CSPC Pharmaceutical (HKG:1093) said Corbus Pharmaceuticals has received U.S. FDA clearance to begin a registrational trial of CRB-701 (SYS6002), which it is developing under license from CSPC, for second-line treatment of oropharyngeal squamous cell carcinoma.
The TEMPO-1 study will evaluate the antibody-drug conjugate against the investigator's choice of capecitabine, cetuximab, or docetaxel, with objective response rate and overall survival as the primary endpoints, according to a Wednesday filing with the Hong Kong bourse.
Corbus expects to begin patient enrollment in the third quarter of 2026.
