MRM Health announces positive Phase 2a results in Ulcerative Colitis
VIB spin-off MRM Health today announced promising results from its Phase 2a clinical trial in mild-to-moderate Ulcerative Colitis.

VIB spin-off MRM Health, a clinical-stage biopharmaceutical company focused on developing next-generation live microbiome consortia therapeutics, today reports positive topline results from its Phase 2a clinical trial with MH002 in mild-to-moderate Ulcerative Colitis (UC).
MRM Health’s MH002-UC-201 study was a multi-center, double-blind, randomized, placebo-controlled trial in 45 UC patients at multiple clinical sites in Belgium, Poland and Czech Republic. The study was designed to evaluate safety (primary endpoint), initial efficacy and mechanistic effects of MH002 over eight weeks, with a further eight-week extension period. More information about the trial is available at clinicaltrialsregister.eu.
The primary endpoint was met with an excellent safety profile and tolerance at a fixed dose of 400mg per day over 16 weeks administration. Treatment-Emergent Adverse Events (TEAE) were reported in 35% of patients allocated to MH002 treatment compared to 57% when treated with placebo and there was no evidence of adverse reactions related to MH002.
Initial efficacy on disease activity was evidenced in clinically relevant parameters, including a 12% improvement in Mayo Endoscopic Severity (MES) score (p=0.05, 1-sided Wilcoxon rank sum test), while placebo worsened by 5%. Stool consistency significantly improved in the MH002 treatment group as from week 2 (p=0.006; 1-sided Student t-test). At the end of the eight-week period, 18% of subjects achieved clinical remission compared to 0% of the placebo group (Per-protocol analysis). As opposed to previous trials with other live biotherapeutics in UC, this study was performed successfully without vancomycin preconditioning.
At a mechanistic level, anti-inflammatory effect was demonstrated with 42% decrease in median fecal calprotectin (a clinically relevant bowel inflammation marker) compared to 18% in placebo at week 8.
“These early results indicate that MH002 is safe and well tolerated by patients, and has potential efficacy in mild-to-moderate UC patients who have not responded sufficiently to first-line treatment,” commented Séverine Vermeire, coordinating investigator of study MH002-UC-201 and Professor of Medicine at the KU Leuven, Belgium. “There is a significant absence of treatments for UC patients, particularly in this population, so I look forward to conducting the full analysis of the data and following MH002’s progression through the clinic.”
Bruce Sands, Professor of Medicine at the Icahn School of Medicine at Mount Sinai, New York and paid consultant to MRM Health, added: “MH002’s mechanism of action and anti-inflammatory effect in UC look very promising, with the potential of a highly favorable benefit/risk balance, pending larger confirmatory studies. These topline results also suggest that this formulation could have applications across a wider range of other inflammatory bowel disorders, including pouchitis, in which MH002 is also being tested.”
Full analysis and presentation of the data is expected by the end of 2023. The Company has initiated to progress the program into Phase 2/3 development.
Ludo Haazen, Chief Medical Officer at MRM Health, added: “This early clinical study enables us to move forward with our clinical programme in UC. We are excited to see that MH002 differentiated in this early study significantly and consistently from placebo in clinically relevant parameters, including the centrally assessed MES, which was supported by the mechanistic parameters we have measured.”
MH002 is currently the most advanced rationally-designed consortium therapy in the UC field. It was developed through MRM Health’s proprietary CORAL® Technology and comprises six well-characterized commensal strains, selected and optimized to tackle key disease-driving mechanisms with enhanced potency, resiliency, and engraftment. Production is via MRM Health’s breakthrough scalable and standardized cGMP manufacturing platform, allowing the manufacturing of complete consortia as a single drug substance. The ability of CORAL® to enable scalable, cost-effective manufacturing of complete optimized consortia in a single process is expected to provide both key regulatory and patient compliance advantages.
In addition to the recently completed UC trial, MH002 is being tested in an ongoing multi-center, open label Phase 2 study enrolling patients with acute Pouchitis, a rare disease with high unmet medical need.
Sam Possemiers, Chief Executive Officer at MRM Health, said: “These early clinical data are very important for the Company, since they further validate our proprietary CORAL® technology which underlies our portfolio of live biotherapeutic products. The data enables us to take the next steps in our business strategy where we will be engaging with regulatory agencies in all territories and potential new partners as well as driving forward the rest of our development portfolio.”
