Comparative Outcomes of GH Treatment in Pediatric Idiopathic Short Stature and GH Deficiency. (PubMed, J Endocr Soc) - "This post hoc analysis of the NordiNet International Outcome Study (2006-2016) and the American Norditropin Studies: Web-Enabled Research Program (2002-2016) included children with ISS or GHD who initiated treatment aged <18 years...Incidence of adverse reactions was similar across indications, with no new safety signals. GH treatment over 5 to 10 years effectively increased height in children with ISS and children with GHD, including those who reached NAH, with a favorable benefit-risk profile."

Circulating IGF-1 Levels and Trends in Response to Daily and Weekly GH Therapies: A Comparative Analysis (ESPE-ESE 2025) - " Data were synthesized from eight studies analyzing IGF-1 response to various GH therapies, including daily rGH and weekly long-acting formulations such as somapacitan, PEG-rhGH, TransCon GH, and Nutropin Depot...Daily GH Therapies: Daily rGH therapy (e.g., Genotropin, Norditropin) resulted in more consistent IGF-1 levels with minor daily fluctuations, providing a steady profile throughout the week-(Lundberg et al., 2018)... Both weekly and daily GH therapies effectively elevate IGF-1 levels, with distinct advantages and limitations. Weekly formulations optimize patient adherence and long-term exposure, whereas daily rGH ensures consistent IGF-1 profiles.

Growth hormone therapy demonstrates no clinical impact on thyroid function in children with growth hormone deficiency (ESPE-ESE 2025) - "Methods Three randomized, multinational, open-labeled parallel-group phase 2 (REAL3, n=59) and phase 3 (REAL4, n=200; and REAL6, n=110) trials investigated efficacy and safety of once-weekly somapacitan compared to once-daily GH (Norditropin®, Novo Nordisk) administration in treatment-naïve, prepubertal children with GHD. Clinicians can be reassured that GH therapy does not pose a significant risk of inducing hypothyroidism. Cases with central GHD warrants special attention."

Evaluation of features for a digital application for growth hormone therapy using perceptions gathered from patients, caregivers and healthcare professionals (ESPE-ESE 2025) - "Insights from patients, caregivers and healthcare professionals (HCPs) were gathered to inform the development of MySoConnect® for Sogroya® (Novo Nordisk Health Care AG)...Patients were current users of the Norditropin® (somatropin) FlexPro® pen (Novo Nordisk Health Care AG)...HCPs were strongly in favour of adding an automated dose-logging feature, which corresponds to a connectivity element between the injection pen and the app, to encourage app use. Insights gathered from patients, caregivers and HCPs indicate that the use of an app for GHT may support adherence to treatment, with features such as tracking height gain over time, setting reminders and accessing instructional manuals and other relevant supporting information considered beneficial."

Efficacy and safety of somapacitan versus daily growth hormone at 52 weeks in patients with growth hormone deficiency: pooled analysis of the randomised REAL 3, REAL 4 and REAL 6 clinical trials (ESPE-ESE 2025) - P2, P3 | "We present outcomes from a pooled analysis of data from three clinical trials (REAL 3 [NCT02616562], REAL 4 [NCT03811535] and REAL 6 [NCT04970654]) assessing the efficacy and safety of somapacitan versus daily GH (Norditropin®, Novo Nordisk). Outcomes from a pooled analysis of REAL 3, REAL 4 and REAL 6 demonstrate similar efficacy of somapacitan compared to daily GH over 52 weeks of treatment, with comparable safety and mean IGF-I SDS change in treatment-naïve children with GHD."

Pharmacodynamic Endpoints After Once-Weekly Somapacitan in Children With GHD: 3-year results from REAL4 phase 3 study (ESPE 2024) - P3 | "The trial randomised (2:1) 200 GH-treatment-naïve, prepubertal children with GHD to once-weekly somapacitan (0.16 mg/kg; n=132) or once-daily GH (Norditropin® 0.034 mg/kg; n=68) for 52 weeks. IGF-I SDS >2.0 at two consecutive visits occurred in 2 (1.7%) and 1 (1.7%), respectively, with no observed trend in the amount or type of AEs. In conclusion, after three years of somapacitan and two years of somapacitan following switch from daily GH, IGF-I SDS, IGFBP-3 SDS, and IGF-I/IGFBP-3 molar ratio were similar between groups, and mean IGF-I SDS and IGFBP-3 SDS were within normal range."
