A Prospective, Randomized, Comparative Effectiveness Trial of the ActiV.A.C.+ Compression Therapy Versus Compression Therapy Alone for the Treatment of Chronic Venous Ulcerations
This is a prospective, randomized, comparative interventional human subject trial. Patients
with a chronic venous ulceration of the lower extremity will be enrolled into this study.
These wounds must be recalcitrant to the standard treatment regimen. There are a total of
two arms in this study. One group will be randomly assigned to receive Vacuum Assisted
Closure (V.A.C. or VAC) by means of the ActiV.A.C. + Compression therapy group consisting of
the application of this device along with compression therapy. The other group will be
randomly assigned into compression therapy only group. A total of 60 subjects will be
enrolled into this 6 week study. There will be a 2 week run-in period (prior to the onset of
the intervention) to ensure that the wound has not healed greater than 35% prior to
intervention and randomization. Wounds that heal within the 6 week trial period will have an
additional confirmatory visit 2 weeks after healing was identified.
If within the 6 week intervention period the wound bed is determined to be ready for a Split
Thickness Skin Graft (STSG) or Bio-engineered Alternative Tissue (BAT), the surgery or
clinic application will be scheduled within 4 weeks. Subjects deemed not to be a surgical
candidate, will have Bio-engineered Alternative Tissue (BAT) application in the clinic. This
includes patients who are medically unstable to receive a medical clearance for surgery or
otherwise not a candidate for Split Thickness Skin Graft (STSG) surgery (e.g. donor site
skin is compromised). During this period between the scheduled STSG surgery or BAT
application, the subjects will continue within the assigned treatment group. A confirmatory
visit will also occur 2 weeks after the application of a Split Thickness Skin Graft (STSG)
or Bio-engineered Alternative Tissue (BAT).
Patients diagnosed with a chronic venous ulceration will be assessed for study eligibility
during their initial clinical evaluation. Patients who meet the eligibility requirements
will be asked to enroll into the study (see Subject Recruitment). Subjects will be asked to
sign the informed consent form and receive a copy of the informed consent.

Application of Devices/Dressing
The usual consent forms that are part of the Standard of Care will be utilized per the
Center for Wound Healing at Georgetown University Hospital. All costs associated with the
clinic visit consistent with the Standard of Care will be billed in the customary fashion.
Standard of Care Wound Therapy (Debridement, Infection Control)
The surface of the venous wound will be washed and rinsed with a wound cleanser at every
visit per Standard of Care. The need for debridement (utilizing a scalpel and/or curette)
will be dependent of the amount of nonviable tissue and/or biofilm detected on the surface
of the wound. The decision to debride will be made by the individual investigator at each
visit. The use of topical enzymatic debriding agents will be at the discretion of the
investigator. Further, the investigator may use topical antimicrobials as needed. The use of
oral antibiotics will also be at the discretion of the individual investigator. No other
wound healing modalities including topically applied treatments will be allowed.
ActiV.A.C.® Therapy System
The ActiV.A.C.® Therapy System is an FDA approved device for the treatment of venous
ulcerations. The ActiV.A.C.® System will be applied in a customary manner per manufacturer's
recommendations. Acticoat Flex 7™ will be applied as the contact layer on the wound surface.
Acticoat Flex 7™ is a fenestrated, silver-coated (anti-microbial), knitted polyester
material that is routinely used as a contact layer dressing for chronic wounds. The open
cell foam is then applied over the top of the Acticoat Flex 7™ (cut to shape of the wound).
The adherent transparent occlusive material will be applied over the open cell foam. The
tubing is then attached after cutting a small aperture through the occlusive material.
Negative pressure will be set at 125 millimeters of mercury (mmHg) on continuous suction.
The sponge and canister will be replaced 2 times per week. This dressing change will take
place once in the clinic and once by the visiting home nurses. These nurses have had
in-service training on the proper application of negative pressure therapy and have
experience with its use.
Compression Therapy
Profore™ multi-layered compression bandaging system will be utilized. This includes the
application of a contact layer dressing using Acticoat Flex 7™. The compression bandage will
be applied per manufacturer's recommendations. The dressings will be changed 2 times per
week. This dressing change will take place once in the clinic and once by the visiting home
nurses. These nurses have had in-service training on the proper application of the
compressive dressing and have experience with its use.
Standard of Care Post Split-Thickness Skin Graft or Application of a Bio-engineered
Alternative Tissue (BAT)-
The application of a Split Thickness Skin Graft (STSG) or Bio-engineered Alternative Tissue
(BAT) will follow the Standard of Care. This Standard of Care applies to both interventional
groups. Split Thickness Skin Grafts will be applied in the operating room after debridement
of the venous wound which will be conducted per Standard Of Care. After the placement of the
Split Thickness Skin Graft onto the wound surface, a nonadherent dressing is placed onto the
graft followed by a silver impregnated dressing layer. The ActiV.A.C.™ open celled foam will
then be placed over the silver impregnated dressing in the customary fashion. Compressive
dressing will then be placed over the ActiV.A.C.™ occlusive material. The postoperative
dressings will be removed within 5-7 days. The wound site will then be redressed with a
nonadherent dressing as the contact layer, silver impregnated dressing, and Profore™. The
application of a BAT will take place in the outpatient clinic. This includes the debridement
of the wound and the application of a Bio-engineered Alternative Tissue (BAT) onto the wound
surface. The dressings include a nonadherent contact layer, followed by a silver impregnated
dressing, and finally a Profore™ compressive dressing.
