New drug AMT-253 enters human trials for Tough-to-Treat cancers
NCT ID NCT06209580
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This early-stage trial is testing an experimental drug called AMT-253 in about 96 people with advanced melanoma or other solid tumors that have not responded to standard treatments. The study has two parts: first, finding the safest dose, and then expanding to see how well the drug works. The main goals are to check safety and measure tumor shrinkage.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AMT-253 (an experimental drug given by IV)
- What this could lead to
- If successful, this could point toward a new treatment option for people with advanced melanoma or other solid tumors that have stopped responding to standard therapies.
- What could go wrong
- This is a very early, small study (96 people) focused mainly on safety and dosing. The drug may not shrink tumors or could cause serious side effects. Success in early phases does not guarantee later approval.

WCBP must have a negative serum pregnancy test within 7 days prior to first dose of the IMP. * 10\.
