"2010 was marked by the further expansion of our late-stage clinical program, particularly with respect to the addition of randomized trials and new indications," said Dr. Brad Thompson, President and CEO of Oncolytics.

Selected Highlights

Since January 1, 2010 the Company has announced:

Clinical Trial Results

• A poster presentation at the ASCO 2010 Annual Meeting, entitled "A Phase I/II study of oncolytic reovirus plus carboplatin/paclitaxel in patients with advanced solid cancers with emphasis on squamous cell carcinoma of the head and neck (SCCHN)," showing that of 19 head and neck cancer patients evaluable for response, eight (42%) had partial responses and six (32%) had stable disease; mean overall survival in 24 treated head and neck cancer patients was more than eight months;
• Presentation of interim data from a U.K. translational clinical trial investigating intravenous administration of REOLYSIN^® in patients with metastatic colorectal cancer prior to surgical resection of liver metastases. The researchers concluded that reovirus can be successfully delivered specifically to colorectal liver metastases following intravenous administration as a monotherapy and that pre-operative treatment was safe, suggesting that application of oncolytic viral therapy can be widened to the neoadjuvant setting;
• Publication of a paper entitled "REO-10: A Phase I Study of Intravenous Reovirus and Docetaxel in Patients with Advanced Cancer," by Comins et al in the journal Clinical Cancer Research. The paper reported final results from a combination REOLYSIN and docetaxel trial designed to evaluate the anti-tumour effects of systemic administration of REOLYSIN in combination with docetaxel (Taxotere^®) in patients with advanced cancers. A disease control rate (combined complete response, partial response and stable disease) of 88% was observed. The authors concluded that the combination of reovirus and docetaxel was safe, with evidence of objective disease response, and warrants further evaluation in a Phase II study;
• Start of enrollment and preliminary results from a U.S. Phase 2 clinical trial (REO 017) using intravenous administration of REOLYSIN in combination with gemcitabine (Gemzar^®) in patients with advanced pancreatic cancer. Seventeen evaluable patients with pancreatic cancer were expected to be treated in the first stage and if three or more patients received clinical benefit, the study would then proceed to the next stage. This endpoint was met after six evaluable patients were enrolled.

Ongoing Clinical Program

• Opening of enrollment in a Phase 3 trial examining REOLYSIN in combination with paclitaxel and carboplatin in patients with platinum-refractory head and neck cancers;
• The Cancer Therapy & Research Center at the University of Texas Health Science Center (CTRC) had started patient enrolment in a U.S. Phase 2 clinical trial using intravenous administration of REOLYSIN in combination with carboplatin and paclitaxel in patients with squamous cell carcinoma of the lungs (SCC lung cancer);
• Completion of Phase 1 patient enrollment in a Phase 1/2 clinical trial to investigate the use of REOLYSIN for patients with recurrent malignant gliomas (REO 007);
• The opening of enrollment in a U.S. Phase 1 study of REOLYSIN in combination with FOLFIRI (Folinic Acid (leucovorin) + Fluorouracil (5-FU) + Irinotecan) in patients with oxaliplatin refractory/intolerant Kras mutant colorectal cancer (REO 022);
• Start of enrollment in a randomized Phase 2 trial of weekly paclitaxel versus weekly paclitaxel with REOLYSIN in patients with persistent or recurrent, ovarian, fallopian tube or primary peritoneal cancer to be conducted by the Gynecologic Oncology Group (GOG) and sponsored by The Cancer Therapy Evaluation Program, Division of Cancer Treatment and Diagnosis, U.S. NCI, which is part of the National Institutes of Health;
• The Children's Oncology Group (COG) intent to conduct a Phase 1 trial of REOLYSIN in combination with cyclophosphamide in pediatric patients with relapsed or refractory solid tumors sponsored by the NCI;
• Start of enrollment in a 2-Arm randomized Phase 2 study of carboplatin, paclitaxel plus REOLYSIN versus carboplatin and paclitaxel alone in the first line treatment of patients with recurrent or metastatic pancreatic cancer sponsored by the NCI;
• Completion of enrollment in a U.K. translational clinical trial investigating intravenous administration of REOLYSIN in patients with metastatic colorectal cancer prior to surgical resection of liver metastases (REO 013);

Intellectual Property
