Chiasma Provides Update on Ongoing Mycapssa® Phase 3 Clinical Trials


On track with U.S. Phase 3 CHIASMA OPTIMAL trial; data now expected by mid-Q3 2019

Target enrollment completed in ongoing Phase 3 MPOWERED™ trial; data expected in 2H 2020

WALTHAM, Mass., June 27, 2019 (GLOBE NEWSWIRE) -- Chiasma, Inc. (NASDAQ: CHMA), a clinical-stage biopharmaceutical company focused on improving the lives of patients with rare and serious chronic diseases, today provided an update on the clinical development of its octreotide capsules product candidate, conditionally trade-named Mycapssa®, which is currently being evaluated in two ongoing, international Phase 3 clinical trials for the maintenance treatment of adults with acromegaly, the CHIASMA OPTIMAL and MPOWERED™ trials. 

  • In the Phase 3 CHIASMA OPTIMAL trial, which is being conducted under a special protocol assessment agreement, or SPA, with FDA, the company announced that the last enrolled patient completed the trial earlier this month. The company now expects to release top-line data by mid-Q3.  Importantly, all 56 patients enrolled in the trial reached the final 36-week visit with no patient dropouts from the trial reported through the 36-week double-blind and controlled phase of the trial.
     
  • In the MPOWERED™ Phase 3 clinical trial, which is designed to support approval in the European Union, the company also announced that it has also completed enrollment.  In October 2018, after 80 patients were randomized into the nine-month controlled phase of the trial (from the 135 patients enrolled in the run-in phase), the company elected to resume enrollment in an effort to enroll additional patients exclusively located in the United States in order to gain further U.S. investigator and patient experience with octreotide capsules.  Of the 146 total patients that have entered the six-month run-in phase, 84 patients (or greater than 60%) have completed the run-in phase of the trial and were randomized into the nine-month randomized controlled phase, while 10 patients currently remain active in the run-in phase.

“We are rapidly approaching a potentially transformational milestone for our company, with the anticipated release of CHIASMA OPTIMAL top-line data that, if positive, will support an NDA filing later this year,” said Raj Kannan, Chief Executive Officer. “As we prepare for commercialization, we are encouraged by the positive feedback we have received from patients, physicians, and scientific experts on the value of an oral treatment alternative to the current standard of care, somatostatin analog injections. We look forward to potential U.S. approval of Mycapssa in mid-2020 as we advance toward our long-term goal of transforming the treatment paradigm for patients with acromegaly in the U.S. and around the world.”

“Our two Phase 3 clinical trials of Mycapssa® are progressing as planned, and we look forward to reporting top-line data from CHIASMA OPTIMAL by mid-third quarter and MPOWERED™ in the second half of next year,” said Gary Patou, MD, Head of Clinical.

William Ludlam, MD, PhD, Senior Vice President of Clinical Development and Medical Affairs, added, “There is a substantial body of evidence to suggest that current acromegaly treatments are burdensome for some patients and there remains a significant unmet medical need. We are grateful to the investigators and trial patients who helped to efficiently advance our clinical program to this point, and we look forward to the timely completion of these important trials.”
