In addition, short stature often results in life-long emotional, social, and physical obstacles to the affected person.\n\nNormal 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).\n\nSome 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.\n\nLHRHa (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.", "DetailedDescription"=>"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.\n\nWe 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."}, "EligibilityModule"=>{"Gender"=>"All", "StdAgeList"=>{"StdAge"=>["Child", "Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"Patients with extreme short stature will qualify for inclusion under this protocol if they meet the following criteria:\n\nAge 9 through 15.99 years at the start of treatment.\n\nTanner II-V pubertal development.\n\nHeight 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.\n\nThe 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.\n\nUnfused carpal and phalangeal epiphyses by bone age x-ray."}, "IdentificationModule"=>{"NCTId"=>"NCT00001190", "BriefTitle"=>"Study of Luteinizing Hormone-Releasing Hormone Analog (LHRHa) in Pubertal Patients With Extreme Short Stature", "Organization"=>{"OrgClass"=>"NIH", "OrgFullName"=>"National Institutes of Health Clinical Center (CC)"}, "OfficialTitle"=>"A Double-Blind, Randomized, Placebo-Controlled Clinical Trial of Luteinizing Hormone-Releasing Hormone Analog (LHRHa) in Pubertal Patients With Extreme Short Stature", "OrgStudyIdInfo"=>{"OrgStudyId"=>"830199"}, "SecondaryIdInfoList"=>{"SecondaryIdInfo"=>[{"SecondaryId"=>"83-CH-0199"}]}}, "ArmsInterventionsModule"=>{"InterventionList"=>{"Intervention"=>[{"InterventionName"=>"Deslorelin", "InterventionType"=>"Drug"}]}}, "ContactsLocationsModule"=>{"LocationList"=>{"Location"=>[{"LocationZip"=>"20892", "LocationCity"=>"Bethesda", "LocationState"=>"Maryland", "LocationCountry"=>"United States", "LocationFacility"=>"National Institute of Child Health and Human Development (NICHD)"}]}}, "SponsorCollaboratorsModule"=>{"LeadSponsor"=>{"LeadSponsorName"=>"Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)", "LeadSponsorClass"=>"NIH"}}}}}}
