NCT ID NCT07612488

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

Summary

This early-stage trial tests a new drug called CS231295 in 42 adults with advanced solid tumors that have stopped responding to standard treatments. The drug works by blocking certain proteins that help tumors grow and form blood vessels. The main goals are to check safety, find the right dose, and see early signs of whether the drug 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

CS231295 (a targeted drug that blocks proteins involved in tumor growth and blood vessel formation)

What this could lead to

If this drug is safe and shows signs of shrinking tumors, it could lead to a new treatment option for people with advanced solid cancers that no longer respond to standard therapies.

What could go wrong

This is a very early (Phase 1) trial with only 42 people, focused mainly on safety and dosing. It is too soon to know if the drug will work, and side effects are unknown.
