Fidaxomicin is an antibiotic that belongs to the class of the macrocyclics and is indicated for the treatment of CDI. In clinical trials, fidaxomicin, when compared to vancomycin, was non-inferior for the clinical cure of patients with CDI and superior for the reduction of recurrence rates, with a greater sustained response after 30 days. Of the patients included in the clinical trials, additional subgroup analyses were performed in patient subgroups with a higher risk of recurrence than the overall CDI population.
