Summary

This Phase 2 trial is testing tislelizumab, an immunotherapy drug, in 200 people with advanced solid tumors that have specific genetic changes (MSI-H or dMMR) and have not responded to prior treatments. The drug works by blocking PD-1, helping the immune system recognize and attack cancer cells. The main goal is to see how many patients' tumors shrink or disappear.

What this could mean

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

Active substance
tislelizumab (an immunotherapy drug that helps the immune system attack cancer cells)
What this could lead to
If successful, this could offer a new treatment option for people with advanced cancers that have specific genetic features (MSI-H or dMMR) and have not responded to prior therapies.
What could go wrong
This is a mid-stage (Phase 2) trial with no control group, so results are preliminary. The drug may not work for all tumor types, and side effects from immune activation (e.g., inflammation of organs) are possible.
