Perivenous Dexamethasone Therapy: Examining Reduction of Inflammation After Thrombus Removal to Yield Benefit in Subacute and Chronic Iliofemoral DVT
NCT04858776 · View on ClinicalTrials.gov ↗
Study Summary
This is a study of a medical procedure that utilizes a commercially available catheter (the Bullfrog® Micro-Infusion Device) to locally deliver a commercially available anti-inflammatory drug (dexamethasone sodium phosphate injection) around the deep veins after DVT recanalization, where DVT symptoms were present for at least 14 days and no more than 60 days prior to recanalization. The goal of the study is to see if local anti-inflammation helps prevent re-thrombosis of the blood vessel and improvement in symptoms for up to 24 months after the initial DVT recanalization procedure.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04858776
The ClinicalTrials.gov registry entry for NCT04858776 describes a study currently listed as recruiting. 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 60 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Mercator MedSystems, which has 3 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 Iliofemoral; Thrombosis appearing as the primary indexed condition, and to 2 interventions — of which Perivascular dexamethasone 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: NCT04858776 reports 15 study locations spanning 13 distinct geographic areas — top geographies include Texas, Other, Connecticut. 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.
