Background: Growth hormone (GH) replacement therapy usually requires daily subcutaneous (s.c.) injections that can be burdensome for patients and their caregivers. Long-acting GH formulations aim to establish a less burdensome dosing regimen that is as safe and efficacious as daily GH to potentially improve adherence and clinical outcomes. Somapacitan, a long-acting reversible albumin-binding GH derivative, is in development for once-weekly s.c. administration...

Daily subcutaneous (s.c.) injections of growth hormone (GH) to treat GH deficiency (GHD) in children is burdensome for both patients and caregivers. Somapacitan (Novo Nordisk) is a long-acting reversible albumin-binding human GH derivative in development for once-weekly s.c. administration in children with GHD, and aims to overcome the treatment burden of daily injections. REAL4 is a multi-national, randomised, open labelled phase 3 trial with a 52-week main phase followed by ...

Introduction: Lonapegsomatropin (SKYTROFA, TransCon hGH), a prodrug of somatropin administered once-weekly, is approved for the treatment of pediatric growth hormone deficiency (GHD) by the Food and Drug Administration and European Commission. In the pivotal 52-week phase 3 heiGHt trial and 26-week fliGHt trial (enrolled treatment-naïve and treatment-experienced participants, respectively), lonapegsomatropin demonstrated safety and efficacy in children wi...

Somapacitan (Novo Nordisk A/S) is a long-acting GH derivative, approved for once-weekly administration in children and adults with GHD. IGF-I is monitored and includes a fraction bound to binding proteins, e.g., IGF binding protein-3 (IGFBP-3). The IGF-I/IGFBP-3 molar ratio can be used as surrogate marker for freely circulating bioactive IGF-I. REAL4 is a randomised, open-label, multi-national phase 3 trial (NCT03811535) with a 52-week main phase and a 3-year extension (week 5...

Lonapegsomatropin (TransCon hGH) is an investigational once-weekly prodrug of somatropin for the treatment of GHD. Previous trials in treatment-naïve (52-week heiGHt Trial) and treatment-experienced children (26-week fliGHt Trial) have reported the efficacy and safety of lonapegsomatropin. Subjects were eligible to enter the open-label extension enliGHten Trial, which continues to evaluate weekly lonapegsomatropin in pediatric GHD. In heiGHt, treatment-naïve subjects...

Objectives: Children with growth hormone deficiency (GHD) are usually treated with once-daily injections of recombinant human growth hormone (rhGH). Somatrogon is a long-acting rhGH (LAGH) approved in the EU and other countries for once-weekly treatment of children with short stature. The Pfizer Registry of Outcomes in Growth hormone RESearch (PROGRES) study will assess the long-term safety and effectiveness of once-weekly somatrogon and once-daily rhGH prepar...

Introduction: The Global Registry For Novel Therapies In Rare Bone & Endocrine Conditions (GloBE-Reg, https://globe-reg.net/) project was launched in 2022 with the aim of supporting studies that focus on effectiveness and long-term safety of specific therapies. The project’s initial focus has been on recombinant human growth hormone therapy (rhGH) given that there are existing gaps in knowledge with the introdu...
