Chiasma Announces Positive Topline Results from the MPOWERED™ Phase 3 Clinical Trial Comparing MYCAPSSA® (octreotide capsules) to Long Acting Injectables for the Maintenance Treatment of Adults with Acromegaly
91% of patients on MYCAPSSA maintained IGF-1 response in the 9-month randomized, controlled phase of the non-inferiority trial
Company intends to submit a marketing application for MYCAPSSA in the EU in mid-2021

NEEDHAM, Mass., Nov. 18, 2020 (GLOBE NEWSWIRE) -- Chiasma, Inc. (NASDAQ: CHMA), a commercial-stage biopharmaceutical company utilizing its delivery platform technology to develop and commercialize oral therapies to improve the lives of patients with rare diseases on burdensome and painful injections, today announced positive top-line data from its global Phase 3 MPOWERED™ non-inferiority clinical trial comparing MYCAPSSA® (oral octreotide capsules) to long-acting injectable somatostatin analogs (SSAs) for maintenance of biochemical response in patients with acromegaly. The MPOWERED trial was designed to support a planned marketing authorization application for MYCAPSSA in the European Union. MYCAPSSA is currently approved in the United States for long-term maintenance treatment in acromegaly patients who have responded to and tolerated treatment with injectable octreotide or lanreotide.
The MPOWERED non-inferiority trial was designed to compare long-term maintenance treatment with MYCAPSSA, the first and only approved oral SSA therapy for acromegaly, to the long-acting injectables octreotide long-acting release and lanreotide autogel, in patients previously responding to these therapies. After a six-month run-in phase, 92 patients who were responders to MYCAPSSA were randomized to a nine-month controlled phase with continued treatment on MYCAPSSA or on their prior injectable therapy.
“We are excited with the positive results from the MPOWERED study that demonstrated non-inferiority relative to long-acting SSAs. These results further strengthen the available robust clinical data set for MYCAPSSA and provide additional meaningful information for healthcare providers in treating patients with acromegaly,” said Raj Kannan, chief executive officer of Chiasma. “In light of these positive results, we plan to submit a marketing authorization application for MYCAPSSA to the European Medicines Agency in mid-2021. While we are excited to report the preliminary top line results, further analyses of the trial results are ongoing, and we plan to present the full data set from the study at upcoming medical conferences in 2021.”
“I am pleased that the MPOWERED study met its primary endpoint of non-inferiority compared to long acting SSA injectables. These results should provide treating physicians with confidence that patients on injectables who are switched to oral octreotide can be expected to achieve comparable efficacy and safety,” commented Maria Fleseriu, MD, FACE, lead investigator of the MPOWERED study, Professor of Medicine and Neurological Surgery, Director of the Pituitary Center at Oregon Health and Science University in Portland, Oregon, Immediate Past President of the Pituitary Society. “Many patients with acromegaly experience significant burdens with SSA injections, including injection site pain and reactions, and I believe that the results of the MPOWERED study underscore the importance of an oral treatment alternative for patients with acromegaly.”
MPOWERED™ MYCAPSSA® Safety:
The safety profile of MYCAPSSA capsules in the MPOWERED trial was consistent with the known safety profile of octreotide but without adverse injection site reactions. No new or unexpected safety signals were detected during the study among MYCAPSSA subjects. ee Important Safety Information below for contraindications, warnings, precautions and adverse reactions associated with MYCAPSSA based in the current approved labeling in the United States.

MPOWERED™ Phase 3 Trial Design
The MPOWERED trial was a global, randomized, open-label and active-controlled, 15-month trial intended to support approval of MYCPASSA in the European Union. Chiasma completed enrollment of 146 adult acromegaly patients into the trial in June 2019, of which 92 patients who were deemed responders to octreotide capsules per the protocol following a six-month run-in were randomized to either octreotide capsules (n=55) or injectable somatostatin receptor ligands (octreotide long-acting release or lanreotide autogel) (n=37), and then followed for an additional nine months. The trial was 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 leading injectable somatostatin analogs.
