This study will measure the effects of multiple doses of AZD6234 and a combination of AZD6234 and AZD9550 given as injection(s) on pharmacokinetics (PK) of combined oral contraceptive ethinyl estradiol (EE)/levonorgestrel (LEVO) in healthy female participants with obesity.
This is a Phase I, open-label, single-sequence, multiple-cohort study which will be performed at multiple study sites in healthy females of childbearing and non-childbearing potential. The purpose of this study is to investigate the effect of AZD6234 and a combination of AZD6234 and AZD9550 on the PK, safety and tolerability of a combined oral contraceptive, ethinyl estradiol/levonorgestrel (EE/LEVO). The study will have 2 cohorts, and each cohort will consist of 5 periods which include, Screening, Start, Up-titration, Maintenance, and Follow-up periods.
