New antibody drug takes on advanced cancers in first human trial

NCT ID NCT05378425

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial is testing a new drug called NTX-1088, which targets a protein on cancer cells, either alone or combined with the immunotherapy pembrolizumab. The study involves 90 people with advanced solid tumors that have spread or cannot be removed. The main goals are to find a safe dose and to see if the treatment can shrink tumors.

What this could mean

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

Active substance

NTX-1088 (a lab-made antibody targeting a protein on cancer cells) and pembrolizumab (an immunotherapy drug that helps the immune system attack cancer)

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) and small study, so the drug may not shrink tumors or could cause side effects. Success in this trial does not guarantee it will work for most patients.
