Combination therapy study for advanced solid tumors
This trial is testing two new drugs (DB-1311 with BNT327 or DB-1305) in people with certain advanced or metastatic solid tumors that have not responded to prior treatments. It aims to see if the combination shrinks tumors or slows cancer growth.
Los Angeles, CaliforniaAges 18 years+ - NCT06953193Recruiting
