TG Therapeutics, Inc. Announces Publication of Clinical Data from the Phase I Triple Therapy Combination Trial of Ublituximab, Umbralisib, and Ibrutinib in The Lancet Haematology
Jan 30, 2019
The paper includes safety and efficacy information from patients with relapsed or refractory B-cell malignancies, including 23 patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) and 23 patients with non-Hodgkin lymphoma (
These data are described further in the manuscript entitled, “Tolerability and activity of ublituximab, umbralisib, and ibrutinib in patients with chronic lymphocytic leukemia and non-Hodgkin lymphoma: a phase 1 dose escalation and expansion trial,” which was featured as the cover article in the February issue of The Lancet Hematology published yesterday.

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.

In addition to the risk factors identified from time to time in our reports filed with the Securities and Exchange Commission, factors that could cause our actual results to differ materially are the following: our ability to successfully and cost effectively complete preclinical and clinical trials; the risk that early preclinical and clinical trial results, that may have supported the acceptance of our data for publication or influenced our decision to proceed with additional clinical trials, will not be reproduced in future studies or in future data presentations; the risk that umbralisib will not maintain its differentiated safety profile as patients continue to be treated on drug for longer durations and more patients are enrolled; the risk that the combination of ublituximab (TG-1101) and umbralisib (TGR-1202), referred to as U2 and being studied in the UNITY clinical trials, will not prove to be a safe and efficacious combination, or backbone for triple therapy combinations; the risk that we will not commence clinical trials of umbralisib plus TG-1701 or of U2 plus TG-1701; the risk that the early data seen with TG-1701 will not be reproduced in future trials. Any forward-looking statements set forth in this press release speak only as of the date of this press release. We do not undertake to update any of these forward-looking statements to reflect events or circumstances that occur after the date hereof.
