Poster Presentations to highlight the latest research on OBI-999’s (anti-Globo H ADC) synergistic anti-tumor effect in combination with pembrolizumab and OBI’s development of CAR T-cell cancer immunotherapy targeting Globo H.

TAIPEI, Taiwan, April 10, 2023 (GLOBE NEWSWIRE) -- OBI Pharma, Inc. (TPEx: 4174) today announced preclinical data demonstrating significant synergistic effects of OBI-999 and pembrolizumab (anti-PD1 mAb) in four different cancer models, as well as the potent antitumor effect of a chimeric antigen receptor T-cell (CAR T) immunotherapy targeting Globo H. These data will be presented at the American Association of Cancer Research (AACR) Annual Meeting from 14th-19th April, 2023 in Orlando, Florida (USA).

OBI’s Chief Scientific Officer Ming-Tain Lai, Ph.D., commented that “Our scientific data suggest OBI-999 creates a tumor microenvironment that can significantly enhance the function of pembrolizumab. This potentiated anti-tumor effect was evident in four different xenograft models (breast, gastric, colorectal, and small cell lung cancer) that expressed Globo H and PD-1. These findings support the clinical study of combination therapeutic strategies that pair OBI-999 with anti PD-1/PD-L1 cancer therapeutics. OBI has also developed the first CAR T-cell therapy (OBI-R007) targeting Globo H, which demonstrates a strong and specific anti-tumor effect on Globo H-expressing tumor cells. These encouraging results warrant further development of this novel cellular therapy.”
