| Oral Contraceptive Tablet + JNJ-42847922 | EXPERIMENTAL | All participants will receive one oral contraceptive (OC) tablet containing ethinyl estradiol (EE) 0.03 milligram (mg) and levonorgestrel (LN) 0.15 mg once daily on Days 1 to 21 for both cycle 1 and cycle 2. In addition, in cycle 2, participants will receive 40 mg of JNJ-42847922 once daily on Days 14 to 21. Participants will not be given OC tablet on Days 22 to 28 during cycle 1 and cycle 2 (tablet-free period). |
| Ethinylestradiol/Norethindrone | EXPERIMENTAL | During the first oral contraceptive (OC) cycle participants will receive ethinylestradiol/norethindrone 35 microgram (mcg)/1 milligram (mg) alone once daily (qd) for 21 days on Days 1 to 21 (Cycle I: lead-in). During the second OC cycle (from Day 29 to Day 56), participants will receive ethinylestradiol/norethindrone 35 mcg/1 mg alone qd for 21 days on Days 29 to 49 (Cycle II: OC alone, reference). During the third OC cycle (from Day 57 to Day 84), participants will receive ethinylestradiol/norethindrone 35 mcg/1 mg qd for 21 days on Days 57 to 77 and in addition JNJ-63623872, 600 mg twice daily (bid) for 5 days on Days 73 to 77 (Cycle III: OC plus JNJ-63623872, test). |

Ethinylestradiol is an investigational small molecule being studied in healthy female volunteers as part of drug interaction trials. It is used in these trials as a component of oral contraceptives to evaluate how other investigational drugs affect its pharmacokinetics. It is not approved for any indication and remains in clinical development.
Ethinylestradiol is being developed by Johnson & Johnson, traded on the New York Stock Exchange under the ticker JNJ. The company is conducting Phase 1 clinical trials to study the drug's interactions with other investigational compounds in healthy female participants.
Ethinylestradiol is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. Two Phase 1 trials have been completed, with no active trials currently ongoing, and the drug is being studied only in healthy volunteers.
Ethinylestradiol has been studied in two completed Phase 1 trials. NCT02652650 evaluated its interaction with JNJ-63623872 in 18 healthy women in Belgium. NCT03249402 evaluated its interaction with JNJ-42847922 in 24 healthy women in Belgium. Both trials were uncontrolled and not blinded.
Ethinylestradiol is a synthetic estrogen used in oral contraceptives. It works by binding to estrogen receptors, which helps regulate the menstrual cycle and prevent ovulation. In the studied trials, it was administered as part of combination oral contraceptives to assess potential drug interactions.
Ethinylestradiol is the same compound as ethinyl estradiol, a synthetic form of estrogen used in oral contraceptives. In clinical trial records, it is sometimes spelled as ethinyl estradiol, but both names refer to the identical drug substance.
