Recurrent Clostridium Difficile Infection Clinical Trial
A Randomised, Controlled, Open-label Phase III Clinical Trial in Patients With Primary or Recurrent Clostridioides Difficile (CD) Infection, to Evaluate the Efficacy and Safety of Capsules of Lyophilised Faecal Microbiota vs Fidaxomicin.
Patients with microbiota alterations developed after being exposed to antibiotics are especially susceptible to Clostridioides difficile infections (CDI). The incidence and severity of CDI has increased in recent years and CDI recurrences (r-CDI) due to the appearance of new episodes in patients with a previous cured CDI, represent a serious and complex clinical issue. Although antibiotics are the recommended therapy for the first episode of CDI, treatment with oral vancomycin and/or metronidazole often results in significant treatment failure. In addition, the treatment of r-CDI is not adequately standardized, and although the most widely used treatment is the administration of fidaxomicin and bezlotoxumab, its efficacy in patients who already have r-CDI is not proven. In the late years, Fecal Microbiota Transfer (FMT) has emerged as the preferred non-pharmacological treatment to manage CDI with multiple recurrences and recent clinical trials have evaluated its potential efficacy and safety in the treatment of patients with primary CD infection. The objective of this study is to assess the efficacy and safety of the MBK-01 medication, consisting of heterologous lyophilized fecal microbiota capsules coming from healthy donors in comparison to the treatment with Fidaxomicin, in 66 patients with primary or r-CDI.
This is a Phase III, multicenter, controlled and open label clinical trial in which patients who suffered an episode of Clostridioides difficile infection (either the first episode or subsequent recurrences) will be randomly assigned (1:1) to one of the following arms: - Dificlir (Fidaxomicina) - MBK-01 (heterologous lyophilized fecal microbiota) Objective: To assess the efficacy of FMT with capsules of lyophilized fecal microbiota (MBK-01), compared to the control (fidaxomicin) at 8 weeks after the start of the treatment. To assess the safety of MBK-01 and the quality of life of patients participating in the study. Follow up: participants will return for clinic visits at 72 hours, week 3 and week 8 after the start of the treatment, and will receive follow-up phone calls at month 3 and month 6 after the start of the treatment. Stool samples will be collected from participants for further studies at time 0 and week 8 after the start of the treatment. Study Outcomes are detailed in the specific section of this website. Rationale: The transferred microbiota restores the recipient's intestinal microbiota by reintroducing bacterial taxa that were absent or in low proportion in the recipient before the FMT, supporting the expansion of the recipient's own commensal microbiota and re-establishing a microbiota community with a high biodiversity. Donors: All donors are screened to ensure they meet the strict requirements necessary to maintain the safety of the MBK-01. Justification: The treatment of Clostridioides difficile infections (CDI) with antibiotics is usually effective for acute symptoms, but after the initial treatment, the probability of recurrence at 8 weeks ranges from 10-20 % of cases, and once a patient has a recurrence, the probability of further recurrences increases up to 40-65 %. In recent years, Fecal Microbiota Transfer (FMT) has emerged as the preferred non-pharmacological treatment to manage CDI with multiple recurrences and recent clinical trials have evaluated its potential efficacy and safety in the treatment of patients with primary CD infection. Although antibiotics are the recommended therapy for the first episode of CDI, treatment with oral vancomycin and/or metronidazole often results in significant treatment failure, with recurrences occurring in up to 30-40% of patients. Furthermore, antibiotic treatment does not correct deficiencies in the intestinal microbiota that facilitate CD infection and is associated with the risk of the emergence of antibiotic-resistant bacteria. Moreover, the treatment of recurrences is not adequately standardized. In recent years, although the most widely used alternatives have been fidaxomicin and bezlotoxumab, their efficacy in patients who already suffer from r-CDI is not proven. The administration of the FMT through oral capsules, although it is not standardized, has proven to be effective in the restoration of intestinal microbiota of patients with r-CDI. In addition, the use of lyophilized formulas facilitates the concentration of bacteria and further optimizes the donors' sample and reduces the amount of capsules that the patient has to ingest. ;
