Analysis of Adenosine on Sinus and Atrioventricular Nodal Conduction in the Pediatric Transplanted Heart
NCT02462941 · View on ClinicalTrials.gov ↗
Study Summary
Heart transplants save the lives of nearly 500 children in heart failure per year. Columbia is one of the largest pediatric heart transplant centers in the world, averaging 25 transplants per year, and providing ongoing care to nearly 250 children with transplanted hearts. After transplant, children are at increased risk to develop sudden onset of abnormally fast heart rates. This research project will study adenosine, a medication that is routinely used to slow fast heart rates in non-transplanted children (i.e. normal hearts), and its effects on the transplanted heart. Adenosine is often not used in patients with transplanted hearts because, based on prior limited research in adult patients, the standard adult dose may have a longer medication effect, producing a slower heart rate for an undesirable period of time. However, the current alternatives to adenosine treatment are either inappropriate for the pediatric age range, or have increased risk of unwanted side effects. This research project will answer two questions: is adenosine safe to give a child who has had a heart transplant, and will it be effective in treating the fast heart rate? All pediatric heart transplant patients undergo regular heart testing, known as a cardiac catheterization, one or more times per year. Three days before testing, participants will be asked to stop a regular medication, dipyridamole, because it slows the breakdown of adenosine in the body, and may increase its effects. (Of note, all patients that are on dipyridamole are also on aspirin, which gives a second line of heart protection, and will not be stopped.) After regular cardiac catheterization, all patients will already have intravenous (IV) access to give medication. Also, this setting allows the opportunity to have a back-up pacing catheter in the heart, ensuring that there will not be a longer than desired effect from the medication. Adenosine will be given per a low-dose protocol until either the medication effect is see

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02462941
The ClinicalTrials.gov registry entry for NCT02462941 describes a study currently listed as completed. It is categorized as Phase 1, 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 80 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Columbia University, which has 875 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 Atrioventricular Block appearing as the primary indexed condition, and to 2 interventions — of which Adenosine 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: NCT02462941 reports 1 study location spanning 1 distinct geographic area — top geographies include New York. 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.
