About this trial
This is a multicenter, open-label, multiple-dose, FIH Phase 1a/1b study. Phase 1a adopts an accelerated titration design and a BOIN design to identify the MTD or MAD of DB-1317; Phase 1b includes up to 3 randomized dose expansion cohorts to further evaluate the safety, tolerability and preliminary efficacy of DB-1317 in selected solid tumors and to identify optimal RP2D.
