  5. Pediatric patients whose epiphyses are closed with a growth rate of ≤1 cm/year at screening
  6. Pediatric patients who are being administered any drug that may have an effect on the secretion and actions of hGH (estrogen, androgen, anabolic steroids, corticosteroids, GnRH analogs, thyroxine, aromatase inhibitors, etc.) or anticonvulsants and cyclosporin at screening, and have been administered any of them for a long period of time within 6 months prior to screening (However, those who have been administered a thyroxine preparation for ≥4 weeks on a stable dose [allowable in case the investigator determines the dose is stable even though it is changeable based upon the weight of the pediatric patient] were allowed to participate in the clinical study.)
