In a range of preclinical models of cancer, including those sensitive and resistant to checkpoint inhibition, VE800 was shown to induce CD8+ T cells, potentiate the immune system’s attack of tumour cells, and significantly amplify the effects of anti-PD-1 therapy.
These models support clinical research to explore whether modulating the microbiome with VE800 has the potential to broaden the efficacy of checkpoint inhibitors.
“Our lead, microbiome-based immuno-oncology candidate, VE800, is based on work conducted in collaboration with our cofounder, Dr Kenya Honda, showing in preclinical models that certain gut-dwelling bacterial strains potentiate cytotoxic CD8+ T cells and enhance infiltration into tumours,” said Bernat Olle, PhD, cofounder and Chief Executive Officer of Vedanta Biosciences.
“Through this collaboration our goal is to determine whether VE800 in combination with Opdivo can improve outcomes for patients with advanced or metastatic cancers.”
“We are continuing to explore the novel mechanisms of new assets in combination with our oncology portfolio,” said Fouad Namouni, MD, Head of Development, Oncology, Bristol-Myers Squibb.
“Vedanta Biosciences is a leading company focused on the characterisation of immunomodulatory human gut commensals and the development of live bacterial products for the potential treatment of human diseases."
"Our collaboration with Vedanta Biosciences will allow us to gain a deeper understanding about the emerging microbiome landscape, its role in oncology, and the potential to improve outcomes for patients with advanced or metastatic cancer.”
“Checkpoint inhibitors, particularly PD-1 antibodies, have been a major advance in cancer therapy; however, a large proportion of patients either do not respond or have response of brief duration to those new therapies,” said Jeffrey Weber, MD, PhD, Deputy Director, Laura and Isaac Perlmutter Cancer Center and Professor of Medicine, NYU Langone Health.
“Alteration of the gut microbiome could play a significant role in enhancing the effectiveness of checkpoint inhibitors, and with increased understanding may also be used to select for patients who would benefit most from these immunotherapies.”
In conjunction with this collaboration, and subject to the completion of due diligence, the negotiation by the parties of definitive transaction agreements and the receipt by Bristol-Myers Squibb of all requisite approvals, Bristol-Myers Squibb currently intends to make an equity investment in Vedanta Biosciences.
Vedanta Biosciences will maintain control of its VE800 programme, including global R&D and commercial rights.
