Overview

Study Title

A Phase II/III Randomized Study of Maintenance Nivolumab versus Observation in Patients with Locally Advanced, Intermediate Risk HPV Positive OPCA

Summary

This phase II/III trials studies whether maintenance immunotherapy (nivolumab) following definitive treatment with radiation and chemotherapy (cisplatin) result in significant improvement in overall survival (time being alive) and progression-free survival (time being alive without cancer) for patients with intermediate risk human papillomavirus (HPV) positive oropharynx cancer that has spread to nearby tissue or lymph nodes. Drugs used in chemotherapy such as cisplatin work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether chemotherapy and radiation therapy followed by maintenance nivolumab therapy works better than chemotherapy and radiation therapy alone in treating patients with HPV positive oropharyngeal cancer.

Objective

Primary Objective for Phase 2: To assess the efficacy of concurrent definitive therapy followed by nivolumab compared with concurrent definitive therapy followed by observation in terms of progression-free survival (PFS). Primary Objective for Phase 3: To assess the efficacy of concurrent definitive therapy followed by nivolumab compared with concurrent definitive therapy followed by observation in terms of overall survival (OS). Secondary Objectives: To further assess the efficacy of nivolumab compared with observation in terms of: The relationship of baseline PD-L1 expression to clinical outcome. To evaluate the predictive value of HPV16 E6 and E7 DNA in saliva and plasma, at baseline, 12 weeks and 9 months after completion of radiation on PFS and OS in both arms of the study. To evaluate the tumor mutation burden by whole exome sequencing of the initial pretreatment tissue sample as well as samples obtained at the time of progression. To evaluate the association of 12 week post therapy FDG PET/CT with PFS and OS. To establish the prognostic value of SUVmax of primary tumor or neck nodal metastasis of baseline FDG PET/CT for OS (and/or PFS). To correlate SUVmax of primary tumor or nodal metastasis of baseline FDG PET/CT with PD-L1 expression (positive vs. negative). To correlate the post therapy (cisplatin + RT) FDG PET/CT with saliva or plasma levels of HPV DNA collected at the time of the standard 3 months PET/CT scan as well as 6 months later (i.e. 9 months post therapy) for both the observation and Nivolumab groups. To compare the PET based therapy response assessment(Hopkins criteria) to the RECIST 1.1 assessment at 12 week post chemoradiation therapy, for patients who have a PET/CT scan at 12 weeks.

  • Participants must have tumor measurements with CT of neck and CT of chest (or CT of neck and FDG PET/CT if standard of care) within 4 weeks prior to Step 1 randomization.
  • Participants must have progression per RECIST criteria AND tissue-proven progression on Arm B treatment within 12 months after completion of radiation therapy.
  • ECOG performance status of 0 or 1.
  • Participants must not have known hypersensitivity to nivolumab or compounds of similar chemical or biologic composition.
