Active clinical trials for "Skin Ulcer"

The primary objective of this study is to provide preliminary data on the efficacy (digital ulcer net burden) and safety of riociguat administered 3 times daily (TID) in comparison to placebo in patients with scleroderma-associated digital ulcers

In an earlier clinical trial, RAPIDS-1, conducted in scleroderma patients with or without digital ulcers at baseline, bosentan significantly reduced the number of new digital ulcers versus placebo. The purpose of the present trial (RAPIDS-2) is to evaluate the prevention and healing effects of bosentan versus placebo on digital ulcers over a 24-week treatment period.

In a search for accessible treatment options, plant medicines used by different communities in Papua New Guinea have been tested to identify the sap of the tree, Ficus septica, as a promising antibacterial agent in vitro. This is an open label clinical trial using an interventional approach, to compare the effect of the antiseptic plant sap and standard topical antiseptic, on the rate of wound development prevention and bacterial growth. If shown to be effective, this readily available plant medicine can provide a zero-cost treatment option in remote areas of PNG.

Digital ulcers are one of the most prevalent complications of scleroderma (systemic sclerosis). There can be found few surveys on effect of topical agents on healing process of the ulcers. Thus, the aim of this study is to assess and compare the effects of topical diltiazem on SSc digital ulcers versus topical nitroglycerin.

Ulcers of the lower extremities, caused by chronic venous insufficiency and cellulitis are common in patients older than 65 years and cause a significant morbidity. Natural Matrix Bio polymer Membrane (NMBM) is a novel topical cosmetic cream containing a mix of natural waxes, sugars and lipids. The aim of this study is to test whether of Natural Matrix Bio polymer Membrane (NMBM) is effective as an adjunctive therapy to the treatment of venous stasis and post-erysipelas leg ulcers.

This is a pilot study analyzing the effect of sildenafil therapy on digital ulcers in systemic sclerosis. We want to analyze ulcer healing by measuring the size of digital ulcers and their count and analyze the effect of sildenafil on angiography.

To evaluate the effect of human amniotic membrane as a weekly dressing on chronic wounds in Epidermolysis Bullosa (EB) patients.

The aim of this clinical trial is to investigate the efficacy (by monitoring the wound size reduction of Chronic Venous Ulcers) and safety (by monitoring adverse events) of the medicinal product to be studied after two applications on the wound surface in patients with Chronic Venous Ulcers.

Split thickness skin grafting is the normal standard of care for wound closure. However, this is an invasive procedure and associated with pain also there can be additional donor site morbidity. Epidermal grafting is an emerging clinical alternative that is gaining clinical practise. Epidermal grafting (EG) is an alternative method of autologous skin grafting that 'harvests' a finer layer of skin than traditional Split thickness skin grafting (SSG). This potentially results in less pain and reduced donor site morbidity but only delivers several cell layers to the wound so may be less effective at healing a wound. It is not known if EG is an effective alternative to SSG. Further the mechanism to achieve wound healing may be different. EG promotes wound healing by expressing growth factors that accelerates wound healing and encourages keratinocyte migration. Whereas SSG is a transplant of several skin layers that integrated to the existing wound bed as a formal skin covering. The investigators wish to compare these two clinical practises; epidermal grafting and split thickness skin grafting in wound healing. Further to undertake a translational study to investigate the mechanism by which each technique achieves wound healing.

The aim of the study is to collect long-term efficacy, tolerability and safety data of bosentan in Systemic Sclerosis (SSc) patients suffering from ischemic digital ulcers (DUs).
