Effects of Growth Hormone Administration on Cardiovascular Risk in Cured Acromegalics With Growth Hormone Deficiency
NCT00182091 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of the study is to evaluate the effects of growth hormone (GH) replacement in men and women with a history of acromegaly and who are now growth hormone deficient. We will compare them to persons with a history of acromegaly who have normal GH levels. Acromegaly results when an area in the brain, called the pituitary, produces too much growth hormone. When an individual is cured of acromegaly, the growth hormone levels may be normal or low (that is GH deficiency). Growth hormone deficiency means the body no longer produces as much growth hormone because the pituitary/hypothalamic region was damaged by a tumor or by treatment received. We will study the effects of growth hormone replacement on the health of the heart and blood vessels of GH deficient persons by looking to see if this therapy: 1. has effects on cardiovascular risk markers (special blood tests which indicate how healthy your heart and arteries are) 2. affects the stiffness of the arteries 3. affects your heart rate and the capacity of your heart to respond to changes in body position 4. has different effects depending on whether you are taking estrogen / testosterone. We will assess these measures of health on one occasion in persons with cured acromegaly and normal GH levels and in persons with cured acromegaly who have GH deficiency and a contraindication to receiving GH. GH deficient individuals with no contraindication to receiving GH, will participate in the study for 12 months. Individuals with normal GH levels, or who are GH deficient and have a contraindication to receiving GH, will be asked to return for one more visit (without any interventions).

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00182091
The ClinicalTrials.gov registry entry for NCT00182091 describes a study currently listed as completed. 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 75 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Massachusetts General Hospital, which has 1,948 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 Growth Hormone Deficiency appearing as the primary indexed condition, and to 2 interventions — of which Saline 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: NCT00182091 reports 1 study location spanning 1 distinct geographic area — top geographies include Massachusetts. 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.
