About

The primary objectives of this study are to assess the safety and efficacy of MS1819 in enteric capsules vs porcine pancreatic enzyme replacement therapy (PERT) in patients with exocrine pancreatic insufficiency (EPI) due to cystic fibrosis (CF). The exploratory objective of the extension phase (EP) is to find a dose of MS1819 in immediate release capsules that is safe and results in CFA values in a therapeutic range.

Full description

This is a Phase 2, open-label, multicenter, 2, 2x2 crossover study assessing the safety and efficacy of MS1819, 2240 mg/day vs porcine PERT, and 4480 mg/day vs porcine PERT given at the same dose and dosing regimen that was being administered during the pre-study period. MS1819 will be administered in enteric capsules.

MS1819 will be assessed in a 2x2 crossover including approximately 30 patients completing both periods. Fifteen patients will be randomized to the MS1819 2240 mg/day vs PERT arm, and 15 patients will be randomized to the MS1819 4480 mg/day vs PERT arm. Patients in each arm will further be randomized to receive either the sequence consisting of MS1819 for 3 weeks followed by PERT for another 3 weeks or the opposite sequence of treatments, PERT for 3 weeks followed by MS1819 for another 3 weeks.The coefficient of fat absorption (CFA) will be measured at the end of each 3 week study period. Patients enrolled into the extension phase (EP) will be composed of patients who have completed the crossover phase of OPTION 2.
