On September 14, INNOCARE rose 8.12% in regular trading, trading at HKD 14.64/share, with turnover of approximately HKD 39.6 million. The rally was driven by the announcement that the company's independently developed dual-antibody ADC drug ICP-B381, targeting PSMA and STEAP1, received approval from China's National Medical Products Administration to commence clinical trials for the treatment of prostate cancer and other solid tumors.
ICP-B381 is the first dual-antibody ADC developed on INNOCARE's proprietary ADC platform, composed of a humanized anti-PSMA/STEAP1 antibody conjugated with the company's next-generation irreversible linker and a potent payload. Notably, at equivalent dosing levels, ICP-B381 demonstrated superior efficacy compared to corresponding single-target PSMA ADC and STEAP1 ADC candidates, while maintaining a favorable tolerability profile. Currently, no dual-antibody ADC targeting both PSMA and STEAP1 has been approved globally, positioning ICP-B381 as a potentially first-in-class therapy.
The broader Hong Kong-listed biotechnology sector also traded higher during the session, with AKESO up 5.09%, 3SBIO up 3.82%, INNOVENT BIO up 1.66%, BEONE MEDICINES up 1.55%, and IMPACT THERAP-B up 1.55%.
