Oncolytics Biotech® Inc. Announces Positive Final Tumour Response Data for U.S. Phase 2 Study of REOLYSIN® in Squamous Cell Lung Cancer

September 9, 2013

CALGARY, Sept. 9, 2013 /PRNewswire/ – Oncolytics Biotech Inc. (“Oncolytics”)
(TSX:ONC) (NASDAQ:ONCY) today announced final tumour response data from
its U.S. Phase 2 single arm clinical trial in patients with squamous
cell carcinoma of the lung (SCCLC) using intravenous administration of
REOLYSIN in combination with carboplatin and paclitaxel (REO 021).

The analysis examined percent best overall tumour responses between
pre-treatment and up to six treatment cycles. Of 25 evaluable patients
who had more than one cycle of therapy, 23 (92%) exhibited overall
tumour shrinkage (mean shrinkage was 32.7%). Of the 25 evaluable
patients, 10 (40%) had partial responses (PRs), while a further 13
(52%) showed stable disease (SD) and two (8%), had progressive disease
(PD), for a disease control rate (complete response (CR) + PR + SD) of
92%. A waterfall graph showing individual patient data will be
available on the Company’s website at http://www.oncolyticsbiotech.com/presentations.

“We are thrilled to have demonstrated 92% overall tumour shrinkage in
this group of patients,” said Dr. Brad Thompson, President and CEO of
Oncolytics. “Squamous cell carcinoma of the lung is notoriously
difficult to treat, and these results support further investigation of
REOLYSIN in randomized clinical trials for this indication.”

The study enrolled patients with metastatic stage IIIB or stage IV, or
recurrent, squamous cell carcinoma of the lung, who were
chemotherapy-naïve for their metastatic or recurrent cancer. The
primary objective of the trial is to evaluate the patients’ tumour
response. The secondary objectives are to assess progression-free
survival and overall survival for the treatment regimen in the study
population; to determine the proportion of patients receiving the above
treatment who were alive and free of disease progression at six months;
and to assess the safety and tolerability of the treatment regimen in
the study population. Final progression-free survival and safety data
for the study will be reported later in 2013.

About Lung Cancer

The American Cancer Society estimates that in 2013, approximately
228,190 new cases of lung cancer will be diagnosed. Between 85% and 90%
of all lung cancers are classified as non-small cell lung cancer
(NSCLC); squamous cell carcinomas account for 25-30% of all lung
cancers. Lung cancer is by far the leading cause of cancer death among
both men and women. There will be an estimated 159,480 deaths from lung
cancer in the United States in 2013, accounting for around 27% of all
cancer deaths. Lung cancer is the leading cause of cancer death, with
more people dying each year of lung cancer than from colon, breast, and
prostate cancers combined. For more information about SCC lung cancer,
