Saizen®Drug
Also called somatropin

| Study group | Role | What they receive |
|---|---|---|
| Saizen® 0.057 mg/kg/day | Experimental | Subjects who met all inclusion/exclusion criteria were randomly assigned to 0.057 mg/kg/day in this multi-center study. Subjects were stratified at randomization according to the Height-Standard Deviation Score (H-SDS) at this time (less than [<] -2 SDS or greater than [>] -2 SDS) Receives: Drug: Saizen® |
| Saizen® 0.035 mg/kg/day | Experimental | Subjects who met all inclusion/exclusion criteria were randomly assigned to 0.035 mg/kg/day in this multi-center study. Subjects were stratified at randomization according to the H-SDS at this time (< -2 SDS or > -2 SDS) Receives: Drug: Saizen® |
What is being measured
The primary outcome is the main question the study is designed to answer.
Height Velocity
Height Velocity (HV) is the change in height since the previous year´s measurement and more precisely: HV = {(h-hp)/(d-dp)} * 365.25 [centimeter (cm)/year] where h is current height in cm, hp is previous height in cm, closest to 1 year previous, d is the current date and dp is the date of measurement of previous height, closest to 1 year previous. Additionally, d and dp have to be within 0.6 years and 1.5 years. HV is the mean height velocity over the interval between d and dp but is displayed as HV at d.
Measured: Month 12
Secondary outcomes (7)
Change From Baseline in Height-Standard Deviation Score (H-SDS) at Month 6 and Month 12
Height-Standard Deviation Score (H-SDS) was calculated as height minus mean (age-and sex-matched reference) divided by standard deviation (SD) [age and sex-matched reference]. Greater H-SDS indicates greater height.
Measured: Baseline (randomization), Month 6 and Month 12
Height Velocity-Standard Deviation Score (HV-SDS)
Height Velocity-Standard Deviation Score (HV-SDS) was calculated as height velocity minus reference mean height velocity divided by SD of the reference mean height velocity. Greater HV-SDS indicates greater height velocity.
Measured: Month 6 and Month 12
Change From Baseline in Height at Month 6
Measured: Baseline (randomization) and Month 6
Change From Baseline in Bone Age at Month 12
Bone age was assessed by a left wrist X-Ray and evaluated by the investigator according to the Greulich and Pyle method.
Measured: Baseline (randomization) and Month 12
Insulin Like Growth Factor-1 (IGF-1) Levels
Measured: Baseline (randomization), Month 6 and Month 12
Insulin Like Growth Factor Binding Protein-3 (IGFBP-3) Levels
Measured: Baseline (randomization), Month 6 and Month 12
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
Adverse Events (AEs): Any untoward medical occurrence in the form of signs, clinically significant abnormalities in laboratory findings, diseases, symptoms, or worsening of complications. TEAEs: AEs that occur during treatment with the Investigational Medicinal Product (IMP).
Measured: Baseline (randomization) until Month 12

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Saizen® in people with Small Gestational Age (SGA), run by Merck KGaA, Darmstadt, Germany.
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 6 inclusion and 13 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 26 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.
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 10 Oct 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?
Height Velocity (time frame: Month 12). 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 NCT00249821, 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 26 Sep 2017.
