The purpose of the study is to test non-inferiority of chronic Venous Leg Ulcer (VLU) area closure at 16 weeks with a dual action pneumatic compression device compared to multi-layer bandaging.

Official Title

Randomized Trial Comparing a Dual Action Pneumatic Compression System Against Multi-Layer Bandaging Systems: A Non-inferiority Study


Participants with a chronic venous leg ulcer will participate in a 2 week run in phase using standard of care multi-layer bandaging before being randomly assigned to either treatment using a dual action pneumatic compression device or multi-layer bandaging for up to 16 weeks. Participants will be seen in clinic for treatment, evaluation, complete symptom and quality of life questionnaires.

  • Active ulceration (CEAP classification of C6)
  • Ulcer duration: Non healing VLU ≥ 1 month but not greater than 24 months.
  • Ulcer size ≥ 2cm2 ≤ 50cm2
  • Three or fewer separate full thickness ulcers on the study limb.
  • Leg circumferences within the following range:Ankle - 12 to 44cm; Calf - 22 to 60cm; Below knee - 22 to 68cm
  • Must be able and willing to provide informed consent prior to study participation.

You CAN'T join if...

  • Target ulcer or any other ulcer on the study limb involves exposure of tendon, muscle, or bone.
  • Target ulcer is of non-venous etiology (sickle cell anemia, necrobiosis lipoidica diabeticorum, pyoderma, malignancy).
  • Treatment of the target ulcer with living cellular therapy within 30 days of the time of projected randomization.
  • Endovenous ablation or other venous surgery within one week of enrollment
  • History of skin sensitivity to any of the components of AT, multi-layer bandages or compression garments.
  • History of an acute deep vein thrombosis (DVT) or pulmonary embolism (PE) within the last three (3) months.
  • Acute thrombophlebitis within the last six (6) weeks.
  • History of pulmonary edema or decompensated congestive heart failure within six (6) weeks of screening.
  • Currently has an active infection of the skin on the target limb such as cellulitis requiring antibiotics.
  • History of target limb cancer within the last two years with the exception of treated non-melanoma skin cancer unless ulcer biopsy performed at screening is negative for neoplasia.
  • Active cancer receiving chemotherapy and/or radiation therapy.
  • Poorly controlled diabetes with an HbA1c value of > 12% within the past three (3) months.
  • Changes to medications that affect edema within the last 30 days prior to enrollment (e.g. diuretics, calcium channel blockers of the dihyropyridine class, pioglitazone, cox-1 inhibitors, pregabalin, and gabapentin, diltiazem or fluctuating doses of systemic steroids).
  • Use of systemic corticosteroids requiring daily administration at doses greater than 5mg of Prednisone per day or equivalent for greater than two weeks.
  • Currently pregnant or trying to become pregnant.
  • Inability or unwillingness to participate in all aspects of study protocol.
  • Exhibit any condition which, according to the Investigator, justifies the subject's exclusion from the study, such as a medical condition where an increase in venous or lymphatic return is undesirable.
  • Currently participating in another clinical trial.

Additional Exclusion Criteria after two week run-in:

  • If ulcer area has decreased by greater than 30% compared to baseline area.
  • Ulcers measuring less than 1.5cm² after the run in will be excluded.
  • Any ulcer appearing to have evidence of infection.
  • Ulcers increasing in size greater than 50% after run in also excluded.
  • If the sum of the ulcer areas on the study limb is > 50cm2 the subject is excluded.
