Experimental cancer drug enters human testing

NCT ID NCT06431594

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

Summary

This early-stage trial tests an experimental drug called mocertatug rezetecan in 675 adults with advanced solid tumors that have not responded to standard treatments. The drug is designed to deliver a toxin directly to cancer cells. The main goals are to check safety, find the right dose, and see if tumors shrink.

What this could mean

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

Active substance

mocertatug rezetecan (an experimental antibody-drug conjugate that delivers a toxin to cancer cells)

What this could lead to

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

What could go wrong

This is an early Phase 1 trial focused on safety and dosing, so it is too soon to know if the drug will work. Side effects from the toxin or antibody may limit its use.
