Growth Hormone Therapy in Osteogenesis Imperfecta
NCT00001305 · View on ClinicalTrials.gov ↗
Study Summary
Growth deficiency is a key feature of severe Osteogenesis Imperfecta (OI) and a frequent feature of mild to moderate forms of the disease. The reason that children with OI are short is not fully understood. We do know that details such as the number of fractures suffered or the type of OI do not fully explain the short stature of OI. Growth patterns have been defined for children with OI Types I, III, and IV. At about 12 months of age, children with Types III and IV OI demonstrate a predictable plateau of their linear growth rate. Type IV OI children begin to resume a normal growth rate at about age four to five years, but they will not "catch up" to a normal height, as they have "lost" a significant period of growth. The plateau usually continues for children with Type III OI. The reason for this growth plateau is unknown. There have been no studies which evaluate the growth of OI children in this age range. Our previous studies of growth in OI children have begun at age 5 years. We have studied growth in OI children for the past 10 years. Different medications have been tried to both stimulate growth and improve bone density. Some children have responded to growth hormone (their growth rate increased by at least 50%) and some did not. The majority of children who did respond were Type IV. However, we need to carefully treat and study more children to try to determine which children will benefit from growth hormone medication. The Goals of this Study Are: 1. We want to try to find a cause for the growth plateau common in types III and IV OI. Long-term, our goal is to develop a treatment to eliminate this plateau. 2. We want to see how long and how well OI bone will respond to growth stimulation. 3. We hope to find a "predictor" for who will respond to growth hormone and who will not, by measuring your child's endocrine and growth hormone function before receiving any growth hormone treatment. 4. We want to measure the effects of growth stimulation on bone densit

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00001305
The ClinicalTrials.gov registry entry for NCT00001305 describes a study currently listed as completed. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 42 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), which has 237 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Osteogenesis Imperfecta appearing as the primary indexed condition, and to 1 intervention — of which Humatrope is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00001305 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
