Context: Acromegaly, characterized by excessive GH and insulin-like growth factor-1 (IGF-1), impacts quality of life (QoL) and mortality. Standard of care (SoC; octreotide long-acting repeatable or lanreotide autogel) treatment typically requires healthcare provider administration. CAM2029, a novel subcutaneous octreotide depot with increased bioavailability using FluidCrystal technology, enables self-administration and room- temperature storage. Objective: Assess superiority of CAM2029 vs placebo for biochemical control in patients with controlled acromegaly. Design: 24-week, multinational, randomized, double-blind, phase 3 trial (NCT04076462). Setting: 45 sites; 10 countries. Patients: 72 patients on SoC with biochemical control at screening [IGF-1 <= upper limit of normal (ULN); mean GH <2.5 mu g/L]. Interventions: Patients were randomized 2:1 to once-monthly CAM2029 (n = 48) or placebo (n = 24). Main Outcome Measures: The primary endpoint was proportion of patients with IGF-1 <= ULN (week 22/24 mean), with dose-reduced patients classified as nonresponders; first key secondary endpoint was the same, including dose-reduced responders. The second key secondary endpoint was proportion of patients with IGF-1 <= ULN (week 22/24) and mean GH <2.5 mu g/L (week 24). Results: At week 22/24 (intention-to-treat analysis), CAM2029-treated patients demonstrated superior response rates vs placebo for IGF-1 (72.2% vs 37.5%; risk difference: 34.6, 95% confidence interval: 11.3, 57.9; P = .0018) and combined IGF-1/GH (70.0% vs 37.5%; P = .0035). CAM2029-treated patients had well-controlled symptoms, improved QoL, and treatment satisfaction vs placebo and baseline. CAM2029 was well tolerated; safety was consistent with SoC. Conclusion: CAM2029 provides a convenient and effective treatment option for acromegaly, with superior biochemical control vs placebo. Symptom control, QoL, and satisfaction were improved from baseline SoC.

Abstract
Context: Acromegaly, characterized by excessive GH and insulin-like growth factor-1 (IGF-1), impacts quality of life (QoL) and mortality. Standard of care (SoC; octreotide long-acting repeatable or lanreotide autogel) treatment typically requires healthcare provider administration. CAM2029, a novel subcutaneous octreotide depot with increased bioavailability using FluidCrystal technology, enables self-administration and room- temperature storage. Objective: Assess superiority of CAM2029 vs placebo for biochemical control in patients with controlled acromegaly. Design: 24-week, multinational, randomized, double-blind, phase 3 trial (NCT04076462). Setting: 45 sites; 10 countries. Patients: 72 patients on SoC with biochemical control at screening [IGF-1 <= upper limit of normal (ULN); mean GH <2.5 mu g/L]. Interventions: Patients were randomized 2:1 to once-monthly CAM2029 (n = 48) or placebo (n = 24). Main Outcome Measures: The primary endpoint was proportion of patients with IGF-1 <= ULN (week 22/24 mean), with dose-reduced patients classified as nonresponders; first key secondary endpoint was the same, including dose-reduced responders. The second key secondary endpoint was proportion of patients with IGF-1 <= ULN (week 22/24) and mean GH <2.5 mu g/L (week 24). Results: At week 22/24 (intention-to-treat analysis), CAM2029-treated patients demonstrated superior response rates vs placebo for IGF-1 (72.2% vs 37.5%; risk difference: 34.6, 95% confidence interval: 11.3, 57.9; P = .0018) and combined IGF-1/GH (70.0% vs 37.5%; P = .0035). CAM2029-treated patients had well-controlled symptoms, improved QoL, and treatment satisfaction vs placebo and baseline. CAM2029 was well tolerated; safety was consistent with SoC.
