Outcome Measures

Primary Outcomes (2)

  • Annualized Height Velocity Up to 12 Years

    Height velocity is the difference between 2 height measurements, divided by years elapsed between measurements.

    Baseline (Pre-dose) and up to 12 years

  • Number of Naive Participants With Height Velocity <5 cm/y at the End of 1 Year of Study Treatment

    Height measurements were performed using wall-mounted stadiometers for analysis of growth data.

    Baseline (Pre-dose) and 1 year

Secondary Outcomes (3)

  • Height Velocity Standard Deviation Score Up to 12 Years

    Baseline (Pre-dose) and up to 12 years

  • Height Standard Deviation Score Up to 12 Years

    Baseline (Pre-dose) and up to 12 years

  • Approximate Increase in Height Over Expected for Naïve Participants With Near-Adult Height

    Baseline (Pre-dose) and up to 19 years

Study Arms (1)

mecasermin, injections BID of rhIGF-1

EXPERIMENTAL
Drug: mecasermin

Interventions
