5 Clinical Trials for Various Conditions
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 research study is to test the safety, tolerability, and effectiveness of Topical AmphiMatrix with Nitroglycerin (MQX0503) to relieve Raynaud's symptoms and increase blood flow to the fingers.
The purpose of this study is to investigate the efficacy and safety of a topical gel formulation of nitroglycerin, in comparison to a matching placebo, for patients with moderate to severe primary Raynaud's phenomenon or patients with Raynaud's phenomenon secondary to autoimmune diseases, such as scleroderma.
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.
The purpose of this clinical study is to determine the response to two different dosage strengths of a topical nitroglycerin gel in patients with Raynaud's Phenomenon. Patient fingers will be monitored for changes in blood flow and skin temperature. Symptoms of pain, tingling and numbness will also be monitored.
