Background: CTP-modified hGH (MOD-4023) has been developed for once weekly administration in GH deficient (GHD) adults and children. Immunogenicity samples of once-weekly s.c. administration of MOD-4023 were detected for the presence of binding and neutralizing anti-MOD-4023 Ab’s in pediatric Phase 2 study.Objective and hypotheses: During the first year of the study, 53 pre-pubertal GHD children were treated with once-weekly s.c. injections of one o...

Background: OPKO Biologics is developing MOD-4023, a long-acting growth hormone (GH), intended for weekly dosing for the treatment of idiopathic GH deficiency in children. At ESPE2015, we presented pharmacokinetic (PK) and pharmacodynamic (PD, based on IGF-1) models for weekly MOD-4023 administration in children aged 3–11 years. These models confirm that IGF-1 (and IGF-1 SDS) varies during the dosing interval. One critical clinical and research issue is when to optimally ...

Background: OPKO Biologics is developing MOD-4023, a long-acting growth hormone (GH), intended for weekly dosing for the treatment of idiopathic GH deficiency in children. At ESPE2015, we presented pharmacokinetic (PK) and pharmacodynamic (PD, based on IGF-1) models for weekly MOD-4023 administration in children aged 3–11 years. Those models were based on data collected during the ‘PKPD period’ (the second steady state dose of MOD-4023) and monthly values during...

Background, objective, and hypotheses: OPKO Biologics has produced a long-acting human GH (hGH), MOD-4023, containing copies of a naturally-occurring C-terminal peptide (CTP) to markedly increase GH’s in vivo residence. We describe the construction and validation of a pharmacokinetic (PK)/pharmacodynamics (PD) model to characterise the relationship between MOD-4023 dose, MOD-4023 serum concentrations (Cserum), and IGF1 responses in healthy adults, GH-deficient (G...

Background: Daily injections are currently required for growth hormone (GH) replacement therapy, which may cause poor compliance, inconvenience and distress for patients. MOD-4023 is a CTP-modified human GH (hGH) developed for once-weekly administration in growth hormone deficient (GHD) adults and children.Objective and hypotheses: In the present Phase 2 study, the safety and tolerability of once-weekly subcutaneous (SC) administration of MOD-4023 were a...

Background: Growth hormone (GH) replacement therapy currently requires daily injections, which may cause poor compliance, inconvenience and distress for patients. CTP-modified hGH (MOD-4023) has been developed by OPKO Biologics for once-weekly administration in growth hormone-deficient (GHD) adults and children.Objective and hypotheses: The 24-month efficacy of once-weekly subcutaneous (SC) administration of MOD-4023 was evaluated in a Phase 2 study in G...

Background: GH replacement therapy currently requires daily injections, which may cause poor compliance, inconvenience and distress for patients. CTP-modified hGH (MOD-4023) is being developed for once-weekly administration in GH deficient (GHD) children. In the present study the longer term pharmacokinetics (PK) and pharmacodynamics (PD) profile of MOD-4023 in GHD naïve children was assessed.Objective and hypotheses: To assess the long acting prope...

Objective: GH replacement therapy currently requires daily injections, which may cause poor compliance, inconvenience and distress for patients. CTP-modified hGH (MOD-4023) has been developed for once-weekly administration in GH deficient (GHD) adults and children. Pharmacokinetics (PK), pharmacodynamics, (PD) efficacy and safety analysis of weekly treatment with MOD-4023 in GHD naïve children was performed and compared to daily hGH.Design and metho...

Objective and hypotheses: To compare the PK/PD, safety, efficacy, and tolerability of three doses of once-weekly MOD-4023 to that of a daily recombinant human GH (rhGH) formulation in pre-pubertal children with growth failure due to GH deficiency (GHD).Method: The randomised, controlled phase 2 study was conducted in 53 pre-pubertal, hGH-naïve GHD children randomised to receive one of three MOD-4023 doses as a once-weekly s.c. injection (0.25, 0.48,...
