Summary

This phase 2 trial tests whether giving targeted radiation along with two immunotherapy drugs (evorpacept and pembrolizumab) before standard surgery can improve outcomes for people with HPV-related throat cancer. The study enrolls 29 patients with early-stage, resectable disease. The main goal is to see if the cancer responds completely or mostly to this pre-surgery treatment.

What this could mean

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

Active substance
evorpacept (ALX148) and pembrolizumab
What this could lead to
If successful, this approach could improve how well HPV-related throat cancer responds to treatment before surgery, potentially leading to better outcomes.
What could go wrong
This is a small, early-phase trial with only 29 participants. The combination may not improve response rates and could cause side effects from radiation and immunotherapy.
