Orion Biotechnology Reports Positive Results for Colorectal Cancer in Preclinical Study

Ottawa, Canada [January 15, 2019]:    Orion Biotechnology Canada Ltd., a developer of novel medical treatments,  today announced preclinical data produced in collaboration with Charles River Laboratories, evaluating the efficacy of OB-002O (5P12-RANTES) in colorectal cancer. BALB/c mice were inoculated subcutaneously with the CT-26 colorectal cancer cell line. Three days after inoculation intraperitoneal treatment was started with OB-002O, a murine anti-PD-1 antibody, OB-002 + anti-PD-1, or saline placebo. Treatment was given daily or every third day. Treatment with OB-0020 alone led to statistically significant delayed tumor growth at multiple time-points. An even more profound effect on the decrease in mean tumor volume was observed in combination cohort where animals received both, OB-0020 and the anti-PD-1 antibody (p>0.05).

 “There is growing awareness of the role of CCR5 antagonism as an important component of cancer immunotherapy. OB-002O is an extremely potent CCR5 antagonist and we are delighted to see that OB-002O has robust efficacy alone and in combination with an anti-PD-1 antibody in the CT-26 colorectal cancer model. These data support the further preclinical and clinical development of OB-002O for colorectal cancer” said Dr. Ian McGowan, Chief Scientific Officer for Orion Biotechnology.

Mark Groper, President and CEO of Orion Biotechnology added; “We are delighted by these preliminary data and look forward to the later stage development of OB-002O in colorectal cancer as well as exploring the efficacy of OB-002O in other cancer models.”
