Perivenous Dexamethasone Therapy: Examining Reduction of Inflammation After Thrombus Removal to Yield Benefit in Acute Femoropopliteal DVT (DEXTERITY-AFP)
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 up to 14 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.
• Provision of signed and dated informed consent form prior to receiving any non-standard of care, protocol-specific procedures.
• Stated willingness to comply with all study procedures including completion of questionnaires and follow-up visits and availability for the duration of the study.
• Male or female, aged 18 to 89 years.
• For females of reproductive potential: use of highly effective contraception (abstinence is acceptable) for at least 1 month prior to study treatment (unless they had given birth within the 1 month prior to study treatment), and agreement to use such a method for at least 30 days after study treatment.
• Onset of acute DVT symptoms of 14 days or less prior to initial intervention in the study limb.
• Ability to take oral medication and be willing to adhere to the prescribed anti-coagulant regimen.
• Post-procedural prescription for at least 28 days low molecular weight heparin followed by therapeutic anticoagulant of investigator's choice for 12 months minimum as part of post-interventional medication regimen.
• Minimum of 28 days of prescribed antiplatelet agent (aspirin or P2Y12 inhibitor) for patients receiving stents.
• DVT located in any of the major femoropopliteal veins (common femoral, femoral, and/or popliteal above the tibial plateau), with possible extension downstream into the iliac veins.
⁃ Successful recanalization of the target vein with removal of acute thrombus.
