Abstract
Clostridioides difficile infection (CDI) poses a persistent challenge in healthcare, with substantial morbidity and mortality implications. This comprehensive review explores current CDI management, emphasising guidelines from IDSA, SHEA, and ESCMID. Additionally, this study spotlights recent drug developments that have the potential to reshape CDI treatment paradigms. Within the current treatment landscape, fidaxomicin, vancomycin, bezlotoxumab, and faecal microbiota transplantation offer varied options, each with its unique strengths and limitations. Fidaxomicin, effective yet resource-constrained, presents a dilemma, with vancomycin emerging as a pragmatic alternative. Bezlotoxumab, though augmenting antibiotics, grapples with cost and safety concerns. Meanwhile, faecal microbiota transplantation, highly efficacious, confronts evolving safety considerations. The horizon of CDI treatment also features promising therapies such as SER-109 and Rebyota, epitomising the evolving paradigm. As CDI management advances, the critical role of standardised microbiome restoration therapies becomes evident, ensuring long-term safety and diversifying treatment strategies.

Abstract
INTRODUCTION Clostridioides difficile infection (CDI) causes symptoms of varying severity and negatively impacts patients' health-related quality of life (HRQL). Despite antibiotic treatment, recurrence of CDI (rCDI) is common and imposes clinical and economic burdens on patients. Fecal microbiota, live-jslm (REBYOTA [RBL]) is newly approved in the USA for prevention of rCDI following antibiotic treatments. We analyzed efficacy and HRQL impact of RBL vs. placebo in patients at first rCDI using data from the phase 3 randomized, double-blind placebo-controlled clinical trial, PUNCH CD3. METHODS This post hoc analysis included patients at first rCDI fromPUNCH CD3. Treatment success (i.e., absence of diarrhea within 8 weeks post-treatment) was analyzed adjusting for baseline patient characteristics. HRQL was measured using the Clostridioides difficile Quality of Life Survey (Cdiff32); absolute scores and change from baseline in total and domain (physical, mental, and social) scores were summarized and compared between arms. Analyses were conducted for the trial's blinded phase only. RESULTS Among 86 eligible patients (32.8% of the overall trial population, RBL 53 [61.6%], placebo 33 [38.4%]), RBL-treated patients had significantly lower odds of recurrence (i.e., greater probability of treatment success) at week 8 vs. placebo (odds ratio 0.35 [95% confidence interval 0.13, 0.98]). Probability of treatment success at week 8 was 81% for RBL and 60% for placebo, representing 21% absolute and 35% relative increases for RBL (crude proportions 79.2% vs. 60.6%; relative risk 0.53, p = 0.06). Additionally, RBL was associated with significantly higher Cdiff32 total (change score difference 13.5 [standard deviation 5.7], p < 0.05) and mental domain (16.2 [6.0], p < 0.01) scores vs. placebo from baseline to week 8. CONCLUSION Compared to placebo, RBL demonstrated a significantly higher treatment success in preventing further rCDI and enhanced HRQL among patients at first recurrence, establishing RBL as an effective treatment to prevent further recurrences in these patients. TRIAL REGISTRATION ClinicalTrials.gov Identifier NCT03244644.

Abstract
Background Microbiota-based treatments reduce the incidence of recurrent Clostridioides difficile infections (rCDIs), but prospectively collected safety data needed to broaden patient access and protect public health have been limited. Objectives We provide cumulative safety data from five prospective clinical trials evaluating fecal microbiota, live-jslm (RBL) - the first microbiota-based live biotherapeutic product approved by the US Food and Drug Administration - for preventing rCDI in adults. Design Integrated safety analysis includes three phase II trials (PUNCH CD, PUNCH CD2, PUNCH Open-Label) and two phase III trials (PUNCH CD3, PUNCH CD3-OLS) of RBL. Methods Trial participants were at least 18 years of age with documented rCDI who completed standard-of-care antibiotic therapy before treatment with RBL. Assigned study treatment regimen was one or two doses of RBL (or placebo) administered rectally, depending on the trial design. In four of the five trials, participants with CDI recurrence within 8 weeks after RBL or placebo administration were eligible for treatment with open-label RBL. Treatment-emergent adverse events (TEAEs) were recorded for at least 6 months following last study treatment; in PUNCH CD2 and PUNCH Open-Label trials, TEAEs and serious TEAEs were collected through 12 and 24 months, respectively. Results Among the five trials, 978 participants received at least one dose of RBL (assigned treatment or after recurrence) and 83 participants received placebo only. TEAEs were reported in 60.2% of Placebo Only participants and 66.4% of RBL Only participants. Only abdominal pain, nausea, and flatulence were significantly higher in the RBL Only group compared with the Placebo Only group. Most TEAEs were mild or moderate in severity and were most frequently related to preexisting conditions. There were no reported infections for which the causative pathogen was traced to RBL. Potentially life-threatening TEAEs were infrequent (3.0% of participants). Conclusion Across five clinical trials, RBL was well tolerated in adults with rCDI. In aggregate, these data consistently demonstrated the safety of RBL.

Abstract
Although research on the role of the gut microbiota (GM) in human health has sharply increased in recent years, what a "healthy" gut microbiota is and how it responds to major stressors is still difficult to establish. In particular, anticancer chemotherapy is known to have a drastic impact on the microbiota structure, potentially hampering its recovery with serious long-term consequences for patients' health. However, the distinguishing features of gut microbiota recovery and non-recovery processes are not yet known. In this narrative review, we first investigated how gut microbiota layouts are affected by anticancer chemotherapy and identified potential gut microbial recovery signatures. Then, we discussed microbiome-based intervention strategies aimed at promoting resilience, i.e., the rapid and complete recovery of a healthy gut microbial network associated with a better prognosis after such high-impact pharmacological treatments.

Abstract
Clostridioides difficile infections (CDIs) remain a healthcare problem due to high rates of relapsing/recurrent CDIs (rCDIs). Breakdown of colonization resistance promoted by broad-spectrum antibiotics and the persistence of spores contribute to rCDI. Here, we demonstrate antimicrobial activity of the natural product class of chlorotonils against C. difficile. In contrast to vancomycin, chlorotonil A (ChA) efficiently inhibits disease and prevents rCDI in mice. Notably, ChA affects the murine and porcine microbiota to a lesser extent than vancomycin, largely preserving microbiota composition and minimally impacting the intestinal metabolome. Correspondingly, ChA treatment does not break colonization resistance against C. difficile and is linked to faster recovery of the microbiota after CDI. Additionally, ChA accumulates in the spore and inhibits outgrowth of C. difficile spores, thus potentially contributing to lower rates of rCDI. We conclude that chlorotonils have unique antimicrobial properties targeting critical steps in the infection cycle of C. difficile.

Biomedicines 2023; 11:biomedicines11020426. [PMID: 36830964 PMCID: PMC9953237 DOI: 10.3390/biomedicines11020426] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 01/25/2023] [Accepted: 01/26/2023] [Indexed: 02/05/2023] Open
Abstract
Clostridioides difficile infection (CDI) is an urgent threat and unmet medical need. The current treatments for CDI are not enough to fight the burden of CDI and recurrent CDI (r-CDI). This review aims to highlight the future drugs for CDI and their related patented applications. The non-patent literature was collected from PubMed and various authentic websites of pharmaceutical industries. The patent literature was collected from free patent databases. Many possible drugs of the future for CDI, with diverse mechanisms of action, are in development in the form of microbiota-modulating agents (e.g., ADS024, CP101, RBX2660, RBX7455, SYN-004, SER-109, VE303, DAV132, MET-2, and BB128), small molecules (e.g., ridinilazole, ibezapolstat, CRS3123, DNV3837, MGB-BP-3, alanyl-L-glutamine, and TNP-2198), antibodies (e.g., IM-01 and LMN-201), and non-toxic strains of CD (e.g., NTCD-M3). The development of some therapeutic agents (e.g., DS-2969b, OPS-2071, cadazolid, misoprostol, ramoplanin, KB109, LFF571, and Ramizol) stopped due to failed clinical trials or unknown reasons. The patent literature reveals some important inventions for the existing treatments of CDI and supports the possibility of developing more and better CDI-treatment-based inventions, including patient-compliant dosage forms, targeted drug delivery, drug combinations of anti-CDI drugs possessing diverse mechanisms of action, probiotic and enzymatic supplements, and vaccines. The current pipeline of anti-CDI medications appears promising. However, it will be fascinating to see how many of the cited are successful in gaining approval from drug regulators such as the US FDA and becoming medicines for CDI and r-CDI.

Orenstein R. The Role of Microbiome-Based Therapeutics in Clostridioides difficile Infection: Durable, Long-Term Results of RBX2660. Infect Dis Ther 2023; 12:1-7. [PMID: 36342653 PMCID: PMC9868035 DOI: 10.1007/s40121-022-00714-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 10/05/2022] [Indexed: 11/09/2022] Open
Abstract
A recently published manuscript described findings from a phase 2 open label study of the microbiota-based live biotherapeutic product RBX2660 in patients with two or more previous recurrent Clostridioides difficile infection (rCDI) episodes, and described long-term safety and sustained treatment success through 24 months. As previous studies have typically focused on short-term clinical outcomes, these new data provide insight into the tolerability, safety, and efficacy of RBX2660 over the long term. When microbiota-based products were first evaluated, the long-term efficacy and safety were principal concerns of the United States Food and Drug Administration. Microbiota-based live biotherapeutic products (LBPs) represent an emerging approach to the management of CDI and perhaps other gastrointestinal and medical conditions whose pathogenesis is defined by microbial dysbiosis. RBX2660 is a human-derived, broad consortium microbiota-based LBP that consists of a population of microbes obtained from healthy stool donors and may reflect the symbiotic nature of a healthy colonic microbiome. RBX2660 is rectally administered and does not require sedation or special preparation of the recipient. Potential advantages of the rectal administration of RBX2660 include the ease of administration and lack of need for any bowel preparation, which may benefit those who are frail, have swallowing issues, or cannot take bowel laxative preparations. In this multicenter prospective trial of rCDI, patients who achieved treatment success 8 weeks after receiving RBX2660 continued to have a sustained clinical response over the course of long-term follow-up, with more than 90% of treatment responders remaining CDI-free at 6, 12, and 24 months. Following receipt of RBX2660, the gut microbiota of those with treatment success were restored from a dysbiotic state to become more diverse and similar to RBX2660 composition. The restoration of the microbiota occurred as early as 7 days after RBX2660 administration and remained stable through the 24-month analysis. No new adverse outcomes were observed during the prospective assessment, and the safety profile of RBX2660 was consistent with previous studies. Based on the clinical studies, RBX2660 will most likely benefit those with ≥ 1 rCDI episode or those who are at a high risk of subsequent rCDI, such as patients who have comorbid conditions including renal disease, heart disease, or inflammatory bowel disease, or who are immunosuppressed.
