What is being measured
The primary outcome is the main question the study is designed to answer.
Ht SDSca (Height standard deviation score for chronological age)
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
Measured: Baseline, every 13 weeks until 130 weeks
Secondary outcomes (5)
Ht SDSBA (Height standard deviation score for bone age)
Measured: Baseline, every 13 weeks until 130 weeks
Yearly growth velocity
Measured: Baseline, every 13 weeks until 130 weeks
IGF-1 SDS (Standard deviation score of insulin-like growth factor-1)
Measured: Baseline, every 13 weeks until 130 weeks
Bone age
Measured: Baseline, 26 weeks, 52 weeks, 78 weeks, 104 weeks, 130 weeks
Near final height for some subjects
When yearly growth velocity of some subject is no more than 2cm/year.
Measured: Baseline, every 13 weeks until 130 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing PEG-somatropin in people with Growth Retardation, run by Changchun GeneScience Pharmaceutical Co., Ltd. at 1 site in China.
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 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record lists 1 site in China. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
Ht SDSca (Height standard deviation score for chronological age) (time frame: Baseline, every 13 weeks until 130 weeks). 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 NCT03290235, 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?
