Background: Somavaratan, a novel long-acting rhGH fusion protein with t1/2>100 h, previously demonstrated clinically meaningful improvements in height velocity (HV) and IGF-I in prepubertal GHD children (Moore JCEM 2016).Objective and hypotheses: To evaluate maintenance of somavaratan treatment effects in the 2nd treatment year.Method: After subcutaneous pediatric doses were evaluated in a single dose PK/PD study (<e...

Background: VRS-317, a novel fusion protein of rhGH, was safe and well tolerated in single dose studies of adults and children with growth harmone deficiency (GHD).Objectives: Conduct a 6-month study to determine the safety, tolerability, height velocity and IGF1 response in GHD children.Methods: 64 subjects were randomized into three arms to evaluate monthly, semi-monthly and weekly dosing.Results: At VRS-31...

Background: VRS-317, a novel fusion protein of rhGH exhibiting delayed clearance, serum half-life generally >100 h, and potential for once monthly dosing, was previously evaluated in a 6-month phase 1b/2a study of weekly, twice monthly or monthly dosing (5.0 mg/kg per month) in prepubertal GHD children (n=64).Objective and hypotheses: We evaluated whether increased VRS-317 dose from 12 to 18 months can offset the decrease in height velocitie...

Background: Use of recombinant human growth hormone (somatropin) is recommended for children with growth hormone deficiency (GHD) to normalize adult height and avoid extreme short stature. Prior research conducted among small study samples, across different study populations and health care systems, has suggested an association between adherence to somatropin and clinical outcomes, including height velocity. There is a need for further research, using real-wor...

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 ...

Growth hormone (GH) stimulates insulin like growth factor I (IGF I) release. IGF-I is the standard biomarker for monitoring GH effects during treatment and to achieve optimal long-term safety, and to a limited extent, monitor efficacy in children with GH deficiency (GHD). The IGF I profile during treatment with a long acting GH (LAGH), such as once weekly somapacitan (Novo Nordisk), differs from the daily GH profile by exhibiting larger peaks and troughs over the dosing interv...

Childhood cancer survivors (CCS), particularly brain cancer survivors, are at risk of developing growth hormone deficiency (GHD) due to hypothalamic-pituitary damage from direct tumor mass effects or treatment. Optimization of testing, long-term treatment, and monitoring during care transition from pediatric to adult endocrinology providers remain challenging. A group of endocrinology experts convened to discuss these challenges, the risks and benefits of GH therapy in CCS wit...

Introduction: Although the safety and effectiveness of recombinant human growth hormone therapy (rhGH) has been reported for several years, the level of consensus on the outcomes that should be reported is unclear. The aim of this systematic review is to study the frequency of reporting of these outcomes in children with GH deficiency (GHD).Methods: A systematic review was performed in Medline, Embase, Cochrane Central R...

Introduction: I. was born at term by emergency caesarean delivery due to foetal distress, by unrelated parents. Birth weight: 2160 g (-3.18 SD), length 41.5 cm (-4.47 SD), head circumference 35.4 cm (0.57 SD). He was admitted in the neonatal intensive care unit (NICU) for the severe growth retardation associated to dysmorphic features. Neonatal screening, echocardiography and brain ultrasound normal. Karyotype: 46,XY.Case present...

6q24 methylation defects are the most common cause of Transient Neonatal Diabetes Mellitus (TNDM). The clinical picture is one of impaired insulin secretion, small for gestational age and diabetes mellitus aged <6 months. This case illustrates the fluctuation between both hyper- and hypoglycaemia that can been seen in 6q24 methylation defects. A term, small for gestational age baby boy was noted to have hypoglycaemia (BSL 1.8 mmol/l) at 1.5 h of life which resolved with or...
