Safety and Durability of RBX2660 (Microbiota Suspension) for Recurrent Clostridium difficile Infection: Results of the PUNCH CD Study

BACKGROUND Managing recurrent Clostridium difficile infection (CDI) presents a significant challenge for clinicians and patients. Fecal microbiota transplantation (FMT) is a highly effective therapy for recurrent CDI, yet availability of a standardized, safe, and effective product has been lacking. Our aim in this study was to assess the safety and effectiveness of RBX2660 (microbiota suspension), a commercially prepared FMT drug manufactured using standardized processes and available in a ready-to-use format. METHODS Patients with at least 2 recurrent CDI episodes or at least 2 severe episodes resulting in hospitalization were enrolled in a prospective, multicenter open-label study of RBX2660 administered via enema. Intensive surveillance for adverse events (AEs) was conducted daily for 7 days following treatment and then at 30 days, 60 days, 3 months, and 6 months. The primary objective was product-related AEs. A secondary objective was CDI-associated diarrhea resolution at 8 weeks. RESULTS Of the 40 patients enrolled at 11 centers in the United States between 15 August 2013 and 16 December 2013, 34 received at least 1 dose of RBX2660 and 31 completed 6-month follow-up. Overall efficacy was 87.1% (16 with 1 dose and 11 with 2 doses). Of 188 reported AEs, diarrhea, flatulence, abdominal pain/cramping, and constipation were most common. The frequency and severity of AEs decreased over time. Twenty serious AEs were reported in 7 patients; none were related to RBX2660 or its administration. CONCLUSIONS Among patients with recurrent or severe CDI, administration of RBX2660 via enema appears to be safe and effective. CLINICAL TRIALS REGISTRATION NCT01925417.

Ertapenem - a potent treatment for clinical and quality of life improvement in patients with hidradenitis suppurativa

A paucity of knowledge exists regarding the use of ertapenem in hidradenitis suppurativa. Our retrospective chart review and telephone interview aims to investigate the utility of intravenous ertapenem in severe, refractory hidradenitis suppurativa.

Brincidofovir as Salvage Therapy for Adenovirus Disease in Intestinal Transplant Recipients.

Adenoviruses are double‐stranded DNA viruses that typically cause mild self‐limiting respiratory, ocular, and gastrointestinal infections. In immunocompromised patients, especially transplant recipients, the infection can be severe, with dissemination and multiorgan failure. In intestinal transplant recipients, the incidence is as high as 57%. To our knowledge, no standardized guidelines or U.S. Food and Drug Administration–approved medications exist for the treatment of adenovirus disease.
