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

5 months to 14 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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
Measure Description
Time Frame
Ht SDSca (Height Standard Deviation Score for Chronological Age)
Time Frame: Baseline
Ht SDSca was calculated by dividing the difference between the actual height of a patient and the mean height of the population for that chronological age by the standard deviation (SD) of the height of the population for that chronological age
Baseline
Change of yearly growth velocity from baseline to 26 weeks
Time Frame: Baseline, 26 weeks after initiating treatment
Height velocity calculate by formula
Baseline, 26 weeks after initiating treatment
Ht SDSca
Time Frame: 26 weeks after initiating treatment
Ht SDSca was calculated by dividing the difference between the actual height of a patient and the mean height of the population for that chronological age by the standard deviation (SD) of the height of the population for that chronological age
26 weeks after initiating treatment

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
Measure Description
Time Frame
Ht SDSBA (Height Standard Deviation Score for Bone Age)
Time Frame: Baseline,26 weeks after initiating treatment
Baseline,26 weeks after initiating treatment
IGF-1 SDS (IGF-1 Standard Deviation Score)
Time Frame: Baseline,26 weeks after initiating treatment
Baseline,26 weeks after initiating treatment
IGFBP-3 SDS (IGFBP-3 Standard Deviation Score)
Time Frame: Baseline,26 weeks after initiating treatment
Baseline,26 weeks after initiating treatment
Skeletal maturity
Time Frame: Baseline,26 weeks after initiating treatment
Skeletal maturity=(Bone Age at 26 weeks-Bone Age at baseline)/treatment duration
Baseline,26 weeks after initiating treatment

General Publications

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2015

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.
