Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To assess the endometrial safety of an oral test preparation containing 4 mg drospirenone (Test IMP: Drospirenone 4 mg film-coated tablet) after multiple dose administration of 4 mg drospirenone for a total duration of 13 cycles of 28 days each: 24 days of active treatment followed by 4 days placebo treatment per treatment cycle.;Secondary Objective: - To assess the endometrial thickness under treatment with the test product, - To assess the pattern of vaginal bleeding under treatment with the test product, - To assess the safety of the test product on the basis of safety clinical and laboratory examinations (at the beginning and at the end of the trial) and registration of adverse events and/or adverse drug reactions based on evaluation of adverse events.;Primary end point(s): Rating of endometrial biopsy (according to Lindgren et al., 1992). This endpoint undergoes descriptive statistical evaluation.;Timepoint(s) of evaluation of this end point: After end of the clinical part and database closure. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): a) Endometrial thickness measured by transvaginal sonography, b) Number and percent of subjects with scheduled bleeding, spotting, and unscheduled bleeding per cycle, c) Number and percent of days per cycle with scheduled bleeding, unscheduled bleeding, or spotting. Additional endpoints: a) Incidence of adverse events and serious adverse events, b) Changes from baseline in the results of clinical examination and vital signs c) Changes from baseline in safety laboratory parameters (hematology, blood coagulation, biochemistry, urinalysis) d) Changes from baseline in the results of gynecological examination e) Results of pregnancy tests. These endpoints undergo descriptive statistical evaluation. ;Timepoint(s) of evaluation of this end point: After end of the clinical part and database closure. | — |
