Bioequivalence of Ketoprofen Oral Gel vs Ketoprofen Lysine Salt as Granules for Oral Solution

A Bioequivalence Study of a Test Formulation of Ketoprofen Oral Gel 25 mg Versus a Marketed Reference of Ketoprofen Lysine Salt as Granules for Oral Solution (80 mg Bipartite Sachet, Half Sachet) After Single Dose Administration Under Fed Conditions to Healthy Male and Female Subjects

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.

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Drug: Ketoprofen Lysine; Drug: Ketoprofen Oral Product

Detailed 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.

• Contraception and fertility (females only): females of child-bearing potential and with an active sexual life must be using at least one of the following reliable methods of contraception:

  1. Hormonal oral, implantable, intrauterine device [IUD], transdermal or injectable contraceptives for at least 2 months before the screening visit
  2. A non-hormonal IUD or female condom with spermicide or contraceptive sponge with spermicide or diaphragm with spermicide or cervical cap with spermicide for at least 2 months before the screening visit
  3. A male sexual partner who agrees to use a male condom with spermicide
  4. A sterile sexual partner
• Female participants of non-child-bearing potential or in post-menopausal status for at least 1 year will be admitted. For all female subjects, pregnancy test result must be negative at screening and day -1 of each study period.

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.
• Medications: medications, including over the counter (OTC) drugs [in particular ketoprofen, acetylsalicylic acid (ASA) and NSAIDs in general], herbal remedies and food supplements for 2 weeks before the start 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).
• Blood donation: blood donations for 3 months before this study.
• Drug, alcohol, caffeine, tobacco: history of drug, alcohol [> 1 drink/day for females and > 2 drinks/day for males, defined according to the USDA Dietary Guidelines 2015-2020, caffeine (more of 5 cups coffee/tea/day) or tobacco abuse (more or equal of 6 cigarettes/day).
• Drug test: positive result at the drug test at screening or day -1 of each study period.
• Alcohol test: positive alcohol breath test at day -1 of each study period.
• Diet: abnormal diets (< 1600 or > 3500 kcal/day) or substantial changes in eating habits in the 4 weeks before this study; vegetarians.
• Pregnancy (females only): positive or missing pregnancy test at screening or day -1 of each study period; pregnant or lactating women.
