Orion reports positive results for OB-002O
OTTAWA—Orion Biotechnology Canada Ltd. recently announced preclinical data produced in collaboration with Charles River Laboratories evaluating the efficacy of OB-002O (5P12-RANTES) in colorectal cancer.
In the research, 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-002O + 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-002O 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.
Added Mark Groper, president and CEO of Orion Biotechnology: “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.”
