Background and objective: Children with chronic kidney disease (CKD) have impaired growth that leads to short stature in adulthood and treatment with recombinant human growth hormone (rhGH) is associated with improved growth. This study aimed to evaluate the efficacy and safety of daily rhGH (Jintropin®) in children in China with growth failure caused by CKD prior to transplantation.
Methods: Prepubertal patients (213 years old) with CKD-related short stature were enrolled in this multicenter, randomized, open-label, negative-controlled study (NCT03535415). Eligible patients were randomized 1:1 to receive daily rhGH 0.05 mg/kg/day administered subcutaneously or control (no rhGH given, only relevant examinations were performed) for up to 52 weeks. The primary endpoint was improvement in (Δ) height standard deviation score (HT SDS). Secondary endpoints included improvements in height velocity (HV), bone maturation (bone age [BA]/chronological age [CA]), insulin-like growth factor 1 standard deviation score (IGF-1 SDS), IGF-1/IGF binding protein-3 (IGFBP-3) molar ratio, and safety.
Results: A total of 68 patients were randomized to either treatment or control; 11 patients (treatment: 7; control: 4) dropped out, 8 (treatment: 5; control: 3) of whom due to transplantation. At week 52, ΔHT SDS from baseline was 0.747±0.579 (P<0.001) and 0.173±0.470 (P=0.039) in the treatment and control groups, respectively (intergroup P<0.001). Least-squares mean difference between both groups was 0.582 (95% confidence interval 0.3230.842). Statistically significant improvements were also observed in those who received treatment compared with those in the control group for ΔHV (7.021±3.795 cm/year vs 2.566±3.577 cm/year; intergroup P<0.001), ΔIGF-1 SDS (1.697±2.098 vs 0.171±1.506; intergroup P<0.001), ΔIGF-1/IGFBP-3 molar ratio (0.046±0.073 vs 0.001±0.041; intergroup P<0.001), and Δheight (9.87±2.89 cm vs 6.43±2.72 cm; intergroup P<0.001). Δ(BA/CA) was 0.041±0.074 and 0.008±0.079 in the treatment and control groups, respectively (intergroup P=0.118). Most treatment-emergent adverse events (TEAEs) were mild to moderate; 19 patients (treatment: 10; control: 9) experienced serious adverse events, and 5 in the treatment group temporarily discontinued rhGH due to TEAEs. 7 reported drug-related TEAEs, which included elevated blood insulin, scoliosis, glycosuria, musculoskeletal discomfort, hyperinsulinemia, and abnormal liver function.
Conclusion: Daily rhGH 0.05 mg/kg per day for 52 weeks was effective and well tolerated in children with short stature caused by CKD. At the end of the study, significant improvements in ΔHT SDS, ΔHV, ΔIGF-1 SDS, ΔIGF-1/IGFBP-3 molar ratio, and Δheight were observed with treatment.
