Brief Summary:
The purpose of this study is to evaluate the safety of the investigational product GL-ONC1. GL-ONC1, a vaccinia virus, has been genetically modified for use as a potential anti-cancer drug to destroy cancer cells. Vaccinia virus has been used successfully in the past as smallpox vaccine in millions of people worldwide.

Condition or disease Intervention/treatment Phase
Solid Organ Cancers Biological: GL-ONC1 Phase 1

Detailed Description:

This is an open-label, non-randomized Phase 1b dose escalation study evaluating the safety and effect of the oncolytic virus GL-ONC1 administered intravenously, with or without eculizumab, prior to surgery in patients with advanced solid organ tumors.

GL-ONC1 is a genetically engineered oncolytic vaccinia virus, which disrupts nonessential genes and expression of the foreign gene expression. Evidence suggest that GL-ONC1 is able to infect tumor tissue and kill tumor cells.

The goals of this study are to evaluate the safety of GL-ONC1 and to assess the pharmacokinetics and pharmacodynamics profile of GL-ONC1 in vivo.
