  1. TR- transition; DB- double-blind; OLE- open-label extension; ITT- Intent-to-treat.
  2. Changes from TR baseline to DB endpoint or OLE endpoint were calculated using data from those patients belonging to ITT analysis set with DB or OLE endpoint. All data values are expressed as mean (SD) and p-values are based on change from TR baseline scores and calculated using paired t-test.
