Abstract
Abstract
Background
Growth hormone deficiency (GHD) is a condition impacting children and adults, leading to low height and other health issues. The primary treatment is daily injections of recombinant human growth hormone (rhGH), though they can be inconvenient and costly. These injections may also negatively impact treatment adherence and outcomes. This study aims to compare the efficacy and safety of once-weekly growth hormone treatment vs daily growth hormone therapy in children with growth hormone insufficiency.
Methods
To examine the efficacy and safety of once-weekly and once-daily growth hormone treatment for children with growth hormone insufficiency, this meta-analysis followed PRISMA and Cochrane standards. RCTs and prospective cohort studies with children aged 0–18 diagnosed with GHD were considered eligible. We used the risk of bias 2 and the certainty of evidence using the Cochrane tools. Two authors independently assessed papers for eligibility and extracted data after conducting a thorough search of electronic resources. Height velocity, height standard deviation score, insulin-like growth factor 1 levels, and the incidence of adverse events were the primary outcomes. The Revman software version 5.4 was used for data synthesis, and heterogeneity was determined by I-squares greater than 60%.
Results
This meta-analysis and comprehensive review includes 14 randomized clinical trials and one study was cohort, including 1,322 children with growth hormone insufficiency. Weekly growth hormone treatment at dosages ranging from 0.11 to 0.25 mg enhanced a variety of growth outcomes, including increased height velocity dose (SMD = 0.37, 95% CI, 0.23–0.51; P < 0.001), height standard deviation scores chronological age (SMD= -0.10, 95% CI, -0.13–0.07; P < 0.001), and insulin-like growth factor 1 standard deviation score (SMD = 0.41, 95% CI, 0.40–0.42; P < 0.001). The dosage range of 0.26 to 0.50 mg also improved insulin-like growth factor binding protein-3 significantly (SMD= -0.63, 95% CI, -0.90 – -0.37; P < 0.001). Nevertheless, there were no significant differences in the occurrence of adverse events through the dosage levels (OR = 0.71, 95% CI 0.36 to 1.40; P = 0.32).
Conclusions
In children with growth hormone deficit, weekly growth hormone treatment, particularly in the 0.11 to 0.25 mg dose range, can function as a viable alternative to daily growth hormone therapy.

Efficacy, safety, quality of life, adherence and cost-effectiveness of long-acting growth hormone replacement therapy compared to daily growth hormone in children with growth hormone deficiency: a systematic review and meta-analysis. Pharmacol Res 2023:106805. [PMID: 37236413 DOI: 10.1016/j.phrs.2023.106805] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 05/09/2023] [Accepted: 05/23/2023] [Indexed: 05/28/2023]
Abstract
We evaluated the efficacy, safety, adherence, quality of life (QoL) and cost-effectiveness of long-acting growth hormone (LAGH) vs daily growth hormone (GH) preparations in the treatment of growth hormone deficiency (GHD) in children. Systematic searches were performed in PubMed, Embase and Web of Science up to July 2022 on randomized and non-randomized studies involving children with GHD receiving LAGH as compared to daily GH. Meta-analyses for efficacy and safety were performed comparing different LAGH/daily GH formulations. From the initial 1,393 records, we included 16 studies for efficacy and safety, 8 studies for adherence and 2 studies for QoL. No studies reporting cost-effectiveness were found. Pooled mean differences of mean annualized height velocity (cm/year) showed no difference between LAGH and daily GH: Eutropin Plus® vs Eutropin® [-0.14 (-0.43, 0.15)], Eutropin Plus® vs Genotropin® [-0.74 (-1.83, 0.34)], Jintrolong® vs Jintropin AQ® [0.05 (-0.54, 0.65)], Somatrogon vs Genotropin® [-1.40 (-2.91, 0.10)], TransCon vs Genotropin® [0.93 (0.26, 1.61)]. Also, other efficacy and safety outcomes, QoL and adherence were comparable for LAGH and daily GH. Our results showed that, although most of the included studies had some concerns for risk of bias, regarding efficacy and safety all the LAGH formulations were similar to daily GH. Future high quality studies are needed to confirm these data. Adherence and QoL should be addressed from real-world data studies for both the mid and long term and in a larger population. Cost-effectiveness studies are needed to measure the economic impact of LAGH from the healthcare payer's perspective.

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
Background We performed a meta-analysis to evaluate the efficacy and safety of weekly long-acting growth hormone replacement therapy compared to daily growth hormone in children with short stature. Methods A systematic literature search up to April 2021 was performed and 11 studies included 1,232 children with short stature treated with growth hormone replacement therapy at the start of the study; 737 of them were using weekly long-acting growth hormone replacement therapy and 495 were using daily growth hormone. They were reporting relationships between the efficacy and safety of long-acting growth hormone replacement therapy and daily growth hormone in children with short stature. We calculated the odds ratio (OR), and mean difference (MD) with 95% confidence intervals (CIs) to assess the efficacy and safety of weekly long-acting growth hormone replacement therapy compared to daily growth hormone in children with short stature using the dichotomous or continuous method with a random or fixed-effect model. Results Long-acting growth hormone replacement therapy had significantly lower height standard deviation scores chronological age (MD, -0.10; 95% CI, -0.13 to -0.08, p <0.001), and insulin-like growth factor binding protein-3 (MD, -0.69; 95% CI, -1.09 to -0.30, p <0.001) compared to daily growth hormone in children with short stature.However, growth hormone replacement therapy had no significantly difference in height velocity (MD, -0.09; 95% CI, -0.69-0.5, p = 0.76), height standard deviation scores bone age (MD, -0.04; 95% CI, -0.10-0.02, p = 0.16), insulin-like growth factor 1 standard deviation scores (MD, 0.26; 95% CI, -0.26-0.79, p = 0.33), and incidence of adverse events (OR, 1.16; 95% CI, 0.90-1.50, p = 0.25) compared to daily growth hormone in children with short stature. Conclusions Long-acting growth hormone replacement therapy had significantly lower height standard deviation scores chronological age, and insulin-like growth factor binding protein-3 compared to daily growth hormone in children with short stature. However, growth hormone replacement therapy had no significant difference in height velocity, height standard deviation scores bone age, insulin-like growth factor 1 standard deviation scores, and incidence of adverse events compared to daily growth hormone in children with short stature. Further studies are required to validate these findings.

Abstract
Introduction: There have been significant clinical advances in the understanding of the diagnosis and benefits of long-term recombinant human growth hormone (rhGH) replacement in adults with GH deficiency (GHD) since its approval in 1996 by the United States Food and Drug Administration.Areas covered: We searched PubMed, Medline, CINAHL, EMBASE and PsychInfo databases between January 2000 and June 2019 for published studies evaluating adults with GHD. We reviewed the data of the oral macimorelin test compared to the GHRH plus arginine and the insulin tolerance tests that led to its approval by the United States FDA and European Medicines Agency for adult diagnostic testing. We summarize the clinical advances of long-term benefits of rhGH therapy and the potential effects of GH receptor polymorphisms on individual treatment responsiveness. We identify that non-adherence and discontinuation rates are high and recommend strategies to support patients to improve adherence. We also provide an overview of several long-acting GH (LAGH) preparations currently under development and their potential role in improving treatment adherence.Expert opinion: This article summarizes recent clinical advances in rhGH replacement therapy, the biological and molecular aspects that may influence rhGH action, and offers practical strategies to enhance adherence in adults with GHD.

Abstract
PURPOSE Long-acting growth hormone (GH) has been developed to address the noncompliance and decreased efficacy associated with daily GH injections. We aimed to evaluate the efficacy and safety of long-acting GH replacement therapy in children with short stature. METHODS Randomized controlled trials (RCTs) that investigated the efficacy and safety of long-acting GH therapy in children with short stature in comparison with daily GH injections were searched in Medline, Embase, and the Cochrane Central Register of Controlled Trials. A random-effect model was used to pool data using mean difference and odds ratios (OR). (PROSPERO registration number: CRD42018111105). RESULTS Seven relevant studies were finally included. Meta-analysis found there was no significant difference between high-dose long-acting GH and daily GH in terms of height velocity (HV) (mean difference (MD) = -0.10, 95% CI, -0.79 to 0.60, P = 0.79). Moreover, no significant difference was observed in height standard deviation scores (Ht SDS) between high-dose long-acting GH and daily GH (MD = -0.07, 95% CI, -0.18 to 0.03, P = 0.17). Treatment with high-dose long-acting GH significantly increased IGF-1 SDS when compared with daily GH (MD = 0.31, 95% CI, 0.06-0.56, P = 0.02). In safety assessment, no significant difference was observed in the incidence of adverse events between high-dose long-acting GH and daily GH (OR 1.42, 95% CI, 0.65-3.11, P = 0.38). CONCLUSIONS There is no evidence to support differences in the effects of long-acting GH compared with those of daily GH. More RCTs that focus on the safety of high-dose long-acting GH treatment, especially the detection of adverse events caused by elevated levels of serum IGF-1, are needed in the future.

Abstract
Human growth hormone (hGH), which had been in use since 1958, was supplanted by recombinant human growth hormone (rhGH) in 1985 for those with growth hormone deficiency (GHD). Adherence to daily subcutaneous growth hormone is challenging for patients. Thus, several companies have pursued the creation of long acting rhGH. These agents can be divided broadly into depot formulations, PEGylated formulations, pro-drug formulations, non-covalent albumin binding GH and GH fusion proteins. Nutropin Depot is the only long acting rhGH ever approved by the U.S. Food and Drug Administration, and it was removed from the market in 2004. Of the approximately seventeen candidate drugs, only a handful remain under active clinical investigation or are commercially available.

Abstract
In this chapter, we want to give an overview on what we have learned from more than 30 years ago on the use of recombinant human growth hormone (rhGH) and later recombinant human IGF-1 which was introduced for the treatment of short children and what are the safety issues concerned with this treatment. However, rhGH is used not solely in conditions where short stature is the consequence of GH deficiency but also in various disorders without a proven GH deficiency. In clinical studies, growth responses to various forms of rhGH therapy were analyzed, adding to our concept about the physiology of growth. Most patients under rhGH treatment show a considerable short-term effect; however, the long-term gain of height in a child obtained by a year-long treatment until final height remains controversial in some of the growth disorders that have been treated with rhGH or IGF-1. Today the first studies on the long-term safety of rhGH treatment have been published and raising some questions whether this treatment is similarly safe for all the patient groups treated with rhGH. Although there is a long-standing safety record for these hormone replacement therapies, in the face of the considerable costs involved, the discussion about the risk to benefit ratio is continuing. Newer developments of rhGH treatment include long-term preparations, which have only to be injected once a week. Although some of these drugs already have proven their non-inferiority to conventional rhGH treatment, we have to await further results to see whether they show improvements in treatment adherence of the patients and prove their long-term safety.

Abstract
BACKGROUND/AIMS To determine the optimal dose of LB03002, a sustained-release, once-weekly formulation of recombinant human growth hormone (rhGH), and to compare its efficacy and safety with daily rhGH in children with idiopathic short stature (ISS). METHODS This multicenter, randomized, open-label, phase II study included GH-naïve, prepubertal children with ISS, randomized to receive daily rhGH 0.37 mg/kg/week (control, n = 16), LB03002 0.5 mg/kg/week (n = 14), or LB03002 0.7 mg/kg/week (n = 16). The primary endpoint was height velocity (HV) change at week 26. RESULTS At week 26, the least square (LS) means for HV change (cm/year) with control, LB03002 0.5 mg/kg/week, and LB03002 0.7 mg/kg/week were 5.08, 3.65, and 4.38, and the LS means for the change in height standard deviation score were 0.65, 0.49, and 0.58, respectively. The lower bound of the 90% confidence interval for the difference between LB03002 0.7 mg/kg/week and the control in the LS mean for HV change (-1.72) satisfied the noninferiority margin (-1.75). Adverse events were generally mild and short-lived. CONCLUSION A once-weekly regimen of LB03002 0.7 mg/kg demonstrated noninferiority to the daily regimen of rhGH 0.37 mg/kg/week in terms of HV increments. LB03002 was well tolerated and its safety profile was comparable with that of daily rhGH.

PURPOSE OF REVIEW To discuss the rationale of developing long-acting growth hormone (LAGH) preparations, to describe the technologies designed to prolong GH action, and to address key issues regarding efficacy, safety, and monitoring while on treatment. REVIEW FINDINGS Recombinant human GH is currently approved for daily use and has been shown to restore longitudinal growth, and improve body composition with relatively few side-effects in children and adults with GH deficiency, respectively. However, daily injections can be inconvenient, painful and distressing for some patients, resulting in decreased adherence and efficacy. Over a dozen pharmaceutical companies have designed LAGH preparations that are at various stages of development using a number of different methods to prolong GH action. SUMMARY LAGH will represent an advancement over daily recombinant human GH injections because of fewer injections that may offer increased acceptance, tolerability, and therapeutic flexibility to patients that potentially can improve treatment outcomes. However, given the unphysiological profile of LAGH preparations, long-term surveillance of efficacy and safety are needed. This review summarizes recent developments of LAGH preparations, and highlights the importance of long-term surveillance registries to assess for efficacy and safety that will be essential for understanding the impact of prolonged exposure to these compounds.

Abstract
Growth hormone (GH) and IGF-I levels in serum are used as biomarkers in the diagnosis and management of GH-related disorders but have not been subject to structured validation. Auxological parameters in children and changes in body composition in adults, as well as metabolic parameters and patient related outcomes are used as clinical and surrogate endpoints. New treatment options, such as long acting GH and GH antagonists, require reevaluation of the currently used biochemical biomarkers. This article will review biomarkers, surrogate endpoints and clinical endpoints related to GH treatment in children and adults as well as in acromegaly.

Design of the long-term observational cohort study with recombinant human growth hormone in Korean children: LG Growth Study. Ann Pediatr Endocrinol Metab 2018; 23:43-50. [PMID: 29609449 PMCID: PMC5894560 DOI: 10.6065/apem.2018.23.1.43] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2017] [Revised: 12/24/2017] [Accepted: 12/29/2017] [Indexed: 01/25/2023] Open
Abstract
PURPOSE Regarding recombinant human growth hormone (rhGH) use in the pediatric population, no long-term follow-up data are available for Korean patients. To fill in the gap of knowledge, a registry study (LG Growth Study) was initiated to assess the safety and effectiveness of four types of rhGH products in real-life settings. METHODS A total of 4,000 children will be registered and prospectively followed up at 6-month intervals until 2 years after epiphyseal closure to collect data on treatment and adverse events, with primary interest in malignancies and growth outcomes. RESULTS As of 22 March 2017, approximately 50% (2,024) of the target number of patients have been included in the analysis set: growth hormone deficiency, 1,297 (64.1%); idiopathic short stature, 315 (15.6%); small for gestational age, 206 (10.2%); Turner syndrome, 197 (9.7%); and chronic renal failure, 9 (0.4%). At baseline, median age (years) was 8 (interquartile range [IQR], 5-11); 52% (1,048) were boys; and the majority were at Tanner stage I (83% based on breast/external genitalia, 97% on pubic hair). Median height standard deviation score was -2.26 (IQR, -2.69 to -2.0), and median bone age delay (years) was -1.46 (IQR, -2.26 to -0.78). CONCLUSIONS This registry study will provide the opportunity to assess the risk of malignancies as well as the general safety data in Korean pediatric patients receiving rhGH. In addition, the long-term effectiveness of rhGH and comparative data between different disease entities will provide practical insight on the standard rhGH treatment.

Increased proportion of mature oocytes with sustained-release growth hormone treatment in poor responders: a prospective randomized controlled study. Arch Gynecol Obstet 2017; 297:791-796. [PMID: 29264647 DOI: 10.1007/s00404-017-4613-4] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2017] [Accepted: 09/19/2017] [Indexed: 10/18/2022]
Abstract
PURPOSE Supplementation of growth hormone (GH) during controlled ovarian stimulation (COS) has been suggested to improve ovarian response. Despite potential benefits in poor responders, multiple injections of GH during COS are inconvenient. We conducted a randomized controlled study to evaluate the efficacy and safety of sustained-release human GH in poor responders undergoing in vitro fertilization (IVF). METHODS This was a single-center, randomized, open-label, parallel study. Infertile women who satisfied the Bologna criteria for poor responders were randomized into GH treatment and control groups. The treatment group received a sustained-release GH (Eutropin Plus® 20 mg) three times before and during COS (mid-luteal, late luteal, and menstrual cycle day 2). The baseline characteristics and IVF outcomes were compared between the two groups. RESULTS A total of 127 patients were included in the analysis. The mean age was 39.6 years and mean anti-Müllerian hormone level was 0.6 ng/ml. There was no significant difference in the baseline characteristics between GH treatment and control groups. The number of follicles on the human chorionic gonadotropin triggering day (3.1 ± 2.3 vs. 2.4 ± 1.6, P = 0.043) and the proportion of metaphase II oocytes (67.5 vs. 52.3%, P = 0.030) were higher in the GH group than in controls. The percentage of clinical and ongoing pregnancy and miscarriage was not different between the two groups. CONCLUSION Supplementation of sustained-release GH before and during COS improved ovarian response, with an increase in mature oocytes in poor responders. Further studies are needed to ensure this benefit in general infertility patients.

Long-acting PEGylated recombinant human growth hormone (Jintrolong) for children with growth hormone deficiency: phase II and phase III multicenter, randomized studies. Eur J Endocrinol 2017; 177:195-205. [PMID: 28566441 PMCID: PMC5488390 DOI: 10.1530/eje-16-0905] [Citation(s) in RCA: 52] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2016] [Revised: 05/23/2017] [Accepted: 05/30/2017] [Indexed: 12/30/2022]
Abstract
OBJECTIVE We assessed the efficacy and safety of a weekly pegylated human growth hormone (PEG-rhGH) (Jintrolong) vs daily rhGH for children with growth hormone deficiency (GHD). DESIGN Phase II and III, multicenter, open-label, randomized controlled trials. METHODS 108 and 343 children with treatment-naive GHD from 6 hospitals in China were enrolled in the phase II and III studies respectively. Patients in the phase II study were randomized 1:1:1 to weekly Jintrolong (0.1 mg/kg/week PEG-rhGH complex), weekly Jintrolong (0.2 mg/kg/week PEG-rhGH complex) or daily rhGH (0.25 mg/kg/week) for 25 weeks. Patients in the phase III study were randomized in a 2:1 ratio to weekly Jintrolong (0.2 mg/kg/week) or daily rhGH (0.25 mg/kg/week) for 25 weeks. The primary endpoint for both studies was height velocity (HV) increase at the end of treatment. Other growth-related parameters, safety and compliance were also monitored. RESULTS The phase II study established the preliminary efficacy, safety and recommended dose of Jintrolong PEG-rhGH. In the phase III study, we demonstrated significantly greater HV increases in patients receiving Jintrolong treatment (from 2.26 ± 0.87 cm/year to 13.41 ± 3.72 cm/year) vs daily rhGH (from 2.25 ± 0.82 cm/year to 12.55 ± 2.99 cm/year) at the end of treatment (P < 0.05). Additionally, significantly greater improvement in the height standard deviation scores was associated with Jintrolong throughout the treatment (P < 0.05). Adverse event rates and treatment compliance were comparable between the two groups. CONCLUSION Jintrolong PEG-rhGH at a dose of 0.2 mg/kg/week for 25 weeks is effective and safe for GHD treatment and is non-inferior to daily rhGH.
