TG Therapeutics Announces Preclinical Data Presentation at the 2020 American Association for Cancer Research Annual Meeting
Jun 22, 2020
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 lymphoma
- TG-1701 showed greater selectivity for BTK than, and similar activity to, ibrutinib in mantel cell lymphoma (MCL) models
- TG-1701, in contrast to ibrutinib, did not block ublituximab-driven antibody-dependent cellular cytotoxicity (ADCC) or antibody-dependent cell phagocytosis (ADCP) in vitro
- In 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.
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 multiple 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 dual inhibitor of PI3K-delta and CK1-epsilon, which may lead to a differentiated safety profile. 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 into Phase 1 clinical development its anti-PD-L1 monoclonal antibody, cosibelimab (TG-1501), its covalently-bound Bruton’s Tyrosine Kinase (BTK) inhibitor, TG-1701, as well as its anti-CD47/CD19 bispecific antibody, TG-1801. TG Therapeutics is headquartered in New York City.
