Chiasma completed an international Phase 3 trial of octreotide capsules (conditionally trade named Mycapssa®), the results of which have been published in the Journal of Clinical Endocrinology and Metabolism. 

Chiasma is conducting a Phase 3 clinical trial under a Special Protocol Assessment agreement reached with the U.S. Food and Drug Administration for its octreotide capsules product candidate for the maintenance therapy of adult patients with acromegaly. The trial, referred to as “CHIASMA OPTIMAL” (Octreotide capsules vs. Placebo Treatment In MultinationAL centers), is a global, randomized, double-blind, placebo-controlled, nine-month trial. It is expected to enroll 50 adult acromegaly patients. The trial is designed to evaluate the proportion of patients who maintain their biochemical response to octreotide capsules compared to placebo. The company plans to initiate enrollment in CHIASMA OPTIMAL in the second half of 2017 and anticipates the release of top-line data from this Phase 3 clinical trial by the end of 2019.

Chiasma also is conducting an international Phase 3 clinical trial under a protocol accepted by the European Medicines Agency (EMA) for the company’s octreotide capsules product candidate for the maintenance therapy of adult patients with acromegaly. The trial, referred to as MPOWERED™ (Maintenance of Acromegaly Patients with Octreotide Capsules Compared with Injections – Evaluation of Response Durability), is a global, randomized, open-label and active-controlled, 15-month trial. It is expected to enroll up to 150 adult acromegaly patients. The trial was initiated in March 2016 and is designed to evaluate the proportion of patients who maintain their biochemical response to octreotide capsules and patient-reported outcomes in patients treated with octreotide capsules, compared to patients treated with standard of care injectable somatostatin receptor ligands (octreotide or lanreotide). The company anticipates the release of top-line data from this Phase 3 clinical trial in 2020.
