A Study in Healthy Female Participants to Investigate the Effect of JNJ-56136379 at Steady-state on the Single-dose Pharmacokinetics of Ethinylestradiol and Drospirenone (Oral Contraceptive) and on the Single-dose Pharmacokinetics of Midazolam (Probe Substrate for Cytochrome P450 3A4)

A Phase 1, Open-label Study in Healthy Female Subjects to Investigate the Effect of JNJ-56136379 at Steady-state on the Single-dose Pharmacokinetics of Ethinylestradiol and Drospirenone (Oral Contraceptive) and on the Single-dose Pharmacokinetics of Midazolam (Probe Substrate for Cytochrome P450 3A4)

The main purpose of this study is to evaluate the effect of steady-state concentrations of JNJ-56136379 on the single-dose pharmacokinetics (PK) of drospirenone and ethinylestradiol (oral contraceptive [OC]) in healthy female participants and to evaluate the effect of steady-state concentrations of JNJ-56136379 on the single-dose PK of midazolam (sensitive probe substrate for CYP3A4) in healthy female participants.

Inclusion Criteria:

• Healthy on the basis of physical examination, medical history, and vital signs performed at screening. If there are abnormalities, the participant may be included only if the investigator judges the abnormalities to be not clinically significant or to be appropriate and reasonable for the population under study. This determination must be recorded in the participant's source documents and initialed by the investigator
• healthy on the basis of clinical laboratory tests performed at screening
• must have a normal 12-lead electrocardiogram (ECG) at screening including: normal sinus rhythm (heart rate between 45 and 100 beats per minute [bpm], extremes included); QT interval corrected for heart rate (QTc) according to Fridericia (QTcF) less than equal to (<=)470 milliseconds (ms); QRS interval less than (<)120 ms; PR interval <=220 ms
• must have a blood pressure (after the participant is supine for 5 minutes) between 90 and 140 millimeters of mercury (mmHg) systolic, inclusive, and no higher than 90 mmHg diastolic. If blood pressure is out of range, up to 2 repeated assessments are permitted
• must have a body mass index (BMI; weight in kg divided by the square of height in meters) between 18.0 and 30.0 kilogram per square meter (kg/m^2), extremes included, and a body weight not less than 50.0 kilogram (kg)

Exclusion Criteria:

• any evidence of heart block or bundle branch block
• history of liver or renal dysfunction (estimated creatinine clearance <60 milliliters per minute (mL/min) at screening, calculated by the Modification of Diet in Renal Disease [MDRD] formula12), significant cardiac, vascular, pulmonary, gastrointestinal (such as significant diarrhea, gastric stasis, or constipation that in the investigator's opinion could influence drug absorption or bioavailability), endocrine, neurologic, hematologic, rheumatologic, psychiatric, neoplastic, or metabolic disturbances
• past history of cardiac arrhythmias (example [eg], extrasystoli, tachycardia at rest), history of risk factors for Torsade de Pointes syndrome (eg, hypokalemia, family history of long QT Syndrome)
• current human immunodeficiency virus type 1 (HIV-1) or HIV-2 infection (confirmed by antibodies) at screening
• any history of clinically significant skin disease such as, but not limited to, dermatitis, eczema, drug rash, psoriasis, food allergy, and urticaria
