Trial Information

RNA Expression Analysis Of Endometrial Biopsies Comparing Placebo, Bazedoxifene/ Conjugated Estrogens And Raloxifene

The termination date was June 23, 2010. The study was terminated because the endometrial
biopsy blocks from the 3115A1-303 study that were to be used for this study need to be
retained and accessible in case of a regulatory inspection of the 303 protocol.
Additionally, the Brazilian sites were not likely not to receive national IRB (CONEP)
approval, and enrollment could not be met without the inclusion of these subjects. The
study was not terminated due to safety concerns.

Inclusion Criteria:

- Each subject must have participated in study 3115A1-303 and must have satisfied all
of the following criteria:

- Has completed 24 months of treatment.

- Was at least 80% compliant with study drug administration.

Exclusion Criteria:

- Endometrial biopsy at baseline, month 6 or month 24 that were technically

- Did not have an endometrial biopsy at all of the required timepoints (baseline, month
6, month 24)
