Summary
Background about the treatments
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. Chemotherapy drugs, such as gemcitabine and 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 x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors.
Researchers want to find out what effects, good and/or bad, adding nivolumab to chemotherapy has on patients with newly diagnosed nasopharyngeal carcinoma (NPC). In addition, they want to find out if children with NPC may be treated with less radiation therapy and whether this decreases the side effects of therapy.
How this study works
All eligible participants will receive the following treatment.
INDUCTION THERAPY: Patients receive nivolumab intravenously (IV) over 30 minutes on day 1 of each cycle, gemcitabine IV over 30 minutes on days 1 and 8 of each cycle, and cisplatin IV over 3-6 hours on day 1 of each cycle. Treatment repeats every 21 days for 3 cycles in the absence of disease progression or unacceptable toxicity.
CONSOLIDATION THERAPY: Patients receive nivolumab IV over 30 minutes on day 1 of each cycle and cisplatin IV over 3-6 hours on day 1 of cycles 1-2. Treatment repeats every 21 days for 3 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive concurrent radiation therapy on trial.
MAINTENANCE THERAPY: Patients receive nivolumab IV over 30 minutes on day 1 of each cycle. Treatment repeats every 28 days for 6 cycles in the absence of disease progression or unacceptable toxicity.
Patients also undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening and as clinically indicated on trial. Patients undergo MRI, FDG PET, and computed tomography (CT) throughout the trial and chest x-ray during follow-up. Patients also undergo dental x-ray imaging on the trial. Patients may optionally undergo tissue biopsy, blood and stool sample collection during screening and on trial.
After completion of study treatment, patients are followed up every 3 months for 12 months, every 6 months until 24 months off therapy, and then yearly until 5 years off therapy.
