Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Arm A: Debio 4126

During Period 1 (double-blind treatment period), participants will receive an intramuscular (IM) injection of Debio 4126 once every 12 weeks over a total of 36 weeks (3 injections in total). Participants whose acromegaly is not well controlled may receive rescue medication.

Eligible participants (IGF-1 ≤1x ULN on Week 34) will enter Period 2 on Week 36 and receive an open-label Debio 4126 injection once every 12 weeks over a total of 24 to 60 weeks (between 2 and 5 injections in total). Participants with IGF-1 \>1x ULN may receive rescue medication until Week 48, and may become eligible for Period 2 if their IGF-1 is ≤1x ULN.

Group Type EXPERIMENTAL

Debio 4126

Intervention Type DRUG

IM injection, a 12-week extended-release formulation of octreotide

Arm B: Placebo + Debio 4126

During Period 1 (double-blind treatment period), participants will receive an IM injection of placebo once every 12 weeks over a total of 36 weeks (3 injections in total). Participants whose acromegaly is not well controlled may receive rescue medication.

Eligible participants (IGF-1 ≤1x ULN on Week 34) will enter Period 2 on Week 36 and receive an open-label Debio 4126 injection once every 12 weeks over a total of 24 to 60 weeks (between 2 and 5 injections in total). Participants with IGF-1 \>1x ULN may receive rescue medication until Week 48, and may become eligible for Period 2 if their IGF-1 is ≤1x ULN.
