First Industry Sponsored U.S. Disease State Registry for Acromegaly Began Enrolling PatientsNEEDHAM, Mass., March 16, 2020 (GLOBE NEWSWIRE) — Chiasma, Inc. (NASDAQ: CHMA), a clinical stage biopharmaceutical company focused on improving the lives of patients who face challenges associated with their existing treatments for rare and serious chronic diseases, today reported financial results for the fourth quarter and year ended December 31, 2019 and provided a business update.“Our focus for 2020 is on obtaining U.S. regulatory approval for MYCAPSSA^® as a maintenance treatment for adult patients with acromegaly and subsequently executing a successful launch,” said Raj Kannan, Chief Executive Officer of Chiasma. “With our NDA resubmission accepted for review by the FDA, we are preparing for a commercial launch to establish the foundation needed for long-term growth.”Recent Business Highlights and Anticipated 2020 MilestonesMYCAPSSA NDA Acceptance: Chiasma announced on January 13, 2020 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, for the 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 Management of Acromegaly (MACRO) Registry: Chiasma began enrolling patients in the first-ever industry sponsored U.S. disease state registry for acromegaly. The MACRO registry is designed to enroll patients from over 40 clinical sites in the U.S. and collect real-world data on treatment burden and effectiveness of various acromegaly treatments.
 Publication of CHIASMA OPTIMAL Phase 3 Clinical Trial Results: Chiasma plans to submit the positive results of the CHIASMA OPTIMAL trial to a peer-reviewed journal for expected publication in mid-2020.
 MYCAPSSA Planned U.S. Commercial Launch: Chiasma plans to launch MYCAPSSA in the United States in the fourth quarter of 2020, pending the FDA’s timely approval of the NDA and either of the planned prior approval manufacturing supplements to the NDA.
 Top-line MPOWERED Phase 3 Clinical Trial Results: Chiasma expects to report top-line results from the MPOWERED (Maintenance of acromegaly Patients with Octreotide capsules compared With injections – Evaluation of REsponse Durability) Phase 3 open-label clinical trial of octreotide capsules in the fourth quarter of 2020.
 Pipeline Expansion Leveraging Transient Permeability Enhancer (TPE^®) Technology: Chiasma plans to announce its pipeline expansion plans to develop one or more oral therapies targeting diseases with unmet needs following the anticipated approval of MYCAPSSA for the maintenance treatment of adults with acromegaly.Fourth Quarter and Year Full Year 2019 Financial Results and OutlookG&A Expenses: General and administrative expenses were $5.9 million for the fourth quarter ended December 31, 2019, compared with $2.7 million for the same period of 2018. The current period results include increased pre-commercial activity and compensation related expenses which were primarily offset by a reduction in legal expenses. General and administrative expenses were $15.1 million for the year ended December 31, 2019, compared with $10.0 million for the year ended December 31, 2018. The increase was primarily driven by the initiation of pre-commercial activities and compensation related expenses which were primarily offset by a reduction in legal expenses.
 R&D Expenses: Research and development expenses were $6.4 million for the fourth quarter ended December 31, 2019, compared with $5.7 million for the same period of 2018. The increase was primarily driven by increased regulatory and manufacturing costs and offset by decreased clinical trials costs. Research and development expenses were $22.5 million for the year ended December 31, 2019, compared with $22.4 million for the year ended December 31, 2018. Though the change was immaterial, we observed an increase in regulatory and manufacturing costs offset by a decrease in clinical trials costs.
 Net Loss: For the quarter ended December 31, 2019, net loss was ($12.0) million, or ($0.29) per basic share, compared with ($8.1) million, or ($0.32) per basic share, for the same period of 2018. For the year ended December 31, 2019, net loss was ($36.3) million, or ($1.06) per basic share, compared with ($31.3) million, or ($1.28) per basic share, for the same period of 2018.
 Cash Position and Outlook: Cash, cash equivalents and marketable securities as of December 31, 2019, were $92.4 million, compared with $41.7 million as of December 31, 2018. The Company expects that its current cash, cash equivalents and marketable securities balance is sufficient to fund its operations as currently planned through at least 2020.Conference Call and Webcast InformationChiasma management will host a conference call and webcast to discuss the fourth quarter results in more detail today, March 16, 2020, at 5:00 pm ET.

The trial enrolled 56 adult acromegaly patients whose disease was biochemically controlled by injectable somatostatin analogs based upon levels of IGF-1, a byproduct of increased growth hormone, or GH, levels caused by acromegaly (average IGF-1 ≤ 1.0 × upper limit of normal (ULN)). The patients also had confirmed active acromegaly following their last surgical intervention based upon an elevated IGF-1 at that time of ≥ 1.3 × ULN. Patients were randomized on a 1:1 basis, to octreotide capsules or placebo. Patients were dose titrated from 40 mg per day (equaling one capsule in the morning and one capsule in the evening) to up to a maximum of 80 mg per day (equaling two capsules in the morning and two capsules in the evening). Patients who met the predefined withdrawal criteria, or discontinued from oral treatment for any reason, in either treatment arm during the course of the trial were considered treatment failures, reverted to their original treatment of injections and monitored for the remainder of the trial. The primary endpoint of the trial was the proportion of patients who maintained their biochemical response at the end of the nine-month, double-blind, placebo-controlled period as measured using the average of the last two IGF-1 levels ≤ 1.0 × ULN (assessed at weeks 34 and 36). Hierarchical secondary endpoints that are expected to be considered by the FDA in evaluating the totality of evidence for octreotide capsules treatment effect include: proportion of patients who maintain GH response at week 36 compared to screening; time to loss of response: IGF-1 of 2 consecutive visits is > 1.0 × ULN; time to loss of response: IGF-1 of 2 consecutive visits is ≥ 1.3 × ULN; and proportion of patients requiring rescue treatment.MPOWERED™ Phase 3 TrialChiasma is also conducting an international Phase 3 clinical trial under a protocol accepted by the EMA for the company’s oral octreotide capsules for the maintenance treatment of adult patients with acromegaly. The trial, referred to as MPOWERED, is a randomized, open-label and active-controlled, 15-month trial intended to support regulatory approval in the European Union. Chiasma completed enrollment of 146 adult acromegaly patients into the trial in June 2019. In January 2020, the randomization of patients was completed. Of the 146 patients that entered the six-month run-in phase of the trial, 92 of these patients (or 63%) completed the run-in phase and were deemed to be responders to octreotide capsules per protocol (IGF-1 <1.3 x ULN and GH<2.5 ng/mL). Responders to octreotide capsules were randomized (2:3) per protocol to either go back to their original long-acting injectable somatostatin analog or remain on octreotide capsules at the dose identified during the run-in phase and then followed for an additional nine months.   The trial 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. Chiasma expects to release top-line data from the MPOWERED Phase 3 clinical trial during the fourth quarter of 2020.About AcromegalyAcromegaly 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 ChiasmaChiasma 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. In July 2019, the company reported positive topline data from its CHIASMA OPTIMAL Phase 3 clinical trial for its octreotide capsules product candidate, conditionally trade named MYCAPSSA, for the maintenance therapy of adult patients with acromegaly in whom prior treatment with somatostatin analogs has been shown to be effective and tolerated. 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.
