TG Therapeutics, Inc. Announces Follow-Up Data from the Triple Combination of Ublituximab, Umbralisib, and Bendamustine in Patients with DLBCL and FL at 60th American Society of Hematology Annual Meeting and Exposition
NEW YORK, Dec. 04, 2018 (GLOBE NEWSWIRE) -- TG Therapeutics, Inc. (NASDAQ: TGTX), today announced updated clinical data from its Phase I/Ib trial of ublituximab (TG-1101), the Company’s novel glycoengineered anti-CD20 monoclonal antibody in combination with umbralisib (TGR-1202), the Company’s oral, next generation PI3K delta inhibitor, and bendamustine, in patients with Diffuse Large B-cell Lymphoma (DLBCL) and Follicular Lymphoma (FL). Data from this trial was presented yesterday evening during a poster session at the 60th American Society of Hematology (ASH) Annual Meeting and Exposition.
Michael S. Weiss, the Company's Executive Chairman and Chief Executive Officer stated, “The data presented yesterday further supports our belief that our proprietary U2 combination is an ideal backbone regimen on which to build novel multi-drug combinations. The triple therapy of U2 plus bendamustine is highly active and well tolerated in advanced patients, resulting in durable responses with some patients on study 36+ months.” Mr. Weiss continued, “We are looking forward to an exciting 2019, with pivotal data expected from the ongoing UNITY-NHL registration directed program in the first half of the year.”
Below summarizes the data from the poster presentation.
Combination of Umbralisib, Ublituximab, and Bendamustine is Safe and Highly Active in Patients with Advanced DLBCL and Follicular Lymphoma (Abstract 4197)
This poster presentation includes data from patients with relapsed or refractory DLBCL or FL treated with the triple combination of umbralisib, ublituximab and bendamustine. Thirty-nine patients were evaluable for safety of which 38 were evaluable for efficacy (one patient discontinued due to a treatment-related adverse event (AE), neutropenia, prior to first efficacy assessment). Twenty-two patients (56%) were refractory to prior treatment. Overall, the triple combination was well tolerated and highly active in patients with advanced indolent and aggressive NHL, including those not eligible for HD/SCT or CD19 CART therapy.
Efficacy highlights from this poster include:
- 85% (11 of 13) ORR, including a 54% CR rate, observed in patients with relapsed or refractory FL
- 48% (12 of 25) ORR, including a 36% CR rate, observed in patients with relapsed or refractory DLBCL

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 orally available PI3K delta inhibitor. The delta isoform of PI3K is strongly expressed in cells of hematopoietic origin and is believed to be important in the proliferation and survival of B‐lymphocytes. 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.
