Primary Outcome Measures:
  • The difference in DRSP scale scores for the first 21 items, comparing average scores from the last 5 days before menses of the 3rd cycle in the treatment phase to average scores from the last 5 days before menses of the 2 run in cycles [ Time Frame: 3 cycles (1 cycle= 28 days) ]

Secondary Outcome Measures:
  • The difference in DRSP scale scores for the 3 functional impairment items, comparing the average over the last 5 days of daily scores from the 3rd cycle in the treatment phase to the average of daily scores from the 2 run in cycles [ Time Frame: 3 cycles ]
  • Descriptive statistics for total DRSP scale scores (sum of the first 21 items) of the last 5 days for each of the 2 run in cycles, each of the 3 cycles in the treatment phase, and the average of the 3 cycles in the treatment phase [ Time Frame: 3 cylces ]
  • Descriptive statistics for change in total DRSP scale scores (sum of the first 21 items) of the last 5 days from baseline to each cycle in the treatment phase and to the average of the 3 cycles in the treatment phase [ Time Frame: 3 cycles ]
  • Assessment of CGI scores [ Time Frame: 3 cycles ]
  • Adverse events [ Time Frame: Whole study period ]
  • Laboratory tests [ Time Frame: Whole study period ]
