21 Clinical Trials for Various Conditions
This is a randomized, double-blinded, clinical trial assessing the therapeutic efficacy of Botulinum toxin A (Onabotulinumtoxin A) in treating scleroderma-associated Raynaud's syndrome. Each patient will undergo injection with a treatment dose of Botulinum toxin A in one randomly-selected hand, and the contralateral hand will be injected with sterile saline (placebo) to serve as a control. Study participants at the first study visit will complete study questionnaires, their hands will be assessed clinically for digital ulceration, and their hands will undergo non-invasive laser Doppler imaging to assess blood flow. After this initial assessment, the patients will undergo peri-arterial injection of Botulinum toxin A in one hand, and of sterile saline solution (placebo) in the other, in a randomized, blinded manner. Patient will report the severity of their Raynaud's symptoms weekly over the four month study period. At one month post-injection, the patient will complete study questionnaires, their hands will be assessed clinically for digital ulceration, and their hands will undergo non-invasive laser Doppler imaging. At four months post-injection, the patient will again complete study questionnaires, their hands will be assessed clinically for digital ulceration, and their hands will undergo non-invasive laser Doppler imaging. In addition, patient will be given the option of one week post-injection visit, at which point the same assessment will be performed. At the conclusion of the study, unblinding will occur.

Diosmiplex is a product marketed for the management of diseases due to venous and microvascular dysfunction. Raynaud's phenomenon is a disorder of characterized by spasm of small arteries and impaired microvascular flow. This study will examine the effects of diosmiplex on the frequency and severity of Raynaud's episodes in susceptible people.
Raynaud's Disease
Treating patients with Raynaud's phenomenon who have chronic pain and ulcerations is extremely challenging. Published reports and our previous work support our hypothesis that symptomatic patients experience relief of pain and healing of ulcerations with minimal adverse effects when treated with botulinum toxin type A (Btx-A) injections for Raynaud's phenomenon. The proposed study is the first clinical trial and prospective study designed to document whether or not 1) Btx-A injection relieves pain in a patient's hand affected with Raynaud's disease better than a placebo within 28 days of injection, and 2) Btx-A injection relieves pain associated with Raynaud's disease for longer than 28 days, improving patients' quality of life. Through this study we intend to further determine the effect of injected Btx-A on relieving chronic pain and ulcerations to the ischemic hand while characterizing the patients for whom this treatment is most effective.

Raynaud's Disease
The purpose of this study is to determine, in comparison to a placebo control, the response to two dosage strengths of a topical gel formulation of nitroglycerin, MQX-303, in the determination of finger blood flow and skin temperature in the fingers of patients with moderate to severe Raynaud's phenomenon, follwoing exposure to cold temperatures. Blood flow is determined by scanning laser Doppler equipment and skin temperature is measured using attached thermistor probes. Following baseline measurements, the study gel is applied, the hand is placed in a cold chamber, and then blood flow and skin temperature are monitored for the next two hours. Each patient will receive multiple doses on different days so that each can serve as his/her own control in interpreting the response.
Raynaud Disease, Raynaud Disease Secondary to Scleroderma, Raynaud Secondary to Other Autoimmune Disease
Juvenile secondary Raynaud's (ray-knows) Phenomenon is a disorder of the blood vessels in the fingers and sometimes can affect the toes, nose, or ears. Children with secondary Raynaud's Phenomenon have an underlying condition such as systemic lupus, scleroderma, or mixed connective tissue disease. When children with secondary Raynaud's are exposed to chilly or cold conditions from weather, cold temperatures, or even holding cold items from the refrigerator, their fingers may become cold, numb, hurt, and/or turn purple or white. The investigational drug, Pletal(cilostazol), which has been approved for other conditions, inhibits the ability of one type of blood cell, platelets, to form blood clots, and also widens narrowed blood vessels. It has been used in a variety of other conditions in which blood flow is decreased. This study will test the safety and effectiveness Pletal(cilostazol) to lessen the severity of the symptoms and decrease the number of secondary Raynaud's episodes in juvenile patients.
Raynaud's Disease
Juvenile primary Raynaud's (ray-knows) Phenomenon is a disorder of the blood vessels in the fingers and sometimes can affect the toes, nose, or ears. When children with primary Raynaud's Phenomenon are exposed to chilly or cold conditions from weather, cold temperatures, or even holding cold items from the refrigerator, their fingers may become cold, numb, hurt, and/or turn purple or white. Children with primary Raynaud's Phenomenon have no underlying systemic disease. The cause for their symptoms is unknown. The investigational drug, Pletal(cilostazol), which has been approved for other conditions, inhibits the ability of one type of blood cell, platelets, to form blood clots, and also widens narrowed blood vessels. It has been used in a variety of other conditions in which blood flow is decreased. This study will test the safety and effectiveness Pletal(cilostazol) to lessen the severity of the symptoms and decrease the number of primary Raynaud's episodes in juvenile patients.
Raynaud's Disease
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.
Raynaud's Syndrome
Raynaud's phenomenon (RP) is a common vascular disorder that affects approximately 10% of the general population. RP is associated with significant morbidity that may include loss of the digits due to repeated episodes of vasospasm of the digital arteries in addition to significant impairment of quality of life. It is well known that cold exposure precipitates episodes of RP, but the mechanism for cold sensitivity is not known, and treatment of RP is not satisfactory to the patients and their physicians. The goal in this study is to test the possibility that non invasive vagus nerve stimulation (nVNS) with gammaCore which is already approved by the FDA for headaches and migraines may be an effective and well tolerated therapy for Raynaud's Phenomenon.
