About this trial

This study is being done because both 5-azacytidine and nivolumab can influence the immune system's response to HPV-associated head and neck cancer, and we wish to evaluate whether taking 5-azacytidine will make HPV-associated head and neck cancer more sensitive to treatment with nivolumab.

5-Azacytidine (5-AZA) is a chemotherapy, and nivolumab is an immunotherapy. Both drugs are approved for use in the US by the Food and Drug Administration (FDA) for use in the treatment of different types of cancer, and nivolumab is approved for use in head and neck cancer that has previously been treated with chemotherapy. Because they are not approved to be used together in HPV-associated head and neck cancer, these drugs are considered experimental in this study. For this study, the drugs will be used either together or separately.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients with resectable squamous cell carcinoma of the oropharynx. Histologic or cytologic confirmation from either a biopsy/aspirate of the oropharyngeal primary lesion and/or a regional lymph node is required.

T1-T3, N0-N2, M0 stage by AJCC 8th edition for HPV-initiated oropharynx cancer.

Resectability confirmed by a surgical co-investigator; evaluation may include operative endoscopy to discover second primaries and map tumor extent with biopsy

In addition to diagnostic biopsies, biopsies in clinic or at the time of operative endoscopy are required to yield primary tumor for research purposes > 3mm cup forceps biopsies X 3. Prior biopsies for research obtained with informed consent for the Yale Biosample Repository Protocol are acceptable if they meet the volume requirements above.

Disqualifiers

Medical contraindication to transoral surgery.

Full dose anticoagulation.

Concomitant invasive malignancy, or malignancy within 2 years except for hormonally responsive breast or prostate cancer, resected non-melanoma skin cancer, resected uterine cervical carcinoma or meningioma.

Inability to give informed consent.

Trial design

Design model

Parallel

Treatments tested in this trial

  • Combination 5-azacytidine and nivolumab

    Drug

    The primary objective of the study is to determine whether exposure to the demethylating agent 5-azacytidine will sensitize HPV-associated oropharynx cancer to nivolumab by induction of interferon response, neoantigen expression, and augmentation of lymphocyte infiltration of the tumor microenvironment.

  • Nivolumab

    Drug

    Immunotherapy is a type of treatment that uses your body's own immune system to help fight cancer. Specifically, Nivolumab belongs to a class of anti-cancer drugs known as immune checkpoint inhibitors. Cancer cells are able to "turn off" the immune system by increasing the production of a protein called PD-1. Nivolumab can block PD-1 and may be able to re-activate the immune response to kill head and neck cancer cells.

2

Secondary correlative evidence of anti-tumor response

As captured with tumoral Ki-67 and caspase staining on pre- and post-treatment specimens.

Time frame

3

Secondary correlative evidence of disease control

As measured by the HPV ctDNA with the NavDx assay

baseline; 14-30 days prior to surgery, 30 and 90 days post resection surgery
4

Occurrence of toxicity

Adverse Events occurrence (Common Toxicity Criteria for Adverse Events), Immune-related adverse events of special interest, and hyperprogression will be captured.
