Summary

This trial will test whether using pembrolizumab and olaparib together before and after chemoradiation therapy is more effective in treating locally advanced head and neck squamous cell carcinoma than chemoradiation therapy alone.

Who is the study for?
This trial is for adults over 18 with certain types of head and neck squamous cell carcinoma (HNSCC) that haven't been treated yet. Participants need to be in good physical condition, able to follow the study plan, and have a tumor assessable by imaging. They can't join if they've had other cancer treatments recently, can't swallow pills, are ineligible for cisplatin therapy, or have severe medical issues.
What is being tested?
The trial tests pembrolizumab plus olaparib before and after standard chemoradiation therapy for advanced HNSCC. These drugs are approved separately but not together; this study examines their combined effectiveness when paired with chemo and radiation.
What are the potential side effects?
Pembrolizumab may cause immune system-related side effects like inflammation in organs or skin reactions. Olaparib could lead to blood cell count changes, nausea, fatigue or respiratory issues. Cisplatin might result in kidney problems, hearing loss or nerve damage.
