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

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.

Detailed Description
  • Research Hypothesis The presence of VCN-01 into the tumor after systemic administration will help to overcome the observed resistance to durvalumab and other PD1/PD-L1 checkpoint inhibitors.
  • Primary objectives To evaluate the safety and tolerability of a single intravenous injection of VCN-01 combined with durvalumab in two administration regimens (concomitant or durvalumab starting two weeks later "sequential schedule"), and to determine the recommended phase II dose (RP2D) of the combination.
  • Study design This is a phase I trial, multicenter, open label, and dose escalation study. Patients will be entered at each dose level, according to a planned dose escalation schedule. Absence of unacceptable toxicity at the previous dose is required for entering a patient in the subsequent level.
  • Number of Centers: up to 3
  • Number of Patients: 15-20 patients
  • Study Population: Patients with metastatic squamous cell carcinoma of the head and neck who have progressed during or after treatment with immune-checkpoint inhibitors.
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Intervention Model Description:

This is a phase I trial, multicenter, open label, and dose escalation study. Patients will be entered at each dose level, according to a planned dose escalation schedule. Absence of unacceptable toxicity at the previous dose is required for entering a patient in the subsequent level.

The investigational treatment will be a single i.v. VCN-01 dose combined with concomitant i.v. durvalumab (MEDI4736) 1500 mg Q4W (Arm I) or durvalumab starting two weeks after VCN-01 administration, "sequential schedule" (Arm II). Patient recruitment in Arm I and Arm II will be performed in parallel based on slot availability. Only one single dose of VCN-01 will be administered to each patient during the trial. Durvalumab will be administered Q4W until disease progression, unacceptable toxicity, withdrawal of consent, or another discontinuation criterion.
