Background: GH treatment currently requires daily sc injections, resulting in suboptimal compliance. A GH regimen with fewer injections may offer patients and caregivers a less arduous option. LB03002 is a novel sustained-release GH formulation for once-weekly dosing. Patients and Methods: GH-deficient, GH-naive prepubertal children were randomized to four groups who received 0.2 mg/kg/wk LB03002 for 12 months, followed by 0.5 mg/kg/wk for another 24 months (n=13); 0.5 mg/kg/wk LB03002 for 36 months (n=13); 0.7 mg/kg/wk LB03002 for 12 months, followed by 0.5 mg/kg/wk for another 24 months (n=13); or daily GH 0.03 mg/kg/d for 24 months, switched to 0.5 mg/kg/wk LB03002 for 12 months (n = 12). Results: Height velocity increased in all groups; the increase was less for the 0.2 mg/kg/wk LB03002 group at 12 (P = 0.008) and 24 months (P = 0.030), with no statistically significant differences at any time for the 0.5 mg/kg/wk and 0.7 mg/kg/wk LB03002 groups, vs. daily GH. Height SD score gain at 12 months was significantly (P = 0.023) less for the 0.2 mg/kg/wk group (1.05 ± 0.38) than daily GH (1.47 ± 0.29), but with no statistically significant difference for the 0.5 mg/kg/wk (1.37 ± 0.39) and 0.7 mg/kg/wk (1.50±0.44) LB03002 groups vs. daily GH. There were no significant differences in height SD score gain between any groups at 24 and 36 months. Bone maturation did not differ for any LB03002 dose compared with daily GH. Serum IGF-I concentrations increased as expected, with no long-term differences between groups. Mean fasting glucose and glycosylated hemoglobin concentrations did not exceed normal ranges for any treatment group at any time. Conclusion: LB03002 at doses of 0.5 mg/kg/wk and 0.7 mg/kg/wk was shown to be effective and safe with once-weekly dosing in GH-deficient children, and 0.5 mg/kg/wk LB03002 was chosen as the optimal dose for long-term assessment.

The weekly sustained-release recombinant human GH formulation LB03002, showed beneficial effects in GH-deficient (GHD) adults in a previous 26-week double-blind study. Prior studies of long-acting GH preparations in adults have only been conducted for 6 or 8 months, so the effects of longer-term use are unknown; this is important to address, as replacement is given for many years in GHD adults. This open-label, 26-week study extension evaluated longer-term safety and efficacy of LB03002 over 52 weeks in adults with GHD who had previously been randomized to GH, and provides additional safety and efficacy data over 26 weeks in the cohort who had previously been randomized to placebo. Of 147 adults with GHD who completed a preceding study, 136 patients continued in this open-label study to receive LB03002 over an additional 26 weeks. This represented a continuation of long-acting GH for 26 weeks in the cohort who took this medication in the prior study (LB03002 Throughout group), and describes the first use of long-acting GH in the cohort that was randomized to placebo in the prior study (Switched to LB03002 group). The LB03002 dose was adjusted according to serum insulin-like growth factor-I (IGF-I) levels. LB03002 treatment demonstrated mean significant decreases from baseline in fat mass (FM) for both 26 (Switched group, P = 0.001) and 52 weeks (Throughout group, P = 0.002) of 1.11 (1.95) kg and 1.06 (3.16) kg, respectively. Prolonged GH treatment was effective in sustaining the increase in lean body mass (LBM), serum IGF-I and IGFBP-3 levels achieved during the first 26 weeks. Long-term treatment with the sustained-release weekly GH preparation over both 26 and 52 weeks in adults with GHD demonstrated a sustained reduction of FM with a favorable safety profile. This study extends prior knowledge about long-acting GH because it reports the most prolonged treatment of adults with any long-acting GH preparation, thereby confirming the value and safety of such agents for long-term GH replacement. © 2012 Springer Science+Business Media, LLC.

Background: A sustained-release recombinant human GH formulation, LB03002, has been recently developed, with pharmacokinetics and pharmacodynamic activity appropriate for once-weekly administration. LB03002 is a long-acting GH that is administered once a week by sc injection. Objective: This study evaluated efficacy and safety of LB03002 in adult patients with GH deficiency. Patients and Methods: A total of 152 patients were randomized to receive LB03002 or placebo once weekly for 26 wk. Changes in body composition were evaluated from DXA (dual-energy x-ray absorptiometry). IGF-I was assessed at each study visit. Safety was assessed from adverse events, glucose homeostasis, and antibody development. Results: IGF-I increased significantly (P < 0.001) with LB03002 and remained unchanged with placebo. Mean fat mass (FM) decreased by 1.052 kg [95% confidence interval (CI) = -1.614 to -0.491] in the LB03002 group vs. an increase of 0.570 kg (95% CI = -0.205-1.345) in the placebo group; treatment difference was 1.622 kg (95% CI = -2.527 to -0.717; P < 0.001). FM change was mainly due to decreased trunk fat. Least square mean treatment difference was 1.032 kg (95% CI = -1.560 to -0.515; P < 0.001). LBM (lean body mass) was significantly increased with LB03002 vs. placebo (least square mean difference was 1.393 kg; 95% CI = 0.614-2.171; P < 0.001). No concerning safety issues arose during the study. Conclusions: Weekly GH replacement with the sustained-release preparation LB03002 in adults significantly reduced FM over 6 months and was well tolerated. Copyright © 2011 by The Endocrine Society.

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: Weconducted a phase III, 12-month, multinational, randomized, open-label, comparatorcontrolled 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 11.63 ± 2.60 cm/y with LB03002, and 11.97 ± 3.09 cm/y with daily GH, with increases from baseline of 8.94 ± 2.91 and 9.04 ± 3.19 cm/y, respectively. Theleast square mean HV difference for LB03002 - daily GH was - 0.43 cm/y (99% confidence interval, - 1.45 to 0.60 cm/y). Mean HV also remained above baseline in year 2 (8.33 ± 1.92 cm/y in the LB03002 throughout group, and 7.28 ± 2.34 cm/y in the switched to LB03002 group). Injection site reactions occurred more frequently in LB03002-treated patients but were considered mild to moderate in >90% of cases. Conclusions: Growth response with once-weekly LB03002 in GH-deficient children is comparable to that with daily GH, achieving expected growth rates for 24 months. Once-weekly LB03002 is a strong candidate for long-term GH replacement in GH-deficient children. (J Clin Endocrinol Metab 99: 126-132, 2014). © Copyright 2014 by The Endocrine Society.
