Official title
Pharmacodynamics of C-Type Natriuretic Peptide During Growth Hormone Treatment in Children: A Potential Biomarker of Efficacy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
It is now widespread practice to treat children with short stature with growth hormone. However, how an individual child will respond to growth hormone treatment is unpredictable and highly variable. Some children will not respond to growth hormone treatment at all. Currently, the only way to determine how well growth hormone therapy is working is to wait until they have been treated for six months and to compare the pre-treatment growth velocity with the growth velocity on treatment. It would be helpful to have a blood test that could be done shortly after starting growth hormone that could predict whether how well a child is responding to treatment. Such a blood test would allow endocrinologists to adjust the growth hormone dose (or possibly stop it altogether, if it is not working) long before the six months it currently takes. C-type natriuretic peptide (CNP) and its partner amino-terminal propeptide of CNP (NTproCNP) are proteins that play a critical role in regulating growth. The investigators have previously shown that blood levels of these proteins increase in children being treated with growth hormone. The investigators believe that a blood test for these proteins will be useful in predicting a child's response to growth hormone treatment. The purpose of this study is to determine when after starting growth hormone, the blood levels of CNP and NTproCNP start to increase.
