TG Therapeutics Provides Business Update and Reports Third Quarter 2020 Financial Results

New York, NY, (November 9, 2020)– TG Therapeutics, Inc. (NASDAQ: TGTX) today announced its financial results for the third quarter ended September 30, 2020 and recent company developments.

Michael S. Weiss, the Company's Executive Chairman and Chief Executive Officer, stated, “This has been a very exciting few months for TG especially sharing the first ever data from the UNITY-CLL Phase 3 trial last week showing that the trial met its primary endpoint of improvement in progression-free survival, as well as data from the UNITY-NHL trial which supported our NDA submission for umbralisib monotherapy. These data sets add to the growing body of evidence suggesting that umbralisib has a differentiated safety profile and support our long-term vision of U2 as a potential backbone for future combination therapies.” Mr. Weiss continued, “With PDUFA goal dates in February 2021 and June 2021 now set for our umbralisib NDA for the treatment of relapsed/refractory MZL and FL, respectively, our team is hard at work ensuring we are prepared for a successful launch in these indications. With a healthy balance sheet which includes a proforma cash position of approximately $325 million as of September 30, 2020, we are focused on preparing a BLA/NDA submission for U2 in CLL and importantly delivering on our remaining milestones for the year including topline results from our ULTIMATE I & II Phase 3 trials of ublituximab in MS.”

Recent Developments and Highlights

·      ASH 2020 Presentations:

o     Four abstracts have been accepted for presentation at the upcoming 62^nd American Society of Hematology (ASH) annual meeting, to be held virtually December 5 – 8, 2020, including:

·      Results from the UNITY-NHL Phase 2 marginal zone lymphoma (MZL) and follicular lymphoma (FL) umbralisib monotherapy cohorts

·      Results from the UNITY-CLL Phase 3 trial evaluating the combination of umbralisib
and ublituximab (U2) in patients with treatment naïve and relapsed/refractory chronic lymphocytic leukemia (CLL)

·      Two triple therapy presentations, one evaluating the combination of U2 plus venetoclax in CLL, and a another evaluating the combination of U2 plus TG-1701, our BTK inhibitor, in patients with B-cell malignancies

o     Abstracts were made available last week and a call was held with leading investigators from our trials to review the data included in these abstracts. A replay from this call is available on our corporate website at https://ir.tgtherapeutics.com/events.

·      UNITY-NHL: Umbralisib Monotherapy Marginal Zone Lymphoma & Follicular Lymphoma Cohorts

o     In July 2020, we announced the publication of preclinical data describing the unique immunomodulatory effects of umbralisib in Blood Advances, a Journal of the American Society of Hematology.

​

​

·      UNITY-CLL: Ublituximab and Umbralisib (U2) in Chronic Lymphocytic Leukemia

o     In October, the FDA granted Fast Track Designation to the combination of ublituximab and umbralisib (U2) for the treatment of adult patients with CLL, which could potentially expedite the development and regulatory review of U2. The application for Fast Track was based on data from the UNITY-CLL Phase 3 Study.

Key Objectives for Remainder of 2020 and Early 2021

·      Report topline results from the Phase 3 ULTIMATE I & II trials in Multiple Sclerosis

·      Present full data from the UNITY-CLL Phase 3 trial and from the FL and MZL single agent umbralisib cohorts of the UNITY-NHL trial at ASH 2020 as well as data from our triple therapy combinations of U2 plus venetoclax and U2 plus 1701, our BTK inhibitor

·      Target an NDA/Biologics Licensing Application (BLA) submission of U2 for the treatment of patients with CLL (including both previously untreated and relapsed/refractory patients)

·      Complete enrollment in ULTRA-V Phase 2b trial

·      Continue to advance our early pipeline candidates including our anti-PD-L1 monoclonal antibody, cosibelimab (TG-1501), our covalently-bound Bruton’s Tyrosine Kinase (BTK) inhibitor, TG-1701, and our anti-CD47/CD19 bispecific antibody, TG-1801

Financial Results for the Three and Nine Months Ended September 30, 2020

·      R&D Expenses: Other research and development (R&D) expense (not including non-cash compensation) was $45.8 million and $114.8 million for the three and nine months ended September 30, 2020, respectively, compared to $56.5 million and $118.8 million for the three and nine months ended September 30, 2019, respectively. The decrease in R&D is primarily attributable to a decrease in manufacturing costs for ublituximab and umbralisib, offset by an increase in milestone payments made during the three and nine months ended September 30, 2020. We expect our R&D expenses to decrease during the remainder of 2020 as costs associated with our main pivotal clinical trials continue to decline, partially offset by expenses associated with the expected NDA/BLA filing for U2 in CLL.

​

·      G&A Expenses: Other general and administrative (G&A) expense (not including non-cash compensation) was $11.6 million and $25.4 million for the three and nine months ended September 30 2020, respectively, as compared to $2.3 million and $6.6 million for the three and nine months ended September 30, 2019, respectively. The increase in other G&A expenses is primarily due to increased personnel and other general and administrative costs, associated with preparations for a potential commercial launch. We expect G&A expenses to increase modestly during the remainder of 2020 in preparation for potential launch.

​

·      Net Loss: Net loss was $87.2 million and $191.2 million for the three and nine months ended September 30, 2020, respectively, compared to a net loss of $61.9 million and $133.3 million for the three and nine months ended September 30, 2019, respectively. The net loss for the nine months ended September 30, 2020 included approximately $15 million of one-time milestone expenses related to our license agreements. Excluding non-cash compensation, the net loss for the three and nine months ended September 30, 2020 was approximately $58.8 million and $144.4 million, respectively, compared to a net loss of $59.9 million and $127.6 million for the three and nine months ended September 30, 2019, respectively.

·      Cash Position and Financial Guidance: Cash and cash equivalents were $254.2 million as of September 30, 2020. Pro forma cash, cash equivalents and investment securities as of September 30, 2020 are approximately $328 million, after giving effect to $74.0 million of net proceeds from the utilization of the Company's ATM sales facility during the fourth quarter of 2020. The Company believes its cash and cash equivalents on hand as of September 30, 2020, along with the additional capital raised in the fourth quarter of 2020, will be sufficient to fund the Company's planned operations well into 2022.
