Experimental kidney cancer drug trial halted early

NCT ID NCT04895748

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

Summary

This early-stage trial tested a new drug called DFF332, which targets a protein (HIF2α) that helps some cancers grow. The study included 40 adults with advanced clear cell renal cell carcinoma or other cancers with specific gene changes. DFF332 was tested alone and in combination with other drugs, but the trial was terminated early, so we have limited information on its safety or effectiveness.

What this could mean

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

Active substance

DFF332 (a drug that targets HIF2α protein)

What this could lead to

If it worked, DFF332 might offer a new way to slow or stop certain kidney cancers by blocking a protein that helps tumors grow.

What could go wrong

This was a very early (phase 1) trial that was terminated, meaning it was stopped before completion. It involved only 40 people, so any benefits or risks are not well understood.
