E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Short Bowel Syndrome (SBS) refers to the clinical situation whereby a significant reduction in the absorptive capacity of the intestine results from inadequate anatomical or functional length of residual small intestine following surgical resection. These patients are highly prone to malnutrition, diarrhea, and dehydration due to the reduced intestinal capacity to absorb macronutrients, water and electrolytes (1-8). |

E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this clinical study is to evaluate the efficacy, safety, tolerability, and pharmacokinetics (PK) of teduglutide compared with placebo in subjects with PN (Parenteral Nutrition)-dependent SBS. The primary objective is to compare the percentage of subjects treated with teduglutide versus placebo who demonstrate a response at week 20, and who maintain that response through week 24. A response in this study is defined as the achievement of at least a 20% reduction from baseline in weekly PN volume. |
|
E.2.2 | Secondary objectives of the trial |
The secondary efficacy objectives are to evaluate changes in volume of PN, frequency of PN, frequency of iv catheter access, and to evaluate quality of life and utilization of healthcare resources. Additional variables to be evaluated are changes from baseline in parathyroid hormone (PTH), bone markers, bone mineral density (BMD), plasma citrulline, and intestinal mucosal villus height and crypt depth. At selected centers, additional objectives are to evaluate changes in the enteral absorption of gastrointestinal fluid (wet weight), calories, nitrogen, fat, carbohydrate, sodium, magnesium, calcium, and potassium. The safety and tolerability of teduglutide treatments compared with placebo will be assessed. The population PK of teduglutide in subjects with PN-dependent SBS will also be determined. |

E.4 | Principal exclusion criteria |
Subjects who meet any of the following criteria will be excluded: 1.History of cancer or clinically significant lymphoproliferative disease with fewer than 5 years documented disease-free state. This does not include resected cutaneous basal or squamous cell carcinoma, or in situ cervical cancer. 2.History of alcohol or drug abuse (within previous year) 3.Participation in a clinical study within 30 days prior to signing the ICF, or concurrent participation in any clinical study 4.Clinically significant laboratory abnormalities at the time of randomization 5.Previous use of teduglutide (ALX-0600) 6.Prior use of native GLP-2 within 3 months of screening visit 7.Hospital admission within 1 month prior to screening visit 8.Pregnant or lactating women 9.Any condition or circumstance, which in the investigator’s opinion would put the subject at any undue risk, prevent completion of the study, or interfere with analysis of the study results 10.Presence of excluded disease. The following is a table of excluded disease states arranged by body systems: Related to SBS Radiation enteritis Scleroderma Celiac disease Refractory or tropical sprue Pseudo-obstruction
Gastrointestinal (GI) Active inflammatory bowel disease (IBD) Pre-malignant or malignant change in colonoscopy biopsy or polypectomy Surgery scheduled within the time frame of the study
Immune Human immunodeficiency virus (HIV) positive test Immunological disorders Possible allergies to teduglutide or its constituents
Cardiovascular, respiratory, renal, endocrine, hepatic, or CNS Significant active, uncontrolled, untreated systemic diseases
11. Failure to adhere to required washout periods. The following table contains lists of certain medications, arranged by the periods of time that must have transpired after stopping them before the first dose of teduglutide in this study. Use of iv insulin is not excluded.
