TG Therapeutics Announces Update Regarding UNITY-CLL Phase 3 Trial
Sep 25, 2018
Additionally, the DSMB reviewed safety data from over 600 patients, including over 300 patients treated with umbralisib either alone or in combination with ublituximab, of which approximately 60% were treatment naïve. While no evaluation of PFS was conducted, the DSMB had PFS information available to them solely for purposes of assessing the overall benefit-risk. After review of the data, the DSMB identified no safety concerns and recommended the trial continue without modification. The UNITY-CLL Phase 3 trial continues to be conducted under Special Protocol Assessment (SPA) agreement with the

ABOUT UNITY-CLL PHASE 3 TRIAL
UNITY-CLL is a global Phase 3 randomized controlled clinical trial comparing the combination of ublituximab plus umbralisib, or U2, to an active control arm of obinutuzumab plus chlorambucil in patients with both treatment naïve and relapsed or refractory Chronic Lymphocytic Leukemia (CLL). The trial randomized patients into four treatment arms: ublituximab single agent, umbralisib single agent, ublituximab plus umbralisib and an active control arm of obinutuzumab plus chlorambucil. A pre-specified analysis was conducted to assess the contribution of ublituximab and umbralisib in the combination regimen of ublituximab plus umbralisib and allowed for the termination of the single agent arms. Accordingly, the UNITY-CLL Phase 3 trial continued enrollment in a 1:1 ratio into the two combination arms: the investigational arm of U2 and the control arm of obinutuzumab plus chlorambucil. Full enrollment into the UNITY-CLL Phase 3 trial completed in October of 2017. This trial enrolled approximately 60% treatment naïve CLL patients and 40% relapsed refractory CLL patients. The primary endpoint for this study is to demonstrate superiority in Progression Free Survival (PFS) for the U2 combination over the control arm to support the submission for full approval of the U2 combination in CLL. The UNITY-CLL Phase 3 trial is being conducted under Special Protocol Assessment (SPA) agreement with the

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 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.
