| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| 1. Signed informed consent for this trial prior to any trial specific assessment. 2. Male and female subjects with SBS-IF, receiving parenteral support (PS), secondary to surgical resection of the small intestine with either stoma or colon-in-continuity (CIC).
 3. Subject must require PS at least 3 days per week and be considered stable.
 4. No planned restorative surgery or major intestinal surgery (more than 10% intestinal resection or surgery that changes anatomy group i.e. stoma or CIC), in the trial period.
 5. Age ≥18 years at Screening.
 
 |  | 
| E.4 | Principal exclusion criteria | 
| 1.Pregnancy and/or lactation. 2.Major abdominal surgery in the last 6 months prior to screening visit.
 3.History of cancer (including colon carcinoma) or clinically significant lymphoproliferative disease within ≤5 years, except for adequately treated basal cell skin cancer.
 4.Active inflammatory bowel diseases (IBD) or underlying condition that requires new drug treatment or regimen changes in the previous 3 months.
 5.Evidence of decompensated heart failure.
 6.Evidence of severe renal or hepatic impairment.
 7.Any treatment of greater than 2 weeks of growth factors such as growth hormone (GH), native GLP-2, GLP-1, short acting GLP-2 analogues (e.g., teduglutide) or GLP-1 analogues in the previous 3 months before randomization or treatment with longer acting experimental GLP-2 analogues should be discussed with the Investigator.
