Testing Immunotherapy Versus Observation in Patients With HPV Throat Cancer

• Status: Recruiting
• Trial end date: 2027-01-01
• Target enrollment: 0
• Participant gender: All

Summary

This phase 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 (throat 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.

All patients of childbearing potential must have a blood test or urine study within 2 weeks prior to randomization to rule out pregnancy. A patient of childbearing potential is any female, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) has achieved menarche at some point, 2) has not undergone a hysterectomy or bilateral oophorectomy or 3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).

• STEP 1: Patients of childbearing potential must use an accepted and effective method of contraception or abstain from sexual intercourse for at least one week prior to the start of treatment, and continue for 5 months after the last dose of protocol treatment. Patients must also not donate ova during this same time period.
