Active clinical trials for "Varicose Ulcer"

A 12 month, multicenter, open-label registry to observe chronic venous insufficiency resulting in VLU treated with Varithena.

The goal of the Cellular and Tissue Based Therapy Registry (CTPR) for Wounds is to provide real world patient data from electronic health records submitted to meet Stage 2 Meaningful Use in order to understand the value of these products among patients with chronic wounds and ulcers. Randomized, controlled trials to establish product efficacy routinely exclude patients with the co-morbid conditions common to patients seen in usual clinical practice and thus the results of these RCTs tend to be non-generalizable. Little is known about the effectiveness of CTPs among typical patients.

Aims are: develop an Internet-based education programme about venous leg ulcer nursing care (ELC) evaluate the clinical, cognitive and economical outcomes of education programme Research questions are: 1. What are the cognitive outcomes of ELC (perceived knowledge, attitudes towards venous leg ulcer nursing care, theoretical knowledge level and practical knowledge)? Hypotheses for research question 1 are: Nurses using the ELC will have better knowledge (perceived, practical and theoretical knowledge) than those who will not use the ELC. Nurses using the ELC will have more positive attitudes towards venous leg ulcer nursing care than those who will not use the ELC. 2. What are the clinical outcomes of ELC (ulcer healing, ulcer size, treatment supplies)? Hypotheses for research question 2 are: Ulcer healing progresses better among patients who are taken care by nurses using the ELC. Ulcer sizes will be 10 % smaller among the patients cared for nurses using the ELC. Nurses using the ELC will use mire adequate treatment supplies than those who will not use the ELC. 3. What are the economical outcomes (treatment time and supply usage) of ELC? Hypothesis for research question 3 is: 1. The economical expenditures will be lower among nurses using the ELC. The ultimate aim is to promote evidence-based nursing care among patients with venous leg ulcer.

This observations safety study is intended for subject who participated in the 802-247-09-029 study with the investigational product HP802-247 for venous leg ulcers and received at least one application of HP802-247 or Vehicle (an inactive substance). This study is being done for the following purposes: to identify new adverse events, to examine ongoing adverse events not resolved in subjects who participated in the 802-247-09-029 trial, to record wound status, and to determine if there are differences in Health Related Quality of Life (HRQoL) associated with the treatment assignment from the 802-247-09-029 Trial. Investigational means that HP802-247 has not been approved by the U.S. Food and Drug Administration (FDA).

The goal of the Negative Pressure Wound Therapy Registry (NPWTR) for Wounds is to provide real world patient data from electronic health records submitted to meet Stage 2 Meaningful Use in order to understand the effectiveness and safety of various NPWT devices and methods among patients with chronic wounds and ulcers. Randomized, controlled trials to establish product efficacy routinely exclude patients with the co-morbid conditions common to patients seen in usual clinical practice and thus the results of these Randomized Controlled Trials (RCTs) tend to be non-generalizable. Little is known about the effectiveness of NPWT among typical patients. Patient registries are also ideal for assessing long term safety issues in these devices.

The objective of the study is to demonstrate that treatment with Apligraf reduces venous leg ulcer (VLU)-related pain and improves the quality of life (QOL) of patients with a painful VLU.

Given the propensity for venous leg ulcers to become refractory, long standing lesions, incorporating active biologic grafts into the standard compression therapy, has shown to accelerate wound healing. The two products to be compared in this study are both commonly used for the treatment of venous leg ulcers. Apligraf is considered a medical device by the FDA, and was cleared for the treatment of venous leg ulcers in 1998. It is a staple for the treatment of venous leg ulcers, and is widely used throughout the United States. It is composed of a type 1 collagen matrix in which human foreskin-derived neonatal fibroblasts are grown, and over which human foreskin-derived neonatal keratinocytes are then cultured and allowed to stratify. TheraSkin is composed of a split thickness skin graft harvested within 24 hours post-mortem, from an organ donor who has cleared the standard safety screenings. It is classified by the FDA as a donated tissue. Once harvested, the graft is sanitized according to FDA specifications, and cryopreserved, until it is delivered to the clinic for application to the foot ulcer. It is also a widely used treatment for diabetic foot ulcers. TREATMENT RATIONALE FOR THIS STUDY Chronic wounds of the lower extremities affect a substantial proportion of the population. Venous leg ulcers (VLU) account for 40-70% of lower extremity wounds. The standard of care for treatment of VLU's in wound centers in the United States is compression therapy combined with application of biologic graft materials to the wound bed. This study may assist physicians who treat VLU's by comparing efficacy and costs of two commonly used biologic graft materials for VLU's in a randomized prospective study. In addition to standard compression therapy, this investigation will be a head-to-head study comparing widely used bio-engineered skin substitute (Apligraf) to cryopreserved, human skin allograft (Theraskin). There is no randomized, prospective data comparing these two graft options in the treatment of VLU's.

This non-interventional, single-blinded, prospective, observational study assesses the planar distribution of leukocyte esterase in wounds by placing wound exudates soaked wound dressings in the DETEC® Esterase device during routine wound care. The output of the device is correlated with clinical determination of infection to assess the device efficacy in identifying presumptive infections.

The purpose of this study is to determine the relationship between wound alkalinity and the non-healing status of chronic ulcer wounds. It is hypothesized that wounds with an alkaline environment as indicated by DETEC pH will have a high chance of not healing over 12 weeks of wound care.

Chronically venous ulcer in lower extremities is a permanent and disabling disease. Venous insufficience is the main cause of chronic ulcer. There is a high prevalence and frequency of the disease, primarily among elderly people. Recently, electromagnetic field therapy has been tested on various diseases in musculoskeletal system with a beneficial effect. In recent years, there has been an increasing interest in using electromagnetic field therapy to treat chronically venous ulcer. The hypothesis of the investigators is that the electronic magnetic field therapy improves the healing process and reduces pain for patients suffering from chronically venous ulcer. The investigators assume that the bioactivity is affected by a cellular response which affects the DNA synthesis, transcription og protein synthesis.
