Oncolytics Biotech® Inc. Collaborators Present Positive Data Correlating Specific Biomarkers with Survival in NSCLC Patients Treated with REOLYSIN®, Carboplatin and Paclitaxel

CALGARY, Oct. 28, 2013 /PRNewswire/ – Oncolytics Biotech Inc. (“Oncolytics”)
(TSX:ONC) (NASDAQ:ONCY) today announced a poster presentation
containing updated efficacy data from a Phase 2 study examining the use
of REOLYSIN® in combination with carboplatin and paclitaxel in patients with stage
IV non-small cell lung cancer (NSCLC) with Kras or EGFR-activated tumors (REO 016) was made at International
Association for the Study of Lung Cancer (IASLC). The conference is
being held from October 27th to 30th, 2013 in Sydney, Australia.

The poster presentation included new efficacy data that correlated a
number of molecular abnormalities with best response, progression free
survival (PFS) and one-year survival. Current data in these patients
demonstrates that 20 of 36 evaluable patients (56%) survived a year or
more. There were 13 patients with only EGFR mutations or
amplifications, of whom nine (69.2%) survived a year or longer. Four of
four (100%) patients with BRAF and EGFR amplification survived a year
or longer.

“This is the first time we have reported data correlating the presence
of specific biomarkers with efficacy, which covers both best response
and survival in patient tumours with a Ras-activated pathway,” said Dr.
Brad Thompson, President and CEO of Oncolytics. “Although the study
examined a relatively small number of patients, this data is
encouraging, especially in light of a growing focus among healthcare
professionals on personalizing cancer treatment based on tumour type.
We are taking a closer look at the specific role biomarkers play in a
number of our ongoing studies and, based on this data, intend to
conduct a randomized trial in this indication.”

The chart below summarizes key findings for the 36 evaluable patients:

Number of
Best Response Number
progression free
at six months
surviving one
BRAF mutation,
4 2 PR, 1 SD, 1 PD 2 4
10 5 PR, 5 SD 4 7
EGFR mutation,
3 1 PR, 1 SD, 1 PD 1 2
KRAS 12 3 PR, 8 SD 6 4
7 6 SD, 1 PD 1 3
Total 36 11 PR, 11 SD
(30% response rate)
14 (38%) 20 (56%)

Partial response (PR), stable disease (SD), progressive disease (PD)

Patients received REOLYSIN (3 x 1010 TCID50) intravenously daily on days one to five, in combination with paclitaxel
at initial doses of paclitaxel 175 mg/m2 and carboplatin AUC 5, on day one of each 21-day cycle. Overall, 37
patients received 209 cycles (per patient median four, range one to
18). The study treatment was found to be well tolerated.

The Company’s collaborators also presented a poster on results from the
Company’s 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). This is the same poster that was previously
presented on October 22, 2013 at the AACR-NCI-EORTC International
Conference on Molecular Targets and Cancer Therapeutics conference held
in Boston, MA.

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,
