Long-acting growth hormone in the treatment of growth hormone deficiency in children: a systematic literature review and network meta-analysis

Abstract

The purpose of this study is to compare the relative efficacy and safety of long-acting growth hormone (LAGH) as a growth hormone replacement therapy in prepubertal children with growth hormone deficiency (GHD). We searched the PubMed, Embase, CNKI, and Wanfang databases from inception to July 2023 and identified eleven relevant studies. PEG-LAGH showed better effect on height velocity (mean difference [MD]: − 0.031, 95% credibility interval [CrI]: − 0.278, 0.215) than somatrogon (MD: 0.105, 95% CrI: − 0.419, 0.636), somapacitan (MD: 0.802, 95% CrI: − 0.451, 2.068) and lonapegsomatropin (MD: 1.335, 95% CrI: − 0.3, 2.989) when compared with daily growth hormone (DGH). Furthermore, in terms of height standard deviation score, PEG-LAGH demonstrated better improvement (MD: − 0.15, 95% CrI: − 1.1, 0.66) than somatrogon (MD: − 0.055, 95% CrI: − 1.3, 0.51) and somapacitan (MD: 0.22, 95% CrI: − 0.91, 1.3). PEG-LAGH (risk ratio [RR]: 1.00, 95% CrI: 0.82, 1.2) reduced the risk of adverse events compared with other LAGH (somatrogon, RR: 1.1, 95% CrI: 0.98, 1.2; somapacitan, RR: 1.1, 95% CrI: 0.96, 1.4; lonapegsomatropin, RR, 1.1, 95% CrI: 0.91, 1.3) and was comparable with DGH. This is the first study to indirectly compare the LAGH thorough a network meta-analysis and provide evidence of the optimal efficacy of various LAGH specifically PEG-LAGH and acceptable safety profile in prepubertal children with GHD.
