  Purpose
This trial is conducted in Europe. The aim of this trial is to assess whether increasing doses of somatropin (Norditropin®) can maintain the initial increase in height velocity and improve final height. This trial has two trial periods, a main period of 4 years and an extension period until final height is reached.

  • Adverse events

Enrollment: 65
Study Start Date: November 1989
Study Completion Date: September 2003
Primary Completion Date: September 2003 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Low dose Drug: somatropin
4 IU/m^2 body surface for 4 years (main period). In extension period subjects continue the reached dose until final height. Administered as once daily subcutaneous injection
Drug: oestrogen
Treatment with oestrogen was administered if spontaneous puberty had not occurred by age 12 years and was initiated in the extension period after at least four years of somatropin treatment
Experimental: Medium dose Drug: somatropin
Initial dose 4 IU/m^2 body surface the first year, then 6 IU/m^2 body surface for 3 years (main period). In extension period subjects continue the reached dose until final height. Administered as once daily subcutaneous injection
Drug: oestrogen
Treatment with oestrogen was administered if spontaneous puberty had not occurred by age 12 years and was initiated in the extension period after at least four years of somatropin treatment
Experimental: High dose Drug: somatropin
Initial dose 4 IU/m^2 body surface the first year, then 6 IU/m^2 body surface, the second year and finally 8 IU/m^2 body surface for 2 years (main period). In extension period subjects continue the reached dose until final height. Administered as once daily subcutaneous injection
Drug: oestrogen
Treatment with oestrogen was administered if spontaneous puberty had not occurred by age 12 years and was initiated in the extension period after at least four years of somatropin treatment
