Study of Growth Hormone Inhibition Using Pegvisomant in Severe Insulin Resistance
NCT05470504 · View on ClinicalTrials.gov ↗
Study Summary
Background: Lipodystrophy (LD) syndromes are a group of rare disorders that affect how a person s body can store and use fat tissue. Many people with LDs become severely insulin resistant. Some people are insulin resistant because of a variant in the insulin receptor gene. Insulin resistance causes many health problems. Objective: To learn if blocking the effects of growth hormone in the body will help people with severe insulin resistance. Eligibility: Adults aged 18 to 65 years with either a known variant in the insulin receptor gene or with a diagnosis of partial LD. Design: Participants will have 2 hospital stays, about 1 month apart. Each stay will be 3 or 4 nights. During each hospital stay, participants will have many tests. They will have a physical exam with blood tests. They will have all of their urine collected for a 24-hour period. They will have scans to measure their muscle, bone, and fat tissues. They will have tests to measure metabolism and insulin sensitivity. They may have an optional biopsy of fat tissue. During the first hospital visit, participants will learn how to give themselves shots of a drug (pegvisomant) that blocks growth hormone. The drug is injected under the skin. Participants will continue to give themselves these shots once a day at home. After the first hospital visit, participants will talk on the phone with members of the study team once each week. After 2 weeks they will have blood drawn for tests. Participants will stop the shots after the second hospital visit.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05470504
The ClinicalTrials.gov registry entry for NCT05470504 describes a study currently listed as recruiting. It is categorized as Phase 2, 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 25 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), which has 375 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 Partial Lipodystrophy 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: NCT05470504 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.
