Energy Balance & Weight Loss in Craniopharyngioma-related or Other Hypothalamic Tumors in Hypothalamic Obesity
Completed · Phase 3 · Has a placebo group
Conditions studied: Hypothalamic Obesity
In brief
The proposed multicenter study will test the effect of glucagon-like peptide (GLP)-1 agonist exenatide once weekly extended-release (ExQW, Bydureon®) on clinical outcomes and metabolic parameters in a double-blind, placebo-controlled 36 week randomized trial with an 18 week open label extension. Following baseline testing, 48 patients will be randomly assigned with equal allocation to ExQW or matching placebo injection for 36 weeks, followed by an 18 week open label extension during which all patients receive ExQW. Changes of weight status, body composition, free-living total daily energy expenditure (EE) by doubly labeled water (DLW), activity by acetimetry, energy intake (questionnaires and food diary), as well as glucose tolerance and hormonal parameters of energy homeostasis and insulin resistance will be assessed before treatment and at the end of the placebo-controlled phase (week 36). Activity, metabolic outcomes, energy intake will be also assessed at study week 18 (mid treatment of randomized study), as well as week 54 (end of open label treatment).
