New antibody combo targets Hard-to-Treat cancers

NCT ID NCT05753722

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

Summary

This early-stage trial is testing a new drug called PRTH-101, alone or with an existing immunotherapy (pembrolizumab), in adults with advanced or metastatic solid tumors that have not responded to standard treatments. The study will enroll about 270 people and focus on safety, dosing, and how the drug moves through the body. It is not yet known if PRTH-101 will shrink tumors or improve survival.

What this could mean

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

Active substance

PRTH-101 (a lab-made antibody) and pembrolizumab (an immunotherapy drug)

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, so the main goal is safety, not effectiveness. The drug may not work or could cause serious side effects. Only a small number of people will be tested.
