Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	Baseline up to week 23 Post-treatment	Yes
Secondary	Presence of Virus in Tumor	Analysis of tumor tissue (obtained through surgical or core biopsy if accessible from consenting patients) following viral treatment.	At baseline (Within 4 weeks of Treatment Day 1); 9-13 days post viral injection	No
Secondary	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).	At baseline (Within 4 weeks of Treatment Day 1)	No
Secondary	Anti-Tumor Activity (Early Efficacy)	Assessing changes in tumor measurement through physical examination, CT or CT/PET scan	Change from baseline up to week 23 Post-treatment (week 23)	No
