Summary

This study tested combinations of three immunotherapy drugs—tislelizumab, surzebiclimab, and alcestobart—in 147 adults with advanced solid tumors that had not responded to prior treatments. The goal was to find safe doses and see if the drugs could shrink tumors. The trial is now complete, and results will help guide future research on these combinations.

What this could mean

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

Active substance
tislelizumab, surzebiclimab, and alcestobart (three immunotherapy drugs that help the immune system attack cancer)
What this could lead to
If successful, this combination could offer a new treatment option for people with advanced solid tumors that have not responded to standard therapies.
What could go wrong
This is an early-phase trial (Phase 1/2) with a small number of participants, so results may not apply to all patients. Side effects from immunotherapy can be serious, including immune-related inflammation in healthy organs.
