  • Any clinically significant history of breakthrough bleeding
  • Using tobacco or other nicotine containing products within 12 months prior to the first study-specific COC-cycle intake
  • History of alcohol abuse or drug addiction
  • Positive drug and alcohol screen at screening and (each) admission to the clinical research center
  • Average intake of more than 24 units of alcohol per week

Treatment and study plan

AQX-1125

Drug

Investigational Drug

Combined oral contraceptive

Drug

COC containing 100 ug Levonorgestrel (LNG) and 20 ug Ethinyl Estradiol (EE)

Primary outcomes

  1. Maximum observed plasma concentration (Cmax) of COC taken with AQX-1125

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the effect of multiple doses of 200 mg AQX-1125 once daily (qd) on the pharmacokinetics (PK) of the COC

  2. Time to attain maximum observed plasma concentration (tmax) of COC taken with AQX-1125

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the effect of multiple doses of 200 mg AQX-1125 once daily (qd) on the pharmacokinetics (PK) of the COC

  3. Area under the plasma concentration-time curve up to 24 hours (AUC0-24) of COC taken with AQX-1125

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the effect of multiple doses of 200 mg AQX-1125 once daily (qd) on the pharmacokinetics (PK) of the COC

  4. Terminal elimination rate constant (Kel) of COC taken with AQX-1125

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the effect of multiple doses of 200 mg AQX-1125 once daily (qd) on the pharmacokinetics (PK) of the COC

  5. Terminal elimination half-life (t1/2) of COC taken with AQX-1125

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the effect of multiple doses of 200 mg AQX-1125 once daily (qd) on the pharmacokinetics (PK) of the COC

Secondary outcomes

  1. Safety and tolerability of AQX-1125 200 mg qd administered with the COC

    Time frame: 16 weeks (from start of pre-treatment cycle 1 to completion of treatment period B)

    Safety and tolerability will be assessed by the severity and frequency of adverse events, which will include any abnormal clinically significant vital signs, laboratory tests, electrocardiogram and physical examination findings

  2. Maximum observed plasma concentration (Cmax) of AQX-1125 taken with COC

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the PK of 200 mg AQX-1125 qd when given together with the COC

  3. Time to attain maximum observed plasma concentration (tmax) of AQX-1125 taken with COC

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the PK of 200 mg AQX-1125 qd when given together with the COC

  4. Area under the plasma concentration-time curve up to 24 hours (AUC0-24) of AQX-1125 taken with COC

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the PK of 200 mg AQX-1125 qd when given together with the COC

  5. Terminal elimination rate constant (Kel) of AQX-1125 taken with COC

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the PK of 200 mg AQX-1125 qd when given together with the COC

  6. Terminal elimination half-life (t1/2) of AQX-1125 taken with COC

    Time frame: 8 Weeks (from start of treatment period A to completion of treatment period B)

    To assess the PK of 200 mg AQX-1125 qd when given together with the COC
