PureTech Health plc (LSE: PRTC) ("PureTech" or the "Company"), a clinical-stage biotherapeutics company dedicated to discovering, developing and commercialising highly differentiated medicines for devastating diseases, is pleased to note that its Founded Entity, Vedanta Biosciences, today announced positive topline data from two Phase 1 studies in healthy volunteers of VE202, the company's orally-administered live biotherapeutic product (LBP) candidate for inflammatory bowel disease (IBD). The studies showed that VE202 was generally safe and well-tolerated at all doses and demonstrated durable and dose-dependent colonisation. Vedanta expects to begin a Phase 2 study in IBD patients in the next 12 months. The trial was conducted by Janssen Research & Development, LLC; a more complete study dataset and analyses will be submitted to a peer-reviewed journal. Vedanta has regained full rights to the IBD programme and will owe Janssen single-digit royalty payments on net sales of a commercialised product.
Vedanta also announced the receipt of $12 million in additional capital and R&D collaboration funds from new and existing investors, including JSR Corporation, bringing the total Series C/C-2 funding to $71.1 million. Participants in the total Series C round included the Bill & Melinda Gates Foundation, Bristol Myers Squibb, Rock Springs Capital, JSR Corporation, Shumway Capital, Health for Life (Seventure Partners), QUAD Investment Management, SV Investment Corp., Shinhan Investment-Private Equity, Shinhan Capital-Yeollim Partners, Partners Investment Co., Ltd, FC Capital, SymBiosis LLC, and founder PureTech.
Bharatt Chowira, JD, PhD, PureTech's president and chief of business and strategy, said: "Vedanta has built an impressive body of evidence that its live biotherapeutic product candidates are safe, well-tolerated and able to modulate the human microbiome in a highly targeted and durable fashion, opening the door for an exciting and entirely novel class of therapeutics. These trial results and the additional Series C funding from leading investors are important milestones for Vedanta and we look forward to the launch of the Phase 2 trial in IBD patients and other advances across the breadth of Vedanta's pipeline of compelling programmes."

CAMBRIDGE, Mass., June 9, 2020 - Vedanta Biosciences , a clinical-stage company developing a new category of therapies for immune-mediated diseases based on rationally-defined consortia of human microbiome-derived bacteria, today announced positive topline data from two Phase 1 studies in healthy volunteers of VE202, the company's orally-administered live biotherapeutic product (LBP) candidate for inflammatory bowel disease (IBD). The studies showed that VE202 was generally safe and well tolerated at all doses and demonstrated durable and dose-dependent colonisation. Vedanta expects to begin a Phase 2 study in IBD patients in the next 12 months. Vedanta also announced the receipt of $12 million in additional capital and R&D collaboration funds from new and existing investors, including JSR Corporation, bringing the total Series C/C-2 funding to $71.1 million. Vedanta's pipeline includes four clinical-stage product candidates currently being evaluated for the treatment of high-risk C. difficile infection, IBD, food allergy and advanced or metastatic cancers (in combination with Bristol Myers Squibb's checkpoint inhibitor Opdivo®).
"We have now seen across three Phase 1 studies for VE202 and VE303, which collectively recruited 143 volunteers, that our LBPs appear to be safe and have the intended effect of robustly and durably colonising and changing the gut microbiome composition in a targeted manner," said Bernat Olle, PhD, chief executive officer of Vedanta Biosciences. "Current treatments for IBD block mediators of inflammation, but do not address the underlying alterations in the gut microbiota that may be driving the inflammation in the first place. There is significant evidence of the role of the microbiome in IBD, which underscores the need for safe approaches that address this aspect of the disease."
The Phase 1 studies of VE202 enrolled 105 healthy volunteers in single and multi-dose cohorts, and evaluated two variants of VE202, with either 11 or 16 bacterial strains forming the consortia. These consortia include several species of bacteria belonging to Clostridium Clusters IV and XIVa, which have been previously shown to play a role in induction of tolerance in IBD and are associated with disease remission. Preliminary data include:
· Both single and multiple doses of the 11- and 16-strain consortia were generally safe and well-tolerated. There were no serious adverse events related to VE202.
· Both consortia variants colonised the gut abundantly. Colonisation was most effective with vancomycin pre-treatment followed by multiple doses of the consortia. In subjects who were dosed for 14 days, VE202 strains were detected at high abundances 12 weeks after dosing ended, suggesting substantial durability of colonisation.
The trial was conducted by Janssen Research & Development, LLC; a more complete study dataset and analyses will be submitted to a peer-reviewed journal.
Vedanta has regained full rights to the programme and will owe Janssen single-digit royalty payments on net sales of a commercialised product. Vedanta plans to take the programme forward into Phase 2 studies over the next 12 months.
Additionally, the European Patent Office (EPO) recently granted Vedanta Biosciences three patents in its foundational intellectual property (IP) family covering the use of bacterial consortia of clostridium species in autoimmune diseases, including IBD. The patent issuances follow the 2019 decision of the Opposition Division of the EPO to uphold Vedanta's foundational patent EP2575835 (the "Honda patent"), strengthening Vedanta's IP position in the area of live bacterial therapeutics.
About VE202
VE202 is a first-in-class orally-administered investigational live biotherapeutic product (LBP) consisting of a defined bacterial consortium. It is produced under GMP conditions from pure, clonal bacterial cell banks, which yield a standardised drug product in powdered form and bypasses the need to rely on direct sourcing of faecal donor material of inconsistent composition. VE202 was designed to induce immune tolerance via the gut and thereby potentially treat inflammatory bowel disease. Results describing the biology and candidate selection of VE202 were previously published in Science and Nature ( multiple ).
