- Significant history or current evidence of chronic infectious disease, system disorder, organ disorder (including significant liver/kidney impairment) or other medical condition that in the Investigator's opinion would place the study participant at undue risk by participation or could jeopardize the integrity of the study evaluations.
- Participants with an intact uterus should have vaginal ultrasonography results to confirm an inactive endometrial lining. Participants with an endometrial thickness equal to or greater than 4 mm.
