Albright Hereditary Osteodystrophy: Natural History, Growth, and Cognitive/Behavioral Assessments
NCT00209235 · View on ClinicalTrials.gov ↗
Study Summary
We, the researchers, are following the natural history of Albright hereditary osteodystrophy. We have found that growth hormone deficiency is very common in patients with pseudohypoparathyroidism type 1A, which falls under the broader condition termed Albright hereditary osteodystrophy. Patients with pseudohypoparathyroidism type 1A typically are short and obese. Some of these patients are not short during childhood, but due to a combination of factors, they end up short as adults. We are evaluating the effect of growth hormone treatment in those patients with pseudohypoparathyroidism type 1A who are found to be growth hormone deficient (under R01 FD002568, IND 67148, which ended); those who are growth hormone sufficient and were found to have a positive clinical response to growth hormone in a prior clinical trial (under R01 FD00FD003409, IND 67148, which ended); or those who meet the criteria of idiopathic short stature or SGA. We are also evaluating neurocognitive and psychosocial functioning in participants with AHO in order to determine the specific impairments that are most common in the condition and to determine the best approach toward management.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00209235
The ClinicalTrials.gov registry entry for NCT00209235 describes a study currently listed as recruiting. It is categorized as NA, 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 600 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Connecticut Children's Medical Center, which has 84 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Albright Hereditary Osteodystrophy appearing as the primary indexed condition, and to 1 intervention — of which Neurocognitive and psychosocial testing 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: NCT00209235 reports 1 study location spanning 1 distinct geographic area — top geographies include Connecticut. 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. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
