Gastric/gastroesophageal junction (G/GEJ) cancer is one of the most common cancers and approximately 20% of these patients show HER2 amplification or overexpression. Despite the approval of Herceptin® (trastuzumab) in the US in 2010, the median overall survival of patients suffering from HER2+ gastric cancer remains limited. HLX22 (AC101) is an innovative monoclonal anti-HER2-antibody, which was out-licensed by Alligator to the South Korean company AbClon, Inc. in 2016, who sub-licensed the drug candidate to Henlius Biotech for clinical and commercial development in China. Alligator retains an ownership interest entitling the company to 35% of AbClon's income from the agreement with Henlius Biotech. In January 2024, Henlius Biotech presented promising Phase 2 results at the 2024 ASCO Gastrointestinal Cancers Symposium (ASCO GI), which were also published in the Journal of Clinical Oncology. The data demonstrated that the addition of HLX22 (AC101) to HLX02 (a biosimilar of trastuzumab) and XELOX (Oxaliplatin and capecitabin) in 1st line treatment of HER2-positive locally advanced or metastatic G/GEJ cancer led to a dose-dependent increase in Progression Free Survival, meeting the study's main efficacy endpoint. "We are very pleased to see the highly encouraging progress Henlius Biotech are making with the development of HLX22 in gastric cancer," said Søren Bregenholt, CEO of Alligator Bioscience."The Phase 2 results presented at ASCO earlier this year followed by this Phase 3 IND clearance demonstrate our ability to deliver an asset like HLX22 with a highly differentiated profile and a great deal of potential to improve treatment outcomes for patients suffering from a devastating disease like gastric cancer."
