A First-in-human Study of IBI354 in Subjects with Locally Advanced Unresectable or Metastatic Solid Tumors

Recruiting now · Phase 1/Phase 2

Conditions studied: Locally Advanced Unresectable or Metastatic Solid Tumors

In brief

This is a Phase 1/2, open-label, multicenter study designed to evaluate the safety, tolerability, and DLTs to establish the maximum tolerated dose (MTD) or maximum administered dose (MAD), and the RP2D of sequential doses of IBI354 (study drug), and to explore and confirm the efficacy, safety and tolerability of IBI354 in subjects with locally advanced unresectable or metastatic solid tumors.
