CALGARY, Sept. 25, 2015 /CNW/ - Oncolytics
Biotech Inc. ("Oncolytics") (TSX:ONC) (NASDAQ:ONCY) today announced that Dr. D.W. Sborov and colleagues
made a poster presentation at the 15th International Myeloma Workshop (IMW). The poster presentation, entitled "Combination
Carfilzomib and the Viral Oncolytic Agent REOLYSIN in Patients with Relapsed Multiple Myeloma: A Pilot Study Investigating
Viral Proliferation," discloses initial findings from a pilot study (NCI-9603) in patients with relapsed or refractory multiple
myeloma treated using the combination of carfilzomib and REOLYSIN . The IMW runs from September 23rd
to 26th in Rome, Italy.
Highlights of the data presented include:
100% of patients (8 of 8) experienced an objective response as measured
by changes in blood monoclonal protein. Of these, 2 patients had a very good partial response (VGPR), 3 patients had a partial
response (PR) and 3 patients had a minor response (MR);
Only one patient has progressed to date and five of eight remain
The combination of carfilzomib and REOLYSIN produced
a significant (p=0.005) increase in caspase-3, a marker associated with apoptotic (programmed) cell death; and
The treatment combination was associated with an increased infiltration
of CD8+ T-cells and the significant (p=0.005) upregulation of PD-L1, suggesting that the addition of a PD-1 or PD-L1 inhibitor
may further optimize the treatment regimen.
"These findings demonstrate that the combination
of carfilzomib and REOLYSIN shows promise in hematological malignancies like multiple myeloma and provide compelling
evidence that such drug combinations promote viral replication and cancer cell death," said Dr. Matt Coffey, Chief Operating
Officer of Oncolytics. "Based on these results, we intend to move into randomized studies in this indication."
The investigators noted that this is the first
time a REOLYSIN -based combination has been tested in relapsed multiple myeloma patients. A previous single-agent
study conducted by the collaborators in this patient population showed that REOLYSIN was well tolerated. The collaborators
and others were noted to have conducted preclinical investigations that demonstrated that the combination of REOLYSIN
and carfilzomib synergistically increased the killing of multiple myeloma cells. This provided the clinical rationale for this
study. In this study, the combination of carfilzomib and REOLYSIN produced a significant (p=0.005) increase in
caspase-3, a marker associated with apoptotic cell death. The researchers also determined that the combination of REOLYSIN
and carfilzomib increases infiltration of CD8+ T-cells and significantly (p=0.005) upregulates PD-L1. The investigators concluded
that these findings necessitate continued investigation, and suggest that the addition of a PD-1 or PD-L1 inhibitor may further
optimize the REOLYSIN and carfilzomib regimen.
"To this point, multiple myeloma has not
responded to checkpoint inhibitor therapy," said Dr. Brad Thompson, President and CEO of Oncolytics. "The combination
of REOLYSIN and carfilzomib upregulates PD-L1 and increases infiltration of CD8+ T-cells, which may make the tumor
sensitive to anti-PD-L1 therapy. The follow-on randomized study we are currently planning is expected to have a patient group treated
with the combination of REOLYSIN , a standard of care chemotherapy, and a checkpoint inhibitor, as well as a patient
group receiving REOLYSIN and a standard of care chemotherapy."
NCI-9603 is a U.S. National Cancer Institute
sponsored single-arm, open-label study of intravenously administered REOLYSIN with dexamethasone and carfilzomib
to patients with relapsed or refractory multiple myeloma. Patients receive treatment on days 1, 2, 8, 9, 15 and 16 of a 28-day
cycle, to be repeated in the absence of disease progression or unacceptable toxicity. Approximately 12 patients will be enrolled
in the study. The primary outcomes include measuring reovirus replication, safety, and tolerability. Secondary outcomes include
examining objective response, duration of response, clinical benefit, progression-free survival, and time to progression. Other
outcomes will include the measurement of immunologic correlative markers.
