Significant and Durable Microbiome Restoration in a Phase 3 Trial of Fecal Microbiota, Live-JSLM for Recurrent Clostridioides difficile Infection When Administered by Colonoscopy (ACG 2025) - P3 | "Overall, 41 received RBL via colonoscopy; 39 participants completed an 8-week visit, with a treatment success rate of 95%.There were 20 participants with a full stool sample timeline (baseline, 1 week, 4 weeks, 8 weeks, 3 months, and 6 months) and 18 with a baseline sample and at least 1 post-administration sample. Compared with baseline, microbiome composition and MHI-A shifted significantly towards RBL composition among responders. Bacteroidia and Clostridia increased in abundance, whereas Gammaproteobacteria and Bacilli decreased following RBL administration via colonoscopy (Figure 1)."

Comparison of the Efficacy and Safety of Live Fecal Microbiota Therapeutics for Recurrent Clostridioides difficile Infection (CDI): Matching-Adjusted Indirect Treatment Comparison in Patients With ≥1 CDI Recurrence (ACG 2025) - "The orally administered fecal microbiota spores, live-brpk (VOS) and rectally administered fecal microbiota, live-jslm (RBL), with different compositions, are both FDA-approved for any patients with rCDI. Of the 33 publications identified in the SLR, six, reporting on two distinct studies including patients with ≥1 recurrent episode were deemed eligible for the MAIC. VOS was significantly more efficacious than RBL in preventing rCDI at 8 weeks (odds ratio [OR]; 9.23 [95% confidence interval (CI): 4.24, 20.08]). The time to recurrence over time was significantly lower with VOS compared with RBL (hazard ratio; 0.19 [95% CI; 0.10, 0.33])."

Long-Term Safety of Fecal Microbiota, Live-jslm Administered via Colonoscopy to Adults With Recurrent Clostridioides difficile Infection: 6-Month Safety Data From CDI-SCOPE, a Single-Arm, Phase 3b Trial (ACG 2025) - P3 | "Of the 41 participants, 39 completed follow-up through 6 months. From 8 weeks through 6 months after RBL administration, 36 additional TEAEs in 15 participants (36.6%) were reported, 1 of which (irritable bowel syndrome) was RBL-related. During this period, most TEAEs (97.2%) were of mild or moderate severity, and 1 serious, potentially life-threatening TEAE (worsening abdominal pain) unrelated to RBL was observed."

Efficacy of Fecal Microbiota Transplant for Prevention of Recurrent CDI in Patients Diagnosed With Cancer (ACG 2025) - "Vancomycin and fidaxomicin were the most frequently used antibiotics, and 18.8% received bezlotoxumab.Colonoscopy-delivered FMT was the most common intervention (68.1%), followed by Rebyota (17.4%) and VOWST (7.2%); combination strategies were used in 7.2%. A total of 69 patients with a history of CDI or rCDI were included. Hematologic malignancies were the most common cancer type (29.6%), and nearly half had stage III–IV disease. At the time of their most recent CDI episode, 55% were receiving active cancer therapy."

Evaluation of Fecal Microbiota, Live-jslm by Standard of Care Antibiotic Washout Period for the Prevention of Recurrent Clostridioides difficile Infection (ACG 2025) - "Of the 130 patients who received RBL, 99 patients were in Group 1 and 31 patients were in Group 2 (Table 1). The median days of washout period were 2 days in Group 1 and 9 days in Group 2 (p< 0.0001). The two groups had a similar median age (Group 1: 72; Group 2: 71), same median Charlson Comorbidity Index of 4.0, with female being the majority in both."

What's New and What's Next in Fecal Microbiota Transplantation? (PubMed, Biologics) - "In recent years, the FDA approved two standardized microbiota-based therapeutics-Rebyota™ (fecal microbiota, live-jslm) and Vowst™ (fecal microbiota spores, live-brpk)-for rCDI prevention. Meanwhile, regulatory pathways and clinical guidelines for microbiota-derived biologics and live biotherapeutic products continue to evolve. In this manuscript, we provide an update on the emerging use of FDA-approved prescription microbiota-derived therapeutics for the prevention of rCDI, review data on investigational agents including both donor dependent and donor independent microbial products, and summarize current evidence on the use of conventional FMT for indications beyond prevention of rCDI."

Clinician Management Preferences for Clostridioides difficile Infection in Adults: A 2024 Emerging Infections Network Survey. (PubMed, Open Forum Infect Dis) - "Additionally, 72% (357/498) reported that their institutional guidelines recommended vancomycin as the first-line agent. The most common barrier to fidaxomicin use was challenges with outpatient insurance coverage (82% [408/496]). Bezlotoxumab was available to 74% (370/500) of respondents, though 33% (165/497) indicated they do not use bezlotoxumab routinely...Fecal microbiota live-jslm was available to 36% (179/500), and fecal microbiota spores live-brpk was available to 30% (150/500). Significant barriers, including high costs, insurance challenges, and limited availability of CDI therapies, impact clinical decision-making and adherence to guideline recommendations."

Emerging therapies such as VE303 (Vedanta) are being studied to refine treatment approaches and expand the use of microbiota-based therapies. Further studies are needed to standardize guidelines, improve patient outcomes, and better define the role of FMT in the treatment of diseases beyond recurrent CDI."

CLINICAL OUTCOMES IN PATIENTS WITH RECURRENT CLOSTRIDIOIDES DIFFICILE INFECTION AFTER MICROBIOTA RESTORATION THERAPY WITH FECAL MICROBIOTA SPORES, LIVE-BRPK (VOWST/VOS) (DDW 2025) - "Background: The management of recurrent Clostridioides difficile infection (rCDI) has significantly evolved since the FDA approval of two live biotherapeutic treatments for prevention of rCDI, including VOWST /VOS and Rebyota...VOS is an oral capsule that may be administered to adult patients after the first or second recurrence of CDI, following antibiotic treatment with either vancomycin or fidaxomicin... VOS was effective in prevention of rCDI with no adverse events reported in long-term follow-up. The efficacy in our cohort was lower than reported in clinical trials, but most of these patients received antibiotics for an indication other than CDI. In patients who receive VOS and must receive an antibiotic following the course of VOS, secondary prophylaxis with oral vancomycin could be considered to reduce the risk of recurrence."
