Safety Study of Attenuated Vaccinia Virus (GL-ONC1)With Combination Therapy in Head & Neck Cancer

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01584284
Recruitment Status : Completed
First Posted : April 24, 2012

Brief 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.

Condition or disease Intervention/treatment Phase
Cancer of Head and Neck Biological: GL-ONC1 Phase 1

Detailed 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.

Intervention Details:
  • Biological: GL-ONC1
    A genetically-engineered vaccinia virus administered via intravenous infusion . Cohorts 1, 2, 3: Frequency: 1x in Week 1; Cohort 4: 1x again 1x in Week 2; Cohort 5: 1x Week 1, 1x Week 2, 1x Week 3, 1x Week 4.

Primary Outcome Measures :
  1. Safety and Tolerability as measured by the number of patients with Adverse Events, as well as type of AE and frequency [ Time Frame: Baseline up to week 23 Post-treatment ]
    Evaluation of changes in laboratory tests (hematological, chemistry), immunogenicity and physical examination

Secondary Outcome Measures :
  1. Presence of Virus in Tumor [ Time Frame: At baseline (Within 4 weeks of Treatment Day 1); 9-13 days post viral injection ]
    Analysis of tumor tissue (obtained through surgical or core biopsy if accessible from consenting patients) following viral treatment.

  2. Determine Initial Susceptibility of tumor to viral infection [ Time Frame: At baseline (Within 4 weeks of Treatment Day 1) ]
    Evaluate susceptibility of initial biopsied tumor to viral infection in cell cultures (for patients consenting to biopsy and where tumor is accessible).

  3. Anti-Tumor Activity (Early Efficacy) [ Time Frame: Change from baseline up to week 23 Post-treatment (week 23) ]
    Assessing changes in tumor measurement through physical examination, CT or CT/PET scan
