Experimental tumor injection trial halted early

NCT ID NCT03871348

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

Summary

This early-stage trial tested an experimental drug called SAR441000, injected directly into tumors, either alone or with another drug (cemiplimab) given through a vein. The study aimed to find a safe dose and see if the combination could shrink tumors in people with advanced solid cancers like melanoma. However, the trial was terminated early, so full results are not available.

What this could mean

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

Active substance

SAR441000 (injected into tumors) and cemiplimab (given intravenously)

What this could lead to

If it works, this could point toward a new treatment option for people with advanced solid tumors that have not responded to other therapies.

What could go wrong

This is a very early (Phase 1) trial that was terminated, so results are limited. The approach is experimental and may not prove safe or effective.
