Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, for the treatment of patients with Merkel Cell Carcinoma (MCC) who have failed treatment with at least one anti-PD-1 or anti-PD-L1 immunotherapy or in combination with avelumab in MCC patients who are anti-PD-1 or anti-PD-L1 treatment naïve. Inhibition of MDM2 is a novel mechanism of action in MCC.
