Further study details as provided by University Hospital, Grenoble:

Primary Outcome Measures:
  • Mean change in the Raynaud's Condition Score (RCS) during treatment, as compared to placebo. [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    RCS is self-reported every day and averaged over 7-day periods

Secondary Outcome Measures:
  • Frequency of RP: number of RP attacks during treatment, as compared to placebo. [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    An attack is defined as an episode of pallor or cyanosis (with or without pain,tingling or numbness). The number of attacks is self-reported every day and averaged over 7-day periods

  • Patients' preference: comparison between the number of patients favoring a treatment to another. [ Time Frame: Every 3 weeks of treatment (week 3, 6 and 9) ] [ Designated as safety issue: No ]
  • Pain associated with RP: Mean change in the Raynaud's pain score during treatment, as compared to placebo. [ Time Frame: 7 days ] [ Designated as safety issue: No ]
    Pain associated with each attack is self-reported on a 10-point scale, and averaged over 7-day periods

  • Frequency and severity of adverse drug events during treatment, as compared to placebo [ Time Frame: 7 days ] [ Designated as safety issue: Yes ]
  • Microvascular reactivity: index of skin perfusion in response to local/regional cooling after a single dose of sildenafil, as compared to placebo (laboratory experiments) [ Time Frame: Week 1, 2 and 3 ] [ Designated as safety issue: No ]
