Primary Outcome Measures:
  • Height gain at 2 year [ Time Frame: At least after 2 years of treatment (initial interventional study), then it was agreed to follow-up patients until end of treatment (non-interventional FU) and if feasible to collect final height ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Tolerability criteria (Clinical): general and local tolerability (collection of AEs/SAEs) [ Time Frame: Within first 2 years of treatment (initial interventional study), then it was agreed to follow-up patients until end of treatment (non-interventional FU) and to collect potential SAEs until end of treatment ] [ Designated as safety issue: Yes ]
  • Tolerability criteria (Metabolic): HBA1c [ Time Frame: Every 6 month within first 2 years of treatment (initial interventional study), then it was agreed to follow-up patients until end of treatment (non-interventional FU) ] [ Designated as safety issue: No ]
  • Tolerability criteria (Radiologic): Bone age [ Time Frame: Every 6 month within first 2 years of treatment (initial interventional study), then it was agreed to follow-up patients until end of treatment (non-interventional FU) ] [ Designated as safety issue: No ]
  • Tolerability criteria (Immunologic): Anti-GH and anti non-hGH proteins antibodies [ Time Frame: Systematically at 3, 6, 12 and 24 months and at 9, 12, 18 and 36 months if positive result(s) at 6 month then it was agreed to follow-up patients until end of treatment (non-interventional FU) ] [ Designated as safety issue: No ]
  • Tolerability criteria: IGF1 [ Time Frame: Within first 2 years of treatment (initial interventional study), then it was agreed to follow-up patients until end of treatment (non-interventional FU) ] [ Designated as safety issue: No ]
  • Efficacy criteria: Height and weight evolution [ Time Frame: Within first 2 years of treatment (initial interventional study), then it was agreed to follow-up patients until end of treatment (non-interventional FU) ] [ Designated as safety issue: No ]

Primary Completion Date: March 1999 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Group Q
Subjects with height <-2SD / standard height (sempé cohort) received 0.15 IU/kg/day
Other: 0.15 IU/kg/day GH
Group Q = 0.15 IU/kg/day (was interventional at the time of protocol writing)
Group U
Subjects with height <-1 SD and >-2SD / standard height (sempé cohort) received 0.1 IU/kg/day
Other: 0.1 IU/kg/day GH
Group U = 0.1 IU/kg/day (was interventional at the time of protocol writing)

Detailed Description:

The study started as an interventional clinical trial. Following primary completion of the trial, the sponsor together with the investigators decided that it was interesting to perform an observational follow up of the patients, who participated in the interventional part of the study, in order to retrieve more outcome results and safety information on this cohort of young turner patients for whom treatment started before the age of 4. The follow up period was then to be performed until end of GH treatment as decided by the treating physician according to usual clinical practice. More recently, it was agreed to also collect information on final adult height and weight for patients not lost to follow up.
