Primary Outcome Measures:
  • Shrinkage of Fibroids - Size of Fibroids [ Time Frame: 3 months (baseline to end of treatment) ] [ Designated as safety issue: No ]
    The primary outcome, fibroid volume, was calculated by an ellipsoid formula (π/6xd1xd2xd3) using orthogonal three-dimensional measurements taken from pelvic MRI scan. Individual volumes were summed to assess total fibroid volume for each woman, which were log-transformed before analysis. Women with paired MRI results were included in this intent to treat analysis, even if they did not take all study medication. Fibroids were included if they were seen on both studies.The absolute change in cm3 between baseline and end of treatment was calculated and its log was used for statistics and reporting the results in the data table below.


Secondary Outcome Measures:
  • Quality of Life [ Time Frame: 3 months (Baseline to end of treatment 1) ] [ Designated as safety issue: No ]
    The short form-36 (SF-36)and Uterine Fibroid Symptom Quality of Life (UFS-QOL) questionnaires were given before and at treatment end with scales of 0 - 100. SF-36 scales = mental and physical well-being. The UFS subscales are symptom severity, concern, activities, energy and mood, control, self-consciousness, sexual functioning compiled into an overall QOL score. Higher results indicate better QOL on all but symptom severity (higher = worse). The change in scores from baseline to end of treatment was calculated.
