  • The subject is a smoker (any use of tobacco or nicotine containing products) within 6 months prior to Screening
  • The subject has had treatment with prescription drugs or complementary and alternative medicines within 14 days prior to Day -1, or over-the-counter medications within 1 week prior to Day -1, with the exception of acetaminophen up to 2 g/day
  • The subject has a recent history (within the last 2 years) of drug or alcohol abuse, as defined by the investigator, or a positive drug and/or alcohol screen

Primary outcomes

  1. Pharmacokinetic (PK) variables for ethinyl estradiol and norethindrone (in plasma): AUCinf , AUClast, and Cmax

    Time frame: For Days 1 and 13: predose and 12 times post dose; for Days 2, 3, 4, 5, 14, 15, 16, and 17: one time each day

    AUC from time 0 extrapolated to infinity (AUCinf), Area under the curve (AUC) from time of dosing to last quantifiable concentration (AUClast ), and maximum concentration (Cmax)

Secondary outcomes

  1. PK variable for ethinyl estradiol and norethindrone (in plasma): tmax , t1/2 , Vz /F, and CL/F

    Time frame: For Days 1 and 13: pre-dose and 12 times post dose; for Days 2, 3, 4, 5, 14, 15, 16, and 17: one time each day

    Time to attain Cmax (tmax) , apparent terminal elimination half-life (t1/2 ), apparent volume of distribution (Vz /F), apparent body clearance after oral dosing (CL/F)

  2. PK variable for isavuconazole (in plasma): Ctrough

    Time frame: For Day 11: predose; for Days 12 and 13: predose and 12 times post dose; for Day 14 and 15: predose; and for Day 16: predose and 24 hours post dose

    trough concentration (Ctrough)

  3. PK variable for isavuconazole (in plasma): AUCtau, Cmax, and tmax

    Time frame: For Days 12 and 13: predose and 12 times post dose

    Area under the concentration-time curve during the time interval between consecutive dosing (AUCtau)

  4. Safety assessed by recording adverse events, laboratory assessments, vital signs, electrocardiograms (ECGs)

    Time frame: Day 1 through Day 24 ± 2 days
