Clinical Trial Summary
The study is to compare the rate and extent of absorption of a generic formulation with that
of a reference for mulation when given as equal labeled dose. The study will be randomized,
open-label, single dose, two way crossover design with two-period, two-treatment and
two-sequence under fasting condition and at least 28 days washout period between the doses.
Description:
Title A Bioequivalence study of a randomized, open-label, single dose, two-way crossover
design with two-period, two-treatment and two-sequence of Drospirenone (3 mg) + Ethinyl
Estradiol (0.03 mg) Tablets relative to Yasmin® in healthy Thai female volunteers under
fasting condition.
Objectives The primary objective is to compare the rate and extent of absorption of a generic
formulation with that of a reference formulation when given as equal labeled dose. The
secondary objective is to evaluate the safety after oral administration of both test and
reference formulation in healthy Thai female volunteers.
Study Design Randomized, open-label, single dose, two-way crossover design with two-period,
two-treatment and two-sequence under fasting condition and at least 28 days washout period
between the doses.
Sample Size 32 Healthy Human Thai female subjects. Two extra subjects if available, may be
checked-in on the day of check in of period-I to compensate for any dropout prior to dosing
of period-I. These subjects will be dosed if there are dropouts prior to dosing in period-I.
If there are no dropouts, these subjects will be checked-out without being dosed after
completion of dosing in period-I.
Drug-Product Test-Product: Drospirenone (3 mg) + Ethinyl Estradiol (0.03 mg) Tablets
Reference-product: Yasmin® (Drospirenone (3 mg) + Ethinyl Estradiol (0.03 mg) Tablets)
Manufactured by: Bayer AG, Berlin, Germany
Administration After an overnight fasting at clinical facility of at least 10 hours, each
volunteer will receive a single dose of two tablets of Drospirenone (3 mg) + Ethinyl
Estradiol (0.03 mg) Tablets of either test or reference with 250 mL of drinking water. Each
volunteer will be allowed to drink water as desire except 1 hour before and after drug
administration. The formulation is given in a crossover fashion as per the randomization
schedule. After the administration, the subject's oral cavity will be checked by using
flashlight to confirm complete medication and fluid consumption by pharmacist.
Blood Schedule In each period, a total of 21 blood samples (approximately 10 mL each) will be
collected pre-dose (0 hour) and at 0.333, 0.667, 1.000, 1.333, 1.667, 2.000, 2.333, 2.667,
3.000, 3.500, 4.000, 4.500, 6.000, 8.000, 12.000, 16.000, 24.000, 36.000, 48.000 and 72.000
hours after study drug administration, respectively. The sample collection at 36.000, 48.000
and 72.000 hours after dosing will be on ambulatory basis (i.e. on separate visit.).
Sample Collection Blood samples will be collected through an indwelling catheter placed in a
vein using disposable syringe or through fresh venipuncture with disposable syringes and
needles. Approximately 10 mL blood sample will be collected and transferred to 2 sample
collection tubes containing K3EDTA as anticoagulant at each sampling time point. After
collection of blood samples from all the subjects at each time point, samples will be
centrifuged at 4000 rpm for 5 minutes at 4±2°C. After centrifugation, each sample collection
tube will be distributed into pre-labeled 3 cryovials, approximately 1.5 mL of plasma will be
divided equally into another 3 cryovials, 3 of each analysis will be set as original (O) and
Duplicate (D), Triplicate (T) respectively. Thereafter, Cryovials containing plasma sample
will be stored at -70±10 °C.
Analytical Method Drospirenone and Ethinyl Estradiol plasma concentration will be assayed as
per international Guidelines/In-house SOP by using a UPLC-MS/MS method.
Pharmacokinetic Parameters Drospirenone Primary pharmacokinetic parameter: Cmax, AUC0→ 72 and
secondary pharmacokinetic parameter: Tmax, T1/2, Kel will be determined from the plasma
concentration data of analytes.
Ethinyl Estradiol Primary pharmacokinetic parameter: Cmax, AUC0→t, AUC0→∞ and secondary
pharmacokinetic parameter: Tmax, T1/2, Kel, AUC % Extrap will be determined from the plasma
concentration data of analytes.
Statistical Analysis Drospirenone ANOVA, two one-sided tests for bioequivalence, for
log-transformed pharmacokinetic parameters Cmax, AUC0→72 will be performed.
Ethinyl Estradiol ANOVA, two one-sided tests for bioequivalence, for log-transformed
pharmacokinetic parameters Cmax, AUC0→t, AUC0→∞ will be performed.
Acceptance Criteria for Bioequivalence Drospirenone To be considered as bioequivalent, the
90% CI of Cmax, AUC0→72 of Drospirenone of test and reference products should be in the
interval of 80-125% for the log-transformed data Ethinyl Estradiol To be considered as
bioequivalent, the 90% CI of Cmax, AUC0→t, AUC0→∞ of Ethinyl Estradiol of test and reference
products should be in the interval of 80-125% for the log-transformed data.
