NCT ID NCT04879849

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This early-phase trial tested an experimental drug called TAK-676 combined with the immunotherapy pembrolizumab after radiation therapy in 34 adults with advanced lung, breast, or head/neck cancers that had stopped responding to checkpoint inhibitors. The main goals were to check safety, side effects, and find the best dose of TAK-676. Participants received radiation first, then the drug combo every three weeks.

What this could mean

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

Active substance

TAK-676 (an experimental drug) combined with pembrolizumab (an immunotherapy) after radiation therapy

What this could lead to

If successful, this could point toward a new treatment option for people with certain advanced cancers that have stopped responding to standard immunotherapy.

What could go wrong

This is a very early, small Phase 1 study focused on safety and dosing, not effectiveness. The combination may cause significant side effects and may not shrink tumors.
