Active clinical trials for "Varicose Ulcer"

The primary objective of this study is to demonstrate the non-inferiority of the 2-layer compression system Kit Biflex® with regard of the 4-layer compression system PROFORE® in the treatment of venous leg ulcers in terms of complete healing at 16 weeks.

The aim of this clinical trial is to investigate the efficacy (by monitoring the wound size reduction) and safety (by monitoring occurring adverse events) of the investigational medicinal product APZ2 after one single application on chronic venous leg ulcer wounds.

The aim of this study is to To evaluate the safety and tolerability of Platelet Rich plasma(PRP)/Thrombin mixture in treating chronic venous ulcers To evaluate efficacy of PRP/Thrombin mixture in treating chronic venous ulcers

Epidermal grafts are believed to promote healing by two mechanisms: graft take and the promotion of wound healing through the delivery of growth factors and the essential elements of tissue repair and wound healing.28 This study is intended to establish the superior effectiveness of epidermal grafting and multi-layer compression over that of multi-layer compression alone, in the treatment of venous leg ulcers. Millions of Americans are afflicted with painful, open, draining sores on their lower extremities. These sores are referred to as venous leg ulcerations (VLUs). Under the best of circumstances these ulcers require weeks or months to heal. Not uncommonly wound care specialists see patients who have suffered for years or faced amputation of the limb as their only option to alleviate the pain. Standard of care will result in healing in 50% of venous leg ulcers in 12 weeks. However, roughly half of patients suffering from venous ulcers will require advanced therapy. Epidermal grafting has been a reconstructive option for decades; however, to date there has not been a reliable and reproducible system to harvest epidermis. The CelluTome® Harvesting System permits the harvesting of epidermal blister grafts at the patient's bedside without the need for anesthesia. The grafts can be easily transferred to the wound bed. In case studies, epidermal grafting appeared to be effective in reducing wound size and accelerating closure of venous leg ulcers.

The purpose of this study is to evaluate and compare healing characteristics, reduction in the size of the wound and to measure complete healing of the wound following the application of a biologic product dressing instead of the alginate dressing along with standard debridement and compression therapy versus the standard of care treatment for VLUs. The biologic product that will be used in this study is called AmnioExCel™.

This study will examine differences in the process of wound-healing in patients treated with platelet rich plasma (a concentration of proteins derived from a patients own blood) applied to the wound as a gel; injected into the wound or surrounding tissue; or both; compared to patients treated with usual medical treatment . This study seeks to enroll patients who are 18 or older with a non-healing skin wound that is at least 30 days old. Only patients with Diabetic Foot Ulcers, Venous Ulcers, or Pressure Ulcers will be included in the study.

Assess the influence of HP802-247 on biochemical and cellular markers of inflammation in chronic venous leg ulcers

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

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.

The primary objective of the study is to demonstrate that the HM242-Gel performs at least comparably to INTRASITE Gel with regard to wound healing.
