New immunotherapy cocktail takes on head and neck cancer
NCT ID NCT05909904
First seen Jun 27, 2026 · Last updated Sep 02, 2026 · Updated 4 times
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.
