ClinConnect Summary
This clinical trial is looking at a new treatment approach for patients with locally advanced head and neck squamous cell carcinoma (HNSCC), which is a type of cancer that affects areas like the throat and mouth. The study is testing a combination of a drug called pucotenlimab and standard chemotherapy (cisplatin and docetaxel) to see if this treatment can help shrink the tumor before surgery. Participants will receive three cycles of this treatment before undergoing standard surgical procedures, and the researchers will evaluate how well the treatment works and its safety.
To be eligible for the trial, participants need to be between 18 and 70 years old, have a confirmed diagnosis of stage III or IV HNSCC, and have not received any previous treatment for their cancer. They should also have measurable tumors and be in good overall health, meaning they can carry out daily activities without major issues. Participants can expect regular check-ups during the treatment and surgery afterward, followed by monitoring for any signs of cancer returning. It's important to note that this trial is not yet recruiting participants, so those interested will need to wait until it begins.
