Cancer cocktail trial halted early – what went wrong?

NCT ID NCT02959437

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a combination of three drugs (azacitidine, pembrolizumab, and epacadostat) in 70 people with advanced solid tumors, including lung and colorectal cancers. The goal was to see if the combination was safe and could shrink tumors. However, the trial was terminated early, meaning the results are incomplete and no clear conclusions can be drawn about its effectiveness.

What this could lead to

If successful, this combination might offer a new treatment option for people with advanced solid tumors that have not responded to standard therapies.
