5. REOLYSIN® Mechanism of Action
REOLYSIN®
infects both
tumour cells
and normal
healthy cells
REOLYSIN®
does not
replicate in
cells that are
not Ras
activated
Healthy cells
remain
undamagedREOLYSIN®
Administered to
patients
PRE-SCREENED
for RAS, EGFR,
BRAF and others
Normal Cells
REOLYSIN®
infects both
tumour cells
and normal
healthy cells
REOLYSIN®
replicates in
Ras-activated
tumour cells
Tumour cells then
rupture to release
progeny virus
Progeny viruses repeat cell
infection cycle in nearby
tumour cells
Ras–Activated Cells
Productively infected cells upregulate interferon and
others, including PD-1 and PD-L1, and induce an anti-
tumour specific immune response mediated by NK and
T cells

13. REO 018 Head and Neck Cancer: Randomized
Tumour-Specific Response Data
First Endpoint: Velocity
o 105 patients
o 86% of test arm (n=50) had
tumour stabilization or shrinkage
o 67% of control arm (n=55) had
tumour stabilization or shrinkage
o p-value 0.025
Second Endpoint: Volume
Loco-regional patients with or without
distal metastases
o 23% improvement in test arm vs.
control for tumour volume decrease
o p-value 0.076, n=118
Patients with distal metastases only
o 30% improvement in test arm vs.
control for tumour volume decrease
o p-value 0.021, n=47
Study demonstrated that REOLYSIN® increased both the
magnitude and velocity of tumour shrinkage
13

14. Registration Program for REOLYSIN®
Short-Term: Tumour Reduction Endpoints:
Neoadjuvant treatment of muscle-invasive bladder cancer
Neoadjuvant = therapy used prior to a major therapeutic intervention
(usually surgery) in order to improve outcome
Next Steps:
IND has been filed to conduct a small “run-in” study assessing
histopathological response in muscle invasive bladder cancer
o REOLYSIN® in combination with gemcitabine and cisplatin
Subject to confirmation of response – proceed to pivotal trial
14

15. Studies demonstrate that REOLYSIN® increases both the
magnitude and velocity of tumor shrinkage
Muscle invasive bladder cancer is the only cancer indication in
which US regulators have accepted histopathological response
as a registration endpoint in a neoadjuvant study to date
Each patient enrolled in the study will be assessable for this
endpoint at a maximum of nine weeks after starting
treatment
15
Why Muscle Invasive Bladder Cancer?

16. What Does
REOLYSIN® Do?
Improves Overall Survival

17. Top-Line Overall Survival (OS) Results:
REO 018 (Head and Neck Cancer)
An intent-to-treat analysis of 118 patients with loco-
regional disease showed a statistically significant
improvement in the OS of the test arm versus that of
the control arm1
p=0.0146
hazard ratio=0.5099
1
Overall survival was measured to the median PFS in each arm, censoring any patients who received
post-discontinuation therapy from the date on which they commenced the first of these therapies.

19. What Does
REOLYSIN® Do?
Enhances Long-Term
Immune Responses

20. Days Post Treatment:

20

21. REOLYSIN®: Enhancing Immune Response
REOLYSIN® acts as a selective cytotoxin – killing the
tumour cells in which it replicates
We now know that administration of REOLYSIN®
also:
Causes the immune system to recognize
and kill tumour cells as well
Causes up-regulation of PD-1 and PD-L1
21

22. REOLYSIN®: Immunology & Anti-PD-1 / PD-L1
In some types of cancer (including pancreatic
cancer, glioblastoma and metastatic brain
lesions), REOLYSIN® has been shown to
upregulate PD-1 and PD-L1 (Appendix A)
In cancers with low PD-1 and PD-L1 upregulation,
this enhances the activity of checkpoint inhibitors
22

23. Immune Preclinical Research
In ovarian cancer models in mice:
Combination of gemcitabine and reovirus type 3 improved
overall survival
In melanoma models in mice:
Combination of GM-CSF with REOLYSIN® improved overall
survival
In brain cancer models in mice:
Combination of a checkpoint inhibitor (anti-PD-1) with
REOLYSIN® improved overall survival
23

24. Enhancing Immune Responses to
Improve Overall Survival
Ongoing preclinical and clinical research has led to
three clinical programs:
1. Gemcitabine in combination with REOLYSIN® (REO 009
and REO 017);
2. GM-CSF in combination with REOLYSIN® (Mayo
(pediatric) and Leeds (adult)); or
3. Checkpoint inhibitors in combination with REOLYSIN®
(studies pending)
24

25. Registration Program for REOLYSIN®
Medium-Term: intravenous treatment of advanced
gliomas
Long-Term: to be determined upon receipt of data
from ongoing single-arm and randomized studies in a
range of indications
25

26. Medium-Term – Overall Survival Endpoints
A key finding from REO 013 was that REOLYSIN® can cross the blood brain barrier
and subsequently infect and kill tumour in the brain, as well as primary gliomas and
metastatic lesions from other primary cancers outside brain
We have completed and initiated four studies of REOLYSIN® in glioma patients:
26
• REO 003 – Ph 1/2 local mono-therapy
• REO 007 – Phase 1/2 infusion mono-
therapy
• REO 013 – Ph 1 IV prior to surgical resection
• MC1472 – Ph 1 IV combined with GM-CSF -
pediatric (ongoing)

Next Steps
A small “run-in” study assessing response in gliomas has been initiated
(Mayo Clinic’s MC1472)
o Pediatric patients being treated with REOLYSIN® in combination with GM-CSF
Second study assessing response in adult patients receiving REOLYSIN® and
the standard of care (surgery followed by radiation and temozolomide)
Subject to confirmation of best approach – proceed to pivotal trial
