NEW YORK, Feb. 22, 2019 (GLOBE NEWSWIRE) -- TG Therapeutics, Inc. (NASDAQ: TGTX), today announced that the final Phase 2 data from the multicenter trial of ublituximab (TG-1101), the Company’s novel glycoengineered anti-CD20 monoclonal antibody, in relapsing forms of Multiple Sclerosis (RMS) has been selected for presentation at the upcoming Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) annual meeting, to be held February 28 through March 2, 2019 in Dallas, Texas. This data was previously presented at the 34th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) meeting held in October of 2018.

Abstracts are now available online and can be accessed on the ACTRIMS meeting website at www.forum.actrims.org. Highlights from the abstract and details of the poster presentation are outlined below.

Abstract Highlights:

  • An Annualized Relapse Rate (ARR) of 0.07 was observed for all patients
  • Ublituximab completely eliminated all (100%) of T1 Gd-enhancing lesions at week 24 (n=44) and maintained at week 48 (n=22)
  • Median B cell depletion was >99% at the primary analysis point of Week 4, and maintained at Week 24 (n=44) and Week 48 (n=22)
  • Ublituximab was well tolerated with no discontinuations due to severe adverse events (SAE’s) reported and accelerated infusions times as short as 1 hour for the 450mg Phase 3 dose

Presentation Details:

These data support the ongoing, fully enrolled, international Phase 3 program evaluating ublituximab (TG-1101) for the treatment of relapsing form of Multiple Sclerosis (RMS). The Phase 3 trials, entitled ULTIMATE I and ULTIMATE II, are being conducted under Special Protocol Assessment (SPA) agreement with the U.S. Food and Drug Administration (FDA) and are being led by Lawrence Steinman, MD, of Stanford University.

ABOUT TG THERAPEUTICS, INC.

TG Therapeutics is a biopharmaceutical company focused on the acquisition, development and commercialization of novel treatments for B-cell malignancies and autoimmune diseases. Currently, the company is developing two therapies targeting hematological malignancies and autoimmune diseases. Ublituximab (TG-1101) is a novel, glycoengineered monoclonal antibody that targets a specific and unique epitope on the CD20 antigen found on mature B-lymphocytes. TG Therapeutics is also developing umbralisib (TGR-1202), an oral, once-daily inhibitor of PI3K-delta. Umbralisib uniquely inhibits CK1-epsilon, which may allow it to overcome certain tolerability issues associated with first generation PI3K-delta inhibitors. Both ublituximab and umbralisib, or the combination of which is referred to as "U2", are in Phase 3 clinical development for patients with hematologic malignancies, with ublituximab also in Phase 3 clinical development for Multiple Sclerosis. Additionally, the Company has recently brought its anti-PD-L1 monoclonal antibody, TG-1501, as well as its covalently-bound Bruton Tyrosine Kinase (BTK) inhibitor, TG-1701, into Phase 1 development and aims to bring additional pipeline assets into the clinic in the future. TG Therapeutics is headquartered in New York City.

Cautionary Statement

Statements included in this press release, particularly those with respect to anticipating the benefit of the data seen in the Phase 2 MS trial program and performance in of ublituximab in the Phase 3 ULTIMATE clinical program may be forward-looking statements that involve a number of risks and uncertainties. For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. Among the factors that could cause our actual results to differ materially are the following: the risk that early clinical results that supported our decision to move forward will not be reproduced in additional patients in expansion cohorts or in the MS Phase 3 program; the risk that data included in the abstract submission will not be reproduced in the full data presentation; the risk that the clinical results from the MS Phase 3 program, will not be positive and/or will not support regulatory approval of ublituximab to treat MS; our ability to successfully and cost-effectively complete the MS Phase 3 trials; the risk that ublituximab will not have a differentiated profile from the other drugs in the class and that early signs of best-in-class attributes will not be supported by future results; the risk that trials will take longer to enroll than expected; our ability to achieve the milestones we project over the next year; our ability to manage our cash in line with our projections, and other risk factors identified from time to time in our reports filed with the Securities and Exchange Commission. Any forward-looking statements set forth in this press release speak only as of the date of this press release.
