A Study to Investigate the Pharmacokinetics of Ethinyl Estradiol and Levonorgestrel When Given Alone and in Combination With Baxdrostat in Healthy Females of Non-childbearing Potential
CompletedPhase 1
Sponsor: AstraZeneca
Conditions: Healthy Participants
Interventions: EE/LNG, Baxdrostat
Countries: United States
The main purpose of the study is to assess the effect of multiple doses of baxdrostat on the pharmacokinetics (PK) of a single dose of combined oral ethinyl estradiol (EE) and levonorgestrel (LNG). Safety and tolerability of baxdrostat will be assessed during the study.
