Decitabine and Nivolumab in Participants With Recurrent/Metastatic Squamous Cell Carcinoma of the Head and Neck

Plain-language summary
This research study is for people who have recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) that has been confirmed by tissue or cell analysis and is considered incurable with local treatments. People who are eligible to receive anti-PD-L1 therapy as a first line treatment and whose primary tumor is located in the oral cavity, oropharynx, hypopharynx, or larynx, may be eligible to participate.
The purpose of this study is to evaluate the immunogenicity of decitabine in combination with nivolumab, and to evaluate the safety and tolerability of decitabine in combination with nivolumab and to determine the maximum tolerated dose.
Decitabine is a drug that is currently approved by the Food and Drug Administration (FDA) for the treatment of myelodysplastic syndrome (MDS). Decitabine is considered an investigational (experimental) drug in this study because it is not approved by the FDA for the treatment of HNSCC. Decitabine is a chemotherapy drug that works by targeting DNA methylation, a process that can restore normal function to genes that are involved in cell growth and differentiation. This can help reduce the growth of cancer cells.
Nivolumab is a drug that is approved by the FDA for the treatment of HNSCC, as well as other types of cancer. Nivolumab is an immunotherapy drug that works by helping the body's immune system recognize and attack cancer cells.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Participants must have histologically or cytologically confirmed recurrent or metastatic HNSCC considered incurable by local therapies and eligible to receive anti-PD-L1 as first-line treatment (PD-L1 positive with combined positive score (CPS) 1 as evaluated in pre-screening).
* Participants must have primary tumor locations in following; oral cavity, oropharynx, hypopharynx, or larynx (nasopharynx is not allowed).
* No systemic therapy administered in the recurrent or metastatic setting (except for systemic therapy completed within 6 months or \> 6 months if given as part of multimodal treatment for locally advanced disease).
* Participants must not have received prior treatment with immune checkpoint inhibitors.
* For primary site locally recurrent HNSCC, participants can provide archival tumor tissue not older than 3 months from a core or excisional biopsy for PD-L1 pre-screening using the PD-L1 IHC 22C3 pharmDx assay.
* For metastatic cancer patients, archival tumor tissue of distant metastatic lesion should not be older than 3 months from a core biopsy for PD-L1 pre-screening using the PD-L1 IHC 22C3 pharmDx assay.
* For primary site locally recurrent HNSCC, participants must have lesions amenable to obtain pre-treatment tumor biopsies in screening period after eligibility confirmation and before start of treatment and on-treatment tumor biopsies on C1D8 \& C3D21 after start of treatment if lesions are still present at that time.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
