E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the long-term safety of glepaglutide treatment in short bowel syndrome (SBS) patients
|
|
E.2.2 | Secondary objectives of the trial |
- To evaluate the long-term efficacy of glepaglutide treatment in SBS patients - To evaluate the long-term immunogenicity of glepaglutide and its impact on pharmacokinetics (PK), efficacy, and safety in SBS patients - To evaluate quality of life for SBS patients treated with glepaglutide |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Pharmacokinetics Profile Sub-Study At Visit 7 (i.e. after 12 weeks of trial drug treatment), approximately 45 patients will be included in more extensive PK sampling. This is done to provide sufficient information about the PK-profile of glepaglutide and its primary active metabolites in SBS patients. The week prior to the PK sampling the patients must have been compliant to the planned dosing. The patients are planned to be from the lead-in trial from selected sites. The aim is to include about 15 patients allocated to twice weekly and about 30 patients allocated to once weekly. The PK profile sub-study is optional and patients can participate in the main trial without participating in the sub-study. As each PK sample contains 2 mL of blood, this is resulting in additional 14 mL blood drawn for PK-profile purposes. The PK profile sub-study must start on a day of trial drug administration, and the vial must be taken after the first PK sampling (0 hour). |
|
E.3 | Principal inclusion criteria |
Patients rolling over from the lead-in trial: The patient must meet all of the following inclusion criteria: 1. Signed informed consent 2. Either of the following: a) Completed the full Treatment phase of the lead-in trial (ZP1848-17111), regardless of treatment adherence. OR b) Eligible based on the same inclusion/exclusion criteria as in the lead-in trial (patients may be directly screened into this trial) Patients screened directly to the Extension Trial The patient must meet all of the following inclusion criteria: 1. Informed consent obtained before any trial-related activity. 2. Age ≥ 18 years and ≤ 90 years at Screening. 3. Diagnosis of SBS defined as remaining small bowel in continuity of estimated less than 200 cm [equal to 79 inches] and with the latest intestinal resection being at least 6 months prior to Screening and considered stable with regard to PS need. No restorative surgery planned in the trial period. 4. Requiring PS at least 3 days per week. 5. Willing to adhere to an individual pre-defined drinking menu during 48-hours measuring intervals. 6. Willing to maintain a stable weight (± 5%) for the duration of the trial (24 weeks). 7. Having: a. A stoma Or b. Colon-in-Continuity (CiC) with documented colonoscopy performed during Screening and which does not give rise to any safety concerns. Note: A colonoscopy performed within 6 months prior to Screening and not giving rise to any safety concerns is acceptable. For patients with a remnant colon, which is not connected to the passage of foods and is thereby dormant, a computerized tomography (CT) scan or magnetic resonance imaging (MRI) (if standard of care at site) will suffice at the discretion of the Investigator. 8. Having: a) a stoma Or b) colon-in-continuity (CiC) and able to separate stool and urine during the 48 hours measuring intervals.
