  • Birth weight within the normal range;
  • Growth hormone treatment-naive;
  • Participants are willing and able to cooperate to complete scheduled visits, treatment plans and laboratory tests and other procedures, to sign informed consent.
Exclusion Criteria
  • Participants with abnormal liver and kidney functions (ALT > upper limit 1.5 times of normal value; Cr > upper limit of normal value);

  • Participants are positive for anti-HBc, HbsAg or HbeAg in Hepatitis B virus tests;

  • Participants with known highly allergic constitution or allergy to investigational product or its excipient;

  • Participants with systemic chronic disease and immune deficiency;

  • Participants diagnosed with tumor, or with potential high tumor risks such as tumor markers exceed normal range and some other relative information may be excluded from the treatment;

    1. Growth hormone deficiency (GHD) (confirmed by GH stimulation test);
    2. Turner syndrome (confirmed by karyotype test of girls);

rhGH/Jintropin AQNegative controlJintropin AQ, injection, 30IU/10mg/3ml/cartridge, 0.05mg /kg/d in phase 1 and 0.05-0.07mg/kg/d in phase 2.
Primary Outcome Measures
NameTimeMethod
ΔHtSDSca (The change of height standard deviation score of chronological age before and after treatment)Baseline, 4,13,26,39,52,65,78,91,104 weeks after initiating treatment, 52 weeks in phase 1; 2 years in phase 2.

ΔHtSDSca was the difference of HtSDSca before and after treatment, and HtSDSca was calculated by dividing the difference between the actual height of a patient and the mean height of the population for that chronological age by the standard deviation (SD) of the height of the population for that chronological age.

Secondary Outcome Measures
NameTimeMethod
Yearly growth velocityBaseline, 4,13,26,39,52,65,78,91,104 weeks after initiating treatment, 52 weeks in phase 1; 2 years in phase 2.
ΔIGF-1 SDS (Change of insulin-like growth factor 1 standard deviation score)Baseline, 4,13,26,39,52,65,78,91,104 weeks after initiating treatment, 52 weeks in phase 1; 2 years in phase 2.
ΔHT (Change of height)Baseline, 4,13,26,39,52,65,78,91,104 weeks after initiating treatment, 52 weeks in phase 1; 2 years in phase 2.
△BA/CA (bone age change / chronological age)Baseline, 4,13,26,39,52,65,78,91,104 weeks after initiating treatment, 52 weeks in phase 1; 2 years in phase 2.
