TG Therapeutics Presents Preclinical Data for TG-1801, a First-in-Class Anti-CD47/CD19 Bispecific Antibody, at the 24th European Hematology Association Annual Congress
Jun 17, 2019
Highlights from this poster presentation include:
- TG-1801 is a first-in-class anti-CD47-CD19 bispecific antibody that selectively targets CD47 on CD19+ B-cells, sparing red blood cells and platelets, and blocking the CD47-SIRPα macrophage checkpoint on mature B cells
- Ublituximab exerts stronger ADCP and ADCC activity in B-
NHLcells when compared to rituximab, and TG-1801 increased the ADCC and ADCP activities initiated by both ublituximab and the U2 combination
- The triple combination of TG-1801 + U2 was found to regulate genes related to cell architecture
- TG-1801 triggers synergistic tumor growth inhibition and results in prolonged remission when added to U2 in an in vivo Raji lymphoma model, which appears to be mediated by increased infiltration of immune effector cells

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 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 into Phase 1 clinical development, TG-1501, its anti-PD-L1 monoclonal antibody, TG-1701, its covalently-bound Bruton’s Tyrosine Kinase (BTK) inhibitor and TG-1801, its anti-CD47/CD19 bispecific antibody. TG Therapeutics is headquartered in New York City.
