Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Each participant will be randomly allocated to receive a single dose of each of the Test product (T), and the Reference product (R) under fasting conditions in a two-way crossover sequence:

Test product (T): Loratadine 5mg Chewable Tablets manufacture for AFT Pharmaceuticals, Australia

Administration: Following an overnight fast of at least 10 hours, subjects will be dosed one tablet at ambient temperature in an upright sitting position as per the randomization schedule. Subjects will be housed in Genecht's Clinical Pharmacology Unit where dosing and administration will take place.

The dosing and administration process as detailed below will be conducted by either the Principal Investigator or a research personnel designated by the Principal Investigator:
•Subject will wet their mouth with 20 ± 2 ml of water by swallowing, just 20 seconds before dosing.
•Subject will chew the tablet slowly and thoroughly.
•Mouth check will be performed immediately after the subject indicated that the tablet was completely chewed
•Once this is confirmed, the subject will be instructed to swallow the chewed tablet mass.
•All the subjects shall be instructed not to spit the saliva and phlegm until one hour after dosing.
•Subjects will be instructed to remain in upright posture for at least 04.00 hours post-dose except for essential reasons (e.g., use of washroom) or study procedures.

Compliance for dosing will be assessed by a thorough check of the oral cavity with a torch and disposable tongue depressor immediately after dosing.

There will be two study periods separated by a washout period of at least 14 days will be maintained between each dosing period. Subjects will be checked out after 24 hours post-dose during each study period.

Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Biostatistician will generate a randomization schedule for all study periods prior to dispensing in period I by PROC SEED procedure (such that the design is balanced over the period and sequence combination) using Statistical Analysis Software SAS® (SAS Institute Inc., USA) Version 9.4 or higher.
Study subjects will be allocated sequential numbers starting from 01. On the day of dosing, subjects will be administered either test product (T) or reference product (R) on separate occasions in each study period as per the randomization schedule.

Statistical methods / analysis
Statistical analysis will be performed using SAS® (SAS Institute Inc., USA) Version 9.4 or higher.
The observed plasma concentrations will be tabulated for each subject – product combination. Descriptive statistics including number of observations, arithmetic mean, standard deviation, range (minimum – maximum), median and coefficient of variation for untransformed data of all PK parameters, and geometric least square means and Intra CV (%) for Ln-transformed data (primary PK parameters) for test and reference products.
Concentration and PK parameters data from dropouts, withdrawn and terminated subjects will be presented in the individual listings, but will not be included in the summary statistics.
The mean and individual subject’s plasma concentrations, for Loratadine and Desloratadine versus time profiles for each product will be presented graphically as linear and semi-log plots, respectively.
The ratio of untransformed data of test and reference product for primary PK parameters will also be reported. PROC GLM will be used for the estimation of LSM differences of test and reference products on the Ln-transformed primary PK parameters for Loratadine and Desloratadine along with the computation of corresponding standard errors. The 90% CIs will be constructed for the LSM differences of Ln-transformed primary PK parameters. The antilog (or exponential) of the limits obtained from the Ln-transformed data will give the 90% CI for the ratio of geometric least square means of test and reference products.
The statistical analysis will include:
a) Two one-sided ANOVA test;
b) Ratio analysis;
c) Power analysis and
d) Acceptance criteria for bioequivalence.
Consistent with Schuirmann’s two one-sided tests procedure for bioequivalence, ANOVA at 5% level of significance will be performed on Ln-transformed PK parameters Cmax and AUC0-t to determine whether the average values for these PK measures determined after administration of the test and reference products are comparable. This will involve the calculation of 90% CI for the ratio of the averages (population geometric least square means) of the measures for test and reference products. The ANOVA model will include sequence, subjects nested within sequence, period and treatment as fixed effects factors. The significance of the sequence effect will be tested using the subjects nested within sequence as the error term. Each ANOVA testing will also include calculation of LSM, adjusted differences between formulation means and the standard error associated with these differences.
Non-parametric analysis of Tmax will be performed on untransformed data, using the Wilcoxon signed-rank test.
Geometric least square mean values will be reported for Ln-transformed primary PK parameters of Loratadine and Desloratadine on which CI is based. Ratios of means are expressed as a percentage of the LSM for the test and reference products.
The test product will be considered bioequivalent to the reference product, if 90% confidence intervals for ratio (test/reference) of geometric least square means based on Ln-transformed primary PK parameters - Cmax and AUC0-t fall within acceptable BE limits of 80.00% to 125.00% for Loratadine and Desloratadine.
