Overview
Brief Summary
The purpose of this study is to determine if an investigational treatment (teduglutide) is safe and effective in Japanese children (age 4 months through 15 years of age) with SBS who are dependent on parenteral support. This study will also evaluate how teduglutide moves through the body (pharmacokinetics) and how it affects the body (pharmacodynamics).
Investigators
Eligibility Criteria
Inclusion Criteria
- •Informed consent by a parent or guardian prior to any study-related procedures
- •When applicable, informed assent (as deemed appropriate by the Institutional Review Board) by the participant prior to any study-related procedures
- •Male or female infant 4 to \<12 months corrected gestational age or child or adolescent aged 1 year through 15 years
- •Current history of SBS as a result of major intestinal resection (eg, due to necrotizing enterocolitis, midgut volvulus, intestinal atresia, or gastroschisis)
- •Short bowel syndrome that requires PN/IV support that provides at least 30% of caloric and/or fluid/electrolyte needs
- •Stable PN/IV support, defined as:
- •For infants 4 to \<12 months corrected gestational age: Inability to significantly reduce PN/IV support, usually associated with minimal or no advance in enteral feeds (ie, 10% or less change in PN or advance in feeds) for at least 1 month prior to and during screening, as assessed by the investigator.
- •For children 1 to 15 years of age:
- •Inability to significantly reduce PN/IV support, usually associated with minimal or no advance in enteral feeds (ie, 10% or less change in PN or advance in feeds) for at least 3 months prior to and during screening, as assessed by the investigator.
- •Transient instability for events such as interruption of central access or treatment of sepsis is allowed if the PN/IV support returns to within 10% of baseline prior to the event.
Exclusion Criteria
- •Participants who are not expected to be able to advance oral or tube feeding regimens
- •Serial transverse enteroplasty or any other bowel lengthening procedure performed within 3 months of screening
- •Known clinically significant untreated intestinal obstruction contributing to feeding intolerance and inability to reduce parenteral support
- •Unstable absorption due to cystic fibrosis or other known DNA abnormalities (eg, Familial Adenomatous Polyposis, Fanconi-Bickel syndrome)
- •Severe, known dysmotility syndrome such as pseudo-obstruction or persistent, severe, active gastroschisis-related dysmotility; that is the primary contributing factor to feeding intolerance and inability to reduce parenteral support, prior to screening. Dysmotility is defined as severe if it is expected to limit the advancement of enteral feeding.
- •Evidence of clinically significant obstruction on the most recent upper GI series done within 6 months prior to screening.
- •Major GI surgical intervention including significant intestinal resection within 3 months prior to screening (insertion of feeding tube, anastomotic ulcer repair, minor intestinal resections \<=10 centimeter (cm), or endoscopic procedure is allowed)
- •Unstable cardiac disease or congenital heart disease or cyanotic disease, with the exception of participants who had undergone ventricular or atrial septal defect repair, and patent ductus arteriosus (PDA) ligation
- •History of cancer or clinically significant lymphoproliferative disease, not including resected cutaneous basal or squamous cell carcinoma, or in situ nonaggressive and surgically resected cancer. Participants with known cancer predisposition syndrome, such as juvenile polyposis or Beckwith-Wiedemann syndrome, or first degree relative with early onset of GI cancer (including hepatobiliary and pancreatic cancer) will also be excluded.
- •Pregnant or lactating female participants
