BriaCell 2024 AACR Preclinical Poster Confirms Strong Anti-Cancer Activity of Bria-OTS+™ and Bria-PROS+™ Clinical Candidates for Breast and Prostate Cancer
- None.
- None.
The preclinical findings for BriaCell's Bria-OTS+™ and Bria-PROS+™ suggest a notable advancement in the immunotherapy landscape, particularly in the treatment of breast and prostate cancers. The reported mechanisms, including the activation of various immune cells, could potentially translate into more effective treatments compared to current standards. The broad HLA target range is particularly noteworthy, potentially making these therapies applicable to a wider patient population.
The advancement to GMP manufacturing and the upcoming phase 1/2a clinical studies will be critical milestones. Investors should monitor these developments closely, as positive clinical outcomes could significantly impact BriaCell's valuation and the broader oncology market. However, it is important to remain cautious, as the transition from preclinical to clinical efficacy is often unpredictable and many compounds fail to replicate early success in later-stage trials.
The activation of the immune system's innate and adaptive branches by Bria-OTS+™ and Bria-PROS+™ could represent a significant breakthrough in cancer immunotherapy. Engaging NK cells to counteract cancer immune escape is particularly promising, as it addresses a common mechanism by which tumors avoid immune detection. The personalized aspect of the therapy aligns with the trend towards precision medicine, which aims to tailor treatments to individual patient profiles for improved outcomes.
From a clinical perspective, the anticipated favorable side effect profile and ease of administration could improve patient compliance and quality of life. However, the true test of these therapies will be their performance in human trials. The potential for long-lasting anti-cancer effects would be a major benefit, but these results must be cautiously interpreted until validated in clinical settings.
The immunotherapy sector is highly competitive, with numerous players seeking to develop novel treatments. The unique proposition of BriaCell's platform is its aim to cover nearly 99% of the population, which could disrupt the market if the clinical trials confirm the preclinical promise. The ease of administration could also be a competitive advantage, potentially reducing healthcare costs and improving patient access.
Investors should consider the strategic positioning of BriaCell in relation to its competitors, the scalability of its manufacturing process and the company's ability to navigate the regulatory landscape. The outcome of the upcoming clinical trials will be pivotal in determining the commercial trajectory of Bria-OTS+™ and Bria-PROS+™. Market dynamics, including partnerships, licensing opportunities and the potential for acquisition by larger pharmaceutical companies, should also be factored into the analysis.
- Preclinical data shows that BriaCell’s Bria-OTS+™ and Bria-PROS+™ effectively induce an anti-cancer immune response via multiple mechanisms including naïve helper and killer T cells, dendritic cells, and natural killer (NK) cells
- The novel mechanisms of action may lead to strong anti-cancer activity in breast and prostate cancer patients
PHILADELPHIA and VANCOUVER, British Columbia, April 10, 2024 (GLOBE NEWSWIRE) -- BriaCell Therapeutics Corp. (Nasdaq: BCTX, BCTXW) (TSX: BCT) (“BriaCell” or the “Company”), a clinical-stage biotechnology company that develops novel immunotherapies to transform cancer care, today is pleased to report preclinical data showing strong anti-cancer activity of its next generation, personalized, off-the-shelf, cell-based breast and prostate cancer immunotherapies, Bria-OTS+™ and Bria-PROS+™, in a poster session during the 2024 American Association for Cancer Research (AACR) Annual Meeting held from April 5-10 at San Diego Convention Center, San Diego, CA.
“Our data demonstrates enhancement of immune responses and expanded mechanisms of action of the Bria-OTS+™ platform,” commented Miguel A. Lopez-Lago, PhD, BriaCell’s Chief Scientific Officer. “We anticipate that our novel immunotherapeutic platform will provide potent and long-lasting anti-cancer activity in cancer patients. We view our technology as a significant scientific advancement in the field of oncology and personalized immunotherapy.”
“We are truly thrilled with our data confirming the robust immune system activation elicited by our novel next generation Bria-OTS+™ platform – featuring proprietary immune activating factors for improved efficacy,” commented Dr. William V. Williams, BriaCell’s President and CEO. “We have successfully enhanced antigen presentation activity and cytokine expression while expanding our HLA target range to cover nearly

Title: Bria-OTS+™ immunotherapy platform: Harnessing gene-modified tumor cells to reinvigorate the cancer immunity cycle for precision anti-tumor responses
Abstract Presentation Number: 6753
BriaCell has designed Bria-OTS+™, an immunotherapy platform representing the next generation (enhanced version) of Bria-OTS™, BriaCell’s personalized off-the-shelf (i.e. pre-manufactured and ready for use) immunotherapy for cancer. Bria-OTS+™ immunotherapy expresses multiple immune activating cytokines and co-stimulatory molecules in addition to immune boosting granulocyte-macrophage colony-stimulating factor (GM-CSF). BriaCell expects to use Bria-OTS+™ and Bria-PROS+™ in its upcoming phase 1/2a clinical studies for breast and prostate cancer, respectively. Bria-PROS+™ has already entered GMP manufacturing to generate clinical supplies for the phase 1/2a study. The characteristics of the next generation Bria-OTS+™ immunotherapy platform include the following:
- Bria-OTS+™ and Bria-PROS+™ activate key components of the innate immune system which serves as the body’s first line of defense against cancer
- Bria-OTS+™ and Bria-PROS+™ engage multiple facets of the adaptive immune response. This may result in lasting anti-cancer effects in patients
- Specifically activates Natural Killer (NK) cells to counter cancer immune escape caused by the loss of human leukocyte antigens (HLA)
- Designed for personalized and ready-to-use therapy with long term stability
- Simplified administration process of intradermal inoculations (injection into the skin) allows administration in a physician’s office
- Anticipated to have a favorable side effect profile, indicating good tolerance (based on prior findings with Bria-IMT™)
Given ease of administration, potent, multi-faceted immune system activation, and favorable safety profile, BriaCell expects Bria-OTS+™ and Bria-PROS+™ to deliver significant clinical efficacy and survival benefits in breast cancer and prostate cancer, respectively.
