Tuberous Sclerosis Complex Natural History Study: Renal Manifestations
NCT00598455 · View on ClinicalTrials.gov ↗
Study Summary
Eighty percent of patients with tuberous sclerosis complex (TSC) have renal angiomyolipomata. These lesions grow and can lead to significant morbidity by hemorrhage or renal failure. Understanding the natural history of these lesions and understanding which lesions may be more prone to grow quickly or develop aneurysms that predispose to hemorrhage will greatly assist clinical care of patients with TSC. The objective is to test the hypothesis that serial MR and CT imaging will allow objective, reproducible quantification of angiomyolipoma growth by volumetric analysis, and analysis of lesions characteristics will identify angiomyolipomata with rapid growth potential that would require intervention. The specific aim of this proposal is to collect clinically obtained serial abdominal imaging from the Tuberous Sclerosis Natural History Consortium Centers and analyze the volume and adiposity of the individual angiomyolipomata. The growth rate is hypothesized to have an inverse relationship to adiposity. Yearly renal MR or CT imaging will be performed of patients with TSC. The images will be coded at the site of acquisition, and transferred via VPN to a secure server at Cincinnati Children's Hospital Medical Center. Using innovative imaging processing software (Cincinnati Children's Hospital Image Processing Software (CCHIPS), the image data will be segmented to reveal various tissue components based on signal intensities. Different signal intensities can differentiate normal renal parenchyma, and renal angiomyolipomata. Using the imaging data and the novel software, the volume of an individual angiomyolipoma, as well as the adiposity will be determined. Imaging at enrollment (year 1) will serve as baseline. At years two and three, the lesions will undergo repeat analysis. Angiomyolipoma growth rates and adiposity over three years will be analyzed to test the hypothesis above.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00598455
The ClinicalTrials.gov registry entry for NCT00598455 describes a study currently listed as completed. It is categorized as an unspecified phase, 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 450 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Children's Hospital Medical Center, Cincinnati, which has 715 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 Tuberous Sclerosis Complex appearing as the primary indexed condition, and to 0 interventions. 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: NCT00598455 reports 1 study location spanning 1 distinct geographic area — top geographies include Ohio. 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.
