Safety,Tolerability,and Efficacy of VCN-01 With Durvalumab in R/M Head and Neck Squamous Cell Carcinoma

This is a Phase I Study to Evaluate the Safety, Tolerability, and Efficacy of VCN-01 in Combination With Durvalumab (MEDI4736) in Subjects With Recurrent/Metastatic Squamous Cell Carcinoma of the Head and Neck. VCN-01 is a genetically modified oncolytic adenovirus characterized by the presence of four independent genetic modifications on the backbone of the wild-type HAd5 adenovirus genome, encoding human PH20, that confer tumor selectivity and anti-tumor activity. Durvalumab is a human monoclonal antibody (mAb) of the immunoglobulin G (IgG) 1 kappa subclass that inhibits binding of PD-L1. The proposed mechanism of action (MOA) for durvalumab is interference in the interaction of PD-L1 with PD-1 and CD80 (B7.1). Blockade of PD-L1/PD-1 and PD-L1/CD80 interactions releases the inhibition of immune responses, including those that may result in tumor elimination.
