Objective: Polyethylene glycol recombinant human growth hormone (PEG-rhGH, Jintrolong ® ) is the first long-acting rhGH preparation that is approved to treat children with growth hormone deficiency (GHD) in China. Clinical experience with dose selections of PEG-rhGH is scarce. The present study compared the efficacy and safety of a lower dose to increase dosing regimens of PEG-rhGH treatment. Methods: A multicenter, randomized, open-label, dose-comparison clinical study was conducted to compare the improvements in the height standard deviation score (Ht SDS), height velocity (HV), insulin-like growth factor-1 (IGF-1) SDS, and safety profiles of children with GHD who are treated with 0.2 mg/kg/week of PEG-rhGH dose or 0.14 mg/kg/week for 26 weeks. Results: Ht SDS, HV, and IGF-1 SDS increased significantly after PEG-rhGH treatment in the two dose groups ( p < 0.05). The improvements of Ht SDS, HV, and IGF-1 SDS were more significant in the high-dose group than in the low-dose group ( p < 0.05). Ht SDS improvement in low-dose group was not non-inferiority to that in the high-dose group ( p = 0.2987). The incidences of adverse events were comparable between the two groups. Conclusion: The improvements of Ht SDS, HV, and IGF-1 SDS were more significant in the high-dose group than in the low-dose group ( p < 0.05). PEG-rhGH at the dose of 0.14 mg/kg/week was effective and safe for children with GHD. Clinical Trial Registration: clinicaltrials.gov , identifier NCT02908958.
