BriaCell Therapeutics Corp.

  • BriaCell’s new patent protects its novel personalized off-the-shelf cell-based technology for breast cancer and multiple other cancer indications until 2040.

  • BriaCell expects to initiate its Bria-OTS™ clinical study under an Investigational New Drug Application (IND) in the first half of 2023, in accordance with FDA guidance.

  • Two additional clinical sites are now active in Phase II Bria-IMT™ study to broaden patient access: Carle Cancer Institute in Urbana, Illinois and the American Oncology Network, LLC (AON) in Baltimore, Maryland.

PHILADELPHIA and VANCOUVER, British Columbia, Jan. 10, 2023 (GLOBE NEWSWIRE) — BriaCell Therapeutics Corp. (Nasdaq: BCTX, BCTXW) (TSX: BCT) (“BriaCell” or the “Company”), a clinical-stage biotechnology company specializing in targeted immunotherapies for cancer, is pleased to announce that it has received an Issue Notification from the United States Patent and Trademark Office for the composition of matter and method of use of its personalized off-the-shelf cell-based immunotherapy for cancer. The patent will issue on January 24, 2023 as US Patent No. 11,559,574 with the term extending to May 25, 2040. Additionally, BriaCell was awarded an Australian patent (Patent No. 2017224232, extends to February 27, 2037) covering composition of matter and method of use for its whole-cell cancer immunotherapy technology in Australia .

“We are extremely excited with the new patent for our novel personalized off-the-shelf cancer immunotherapy technology, which provides patent protection for the Bria-OTS™ immunotherapy cell lines under development and further validates and extends our whole-cell cancer immunotherapy technology. This is particularly important because the patent protection is not for one single type of cancer, but rather applies to multiple cancer indications,” stated Dr. William V. Williams, BriaCell’s President and CEO. “Unlike other personalized treatments in the marketplace and under development, our pre-made personalized cancer immunotherapies would allow more rapid treatments and may significantly extend the lives of late-stage cancer patients. We are working diligently to efficiently develop our personalized off-the-shelf immunotherapies for multiple cancers to bring hope to many late-stage cancer patients with no other treatment options.”

Intellectual property: US patent no. 11,559,574, titled “Whole-cell cancer vaccines and methods for selection thereof,” will issue on January 24, 2023, and covers the composition of matter and method of use of BriaCell’s personalized off-the-shelf whole-cell immunotherapies. The novel technology involves the development of several HLA specific whole-cell immunotherapies in advance, and selection of the appropriate off-the-shelf (ie pre-made) immunotherapies for each patient (ie personalized therapy) based on the patient’s HLA type using a fast and easy saliva test. Once issued, the patent will provide intellectual property protection through May 25, 2040, and a patent term extension under Hatch-Waxman potentially applies (which would extend such protection for an additional five years).

Additionally, BriaCell was awarded Australian Patent No. 2017224232, titled “Whole-cell cancer vaccines and methods for selection thereof,” for claims covering composition of matter and method of use for BriaCell’s whole-cell immunotherapy for cancer in Australia.

BriaCell currently holds multiple issued patents and pending patent applications to cover its whole-cell immunotherapy’s composition of matter and method of use worldwide. For a summary of BriaCell’s issued patents, please visit

Bria-OTS™ Program Timelines: FDA has provided guidance regarding the development of cells and final cell-bank testing for BriaCell’s Bria-OTS™ clinical-grade cell lines. Once completed in accordance with FDA’s requirements, BriaCell expects to initiate the Bria-OTS™ study under an Investigational New Drug Application (IND) in the first half of 2023.

Additional Clinical Sites: BriaCell is pleased to announce that it has added Carle Cancer Institute, Urbana, Illinois, and the American Oncology Network, LLC (AON), Baltimore, Maryland, as two additional clinical sites for the screening and enrollment of advanced breast cancer patients in the randomized Phase II study of BriaCell’s lead candidate, Bria-IMT™, with Incyte’s PD-1 inhibitor, retifanlimab.

The following clinical sites are actively enrolling patients for BriaCell’s ongoing Phase II combination study:

  • Carle Cancer Institute, Urbana, Illinois

  • American Oncology Network, LLC (AON), Baltimore, Maryland

  • Mayo Clinic, Jacksonville, Fla

  • Hoag, Newport Beach, California
