A Study of IBI129 in Subjects With Unresectable, Locally Advanced or Metastatic Solid Tumors
Study Details
Study Description
Brief Summary
This is a phase 1/2 multicenter, first-in-human study of IBI129. It includes a phase 1 dose escalation and expansion section to identify MTD/RP2D of IBI129, plan to enroll 22~180 subjects, and a phase 2 to explore efficacy, safety and tolerability of IBI129 at RP2D in specified types of solid tumor. Approximately 182 evaluable subjects will be enrolled for phase 2

| Experimental: IBI129 IBI129 |
Drug: IBI129
Subjects will receive IBI129 on Day 1 of a 21-day cycle (or intervals determined by the Investigator and Sponsor based on safety, toxicity and PK data), until unacceptable toxicity, disease progression, withdrawal of consent, occurrence of other reasons for discontinuing study therapy, or for a maximum of 24 months of treatment, whichever occurs first.
