Once-Weekly Somapacitan vs Daily GH in Children with GH Deficiency: The Randomized Phase 3 REAL 4 Trial

Miller Bradley , Blair Joanne , Højby Michael , Böttcher Volker , Juul Kildemoes Rasmus , Maniatis Aristides , Beck Bang Rikke , Mori Jun , Polak Michel , Stagi Stefano , Horikawa Reiko

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...

GH replacement therapy with once-weekly somapacitan in children with GH deficiency is effective and well-tolerated: 2-year results from REAL4

Miller Bradley , Blair Joanne , Højby Rasmussen Michael , Maniatis Aristides , Mori Jun , Böttcher Volker , Bang Rikke , Polak Michel , Horikawa Reiko

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 ...

de Gouveia Buff Passone Caroline , Giani Elisa , Vaivre-Douret Laurence , Karayawasam Dulandjalee , Berdugo Marianne , Garcin Laure , Beltrand Jacques , Marques Bernardo Wanderley , Polak Michel

Background: In monogenic diabetes due to KCNJ11 and ABCC8 mutations that impair KATP- channel function, sulphonylureas improve long-term glycaemic control. Although KATP channels are extensively expressed in the brain, the effect of sulphonylureas on neurological function has varied widely. We evaluated published evidence about potential effects of sulphonylureas on neurological features, especially epilepsy, cognition, motor function and muscular tone, visuo-...

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of short stature. Diagnosis is based on low basal IGF1 concentration, short stature, normal or elevated growth hormone concentrations and absence of any secondary causes of growth failure. Thanks to advances in next-generation sequencing (NGS) technologies, genetic etiology of SPIGF1D is expanding.Objectives: • Identify th...

Thyroid Dysgenesis: Exome-Wide Analysis Identifies Rare Variants in Genes Involved in Thyroid Development and Cancer

Context: Congenital hypothyroidism from thyroid dysgenesis (CHTD) is mainly a sporadic and non-syndromic condition occurring in 1:4,000 live births. In contrast to rare cases of syndromic monogenic CHTD, non-syndromic (NS) CHTD shows low familial recurrence risk (~2%) and low concordance rate between MZ twins, suggesting a two-hit scenario combining post-zygotic events with either a de novo monogenic mutation or incomplete penetrance of polyg...

Efficacy and Safety of Growth Hormone (GH) in the Treatment of Children with Hypochondroplasia (HCH): Comparison with a Historical Cohort of Untreated Children with HCH

Pinto Graziella , Samara-Boustani Dinane , Viaud Magali , Cormier-Daire Valérie , Lopez Yeriley , Fresneau Laurence , Piketty Marie , Claude Pineau Jean , Polak Michel

Hypochondroplasia (HCH) is a skeletal dysplasia, mainly caused by mutations in the fibroblast growth factor receptor3 (FGFR3) gene and characterized by disproportionate short stature.Our main was to determine the efficacy of growth hormone therapy in children with HCH, compared with a historical cohort of 40 untreated children with HCH.Diagnosis of subjects was confirmed by the Bone Dysplasia Center2. Height standard dev...

Management of patients presenting a chronic endocrine or metabolic disease during transition period is a challenge for multiple reasons. The department of Adult Endocrinology and Reproductive Medicine in Pitie Salpêtrière Hospital, Paris has been involved in the management of such patients for many years. However, in our own experience, 81% of patients are still followed-up after 1 year, 71% after 3 years and only 49% after 5 years. Based on such experience, we decid...

Adrenal Dysfunction in HIV-Exposed Uninfected Infants Receiving Ritonavir-Boosted Lopinavir, an HIV Protease Inhibitor, for the Prevention of Breastfeeding HIV Transmission. An ANRS 12174 Substudy

Background: We recently demonstrated that both ritonavir-boosted lopinavir (LPV/r) and lamivudine (3TC, a nucleoside analogue) given to breastfed infants can reduce the risk of post natal HIV transmission (ANRS 12174 trial; Nagot, Lancet 2016). In another setting we previously showed the occurrence of adrenal dysfunction in newborn perinatally exposed to LPV/r leading to acute adrenal insufficiency in premature babies (Simon, JAMA 2011).Objective and hyp...

Background: Non-classical congenital adrenal hyperplasia (NCCAH) may present during childhood, adolescence or even adulthood with various degrees of hyperandrogenism. Diagnosis is established through tetracosactide (Synacthen®) test and genotyping. Cortisol insufficiency has rarely been described in NCCAH.Objective and hypotheses: To describe cortisol response to tetracosactide test in NCCAH patients.Method: Retrosp...
