Officials with the FDA issued Zealand Pharma a response letter saying that the application did not meet the full requirements for substantial evidence to establish the efficacy and safety of the to-be-marketed dose of glepaglutide for the treatment of short bowel syndrome in adults with intestinal failure.1
The double-blind, phase 3 EASE-1 (NCT03690206) trial demonstrated that 24 weeks of treatment with 10 mg glepaglutide led to a drop in total weekly volume of parenteral support from baseline by 3.13 liters, but that reduction was not statistically significant with once-weekly doses and 5.13 liters (P=.0039) with twice-weekly doses compared with 2.85 liters with placebo.
Patients who received placebo in EASE-1 were rerandomized to treatment with either glepaglutide 10 mg once or twice weekly. Patients who complete EASE-2 are eligible to participate in EASE-3 (NCT04881825), evaluating glepaglutide administered once weekly using an auto-injector. EASE-4 (NCT04991311) is a phase 3b trial to assess long-term effects of glepaglutide on intestinal fluid and energy uptake.
Zealand Pharma expects to initiate a single phase 3 trial in 2025 that is anticipated to support marketing authorizations for glepaglutide in geographies outside the United States and European Union and provide further confirmatory evidence for a regulatory resubmission in the United States, according to a statement from the company.
