-- Preliminary data suggest evidence of activity and that the treatment combination was well tolerated --
CALGARY, Dec. 6, 2016 /PRNewswire/ - Oncolytics
Biotech® Inc. ("Oncolytics" or the "Company") (TSX:ONC) (OTCQX:ONCYF) today announced that Dr. Kevin Kelly and colleagues made a poster presentation at the 58th American Society of Hematology
("ASH") Annual Meeting. The poster presentation, titled "Oncolytic Reovirus Immune Priming: A Phase Ib Study of
REOLYSIN® with Bortezomib and Dexamethasone in Patients with Relapsed/Refractory Multiple Myeloma," provides initial
findings from the Company's REO 019 Phase Ib trial. The ASH Annual Meeting runs from December
3rd to 6th in San Diego, CA.
The study is a two-stage open-label Phase Ib trial of adult patients with relapsed or refractory multiple myeloma following at
least one line of therapy. This study was designed to evaluate tolerability, to confirm that the addition of REOLYSIN®
to bortezomib increases endoplasmic reticulum stress and death of myeloma cells (as shown in preclinical models) and to document
pharmacodynamic effects as part of the characterization of the mechanism(s) of action of REOLYSIN® in multiple
myeloma. Kevin Kelly, M.D., Ph.D. of the Keck School of Medicine of the University of Southern California (USC), is the principal investigator.
"The combination of REOLYSIN®, bortezomib and dexamethasone was well-tolerated in these heavily pre-treated
patients, even in those who had been previously exposed to bortezomib," said Dr. Kevin Kelly.
"Preliminary evidence of activity of this combination was documented. It was also shown that the combination therapy induced the
apoptosis of myeloma cells and stimulated the immune system, highlighted by improved cytotoxic T cell infiltration and activation
of checkpoint inhibitors (IDO, PD-L1) in the tumor."
The dose escalation study tested three doses ranging from 3 to 9x1010 TCID50 on days 1, 2, 8, 9, 15 and
16, with 40 mg dexamethasone and 1.5 mg/m2 bortezomib on days 1, 8, and 15. Cycles were repeated every 28 days. A maximum
tolerated dose was not defined because there were no dose-limiting toxicities in the first two cohorts. Cohort 3 is still
enrolling patients. The combination was well tolerated and most treatment emergent toxicities were transient and easily managed
with supportive care. The most common treatment related toxicities were grade 1 diarrhea, grade 1 fatigue, grade 1 flu-like
symptoms and grade 1 headache.
Three patients completed 1 cycle of treatment only, 2 completed 3 cycles, 1 completed 4 cycles and 1 completed 7 cycles. Two
patients remain on protocol (1 has completed 3 cycles (Cohort 3) and the other 7 cycles (Cohort 2)). Six patients were evaluable
for response, 4 patients had stable disease lasting at least 1 cycle, whereas 3 patients had progressive disease at the end of
cycle 1.
"It is intriguing that this combination therapy with REOLYSIN® induced an immune response with mainly grade 1
level toxicity, which is consistent with what we have observed in studies with other REOLYSIN® combinations in
solid tumors," said Dr. Matt Coffey, Interim President and CEO of Oncolytics Biotech. "These data
build on what we have observed in previous studies in both multiple myeloma and solid tumours, and further investigation is
needed to evaluate if the immune modulatory and anti-tumor activity of REOLYSIN® can provide a therapeutic
opportunity to patients with hematological malignancies when combined with other targeted treatments including
immunotherapies."
