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

Summary

This early-phase study tests an experimental drug called OKN4395, taken as a pill, alone or together with the immunotherapy pembrolizumab. The goal is to find a safe dose and see if the combination can shrink tumors in people with advanced solid cancers like lung, colorectal, stomach, or sarcoma. About 146 participants will take part across the US, Australia, UK, and EU.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

OKN4395 (an experimental drug) and pembrolizumab (an immunotherapy)

What this could lead to

If successful, this could point toward a new treatment option for advanced solid tumors that have stopped responding to standard therapies.

What could go wrong

This is an early Phase 1 trial with a small number of participants, so safety and effectiveness are not yet established. The drug may cause side effects or fail to shrink tumors.
