Press Release

TG Therapeutics, Inc. Announces Successful Outcome from the First Pre-Planned Interim Analysis by Independent DSMB of the DLBCL Cohort in the UNITY-NHL Phase 2b Trial


Posted on: 10 Aug 17

Based on pre-set hurdles of Overall Response Rate (ORR) the DSMB recommends continued enrollment in the TGR-1202 + TG-1101 (“U2”) arm and no further enrollment into the single agent TGR-1202 arm

As set forth in the protocol, single agent TGR-1202 arm will be replaced with the triple combination of TG-1101, TGR-1202 and bendamustine

NEW YORK, Aug. 10, 2017 (GLOBE NEWSWIRE) -- TG Therapeutics, Inc. (NASDAQ:TGTX), today announced that the independent Data Safety Monitoring Board (DSMB) of the UNITY-NHL Phase 2b registration directed trial has successfully completed the first pre-specified interim analysis to evaluate the Overall Response Rate (ORR) in the cohort enrolling patients with relapsed or refractory Diffuse Large B-cell Lymphoma (DLBCL) that are not eligible for high-dose chemotherapy or transplant.  Upon review of the available ORR data, based on pre-specified efficacy thresholds of ORR, the DSMB recommended the Company cease enrollment into the single agent TGR-1202 arm, while continuing enrollment into the TG-1101 + TGR-1202 arm which has demonstrated an acceptable level of efficacy to warrant continued evaluation.  Per the UNITY-NHL protocol, the single agent TGR-1202 arm will be replaced by an arm evaluating the triple combination arm of TG-1101, TGR-1202, and bendamustine.

Michael S. Weiss, the Company’s Executive Chairman and Chief Executive Officer stated, “The DLBCL cohort in our UNITY-NHL trial was designed to evaluate the contribution of TGR-1202 in our combination ‘U2’ regimen.  We are extremely pleased that the DSMB has recommended continued enrollment in the U2 arm, while allowing us to proceed with replacing the single agent TGR-1202 arm with the triple combination of TG-1101, TGR-1202, and bendamustine (also referred to as U2 + Benda) as planned.  As recently presented, the triplet combination of U2 + Benda was highly active, with a 50% ORR in patients with refractory DLBCL and a 100% ORR in relapsed DLBCL patients.  We have long believed that patients with aggressive DLBCL in particular are best treated with combination therapy rather than single agents and are pleased to see our UNITY-NHL study advancing to the next level.”

ABOUT UNITY-NHL PHASE 2b TRIAL

UNITY-NHL is a global Phase 2b clinical trial evaluating TG-1101 and TGR-1202, (“U2”), in patients with various types of B-cell lymphoma.  The trial consists of three independent cohorts enrolling patients with relapsed or refractory Diffuse Large B-cell Lymphoma (DLBCL), Follicular Lymphoma (FL), Small Lymphocytic Lymphoma (SLL), and Marginal Zone Lymphoma (MZL).  The study is evaluating the U2 combination and the combination of U2 + bendamustine in patients with DLBCL; TGR-1202 monotherapy and in the U2 combination in patients with FL and SLL; and TGR-1202 monotherapy in patients with MZL.

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.

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 TG-1101 and TGR-1202 are in clinical development for patients with hematologic malignancies, with TG-1101 also in clinical development for autoimmune disorders. The Company also has pre-clinical programs to develop IRAK4 inhibitors, BET inhibitors, and anti-PD-L1 and anti-GITR antibodies. TG Therapeutics is headquartered in New York City.
