Encore PFO Closure Device - The PerFOrm Trial

What the Registry Record Tells You About NCT05537753

The ClinicalTrials.gov registry entry for NCT05537753 describes a study currently listed as 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 500 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Encore Medical, which has 1 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 Patent Foramen Ovale appearing as the primary indexed condition, and to 2 interventions — of which Encore PFO closure device 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: NCT05537753 reports 8 study locations spanning 8 distinct geographic areas — top geographies include Arkansas, California, Florida. 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.
