6. Participants, upon pelvic examination with speculum examination, must have a normal-appearing vulva other than atrophic changes, normal-appearing cervix other than atrophic changes (i.e., cervical stenosis and/or flushness with the vaginal wall) and normal-appearing vagina (without erosions, ulcerations, scarring, or evidence of dermatoses) other than atrophic changes (loss of ruggae, mucosal pallor, mucosal dryness, mucosal petechiae).

7. Have an intact uterus and no prior history of endometrial ablation.

8. Vaginal cellular cytology with = 5% superficial cells.

9. Vaginal pH > 5 at Screening Visit.

10. Endometrial thickness = 4 mm on transvaginal ultrasound.

11. Current on all recommended screening and management requirements for cervical cancer.

12. Normal mammogram report within 2 years of screening.

13. Normal manual breast examination by investigator at baseline.

14. Baseline hematology, clinical chemistry, urinalysis, prothrombin time/partial thromboplastin time (PT/PTT) and viral serologies for human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B surface antigen (HBsAg) all within normal limits OR accepted by the investigator and medical monitor as not clinically significant.

15. Normal 12-lead electrocardiogram (ECG).

16. Able to read, understand, and provide written informed consent and applicable data protection authorization after the nature of the study has been fully explained, and must be willing to comply with all study requirements.

21. Use of SERMs or AIs within 6 months prior to screening.
22. Use of anabolic or other steroids (including hormonal creams such as testosterone) within 4 weeks prior to Day 1.
23. Use of corticosteroids, > 5 mg/day prednisone or equivalent, for more than 4 weeks within 4 weeks prior to Day 1.
24. Participants with any self-reported active sexually transmitted disease and/or evidence of infection (including bacterial vaginosis) on vaginal examination by the investigator.
25. Participants with a urinary tract infection during screening as assessed by urine dipstick test with abnormal test findings (any positive result for leukocytes AND any positive result for nitrites).
26. Presence of clinically significant uterine fibroids.
27. Evidence of current alcohol or drug abuse in the past 60 days, including a positive result from the urine drugs of abuse or alcohol screen, or history of drug or alcohol dependence in the last 2 years, as assessed by the investigator.
