Etidronate for Arterial Calcifications Due to Deficiency in CD73 (ACDC)
NCT01585402 · View on ClinicalTrials.gov ↗
Study Summary
Background: * Arterial Calcifications due to Deficiency in CD73 (ACDC) is a rare genetic disease. People with ACDC develop calcification in the arteries of the lower extremities as well as calcium deposit in the joints of the fingers, wrists, ankles and feet. The lower extremities calcification causes claudication because of severe ischemia requiring at time revascularization procedures. the calcium deposits in the joints causes severe debilitating pain in the hands and feet. Currently, there are no standard treatments for ACDC. * Etidronate is a bisphosphonate that interferes with bone metabolism. It is approved to treat Paget's disease, a condition in which the bones are soft and weak and may be deformed, painful, or easily broken. It is also used to treat high blood calcium levels. Researchers want to see if it can be used to treat the calcifications of ACDC and improve pain and blood flow in the lower extremities and arthritic pain of the hands and feet. Objectives: \- To see if etidronate is a safe and effective treatment for ACDC. Eligibility: \- People between 18 and 80 years of age who have been diagnosed with ACDC. Design: * Participants will be screened with a physical exam and medical history. They will also have imaging studies, including CT scan of the lower extremities, x-rays and DEXA bone scans, before starting treatment. Blood and urine samples will be collected. An exercise tolerance test will also be given and ABI (ankle brachial index will be measured. * Participants will take etidronate by mouth once a day for 14 days every 3 months. They will be assigned an individualized 6- month drug schedule to follow. * Participants will have regular study visits throughout the treatment period. These visits will involve imaging studies, full dental exams, and blood and urine tests. Participants will also have exercise tolerance tests and ABIs measured. * Participants may also provide tissue samples for further study. * Treatment will continue for up

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01585402
The ClinicalTrials.gov registry entry for NCT01585402 describes a study currently listed as completed. 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 7 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Heart, Lung, and Blood Institute (NHLBI), which has 381 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 Arterial Calcification appearing as the primary indexed condition, and to 2 interventions — of which Etidronate 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: NCT01585402 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.
