Pfizer Licenses CD228-Targeting ADC to Medicus Pharma in Co-Development Deal

Akeso has secured Phase I clinical trial clearance in China for AK158D1, a bispecific antibody drug conjugate targeting EGFR and TROP2 in advanced solid tumors. The clearance puts fresh attention on the company's pipeline as it pushes deeper into IO2.0 and ADC2.0. Akeso's shares recently traded at HK$90.5, up 3.37% over 90 days but down 20.12% year to date, against a consensus analyst price target of HK$158.28, with the most bullish target at HK$226.04 and the most bearish at HK$125.08. The company remains exposed to execution setbacks given its reliance on a handful of key drugs and a current net loss of CN¥967.2 million.

Merck received a positive opinion from the European Medicines Agency's CHMP for KEYTRUDA plus Padcev in muscle-invasive bladder cancer. The CHMP backed the combination as perioperative therapy for adults with resectable muscle-invasive bladder cancer in the European Union. If endorsed by the European Commission, the regimen would be the first PD-1 inhibitor plus antibody-drug conjugate option for this setting in Europe. The addressable group in Europe is relatively concentrated but clinically high need, with bladder cancer cases estimated at about 224,700 in 2022, roughly 25% of them classified as muscle invasive. The key near-term marker is the European Commission ruling expected by the fourth quarter of 2026, since the CHMP only issues recommendations.
