OBI Pharma Announces Poster Presentations at AACR 2022 Annual Meeting for OBI-3424 and Globo H Science

Poster Presentations to highlight the latest research on OBI-3424 (AKR1C3 small molecule  pro-drug) and emerging Globo H science.

OBI Pharma, Inc. (TPEx: 4174) today announced scientific data highlighting the antitumor synergy of OBI-3424 in combination with pembrolizumab (PD-1) and the association of high Globo H and PD-L1 expression resulting in poor survival in gastric cancer patients, will be presented at the American Association of Cancer Research (AACR) Annual Meeting from April 8–13, 2022 in New Orleans, LA. (USA).

OBI’s Chief Scientific Officer, Ming-Tain Lai, Ph. D stated that “OBI Pharma is proud to present at the AACR Annual Meeting our latest scientific findings on the efficacy of OBI-3424 and the role of the Globo H antigen. OBI-3424 can induce immunogenic cell death and demonstrated impressive synergistic efficacy in combination with Pembrolizumab in various cancer models. Emerging science also demonstrated poor survival in gastric cancer patients who have high Globo H and PD-L1 expression. These findings warrant potential combination therapeutic strategies of OBI-3424 as well as anti-Globo H plus PD-1/PD-L1 cancer therapeutics ”.
