lived assets are reviewed for potential impairment when circumstances indicate that the carrying value of long-lived tangible and intangible assets with finite lives may not be recoverable. Management’s policy in determining whether an impairment indicator exists, a triggering event, comprises measurable operating performance criteria as well as qualitative measures. If an analysis is necessitated by the occurrence of a triggering event, we make certain assumptions in determining the impairment amount. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Goodwill is reviewed for impairment annually, or earlier when events arise that could indicate that an impairment exists. We test for goodwill impairment using a two-step process. The first step compares the fair value of the reporting unit with the unit’s carrying value, including goodwill. When the carrying value of the reporting unit is greater than fair value, the unit’s goodwill may be impaired, and the second step must be completed to measure the amount of the goodwill impairment charge, if any. In the second step, the implied fair value of the reporting unit’s goodwill is compared with the carrying amount of the unit’s goodwill. If the carrying amount is greater than the implied fair value, the carrying value of the goodwill must be written down to its implied fair value. We will continue to perform impairment tests annually, at December 31, and whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. There was no impairment to goodwill as of December 31, 2019.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">DESCRIPTION OF BUSINESS</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">We are a biopharmaceutical company dedicated to developing and delivering medicines for patients with B-cell mediated diseases, including Chronic Lymphocytic Leukemia (CLL), non-Hodgkin Lymphoma (NHL) and Multiple Sclerosis (MS). We have developed a robust B-cell directed research and development (R&amp;D) platform for identification of key B-cell pathways of interest and rapid clinical testing. Currently, we have five B-cell targeted drug candidates in clinical development, with the lead two therapies, ublituximab (TG-1101) and umbralisib (TGR-1202), in pivotal trials for CLL, NHL and MS. Ublituximab is a novel anti-CD20 monoclonal antibody (mAb) that has been glycoengineered for enhanced potency over first generation antibodies. Umbralisib is an oral, once daily, dual inhibitor of PI3K-delta and CK1-epsilon, which may lead to a differentiated safety profile. When used together in combination therapy, ublituximab and umbralisib are referred to as "U2". Additionally, in early clinical development we have an anti-PD-L1 monoclonal antibody referred to as cosibelimab (TG-1501), an oral Bruton’s Tyrosine Kinase (“BTK”) inhibitor referred to as TG-1701, and an anti-CD47/CD19 bispecific antibody referred to as TG-1801.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;margin:0pt;">  </p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">We also actively evaluate complementary products, technologies and companies for in-licensing, partnership, acquisition and/or investment opportunities. To date, we have not received approval for the sale of any of our drug candidates in any market and, therefore, have not generated any product sales from our drug candidates.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;">​</span></p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">LIQUIDITY AND CAPITAL RESOURCES</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We have incurred operating losses since our inception, and expect to continue to incur operating losses for the foreseeable future and may never become profitable. As of December 31, 2019, we have an accumulated deficit of $701.2 million.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Our major sources of cash have been proceeds from the private placement and public offering of equity securities, and in 2019 from our loan and security agreement executed with Hercules Capital, Inc. (“Hercules”) (See Note 7 for more information). We have not yet commercialized any of our drug candidates and cannot be sure if we will ever be able to do so. Even if we commercialize one or more of our drug candidates, we may not become profitable. Our ability to achieve profitability depends on many factors, including our ability to obtain regulatory approval for our drug candidates; successfully complete any post-approval regulatory obligations; and successfully commercialize our drug candidates alone or in partnership. We may continue to incur substantial operating losses even if we begin to generate revenues from our drug candidates.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">As of December 31, 2019, we had $140.4 million in cash and cash equivalents, and investment securities. We anticipate that our cash and cash equivalents, and investment securities as of December 31, 2019 will provide sufficient liquidity for more than a twelve-month period from the date of filing this Annual Report on Form 10-K. The actual amount of cash that we will need to operate is subject to many factors, including, but not limited to, the timing, design and conduct of clinical trials for our drug candidates. We are dependent upon significant future financing to provide the cash necessary to execute our current operations, including the commercialization of any of our drug candidates.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Our common stock is quoted on the Nasdaq Capital Market and trades under the symbol “TGTX.”</p> -701200000 140400000 <p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:0pt;margin:0pt 0pt 12pt 0pt;"><b style="font-weight:bold;">RECENTLY ISSUED ACCOUNTING STANDARDS</b></p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In July 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2018-11, “Leases - Targeted Improvements” (“ASU 2018-11”) as an update to ASU 2016-02, Leases (“ASU 2016-02” or “Topic 842”) issued on February 25, 2016. ASU 2016-02 is effective for public business entities for fiscal years beginning January 1, 2019. ASU 2016-02 required companies to adopt the new leases standard at the beginning of the earliest period presented in the financial statements, which is January 1, 2017, using a modified retrospective transition method where lessees must recognize lease assets and liabilities for all leases even though those leases may have expired before the effective date of January 1, 2017. Lessees must also provide the new and enhanced disclosures for each period presented, including the comparative periods.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">ASU 2018-11 provides an entity with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new lease standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new lease standard will continue to be in accordance with ASC 840, Leases (“ASC 840”). An entity that elects this additional (and optional) transition method must provide the required ASC 840 disclosures for all periods that continue to be in accordance with ASC 840. The amendments do not change the existing disclosure requirements in ASC 840.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">ASU 2018-11 is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with earlier adoption permitted. The Company adopted ASU 2018-11 on January 1, 2019 using a modified retrospective method and will not restate comparative periods. We elected the package of practical expedients permitted under the transition guidance, which allows us to carryforward our historical lease classification and our assessment on whether a contract is or contains a lease. The adoption of this guidance resulted in the addition of material balances of right of use assets and lease liabilities to our consolidated balance sheets at January 1, 2019, primarily relating to our lease of office space (see Note 8). The impact to our consolidated statements of operations was not material as a result of this standard.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In June 2018, the FASB issued ASU No. 2018-07, “Improvements to Nonemployee Share-Based Payment Accounting” (“ASU 2018-07”). ASU 2018-07 expands the scope of FASB Topic 718, Compensation – Stock Compensation (“Topic 718”) to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should only remeasure equity-classified awards for which a measurement date has not been established through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Upon transition, the entity is required to measure these nonemployee awards at fair value as of the adoption date. The entity must not remeasure assets that are completed. Disclosures required at transition include the nature of and reason for the change in accounting principle and, if applicable, quantitative information about the cumulative effect of the change on retained earnings or other components of equity.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">ASU 2018-07 is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company adopted ASU 2018-07 on January 1, 2019. The adoption of ASU 2018-07 did not have a material effect on our consolidated financial statements as of January 1, 2019. The adoption of ASU 2018-07 had no impact on nonemployee performance awards as they are measured based on the outcome that is probable.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Other pronouncements issued by the FASB or other authoritative accounting standards with future effective dates are either not applicable or not significant to our condensed consolidated financial statements.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">USE OF ESTIMATES</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the applicable reporting period. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses and stock-based compensation. Actual results could differ from those estimates. Such differences could be material to the financial statements.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">CASH AND CASH EQUIVALENTS</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We treat liquid investments with original maturities of less than three months when purchased as cash and cash equivalents.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">RESTRICTED CASH</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We record cash pledged or held in trust as restricted cash. As of December 31, 2019 and 2018, we have approximately $1.3 million of restricted cash pledged to secure a line of credit as a security deposit for an Office Agreement (see Note 8).</p> 1300000 1300000 <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">INVESTMENT SECURITIES</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Investment securities at both December 31, 2019 and 2018 consist of short-term government securities. We classify these securities as held-to-maturity. Held-to-maturity securities are those securities in which we have the ability and intent to hold the security until maturity. Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts. Premiums and discounts are amortized or accreted over the life of the related held-to-maturity security as an adjustment to yield using the effective interest method.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">A decline in the market value of any investment security below cost, that is deemed to be other than temporary, results in a reduction in the carrying amount to fair value. The impairment is charged to operations and a new cost basis for the security is established. Other-than-temporary impairment charges are included in interest and other income (expense), net. Dividend and interest income are recognized when earned.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">CREDIT RISK</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and short-term investments. The Company maintains its cash and cash equivalents and short-term investments with high-credit quality financial institutions. At times, such amounts may exceed federally-insured limits.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">REVENUE RECOGNITION</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Effective January 1, 2018, the Company began recognizing revenue under ASC Topic 606, <i style="font-style:italic;">Revenue from Contracts with Customers</i> (“ASC 606”), using the modified retrospective transition method. The impact of adopting the new revenue standard was not material to our consolidated financial statements and there was no adjustment to beginning retained earnings on January 1, 2018. The core principle of this new revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle:</p><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 1: Identify the contract with the customer</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 2: Identify the performance obligations in the contract</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 3: Determine the transaction price</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 4: Allocate the transaction price to the performance obligations in the contract</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Step 5: Recognize revenue when the company satisfies a performance obligation</span></td></tr></table><div style="margin-top:12pt;"/><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In order to identify the performance obligations in a contract with a customer, a company must assess the promised goods or services in the contract and identify each promised good or service that is distinct. A performance obligation meets ASC 606’s definition of a “distinct” good or service (or bundle of goods or services) if both of the following criteria are met:</p><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">The customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer (i.e., the good or service is capable of being distinct).</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">The entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract (i.e., the promise to transfer the good or service is distinct within the context of the contract).</span></td></tr></table><div style="margin-top:12pt;"/><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">If a good or service is not distinct, the good or service is combined with other promised goods or services until a bundle of goods or services is identified that is distinct.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The transaction price is the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties (for example, some sales taxes). The consideration promised in a contract with a customer may include fixed amounts, variable amounts, or both. Variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The transaction price is allocated to each performance obligation on a relative standalone selling price basis. The transaction price allocated to each performance obligation is recognized when that performance obligation is satisfied, at a point in time or over time as appropriate.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">RESEARCH AND DEVELOPMENT COSTS</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Generally, research and development costs are expensed as incurred. Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are deferred and amortized over the period that the goods are delivered or the related services are performed, subject to an assessment of recoverability. We make estimates of costs incurred in relation to external clinical research organizations, or CROs, and clinical site costs. We analyze the progress of clinical trials, including levels of patient enrollment, invoices received and contracted costs when evaluating the adequacy of the amount expensed and the related prepaid asset and accrued liability. Significant judgments and estimates must be made and used in determining the accrued balance and expense in any accounting period. We review and accrue CRO expenses and clinical trial study expenses based on work performed and rely upon estimates of those costs applicable to the stage of completion of a study. Accrued CRO costs are subject to revisions as such trials progress to completion. Revisions are charged to expense in the period in which the facts that give rise to the revision become known. With respect to clinical site costs, the financial terms of these agreements are subject to negotiation and vary from contract to contract. Payments under these contracts may be uneven, and depend on factors such as the achievement of certain events, the successful recruitment of patients, the completion of portions of the clinical trial or similar conditions. The objective of our policy is to match the recording of expenses in our financial statements to the actual services received and efforts expended. As such, expense accruals related to clinical site costs are recognized based on our estimate of the degree of completion of the event or events specified in the specific clinical study or trial contract.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Prepaid research and development in our consolidated balance sheets includes, among other things, costs related to agreements with CRO’s, certain costs to third party service providers related to development and manufacturing services as well as clinical development. These agreements often require payments in advance of services performed or goods received. Accordingly, as of December 31, 2019 and December 31, 2018, we recorded approximately $8.1 million and $9.7 million, respectively, in prepaid research and development related to such advance agreements.</p> 8100000 9700000 <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">INCOME TAXES</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. If the likelihood of realizing the deferred tax assets or liability is less than “more likely than not,” a valuation allowance is then created.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We, and our subsidiaries, file income tax returns in the U.S. Federal jurisdiction and in various states. We have tax net operating loss carryforwards that are subject to examination for a number of years beyond the year in which they were generated for tax purposes. Since a portion of these net operating loss carryforwards may be utilized in the future, many of these net operating loss carryforwards will remain subject to examination. We recognize interest and penalties related to uncertain income tax positions in income tax expense. Refer to Note 9 for further information on impact of tax reform.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">STOCK-BASED COMPENSATION</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We recognize all stock-based payments to employees and non-employee directors (as compensation for service) as noncash compensation expense in the consolidated financial statements based on the fair values of such payments. Stock-based compensation expense recognized each period is based on the value of the portion of stock-based payment awards that is ultimately expected to vest during the period. Forfeitures are recognized as they occur.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In addition, because some of the options, restricted stock and warrants issued to employees, consultants and other third parties vest upon achievement of certain milestones, the total expense is uncertain. Compensation expense for such awards that vest upon the achievement of milestones is recognized when the achievement of such milestones becomes probable.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">BASIC AND DILUTED NET LOSS PER COMMON SHARE</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Basic net loss per share of our common stock is calculated by dividing net loss applicable to the common stock by the weighted-average number of our common stock outstanding for the period. Diluted net loss per share of common stock is the same as basic net loss per share of common stock since potentially dilutive securities from stock options, stock warrants and convertible preferred stock would have an antidilutive effect either because we incurred a net loss during the period presented or because such potentially dilutive securities were out of the money and the Company realized net income during the period presented. The amounts of potentially dilutive securities excluded from the calculation were 8,361,739, 6,528,932 and 4,835,706 at December 31, 2019, 2018 and 2017, respectively. During the years ended December 31, 2019, 2018 and 2017, the Company incurred a net loss, therefore, all of the securities are antidilutive and excluded from the computation of diluted loss per share.</p><table style="border-collapse:collapse;font-size:16pt;margin-left:auto;margin-right:auto;padding-left:0pt;padding-right:0pt;width:100%;"><tr style="height:1pt;"><td

Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Long-lived assets are reviewed for potential impairment when circumstances indicate that the carrying value of long-lived tangible and intangible assets with finite lives may not be recoverable. Management’s policy in determining whether an impairment indicator exists, a triggering event, comprises measurable operating performance criteria as well as qualitative measures. If an analysis is necessitated by the occurrence of a triggering event, we make certain assumptions in determining the impairment amount. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Goodwill is reviewed for impairment annually, or earlier when events arise that could indicate that an impairment exists. We test for goodwill impairment using a two-step process. The first step compares the fair value of the reporting unit with the unit’s carrying value, including goodwill. When the carrying value of the reporting unit is greater than fair value, the unit’s goodwill may be impaired, and the second step must be completed to measure the amount of the goodwill impairment charge, if any. In the second step, the implied fair value of the reporting unit’s goodwill is compared with the carrying amount of the unit’s goodwill. If the carrying amount is greater than the implied fair value, the carrying value of the goodwill must be written down to its implied fair value. We will continue to perform impairment tests annually, at December 31, and whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. There was no impairment to goodwill as of December 31, 2019.</p> 0 <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">NOTE 2 – CASH

The fair value hierarchy ranks the quality and reliability of inputs, or assumptions, used in the determination of fair value and requires financial assets and liabilities carried at fair value to be classified and disclosed in one of the following three categories:</p><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:6pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Level 1 – quoted prices in active markets for identical assets and liabilities;</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:6pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Level 2 – inputs other than Level 1 quoted prices that are directly or indirectly observable; and</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman';font-size:10pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:36pt;"/><td style="font-family:'Times New Roman';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">Level 3 – unobservable inputs that are not corroborated by market data.</span></td></tr></table><div style="margin-top:12pt;"/><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">As of December 31, 2019 and 2018, the fair values of cash and cash equivalents, restricted cash, and notes and interest payable approximate their carrying value.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">At the time of our merger (we were then known as Manhattan Pharmaceuticals, Inc. (“Manhattan”) with Ariston Pharmaceuticals, Inc. (“Ariston”) in March 2010, Ariston issued $15.5 million of five-year 5% notes payable (the “5% Notes”) in satisfaction of several note payable issuances. The 5% Notes and accrued and unpaid interest thereon are convertible at the option of the holder into common stock at the conversion price of $1,125 per share. Ariston agreed to make quarterly payments on the 5% Notes equal to 50% of the net product cash flow received from the exploitation or commercialization of Ariston’s product candidates, AST-726 and AST-915. We have no obligations under the 5% Notes aside from a) 50% of the net product cash flows from Ariston’s product candidates, if any, payable to noteholders; and b) the conversion feature, discussed above.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The cumulative liability including accrued and unpaid interest of the 5% Notes was approximately $19.3 million at December 31, 2019 and $18.4 million at December 31, 2018. No payments have been made on the 5% Notes through December 31, 2019.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In December 2011, we elected the fair value option for valuing the 5% Notes. The fair value option was elected in order to reflect in our financial statements the assumptions that market participants use in evaluating these financial instruments.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">As of December 31, 2013, as a result of expiring intellectual property rights and other factors, it was determined that net product cash flows from AST-726 were unlikely. As we have no other obligations under the 5% Notes aside from the net product cash flows and the conversion feature, the conversion feature was used to estimate the 5% Notes’ fair value as of December 31, 2019 and 2018. The assumptions, assessments and projections of future revenues are subject to uncertainties, difficult to predict, and require significant judgment. The use of different assumptions, applying different judgment to inherently subjective matters and changes in future market conditions could result in significantly different estimates of fair value and the differences could be material to our consolidated financial statements.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 6pt

Subject to the terms and conditions of the Rights Agreement, Rights become exercisable ten days after the public announcement that a “Person” has become an “Acquiring Person” (as each such term is defined in the Rights Agreement).

Under the 2017 S-3, we may sell up to a total of $300 million of securities.

at the conversion price of $1,125 per share. We have no obligation under the 5% Notes aside from (a) 50% of the net product cash flows from Ariston’s product candidates, if any, payable to noteholders; and (b) the conversion feature, discussed above. Interest accrues monthly, is added to principal on an annual basis, every March 8, and is payable at maturity, which was March 8, 2015 (see Note 4 for further details).</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The cumulative liability including accrued and unpaid interest of these notes was approximately $19.3 million at December 31, 2019 and $18.4 million at December 31, 2018. No payments have been made on the 5% Notes through December 31, 2019.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In December 2011, we elected the fair value option for valuing the 5% Notes. The fair value option was elected in order to reflect in our financial statements the assumptions that market participants use in evaluating these financial instruments (see Note 4 for further details).</p><p style="font-family:'Times New Roman';font-size:10pt;font-style:italic;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">Current Liabilities</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In 2018, we entered into an agreement with a contract manufacturer for the clinical and potential commercial supply of one of our product candidates. As part of this agreement, the contract manufacturer has agreed to defer payment of certain costs and expenses under the agreement in exchange for the payment of an administrative fee. To date we have incurred expenses related to this agreement of approximately $47.2 million as of December 31, 2019, which include service fees, raw material costs and administrative fees. No payments have been made to the contract manufacturer as of December 31, 2019. Accordingly, as of December 31, 2019, $47.2 million is included in current liabilities in the Company’s consolidated balance sheet, of which $19.6 million is due in the first quarter of 2020. As of December 31, 2018, $18.4 million is included in long-term liabilities in the Company’s condensed consolidated balance sheet. We will incur an administrative fee of six percent (6%) per year starting from the date of invoice issuance. For the year ended December 31, 2019, we have accrued $1.2 million in administrative fees in connection with these costs, which has been included in interest expense in the Company’s consolidated statements of operations.</p> <p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The following is a summary of notes payable included

2019 (the “Closing Date”), we entered into a term loan facility of up to $60.0 million (“Term Loan”) with Hercules, the proceeds of which were used for research and development programs and for general corporate purposes. The Term Loan is governed by a loan and security agreement, dated February 28, 2019 (the “Loan Agreement”), which provides for up to four separate advances. The first advance of $30.0 million was drawn on the Closing Date. Two additional advances of $10.0 million may be drawn at our option but subject to certain clinical trial milestones, and the fourth advance of $10.0 million, available in minimum increments of $5.0 million, is available through December 15, 2020 subject to the approval of Hercules’ investment committee.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The Term Loan will mature on March 1, 2022 (the “Loan Maturity Date”). Each advance accrues interest at a per annum rate of interest equal to the greater of either (i) the “prime rate” as reported in The Wall Street Journal plus 4.75%, and (ii) 10.25%. The Term Loan provides for interest-only payments until October 1, 2020. The interest-only period may be extended to April 1, 2021 if, on or before September 30, 2020, we achieve either the third milestone or we have raised at least $150.0 million in unrestricted net cash proceeds from one or more equity financings, subordinated indebtedness and/or upfront proceeds from business development transactions permitted under the Loan Agreement, in each case after February 7, 2019, and prior to September 30, 2020 (“Milestone IV”). Thereafter, amortization payments will be payable monthly in eighteen installments (or, if the period requiring interest-only payments has been extended to April 1, 2021, in twelve installments) of principal and interest (subject to recalculation upon a change in prime rates). As a result of the Company having raised in excess of $150 million before the required timeline in the Loan Agreement, the interest-only period has been extended to April 1, 2021. At our option upon seven business days’ prior written notice to Hercules, we may prepay all or any portion greater than or equal to $5.0 million of the outstanding advances by paying the entire principal balance (or portion thereof), all accrued and unpaid interest, subject to a prepayment charge of 3.0%, if such advance is prepaid in any of the first twelve months following the Closing Date; 1.5%, if such advance is prepaid after twelve months following the Closing Date but on or prior to twenty-four months following the Closing Date; and 0% thereafter. In addition, a final payment equal to 3.5% of the aggregate principal amount of the loan extended by Hercules is due on the maturity date. Amounts outstanding during an event of default shall be payable on demand and accrue interest at an additional rate of 4.0% per annum of the past due amount outstanding.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The Term Loan is secured by a lien on substantially all of our assets, other than intellectual property and contains customary covenants and representations, including a liquidity covenant, financial reporting covenant and limitations on dividends, indebtedness, collateral, investments, distributions, transfers, mergers or acquisitions, taxes, corporate changes, deposit accounts, and subsidiaries. As of and through December 31, 2019, the Company has been in compliance with all covenants.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The events of default under the Loan Agreement include, without limitation, and subject to customary grace periods, (1) our failure to make any payments of principal or interest under the Loan Agreement, promissory notes or other loan documents, (2) our breach or default in the performance of any covenant under the Loan Agreement, (3) the occurrence of a material adverse effect, (4) a false or misleading representation or warranty in any material respect, (5) our insolvency or bankruptcy, (6) certain attachments or judgments on the Borrower’s assets, or (7) the occurrence of any material default under certain agreements or obligations involving indebtedness in excess of $750,000. If an event of default occurs, Hercules is entitled to take enforcement action, including acceleration of amounts due under the Loan Agreement.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The Loan Agreement also contains warrant coverage of 2% of the total amount funded. A warrant (the “Hercules Warrant”) was issued to Hercules to purchase 147,058 shares of common stock with an exercise price of $4.08. The Hercules Warrant is exercisable for seven years from the date of issuance. Hercules may exercise the Hercules Warrant either by (a) cash or check or (b) through a net issuance conversion. The shares will be registered and freely tradeable within six months of issuance. We accounted for the Hercules Warrant as an equity instrument since it was indexed to our common shares and met the criteria for classification in shareholders equity. The relative fair value of the Hercules Warrant on the date of issuance was approximately $1.0 million and was treated as debt issuance costs and as an offset to the Term Loan. This amount will be amortized to interest expense using the straight-line method, which approximates the effective interest method, over the life of the Term Loan.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The Company estimated the fair value of the Hercules Warrant using the Black-Scholes model based on the following key assumptions:</p><table style="border-collapse:collapse;font-size:16pt;padding-left:0pt;padding-right:0pt;width:100%;"><tr style="height:1pt;"><td

style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In October 2014, we entered into an agreement (the “Office Agreement”) with Fortress Biotech, Inc. (“FBIO”) to occupy approximately 45% of the 24,000 square feet of New York City office space leased by FBIO. The Office Agreement requires us to pay our respective share of the average annual rent and other costs of the <span style="-sec-ix-hidden:_1be1db85_1ccc_4c6f_ac19_9d729d06e6cb"><span style="color:#000000;font-family:'Times New Roman';font-size:10pt;font-style:normal;font-weight:normal;text-align:justify;">15-year</span></span> lease. We approximate an average annual rental obligation of $1.4 million under the Office Agreement. We began to occupy this new space in April 2016, with rental payments beginning in the third quarter of 2016. At January 1, 2019, we recognized a lease liability and corresponding Right of Use (“ROU”) asset of $9.5 million and $8.1 million, respectively, based on the present value of the remaining lease payments for all of our leased office spaces, the majority of which is comprised of our New York City office space. The present values of our lease liability and corresponding ROU asset are $11.8 million and $9.4 million, respectively, as of December 31, 2019. Our leases have remaining lease terms of 4 months to 12 years. One lease has a renewal option to extend the lease for an additional term of 2 years.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The initial commitment period of the 45% rate was for a period of three (3) years. We and FBIO currently determine actual office space utilization annually and if our utilization differs from the amount we have been billed, we will either receive credits or be assessed incremental utilization charges. As of December 31, 2019, the allocation rate is 61% and will be evaluated again in August 2020 for the following rent year. Also in connection with this lease, in October 2014 we pledged $0.6 million to secure a line of credit as a security deposit for the Office Agreement, which has been recorded as restricted cash in the accompanying consolidated balance sheets. Additional collateral of $0.6 million was pledged in April 2018 to increase the letter of credit for the office space.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In October 2019, we finalized a five-year lease for office space in New Jersey (the “NJ Lease”). We approximate an average annual rental obligation of $0.3 million under the NJ Lease. We took possession of this space in October 2019, with rental payments beginning in November 2019.</p><p style="font-family:'Times New

Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized. In determining the need for a valuation allowance, management reviews both positive and negative evidence, including current and historical results of operations, future income projections and the overall prospects of our business. Based upon management’s assessment of all available evidence, we believe that it is more-likely-than-not that the deferred tax assets will not be realizable, and therefore, a valuation allowance has been established. The valuation allowance for deferred tax assets was approximately $186,711,000 and $142,947,000 as of December 31, 2019 and 2018, respectively.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">On December 22, 2017, H.R.1, commonly known as the Tax Cuts and Jobs Act (the “Act”) was signed into law. Among other things, the Act reduced our corporate federal tax rate from 34% to 21% effective January 1, 2018. As a result, we were required to re-measure, through income tax expense, our deferred tax assets and liabilities using the enacted rate at which we expect them to be recovered or settled. The re-measurement of our net deferred tax asset would have resulted in additional income tax expense of $51,767,584 as of December 31, 2017; however, with full valuation allowance in place, the expense was reversed through a corresponding adjustment to the valuation allowance, resulting in no impact on income tax expense.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">As of December 31, 2019, we have U.S. net operating loss carryforwards (“NOLs”) of approximately $709,949,000, research and development credit carryforwards (“R&amp;D credits”) of approximately $22,483,000 and business interest expense carryforward of $3,189,000.  For income tax purposes, these NOLs and R&amp;D credits will expire in various amounts through 2037. NOLs generated after 2017 and the business interest expense carryforwards do not expire. The Tax Reform Act of 1986 contains provisions which limit the ability to utilize net operating loss carryforwards and R&amp;D credit carryforwards in the case of certain events including significant changes in ownership interests.  The Exchange Transaction with TG Bio may have resulted in a “change in ownership” as defined by IRC Section 382 of the Internal Revenue Code of 1986, as amended. Additionally, stock issuance activities may have resulted in a “change in ownership” as defined by IRC Section 382 of the Internal Revenue Code of 1986, as amended.  Accordingly, a substantial portion of the Company’s NOLs above may be subject to annual limitations in reducing any future year’s taxable income, and a substantial portion of the R&amp;D Credit carryforwards may be subject to annual limitations in reducing any future year’s tax.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2019 and 2018 are presented below.</p><table

(Ublituximab)</span></p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In November 2012, we entered into an exclusive (within the territory) sublicense agreement with Ildong Pharmaceutical Co. Ltd. (“Ildong”) relating to the development and commercialization of ublituximab in South Korea and Southeast Asia. Under the terms of the sublicense agreement, Ildong has been granted a royalty bearing, exclusive right, including the right to grant sublicenses, to develop and commercialize ublituximab in South Korea, Taiwan, Singapore, Indonesia, Malaysia, Thailand, Philippines, Vietnam, and Myanmar.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">An upfront payment of $2.0 million, which was received in December 2012, net of $0.3 million of income tax withholdings, is being recognized as license revenue on a straight-line basis over the life of the agreement, which is through the expiration of the last licensed patent right or 15 years after the first commercial sale of a product in such country, unless the agreement is earlier terminated, and represents the estimated period over which we will have certain ongoing responsibilities under the sublicense agreement. We recorded license revenue of approximately $152,000 for each of the years ended December 31, 2019 and 2018, and, at December 31, 2019 and 2018, have deferred revenue of approximately $0.9 million and $1.1 million, respectively, associated with this $2 million payment (approximately $152,000 of which has been classified in current liabilities at December 31, 2019 and 2018).</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">We may receive up to an additional $5.0 million in payments upon the achievement of pre-specified milestones. In addition, upon commercialization, Ildong will make royalty payments to us on net sales of ublituximab in the sublicense territory.</p><p style="font-family:'Times New Roman';font-size:10pt;font-style:italic;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">TGR-1202 (Umbralisib)</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">On September 22, 2014, we exercised our option to license the global rights to umbralisib, thereby entering into an exclusive licensing agreement (the “TGR-1202 License”) with Rhizen Pharmaceuticals, SA (“Rhizen”) for the development and commercialization of umbralisib. Prior to this, we had been jointly developing umbralisib in a 50:50 joint venture with Rhizen.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Under the terms of the TGR-1202 License, Rhizen received a $4.0 million cash payment and 371,530 shares of our common stock as an upfront license fee. With respect to umbralisib, Rhizen will be eligible to receive regulatory filing, approval and sales-based milestone payments in the aggregate of approximately $175 million, a small portion of which will be payable on the first New Drug Application (NDA) filing and the remainder on approval in multiple jurisdictions for up to two oncology indications and one non-oncology indication and attaining certain sales milestones. In addition, if umbralisib is co-formulated with another drug to create a new product (a "New Product"), Rhizen will be eligible to receive similar regulatory approval and sales-based milestone payments for such New Product. Additionally, Rhizen will be entitled to tiered royalties on our future net sales of umbralisib and any New Product. In lieu of sales milestones and royalties on net sales, Rhizen shall also be eligible to participate in sublicensing revenue, if any, based on a percentage that decreases as a function of the number of patients treated in clinical trials following the exercise of the license option. Rhizen will retain global manufacturing rights to umbralisib, provided that they are price competitive with alternative manufacturers.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-style:italic;font-weight:bold;">TG-1501: PDL1 (Cosibelimab)</span></p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;margin:0pt;"><span style="font-style:italic;font-weight:bold;visibility:hidden;">​</span></p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">In March 2015, we entered into a Global Collaboration Agreement (“Collaboration Agreement”) with Checkpoint for the development and commercialization of anti-PD-L1 and anti-GITR antibody research programs in the field of hematological malignancies. The Collaboration Agreement was amended in June 2019 and upon execution of the amendment we incurred an upfront fee of $1.0 million. We incurred expenses of approximately $4.1 million and $0.6 million for the years ended December 31, 2019 and 2018, the majority of which relates to manufacturing expenses of PD-L1.

(“Hengrui”), to acquire worldwide intellectual property rights, excluding Asia but including Japan, and for the research, development, manufacturing, and commercialization of products containing or comprising of any of Hengrui’s Bruton’s Tyrosine Kinase inhibitors containing the compounds of either TG-1701 (SHR1459 or EBI1459) or TG1702 (SHR1266 or EBI1266). Pursuant to the agreement, in April 2018, we paid Jiangsu an upfront fee of $1.0 million in our common stock recorded to noncash stock expense associated with in-licensing agreements in our condensed consolidated statement of operations. In addition, in July 2019, we paid Jiangsu the first milestone of $0.1 million in our common stock recorded to noncash stock expense associated with in-licensing agreements in our consolidated statement of operations. Jiangsu is eligible to receive milestone payments totaling approximately $350 million upon and subject to the achievement of certain milestones. Various provisions allow for payments in conjunction with the agreement to be made in cash or our common stock, while others limit the form of payment. Royalty payments in the low double digits are due on net sales of licensed products and revenue from sublicenses.</p><p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">TG-1801: anti-CD47/anti-CD19</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In June 2018, we entered into a Joint Venture and License Option Agreement with Novimmune SA (“Novimmune”) to collaborate on the development and commercialization of Novimmune’s novel first-in-class anti-CD47/anti-CD19 bispecific antibody known as TG-1801 (previously NI-1701). The companies will jointly develop the product on a worldwide basis, focusing on indications in the area of hematologic B-cell malignancies. We serve as the primary responsible party for the development, manufacturing and commercialization of the product. Pursuant to the agreement, in June 2018 we paid Novimmune an upfront payment of $3.0 million in our common stock recorded to noncash stock expense associated with in-licensing agreements in our consolidated statement of operations. Further milestone payments will be paid based on early clinical development, and the Company will be responsible for the costs of clinical development of the product through the end of the Phase 2 clinical trials, after which the Company and Novimmune will be jointly responsible for all development and commercialization costs. The Company and Novimmune will each maintain an exclusive option, exercisable at specific times during development, for the Company to license the rights to TG-1801, in which case Novimmune is eligible to receive additional milestone payments totaling approximately $185 million as well as tiered royalties on net sales in the high single to low double digits upon and subject to the achievement of certain milestones.</p> 2000000.0 300000 P15Y 152000 152000 900000 1100000 2000000 152000 152000 5000000.0 4000000.0 371530 175000000 2 1 1000000.0 4100000 600000 1000000.0 177000000 1000000.0 100000 350000000 3000000.0 185000000 <p style="font-family:'Times New Roman';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">NOTE 11 – RELATED PARTY TRANSACTIONS</p><p style="font-family:'Times New Roman';font-size:10pt;font-style:italic;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;">Other Parties</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In October 2014, we entered into the Office Agreement with FBIO, to occupy approximately 45% of the 24,000 square feet of New York City office space leased by FBIO.

We approximate an average annual rental obligation of $1.1 million under the Office Agreement. We began to occupy this new space in April 2016, with rental payments beginning in the third quarter of 2016. At January 1, 2019, we recognized a lease liability of $9.3 million, with a corresponding Right of Use (ROU) asset of $7.7 million based on the present value of the remaining lease payments for all of our leased office spaces, the majority of which is comprised of our New York City office space.

We and FBIO currently determine actual office space utilization annually and if our utilization differs from the amount we have been billed, we will either receive credits or be assessed incremental utilization charges. As of December 31, 2019, the allocation rate is 61% and will be evaluated again in August 2020 for the following rent year. Also, in connection with this lease, in October 2014 we pledged $0.6 million to secure a line of credit as a security deposit for the Office Agreement, which has been recorded as restricted cash in the accompanying consolidated balance sheets. Additional collateral of $0.6 million was pledged in April 2018 to increase the letter of credit for the office space.</p><p style="font-family:'Times New Roman';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In July 2015, we entered into a Shared Services Agreement (the “Shared Services Agreement”) with FBIO to share the cost of certain services such as facilities use, personnel costs and other overhead and administrative costs.
