ClinConnect Summary

This clinical trial is investigating a new treatment approach for patients with locally advanced squamous cell carcinoma of the head and neck, a type of cancer that can be challenging to treat, especially when it has not spread to other parts of the body. The study is looking at the combination of three treatments: palbociclib, which is a medication that helps stop cancer cells from growing; cetuximab, which targets cancer cells; and intensity-modulated radiation therapy (IMRT), a type of radiation treatment. The goal is to determine the safest dose of these medications and see how well they work together.

To be eligible for this trial, participants must be at least 18 years old and have a confirmed diagnosis of locally advanced squamous cell carcinoma in areas like the oral cavity or throat. They should be able to provide tissue samples to check for specific cancer-related markers and must meet certain health criteria, such as having good organ function and no recent significant weight loss. Participants can expect close monitoring during the trial to manage any side effects and to ensure their safety. This trial is a promising opportunity for patients seeking new treatment options for head and neck cancer.
