BERKELEY, Calif. and VANCOUVER, British Columbia, Jan. 13, 2020 (GLOBE NEWSWIRE) -- BriaCell Therapeutics Corp. ("BriaCell" or the "Company") (TSX-V:BCT) (OTCQB:BCTXD), a clinical-stage biotechnology company specializing in targeted immunotherapy for advanced breast cancer, is pleased to provide an update on the previously-announced (Link) top responder (“Remarkable Responder”) in the combination study of its lead candidate, Bria-IMT™, with Incyte’s INCMGA00012, a PD-1 inhibitor.
The patient, who had experienced notable tumor shrinkage while on treatment with Bria-IMT™ in combination with the PD-1 inhibitor pembrolizumab [KEYTRUDA®; manufactured by Merck & Co., Inc. (NYSE: MRK)], has since transitioned to treatment in combination with INCMGA00012. On this combination treatment, the patient has had a subsequent further remarkable reduction in a breast cancer tumor behind the left eye in the left orbital region. This tumor, which had pushed the eye forward from the skull (known as proptosis), has resolved following 3 months of treatment. The tumor had shrunk by 19% during treatment with the Bria-IMT™ regimen in combination with KEYTRUDA®, and has now completely disappeared during treatment in combination INCMGA00012. While not all of the patient’s tumors have resolved, the proptosis and associated eye problem have been resolved.
BriaCell’s “matching hypothesis” has been further strengthened: The Remarkable Responder matched Bria-IMT™ at 2 HLA loci (HLA-C and HLA-DRB3). BriaCell’s immunotherapy treatment appears most effective when the patient’s HLA-type matches the Bria-IMT™ HLA-type as concluded in prior Phase IIa proof-of-concept work.
“The complete regression of a tumor this large and this advanced, in a patient resistant to 16 previous treatment regimens, is unprecedented in my 50 years of clinical practice,” said Dr. Charles Wiseman, BriaCell’s Scientific Founder and Director. “These very important positive clinical observations support BriaCell’s strategy to continue investigating the combination regimen of Bria-IMT™ with checkpoint inhibitors, and may lead to a new treatment option for breast cancer patients suffering advanced, resistant disease.”
