This is an extension study to Tercica study MS301 (NCT00125164) and is intended to collect long term safety and efficacy data on the continued use of recombinant human insulin-like growth factor-1 (rh IGF-1) in children and adolescents treated for primary IGF-1 deficiency (IGFD). The secondary objective is to use the data collected to learn more about the relationship of IGF-1 exposure to the promotion of normal growth and pubertal development.

Primary Outcome Measures:
  • Height Velocity in Modified Intent-to-Treat Population (ITT Patients Randomized to 120 Mcg/kg Twice Daily) [ Time Frame: after one year of treatment ]
    Height to be measured standing without shoes as the average of three measurements by the same observer using identical technique with a Harpenden or other wall mounted stadiometer. Reposition subject between each measurement.

Secondary Outcome Measures:
  • Height Velocities During Subsequent Years of rh IGF-1 Treatment [ Time Frame: after 2, 3 and 5 years of treatment ]
    Height to be measured standing without shoes as the average of three measurements by the same observer using identical technique with a Harpenden or other wall mounted stadiometer. Reposition subject between each measurement.

  • Height Velocity Standard Deviation (SD) Score [ Time Frame: during the course of the study ]
  • Height SD Score [ Time Frame: during the course of the study ]

Enrollment: 114
Study Start Date: November 2005
Study Completion Date: March 2010
Primary Completion Date: February 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: rh IGF-1 (mecasermin)
    Patients from untreated arm for prior study MS301 (NCT00125164) were randomized to a dose of either 80 or 120 mcg/kg twice daily. For patients receiving active treatment in previous study MS 301 (NCT00125164), they started on a dose of 80 or 120 mcg/kg twice daily based on the dose reached at end of the previous study. Following a protocol amendment in May 2009, all patients were switched to once daily doses of 160 µg/kg, escalated to a targeted maximum dose of 240 µg/kg.
    Other Name: Increlex
Detailed Description:

Primary IGFD is a term that has been used to describe patients with intrinsic cellular defects in GH action. In this protocol, subjects that have completed one year of mecasermin treatment on Tercica protocol MS301 (NCT00125164) will be allowed to enroll in this extension study. All subjects were planned to receive treatment.

This is a Phase IIIb open-label, multi-center, parallel dose, extension study conducted in approximately 40 centers across the United States.
