Quality of life in children and adolescents with growth hormone deficiency and their caregivers: an Italian survey. J Endocrinol Invest 2023; 46:2513-2523. [PMID: 37209402 PMCID: PMC10632207 DOI: 10.1007/s40618-023-02106-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Accepted: 04/30/2023] [Indexed: 05/22/2023]
Abstract
PURPOSE The aim of this study was to produce evidence on quality of life (QoL) among Italian growth hormone deficiency (GHD) children and adolescents treated with growth hormone (GH) and their parents. METHODS A survey was conducted among Italian children and adolescents aged 4-18 with a confirmed diagnosis of GHD and treated with GH therapy and their parents. The European Quality of Life 5 Dimensions 3 Level Version (EQ-5D-3L) and the Quality of Life in Short Stature Youth (QoLISSY) questionnaires were administered between May and October 2021 through the Computer-Assisted Personal Interview (CAPI) method. Results were compared with national and international reference values. RESULTS The survey included 142 GHD children/adolescents and their parents. The mean EQ-5D-3L score was 0.95 [standard deviation (SD) 0.09], while the mean visual analogue scale (VAS) score was 86.2 (SD 14.2); the scores are similar to those of a reference Italian population aged 18-24 of healthy subjects. As for the QoLISSY child-version, compared to the international reference values for GHD/ idiopathic short stature (ISS) patients, we found a significantly higher score for the physical domain, and lower scores for coping and treatment; compared to the specific reference values for GHD patients, our mean scores were significantly lower for all domains except the physical one. As for the parents, we found a significantly higher score for the physical domain, and a lower score for treatment; compared to reference values GHD-specific, we found lower score in the social, emotional, treatment, parental effects, and total score domains. CONCLUSIONS Our results suggest that the generic health-related quality of life (HRQoL) in treated GHD patients is high, comparable to that of healthy people. The QoL elicited by a disease specific questionnaire is also good, and comparable with that of international reference values of GHD/ISS patients.

Efficacy and Safety of Weekly Somatrogon vs Daily Somatropin in Children With Growth Hormone Deficiency: A Phase 3 Study. J Clin Endocrinol Metab 2022; 107:e2717-e2728.

Abstract
CONTEXT Somatrogon is a long-acting recombinant human growth hormone (rhGH) in development for once-weekly treatment of children with growth hormone deficiency (GHD). OBJECTIVE We aimed to compare the efficacy and safety of once-weekly somatrogon with once-daily somatropin in prepubertal children with GHD. METHODS In this 12-month, open-label, randomized, active-controlled, parallel-group, phase 3 study, participants were randomized 1:1 to receive once-weekly somatrogon (0.66 mg/kg/week) or once-daily somatropin (0.24 mg/kg/week) for 12 months. A total of 228 prepubertal children (boys aged 3-11 years, girls aged 3-10 years) with GHD, impaired height and height velocity (HV), and no prior rhGH treatment were randomized and 224 received ≥1 dose of study treatment (somatrogon: 109; somatropin: 115). The primary endpoint was annualized HV at month 12. RESULTS HV at month 12 was 10.10 cm/year for somatrogon-treated subjects and 9.78 cm/year for somatropin-treated subjects, with a treatment difference (somatrogon-somatropin) of 0.33 (95% CI: -0.24, 0.89). The lower bound of the 2-sided 95% CI was higher than the prespecified noninferiority margin (-1.8 cm/year), demonstrating noninferiority of once-weekly somatrogon vs daily somatropin. HV at month 6 and change in height standard deviation score at months 6 and 12 were similar between both treatment groups. Both treatments were well tolerated, with a similar percentage of subjects experiencing mild to moderate treatment-emergent adverse events in both groups (somatrogon: 78.9%, somatropin: 79.1%). CONCLUSION The efficacy of once-weekly somatrogon was noninferior to once-daily somatropin, with similar safety and tolerability profiles. (ClinicalTrials.gov no. NCT02968004).

Abstract
The widespread availability of recombinant human growth hormone (GH) since 1985 has made it possible to extend growth hormone therapy indications for children with different etiologies of short stature. It is now accepted that GH is effective in increasing height velocity in children with GH deficiency (GHD) and well tolerated in both the short and long terms. Nevertheless, one major factor in the inter-individual variability of the growth response to GH in GHD children is adherence to daily injections. In an attempt to improve patient adherence, there has been a strong effort from industry to create a long-acting form of growth hormone to ease the burden of its use. It is theorized that by decreasing injection frequency, Long-Acting GH (LAGH) would improve adherence and therefore outcomes. These agents can be divided broadly into depot formulations, PEGylated formulations, prodrug formulations, noncovalent albumin-binding GH and GH fusion proteins. In 2021, two LAGH formulations are on the market in China and South Korea, and several promising agents are under clinical investigation at various stages of development throughout the world. A number of safety issues related to LAGH have been identified and need to be further investigated. © 2022 French Society of Pediatrics. Published by Elsevier Masson SAS. All rights reserved.

Abstract
Somatrogon (NGENLA®), a long-acting human growth hormone based on C-terminal peptide technology, is in development by Pfizer and OPKO Health for the treatment of growth hormone deficiency in pediatric and adult patients. Administered as a once-weekly subcutaneous injection, somatrogon reduces treatment burden relative to once-daily human growth hormone therapy while providing non-inferior efficacy. Somatrogon received its first approval in October 2021 in Canada for the long-term treatment of pediatric patients who have growth failure due to an inadequate secretion of endogenous growth hormone (growth hormone deficiency). This article summarizes the milestones in the development of somatrogon leading to this first approval for the treatment of growth hormone deficiency.
