About the CHIASMA OPTIMAL Trial
The CHIASMA OPTIMAL trial was a randomized, double-blind, placebo-controlled, nine-month Phase 3 clinical trial of octreotide capsules that was conducted under a special protocol assessment (SPA) agreement with the FDA. The trial was designed to evaluate the proportion of patients who maintain their biochemical response to MYCAPSSA® (oral octreotide capsules) compared to placebo. The trial enrolled 56 adult acromegaly patients whose disease was biochemically controlled by injectable somatostatin analogs (octreotide or lanreotide) based upon levels of IGF-1, a byproduct of increased growth hormone (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. 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 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 reversion to prior treatment. As previously announced, CHIASMA OPTIMAL met the primary endpoint and all secondary endpoints.
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 randomized to a nine-month controlled phase with continued treatment on MYCAPSSA or on their prior injectable therapy. Patients were randomized to either MYCAPSSA (n=55) or injectable somatostatin receptor ligands (octreotide long-acting release or lanreotide autogel) (n=37), and then followed for an additional nine months. The primary endpoint of the trial was time-weighted average of IGF-1 <1.3 x upper limit of normal (ULN) during the nine-month randomized, controlled treatment (RCT) phase. As previously announced, MPOWERED met its primary endpoint of non-inferiority compared to long acting SSA injectables.

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. Chiasma estimates that approximately 8,000 adult acromegaly patients are chronically treated with somatostatin analog injections in the United States.
