Summary

This early-phase study tested whether adding two drugs (romidepsin and 5-azacitidine) to an immunotherapy (MK-3475) could help people with a specific type of advanced colorectal cancer called microsatellite stable (MSS). The study included 27 adults whose cancer had already spread and who had tried at least one prior treatment. The main goals were to check safety and see if the combination could increase immune cells in tumors.
