Study of Safety and Tolerability of Nivolumab Treatment Alone or in Combination With Relatlimab or Ipilimumab in Head and Neck Cancer

The aim of this study is to potentiate adaptive immunity to enhance the anti-tumor activity of anti-PD1 antibody by the addition of anti-CTLA4 antibody or anti-LAG3 antibody (relatlimab) given in subjects with resectable locally advanced HNSCC prior to surgical resection.

Immunotherapeutic agents have been well tolerated in the recurrent/metastatic patient population. Studies have shown that delay of surgical resection for 3-4 weeks after diagnosis is acceptable. Overall survival for locally advanced head and neck squamous cell carcinoma are poor with the current treatment modalities available. Previously untreated, locally advanced (AJCC 8th edition stage III-IVa) HPV+ and HPV- head and neck squamous cell carcinoma patients who are candidates for surgical resection, as deemed by the multidisciplinary team will be included in this trial. Patients with histories of autoimmune disease or with current or previous histories of immune modulating agents will be excluded from participation. Relatlimab will be given IV at a dose of 480 mg IV on D1 (and on D28 if surgery is postponed at the discretion of the investigator). Nivolumab will be given IV at a dose of 480 mg on D1 (and on D28 if surgery is postponed at the discretion of the investigator) when given alone or with relatlimab. Nivolumab will be given at dose of 3 mg/kg IV every 2 weeks on D1 and D14 (and on D28 if the operating room time is not yet available, and the 4-week CT scan demonstrates at least stable disease ) when given with Ipilimumab. Ipilimumab will be given at a dose of 1 mg/kg IV once only on D1. Patients will undergo biopsy and CT scan prior to treatment initiation. 4 weeks (± 1 week) after, patient will undergo surgical resection. CT scan will be repeated prior to surgery (from 1-72 hours prior to surgery).The patients will be monitored from time of biopsy until 6 months postoperatively.
