Chiasma Reports Second Quarter 2019 Results

Announces positive data from Phase 3 CHIASMA OPTIMAL trial; MYCAPSSA^® NDA submission expected by year-end 2019 with an expected six-month PDUFA review time period

MPOWERED enrollment complete; topline data expected in second half 2020

Completes common stock offering for net proceeds of $51.5 million

WALTHAM, Mass., Aug. 08, 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 second quarter ended June 30, 2019 and provided a business update.

In July, Chiasma announced positive topline data from CHIASMA OPTIMAL, its international Phase 3 clinical trial of MYCAPSSA^® for the maintenance treatment of adults with acromegaly. The trial, which was conducted under a Special Protocol Assessment (SPA) agreement with the FDA, met the primary and all secondary endpoints. The primary endpoint was the percentage of patients on octreotide capsules compared to placebo who maintained their IGF-1 response through the 36-week core trial period (58% of the patients on octreotide capsules compared to 19% of the patients on placebo, with a p-value of 0.008). In addition, the trial met all four of its secondary endpoints. Chiasma expects to submit an NDA by the end of the year, with an expected six-month PDUFA review time period.

“We are pleased with the CHIASMA OPTIMAL trial results as they are consistent with expectations from physicians based on treatment response rates demonstrated in prior acromegaly clinical trial results of somatostatin analogs.  There is a significant momentum and a sense of urgency within the organization to get this novel innovative agent into the hands of patients that we expect could benefit from it,” noted Raj Kannan, Chief Executive Officer of Chiasma. “In the CHIASMA OPTIMAL trial, 75% of the patients randomized to the octreotide capsules treatment arm completed the 36-week trial on study drug, and 90% of those patients voluntarily elected to continue into the open label extension. We believe this speaks to the strong preference by patients for an oral option and the potential for Mycapssa, if approved, to be a positive disruptive agent in the market.”

During the second quarter, Chiasma announced that it had completed enrollment of 146 patients in its Phase 3 trial of MYCAPSSA^®, known as MPOWERED™, which is designed to support approval in the European Union. The trial is progressing as planned, and the company anticipates releasing topline data in the second half of 2020.

Also, in July, Chiasma completed a follow-on public offering of 10,000,000 shares of its common stock that raised net proceeds of approximately $51.5 million, after deducting underwriting discounts, commissions and estimated offering expenses.

Second Quarter 2019 Financial Results

• G&A Expenses: General and administrative expenses were $2.6 million for the second quarter ended June 30, 2019, compared with $2.6 million for the same period of 2018. The current period results include increased professional services fees which were primarily offset by a reduction in legal costs.
  
  
• R&D Expenses: Research and development expenses were $5.5 million for the second quarter ended June 30, 2019, compared with $6.3 million for the same period of 2018. The decrease in clinical trial costs was partially offset by an increase in manufacturing costs.
  
  
• Net Loss: For the quarter ended June 30, 2019, net loss was ($7.8) million, or ($0.25) per basic share, compared with ($8.7) million, or ($0.36) per basic share, in the same period of 2018.
  
  
• Cash Position: Chiasma ended the second quarter with cash, cash equivalents and marketable securities of $58.1 million. In July, the Company completed a follow-on offering of common stock that raised net proceeds of approximately $51.5 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.
