Pilot Study to Evaluate Advantages and Disadvantages of TOXCLEAN As Add on Treatment to SOC in Patients with Clostridium Difficile-associated Diarrhea
This is a single center, randomized, exploratory clinical investigation that will evaluate the safety and efficacy of Toxclean (ABResearch srl) as add on treatment to Standard therapy in 24 patients with recurrent CDAD. Eligible subjects will be adult patients with recurrent CDAD. Recurrent CDAD, for the purpose of this protocol, is defined as one or more new episode of diarrhea (Ned) within two months from the end of the SoC treatment. The objective of this pilot study is to evaluate whether 1 or 2 grams of Toxclean powder is orally administrable and well tolerated as add on treatment to SoC in patients with recurrent CDAD.

• Diagnosis of recurrent CDAD, defined as those episodes of C. Difficile associated diarrhea occurring 2-8 weeks after either the symptoms resolution of a previous CDAD episode or C. difficile negativization of fecal sample.
• Detection of C. difficile toxins by nucleic acid amplification tests (NAAT), EIA or GDH;
• Received at least one course of adequate antibiotic therapy for CDAD (≥ 10 days of vancomycin at a dose of ≥125 mg four times per day, ≥ 10 days of metronidazole at a dose of 500mg three times per day or fidaxomixin 200mg twice a day for 10 days)
