First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase II trial tested the drug abemaciclib in 7 people with HPV-negative head and neck cancer. Participants took the drug for 10 to 28 days before their planned surgery. The goal was to see if the drug could shrink tumors and to check for side effects. The study was terminated early, so the findings are limited.
