About this study

Official title: Recombinant Human Insulin-Like Growth Factor (rhIGF-1) Treatment of Prepubertal Children With Growth Failure Associated With Primary IGF-1 Deficiency: A Phase 3, Randomized, Open Label, Observation-Controlled, Multicenter, Parallel-Dose Comparison Trial

This study is intended to determine whether twice daily weight based dosing with recombinant human insulin-like growth factor (rhIGF-1) will safely and effectively increase the growth of prepubertal children with short stature associated with low IGF-1 levels but who produce sufficient growth hormone (GH). Subjects will be randomized to either an observation arm or to active treatment.

Read the detailed description

Prepubertal growth failure associated with primary IGF-1 deficiency (IGFD). Primary IGFD is a term that has been used to describe patients with intrinsic cellular defects in GH action. In this protocol, primary IGFD is defined as short stature (height standard deviation score[SDS]<-2 below the mean for age and gender), low serum IGF-1 (IGF-1 SDS <-2 below the mean for age and gender), and levels of growth hormone (GH) that are normal (≥7ng/mL) after a GH stimulation test. Primary IGFD is believed to result from a lower than normal ability to produce IGF-1 when exposed to normal levels of GH, i.e., a type of GH insensitivity or GH resistance.

This trial is one year, randomized, open label, observation-controlled, parallel-dose comparison efficacy and safety study conducted in approximately 40 centers across the United States.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Height Velocity During the First Year - Intent to Treat (ITT)Population

    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.

    Measured: Measured at baseline and at one year

Secondary outcomes (8)
  1. Change From Baseline in Height Standard Deviation (SD) Score at One Year - ITT Population

    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. Please note that Standard Deviation (SD) Score is a term used in growth studies. The SD Score is calculated as the patient value minus the mean divided by the standard deviation. The mean and the standard deviation vary depending on the age and sex of the child.

    Measured: Measured at baseline and at one year

  2. Changes in Bone Age From Baseline to One Year

    Plain X-rays of the left hand and wrist exposed for bone age appraisal. The films are sent to a central facility for standardized evaluation.

    Measured: Measured at baseline and at one year

  3. Percent Changes From Baseline in Serum Concentrations of IGF-1 at One Year

    Blood sample was collected while subject is in a fasting state for measuring the level of IGF-1 in the growth factor panel.

    Measured: Measured at baseline and at one year

  4. Percent Changes From Baseline in Serum Concentrations of IGF-2 at One Year

    Blood sample was collected for measuring the level of IGF-2 in the growth factor panel.

    Measured: Measured at baseline and at one year

  5. Percent Changes From Baseline in Serum Concentrations of Insulin-like Growth Factor Binding Protein-2 (IGFBP-2) at One Year

    Blood sample was collected for measuring the level of insulin-like growth factor binding protein-2 (IGFBP-2) in the growth factor panel.

    Measured: Measured at baseline and at one year

  6. Percent Changes From Baseline in Serum Concentrations of Insulin-like Growth Factor Binding Protein-3 (IGFBP-3) at One Year

    Blood sample was collected while subject is in a fasting state for measuring the level of IGFBP-3 in the growth factor panel.

    Measured: Measured at baseline and at one year

  7. IGF Generation Test: Change of Serum IGF-1 After 7 Days Exposure to Recombinant Human Growth Hormone (rhGH)

    Blood drawn at Study Day 1, followed by 7 days of rhGH daily dosing at 0.05 mg/kg of body weight. Additional blood draw at Study Day 7.

    Measured: Study Day 1 and Day 7

  8. IGF Generation Test: Change of Serum IGFBP-3 After 7 Days Exposure to Recombinant Human Growth Hormone (rhGH)

    Blood drawn at Study Day 1, followed by 7 days of rhGH daily dosing at 0.05 mg/kg of body weight. Additional blood draw at Study Day 7.

    Measured: Study Day 1 and Day 7

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing rhIGF-1 (mecasermin, Tercica, Inc.) in people with Growth Disorders and Insulin-Like Growth Factor-1 Deficiency, run by Ipsen at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 30 Apr 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Height Velocity During the First Year - Intent to Treat (ITT)Population (time frame: Measured at baseline and at one year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2019.
