Assessing Debio 4126 for treating acromegaly in patients on somatostatin analogs

Official title: A Phase 3 Randomized 3-arm Trial (Double-blind Debio 4126, Placebo Control, and Open-label Debio 4126), to Assess the Efficacy and Safety of Debio 4126, a 12-week Octreotide Formulation, in Patients With Acromegaly Previously Treated With Somatostatin Analogs

Run by Debiopharm International SA · NCT06930625 · Data updated 2026-11-12

This study is testing if a new treatment called Debio 4126 can help people with acromegaly who are already on somatostatin analogs keep their IGF-1 levels in check better than a placebo.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who have been on stable doses of octreotide or lanreotide for at least 6 months and have controlled IGF-1 levels.

Probably not a fit

Patients with recent pituitary surgery, uncontrolled diabetes, or those who have received certain other treatments for acromegaly may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the efficacy and safety of Debio 4126 in maintaining insulin-like growth factor 1 (IGF-1) levels in patients with acromegaly who have been treated with somatostatin analogs. Participants will be randomly assigned to receive either Debio 4126 or a placebo in a double-blind manner over a 36-week period. The primary outcome is to determine if Debio 4126 can effectively keep IGF-1 levels at or below the upper limit of normal compared to placebo. The study aims to provide insights into a new treatment option for patients with acromegaly.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective management option for patients with acromegaly, potentially improving their quality of life.

How similar studies have gone: Other studies have shown promise in treating acromegaly with similar approaches, but the specific efficacy of Debio 4126 is being evaluated for the first time.
