Experimental combo shows promise for Hard-to-Treat melanoma

NCT ID NCT04570332

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tested a combination of two drugs—BO-112, injected directly into tumors, and pembrolizumab, given through a vein—in 42 adults with advanced melanoma that had stopped responding to standard immunotherapy. The goal was to see if the combo could shrink tumors and be safe. Participants had stage III or IV melanoma and had already progressed on anti-PD-1 therapy.

What this could mean

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

Active substance

BO-112 (injected into tumors) plus pembrolizumab (given intravenously)

What this could lead to

If successful, this combination could offer a new treatment option for advanced melanoma patients whose cancer stopped responding to standard immunotherapy.

What could go wrong

This is a small, early-phase trial with only 42 participants and no comparison group, so results may not apply broadly. The treatment involves injections into tumors and carries risks like injection site reactions and immune-related side effects.
