Étude sur l'efficacité et l'innocuité du lonapegsomatropine hebdomadaire comparé à la somatropine quotidienne chez les enfants et adolescents présentant une petite taille ou un retard de croissance dû à des troubles avec production suffisante d'hormone de croissance
Une étude pivot, à bras parallèles, de phase 3, ouverte, contrôlée active, mondiale, multicentrique, en panier randomisée évaluant l'efficacité et l'innocuité du lonapégsomatropine hebdomadaire comparé à la somatropine quotidienne chez les enfants prépubères et les adolescents présentant un retard de croissance ou une petite taille dus à des troubles avec suffisance en hormone de croissance - syndrome de Turner, déficit en SHOX, petit pour l'âge gestationnel et petite taille idiopathique
This basket trial will enroll prepubertal children and adolescents with clinically diagnosed and genetically confirmed (if applicable) TS, SHOX-D, SGA, or ISS between ages of ≥2 and <18 years with open growth plates. The purpose of the study is to see how well treatment with once-weekly lonapegsomatropin works compared to treatment with daily somatropin. Approximately 186 participants will be distributed equally (1:1), to receive either lonapegsomatropin for 2 years or somatropin for 1 year followed by lonapegsomatropin for 1 year. This trial will be conducted in the United States, France, Germany, Italy, Romania, Spain and South Korea.

Exclusion Criteria only applicable to SGA:
a. Any known clinically significant abnormality likely to affect growth or the ability to evaluate growth with standing height measurements: (i.)Chromosomal aneuploidy, significant gene mutations, or medical syndromes with short stature, including but not limited to Turner syndrome, Laron syndrome, Noonan syndrome, Prader-Willi syndrome, abnormal SHOX-1 gene analysis or absence of GH receptors.
