A 24-Week Safety, Efficacy, Pharmacokinetic Study of Teduglutide in Japanese Subjects With Short Bowel Syndrome Who Are Dependent on Parenteral Support
The objectives of this clinical study are to evaluate the safety, efficacy, and pharmacokinetics (PK) of teduglutide in Japanese participants with short bowel syndrome (SBS) who are dependent on parenteral nutrition/intravenous (PN/IV) over a 24-week treatment period.
Sex: All, ages: 16 Years to any
Inclusion Criteria:
1. Ability to voluntarily provide written, signed, and informed consent to participate in the study.
2. Male or female 16 years of age or older at the time of signing informed consent.
3. Intestinal failure due to short bowel syndrome (SBS) as a result of major intestinal resection (example, due to injury, volvulus, vascular disease, cancer, Crohn's disease) that resulted in at least 12 continuous months of parenteral nutrition/intravenous (PN/IV) dependence at the time of informed consent.
4. Parenteral nutrition requirement of at least 3 times per week during the week before the screening visit and during the 2 weeks prior to the baseline visit.
5. Stable PN/IV requirement for at least 4 consecutive weeks immediately prior to the start of teduglutide treatment. Stability is defined as: a. Actual PN/IV usage is similar to prescribed PN/IV; b. Baseline (Visit 2) 48-hour oral fluid intake and urine output (I/O) volumes fall within +/- 25 percent (%) of the respective 48-hour I/O volumes at the last optimization visit; c. Urine output volume should NOT fall below 2 liter (L) and should not exceed 4 L per 48 hours at the last optimization visit, the stabilization visit, and the baseline visit.
6. For participants with a history of Crohn's disease, clinical remission for at least 12 weeks prior to the baseline visit as demonstrated by clinical assessment, which may include procedure-based evidence of remission.
7. Females of childbearing potential must agree to comply with the contraceptive requirements of the protocol.
8. An understanding, ability, and willingness to fully comply with study procedures and restrictions.
Exclusion Criteria:
1. Participation in a clinical study using an experimental drug within 30 days or 5.5 halflives, whichever is longer, prior to screening, or concurrent participation in any other clinical study.
2. Use of glucagon-like peptide (GLP)-2 or human growth hormone or analogs of these hormones within the past 6 months.
3. Use of octreotide, GLP-1 analogs, dipeptidyl peptidase-IV inhibitors, or enteral glutamine within 30 days.
4. Previous use of teduglutide.
5. Participants with active inflammatory bowel disease (IBD) or participants with IBD who received a change in immunosuppressant therapy (example, azathioprine, anti- tumor necrosis factor (TNFs)) within the past 6 months.
6. Intestinal malabsorption due to a genetic condition, such as cystic fibrosis, microvillus inclusion disease, familial adenomatous polyposis, etc.
7. Chronic intestinal pseudo-obstruction or severe dysmotility.
8. Clinically significant intestinal stenosis or obstruction, or evidence of such on upper gastrointestinal (GI) series with small bowel follow-through, within the past 6 months.
9. Major GI surgical intervention, including bowel lengthening procedures, within the past 3 months (insertion of feeding tube or endoscopic procedure is allowed).
10. Unstable cardiac disease, (example, congestive heart failure, cyanotic disease, or congenital heart disease).
11. Moderate or severe renal impairment, defined as creatinine clearance less than (<) 50 millilitre (ml)/ minute (min).
12. Currently diagnosed with cancer or a history of any cancer except surgically curative skin cancer within the past 5 years.
13. Severe hepatobiliary disease including: a. Total bilirubin level greater than or equal to (>=) 2 times the upper limit of normal (ULN); b. Aspartate aminotransferase (AST) >=5 times ULN; c. Alanine aminotransferase (ALT) >=5 times ULN.
14. Active clinically significant pancreatic disease, including clinical signs of pancreatitis associated with elevations in serum amylase or lipase >=2 times ULN.
15. More than 4 SBS-related or PN/IV-related hospital admissions (example, central line associated bloodstream infection, bowel obstruction, severe fluid/electrolyte disturbances) within the past 12 months.
16. Unscheduled hospitalization within 30 days prior to screening.
17. Pregnant or lactating female.
18. Any condition or circumstance that in the investigator's opinion put the participant at any undue risk, prevent completion of the study, or interfere with analysis of the study results.
