A Study to Investigate the Effect of JNJ-63623872 at Steady-state on the Steady-state Pharmacokinetics of Ethinylestradiol and Norethindrone

A Phase 1, Open-label Study in Healthy Female Subjects to Investigate the Effect of JNJ-63623872 at Steady-state on the Steady-state Pharmacokinetics of Ethinylestradiol and Norethindrone

The purpose of this study is to evaluate the effect of steady-state concentrations of JNJ-63623872 on the steady-state pharmacokinetics of ethinylestradiol and norethindrone in healthy female participants.

This is a Phase 1 and open-label study. The study consists of Screening Phase (less than or equal to (<=) 28 days before Day 1), Treatment Phase (Day 1 up to Day 78) and Follow up Phase (10 to 14 days after last study drug intake or, if an adverse event occurs, 30 to 35 days after last study drug intake). Treatment phase will consist of three Oral Contraceptive (OC) cycles (each cycle consists of 21 days of ethinylestradiol/norethindrone followed by 7 pill-free days). The duration of the treatment phase, including the OC-free period of Cycles I and II, will be 78 days. Blood samples will be collected for measurement of pharmacokinetic (Pk) parameters. Participants' safety will be monitored throughout the study.

Inclusion Criteria:

• Participant must be willing and able to adhere to the prohibitions and restrictions specified in the protocol
• Participants must, if heterosexually active with a partner who is not vasectomized (confirmed sterile), be practicing an effective method of contraception before entry and agree to continue to use two effective methods of contraception throughout the study and for at least 30 days after receiving the last intake of oral contraceptive (OC) plus JNJ-63623872 on Day 77
• Participants must have a negative serum pregnancy test at screening and a negative urine pregnancy test on Day 1 of Cycle I
• Participants must agree not to donate eggs (ova, oocytes) during the study and for at least 90 days after receiving the last intake of OC plus JNJ-63623872 on Day 77
• Participants must have a Body Mass Index (BMI); between 18.0 and 30.0 kilogram per square meter (kg/m^2) (extremes included)

Exclusion Criteria:

• Participant has a history of current clinically significant medical illness including (but not limited to) cardiac arrhythmias or other cardiac disease, hematologic disease, coagulation disorders (including any abnormal bleeding or blood dyscrasias), lipid abnormalities, significant pulmonary disease, including bronchospastic respiratory disease, diabetes mellitus, hepatic or renal insufficiency, thyroid disease, neurologic or psychiatric disease, infection, or any other illness that the Investigator considers should exclude the participant or that could interfere with the interpretation of the study results
• At screening, participants with one or more of the laboratory abnormalities specified in the protocol as defined by the World Health Organization (WHO) Toxicity Grading Scale
• Participant with a past history of heart arrhythmias (extrasystole, tachycardia at rest), history of risk factors for Torsade de Pointes syndrome (example, hypokalemia, family history of long QT Syndrome)
• Participants with any history of clinically significant skin disease such as, but not limited to, dermatitis, eczema, drug rash, psoriasis, food allergy, or urticarial
• Participants with a history of clinically significant drug allergy such as, but not limited to, sulfonamides and penicillins, or drug allergy diagnosed in previous studies with experimental drugs
