Ascentage Pharma Group International is a clinical-stage biopharmaceutical firm dedicated to discovering and developing innovative therapies for various cancers, chronic hepatitis B virus (HBV), and age-related conditions. Its operations are concentrated across the United States and Mainland China. Ascentage Pharma's flagship therapeutic candidate, HQP1351 (Olverembatinib), is a BCR-ABL inhibitor specifically designed to target BCR-ABL mutants, including those carrying the T315I mutation. This compound is intended for patients suffering from chronic phase chronic myeloid leukemia that has become resistant to tyrosine kinase inhibitors. Beyond HQP1351, the company boasts a robust pipeline. This includes APG-2575 (Pelcitoclax), an orally administered, selective Bcl-2 inhibitor undergoing Phase Ib/II clinical studies for hematologic and solid tumors; APG-115 (Alrizomadlin), an oral small molecule designed to inhibit the MDM2-p53 protein-protein interaction for various solid and hematological malignancies; and APG-1387 (Nevadotinib), a small molecule inhibitor of apoptosis proteins targeting advanced solid tumors and chronic HBV infections. Further advancing its portfolio, Ascentage is developing APG-1252 (Atoloclab), a small molecule drug aimed at restoring apoptosis by selectively inhibiting Bcl-2 and Bcl-xL proteins for conditions such as small cell lung cancer (SCLC), lymphoma, and other solid tumors. The pipeline also features APG-2449 (Glecirasib) for non-small-cell lung carcinoma (NSCLC); APG-5918, an orally available and selective EED inhibitor with best-in-class potential in its preclinical phase; APG-265, currently in IND-enabling stages for hematological and solid tumors; and UBX1967/1325, a Phase II candidate targeting the Bcl family for diabetic macular edema (DME). The company maintains strategic collaboration agreements with prominent biotechnology and pharmaceutical companies, as well as academic institutions. Key partners include Innovent Biologics, Inc., the National Cancer Institute, Pfizer Inc., and Clover Biopharmaceuticals (Hong Kong) Co., Limited.
