New drug combo aims to boost immune attack on HPV throat cancer before surgery
NCT ID NCT05787639
First seen Jun 26, 2026 · Last updated Jul 17, 2026 · Updated 3 times
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.
