About Oncolytics Biotech Inc.
Oncolytics is a Calgary-based biotechnology company focused on the development of the human reovirus (REOLYSIN®) as a potential cancer therapeutic. Oncolytics’ researchers have demonstrated that the reovirus is able to selectively kill cancer cells and, in vitro, kill human cancer cells derived from many types of cancer including breast, prostate, pancreatic and brain tumours. Research has also yielded successful cancer treatment results in a number of animal models. Phase I clinical trial results have indicated that there were no toxicology-related issues with the administration of the reovirus, and that the reovirus demonstrated activity in injected tumours. Oncolytics is currently conducting a T2 prostate cancer trial, and a Phase I/II recurrent malignant glioma (brain cancer) trial.
