Primary Outcome Measures
NameTimeMethod
The Change in Absolute Value From Baseline Menstrual Blood Loss (MBL) to the End-of-study MBL (Cycle 6)Baseline and up to 6 months

The MBL for each cycle included intermenstrual bleeding in addition to withdrawal bleeding. Baseline MBL was the composite MBL measured during each of the cycles during the Screening Phase. End-of-study MBL was measured during Cycle 6 of the Treatment Phase.

Percentage of Patients With Successful TreatmentAt 6 months

End-of-study MBL \< 80 mL and a decrease to a value no greater than 50% of the Baseline MBL was considered to be treatment success.

Secondary Outcome Measures
NameTimeMethod
Percent Change From Baseline MBL to End of Study MBL (Cycle 6)Baseline and up to 6 months

The percent change = {(End of Study MBL - Baseline MBL)/Baseline MBL} x 100.

Absolute Change From Baseline MBL to Mid-study MBL (Cycle 3)Baseline and up to 3 months

The MBL for each cycle included intermenstrual bleeding in addition to withdrawal bleeding. Mid-study MBL was measured during Cycle 3 of the Treatment Phase.

Percentage of Subjects Who Completed the Study in Levonorgestrel Intrauterine System (LNG IUS) GroupBaseline and up to 6 months
Total Number of Bleeding EpisodesBaseline and up to 6 months

A bleeding episode is defined as a light, normal or heavy bleeding, during a minimum of one day. In the LNG IUS group, each cycle has 30 days. In the MPA group, each menstrual cycle starts on the 1st bleeding day (withdrawal bleeding) and lasts until the last non-bleeding day before next withdrawal bleeding starts.

Percent Change From Baseline MBL to Mid-study MBL (Cycle 3)Baseline and up to 3 months

The percent change = {(Mid-study MBL - Baseline MBL)/Baseline MBL} x 100.

Total Number of Bleeding DaysBaseline and up to 6 months

In the LNG IUS group, each cycle has 30 days. In the MPA group, each menstrual cycle starts on the 1st bleeding day (withdrawal bleeding) and lasts until the last non-bleeding day before next withdrawal bleeding starts.

Percent Change in HemoglobinBaseline and up to 6 months
Total Number of Spotting and Bleeding DaysBaseline and up to 6 months

In the LNG IUS group, each cycle has 30 days. In the MPA group, each menstrual cycle starts on the 1st bleeding day (withdrawal bleeding) and lasts until the last non-bleeding day before next withdrawal bleeding starts.

Total Number of Spotting DaysBaseline and up to 6 months

In the LNG IUS group, each cycle has 30 days. In the MPA group, each menstrual cycle starts on the 1st bleeding day (withdrawal bleeding) and lasts until the last non-bleeding day before next withdrawal bleeding starts.

Percent Change in HematocritBaseline and up to 6 months
Percent Change in Serum FerritinBaseline and up to 6 months
Percentage of Patients With Improvement in the Investigator Global Assessment ScaleUp to 6 months

"Improved" is classified as 'very much improved', 'much improved', or 'improved' and "not improved" is classified as 'no change', 'worse', 'much worse', or 'very much worse'

Percentage of Patients With Improvement in the Patients Overall Assessment ScaleUp to 6 months

"Improved" is classified as 'very much improved', 'much improved', or 'improved' and "not improved" is classified as 'no change', 'worse', 'much worse', or 'very much worse'.
