Ascending Doses of Crofelemer Powder for Oral Solution in Pediatric Microvillus Inclusion Disease (MVID)
brief summary
A study that will evaluate the safety, tolerability and preliminary efficacy of multiple ascending doses of crofelemer, compared to placebo, using a randomized cross-over design within each dose level, when administered to participants with MVID receiving parenteral support (PS, defined as TPN with or without supplementary IV fluid requirements). Blinded study drug will be administered as a novel crofelemer formulation, Crofelemer Powder for Oral Solution, or a matching placebo powder formulation for oral solution. Assigned study drug will be reconstituted and administered orally (or enterally) three times daily (TID) as a concentrated liquid formulation in each of the three dose levels.
detailed description
The study consists of an initial randomized double-blind placebo-controlled study, followed by an up to 48-week partially blinded extension phase.
The double-blind study phase is a randomized, double-blind, placebo-controlled, dose-escalating study with a placebo crossover design within each dose level in this ultra-rare MVID participant population. For the primary objective, safety and tolerability, comparisons between the crofelemer and placebo, across treatment periods within each dose level and through the end of the double-blind treatment period will be descriptively summarized. For secondary objectives, changes from the Baseline Period will be assessed.
After completion of the study and the No Treatment Period, if the Investigator and the DMC consider it appropriate for the participant's best interest based on safety and tolerability, the participant will be eligible to enter a Partially Blinded Extension Phase. Following approval by the DMC, the participant will enter the extension phase for up to 48 additional weeks of treatment with crofelemer at the dose selected by the DMC. The Investigator and the Sponsor will remain blinded to the selected dose.
