A Study to Evaluate the Safety of INCA33890 in Participants With Advanced or Metastatic Solid Tumors

A Phase 1, Open-Label, Multicenter Study of INCA33890 in Participants With Advanced or Metastatic Solid Tumors

To evaluate the safety, tolerability, and DLTs and determine the MTD and/or RDE(s) of INCA33890 in participants with select advanced or metastatic solid tumors.

• Part 1: Participants must have experienced disease progression after treatment with, be intolerant to, or be ineligible for, or refused available therapies, including anti-PD-(L)1 or anti-CTLA4 therapy if applicable, that are known to confer clinical benefit. Part 2: depending on cohort, participants may have received or not prior treatment for the malignancy under study.
• ECOG performance status score of 0 or 1.
• Willingness to undergo pre- and on-treatment tumor biopsy (core or excisional). Biopsies are mandatory depending on the cohorts.
