Filter by: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.
The effect of bosentan on digital ulcers (DU) was studied in two randomized placebo-controlled trials (RAPIDS-1 and RAPIDS-2). A limitation of these studies was the heterogeneous study population. More importantly, there were no endpoints that assessed changes in vasculopathy and / or perfusion. Laser Doppler imaging has been shown to effectively demonstrate blood flow restrictions in the hands of patients with Systemic Sclerosis (SSc). The relation between blood flow restriction in the hands measured by laser Doppler imaging and the extent of DU disease has not been studied. The current study will attempt to demonstrate this relation. In addition, the impact of bosentan on the blood flow in the hands, in a defined cohort of SSc-DU patients with a history of DU within the past 2 years and a clinically relevant reduction of blood flow in the hands, will be assessed.
The CAP study is a multicenter, observational, clinical study in patients with systemic sclerosis. The study aims at determining the usefulness of nailfold videocapillaroscopy and patient-specific disease-related factors in predicting the occurrence of digital ulcers within a 6-month observation period. Patients with cutaneous forms of systemic sclerosis (limited or diffuse), with or without history of digital ulceration are eligible. The study will enroll 500 patients at 70 centers.
Raynaud's phenomenon (RP) associated with scleroderma is a difficult problem to treat. Many patients develop ischemic digital ulcers due to severe RP that causes considerable morbidity and adversely affects the quality of life. In an earlier study, we have observed marked improvement in RP attacks and rapid healing of digital ulcers following therapy with phosphodiesterase V inhibitor, Tadalafil. In the present multicentric study we aim to study the efficacy of Tadalafil in patients continuing to have RP attacks despite using at least one or more vasodilators.
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).
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.
