ACURATE IDE: Safety and Effectiveness Study of ACURATE Valve for Transcatheter Aortic Valve Replacement
NCT03735667 · View on ClinicalTrials.gov ↗
Study Summary
To evaluate safety and effectiveness of the ACURATE Transfemoral Aortic Valve System for transcatheter aortic valve replacement (TAVR) in subjects with severe native aortic stenosis who are indicated for TAVR. As of 28-May-2025, Boston Scientific Corporation (BSC) announced the voluntary global discontinuation of the ACURATE product platform, including both the ACURATE neo2 and ACURATE Prime Aortic Valve Systems. BSC will no longer pursue regulatory approval for the device in the U.S. or other unapproved geographies.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03735667
The ClinicalTrials.gov registry entry for NCT03735667 describes a study currently listed as active not recruiting. 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 1,948 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Boston Scientific Corporation, which has 120 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 Aortic Stenosis appearing as the primary indexed condition, and to 4 interventions — of which ACURATE neo2™ Transfemoral TAVR System 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: NCT03735667 reports 20 study locations spanning 10 distinct geographic areas — top geographies include California, Arizona, Illinois. 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. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
