24-Month Use of Once-Weekly GH, LB03002, in Prepubertal Children With GH Deficiency

Background: Sustained-release GH formulations may provide a strategy for improving treatment compliance and persistence in GH-deficient patients. Objective: The aim of the study was to examine efficacy and safety of LB03002, a sustained-release GH formulation for once-weekly administration. Design: We conducted a phase III, 12-month, multinational, randomized, open-label, comparator-controlled trial with a 12-month uncontrolled extension. Patients: Prepubertal GH treatment-naive GH-deficient children (mean age, 7.8 y) participated in the study. Intervention: We administered once-weekly LB03002 (n = 91) or daily GH (n = 87) for 1 year, followed by once-weekly LB03002 for all patients for another year (LB03002 throughout, n = 87; switched to LB03002, n = 80). Outcome Measures: Height, height velocity (HV), IGF-1, GH antibodies, and adverse events were determined throughout. Primary analysis was noninferiority of LB03002 vs daily GH at 1 year by analysis of covariance. Results: Mean ± SD HV during year 1 was...
