FDA Accepts Re-filed NDA for Acromegaly Drug
FDA has accepted for review a Chiasma NDA resubmission for Mycapssa (octreotide) capsules for the maintenance treatment of adults with acromegaly. According to Chiasma, acromegaly typically develops when a benign tumor of the pituitary gland produces too much growth hormone, which leads to significant health problems and early death if untreated. There are about 69,000 individuals with acromegaly worldwide. The agency set a 6/26 user fee review action target date.
In 2016, FDA sent Chiasma a complete response letter on the original submission. It said the submission had not provided substantial evidence of efficacy to warrant approval and that another clinical trial was needed in order to overcome this deficiency. It also expressed concerns regarding certain aspects of the company’s single-arm, open-label Phase 3 clinical trial and strongly recommended that the company conduct a randomized, double-blind and controlled trial that enrolled patients from the U.S. “and be of sufficiently long duration to ensure that control of disease activity is stable at the time point selected for the primary efficacy assessment,” the company said at the time.
The company says the resubmission includes data from the company’s recent CHIASMA OPTIMAL Phase 3 clinical trial. Prior to beginning that trial, Chiasma says it reached agreement with FDA on its design through a special protocol assessment.
