Dr. William Williams, BriaCell’s President & CEO, called in to SmallCapVoice.com, Inc. to discuss BriaCell Therapeutics Corp.’s history, management, advisory board, Bria-IMT™ (SV-BR-1-GM), the Company’s lead product candidate as a targeted and safe approach to the management of cancer, and more. Recently, the Company announced the acceptance of a manuscript describing the novel mechanism of action of the Company’s lead product candidate, Bria-IMT™. The findings detailed in the paper provide a rationale for the encouraging clinical results observed with Bria-IMT™ in current and past clinical testing. The publication will appear in Frontiers in Immunology, the 5th most cited journal in Immunology worldwide. Bria-IMT™, also known as SV-BR-1-GM, has caused remarkable reduction of tumor size in some patients with advanced metastatic breast cancer.
BriaCell is an immuno-oncology focused biotechnology company developing a targeted and safe approach to the management of cancer. Immunotherapy has come to the forefront in the fight against cancer, harnessing the body’s own immune system in recognizing and selectively destroying cancer cells while sparing normal ones. Immunotherapy, in addition to generally being more targeted and less toxic than commonly used types of chemotherapy, is also thought to be a potent approach with the potential to prevent cancer recurrence.
Bria-IMT™ (SV-BR-1-GM), the Company’s lead product candidate, is derived from a specific breast cancer cell line. It is genetically engineered to release granulocyte-macrophage colony-stimulating factor (GM-CSF), a substance that activates the immune system. We believe that Bria-IMT™ helps the body to recognize and kill tumor cells by activating T cells that attack the tumor and B cells that produce anti-tumor antibodies.
The results of two previous proof-of-concept clinical trials (one with the precursor cell line not genetically engineered to produce GM-CSF and one with Bria-IMT™) produced encouraging results in patients with advanced breast cancer. Most notably, one patient with metastatic breast cancer responded to Bria-IMT™ with substantial reduction in tumor burden including breast, lung, soft tissue and brain metastases. BriaCell is currently conducting a Phase I/IIa clinical trial for Bria-IMT™ in patients with advanced breast cancer. In this trial, Bria-IMT™ treatment appeared safe with similar instances of tumor reduction as those observed in the earlier proof-of-concept trials. This trial is listed in ClinicalTrials.gov as NCT03066947. The trial is being conducted along with the co-development of BriaDX™, the Company’s companion diagnostic test. Additionally, the FDA recently approved the roll-over combination study of Bria-IMT™ with pembrolizumab [Keytruda; manufactured by Merck & Co., Inc.] or ipilimumab [Yervoy; manufactured by Bristol-Myers Squibb Company] for patients previously treated with Bria-IMT™ in the Company’s ongoing Phase I/IIa clinical trial in advanced breast cancer. The roll-over trial is listed in ClinicalTrials.gov as NCT03328026.
BriaCell is also developing Bria-OTS™, an off-the-shelf personalized Immunotherapy. Bria-OTS™ is a set of cell lines similar to Bria-IMT™ which are being engineered to express pre-manufactured HLA alleles. With a combined total of 15 different alleles Bria-OTS™ is expected to be able to match more than 90% of the US population. BriaCell’s BriaDX™ companion diagnostic reveals patient HLA types. One or two Bria-OTS™ cell lines carrying matching alleles are planned to be administered per patient. Bria-OTS™ eliminates the complex manufacturing logistics required for other personalized immunotherapies and is regarded as a personalized therapy without the need for personalized manufacturing.
Yet another item in the BriaCell pipeline is a novel, selective protein kinase C delta (PKCδ) inhibitor. PKCδ inhibitors have shown activity in a number of pre-clinical models of RAS genes’ transformed cancers including breast, pancreatic, non-small cell lung cancer and neuroendocrine tumors (such as carcinoid tumors).
