Oncolytics Biotech® Announces Publication of Preclinical and Patient Data Demonstrating Pelareorep's Stimulation of Natural Killer Cell Anti-Cancer Activity
Oncolytics Biotech Inc. (NASDAQ: ONCY) announced the publication of preclinical and patient data on pelareorep in Immunology. The study highlights pelareorep's effects on Natural Killer (NK) cells and their activation, which is crucial for anti-cancer immunity. Results showed enhanced NK cell activity in patients with colorectal liver metastases after pelareorep treatment, mediated by type 1 interferon signaling. Going forward, Oncolytics aims to leverage these findings to further develop pelareorep in oncology, particularly for breast cancer and other indications.
- Published in a peer-reviewed journal, boosting credibility.
- Pelareorep demonstrated activation of NK cells, enhancing anti-cancer immunity.
- Positive patient outcomes observed in colorectal liver metastases.
- Forward-looking statements indicate uncertainty and risks in clinical studies and commercialization.
SAN DIEGO and CALGARY, AB, March 17, 2022 /PRNewswire/ -- Oncolytics Biotech® Inc. (NASDAQ: ONCY) (TSX: ONC) today announced the publication of preclinical and patient data on pelareorep in the peer-reviewed journal Immunology. The paper, entitled "Oncolytic virus treatment differentially affects the CD56dim and CD56bright NK cell subsets in vivo and regulates a spectrum of human NK cell activity," was published in collaboration with researchers at several prestigious institutions, including the University of Leeds School of Medicine and the Institute of Cancer Research, London. A link to the paper can be found by clicking here.
Described in the paper are in vitro studies evaluating pelareorep's effects on Natural Killer (NK) cells as well as analyses of blood samples from patients with colorectal liver metastases taken prior to and after treatment with pelareorep. Results showed pelareorep treatment led to the activation of NK cells, which are known to directly kill cancer cells while stimulating adaptive anti-tumor immunity. The beneficial effects of pelareorep were observed both in patient samples and in vitro and were mediated by type 1 interferon (IFN-1) signaling, a key pathway involved in immunoregulation and tumor cell recognition.
"These important results further demonstrate both pelareorep's innate and adaptive immunologic mechanism of action, and we are pleased to have them published in such a prestigious, peer-reviewed journal," said Dr. Matt Coffey, President and Chief Executive Officer of Oncolytics Biotech and co-author of the paper. "When viewing these findings, alongside prior clinical data demonstrating pelareorep's ability to activate T cells while promoting their infiltration into tumors, we see pelareorep delivering a robust, coordinated anti-cancer immune response driven by both the innate and adaptive immune systems. Looking forward, we will continue to leverage the immunotherapeutic effects of pelareorep as we further its development as an enabling technology for a wide cross-section of immunotherapeutic agents in breast cancer and other oncologic indications with high unmet needs."
Patient samples evaluated in the publication were from a completed window-of-opportunity clinical study evaluating pelareorep in colorectal cancer patients with liver metastases. Patients received between one and five doses of pelareorep prior to planned surgery to resect metastases. Blood samples were taken both prior to and at multiple time points after pelareorep treatment. Additional details of the trial, as well as previously reported results, are available in prior peer-reviewed publications1,2.

About Oncolytics Biotech Inc.
Oncolytics is a biotechnology company developing pelareorep, an intravenously delivered immunotherapeutic agent. This compound induces anti-cancer immune responses and promotes an inflamed tumor phenotype -- turning "cold" tumors "hot" -- through innate and adaptive immune responses to treat a variety of cancers.
Pelareorep has demonstrated synergies with immune checkpoint inhibitors and may also be synergistic with other approved oncology treatments. Oncolytics is currently conducting and planning clinical trials evaluating pelareorep in combination with checkpoint inhibitors and targeted therapies in solid and hematological malignancies as it advances towards a registration study in metastatic breast cancer.
