What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Height Standard Deviation Score According to Chronological Age (SDS/CA) at Year 3
Height was measured using a wall mounted device (example, Harpenden stadiometer). Height SDS/CA was obtained by measuring the height, subtracting chronological age- and gender-appropriate mean height and dividing the result by standard deviation of that mean (as obtained from chronological age- and gender-specific population reference data). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) participant's value was relative to the mean of the reference population.
Measured: Baseline, Year 3
Change From Baseline in Height Standard Deviation Score According to Chronological Age (SDS/CA) at Final Height
Height was measured using a wall mounted device (example, Harpenden stadiometer). Height SDS/CA was obtained by measuring the height, subtracting chronological age- and gender-appropriate mean height and dividing the result by standard deviation of that mean (as obtained from chronological age- and gender-specific population reference data). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) participant's value was relative to the mean of the reference population.
Measured: Baseline, when final height was reached (assessed up to Year 11)
Change From Baseline in Weight Standard Deviation Score (SDS) at Final Height
Body weight was measured using a balance scale. Weight SDS was obtained by measuring the weight, subtracting age- and gender-appropriate mean weight and dividing the result by standard deviation of that mean (as obtained from age- and gender-specific population reference data). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) participant's value was relative to the mean of the reference population.
Measured: Baseline, when final height was reached (assessed up to Year 11)
Puberty Stage at Final Height
Pubertal stage (graded from I to V for breast development and pubic hair development) according to the Tanner's method was collected. A low stage (Stage I) corresponds to a pre-pubertal stage and a high stage (Stage V) to an adult stage.
Measured: When final height was reached (assessed up to Year 11)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Somatropin in people with Endocrine System Diseases, run by Pfizer at 2 sites in France.
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 2 inclusion and 2 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: stopped early, as of the sponsor's last update on 4 Dec 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in France. 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 4 Dec 2012). 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?
Change From Baseline in Height Standard Deviation Score According to Chronological Age (SDS/CA) at Year 3 (time frame: Baseline, Year 3). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00174187, which also lists 1 linked publication.
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 4 Dec 2012.
