Brief summary
The primary purpose of this study is to assess the effect of Debio 4126 in the maintenance of the levels of insulin-like growth factor 1 (IGF-1) ≤1x upper limit of normal (ULN) in the double-blind period (Period 1) in comparison to placebo at week 36.
Interventions
IM injection, a 12-week extended-release formulation of octreotide
IM injection of mannitol suspension
