Biochemical Markers of Growth Response to Growth Hormone Treatment in Children With Idiopathic Short Stature (ISS)

January 1, 2013 updated by: Rabin Medical Center

One Arm, Open Study to Assess Biochemical Markers of Growth Response to Growth Hormone Treatment in Children With Idiopathic Short Stature

One arm, open, prospective, intervention study to assess biochemical markers of growth response to Growth Hormone treatment in 20 Children, aged 3-9 years old, with idiopathic short stature. All participants will be treated with Growth Hormone during the first year of the study (and then in accordance with the local ethic requirement, to supply drug which is not approved for the indication used in the study, for additional 3 years) and then will be followed up for the next 3 years. The impact of Growth Hormone therapy on clinical laboratory parameters that are indicative of the growth response will be assessed by collecting blood and urine samples during the 4 years study period. The primary endpoints are measurements of height and growth velocity during the year of Growth Hormone treatment, the height at the beginning of puberty and final height. Secondary endpoints are psychological parameters, assessed by questionnaires.

Detailed Description

One arm, open prospective intervention study to assess biochemical markers of growth response to Growth Hormone treatment in 20 children, aged 3-9 years old, with idiopathic short stature.

Objectives:

  1. To determine axiological and biochemical markers for growth response
  2. To assess the period of time necessary to determine the parameters which will differentiate between responders and non-responders

Inclusion criteria:

  1. Ages 3 to <9 years
  2. Short stature with height >2.25 Standard Deviation below the mean
  3. Prepubertal (Tanner stage I) at commencement of trial
  4. Peak Growth Hormone above 10ng/ml in at least one provocative test for Growth Hormone secretion
  5. Signing Informed consent forms

Exclusion criteria:

  1. Intra Uterine Growth Retardation
  2. Growth retardation associated with malignancy, severe chronic disease, genetic syndromes and endocrine disorders
  3. Diabetes
  4. Treatment with any medical product which may interfere with Growth Hormone effects

Methods:

  1. All participants will be treated with Growth Hormone during the first year of the study (and then in accordance with the local ethic requirement, to supply drug which is not approved for the indication used in the study, for additional 3 years) and then will be followed up for the next 3 years.
  2. The impact of Growth Hormone therapy on clinical laboratory parameters that are indicative of the growth response will be assessed by collecting blood and urine samples during the 4 years study period.Samples will be test for biochemical markers of bone formation and resorption
  3. The primary endpoints are measurements of height and growth velocity during the year of Growth Hormone treatment, the height at the beginning of puberty and final height. Secondary endpoints are psychological parameters, assessed by questionnaires.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame

Time Frame: every 4 months
every 4 months
Growth velocity
Time Frame: every 4 months

Height at beginning of puberty

Final height
Time Frame: When acheiving final height
When acheiving final height

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time Frame: once a year
