A Pilot Study on the Efficacy and Safety of a Novel Synbiotic Formula (SGR11) in Patients With Inflammatory Bowel Disease (IBD)

Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, is characterized by chronic relapsing inflammation of the gastrointestinal tract driven by dysregulated immune responses to intestinal microbiota. Extensive evidence demonstrates that IBD is associated with marked gut microbiota dysbiosis, including loss of key short-chain fatty acid (SCFA)-producing taxa and enrichment of pro-inflammatory or mucosa-associated organisms. These microbial alterations contribute to impaired epithelial barrier integrity, shifts in microbial metabolite profiles, activation of mucosal immune pathways, and increased susceptibility to persistent intestinal inflammation. Additionally, IBS-like symptoms remain common among individuals with IBD, even during clinical remission, indicating ongoing functional and microbiota-related disturbances not fully addressed by conventional therapies. Synbiotics, which combine probiotic and prebiotic components in a synergistic formulation, represent a promising therapeutic strategy targeting microbial and mucosal mechanisms relevant to IBD. Components within SGR11 have demonstrated potential in preclinical and clinical research to modulate intestinal inflammation, enhance epithelial barrier function, influence T-cell-mediated immune responses, improve microbial fermentation profiles, and support restoration of gut microbiota homeostasis. Prebiotic elements within synbiotic formulations may further promote beneficial microbial activity, reinforce mucosal structural integrity, and modulate host immune responses. This pilot, single-arm clinical trial will evaluate the safety and preliminary efficacy of SGR11 over an 8-week intervention period in adults with IBD. The study will assess global clinical improvement, symptom indices, patient-reported outcomes, biochemical markers of intestinal inflammation and permeability, and gut microbiome composition and functional characteristics using stool-based assays
