Brief Summary:
The purpose of this study is to determine if Vascana, a novel topical formulation of nitroglycerin, is effective in the treatment and prevention of the symptoms associated with Raynaud's Phenomenon.

Condition or disease Intervention/treatment Phase
Raynaud Disease Drug: 0.9% nitroglycerin in TAM cream Drug: vehicle cream Phase 3

Detailed Description:
Raynaud's Phenomenon is a sometimes debilitating condition in which blood flow to the fingers or toes is compromised when a patient is exposed to cold or stress. Current therapies for Raynaud's are suboptimal because they are associated with significant side effects. In this study, patient responses to cold temperature exposures in a climate-controlled room after application of the study medication are measured.

Arm Intervention/treatment
Active Comparator: Vascana Drug: 0.9% nitroglycerin in TAM cream
0.5 g of Vascana (0.9% nitroglycerin in proprietary vehicle cream) is applied topically BID for one day before certain planned cold exposures, once just before same planned cold exposures, and, if needed, right after the start of symptoms during same planned cold exposures
Other Name: Vascana

Placebo Comparator: Vehicle Drug: vehicle cream
0.5g of vehicle cream is topically administered BID for one day before certain planned cold exposures, once just before certain planned cold exposures, and, if needed, right after the start of symptoms during certain planned cold exposures

Primary Outcome Measures :
  1. Response rate as measured by changes in severity of the Raynaud's symptom most bothersome to the individual patient (Pain, Numbness, or Tingling) [ Time Frame: 2 weeks ]

Secondary Outcome Measures :
  1. Changes from baseline in severity of each Raynaud's symptom (Pain, Numbness, and Tingling) [ Time Frame: 2 weeks ]
  2. Changes from baseline in duration of Raynaud's attacks [ Time Frame: 2 weeks ]
  3. Changes from baseline in number of Raynaud's attacks [ Time Frame: 2 weeks ]
  4. Changes from baseline in the Raynaud's Condition Score [ Time Frame: 2 weeks ]
  5. Changes in the maximum reduction in skin temperature [ Time Frame: 2 weeks ]
  6. Changes from baseline in overall disease severity measures [ Time Frame: 2 weeks ]
  7. Changes in the time to return to baseline skin temperature [ Time Frame: 2 weeks ]
