About

This is a single dose, open-label, randomised, two period, two-way cross-over, two stage bioequivalenve study with the aim to investigate the bioequivalence between a new formulation of ketoprofen 25 mg versus OKI 80 mg granules for oral solution (half sachet), after single dose administration in two consecutive periods to healthy voluteers under fed conditions.

Full description

The present bioequivalence phase I study has been designed to compare the bioavailability and the concentration-time profile of the new immediate release oral gel formulation of ketoprofen 25 mg with a marketed reference of ketoprofen lysine salt (KLS) as granules for oral solution (80 mg bipartite sachet, half sachet containing 40 mg of KLS, corresponding to 25 mg as ketoprofen), when administered in fed conditions to healthy male and female subjects. The study has been designed under fed conditions since the leaflet of the reference.

A two-stage design has been selected for the present study considering the margin of uncertainty existing over the sample size estimate in order to accomplish the primary study objectives in terms of ketoprofen rate (Cmax) and extent (AUC0-t) of absorption of the two formulations.

Enrollment: 36 patients

Exclusion criteria

• Electrocardiogram (ECG 12-leads, supine position): clinically significant abnormalities.
• Physical findings: clinically significant abnormal physical findings which could interfere with the objectives of the study.
• Laboratory analyses: clinically significant abnormal laboratory values indicative of physical illness.
• Allergy: ascertained or presumptive hypersensitivity to the active principles (ketoprofen) and/or formulations' ingredients; history of hypersensitivity to drugs (in particular to NSAIDs) or allergic reactions in general, which the Investigator considers may affect the outcome of the study.
• Diseases: significant history of renal, hepatic, gastrointestinal, cardiovascular, respiratory (including asthma), skin, haematological, endocrine or neurological and autoimmune diseases that may interfere with the aim of the study.

Paracetamol will be allowed as therapeutic counter-measure for adverse events (AEs) according to the Investigator's opinion. Hormonal contraceptives and hormone replacement therapies for females will be allowed.
• Investigative drug studies: participation in the evaluation of any investigational product for 3 months before this study. The 3-month interval is calculated as the time between the first calendar day of the month that follows the last visit of the previous study and the first day of the present study (date of the informed consent signature).
