Brief summary

IGF-1 (insulin-like growth factor-1) is a hormone that is normally produced in the body in response to another hormone called growth hormone. Growth Hormone is produced by a small gland at the base of the brain (the pituitary). Together IGF-1 and GH are large contributors to growth during infancy, childhood, and adolescence. Children with IGF Deficiency are short and have an imbalance in the levels of growth hormone and IGF-1 that their body produces. Their growth hormone levels are normal or even high, but IGF-1 levels do not increase normally in response to growth hormone. As a result, they have a type of growth hormone insensitivity and an inability to grow normally. This study is a test to see whether daily dosing with a combination of rhIGF-1 and rhGH will help children with IGFD grow taller more quickly than children treated with rhGH alone. The study medications, rhIGF-1 and rhGH, are approved by the US Food and Drug Administration (FDA) for use in some growth disorders in children, but the combination of rhIGF-1 and rhGH in children with IGF-1 deficiency (IGFD) is investigational.

MeasureTime frameDescription
Cumulative Change in Height Standard Deviation Score (SDS)First, second, third and fourth yearHeight was measured standing and without shoes, and recorded as the mean of three measurements (the subject being repositioned each time) by the same observer using a Harpenden or other wall-mounted stadiometer which was to be calibrated prior to measurement of each subject and a calibration log kept. The SDS was calculated as: SDS=\[(value /M)\^L - 1\] / LS; using power (L), Mean (M) and coefficient of variation (S). The reference values were dependent on gender in addition to age and were selected at the age the closest below subject's age. SDS scores were calculated using L, M and S as defined in the National Center for Health Statistics 2000 data as provided by the Center for Disease Control (Kuczmarski, Ogden et al. 2002)
Predicted Adult Height (PAH)At baseline (Day 1), year 1,2,3 and 4Predicted Adult Height calculated by method, Roche-Wainer-Thissen (RWT) and mid-parental target height SDS. The SDS was calculated as: SDS=\[(value /M)\^L - 1\] / LS; using power (L), Mean (M) and coefficient of variation (S). The reference values were dependent on gender in addition to age and were selected at the age the closest below subject's age. SDS scores were calculated using L, M and S as defined in the National Center for Health Statistics 2000 data as provided by the Center for Disease Control (Kuczmarski, Ogden et al. 2002)
Total Change From Baseline (Day 1) in BMI SDSAt year 1,2,3,4 and end of study (visit 23) versus baseline (day 1)BMI was calculated by weight divided by height squared and measured as kilogram per square meter (kg/m\^2). The SDS was calculated as: SDS=\[(value /M)\^L - 1\] / LS; using power (L), Mean (M) and coefficient of variation (S). The reference values were dependent on gender in addition to age and were selected at the age the closest below subject's age. SDS scores were calculated using L, M and S as defined in the National Center for Health Statistics 2000 data as provided by the Center for Disease Control (Kuczmarski, Ogden et al. 2002)
Skeletal MaturationAt baseline(day 1), year 1,2,3 and 4Assessed by bone age. Bone age was determined by the radiograph. The SDS was calculated as: SDS=\[(value /M)\^L - 1\] / LS; using power (L), Mean (M) and coefficient of variation (S). The reference values were dependent on gender in addition to age and were selected at the age the closest below subject's age.

Cumulative Change in Height Standard Deviation Score (SDS)

Height was measured standing and without shoes, and recorded as the mean of three measurements (the subject being repositioned each time) by the same observer using a Harpenden or other wall-mounted stadiometer which was to be calibrated prior to measurement of each subject and a calibration log kept. The SDS was calculated as: SDS=\[(value /M)\^L - 1\] / LS; using power (L), Mean (M) and coefficient of variation (S). The reference values were dependent on gender in addition to age and were selected at the age the closest below subject's age. SDS scores were calculated using L, M and S as defined in the National Center for Health Statistics 2000 data as provided by the Center for Disease Control (Kuczmarski, Ogden et al. 2002)

Time frame: First, second, third and fourth year

The SDS was calculated as: SDS=\[(value /M)\^L - 1\] / LS; using power (L), Mean (M) and coefficient of variation (S). The reference values were dependent on gender in addition to age and were selected at the age the closest below subject's age. SDS scores were calculated using L, M and S as defined in the National Center for Health Statistics 2000 data as provided by the Center for Disease Control (Kuczmarski, Ogden et al. 2002)

Skeletal Maturation

Assessed by bone age. Bone age was determined by the radiograph. The SDS was calculated as: SDS=\[(value /M)\^L - 1\] / LS; using power (L), Mean (M) and coefficient of variation (S). The reference values were dependent on gender in addition to age and were selected at the age the closest below subject's age. SDS scores were calculated using L, M and S as defined in the National Center for Health Statistics 2000 data as provided by the Center for Disease Control (Kuczmarski, Ogden et al. 2002)

Time frame: At baseline(day 1), year 1,2,3 and 4

Population: Completers, the completer population consists of all subjects that remained in the study until a specific time point (ie; Year 1, Year 2, Year 3 and Year 4).

Total Change From Baseline (Day 1) in BMI SDS

BMI was calculated by weight divided by height squared and measured as kilogram per square meter (kg/m\^2). The SDS was calculated as: SDS=\[(value /M)\^L - 1\] / LS; using power (L), Mean (M) and coefficient of variation (S). The reference values were dependent on gender in addition to age and were selected at the age the closest below subject's age. SDS scores were calculated using L, M and S as defined in the National Center for Health Statistics 2000 data as provided by the Center for Disease Control (Kuczmarski, Ogden et al. 2002)

Time frame: At year 1,2,3,4 and end of study (visit 23) versus baseline (day 1)

Population: Completers, the completer population consists of all subjects that remained in the study until a specific time point (ie; Year 1, Year 2, Year 3 and Year 4).
