Published: August 2013

The novel antibiotic MBX-500, dosed at 100, 200, or 400 mg/kg twice daily for 7 days, was evaluated for the treatment of Clostridium difficile infection (CDI) in the gnotobiotic pig model. MBX-500 increased survival at all doses and at high doses improved clinical signs and reduced lesion severity, similar to vancomycin. Our results show that MBX-500 is an effective antibiotic for the treatment of diarrhea associated with CDI and prevents severe systemic disease.

Beneficial effect of oral tigecycline treatment on Clostridium difficile infection in gnotobiotic piglets.

Antimicrob Agents Chemother

December 2014

Department of Infectious Disease and Global Health, Tufts University, North Grafton, Massachusetts, USA

The efficacy of oral tigecycline treatment (2 mg/kg of body weight for 7 days) of Clostridium difficile infection (CDI) was evaluated in the gnotobiotic pig model, and its effect on human gut microflora transplanted into the gnotobiotic pig was determined. Tigecycline oral treatment improved survival, clinical signs, and lesion severity and markedly decreased concentrations of Firmicutes but did not promote CDI. Our data showed that oral tigecycline treatment has a potential beneficial effect on the treatment of CDI.

Clostridium difficile infection (CDI) causes moderate to severe disease, resulting in diarrhea and pseudomembranous colitis. CDI is difficult to treat due to production of inflammation-inducing toxins, resistance development, and high probability of recurrence. Only two antibiotics are approved for the treatment of CDI, and the pipeline for therapeutic agents contains few new drugs.
