BriaCell Therapeutics Corp. (“BriaCell” or the “Company”) (TSXV:BCT) (OTCQB:BCTXF), a clinical-stage biotechnology company specializing in targeted immunotherapy for advanced breast cancer, announces that it has filed a provisional patent application with the U.S. Patent and Trademark Office (USPTO) outlining compositions and methods of developing novel multi-valent decoy receptors for diagnosis and treatment of coronavirus infection.
The patent application, entitled “MULTI-VALENT DECOY RECEPTORS FOR DIAGNOSIS AND/OR TREATMENT OF CORONAVIRUS INFECTION”, describes a platform to generate multi-valent molecular constructs (decoy receptors) that have the potential to prevent coronaviruses including the SARS-CoV-2 virus (the virus that causes Coronavirus Disease 2019 (COVID-19)) from entering (infecting) healthy host cells. Multi-valent constructs described in the patent application are believed to have both therapeutic and diagnostic potential, the latter in the context of determining whether a patient has developed coronavirus-specific antibodies. The Company cautions that these novel therapeutics are still under early-stage research and development and is not making any express or implied claims as to their success in treatment or commercial viability. The patent application seeks protection for, among others, the design of new therapeutics and diagnostics and methods for their use.
BriaCell has recently filed three other provisional patent applications related to treatments for Coronavirus including: (1) genetically engineered whole-cell immunotherapy (2) antibody-based treatment; and (3) antigen-based induction of immune response:
Patent Application 1 (April 14, 2020 press release): Genetically Engineered Whole-Cell Immunotherapy
- “INDUCING IMMUNE RESPONSES BY TRANSFORMING CANCER CELLS INTO ANTIGEN-PRESENTING CELLS”;
- Antigen-presenting cells are the cells that typically start immune responses. BriaCell’s whole-cell immunotherapies are designed to stimulate the immune system to recognize and destroy the patient’s tumors by acting as antigen-presenting cells that turn on cancer cell-recognizing immune cells from the patient.
Patent Application 2 (April 21, 2020 press release): Antibody-Based Approach
- “COMPUTER-GUIDED DESIGN OF ANTIBODIES INCLUDING NEUTRALIZING SARS-CoV-2 BINDING AGENTS”;
- Antibodies designed and selected to neutralize SARS-CoV-2 using computer simulation – envisioned to prevent and treat the life-threatening symptoms of COVID-19;
- BriaCell hypothesizes that antibodies may quickly and specifically recognize the SARS-CoV-2 virus, bind to it, and neutralize it.
Patent Application 3 (May 20, 2020 press release): Antigen-Based Approach
- “MULTI-VALENT IMMUNOSTIMULATORS FOR INFECTIOUS DISEASES, AUTOIMMUNE DISEASES, ALLERGIC DISEASES AND CANCER”;
- Platform to generate multi-valent reagents carrying an antigen (such as an antigen from SARS-CoV-2) and delivering it to immune cells to induce (or dampen) immune responses;
- Anticipated effect is a targeted therapy envisioned to selectively destroy infectious agents or cancer cells with minimal negative effect on normal cells.
The Company cautions that COVID-19 therapeutic development is still under early-stage research and development and is not making any express or implied claims that it has the ability to treat, prevent or eliminate the COVID-19 virus at this time. The Company notes that it will be relying on third parties for part of this research.
The Company’s scientific experts have read and approved the scientific disclosures contained in the press release.
BriaCell is an immuno-oncology focused biotechnology company developing targeted and effective approaches for the management of cancer.
