Company: Oncolytics Biotech Inc.
Filing Type: Form 6-K (Report of Foreign Private Issuer)
Date: September 28, 2007

Key Financial Metrics
This filing is a non-financial report focused on clinical trial progress. The text does not provide specific values for revenue, profit, cash flow, margins, debt, or liquidity. As a biotechnology company in the development phase, financial performance is not the subject of this specific disclosure.
Material Changes and Clinical Results
The primary material event is the announcement of interim data from the U.K. Phase Ia/Ib combination trial:
- Study Status: 22 patients treated to date; 15 completed the study, 5 withdrew, and 2 remain on study.
- Phase Ia Results (11 patients):
- Three patients (oesophageal, squamous skin carcinoma, squamous cell scalp) experienced significant partial responses.
- Oesophageal Patient: Target tumor reduced by 28.5% at one month and 64% at two to three months. Stable disease observed in four non-treated tumors, including a 15% volume reduction in non-treated mediastinal disease maintained for over six months.
- Squamous Skin Cancer Patient: 50% reduction in target tumor; stable disease in two non-treated tumors.
- Squamous Cell Scalp Patient: Stable disease for two months followed by partial response at three months; stable disease in one non-treated tumor.
- Phase Ib Results (6 patients completed):
- Three patients (colorectal, melanoma, lung cancer) experienced tumor regression in target tumors and stable disease in non-treated tumors.
- Colorectal Patient: Partial response with >50% regression in target tumor; stable disease in four non-treated tumors.
- Melanoma Patient: Minor regression in target tumor; stable disease in two non-treated tumors.
- Lung Cancer Patient: Minor regression in target tumor; stable disease in three non-treated tumors.
- Safety Profile: Treatment was well tolerated. Toxicities were mostly Grade 1 or 2 (fatigue, lymphopenia, fever, neutropenia). Grade 3 toxicities (cellulitis, dysphasia, diarrhea) were attributed to disease progression rather than the combination treatment. Viral replication was unaffected by radiation.
Guidance, Outlook, and Risks
Outlook and Events:
- Final results are expected to be announced following further data evaluation.
- Interim results were scheduled for presentation at the National Cancer Research Institute (NCRI) conference on October 2, 2007, in Birmingham, U.K.
- Further results were scheduled for the AACR-NCI-EORTC International Conference in San Francisco, October 22-26, 2007.
- The filing contains forward-looking statements subject to risks including the availability of funds, efficacy of REOLYSIN, success of clinical trials, commercialization capabilities, and regulatory uncertainties.
- Management cautions investors against placing undue reliance on forward-looking statements.
Investor Verification Checklist
- Verify the presentation of final results at the upcoming NCRI and AACR-NCI-EORTC conferences.
- Monitor the company's cash position and funding status, as the filing notes "availability of funds" as a key risk for R&D projects.
- Review subsequent filings for the full safety data and long-term follow-up on the 22 patients treated.
- Confirm the regulatory pathway for REOLYSIN in the U.K. and U.S. following these positive interim signals.
