Follicular lymphoma cohort met the primary endpoint of overall response rate (ORR)

Umbralisib monotherapy appeared to be well tolerated with a safety profile consistent with previous reports

TG plans to present the data at a future medical conference and discuss the results with the FDA

NEW YORK (GLOBE NEWSWIRE) --  TG Therapeutics, Inc. (NASDAQ: TGTX), a biopharmaceutical company developing medicines for patients with B-cell mediated diseases, today announced that the follicular lymphoma (FL) cohort of the UNITY-NHL Phase 2b pivotal trial evaluating single agent umbralisib, the Company’s novel, once daily, PI3K delta inhibitor, met the primary endpoint of overall response rate (ORR) as determined by Independent Review Committee (IRC) for all treated patients (n=118) who have received at least two prior lines of therapy including an anti-CD20 monoclonal antibody and an alkylating agent. The results met the Company’s prespecified ORR target of 40-50%. Importantly, umbralisib monotherapy appeared to be well tolerated with a safety profile consistent with previous reports.

The Company plans to present the data at a future medical conference as well as discuss the data with the U.S. Food and Drug Administration (FDA).

Michael S. Weiss, Executive Chairman and Chief Executive Officer of TG Therapeutics stated, “We are extremely pleased to announce that the UNITY-NHL follicular lymphoma cohort evaluating umbralisib monotherapy met the primary endpoint of ORR. There are no fully approved drugs for patients with follicular lymphoma that have progressed following two or more prior lines of therapy and we are excited by the potential to offer a novel treatment for this underserved population. We look forward to sharing these results with the FDA and discussing submission opportunities for accelerated approval of umbralisib in follicular lymphoma."  Mr. Weiss continued, “These are very exciting times for TG and with two additional major events targeted to occur over the next several months, including commencing our first NDA filing  for umbralisib in patients with relapsed/refractory marginal zone lymphoma and results from our UNITY-CLL Phase 3 trial, we expect that excitement to continue. Taken together, we see 2020 shaping up as a pivotal year where we transition from a development-stage company into a fully-integrated development and commercial organization.”
