The Lancet Diabetes & Endocrinology Publishes Positive Results for the MPOWERED Phase 3 Trial for Mycapssa(R) (oral octreotide) in Acromegaly Patients

DUBLIN, Ireland, and Boston MA, January 4, 2022, Amryt (Nasdaq: AMYT, AIM: AMYT), a global, commercial-stage biopharmaceutical company dedicated to acquiring, developing and commercializing novel treatments for rare diseases, today announces that The Lancet Diabetes & Endocrinology has published the full results of the global Phase 3 MPOWERED clinical trial that compared Mycapssa(R) (oral octreotide capsules) to long-acting injectable Somatostatin Receptor Ligands (iSRLs) for maintenance of biochemical response in patients with acromegaly. The MPOWERED trial was designed to support the marketing authorization application for Mycapssa(R) to the EMA which is currently under evaluation. The MPOWERED trial adds to the evidence base built with two previous Phase 3 trials, CH-ACM-01 and CHIASMA OPTIMAL, both of which supported the US FDA approval of Mycapssa(R) for long-term maintenance treatment in acromegaly patients who have responded to and tolerated treatment with injectable octreotide or lanreotide.

Dr. Mark Sumeray, Chief Medical Officer of Amryt, commented: "Many patients with acromegaly experience breakthrough symptoms and significant burdens with SSA injections, including injection site pain and reactions. The publication of the MPOWERED Phase 3 results in The Lancet family of journals underscores their significance and potential clinical value of Mycapssa(R) for appropriate acromegaly patients."

Key outcomes of the MPOWERED Phase 3 Trial are listed below:

Mycapssa(R) was non-inferior to long-acting injectable octreotide or lanreotide in maintenance of biochemical control, in patients previously responding to both treatments

   -- On the primary endpoint of the proportion of patients maintaining 
      biochemical response throughout the 9-month Randomized Control Treatment 
      (RCT) phase, 91% of patients on Mycapssa(R) maintained response compared 
      to 100% on iSRLs. Response was defined as the time-weighted average of 
      IGF-1 <1.3 x upper limit of normal (ULN) throughout the phase. 
 
   -- Mean IGF-1 was the same at the start and end of the RCT phase in both 
      groups and was maintained within normal limits 
 
   -- All sensitivity analyses supported the results of the primary endpoint 
      using both time-weighted average and more traditional landmark methods of 
      analyzing IGF-1 data 

Oral octreotide results for breakthrough and active acromegaly symptoms

   -- At the end of the RCT phase, 15% of patients in the oral octreotide group 
      reported breakthrough symptoms of acromegaly, compared with 31% in the 
      iSRL group. The overall number of individual active acromegaly symptoms 
      was similar between treatment groups. 
 
   -- A significant reduction in the number of certain active acromegaly 
      symptoms was reported in patients responding to Mycapssa(R) at the end of 
      the run-in phase. Specifically, significant reductions were shown in the 
      proportions of participants with swelling of extremities (p=0.01) and 
      fatigue (p=0.03). 

Patient reported outcomes with oral octreotide capsules

   -- A significant improvement was reported from baseline while treated with 
      iSRLs to the end of the run-in phase in patients responding to 
      Mycapssa(R) in three of the five Acromegaly Treatment Satisfaction 
      Questionnaire (Acro-TSQ) scales (emotional reaction, treatment 
      convenience, and treatment satisfaction), with improving trends in the 
      other two scales (gastrointestinal interference and symptom interference) 
 
   -- Change from start of the RCT phase for each of the five Acro-TSQ scales 
      was generally similar between treatment groups 

Oral octreotide capsules showed comparable safety profile to iSRLs

   -- The incidence of adverse events (AEs) during the RCT was similar between 
      groups with 39 (71%) of 55 participants in the oral octreotide group and 
      26 (70%) of 37 participants in the iSRL group reporting at least one AE. 
      In both treatment groups, most treatment-related AEs were 
      gastrointestinal. 
 
   -- 17 (47%) of 36 participants randomly assigned to iSRL reported injection 
      site reactions via the Acro-TSQ scales at the end of the RCT, and 13 
      (81%) of 16 reported that injection site reactions interfered with daily 
      activities 

About the MPOWERED Phase 3 Trial

The MPOWERED trial was a global, randomized, open-label and active-controlled, 15-month trial intended to support approval of Mycapssa(R) in the European Union. Chiasma/Amryt completed enrollment of 146 adult acromegaly patients into the trial in June 2019, of which 92 patients who were deemed responders to octreotide capsules per the protocol following a six-month run-in were randomized to either octreotide capsules (n=55) or iSRLs (octreotide long-acting release or lanreotide autogel) (n=37). These patients were then followed for an additional nine months in the RCT phase. At the end of the RCT phase patients were provided the option to continue into an open label phase and receive Mycapssa(R).

FDA APPROVED INDICATION AND USAGE

Mycapssa(R) (oral octreotide) delayed-release capsules, for oral use, is a somatostatin analog indicated for long-term maintenance treatment in acromegaly patients who have responded to and tolerated treatment with octreotide or lanreotide.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Mycapssa(R) can cause problems with the gallbladder. Monitor patients periodically. Discontinue if complications of cholelithiasis are suspected.

Blood sugar, thyroid levels, and vitamin B(12) levels should be monitored and treated accordingly.

Bradycardia, arrhythmia, or conduction abnormalities may occur. Treatment with drugs that have bradycardia effects may need to be adjusted.

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