Summary

This early-phase study tests a new drug (PLN-101095) alone or with pembrolizumab in adults whose advanced solid tumors have stopped responding to standard immunotherapy. About 124 participants will receive the treatment to check safety and early signs of tumor shrinkage. The goal is to find a safe dose and see if the combination can re-sensitize tumors to immunotherapy.
