FDA sets PDUFA date of June 26, 2020

Acceptance follows December 26, 2019 NDA resubmission

NEEDHAM, Mass., Jan. 13, 2020 (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 announced that the U.S. Food and Drug Administration (FDA) accepted for review the New Drug Application (NDA) resubmission for its oral octreotide capsules investigational product candidate, conditionally trade named MYCAPSSA®. Chiasma is developing MYCAPSSA for the maintenance treatment of adults with acromegaly. The FDA assigned a Prescription Drug User-Fee Act (PDUFA) target action date of June 26, 2020, which is a six-month review.

“The FDA acceptance of our NDA resubmission marks the achievement of the first planned 2020 milestone for Chiasma and is a significant step towards making MYCAPSSA available to eligible patients,” said Raj Kannan, Chief Executive Officer of Chiasma. “If approved, we believe MYCAPSSA, as the first oral somatostatin analog, has the potential to change the standard of pharmacological care in the management of patients with acromegaly. We look forward to working with the FDA during the review process towards a potential approval.”

About Acromegaly

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. We believe that approximately 8,000 adult acromegaly patients are chronically treated with somatostatin analogs in the United States.

About Chiasma

Chiasma is focused on improving 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.

Prior to trial initiation, the company reached agreement with the FDA on the design of the trial through a special protocol assessment. In January 2020, the FDA accepted the company’s NDA resubmission seeking marketing approval of MYCAPSSA in the U.S. The PDUFA target action date is June 26, 2020.  Chiasma is headquartered in Needham, MA with a wholly-owned subsidiary in Israel.
