Active clinical trials for "Raynaud Disease"

This is a Phase 3, multicenter, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of iloprost on the frequency of and relief from symptomatic digital ischemic episodes in subjects with systemic sclerosis.

The purpose of this study is to analyze the effects of an intervention with galvanic electrical current on the number of attacks , temperature, pain, peripheral blow flow and upper limb functionality in patients with Raynaud's Phenomenon in comparison to a control group that will maintain their habitual treatment.

The primary objective of the study is to determine the activity of selexipag on Raynaud attack frequency in subjects with Raynaud's Phenomenon (RP) secondary to Systemic Sclerosis (SSc).

Early phases of systemic sclerosis is characterized by inflammatory and microvasculature alterations. Sildenafil citrate has been shown to have vasodilatory effects and to enhance vasculogenesis. The purpose of this study is to evaluate the effect of sildenafil citrate on hand blood flow of patients with systemic sclerosis, using Laser Doppler Imaging.

The prevalence of Raynaud phenomenon (RP), a reversible vaso-constriction with skin discoloration, is 5-10% in general population. Often conventional measures such as warming up or minimizing exposure to cold are not enough and many patients require treatment with a vasodilator therapy. A recent study showed a good efficacy and safety profile of sildenafil, a selective inhibitor of cGMP specific phosphodiesterase type 5 (PDE5) in RP. Here, the investigators aim to examine the efficacy and safety of Udenafil, a newer PDE5 inhibitor, as compared to amlodipine, a well known calcium channel blocker, in the treatment of secondary RP in Korean patients.

The purpose of this clinical study is to compare the pharmacokinetic profiles of a topical cream formulation of 0.9% nitroglycerin, MQX 503, and Nitroglycerin Ointment 2%, USP.

The Purpose of this study is to determine the response to two different strengths of a topical gel containing nitroglycerin in patients with Raynaud's disease.

The purpose of this study is to determine the ability of Vascana (0.9% nitroglycerin topical cream) to treat and prevent the symptoms experienced by subject's with Raynaud's Phenomenon. The symptoms of this disease include pain, tingling, and numbness in the fingers of the affected hand or hands.

The investigators are studying a medical condition known as Raynaud's Phenomenon (RP). RP is a painful condition in which cold surroundings or stressful events trigger pain, a cold sensation, and in severe cases, sores and ulcers on one's fingers. The investigators think that RP results from problems with some of the components of the blood vessels, surrounding nerves, and some of the circulating messengers in the bloodstream. Although there are many different medicines that are currently used to treat RP, the investigators have not yet found a cure for severe cases of this condition. Furthermore, the investigators have found few medicines that show consistent healing of the ulcers that may be associated with RP. Some of the treatments include medicines that are used to treat high blood pressure known as calcium channel blockers. Medications that thin the blood (anticoagulants) such as aspirin have also been used to treat RP. In this study, the investigators will investigate a new treatment for RP known as Botulinum toxin A. Botulinum toxin is a chemical that is temporarily toxic to nerves, but has been approved by the government for the treatment of several other conditions including but not limited to: excessive sweating, neck pain associated with a condition known as cervical dystonia, uncontrollable forcible closure of the eyelids known as blepharospasm, and a condition known as strabismus in which the eyes are not in alignment with one another. This study will aim to greatly improve the quality of life and pain associated with RP. Previous studies also support the chance that Botulinum toxin will help to heal some of the ulcers associated with RP. Although there is no current standard of care, many of the patients in the study will have already failed or are unable to tolerate commonly used treatments such as lifestyle modifications, calcium channel blockers, nitroglycerin, and anticoagulants. If the patient chooses to participate in the study, he/she will be randomly assigned to receive an injection with Botulinum toxin in either the left or right hand. The other hand will be injected with saline solution. Neither the patient nor the physician or research personnel seen in follow-up will know which hand is injected with Botulinum toxin.

The investigators propose that tadalafil will increase digital blood flow and improve the symptoms and signs of secondary Raynaud's phenomenon.
