Study of Luteinizing Hormone-Releasing Hormone Analog (LHRHa) in Pubertal Patients With Extreme Short Stature
A Phase 2 study testing Deslorelin in people with Dwarfism and Growth Disorder, run by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) at 1 site in United States.
Trial summary
Children with extreme short stature (height) and their families often experience significant psychological stress related to concerns about adult height. In addition, short stature often results in life-long emotional, social, and physical obstacles to the affected person. Normal growth occurs in two phases. Read more about this study

Patients with extreme short stature will qualify for inclusion under this protocol if they meet the following criteria:
Age 9 through 15.99 years at the start of treatment.
Tanner II-V pubertal development.
Height at least 2.25 S.D. below the median for chronologic age at the time of pubertal onset, or a predicted adult height at least 2.25 S.D. below median adult height.
The height criterion must be met before study entry, but not necessarily on the actual date the patient starts to take the protocol injections because advancing puberty may cause an increase in height velocity that temporarily increases height standard deviation score.
Unfused carpal and phalangeal epiphyses by bone age x-ray.

About this study
Official title: A Double-Blind, Randomized, Placebo-Controlled Clinical Trial of Luteinizing Hormone-Releasing Hormone Analog (LHRHa) in Pubertal Patients With Extreme Short Stature
Children with extreme short stature (height) and their families often experience significant psychological stress related to concerns about adult height. In addition, short stature often results in life-long emotional, social, and physical obstacles to the affected person.
Normal growth occurs in two phases. The first phase, known as childhood growth, occurs below the age of 10. The second phase of growth, teen-age or adolescent growth, begins between the ages of 10 and 15. In addition, puberty marks the time when the bone's growth plates (epiphysis) begin to close, initiating the completion of linear growth (height).

Some children suffer from a condition called precocious puberty, meaning that puberty begins at a younger age than normal. The development of medications known as synthetic LHRH analogs have provided a method to delay puberty and treat these patients.
LHRHa (deslorelin) is a hormone created to act like naturally occurring LHRH. It been used in patient's diagnosed with precocious (early onset) puberty. The drugs were able to regress patient's clinical signs of puberty, decrease the levels of adult sex hormones produced, and slow the rate of bone aging.
Read the detailed description
Children with extreme short stature and their families frequently experience significant psychological stress related to concerns about adult height. Additionally, extreme short stature often presents life-long emotional, social, and physical obstacles to the affected individual. The onset of puberty in such patients presents a critical management problem because puberty initiates the process of epiphyseal closure that terminates linear growth. Until recently, there was no way to delay the onset of puberty in such patients. The development of synthetic LHRH analogs, however, has provided such a method. Administration of such analogs to children with precocious puberty caused a regression of their clinical signs of puberty, a decrease in their gonadotropins and sex steroids, and a slowing of the rate of bone age advancement.
We propose to treat pubertal children with extreme short stature with a long-acting analog of luteinizing hormone-releasing hormone (D-Trp6-Pro9-NEt-LHRHa). The goal of LHRHa treatment in these children is to halt the normal progression into puberty and thereby delay epiphyseal fusion. We postulate that delay of puberty will prolong pre-pubertal growth prior to the pubertal spurt and subsequent epiphyseal fusion, and thus will enhance ultimate height. This study will test this hypothesis through a double-blind, randomized comparison of the effect of LHRHa and placebo on final adult height. Patients will be treated with LHRHa or placebo for 4 years, and will then be followed until they have completed puberty and have stopped growing.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00001190, which also lists 3 linked publications.
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 Mar 2008.
