[{"type":"text","content":"NEW YORK, June 22, 2020 (GLOBE NEWSWIRE) -- TG Therapeutics, Inc. (NASDAQ: TGTX), today announced preclinical data presentation for TG-1701, the Company’s highly selective, BTK inhibitor, at the 2020 American Association for Cancer Research (AACR) annual meeting, being held virtually.\n Michael S. Weiss, the Company’s Executive Chairman and Chief Executive Officer stated, “We are encouraged by the preclinical data presented today which showed TG-1701 to be just as active and more selective for BTK than ibrutinib, a currently approved BTK inhibitor. Importantly, we are pleased to see the additive anti-tumor inhibition seen when TG-1701 was combined with umbralisib plus ublituximab (U2), supporting our combinatorial approach to development. The proprietary triple combination regimen of U2 + TG-1701 has shown strong responses clinically in an ongoing Phase 1 study, and we look forward to continuing this research and presenting updated data on TG-1701 as a monotherapy and as a triple regimen with U2.” Highlights from the data presentation are included below. Title: TG-1701, a novel irreversible Bruton’s kinase (BTK) inhibitor, does not inhibit anti-CD20-driven ADCC and ADCP in vitro, and cooperates with the glycoengineered anti-CD20 mAb, ublituximab, in in vivo mantle cell lymphoma models In vitro and in vivo studies were undertaken to evaluate the activity of TG-1701 alone and in combination with ublituximab and umbralisib in models of lymphomaTG-1701 showed greater selectivity for BTK than, and similar activity to, ibrutinib in mantel cell lymphoma (MCL) modelsTG-1701, in contrast to ibrutinib, did not block ublituximab-driven antibody-dependent cellular cytotoxicity (ADCC) or antibody-dependent cell phagocytosis (ADCP) in vitroIn vivo xenograft studies suggested that TG-1701 synergized with the U2 combination, resulting in greater anti-tumor activity than either TG-1701 or U2 alone The above data presentation is available on the Publications page of the Company’s website at www.tgtherapeutics.com/publications.cfm.
