Outcome Measures
Primary Outcome Measures
- Area-under-the-curve (AUC) of rifampin and itraconzaole on Annovera (segesterone acetate and ethinyl estradiol) [Day 1 for itraconazole cohort, Day 11 for rifampin cohort]
AUC for 24 hours for segesterone acetate and ethinyl estradiol
- Maximum concentration (Cmax) of rifampin and itraconzaole on Annovera (segesterone acetate and ethinyl estradiol) [Day 1 for itraconazole cohort, Day 11 for rifampin cohort]
Cmax for segesterone acetate and ethinyl estradiol
Secondary Outcome Measures
- Safety - Number of Participants with Adverse Events [Screening through 14 days following Annovera removal]
Serious adverse events (SAEs) and adverse events (AEs)
- Safety - Vital signs - systolic and diastolic blood pressure [Through study completion, an average of 4 months]
Measurements of systolic and diastolic blood pressure will be compared from Screening to end of treatment/end of study
- Safety - Vital signs - pulse [Through study completion, an average of 4 months]
Measurements of pulse will be compared from Screening to end of treatment/end of study
- Tolerability -Discontinuation rates [Through study completion, an average of 4 months]
Participant rates of discontinuation due to AEs will provide information regarding tolerability

-
intra-uterine contraceptive device without hormone release system placed at least 28 days prior to the start of the first treatment cycle;
-

-
- If not sterile and sexually active with a sterile male partner, the partner is at least 6 months post-vasectomy.
-
- Willing to abstain from Tylenol/acetaminophen use and from consuming grapefruit or grapefruit juice from 7 days pre-dose until after the last PK blood sample collection of each period.
-
- Willing to abstain from alcohol from 24 hours pre-dose until after the last PK blood sample collection of each period.
-
- Signed informed consent prior to entry into the trial.

Exclusion Criteria
Contraindications for enrollment will be the same as those for use of CHCs and additional criteria important to the objectives of this study and include:
-
- Known hypersensitivity to estrogens or progestins.
-
- Pregnant, trying to become pregnant, or breastfeeding.
-
- Known hypersensitivity to silicone rubber.
-
- Undiagnosed abnormal vaginal bleeding.
-
- Undiagnosed vaginal discharge, vaginal lesions or abnormalities. Participants diagnosed at screening with a chlamydia or gonococcus infection may be included in the trial following treatment; partner treatment is also recommended. Investigators should make a determination if participants are at high risk for reinfection, eg, multiple sex partners, untreated partner, and whether such participants can be included.
-
- History of pelvic inflammatory disease since the participant's last pregnancy.
-
- History of toxic shock syndrome.

-
- Carcinoma of the endometrium or other known or suspected estrogen-dependent neoplasia.

-
cc. Use of liver enzyme inducers on a regular basis and sex steroid hormone treatments (see Section 8.3 for list of exclusionary medications).
-
dd. Use of monthly injectable contraceptives, unless suspended 2 months before initiation of the treatment. Use of Depo-Provera® [depot medroxyprogesterone acetate] unless suspended 9 months before treatment.
