A Novel Y-Shaped Pegylated Recombinant Human Growth Hormone for Children With Growth Hormone Deficiency

Resumo original em inglês

O que aconteceu

Pegpesen is a novel Y-shape pegylated recombinant human growth hormone (rhGH) for once-weekly treatment of children with growth hormone deficiency (GHD).

This work aimed to evaluate the efficacy and safety of Pegpesen in children with GHD vs daily rhGH.

A multicenter, randomized, controlled phase 3 clinical trial was conducted at 23 centers in China with a duration of 52 weeks' treatment. There were 391 pediatric participants diagnosed with GHD. Participants were randomly assigned 2:1 to a weekly Pegpesen group (140 μg/kg/week) or a daily rhGH group (245 μg/kg/week) for 52 weeks. The primary end point was the growth velocity (GV) at 52 weeks, and the secondary end points mainly involved changes from baseline in height SD scores for chronological age and bone age (ΔHt SDS CA and ΔHt SDS BA).

O que encontraram

At 52 weeks, the least squares mean (LS means) of GV was 9.910 cm/year in the Pegpesen group and 10.037 cm/year in the daily rhGH group. The LS means difference between groups was -0.127 (95% CI, -0.4868 to 0.2332), confirming that weekly Pegpesen is noninferior to daily rhGH. The LS means of ΔHt SDS CA, ΔHt SDS BA, were similar across both groups (all P > .05). Safety profiles and adherence were comparable.

Por que isso importa

Pegpesen was noninferior to daily rhGH, with similar safety, lower dosage requirements, thus presenting a new therapeutic option for children with GHD.
