Prospective, open-label, phase 1 study of CD40 agonist (LVGN7409) and PD-1 inhibition (LVGN3616 or nivolumab) in patients with resectable Human Papillomavirus (HPV)-negative mucosal head/neck squamous cell carcinoma (HNSCC). This protocol proposes to study the safety and immunological effects of LVGN7409, a CD40 agonistic antibody, when administered in combination with PD-1 inhibition prior to surgical resection.
