Conclusions There is no evidence to support differences in the effects of long-acting GH compared with those of daily GH .
Purpose Long-acting growth hormone ( GH ) has been developed to address the noncompliance and decreased efficacy associated with daily GH injections .
We aim ed to evaluate the efficacy and safety of long-acting GH replacement therapy in children with short stature .
MOD-4023, a long-acting carboxy-terminal peptide-modified human growth hormone: results of a Phase 2 study in growth hormone-deficient adults
Objective Growth hormone ( GH ) replacement therapy currently requires daily injections , which may cause distress and low compliance . C-terminal peptide (CTP)-modified growth hormone ( MOD-4023 ) is being developed as a once-weekly dosing regimen in patients with GH deficiency ( GHD ) . This study ’s objective is to evaluate the safety , pharmacokinetics ( PK ) , pharmacodynamics ( PD ) and efficacy of MOD-4023 administered once-weekly in GHD adults . Design 54 adults with GHD currently treated with daily GH were normalized and r and omized into 4 weekly dosing cohorts of MOD-4023 at 18.5 % , 37 % , 55.5 % or 123.4 % of individual cumulative weekly molar hGH dose . The study included 2 stages : Stage A assessed the effectiveness and PK/PD profiles of the 4 dosing regimens of MOD-4023 . Stage B was an extension period of once-weekly MOD-4023 administration ( 61.7 % molar hGH content ) to collect further safety data and confirm the results from Stage A. Results Dose-dependent response was observed for both PK and PD data of weekly MOD-4023 treatment . Insulin-like growth factor I ( IGF-I ) SDS levels were maintained within normal range . The 18.5 % cohort was discontinued due to low efficacy . MOD-4023 was well tolerated and exhibited favorable safety profile in all dose cohorts . The reported adverse events were consistent with known GH-related side effects . Conclusions Once-weekly MOD-4023 administration in GHD adults was found to be clinical ly effective while maintaining a favorable safety profile and may obviate the need for daily injections . Weekly GH injections may improve compliance and overall outcome . The promising results achieved in this Phase 2 study led to a pivotal Phase 3 trial , which is currently ongoing
