ActiV.A.C.+ Compression Therapy Versus Compression Therapy Alone for the Treatment of Chronic Venous Ulcerations

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. The study will be conducted in the following manner: Prescreening, Screening, and Enrollment * Obtain informed consent * Assess patients for eligibility based on inclusion/exclusion criteria * Initial quality of life questionnaire completed * Target ulcer • If more than 1 wound is present on either leg; the target ulcer will be the one that is the largest in overall dimensions. All other ulcers will be treated per Standard of Care. * Photo/wound measurements * Venous studies (if necessary to confirm diagnosis) * Case Record Form (CRF) completed * Subjects will continue with Standard of Care until treatment initiation visit * If a patient is currently undergoing pump or pneumatic compression therapy, they must discontinue this treatment at least 2 week before the treatment initiation visit Treatment Initiation Visit and Randomization * Begin 2 weeks after the above enrollment visit - Confirm continued eligibility: * Photo/wound measurements (to be performed before and after debridement) * Exclude if wound size has decreased \> 35% - Randomization into the 2 treatment groups 1. ActiV.A.C. System Negative Pressure Therapy + Compression Therapy 2. Compression Therapy - Quality of life questionnaires completed \- CRF completed Subjects will have 1 visit in the clinic and 1 visit by a home nurse to change the dressing and Acti V.A.C ( if applicable) weekly Weekly Follow-Up * Visits must be ± 2 days of scheduled appointment * Photo/wound measurements (to be performed before and after debridement) * Change ActiV.A.C. System+ Compression Therapy or Compression Therapy * Quality of life questionnaires to be completed at weeks 4, 6 * CRF completed * If the subject is has not healed or healed, and the wound is not ready for a Split Thickness Skin Graft (STSG) or Bio-engineered Alternative Tissue (BAT)at the 6 week time point, then the patient will be exited from the study (see Close-Out) * If the subject has not healed within the 6 week interventional phase, but the wound is ready for a Split Thickness Skin Graft or Bio-engineered Alternative Tissue (BAT), they will be scheduled for a Split Thickness Skin Graft (STSG) or Bio-engineered Alternative Tissue (BAT) Close-Out * If the subject has not healed, they will be exited from the study at the 6 week time point * Photo/wound measurements (to be performed before and after debridement) * Close-out specific CRF completed * Complete quality of life questionnaires * Follow-up treatment plan with individual investigator Confirmatory Visit * If the target wound has healed within the 6 week interventional period, the subject will be scheduled for this confirmatory visit 2 weeks after wound has been deemed to be healed * Photo/wound measurements (to be performed before and after debridement) * Close-out specific CRF completed * Complete quality of life questionnaires * Follow-up treatment plan with individual investigator Split Thickness Skin Graft (STSG) or Bio-engineered Alternative Tissue (BAT)- If the wound is deemed ready for Split Thickness Skin Graft (STSG) or Bio-engineered Alternative Tissue (BAT) then the subject will either: * Be scheduled for surgery for application of a Split Thickness Skin Graft within 4 weeks * Have Bio-engineered Alternative Tissue (BAT)applied in the clinic within 4 weeks * Subject will continue with their intervention until the date of surgery * After Split Thickness Skin Graft, subjects will receive Standard of Care (SOC) utilizing the ActiV.A.C. ™ + Compression Therapy * After Bio-engineered Alternative Tissue (BAT), subjects will receive Standard of Care utilizing compression therapy * Photo/Wound Measurements (to be performed before and after debridement) * CRF completed * Subjects will have a f/u visit within 5-7 days for dressing change per Standard of Care Close-Out/Confirmatory Visit for Split Thickness Skin Graft (STSG) or Bio-engineered Alternative Tissue (BAT) \*2 weeks from the date of surgery (Split Thickness Skin Graft) or clinic application (Bio-engineered Alternative Tissue) * Regardless if the target wound is healed or not, the subject will be exited from the study * Photo/Wound measurements * Percent adherence for subjects who received a Split Thickness Skin Graft * Close-out specific CRF completed * Complete quality of life questionnaires * Follow-up treatment plan with individual investigator 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.
