Summary

This early-stage trial tested a new drug, PF-07820435, alone or with another immunotherapy (sasanlimab) in 9 people with advanced solid tumors like lung, skin, or kidney cancer. The main goals were to check safety and find the right dose. The study was terminated early, so results are limited.

Active substance

What this could lead to
If it works, this could point toward a new treatment option for advanced solid tumors like lung or skin cancer.
What could go wrong
