assessed by the primary endpoint, intermittent self-
measured plasma glucose. However, dasiglucagon
treatment resulted in a 40–50% reduction in hypoglycemia
compared to SOC alone, when assessed by blinded
continuous glucose monitoring.
The Phase 3 trial 17106 (ClinicalTrials.gov ID: NCT03941236)
is evaluating the long-term safety of dasiglucagon in 42 of
the 44 children older than 1 month with CHI who completed
either of the Phase 3 trials 17103 or 17109.
Glepaglutide (long-acting GLP-2 analog) for short bowel
syndrome (SBS)
Second quarter 2023 update:
• Presentation of EASE-1 results at the ASPEN 2023
Nutrition Science & Practice Conference in April 2023
and Digestive Diseases Week in May 2023.
• Completion of interim analyses for the EASE-2, EASE-3
and EASE-4 clinical trials of glepaglutide in patients with
short bowel syndrome and intestinal failure to support
regulatory submission expected in the second half of
2023.
Background:
Glepaglutide is a long-acting GLP-2 analog that is stable in
aqueous solution and can be administered as a ready-to-use
liquid formulation. Zealand is developing glepaglutide as a
ready-to-use, fixed dose product designed for
subcutaneous delivery via auto-injector for the potential
treatment of SBS. The Phase 3 program includes four clinical
trials evaluating the potential for glepaglutide to reduce or
eliminate the need for parenteral support in patients with
SBS.
EASE-1 is a randomized, double-blind Phase 3 trial that
enrolled a total of 106 SBS patients with intestinal failure who
were dependent on parenteral support for at least three days
per week. Patients were evenly randomized to receive
treatment with 10 mg glepaglutide administered either once
or twice weekly, or placebo. The primary endpoint in the trial
was the absolute change in weekly parenteral support
volume from baseline at 24 weeks.
In EASE-1, glepaglutide given twice weekly significantly
reduced the total weekly volume of parenteral support at 24
weeks as compared to placebo (p=0.0039). When
administered once weekly, glepaglutide treatment also
resulted in a numeric reduction in weekly parenteral
support, however this did not achieve statistical significance.
At 24 weeks, the average reduction in parenteral support
from baseline was 5.13 Liters/week for patients treated with
glepaglutide twice weekly and was 3.13 Liters/week for
patients treated with glepaglutide once weekly. Placebo
treatment resulted in a reduction in parenteral support of
2.85 Liters/week. Clinical response, defined as a patient
achieving at least 20% reduction in weekly parenteral
support volume from baseline at both 20 and 24 weeks, was
significantly higher with twice weekly glepaglutide
compared to placebo (p=0.0243). Among patients receiving
glepaglutide twice weekly, 65.7% achieved a clinical
response, whereas 45.7% and 38.9% of patients achieved a
clinical response in the once weekly and placebo treatment
groups, respectively.
In the twice weekly dosing group, 14% of patients (n=5) were
completely weaned off parenteral support (enteral
autonomy). In total, 9 patients treated with glepaglutide
achieved enteral autonomy, while no placebo-treated
patients were able to discontinue parenteral support.
Glepaglutide appeared to be safe and was well-tolerated in
the trial. The most frequently reported adverse events were
injection site reactions and gastrointestinal events. These
results were presented at the ASPEN 2023 Nutrition Science
& Practice Conference in April 2023 and Digestive Diseases
Week in May 2023.
In total, 102 of 106 participating patients completed EASE-1,
of which 96 continued into the ongoing two-year, long-
term safety and efficacy extension trial, EASE-2. EASE-2 is a
randomized, double-blind trial in which SBS patients
continued their assigned treatment from EASE-1 with
glepaglutide 10 mg once or twice weekly. Patients who
received placebo in EASE-1 were re-randomized to
treatment with either glepaglutide 10 mg once or twice
weekly. In an interim analysis conducted at six months,
clinical response to glepaglutide across the key efficacy
endpoints was generally maintained or showed continued
improvement. Data also demonstrated that additional
patients on both doses weaned off parenteral support
successfully.
Patients who complete EASE-2 are eligible to participate in
EASE-3, evaluating glepaglutide administered once weekly
using an auto-injector. An interim analysis of EASE-3,
conducted with the first 43 patients rolled over from EASE
2, showed that the reduction in prescribed PS was generally
maintained.
Glepaglutide appeared to be safe and well-tolerated in
EASE-2 and EASE-3, with a profile consistent with that
observed in EASE-1. Both EASE-2 and EASE-3 long-term
extension trials are ongoing.
In addition, EASE-4 is a Phase 3b trial to assess long-term
effects of glepaglutide on intestinal fluid and energy uptake.
Zealand has completed the interim analysis of the trial and
expects to present results from this study at a future
scientific conference.

EASE Phase 3 program to form the basis of an NDA
