Clostridium Difficile Infections Overview

Clostridium difficile (C. difficile) is a Gram-positive, spore-forming, anaerobic bacillus widely distributed in the intestinal tract of humans and animals and in the environment. In the last decade, the frequency and severity of C. difficile infection have been increasing worldwide, making it one of the most common hospital-acquired infections. Transmission occurs by the fecal-oral route, and the most important risk factors include antibiotic therapy, old age, and hospital or nursing home stay. C. difficile colonizes the large intestine, and healthy adults with an adequate immune response can become asymptomatic carriers. Neonates also have a high asymptomatic carrier rate owing to a lack of intestinal receptors for the bacterium. Antibiotic use alters the microbial flora of the large intestine, rendering it susceptible to infection.

Diarrhea and colitis, the hallmark features of the infection, are caused by clostridial glycosylation exotoxins: toxin A (TcdA), an enterotoxin, and toxin B (TcdB), which is cytotoxic. A few pathological strains produce an additional binary toxin, the role of which is not elucidated. Once intracellular, both toxins inactivate pathways mediated by the Rho family of proteins, resulting in damage to colonocytes, disruption of intercellular tight junctions, and colitis. Toxin A directly activates neutrophils, while both toxins are involved in neutrophil chemotaxis.

Management involves a multi-step approach: discontinuing the inciting antibiotics, isolating the patient, and administering an antibiotic based on severity, usually vancomycin or fidaxomicin. Asymptomatic patients with a positive stool toxin test do not require treatment. Intravenous metronidazole can be used in patients with ileus, where oral delivery would be delayed, whereas vancomycin cannot be given intravenously because it is not secreted into the colon. Surgical intervention, such as subtotal colectomy with rectal preservation, may be required in fulminant colitis with complications such as toxic megacolon, intestinal perforation, and necrotizing colitis.

First recurrence can be treated with a prolonged taper and pulsed vancomycin regimen or with fidaxomicin if vancomycin was used for the initial episode. Second or further recurrences can be treated with a taper and pulsed vancomycin regimen, vancomycin followed by rifaximin, fidaxomicin, or fecal transplantation. Bezlotoxumab, a human monoclonal antibody against C. difficile toxin, has been approved for managing recurrent infections, with a clinical study showing positive outcomes. Fecal transplantation, in which stool from a healthy donor is introduced into the intestinal tract of a person with disrupted microbial balance, has reported an 80% to 90% success rate in reducing recurrence.

Clostridium Difficile Infections Emerging Drugs Profile

  • VE303: Vedanta Biosciences

VE303 is a potential first-in-class live biotherapeutic product candidate being developed by Vedanta Biosciences to prevent recurrence of Clostridioides difficile infection (CDI). It consists of a rationally designed, defined bacterial consortium of 8 strains of clonal human commensal bacteria selected for their ability to provide colonization resistance to C. difficile. VE303 is administered orally in capsules and produced under cGMP conditions from pure, clonal bacterial cell banks, yielding a standardized drug product. In a Phase II study, high-dose VE303 met its primary endpoint of preventing CDI recurrence at eight weeks in patients at high risk of recurrence, and it was generally well tolerated. Vedanta is currently enrolling patients into a pivotal Phase III registrational study called RESTORATiVE303 to evaluate the efficacy and safety of VE303 for the prevention of recurrent CDI.

  • Ibezapolstat: Acurx Pharmaceuticals

Ibezapolstat (formerly ACX-362E) is Acurx’s lead antibiotic candidate and the first in a new class of Pol IIIC inhibitors in clinical development to treat C. difficile infections. In June 2018, the U.S. FDA designated ibezapolstat a Qualified Infectious Disease Product (QIDP) for the treatment of patients with CDI, making it eligible for incentives under the Generating New Antibiotic Incentives Now (GAIN) Act. In January 2019, the FDA granted it Fast Track designation. The CDC has designated C. difficile an urgent threat, highlighting the need for new antibiotics. The drug is currently in the Phase II stage of development for Clostridium Difficile Infections.
