First-in-Human Trial of VBC108 in Participants With Advanced Malignant Solid Tumors

Starting soon · Phase 1/Phase 2

Conditions studied: Advanced Solid Tumors

In brief

This is a multicenter, open-label, multiple-dose, FIH Phase 1/2a trial. The Phase 1 portion uses Bayesian optimal interval (BOIN) design to escalate and determine the MTD and/or RP2D with potential backfill cohorts. The Phase 2a portion consists of dose optimization followed by cohort expansion to confirm safety and tolerability and to further evaluate the efficacy of the selected RP2D in selected solid tumor malignancies for VBC108.
