Head and neck squamous cell carcinoma (HNSCC) is the 6th most common cancer worldwide. These cancers have different causes, with smoking/tobacco exposure and human papilloma virus infection being the most common. . When HNSCC occurs in people who are not infected with HPV, the cancers are more likely to return after treatment; when this happens, overall survival is only about 10 months, thus better treatments are needed.
Objective:
To test a combination treatment using 2 drugs (valemetostat and pembrolizumab) in people with HNSCC. Phase 1b of the study will determine a recommended dose of the 2 drugs and evaluate how safe the combination is.; this will include patients with HPV-positive and HPV-negative HNSCC, as well as squamous cell NSCLC that have progressed on anti-PD-1/anti-PD-L1 therapies.Phase II will determine how effective the combination is and will focus on patients with HPV-negative HNSCC.
Eligibility:
People aged 18 years and older with HPV-negative HNSCC, sinonasal carcinoma of the head and neck, or squamous non-small cell lung cancer (NSCLC).
Design:
Participants will be screened. They will have a physical exam. They will have blood and urine tests and tests of their heart function. They will have imaging scans. They may have a biopsy: A small sample of tissue will be removed from the tumor.
Treatment will be given in 21-day cycles.
Pembrolizumab is administered through a tube attached to a needle inserted into a vein in the arm. Participants will receive pembrolizumab on the first day of each cycle.
Valemetostat is a tablet taken by mouth. Participants will take the tablet once a day at home. They will record the date and time of each dose in a diary. They will also write down any adverse effects they experience.
Participants may remain in the study up to 2 years.
