A Study of Recombinant Human Growth Hormone Injection for Short Children With Small for Small for Gestational Age(SGA)

Phase Ⅲ Clinical Study of Recombinant Human Growth Hormone Injection (JINTOPIN AQ) for Short Children With Small for Gestational Age(SGA)

According to the results of the phase II study, choose the best dose of JINTOPIN AQ for short SGA children, further to evaluate the efficacy and safety of the treatment of short SGA children.

• Prepubertal stage (Tanner I).
• Height was lower than the mean -2SD of the values of normal children of the same age and gender when participating in the study.
• A GH peak concentration >10µg/L in a provocative test within a year before participating in the study.
• Bone age<Chronological age+1.
• Normal glucose regulation：Fasting blood-glucose < 5.6mmol/L, and 2 hours postprandial blood-glucose < 7.8mmol/L.
• Gestational age was 37 to 42 weeks.
• The subjects and their guardians signed informed consent.

Exclusion Criteria:

• Subjects with Liver and renal insufficiency (ALT > 1.5 times of upper limit of normal value, Cr> upper limit of normal value).
• Patients are positive for antibodies to hepatitis B core (HBc), hepatitis B surface antigen (HBsAg) or hepatitis B e antigen (HBeAg).
• Known Highly allergic constitution or allergic to the test drug.
• Subjects with diabetes, severe cardiopulmonary and pulmonary disease, and hematological diseases, malignant tumors, or systemic infection, immunocompromised patients and patients with psychosis.

• Subjects who have received the treatment of GH.
• Subjects took part in other clinical trial study within 3 months.
• Children who have treated with other hormone (such as gonadal hormone and glucocorticoids etc, continuous administration of more than a month) and that may affect growth hormone secretion or action including oxygen male dragon, growth hormone releasing hormone, etc. within 3 months.
• Other conditions which in the opinion of the investigator preclude enrollment into the study.
