The purpose of this study is to determine the safety and tolerability of GL-ONC1 administered intravenously in combination with radiation therapy and cisplatin (CDDP)in patients with locoregionally advanced head and neck cancer.
GL-ONC1, an oncolytic vaccinia virus, has shown the ability to preferentially locate, colonize and destroy tumor cells in more than 40 different human tumors. A First-in-Man, Phase I clinical study focusing on the safety and tolerability of GL-ONC1 intravenously administered to patients with a variety of advanced solid tumor entities has shown that GL-ONC1 is well-tolerated at therapeutic dose levels, with documented evidence of antitumor activity. Preclinical studies have further shown synergistic effects with the use of chemotherapy (Cisplatin) and viral therapy with GL-ONC, as well as favorable results when cancer cells are irradiated and then treated with GL-ONC1 in animal models. This Phase I study seeks to evaluate the safety, tolerability and early signs of efficacy of GL-ONC1 administered intravenously in combination with standard of care (SOC) radiation therapy (RT) and cisplatin (CDDP)in patients with locoregionally advanced head and neck cancer. Patients will be individually assessed for safety and dose limiting toxicity. Viral colonization in tumors, replication and anti-tumoral activity will also be evaluated.

Safety and Tolerability as measured by the number of patients with Adverse Events, as well as type of AE and frequency
Evaluation of changes in laboratory tests (hematological, chemistry), immunogenicity and physical examination
Time frame: Baseline up to week 23 Post-treatment
Presence of Virus in Tumor
Analysis of tumor tissue (obtained through surgical or core biopsy if accessible from consenting patients) following viral treatment.
Time frame: At baseline (Within 4 weeks of Treatment Day 1); 9-13 days post viral injection
Determine Initial Susceptibility of tumor to viral infection
Evaluate susceptibility of initial biopsied tumor to viral infection in cell cultures (for patients consenting to biopsy and where tumor is accessible).
Time frame: At baseline (Within 4 weeks of Treatment Day 1)
Anti-Tumor Activity (Early Efficacy)
Assessing changes in tumor measurement through physical examination, CT or CT/PET scan
Time frame: Change from baseline up to week 23 Post-treatment (week 23)
