 STUDY CONDUCT This is an open labelled, single-dose, randomized, balanced, two-period, two-sequence, two-treatment, two-way, crossover study to investigate the bioequivalence of Test product (T) Emtricitabine, Tenofovir Disoproxil Fumarate, Levonorgestrel and Ethinyl Estradiol Tablets 200 mg/300 mg/0.15 mg/0.03 mg of Mylan Laboratories limited, India with Reference product (R=R1 + R2) R1: Truvada® (emtricitabine and tenofovir disoproxil fumarate) tablets 200 mg / 300 mg Manufactured for: Gilead Sciences Inc, Foster City, CA 94404, Made in Germany and R2: Levora® 0.15/30-28 (Levonorgestrel and Ethinylestradiol Tablets USP), 0.15 mg /0.03 mg Distributed by: Mayne Pharma Greenville, NC 27834 in healthy adult female subjects. Single-dose fed pharmacokinetics will be characterized in Fifty-four (54) healthy adult female subjects following administration of a single oral dose of either test product or reference product will be administered under fed conditions. Subjects will be housed in the clinical facility for at least 10.50 hours prior to dosing of each period and until at least 72.00 hours after investigational drug administration. Blood samples will be collected prior to dosing and for 72.00 hours after each dosing. There will be at least 14 days between dosing times for the treatment periods. Individual subjects should be dosed at approximately the same time of day in each dosing period. It is the sponsor’s intent to complete all subjects simultaneously. Thus, it is anticipated that all subjects will be completed in a single cohort within approximately 18 days following the initiation of dosing. If multiple cohorts are necessary to enroll the required number of subjects, no two cohorts can be dosed on the same day.
 Screening Procedures Each prospective subject must agree to participate in screening procedures by signing the most recent Institutional Review Board/Independent Ethics Committee approved Informed Consent Document (ICD) before any screening procedure is initiated. The Principal Investigator or Medical Sub-Investigator will review the inclusion and exclusion criteria to confirm eligibility of each subject prior to enrollment. Each subject will undergo a screening procedure for health assessment, which consists of a complete medical history, physical examination with vital signs, clinical laboratory evaluations, 12-lead ECG and Chest X-ray PA view. The physical examination findings, ECG, serum pregnancy test and the laboratory tests can be considered as valid for maximum of 21 days prior to the dosing (drug administration) in first period of the study. Chest X-ray PA view will be taken within 6 months prior to dosing (drug administration) of period-1.

The physician in charge will assess abnormal values to determine if it is clinically significant.

Clinical/Laboratory Diagnostic Tests: 

Hematology: Red blood cell count, White blood cell count, Differential white blood cell count (Neutrophils%, Lymphocytes%, Eosinophils%, Monocytes % and Basophils %), Hemoglobin estimation,  Platelet count, Blood grouping and Rh typing. Prothrombin time (PT), activated partial thromboplastin time (aPTT) and International normalized ratio (INR).

Biochemistry: Serum creatinine, Blood urea, SGOT (AST), SGPT (ALT), Serum alkaline phosphatase (ALP), Total bilirubin, Blood sugar / Plasma Glucose (Random) and Serum electrolytes (Sodium, Potassium and Chloride)

Serology: HIV (1 & 2) antibodies, Hbs Ag (Hepatitis B surface antigen) and HCV antibodies.

Urine analysis: Color, Appearance/Transparency, pH, Specific gravity, Glucose, Ketones, Bilirubin, Blood, Leucocytes, Proteins, Nitrite, Urobilinogen and Urine microscopic examination (Pus Cells, Red Blood Cells, Epithelial Cells, Casts and Crystals). 

Pregnancy test for females: Serum β-HCG pregnancy test

Additional tests: Serum Lactate, creatinine clearance

 Housing Enough subjects from the general population will be available in the clinic for Period-1 dosing in order to dose the required number of subjects. Subjects will be housed 11.00 hours prior to dosing until at least 72.00 hours after dosing.
 Bioanalytical Method A validated assay method will be employed for the analysis of Emtricitabine, tenofovir, levonorgestrel and ethinyl estradiolin plasma samples. Full validation of the method, including precision, accuracy and reproducibility will be included in the final report, along with a statement regarding the stability of frozen samples.

Repeat analysis and ISR will be performed as per respective inhouse SOPs of designated bioanalytical facility. Specific details of recovery, precision and accuracy, specificity, selectivity and sensitivity of the assay will be included in the final report.

If clinical part conducts in group, the bioanalysis will be initiated after completion of each group, but plasma concentration data will be released to PK/Stats after completion of all subjects in study. 
 Pharmacokinetic Parameter Determination  All concentration values below the lower limit of quantification (BLOQ) will be set to zero, concentration obtained as 0, <0. No Peak will be reported as Zero for all pharmacokinetic and statistical calculations. Any missing samples will be reported as ‘M’ and will not be included for pharmacokinetic and statistical analysis.

The following pharmacokinetic parameters will be computed by using Phoenix® WinNonlin® version 8.0 or higher version for Emtricitabine, Tenofovir Disoproxil Fumarate, Levonorgestrel and Ethinyl Estradiol through non compartmental method.



 

Note:

1:
For all the above computations, actual time points of the sample collection will be used in case of sample collection deviations.
2: For an acceptable Kel value, r should not be less than 0.8944 (or r2 not less than 0.80). If r is less than 0.8944, then Kel is set missing.
3: If the pre-dose value is greater than 5% of Cmax, in any period then that subject/period data will be dropped from pharmacokinetics and statistical analysis.
4: If any subject experiences emesis at or within two times the median Tmax (2 × 3.25 hours = 6.5 hours) following the drug administration in each study period, such subject data will be analyzed however data of the subject will not be included in pharmacokinetic and statistical analysis.
 Statistical Analysis of the Pharmacokinetic Parameters Statistical analysis will be performed on the data obtained from the subjects who completed the study as per IEC approved protocol using SAS version 9.4 or higher version. Descriptive statistics of all the pharmacokinetic parameters will be computed and reported for Emtricitabine, Tenofovir Disoproxil Fumarate, Levonorgestrel and Ethinyl Estradiol.

The summary statistics (for relevant pharmacokinetic parameters) will be computed and reported for both test and reference products of Emtricitabine, Tenofovir Disoproxil Fumarate, Levonorgestrel and Ethinyl Estradiol.

The ln-transformed pharmacokinetic parameters Cmax, AUC0-t and AUC0-inf of Emtricitabine, tenofovir and ethinyl estradiol and Cmax & AUC0-72 of Levonorgestrel will be subjected to Analysis of Variance (ANOVA). ANOVA model will include Sequence, Formulation, Period and Subject (Sequence) as fixed effects.

Sequence effect will be tested using Subject (Sequence) as an error term.

An F-test will be performed to determine the statistical significance of the effects involved in the model at a significance level of 5% (alpha =0.05).

All the period, Treatment and sequence effects will be tested at 5% Level of Significance.

Two one-sided test for bioequivalence and 90% confidence intervals for the ratio of least squares mean between drug formulations will be calculated, for ln-transformed data of Cmax, AUC0-t and AUC0-inf of Emtricitabine, tenofovir and ethinyl estradiol and Cmax & AUC0-72 of Levonorgestrel.

The power of a test to detect 20% difference between test and reference products will be computed and reported for Emtricitabine, Tenofovir Disoproxil Fumarate, Levonorgestrel and Ethinyl Estradiol.

Ratio of least squares means of test and reference products will be computed for ln-transformed pharmacokinetic parameters Cmax, AUC0-t and AUC0-inf.

Ratio analysis will be reported for ln-transformed pharmacokinetic parameters Cmax, AUC0-t and AUC0-inf of Emtricitabine, Tenofovir Disoproxil Fumarate, Levonorgestrel and Ethinyl Estradiol.

Intra-Subject variability will be computed for ln-transformed pharmacokinetic parameters Cmax, AUC0-t and AUC0-inf of Emtricitabine, Tenofovir Disoproxil Fumarate, Levonorgestrel and Ethinyl Estradiol.

BE criteria 

Emtricitabine, tenofovir, levonorgestrel and ethinyl estradiol: The 90% geometric confidence intervals of the ratio (T/R or A/B) of least-squares means from the ANOVA of the natural log transformed Cmax, AUC0-t and AUC0-inf should be within 80.00% to 125.00% for emtricitabine, tenofovir and ethinyl estradiol.

Levonorgestrel: The 90% geometric confidence intervals of the ratio (T/R or A/B) of least squares means from the ANOVA of the natural log transformed Cmax and AUC0-72 should be within 80.00% to 125.00% for levonorgestrel. 

Determination of biologically implausible (pharmacokinetic) outliers will be based on the observed results (concentration data; such as no detectable plasma concentration following the administration of drug) which are determined to be discordant with the rest of the subjects. Clinical and bioanalytical circumstances will be examined in an attempt to provide insight into the apparent anomalous results.

It is the sponsor’s intent to complete this study in one cohort. In the event that separate enrollments are necessary to complete the intended number of subjects, appropriate adjustments may be made to the statistical model to reflect the multi-cohort nature of the study.

a. Additional cohorts will be recruited and dosed under the following conditions:

i. Recruiting for additional enrollment(s) begin before the end of the final period of the previous enrollment;
ii. Subjects are recruited from the same population, under the same protocol requirements;
iii. dosing of additional cohorts began as soon as practical after their recruitment; and
iv. no two cohorts are dosed on the same day.  

b. Appropriate adjustments will be made to the statistical model to reflect the multi-cohort nature of the study if:

i. the number of cohorts is less than or equal to 3; and
ii. there are at least 6 subjects in each cohort
