Chiasma is focused on improving the lives of patients who face challenges associated with existing treatments for their rare and debilitating diseases. The company's proprietary Transient Permeability Enhancer (TPE®) technology platform is designed to enable the intestinal absorption of molecules that would otherwise have limited intestinal bioavailability.

The company is developing octreotide capsules (conditionally trade named Mycapssa®) for the potential maintenance treatment of adults with acromegaly.

The company completed an international Phase 3 trial of octreotide capsules, 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.
