Bioequivalence of Nomegestrol Acetate (NOMAC) and Estradiol (E2) in Commercial Versus Phase 3 Pivotal Clinical Batches of NOMAC-E2 Tablets (P06328)

For the contraceptive application a film-coated tablet has been developed which combines nomegestrol acetate (NOMAC) with estradiol (E2). This was an open-label, randomized, single-dose, four-way, replicate, cross-over study design conducted in 2 parallel parts at two sites, one site per study part. The primary objective of Part 1 was to assess the bioequivalence of NOMAC and E2 of the drug product manufactured using the commercial process ("commercial batch") versus the Phase 3 drug product ("Batch A"). The primary objective of Part 2 was to assess bioequivalence of NOMAC and E2 of the drug product manufactured using the commercial process ("commercial batch") versus the Phase 3 drug product ("Batch B").

Treatment and study plan

Commercial NOMAC-E2

Drug

1 x 2.5 mg NOMAC/1.5 mg E2 fixed dose combination commercial tablet orally in the morning on Day 1 for all periods

Other names: SCH 900121

Phase 3 NOMAC-E2 "Batch A"

Drug

1 x 2.5 mg NOMAC/1.5 mg E2 fixed dose combination tablet from the Phase 3 clinical trial program ("Batch A") orally in the morning on Day 1 for all periods

Other names: SCH900121

Phase 3 NOMAC-E2 "Batch B"

Drug

1 x 2.5 mg NOMAC/1.5 mg E2 fixed dose combination tablet from the Phase 3 clinical trial program ("Batch B") orally in the morning on Day 1 for all periods

Other names: SCH 900121

Primary outcomes

  1. Maximum Observed Plasma Concentration of NOMAC (Cmax of NOMAC)

    Time frame: 0 hours to time of maximum observed plasma concentration of NOMAC (tmax of NOMAC) (blood samples were collected for NOMAC evaluation up to 144 hours postdose)

    Bioequivalence for NOMAC and E2 were tested on the primary PK parameters: Cmax, AUC(infinity), and AUClast for NOMAC; and baseline adjusted AUC72 and Cmax for E2.

    Blood samples for pharmacokinetic (PK) evaluation of NOMAC were collected at predose (0 hour) and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24, 48, 72, 96, and 144 hours postdose Day 1.

  2. Baseline Corrected Maximum Observed Serum Concentration of E2 (Cmax of E2)

    Time frame: 0 hours to time of maximum observed serum concentration of E2 (tmax of E2) (blood samples were collected for E2 evaluation up to 96 hours postdose)

    Bioequivalence for NOMAC and E2 were tested on the primary PK parameters: Cmax, AUC(infinity), and AUClast for NOMAC; and baseline adjusted AUC72 and Cmax for E2.

    Blood samples for PK evaluation of E2 were collected predose (-1, -0.5, and 0 hour) and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours postdose Day 1; multiple predose samples were needed to correct for endogenous levels.

  3. Area Under the Concentration-time Curve From Time 0 to the Time of the Last Measurable Sample (AUC Last) and Area Under the Concentration-time Curve From Time 0 to Infinity (AUC Infinity) for NOMAC

    Time frame: 0 hours to time of the last measurable sample (blood samples were collected for NOMAC evaluation up to 144 hours postdose)

    Bioequivalence for NOMAC and E2 were tested on the primary PK parameters: Cmax, AUC(infinity), and AUClast for NOMAC; and baseline adjusted AUC72 and Cmax for E2.

    AUClast is the AUC from time 0 to the time of the final quantifiable sample.

    AUC infinity is the AUC from time 0 to infinity.

    Blood samples for PK evaluation of NOMAC were collected at predose (0 hour) and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24, 48, 72, 96, and 144 hours postdose Day 1.

  4. Baseline Corrected Area Under the Concentration-time Curve From Time 0 to 72 Hours (AUC72) for E2

    Time frame: 0 hours to 72 hours

    Bioequivalence for NOMAC and E2 were tested on the primary PK parameters: Cmax, AUC(infinity), and AUClast for NOMAC; and baseline adjusted AUC72 and Cmax for E2.

    AUC72 is the AUC from time 0 to 72 hours.

    Blood samples for PK evaluation of E2 were collected predose (-1, -0.5, and 0 hour) and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours postdose Day 1; multiple predose samples were needed to correct for endogenous levels.

Secondary outcomes

  1. Tmax of NOMAC

    Time frame: 0 hours to tmax of NOMAC (blood samples were collected for NOMAC evaluation up to 144 hours postdose)

  2. Tmax of E2

    Time frame: 0 hours to tmax of E2 (blood samples were collected for E2 evaluation up to 96 hours postdose)

  3. Terminal Phase Half Life (t1/2) of NOMAC

    Time frame: 0 hours to t1/2 (blood samples were collected for NOMAC evaluation up to 144 hours postdose)

  4. t1/2 of E2

    Time frame: 0 hours to t1/2 (blood samples were collected for E2 evaluation up to 96 hours postdose)

  5. Clearance (Calculated for NOMAC Only)

    Time frame: blood samples were collected for NOMAC evaluation up to 144 hours postdose

  6. Volume of Distribution (Calculated for NOMAC Only)

    Time frame: blood samples were collected for NOMAC evaluation up to 144 hours postdose
