A Study to Investigate the Effect of AZD6234, AZD9550, and a Combination of AZD9550 and AZD6234 on Pharmacokinetics of Combined Oral Contraceptive Ethinyl Estradiol/Levonorgestrel in Healthy Female Participants Living With Overweight or Obesity

This study will measure the effects of multiple doses of AZD6234, AZD9550 and a combination of AZD9550 and AZD6234 given as injection(s) on pharmacokinetics (PK) of combined oral contraceptive (CoC) ethinyl estradiol (EE)/levonorgestrel (LEVO) in healthy female participants with obesity.

Inclusion Criteria: * All participants must have a negative pregnancy test at the Screening Visit and on admission to the Clinical Unit. * Females of childbearing potential must not be lactating and if heterosexually active, must agree to use an approved method of highly effective contraception. o Hormonal contraceptives and estrogen-containing hormonal methods of birth control are not permitted due to potential effect and influence on the results using a CoC assessment. * Females of non-childbearing potential must be confirmed at the Screening Visit. * Have a Body Mass Index (BMI) between 25 and 40 kg/m2, both inclusive and weigh at least 60 kg for Cohorts 1, 2, and 3 and a BMI of \> 30 kg/m2 for Cohort 4.
