Aion Therapeutic's Proprietary Mushroom Preparations Shown Effective in Killing Breast Cancer Cells

TORONTO, April 21, 2021 /PRNewswire/ - Aion Therapeutic Inc. (CSE: AION) ("Aion Therapeutic" or the "Company") announced today that its proprietary and patented combinatorial mushroom preparations AION F7 and AION F8 (collectively, the "Aion Mushroom Preparations" or "Preparations") showed high efficacy in killing HER2+ breast cancer cells, ER+/PR+ breast cancer cells, and triple-negative breast cancer cells by direct cytotoxicity.

As shown in recently completed third-party independent and carefully controlled 3D-spheroid cell culture studies performed at BIOENSIS laboratories, these cytotoxicity studies demonstrated direct killing of the breast cancer cells by the Aion Mushroom Preparations, which suggests such preparations may be effective in treating HER2+ breast cancer, ER+/PR+ breast cancer, and the very difficult to treat triple-negative breast cancer, with each of these types of breast cancers tested independently.

In separate independent studies at BIOENSIS laboratories using the Antibody-Dependent Cellular Cytotoxicity (ADCC) assay and the Antibody-Dependent Cellular Phagocytosis (ADCP) assay, the Aion Mushroom Preparations also demonstrated enhanced cell killing of HER2+ breast cancer cells via stimulation of the immune system. The Preparations showed similar effectiveness as trastuzumab, a monoclonal antibody treatment sold under the brand name Herceptin, manufactured by Roche and is a US FDA approved medication useful for treating HER2+ breast cancer that is either early-stage or advanced-stage/metastatic. Herceptin (trastuzumab) is the leading breast cancer drug with annual global sales of around $7 billion.¹ Other FDA approved biosimilar trastuzumab products include: Trazimera (Pfizer), Kanjinti (Amgen), Ontruzant (Merck), Herzuma (Teva), and Ogivri (Mylan). When Aion Mushroom Preparations were combined with Trastuzumab, there was a greater than 60% increase in the killing of HER2+ breast cancer cells when compared to Trastuzumab used alone.

Based on these results, Dr. Herbert A. Fritsche, Chief Science Officer of Aion Therapeutic and former Professor and Director of Clinical Chemistry at the University of Texas, MD Anderson Cancer Center, stated, "The extremely exciting results obtained from these independent 3D cell culture studies suggests that when appropriate Aion Mushroom Preparations are used together, they may offer a dual approach to the killing of HER2+ breast cancer cells through two separate and distinct pathways (direct cytotoxicity and antibody dependent cytotoxicity). The significant improvement in cancer cell cytotoxicity that was observed when the Preparations were combined with Trastuzumab warrants immediate further investigation in breast cancer patients." Dr. Fritsche continued, "We look forward to the next step of initiating clinical trials of the Aion Mushroom Preparations with and without Herceptin (and other trastuzumab biosimilars) for the treatment of HER2+ breast cancer patients as well as the Aion Mushroom Preparations alone in ER+/PR+ breast cancer and triple-negative breast cancer patients."

"Each year more than 1.6 million new cases of breast cancer are diagnosed globally, making it the most common cancer among women, and more than 500,000 women will die of the disease," said Graham Simmonds, Executive Vice Chair and CEO of Aion Therapeutic. He added, "We are excited that these Aion Mushroom Preparations that have shown very encouraging initial test results will be developed to be transformative in how women are treated globally."
