“This study was designed to evaluate a coformulation of vibostolimab and pembrolizumab in a population of patients who are heavily pre-treated and have progressed following treatment with standard of care therapies, often leaving them with limited treatment options and a poor prognosis,” said Dr. Scot Ebbinghaus, vice president, global clinical development, Merck Research Laboratories. “We will leverage our evolving understanding of novel combinations and coformulations to help inform our comprehensive research program evaluating this coformulation across a wide range of tumor types.”
