Bioequivalence Study of Apixaban 5 mg Film-coated Tablets in Healthy Thai Volunteers

A Single Dose, Randomized, Open-label, Two-period, Two-sequence Crossover Bioequivalence Study of Generic Apixaban 5 mg Film-coated Tablets and Reference Product (ELIQUIS) in Healthy Thai Volunteers Under Fasting Conditions

The goal of this bioequivalence of two formulations of generic apixaban 5 mg film-coated tablets. Single-dose under fasting conditions and pharmacokinetics will be characterized for a total of 28 healthy adult human subjects. Twenty-eight (28) subjects will be randomly assigned to receive either generic apixaban 5 mg film-coated tablets (1 x 5 mg; Test) or ELIQUISTM (1 x 5 mg; Reference) in Period 1 and after the washout period they will receive the other formulation as a crossover fashion in Period 2.

Study Overview

• Status: Not yet recruiting
• Conditions: Healthy Volunteer
• Intervention / Treatment: Drug: Apixaban 5MG

Detailed Description

Twenty-eight (28) healthy adult male and female volunteers (preferably with approximately equal numbers of each sex, if possible) 18 to 55 years will be enrolled from the general population. Healthy adult male and female volunteers will be recruited in bioequivalence study as recommended in United States (US) Food and Drug Administration (FDA), Draft Guidance on Apixaban. (11) Apixaban is a drug that can be used in any sex. By these reasons, normal healthy males and females as general population will be screened and 28 subjects will be recruited and enrolled into the study. An attempt will be made by clinical study team to recruit subjects as per requirement.

Remark: The expected ratio of male to female subjects is 1:1; however, if necessary, the ratio can be varied but not more than 25% each.

Eligibility Criteria

• Ages Eligible for Study: Adult

Inclusion Criteria:

• Healthy Thai male or female subjects between the ages of 18 to 55 years. Subject must meet age requirements at the time of signing the initial informed consent and at the dosing day in Period 1.
• Body mass index between 18.5 to 30.0 kg/m
• Normal laboratory values, including vital signs and physical examination, for all parameters in clinical laboratory tests at screening. Any abnormalities from the normal or reference range will be carefully considered clinically relevant by the physician as individual cases, documented in study files prior to enrolling the subject in this study.
• Non-smoker and non-consumer of nicotine containing products Non-smoker or non-consumer of nicotine containing products means any subject who has never smoked/consumed or stopped for at least 90 days.
• Non-pregnant woman (negative pregnancy test) and not currently breast feeding
• Female subjects abstain from either hormonal methods of contraception (including oral or transdermal contraceptives, injectable progesterone, progestin subdermal implants, progesterone-releasing IUDs, postcoital contraceptive methods) or hormone replacement therapy for at least 28 days prior to check-in in Period 1. Injectable contraceptives e.g. Depo-Provera® will be discontinued at least 6 months prior to check-in in Period 1. Subjects agree to use acceptable non-hormonal contraceptive methods such as condom, diaphragm, foams, jellies, or abstinence for at least 14 days prior to check-in in Period 1 until 7 days after the end of study in Period 2. Female subjects of non-childbearing potential must meet at least one of the following criteria prior to check-in in Period 1:
• Postmenopausal for at least 1 year or
• Surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy) at least 6 months
• Male subjects who are willing or able to use effective contraceptive e.g. condom or abstinence after check-in in Period 1 until 7 days after the end of study in Period 2.
• Able to understand and voluntarily given written informed consent (signed and dated) by the subject prior to participating in this study
• Adequate venous access in both arms for the collection of a number of samples during the study

Exclusion Criteria:

• History of hypersensitivity to dabigatran or dabigatran etexilate or to any of the excipients of product.
• History or evidence of clinically significant renal, hepatic, gastrointestinal, hematological (e.g. anemia), endocrine (e.g. hyper-/hypothyroid, diabetes), pulmonary or respiratory (e.g. asthma), cardiovascular (e.g. hyper-/hypotension), psychiatric (e.g. depression), neurologic (e.g. convulsant), allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at time of dosing) or any significant ongoing chronic medical illness.
• Have high risk for coronavirus infection based on risk assessment questionnaire or diagnosed as confirmed case of COVID-19
• History about administration of COVID-19 vaccine within 30 days prior to check-in in each Period
• Have eGFR (CKD-EPI) < 50 mL/min/1.73 m2 based on serum creatinine results, at the screening laboratory test or during enrollment.
• History or evidence of haemorrhagic manifestations, patients with a bleeding diathesis or patients with spontaneous or pharmacological impairment of haemostasis
