CHIASMA OPTIMAL trial, conducted under SPA and designed to support FDA approval, met the primary and all secondary endpoints

MYCAPSSA® NDA on track for submission by year-end 2019

MPOWERED^TM Phase 3 trial, designed to support EU approval, progressing as planned with topline data expected in 2H 2020

WALTHAM, Mass., Nov. 05, 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 reported financial results for the third quarter ended September 30, 2019 and provided a business update.  

In July, Chiasma reported topline results from its CHIASMA OPTIMAL global Phase 3 clinical trial designed to support marketing approval of its oral octreotide capsules product candidate, conditionally trade named MYCAPSSA®, in the United States. The trial, which was conducted under a Special Protocol Assessment (SPA) agreement with the FDA, met the primary and all secondary endpoints. If approved, MYCAPSSA will be the first oral somatostatin analog that we believe has the potential to change the standard of pharmacological care in the management of patients with acromegaly.  

Key CHIASMA OPTIMAL data highlights include:

Primary Endpoint:

• 58% of patients on octreotide capsules maintained biochemical control (IGF-1 ≤ 1.0 x ULN) at the end of study vs. 19% on placebo (p = 0.008). We believe this data is consistent with the efficacy physicians may expect for a potential maintenance treatment for acromegaly patients.
  

Secondary Endpoints:

• Of patients who were growth hormone (GH) responders at screening, 78% of patients on octreotide capsules maintained their GH response at the end of the core study versus 30% for placebo (p=0.001)
• Median time to loss of IGF-1 response (as defined by either >1.0 or ≥ 1.3 x ULN) was not reached (>36 Weeks) for patients on octreotide capsules vs. 16 weeks on placebo (p < 0.001)
• 25% of patients on octreotide capsules required rescue with SSA Injections vs. 68% on placebo (p = 0.003); stated otherwise, 75% of patients on octreotide capsules completed the trial (of which 90% elected to continue into the open label extension)

Exploratory Analysis:

• Mean IGF-1 values across all patients treated with octreotide capsules remained within normal limits (≤ 1.0 x ULN) up to the end of oral treatment
• 75% of patients on MYCAPSSA achieved an IGF-1 ≤ 1.1 x ULN at the end of treatment  

Octreotide capsules appeared safe and well tolerated in the study population, and no new or unexpected safety signals were observed.

Chiasma remains on track to file its NDA by year end and expects possible FDA approval in mid-2020, following an expected six-month PDUFA review classification. In parallel, the company is conducting a Phase 3 study, MPOWERED^TM, which is designed to support an application for marketing approval in the European Union, and the company remains on track to report topline data in the second half of 2020.

In September, Chiasma hosted a Key Opinion Leader meeting for investors featuring Susan L. Samson, MD, PhD, FRCPC, FACE, Associate Professor at Baylor College of Medicine in Houston, Texas, and Jill Sisco, President of Acromegaly Community, Inc., a patient organization that helps educate patients and their families regarding this rare disease. The presentation by Dr. Samson and Ms. Sisco, which is available under the events and presentations section of the company’s website, underscored the burdens that persist with the current standard-of-care, monthly SSA injections, including injection site pain and reactions. If marketing approval is granted by the FDA, MYCAPSSA would be the first approved oral somatostatin analog treatment in an injectables-only adult acromegaly maintenance treatment market. 

“In our CHIASMA OPTIMAL trial, 90% of the patients who completed the trial on MYCAPSSA elected to continue into the open label extension, which we believe reflects the strong preference by acromegaly patients for an oral treatment option. We also observed that 75% of patients on MYCAPSSA achieved an IGF-1 ≤ 1.1 x ULN at the end of treatment, which we believe will be clinically meaningful to physicians.  If approved, we believe MYCAPSSA would be well positioned to potentially become a new standard of pharmacological care for the management of acromegaly,” said Raj Kannan, Chief Executive Officer of Chiasma. “We made significant progress in the third quarter with our commercial preparedness and have hired key talent in marketing and market access and also accelerated our hiring in medical affairs” Mr. Kannan concluded.

Third Quarter 2019 Financial Results

• G&A Expenses: General and administrative expenses were $4.1 million for the third quarter ended September 30, 2019, compared with $2.3 million for the same period of 2018. The current period results include increased compensation related expenses, the initiation of pre-commercial activities, and increased insurance premiums which were primarily offset by a reduction in legal costs.
• R&D Expenses: Research and development expenses were $4.1 million for the third quarter ended September 30, 2019, compared with $5.5 million for the same period of 2018. The decrease was primarily driven by a decrease in clinical trial costs and was offset by increased manufacturing and regulatory costs.
• Net Loss: For the quarter ended September 30, 2019, net loss was ($7.7) million, or ($0.20) per basic share, compared with ($7.5) million, or ($0.31) per basic share, in the same period of 2018.
• Financial Position: In August, Chiasma completed a follow-on offering of common stock that raised net proceeds of approximately $52.3 million.  Chiasma ended the third quarter with cash, cash equivalents and marketable securities of $102.7 million.

CHIASMA OPTIMAL Trial Design
The CHIASMA OPTIMAL trial was a randomized, double-blind, placebo-controlled, nine-month clinical trial of octreotide capsules that was conducted under a special protocol assessment, or SPA, agreement with the FDA. The trial enrolled 56 adult acromegaly patients whose disease was biochemically controlled by injectable somatostatin analogs (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 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 and 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 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 Trial

Chiasma is also conducting an international Phase 3 clinical trial under a protocol accepted by the EMA for the Company’s octreotide capsules product candidate for the maintenance therapy of adult patients with acromegaly. The trial, referred to as MPOWERED, is a global, randomized, open-label and active-controlled, 15-month trial intended to support approval in the European Union. Chiasma completed enrollment of 146 adult acromegaly patients into the trial in June 2019, of which at least 80 patients who are responders to octreotide capsules per the protocol following a six-month run-in were randomized to either octreotide capsules or injectable somatostatin receptor ligands (octreotide LAR or lanreotide autogel), 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 second half of 2020.
