4SC-202 in Combination With Pembrolizumab in Patients Primary Refractory/Non-responding to Prior Anti-PD-1 Therapy

Study Purpose

Phase Ib/II open-label, multi-center study with a priming cycle of 4SC-202 to evaluate the safety, tolerability and preliminary efficacy of combination treatment with 4SC-202 and Pembrolizumab. A dose expansion cohort at the Recommended Phase Two Dose (RPTD) will be added. Adult patients with advanced (unresectable or metastatic) cutaneous melanoma primary refractory or non-responding to anti-PD-1 therapy as most current systemic anti-cancer therapy and for whom no standard therapy is available, will be enrolled. The last administration of anti-PD-1 therapy must have been performed within 6 months prior to screening.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


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.
