Primary Outcome Measures :
  1. Number of Participants Who Experienced a Treatment-emergent Adverse Event (TEAE) [ Time Frame: Day 1 up to 4 weeks after last dose of study drug (median treatment duration was: TD-1473 20 mg - 142 days; TD-1473 80 mg - 180.0 days; TD-1473 200 mg - 158 days) ]
    A TEAE was defined as any AE with a recorded start date on or after the date of the first dose of study drug up through 4 weeks after the last dose of study drug. Any clinically significant changes in laboratory safety tests, electrocardiograms (ECGs) and vital signs, were also recorded as TEAEs.
