Submission supported by previously announced data from Phase 3 MPOWERED™ study
NEEDHAM, Mass., June 28, 2021 (GLOBE NEWSWIRE) -- Chiasma, Inc. (NASDAQ: CHMA), (“Chiasma” or the “Company”), 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 currently treated with burdensome and painful injections, today announced that it has submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) seeking approval of MYCAPSSA® (oral octreotide capsules) as a maintenance therapy for adults with acromegaly.
The MAA is supported by positive results from Chiasma’s global Phase 3 MPOWERED™ non-inferiority clinical trial comparing MYCAPSSA to long-acting injectable somatostatin analogs (iSSAs) for maintenance of biochemical response in patients with acromegaly who previously responded to both therapies. MYCAPSSA, the first and only oral somatostatin analog for the treatment of acromegaly approved by the Food and Drug Administration (FDA), is available in the U.S. for long-term maintenance treatment in acromegaly patients who have responded to and tolerated treatment with injectable octreotide or lanreotide.
"We are pleased to submit our marketing authorization application to the EMA as planned, as this marks an important step forward in our mission to expand the availability of MYCAPSSA to patients outside the U.S. suffering from acromegaly,” said Raj Kannan, chief executive officer of Chiasma.
About the CHIASMA MPOWERED™ Trial
The MPOWERED™ trial was a global, randomized, open-label and active-controlled, 15-month trial intended to support approval of MYCAPSSA® (oral octreotide capsules) in the European Union. This non-inferiority clinical trial was designed to compare MYCAPSSA to long-acting injectable somatostatin analogs (SSAs) for maintenance of biochemical response in patients with acromegaly. The trial enrolled 146 adult acromegaly patients of which 92 patients who were responders to MYCAPSSA after a six-month run-in phase were then randomized to a nine-month controlled (RCT) phase to either receive continued treatment on MYCAPSSA (n=55) or their prior injectable therapy (octreotide long-acting release or lanreotide autogel) (n=37). The primary endpoint of the trial was time-weighted average of IGF-1 <1.3 x upper limit of normal during the nine-month RCT phase. As previously announced, MPOWERED met its primary endpoint of non-inferiority compared to long-acting SSA injectables.
INDICATION AND IMPORTANT SAFETY INFORMATION
INDICATION AND USAGE
MYCAPSSA (octreotide) delayed-release capsules, for oral use, is a somatostatin analog indicated for long-term maintenance treatment in acromegaly patients who have responded to and tolerated treatment with octreotide or lanreotide.
Hypersensitivity to octreotide or any of the components of MYCAPSSA. Anaphylactoid reactions, including anaphylactic shock, have been reported in patients receiving octreotide.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
MYCAPSSA can cause problems with the gallbladder. Monitor patients periodically. Discontinue if complications of cholelithiasis are suspected.
Blood sugar, thyroid levels, and vitamin B12 levels should be monitored and treated accordingly.
Bradycardia, arrhythmia, or conduction abnormalities may occur. Treatment with drugs that have bradycardia effects may need to be adjusted.
The most common adverse reactions (incidence >10%) are nausea, diarrhea, headache, arthralgia, asthenia, hyperhidrosis, peripheral swelling, blood glucose increased, vomiting, abdominal discomfort, dyspepsia, sinusitis, and osteoarthritis.
The following drugs require monitoring and possible dose adjustment when used with MYCAPSSA: cyclosporine, insulin, antidiabetic drugs, calcium channel blockers, beta blockers, lisinopril, digoxin, bromocriptine, and drugs mainly metabolized by CYP3A4. Counsel women to use an alternative non-hormonal method of contraception or a back-up method when MYCAPSSA is used with combined oral contraceptives.
Patients taking proton pump inhibitors, H2-receptor antagonists, or antacids concomitantly with MYCAPSSA may require increased dosages of MYCAPSSA.
Advise premenopausal females of the potential for an unintended pregnancy.

Acromegaly typically develops when a benign tumor of the pituitary gland produces too much growth hormone, ultimately leading to significant health problems. Common features of acromegaly are facial changes, intense headaches, joint pain, impaired vision and enlargement of the hands, feet, tongue and internal organs. Serious health conditions associated with the progression of acromegaly include type 2 diabetes, hypertension, respiratory disorders and cardiac and cerebrovascular disease. Chiasma estimates that approximately 8,000 adult acromegaly patients are chronically treated with somatostatin analog injections in the United States.
Chiasma is a commercial stage biopharmaceutical company focused on developing and commercializing oral therapies to improve the lives of patients who face challenges associated with their existing treatments for rare and serious chronic diseases. Employing its Transient Permeability Enhancer (TPE®) technology platform, Chiasma seeks to develop oral medications that are currently available only as injections. In June 2020, Chiasma received FDA approval of MYCAPSSA for long-term maintenance therapy in acromegaly patients who have responded to and tolerated treatment with octreotide or lanreotide. MYCAPSSA, the first and only oral somatostatin analog approved by the FDA, is available for commercial sale in the United States. Chiasma is headquartered in Needham, MA with a wholly owned subsidiary in Israel. MYCAPSSA, TPE and CHIASMA are registered trademarks of Chiasma.
