Nivolumab with Relatlimab or Ipilimumab for the Treatment of Recurrent and/or Metastatic Head and Neck Squamous Cell Cancer

Trial Status: closed to accrual

This phase II trial investigates how well nivolumab with relatlimab or ipilimumab work in treating patients with head and neck squamous cell cancer that has come back (recurrent) and/or has spread to other places in the body (metastatic) and has progressed on prior immunotherapy. Immunotherapy drugs are drugs that work by trying to get the immune system to attack cancer. Comparing the immune system to a car, there are two ways to make a car go faster. One is to press on the gas pedal and the other is to take the foot of the brake. The immune system has many “gas pedals” and “brakes” in order to help it decide whether to attack or not attack. The drugs nivolumab, relatlimab, and ipilimumab are antibodies (a type of protein) that work by blocking a “brake” (akin to taking the foot off the brake in the car) on the immune system cells which can lead to the immune system attacking the cancer. Each drug blocks a different brake. Nivolumab blocks PD-1, relatlimab blocks LAG-3, and ipilimumab blocks CTLA4. Giving nivolumab together with relatlimab or ipilimumab may cause the tumor to shrink in size.
