New pill targets Hard-to-Treat cancers with rare TP53 mutation
NCT ID NCT07060989
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests an experimental oral drug called NTS071 in adults with advanced solid tumors that have a specific change in the TP53 gene (Y220C mutation). The trial has two parts: first, finding a safe dose, and then checking if the drug can shrink tumors. About 220 people who have already tried other cancer treatments will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- NTS071 (oral drug)
- What this could lead to
- If successful, this could point toward a new treatment option for people with advanced solid tumors that have a specific TP53 mutation.
- What could go wrong
- This is an early-phase trial (Phase 1/2a) with a small number of participants, so the drug may not prove effective or safe enough for wider use. Side effects are still being studied.
