1.Exploring ways to improve CDI outcomes.
Galpérine T;Guery B;French Group of Fecal Microbiota Transplantation (GFTF) Med Mal Infect. 2018 Feb;48(1):10-17. doi: 10.1016/j.medmal.2017.10.009. Epub 2018 Jan 12.

Clostridium difficile is an anaerobic spore-forming Gram-positive bacillus recognized as an evolving international health problem. Metronidazole and vancomycin were - until recently - the only drugs available to treat C. difficile infection (CDI). Better knowledge of the pathophysiology and the development of new drugs completely modified the management of initial episodes and recurrences of CDI. Fidaxomicin significantly reduced recurrences compared with vancomycin. New drugs are also currently evaluated (cadazolid, surotomycin, ridinilazole, rifaximin). Gut microbiota homeostasis was clearly shown to be a key determinant in recurrences as demonstrated by the development of gut microbiota transplantation and alternative microbiota substitution. Passive immunotherapy and vaccinal approaches are also currently being evaluated. In conclusion, CDI treatment has evolved with the development of new therapeutic pathways which now need to be implemented in international guidelines.

2.Antimicrobial susceptibility and ribotypes of Clostridium difficile isolates from a Phase 2 clinical trial of ridinilazole (SMT19969) and vancomycin.
Snydman DR;McDermott LA;Thorpe CM;Chang J;Wick J;Walk ST;Vickers RJ J Antimicrob Chemother. 2018 Aug 1;73(8):2078-2084. doi: 10.1093/jac/dky135.

Objectives: ;We evaluated the antimicrobial susceptibility and ribotypes of Clostridium difficile isolates from participants in a Phase 2 study of ridinilazole, a novel targeted-spectrum agent for treatment of C. difficile infection.;Methods: ;Participants received ridinilazole (200 mg twice daily) or vancomycin (125 mg four times daily) for 10 days (ClinicalTrials.gov: ;NCT02092935;). The MICs of ridinilazole and comparators for C. difficile isolates from stool samples were determined by agar dilution. Toxin gene profiling was performed by multiplex PCR and ribotype identification by capillary electrophoresis.;Results: ;Eighty-nine isolates were recovered from 88/100 participants (one participant had two strains at baseline). The median colony count (cfu/g stool) was 1.9?×?104 (range: 2.5?×?102-7.0?×?106). Twelve participants (three received ridinilazole and nine received vancomycin) experienced recurrence, confirmed by immunoassays for free toxin in stool samples. The ribotype of eight out of nine isolates obtained at recurrence matched those of the initial isolates. All isolates, including those obtained at recurrence, were susceptible to ridinilazole within the expected range [median (range) MIC: 0.

3.New and emerging therapies for Clostridium difficile infection.
Martin J;Wilcox M Curr Opin Infect Dis. 2016 Dec;29(6):546-554.

PURPOSE OF REVIEW: ;Clostridium difficile infection has attained high prominence given its prevalence and impacts on patients and healthcare institutions. Multiple new approaches to the prevention and treatment of C. difficile infection (CDI) are undergoing clinical trials.;RECENT FINDINGS: ;Bezlotoxumab is a monoclonal antibody against toxin B that has successfully completed phase III studies, demonstrating a significant reduction in recurrent CDI when given with standard of care antibiotics. Antibiotics under development include cadazolid and ridinilazole, whereas surotomycin has had disappointing phase III results. Multiple live biotherapeutics are being developed, including freeze thawed and encapsulated versions of faecal microbiota transplantation to improve the practicality of treating patients with recurrent CDI. Alternatives to faecal microbiota transplantation, that aim to improve safety, including a microbial suspension, RBX2660, and a complex spore formulation, SER-109, have progressed to phase II studies. A nontoxigenic C. difficile strain has also shown promise to prevent recurrent CDI. In addition, three C. difficile vaccines have progressed to phase II/III clinical trials.
