Bioequivalence Study of Baricitinib From Barcimiant 4 mg Film Coated Tablets (Horus Pharma, Egypt) and Olumiant 4 mg Film Coated Tablets (Eli Lilly Nederland B.V., The Netherlands)

Comparative randomized, single dose, three-way, three-sequence, two treatment, partial replicate, crossover, open-label study to determine the bioequivalence of Baricitinib from Barcimiant 4 mg Film Coated Tablets (Horus Pharma, Egypt) and Olumiant 4 mg Film Coated Tablets (Eli Lilly Nederland B.V., The Netherlands)

Primary Pharmacokinetic Parameters: Cmax, AUC0→t and AUC0→∞ Secondary Pharmacokinetic Parameters: Ke, tmax and t1/2e. ANOVA using 5% significance level for transformed (with the 90% confidence intervals) and untransformed data of Cmax, AUC0→t and AUC0→∞ and for untransformed data of Ke, tmax and t1/2e.

The confidence intervals of logarithmically transformed Test/Reference ratios for Cmax, AUC0→t and AUC0→∞ to be within 80.00-125.00%.

A comprehensive final report will be issued upon the completion of the study.
