Navtemadlin (KRT-232) With or Without Anti-PD-1/Anti-PD-L1 for the Treatment of Patients With Merkel Cell Carcinoma

Study Purpose

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.

Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
