PureTech Founded Entity Vedanta Biosciences Announces Phase 2 Study of VE202 in Ulcerative Colitis Did Not Meet Primary Endpoint

BOSTON--(BUSINESS WIRE)-- PureTech Health plc (Nasdaq: PRTC, LSE: PRTC) ("PureTech"), noted that its Founded Entity, Vedanta Biosciences, ('Vedanta') a late clinical-stage biopharmaceutical company developing microbiome-based oral therapies for gastrointestinal diseases, today announced that its candidate VE202 did not meet the primary endpoint in the Phase 2 COLLECTiVE202 study for the treatment of patients with mild-to-moderate ulcerative colitis (UC). Vedanta remains focused on advancing its lead program, VE303, for the prevention of recurrent Clostridioides difficile infection (CDI). Ulcerative colitis and CDI are distinct diseases with different underlying biology, and VE202 and VE303 have different bacterial compositions and mechanisms of action. VE303 has demonstrated positive Phase 2 results, reducing CDI recurrence risk by more than 30% compared with placebo, and is currently being evaluated in the global, registrational Phase 3 RESTORATiVE303 study. The program has received both Fast Track and Orphan Drug designations from the FDA and, if approved, is positioned to become the first live biotherapeutic product for any indication. Vedanta is also advancing VE707, designed to prevent infections caused by multidrug-resistant organisms, with an IND submission planned for 2026. Over the course of 2025, PureTech's ownership stake in Vedanta has been diluted to 4.2% on a fully diluted basis. The full text of the announcement from Vedanta is as follows: Vedanta Biosciences Announces Phase 2 Study of VE202 in Ulcerative Colitis Did Not Meet Primary Endpoint VE202 was well tolerated, with no reports of treatment-related serious adverse events Additional analyses from COLLECTiVE202 to be shared in upcoming scientific forums Vedanta to focus resources on ongoing Phase 3 RESTORATiVE303 registrational study of VE303 in recurrent Clostridioides difficile infection – Vedanta Biosciences, a late clinical-stage biopharmaceutical company developing microbiome-based oral therapies for gastrointestinal diseases, today announced that its candidate VE202 did not meet the primary endpoint of endoscopic response in the Phase 2 COLLECTiVE202 study for the treatment of patients with mild-to-moderate ulcerative colitis (UC). 'We are very disappointed that our study did not meet its efficacy endpoints, and our greatest regret is that people living with inflammatory bowel disease will not, for now, have the opportunity to benefit from a new treatment option,' said Bernat Olle, Ph.D., Chief Executive Officer of Vedanta Biosciences. 'The gut microbiome is a well-recognized driver of IBD, yet remains a facet of the disease untouched by current treatments. As a field, we have not yet succeeded in making a meaningful impact for people with IBD through microbiome-based approaches, but every study moves us closer to that goal. We are committed to sharing further analyses of this study at upcoming scientific meetings to help chart new paths forward. 'Our priority at Vedanta remains the successful execution of our ongoing global pivotal study of VE303 for the prevention of recurrent C. difficile infection, with the goal of potentially delivering the first approved Live Biotherapeutic Product in any indication — and, in doing so, addressing a serious health condition with a significant unmet medical need,' concluded Dr. Olle. In the randomized, placebo-controlled COLLECTiVE202 study, endoscopic and clinical responses were assessed using standardized criteria, and the observed response rates in the VE202 group were not statistically different from those in the placebo group. VE202 was generally safe and well tolerated — most adverse events were mild or moderate in intensity, with no reports of treatment-related serious adverse events. Analyses of bacterial colonization, histological findings, and immune responses are ongoing and will be shared in future scientific forums. Vedanta remains focused on advancing its other pipeline programs: VE303: Vedanta is currently enrolling patients into RESTORATiVE303, a registrational Phase 3 study of VE303 for the prevention of recurrent C. difficile infection (rCDI) at over 200 sites in 24 countries. The Phase 3 program is supported by results from a positive Phase 2 study, in which VE303 demonstrated potentially best-in-disease efficacy with a 30.5% absolute risk reduction compared with placebo and greater than 80% reduction in the odds of a CDI recurrence. VE707: Vedanta is also advancing VE707 to prevent infections by multidrug-resistant organisms that affect a wide range of vulnerable populations in areas such as oncology, urology, transplantation, and critical care, with IND submission planned for 1H 2026. About the COLLECTiVE202 Study COLLECTiVE202 is a double-blind, placebo-controlled, randomized clinical trial conducted at sites in the United States, Europe, and Australia. The study enrolled 114 patients, between the ages of 18 and 75 years, with mild-to-moderate ulcerative colitis who had not been exposed to any biologic or advanced oral therapies. Either VE202 (N=57) or placebo (N=57) was added to a patient's stable background ulcerative colitis therapy. The primary endpoints were safety and Week 8 endoscopic response (defined as a reduction of at least 1 point on the Mayo endoscopic subscore). Secondary endpoints included clinical response and remission, endoscopic improvement and remission, as well as histological assessments and measures of colonization, quality-of-life and inflammatory biomarkers.

PureTech Founded Vedanta Biosciences Publishes Additional Phase 2 VE303 Results in Nature Medicine

PureTech Health plc (Nasdaq: PRTC, LSE: PRTC) ('PureTech' or the 'Company'), a clinical-stage biotherapeutics company dedicated to changing the lives of patients with devastating diseases, noted that its Founded Entity, Vedanta Biosciences, a late clinical-stage company developing defined bacterial consortia as oral therapies for gastrointestinal diseases, today announced the publication of additional results from the Phase 2 CONSORTIUM study for its lead candidate, VE303, which is being evaluated for prevention of recurrent Clostridioides difficile infection (rCDI). The new analyses were published this month in Nature Medicine and can be viewed online. VE303 is a potential first-in-class Live Biotherapeutic Product for the prevention of rCDI, which consists of a defined consortium of eight bacterial strains. Clinical results from Vedanta's successful Phase 2 CONSORTIUM study, published in the Journal of the American Medical Association (JAMA), demonstrated that the higher dose of VE303 studied was well tolerated and reduced the odds of CDI recurrence by more than 80% compared with placebo. The new publication which is entitled 'Multi-omic Profiling a Defined Bacterial Consortium for Treatment of Recurrent Clostridioides difficile Infection,' reports additional results from CONSORTIUM. Profiling of microbiome composition, fecal metabolites, and host immune function indicated that VE303 works through multiple mechanisms to prevent rCDI by restoring a healthy gut microbial community, decreasing inflammation, and increasing levels of protective metabolites. In addition, the work identified predictors of high or low VE303 colonization and clinical response. Taken together, these results demonstrate that VE303 works through multiple mechanisms to reduce CDI recurrence. Results from the CONSORTIUM study informed the design and dose selection for the global, pivotal Phase 3 study, RESTORATiVE303, that is currently underway to confirm the efficacy and safety profile of VE303 in the prevention of rCDI. Topline data for this study are expected in 2026. The full text of the announcement from Vedanta is as follows: Vedanta Biosciences Publishes Additional Phase 2 VE303 Results in Nature Medicine VE303 was well tolerated and decreased the odds of rCDI through multiple mechanisms Analyses identified predictors of VE303 colonization and protection from CDI recurrence Topline data for the ongoing Phase 3 pivotal RESTORATiVE303 study are expected in 2026 CAMBRIDGE, Mass., January 23, 2025 -- Vedanta Biosciences, a late clinical-stage company developing defined bacterial consortia as oral therapies for gastrointestinal diseases, today announced the publication of additional results from the Phase 2 CONSORTIUM study for its lead candidate, VE303, which is being evaluated for prevention of recurrent Clostridioides difficile infection (rCDI). The new analyses were published this month in Nature Medicine and can be viewed online. VE303 is a potential first-in-class Live Biotherapeutic Product for the prevention of rCDI, which consists of a defined consortium of eight bacterial strains. Clinical results from Vedanta's successful Phase 2 CONSORTIUM study, published in the Journal of the American Medical Association (JAMA), demonstrated that the higher dose of VE303 studied was well tolerated and reduced the odds of CDI recurrence by more than 80% compared with placebo. VE303 organisms rapidly and robustly colonize the gut in a dose-dependent manner. Colonization predicted greater recurrence-free probability, establishing a direct connection between exposure and clinical response. The publication which is entitled 'Multi-omic Profiling a Defined Bacterial Consortium for Treatment of Recurrent Clostridioides difficile Infection,' reports additional results from CONSORTIUM. Profiling of microbiome composition, fecal metabolites, and host immune function indicated that VE303 works through multiple mechanisms to prevent rCDI by restoring a healthy gut microbial community, decreasing inflammation, and increasing levels of protective metabolites. In addition, the work identified predictors of high or low VE303 colonization and clinical response. 'This clinical research offers new insights into the mechanisms of action of VE303, providing a rationale for the drug's protective effects in rCDI,' said Bernat Olle, Ph.D., Chief Executive Officer of Vedanta Biosciences. 'Due to VE303's precisely known, defined composition, we can study its mechanisms of action and PK-PD relationships in a rigorous way, taking a step towards understanding why some patients respond better than others to a microbiome restoration intervention. We believe this line of work helps fill a knowledge gap in the field, since characterization of the mechanisms of action of first-generation fecal microbiota products has been very limited.' Highlights of the publication include: Abundance of specific VE303 strains, and of VE303 strains overall, was predictive of remaining recurrence-free. The strains that colonized well differed across individuals, suggesting that efficacy is derived from strains working together as a consortium. VE303 colonization and clinical benefit correlated with increased levels of short-chain fatty acids and key secondary bile acids, both of which have beneficial effects in conferring resistance to CDI. Faster recovery of a more diverse microbiome, which was seen in the high dose recipients of VE303, was associated with non-recurrence. The elimination rate of the antibiotic used for the CDI episode was a predictor of VE303 colonization. Given that clearance of residual antibiotic from stool varies significantly among individuals and can take a week or longer, treating with VE303 for 14 consecutive days following completion of standard-of-care antibiotics enabled VE303 strains to be inoculated when the intestinal environment was most permissive to colonization. VE303 use led to lower levels of pro-inflammatory and potentially pathogenic Gram-negative species, including Klebsiella and Citrobacter, that are linked to CDI recurrence and AMR bacterial infections. Taken together, these results demonstrate that VE303 works through multiple mechanisms to reduce CDI recurrence. Results from the CONSORTIUM study informed the design and dose selection for the global, pivotal Phase 3 study, RESTORATiVE303, that is currently underway to confirm the efficacy and safety profile of VE303 in the prevention of rCDI. Topline data for this study are expected in 2026. This project has been supported in whole or in part with federal funds from the Department of Health and Human Services; Administration for Strategic Preparedness and Response; Biomedical Advanced Research and Development Authority (BARDA), under contract number 75A50120C00177. About VE303 VE303 is a potential first-in-class Live Biotherapeutic Product for the prevention of recurrent Clostridioides difficile infection (rCDI). VE303 is an orally administered, defined bacterial consortium therapeutic candidate which consists of eight strains that were rationally selected using Vedanta's product engine. VE303 is produced from pure, clonal bacterial cell banks, which yield a standardized drug product in powdered form and bypass the need to rely on direct sourcing of donor fecal material of inconsistent composition. Vedanta published positive results in JAMA in April 2023 from the Phase 2 CONSORTIUM trial, in which VE303 met its primary endpoint of preventing C. difficile infection recurrence at eight weeks. Vedanta is currently enrolling patients into a Phase 3 RESTORATiVE303 registrational study of VE303 for the prevention of recurrent C. difficile infection. Vedanta Biosciences received a $5.4 million research grant from the Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) in 2017 and a contract of up to $81.9 million from Biomedical Advanced Research and Development Authority (BARDA) in 2020 to support clinical studies of VE303. VE303 was granted Orphan Drug Designation in 2017 by the U.S. Food and Drug Administration (FDA) for the prevention of recurrent CDI. About Vedanta Biosciences Vedanta Biosciences is a clinical-stage biopharmaceutical company developing medicines for the treatment of gastrointestinal diseases. The company's lead assets are potential first-in-class oral therapies – VE303, in a Phase 3 registrational trial for prevention of recurrent C. difficile infection, and VE202, in a Phase 2 trial for treatment of ulcerative colitis. Vedanta's pipeline has been built using the company's industry-leading product engine for the development of therapies based on defined consortia of bacteria grown from pure clonal cell banks. The product engine, supported by broad foundational intellectual property, includes one of the largest libraries of bacteria isolated from the human microbiome, vast clinical datasets, proprietary capabilities in consortium design, and end-to-end CGMP manufacturing capabilities at commercial launch scale.
