Outcome Measures

Primary Outcomes (1)

  • Change in Proportion of Days With Pain Due to Sickle Cell Disease as Measured by an eDiary

    To investigate the efficacy of 2 different doses of ticagrelor versus placebo in reducing the number of days with pain due to sickle cell disease.

    Baseline through Week 12

Secondary Outcomes (2)

  • Average of the Daily Worst Pain Values Reported Via eDiary

    Baseline through Week 12

  • Change in Proportion of Days With Analgesic Use Measured by an eDiary

    Baseline through Week 12

Other Outcomes (2)

  • Number of Major Bleeding or Clinically Relevant Non-major Bleeding Events (Patients)

    Baseline through Week 12

  • Number of Major Bleeding or Clinically Relevant Non-major Bleeding Events (Events)

    Baseline through Week 12
