4. REOLYSIN® Overview
REOLYSIN® is a proprietary isolate of the reovirus
o
o
Reovirus is a replication competent virus and is considered safe to humans
REOLYSIN® has been safely administered to patients via intravenous,
intratumoral and intrathecal injection
Mechanism of Action:
o
o
o
o
o
In Ras-activated cells, one of the key cellular defence mechanisms against
double-stranded RNA viral infection, Protein Kinase-R (PKR), is deactivated
This specific vulnerability of constitutive Ras-activated cancer cells to the
reovirus is the basis of REOLYSIN®’s activity and specificity
Reovirus oncolysis is seen in cancer cells with constitute Ras pathway
activation; susceptible cancer cells therefore include those with either:
o
o
o
1
2
EGFR overexpression or mutation1; or
Ras mutation, which includes Kras mutation2
Both of these mutations lead to activation of the Ras pathway

o
Image shows positive (red
staining) for reovirus in the
metastatic lesions (blue arrow)
and negative for reovirus in the
normal cells (red arrow)
Nine out of ten patients showed
the same pattern, i.e. targeted
delivery to metastatic tumor
lesions of the liver
In addition, two of the ten
patients had complete tumor
necrosis
This demonstrates that
REOLYSIN® specifically accesses
and replicates in metastatic
colorectal cancer when delivered
as a monotherapy

7. Market for Ras Pathway Mediated Cancers
o
o
o
Estimated global cancer market was $77 billion in 2011; this is
expected to rise to $105 billion in 2016
At least five million new patients per year are expected to
develop cancers with a Ras pathway involvement
In the developed world alone, at least 2.6 million patients per
year die of cancers that have metastasized
7
8. REOLYSIN® Clinical Program Overview
REOLYSIN® has been utilized in studies in over 1,000 patients
In total, nearly thirty ongoing or completed clinical trials including:
o Seven randomized Phase II and Phase III clinical trials, including Phase III
head and neck cancer and Phase II trials for ovarian, pancreatic, prostate,
colorectal, non-small cell lung and breast cancers
o Nine single arm studies in the following indications:
o Phase II trials:
o
o
Company sponsored: pancreatic cancer, non-small cell lung cancer, head and neck carcinoma,
metastatic melanoma and squamous cell carcinoma
Phase I trials:
o
o
Company sponsored: colorectal cancer and advanced malignancies
Investigator sponsored: multiple myeloma and relapsed or refractory solid tumors

10. Phase III (Pivotal) Program for REOLYSIN®
in Squamous Cell Head & Neck Cancers
o
In Q3 2012, Oncolytics completed enrollment in REO 018, a randomized, two stage, two-arm,
double-blind, multi-center trial examining REOLYSIN® in combination with carboplatin and
paclitaxel in taxane-naïve patients with platinum-refractory recurrent head and neck cancers
o
o
The study was approved and run in fourteen countries in North America and Europe
Patients in the REO 018 study were stratified for:
o
ECOG performance status (0-1 versus 2)
o
Time of progression/relapse after prior platinum-based chemotherapy
o
o
Disease location (patients with locally recurrent disease, with or without distal metastases, versus patients
with metastatic disease only)
REO 018 Endpoints:
o
o
Secondary Endpoints: Progression-Free Survival (PFS), best response and tumour-specific response
o
o
Primary Endpoint: Overall Survival (OS)
Pharmacodynamic Endpoints: Tumour Ras pathway status and HPV status
The Company intends to treat REO 018 as a separate supportive study to a planned randomized,
follow-on international Phase III head and neck registration study in patients with loco-regional
head and neck cancer
10
11. REO 018: Tumor Specific Response Data
o
o
Data announced December 13, 2012
Endpoint examines initial percentage tumor changes between
baseline and first post treatment scans in all patients,
differentiating between loco-regional tumours and metastatic
tumours
o
o
o
This is a measure of rate or velocity of response, not magnitude of
response
The endpoint was introduced to determine if REOLYSIN® adds
tumor specific differential activity in metastatic and loco-regional
disease in a randomized setting
Of the total 105 patients with evaluable metastatic tumors, 86%
(n=50) of those in the test, and 67% (n=55) in the control arm, arm
had tumor stabilization (0% growth) or shrinkage
o
This is a statistically significant difference, with a p-value of 0.025

13. REO 018: Top-Line Efficacy Data
o
o
Data announced November 21, 2013
An analysis was performed on an intent-to-treat basis of the 118
patients with loco-regional disease, with or without metastases
o
o
Patients in the test arm (n=62) showed a median PFS of 94 days
(13.4 weeks), versus 50 days (7.1 weeks) in the control arm (n=56)
o
o
At the time of reporting, there had not been a sufficient number of
events to conduct a survival analysis of patients in the metastatic-only
group
Patients who received REOLYSIN® had increased benefit through five
cycles of therapy
Of 88 patients who did not receive additional therapy following
discontinuation of study treatment, those in the test arm (n=50)
showed a median OS of 150 days (21.4 weeks), versus 115 days
(16.4 weeks) in the control arm (n=38)
13
14. REO 018: Top-Line Safety Data
o
o
o
Data announced November 21, 2013 for all 167 patients enrolled
REOLYSIN® was safe and well-tolerated by patients
Patients on the test arm of the study experienced a higher
incidence of flu-like symptoms consistent with earlier clinical trials
of REOLYSIN® and treatment with a virus
o
o
Most commonly mild fever, chills, nausea and diarrhea
Fewer patients required dose reductions of paclitaxel due to
neuropathy or neurotoxicity on the test arm than the control arm
(zero in the test arm versus six in the control; p=0.028)
o
On this basis, Oncolytics intends to explore the potential
chemoprotective and neuroprotective properties of REOLYSIN® in
future clinical studies
14
15. REO 016: Non-Small Cell Lung Cancer
o
o
Single-arm (up to 36 patients), open-label, two-stage US
Phase II study of intravenously-administered REOLYSIN® in
combination with carboplatin and paclitaxel
For non-small cell lung cancer (NSCLC) patients who have
been pre-screened for Kras and EGFR mutation status
o
o
15-20% of NSCLC is Kras mutated, while up to 50% is EGFR mutated or
overexpressed, all of which cause Ras pathway activation
First-line therapy study, i.e. patients will be offered REOLYSIN® /
carboplatin / paclitaxel instead of standard of care if they are Kras or
EGFR mutated or EGFR overexpressed
15
16. REO 016: Biomarker Correlations with
REOLYSIN® Efficacy
o
o
o
o
o
Of 36 evaluable patients, all of whom were Stage IV on
entry, 89% exhibited SD or better (11 PR, 21 SD and 4 PD by
RECIST)
20 of these 36 patients (56%) had one year or more of
survival
Of 24 patients with at least an EGFR mutation or
amplification, 16 (66.7%) had one year or more of survival
Of 13 patients with only an EGFR mutation or amplification,
9 (69.2%) had one year or more of survival
Of 4 patients with BRAF and EGFR amplifications, 4 (100%)
had one year or more of survival
16
18. REO 021: Squamous Cell Carcinoma of
the Lungs
o
o
o
Single-arm (up to 36 patients), open-label US Phase II
study of intravenously-administered REOLYSIN® in
combination with carboplatin and paclitaxel
Final results in 25 evaluable patients (all with
metastatic disease) demonstrated that 92% (23
patients) exhibited overall tumour shrinkage, with
mean shrinkage of 32.7%
Of the 25 evaluable patients who received more than
one cycle of therapy, 10 (40%) showed partial
responses by RECIST, and a further 12 (48%) showed
stable disease by RECIST, for a disease control rate (CR
+ PR + SD) of 92%
