Arms Assigned Interventions
2
Placebo - Topical AmphiMatrix
Drug: Topical AmphiMatrix
Individual pouch applicators containing 0.5 grams of Topical AmphiMatrix. Each dose is intended for topical usage on both hands up to five minutes before an anticipated Raynaud's attack or up to 5 minutes after the beginning of an actual Raynaud's attack. Limited to four applications per day; minimum of two hours between applications.
Active Comparator: 1
Topical AmphiMatrix with Nitroglycerin
Drug: Nitroglycerin
Individual pouch applicators containing 0.5 grams of Topical AmphiMatrix with Nitroglycerin. Each dose contains 4.5mg of Nitroglycerin. Each dose is intended for topical usage on both hands up to five minutes before an anticipated Raynaud's attack or up to 5 minutes after the beginning of an actual Raynaud's attack. Limited to four applications per day; minimum of two hours between applications.

Detailed Description:

The purpose of this clinical study is to determine, in a controlled fashion, the ability of a topical formulation of Nitroglycerin, MQX-503, to improve the patient's health assessment as indicated by patient and physician assessments, decrease the frequency of Raynaud's events, decrease the duration of Raynaud's events, and decrease the symptoms (pain, tingling, numbness) in the fingers of Raynaud's patients. The study will include patients with moderate to severe primary Raynaud's Phenomenon (RP) and with moderate to severe Raynaud's Phenomenon secondary to autoimmune diseases, such as scleroderma.
