First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This early-phase trial tests a new treatment for people with advanced melanoma that has stopped responding to standard immunotherapy. The treatment uses a patient's own immune cells (TILs) that have been engineered to produce a protein called IL15, combined with a drug called acetazolamide. The study aims to find the safest dose and check for side effects in about 21 adults.

What this could mean

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

Active substance

OBX-115 (engineered immune cells) and acetazolamide

What this could lead to

If it works, this could point toward a new treatment option for people with advanced melanoma that hasn't responded to standard immunotherapy.

What could go wrong

This is an early, small Phase 1 trial with only 21 participants, so it's mainly checking safety and dosing. The treatment may not shrink tumors or could cause serious side effects.
