Summary

This phase 2 trial is testing whether combining the immunotherapy drug tislelizumab with other experimental drugs (surzebiclimab or alcestobart) can shrink tumors or slow cancer growth in people with advanced head and neck cancer that has come back or spread. About 160 participants who have not had prior treatment for their advanced cancer will receive one of the combinations. The study measures how many patients respond and how long the response lasts.

What this could mean

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

Active substance
Tislelizumab (immunotherapy) combined with surzebiclimab or alcestobart
What this could lead to
If successful, this could lead to a new first-line treatment option that shrinks tumors or delays cancer growth in people with advanced head and neck cancer.
What could go wrong
This is an early-phase trial with only 160 participants, so results may not apply to everyone. The drug combinations may cause side effects like immune-related inflammation, and there is no guarantee of benefit.
