August 2, 2019 updated by: Ipsen

Predictive Value of Baseline and Stimulated Serum IGF-1 and IGFBP-3 During a Dose-escalation IGF-1 Generation Test for the 1 Year Growth Response to Growth Hormone (GH) Therapy in Short Children With Low IGF-1 and a Normal GH Peak in a Provocation Test

The evaluation of a standardized diagnostic test to predict the growth response in a 1 year trial with Growth Hormone (GH) treatment (carried out in the context of regular patient care) in non GH deficient short children with low serum insulin-like growth factor-1 (IGF-1).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

Ages Eligible for Study

2 years to 10 years (CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age 2.0 - 9.0 years for females, 2.0 - 10.0 yrs for males.
  • Prepubertal stage (Tanner 1 for breast (B1) in females, or Tanner 1 for genitals (G1) for males).
  • Bone age < 10 'years' (males) or < 9 'years' (females) according to Greulich and Pyle. The bone age will be read by the pediatric endocrinologist responsible for the pre-study screening visit.
  • Height SDS < -2.5 for ethnically adequate references. For children of Dutch or Western European origin the 1997 nation-wide references for Dutch children will be used. For children of Moroccan or Turkish origin, the respective reference charts will be used. For children of other ethnicities, the 1977 North American (NCHS/WHO) reference will be used, as these charts have been accepted by WHO as world-wide standard from the age of 5 years.

Exclusion Criteria:

  • Has a history of hypersensitivity to growth hormone or phenol (conservative added to GH in NutropinAq), or drugs with a similar chemical structure.
  • Has abnormal baseline findings, any other medical condition(s) or laboratory findings that, in the opinion of the Investigator, might jeopardise the subject's safety or decrease the chance of obtaining satisfactory data needed to achieve the objective(s) of the study.
  • Has a birth weight and/or length below -2 SDS for Swedish reference charts. Patients will not be excluded due to an unknown birth weight or length.
  • Has a known cause of short stature, or any significant concomitant disease that is likely to interfere with growth or with the study schedule/objectives, or is a known contraindication to GH treatment.

Design Details

  • Primary Purpose: DIAGNOSTIC
  • Allocation: NA
  • Interventional Model: SINGLE_GROUP
  • Masking: NONE

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: NutropinAq
Drug: Nutropin [Somatropin (rDNA origin) for injection]
Doses in the diagnostic protocol are 0.7 and 1.4 mg/m2/day, injected by subcutaneous injection at bedtime for 2 weeks, divided by washout periods of preferably 4 weeks (accepted range 4-6 weeks). An additional period of 2 weeks on 2.8 mg/m2/day (after a washout period of 4-6 weeks) will be added if the IGF-I response on either dosage is insufficient (serum IGF-I SDS <0).

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
Peak serum IGF-1 level with GH (1.4 mg/m2/day) change from baseline.
Time Frame: Week 2
Week 2

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
Delta IGF-1 SDS on 0.7 & 1.4 mg GH/m2/day

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
