Outcomes
Primary Outcome Measures
Changes in blood flow in the fingers of the non-dominant hand after the induction of constriction of blood vessels by exposure to local cold temperatures.
Secondary Outcome Measures
Reduction in skin temperature recovery time and symptoms in the fingers of the non-dominant hand after the induction of constriction of blood vessels by exposure to local cold temperatures.

5. Study Description
Brief Summary
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.
Detailed Description
It is the intention of this protocol to study, in a controlled manner, the response of fingers of patients with Raynaud's phenomenon to two dosage strengths of a fast acting topical formulation of Nitroglycerin, MQX-503. Patients may have moderate to severe primary Raynaud's phenomenon or Raynaud's phenomenon secondary to autoimmune diseases such as scleroderma.
Quantitative changes in blood flow in the fingers of the non-dominant hand will be measured after the clinical induction of constriction of blood vessels by exposure to local cold temperatures. Secondarily, the quantitative reduction in skin temperature recovery time and symptoms of pain, tingling and numbness associated with Raynaud's phenomenon will be evaluated using a patient hand symptom analog assessment score. The frequency and severity of adverse events associated with MQX-503 will be assessed.
