Brief Summary
This is a multicenter, randomized, open-labeled, positive controlled phase 2\&3 combined study to evaluate the safety and efficacy of weekly Y-shape pegylated somatropin, compared to daily somatropin ...
Detailed Description
This multicenter, randomized, open-labeled, positive controlled study is divided into two stages. The first one is aimed to exploit the optimal dose of Y-shape pegylated somatropin, while the second o...
Eligibility Criteria
Inclusion
- Diagnosis of GHD confirmed by two different GH stimulation tests, defined as a peak of GH level of \<10.0 ng/ml, determined with a validated assay. Bone age (BA) at least 2 years less than the chronological age. Growth velocity less than 5.0 cm/year. Impaired HT defined as at least 2.0 standard deviations (SD) below of the mean height for chronological age and sex (HT SDS\<-2.0).
- Prepubertal (Tanner Ⅰ) males and females by physical examination, aged older than 3 years and younger than10 years for girls and 11 years for boys.
- Short stature with normal intelligence.
- Baseline IGF-1 level below the median IGF-1 level standardized for age and sex.

Exclusion

- Known hypersensitivity to somatropin or excipients, such as mannitol, lysine, sodium chloride.
- Children with closed epiphyses.
- Short stature etiologies other than GHD, such as idiopathic short stature, Turner syndrome, Prader-Willi syndrome, Russell-Silver syndrome, born small for gestational age regardless of GH status.
- Other causes of short stature such as hypothyroidism, adrenocortical hormone deficiency, antidiuretic hormone deficiency.
- Any medical conditions and/or presence that may affect growth velocity such as liver dysfunction, kidney dysfunction, malnutrition, diabetes mellitus, severe dysfunction in major organ such as heart, sever systemic infections, severe immune dysfunction, mental disorders, and other congenital malformations.
- Suffering from chronic infectious diseases such as chronic hepatitis B, AIDS or tuberculosis.

- Evidence of congenital intracranial hypertension.
- Evidence of slipped capital femoral epiphysis.
- Evidence of scoliosis over 15°.
- Participation in any other trial of an investigational agent within 3 months prior to screening.
- Any other conditions which in the opinion of the investigator precluded enrollment into the study.
