Study Endpoints

Primary Endpoints

Red Blood Cell (RBC) Folate Level at 24 Weeks
Week 24

RBC folate=(\[whole blood folate\*100\]-\[plasma folate\*(100-hematocrit)\])/hematocrit

Plasma Folate Level at 24 Weeks
Week 24

Folate concentrations in plasma were determined by an appropriately validated microbiological assay.

Change From Baseline to Week 8 in Mean 24-hour SBP From the Ambulatory Blood Pressure Monitoring (ABPM) Measurements in Full Analysis Set (FAS) Population
Baseline to Week 8

The mean change in 24-hr ambulatory systolic blood pressure (SBP) from Baseline to Week 8 was calculated for the full analysis set. The change from baseline means was adjusted for center and baseline SBP.

Change From Baseline to Week 8 in Mean 24-hour SBP From the ABPM Measurements in Per Protocol Population
Baseline to Week 8

The mean change in 24-hr ambulatory systolic blood pressure (SBP) from Baseline to Week 8 was calculated for the per protocol (PP) population. The change from baseline means was adjusted for center and baseline SBP.

Frequently asked questions about Drospirenone, Ethinylestradiol/ Yasmin

What is drospirenone/ethinylestradiol (Yasmin) used for?

Drospirenone/ethinylestradiol, marketed as Yasmin, is an oral contraceptive combination. It is also being studied in neural tube defects and postmenopause. The development program includes a Phase 3 trial evaluating an oral contraceptive containing folate for neural tube defects and a Phase 2 study in postmenopausal women with prehypertension.

What does drospirenone/ethinylestradiol target?

Drospirenone/ethinylestradiol targets NR3C2 and PGR. Both targets are antagonized by the drug. Drospirenone acts as an antagonist at the mineralocorticoid receptor (NR3C2) and the progesterone receptor (PGR), which underlies its contraceptive and hormonal effects.

Who makes Yasmin (drospirenone/ethinylestradiol)?

Yasmin is developed by Bayer AG, which trades under the ticker BAYRY. Bayer AG is the company responsible for the drospirenone/ethinylestradiol program, including the related drospirenone/17ß-estradiol formulations known as Angeliq and BAY86-4891.

What phase is drospirenone/ethinylestradiol in?

Drospirenone/ethinylestradiol is in Phase 3 development. It is an investigational small molecule and is not described as FDA approved. The program has one completed Phase 3 trial and one completed Phase 2 trial, with no active trials currently listed.

What clinical trials is drospirenone/ethinylestradiol in?

The program includes NCT00468481, a completed Phase 3 trial titled Efficacy and Safety Study for an Oral Contraceptive Containing Folate, which enrolled 385 participants in the United States. It also includes NCT00420342, a completed Phase 2 trial of Angeliq and Prempro on blood pressure and sodium sensitivity in postmenopausal women with prehypertension, enrolling 92 participants.

Is Yasmin the same as Angeliq or BAY86-4891?

Yasmin is a brand name for drospirenone/ethinylestradiol. Related alternative names in the same program include drospirenone/17ß-estradiol, marketed as Angeliq and also known as BAY86-4891, as well as drospirenone/ethinylestradiol/methyltetrahydrofolate. These names refer to drospirenone-containing combinations developed by Bayer AG.
