First clinical study of a rationally-defined bacterial consortium (VE800) for the treatment of cancer
Company forms Immuno-Oncology Scientific Advisory Board of industry experts to support the clinical development of VE800
Vedanta Biosciences, Inc. (Vedanta Biosciences, Vedanta or the Company), a clinical-stage biopharmaceutical company developing a new category of therapies for immune-mediated diseases based on defined bacterial consortia, today announced the initiation of a first-in-patient clinical study of VE800 in combination with Bristol-Myers Squibb's programmed death-1 (PD-1) immune checkpoint inhibitor Opdivo® (nivolumab) in patients with select types of advanced or metastatic cancer. Vedanta also announced the formation of its Immuno-Oncology Scientific Advisory Board (SAB), which is comprised of experts in immunology, immuno-oncology and the microbiome, to support the planned clinical development of VE800.
The study, which is being conducted at clinical centers in the United States, will evaluate the safety and tolerability and clinical activity of VE800 in combination with Opdivo®, as measured by the confirmed overall response rate, in addition to other parameters. The open-label, non-randomized study will target enrollment of over 100 patients diagnosed with advanced or metastatic melanoma, gastric/gastroesophageal junction adenocarcinoma, or microsatellite-stable colorectal cancer. Eligible patients will receive daily VE800 dosing in combination with Opdivo®. Topline results are anticipated in 2021.
“Despite unprecedented global investment in checkpoint inhibitors, there is still a major need for differentiated approaches to further enhance and expand responses in cancer," said Bernat Olle, Ph.D., co-founder and chief executive officer of Vedanta Biosciences. “The role the gut microbiota plays in influencing responses to immunotherapies has been ignored by previous approaches, so we are excited about the potential of microbiome modulation to open up an entirely new approach to cancer therapy.”
VE800 is made up of 11 commensal bacterial strains that act in concert to activate cytotoxic CD8+ T cells, which are the vanguard of the immune system’s response to tumors and thus a key driver of effective immunotherapies. In preclinical studies, VE800 has been shown to enhance the ability of these T cells to infiltrate tumors, thereby promoting suppression of tumor growth and potentially enhancing survival. Preclinical data also suggest that VE800 may enhance the effects of checkpoint inhibitors.
Foundational work demonstrating VE800’s novel anti-tumor activity and cooperatively potentiated responses to checkpoint inhibitor therapies and various immune challenges was published in Nature by Vedanta and its scientific co-founder Kenya Honda, M.D., Ph.D., of Keio University School of Medicine. The research also showed that mice colonized with VE800 demonstrated enhanced therapeutic efficacy in a range of tumor models when VE800 was administered in conjunction with PD-1 or CTLA4 immune checkpoint inhibitors.
“The ability of bacterial consortia to mediate immune activity, including potential anti-cancer activity, is an exciting area for investigation in indications with some of the highest unmet medical need,” said Hassane M. Zarour, M.D., co-leader of the Cancer Immunology and Immunotherapy Program of the Hillman Cancer Center, University of Pittsburgh, and a member of Vedanta’s newly formed Immuno-Oncology SAB. “We see enormous potential for this class of drugs to improve cancer patients’ outcomes.”
Vedanta’s newly announced Immuno-Oncology SAB will work closely with the Company’s scientific co-founders and leadership to further support the clinical development of VE800. The SAB includes:
About VE800
VE800 is Vedanta Biosciences’ proprietary, orally administered immuno-oncology product candidate. It is produced from pure, non-pathogenic clonal bacterial cell banks, which yield a standardized drug product in powdered form. VE800 consists of a rationally-defined bacterial consortium of 11 commensal strains that, acting in concert, activate cytotoxic CD8+ T cells, a type of white blood cell that is the predominant effector in cancer immunotherapy. In preclinical studies, VE800 has been shown to enhance the ability of these T cells to infiltrate tumors, thereby promoting suppression of tumor growth and enhancing survival. Preclinical data also suggest that VE800 may enhance the effects of checkpoint inhibitors. Vedanta is evaluating VE800 as a potential treatment for patients with advanced or metastatic cancers.
About Vedanta Biosciences
Vedanta Biosciences is a clinical-stage microbiome leader developing a new category of therapies for immune-mediated diseases based on rationally-defined consortia of human microbiome-derived non-pathogenic bacteria. Vedanta’s proprietary capabilities include what is believed to be the largest collection of human-gut associated bacteria, assays and bioinformatics techniques for consortia design and optimization, vast datasets from human interventional studies and facilities for cGMP-compliant manufacturing of rationally-defined bacterial consortia in powder form.
Vedanta Biosciences' pioneering work, in collaboration with its scientific co-founders, has led to the identification of human commensal bacteria that induce a range of immune responses – including induction of regulatory T cells, CD8+ T cells, and Th17 cells, among others. These advances have been published in leading peer-reviewed journals, including Science (multiple), Nature (2013, 2019), Cell, and Nature Immunology. Vedanta Biosciences has harnessed these biological insights and its capabilities to generate a pipeline of investigational live biotherapeutic products (LBPs) in infectious disease, autoimmune disease, allergy, and immuno-oncology. This pipeline includes four clinical-stage product candidates currently being evaluated for the treatment of recurrent C. difficile infection, inflammatory bowel disease (in collaboration with Janssen Biotech, Inc.), food allergy and advanced or metastatic cancers (in combination with Bristol-Myers Squibb’s checkpoint inhibitor Opdivo®), respectively.
Vedanta’s IP portfolio contains over 30 issued patents with coverage through at least 2031. Vedanta Biosciences was founded by PureTech Health (LSE: PRTC). Its scientific co-founders are world-renowned experts in immunology and microbiology who have pioneered the fields of innate immunity, Th17 and regulatory T cell biology.
