A Study of the Effects of Pegvisomant on Growth Hormone Excess in McCune-Albright Syndrome
NCT00017927 · View on ClinicalTrials.gov ↗
Study Summary
This study will examine the effect of pegvisomant on growth hormone excess in patients with McCune-Albright syndrome (MAS). Patients with this disease have polyostotic fibrous dysplasia-a condition in which areas of normal bone are replaced with fibrous growth similar to scar tissue, abnormal skin pigmentation (birth marks) and precocious (early) puberty. About 10 percent of patients have excess growth hormone (GH). GH stimulates the production of another hormone called insulin-like growth factor 1 (IGF-1). Together, GH and IGF-1 affect bone growth. The excess of these hormones in MAS can cause overgrowth of the bones of the face, hands and feet, excess sweating, or increased height. Pegvisomant is a synthetic drug that binds to cell receptors where GH would normally bind, thus preventing the naturally occurring hormone from stimulating IGF-1 and bone growth as it normally would. This study will see if pegvisomant will reduce blood levels of IGF-1 and mitigate the effects of growth hormone excess, including bone pain, bone turnover, hand and foot swelling and sweating, and abnormal levels of related hormones. Patients who were screened for polyostotic fibrous dysplasia and MAS under NIH protocol 98-D-0145 and were found to have MAS with excess growth hormone are eligible for this 36-week study. The screening protocol includes a history and physical examination, blood and urine tests, hearing, eye and dental examinations, pain and physical function evaluations, endocrine and bone screening tests, various bone imaging studies, including magnetic resonance imaging (MRI) and computed tomography (CT) scans and bone biopsy in patients over 6 years old. Participants in the current study will receive daily injections of either pegvisomant or placebo (an inactive substance) for 12 weeks, followed by a 6-week "washout" period with no drug. Then, patients who received placebo will be switched, or "crossed over," to receive pegvisomant for another 12 weeks, and those who rec

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00017927
The ClinicalTrials.gov registry entry for NCT00017927 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 10 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Dental and Craniofacial Research (NIDCR), which has 60 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with McCune Albright Syndrome appearing as the primary indexed condition, and to 1 intervention — of which Pegvisomant 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: NCT00017927 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.
