In Brief

A Phase 1 clinical trial evaluating Pembrolizumab Dose C, Pembrolizumab Dose A, and 2 other interventions for Melanoma. Completed, enrolled 138 participants across 15 sites in 4 countries.

Detailed Summary

The purpose of this study is to characterize the pharmacokinetic (PK) profile of pembrolizumab (MK-3475) following single subcutaneous (SC) injection of pembrolizumab Dose A versus pembrolizumab Dose C in adults with advanced melanoma. Additionally, the safety and tolerability of pembrolizumab SC injections will be assessed. And, finally, the efficacy of pembrolizumab intravenous (IV) infusion administration will be assessed.
