Trial design

Randomised, open-label, randomized comparison of two-dosing regimens of frozen encapsulated fecal microbiota transfer (fmt) products with or without an individualized donor selection approach; study arms include antibiotic induction regimen in combination with high-dose individualized oral encapsulated fmt versus alternative dosing/selection strategy. (no specific drug doses or schedules specified in the available data.)-controlled Phase II trial across 6 sites in Germany.
