Oncolytics Biotech(R) Inc. Announces Reovirus Research to be Presented at AACR Annual Meeting

April 14, 2010

CALGARY, April 14 /PRNewswire-FirstCall/ – Oncolytics Biotech Inc. (“Oncolytics”) (TSX:ONC, NASDAQ:ONCY) announced today that abstracts covering both clinical and preclinical research with reovirus (REOLYSIN(R)) are available on the American Association for Cancer Research (AACR) website at www.aacr.org, and on the Oncolytics website at www.oncolyticsbiotech.com. The research is scheduled to be delivered at the 101st AACR Annual Meeting in Washington, DC, April 17-21, 2010.

“Our preclinical and clinical collaborations continue to support and improve our understanding of how reovirus works, as well as its broad applicability in a growing range of potential cancer indications,” said Dr. Matt Coffey, COO of Oncolytics.

The first abstract, entitled “Reovirus replication in ovarian and peritoneal tumors after intravenous administration,” covers correlative results from a Phase 1/2 study with reovirus, sponsored by the National Cancer Institute under its Clinical Trials Agreement with Oncolytics, in patients with ovarian, primary peritoneal and fallopian tube carcinoma.

The results provide evidence of viral targeting and replication in peritoneal and ovarian cancer cells after intravenous administration of reovirus to patients. The poster is scheduled to be presented on Monday, April 19, 2010.

The second abstract, entitled “Molecular pathways associated with REOLYSIN and gemcitabine synergy in ras-mutated human HCT116 cells,” covers work done to better understand the mechanisms associated with the cytotoxic synergies in this combined approach.

The investigators concluded that the top three canonical pathways significantly affected by the combination treatment were interferon signaling, antigen presentation and the protein ubiquitination pathways. These data suggest that the combination of gemcitabine and REOLYSIN stimulates the immune system to increase surveillance/recognition of cancer cells. The poster is scheduled to be presented on Monday, April 19, 2010.

The third abstract, entitled “The addition of REOLYSIN, an oncolytic reovirus, to irinotecan shows synergistic anticancer activity in colorectal cancer cell lines,” covers research done in vitro into a novel therapeutic approach for treating patients with colorectal cancer tumors that harbor a mutation in the Kras oncogene that have failed first line therapy.

The investigators found that when REOLYSIN was combined with irinotecan, there was evidence of synergistic cytotoxicity in seven of eight tested cell lines and concluded that the combination of REOLYSIN and irinotecan is synergistic in colorectal cancer cell lines, including those with Kras mutation, and is worthy of exploration in human patients. The poster is scheduled to be presented on Monday, April 19, 2010.

The fourth abstract, entitled “Reovirus successfully purges multiple myeloma ex vivo and does not affect human CD34+ cell engraftment in a murine transplantation model,” covers the utility of reovirus in treating hematological malignancies.

The investigators concluded that the sensitivity of reovirus towards multiple myeloma and its lack of effect on human stem cells highlight the potential of reovirus as an ex vivo purging agent during autologous hematopoietic stem cell transplants for multiple myeloma. The poster is scheduled to be presented on Sunday, April 18, 2010.
