Bioequivalence Study of Generic Celecoxib 200 mg Capsules

A Single Dose, Randomized, Open-label, Two-way Crossover Bioequivalence Study of Generic Celecoxib 200 mg Capsules and Reference Product (CELEBREXTM) in Healthy Thai Volunteers Under Fasting Conditions

To determine and compare the rate and extent of absorption of a test formulation with that of a reference innovator formulation when given as equal labeled dose in healthy subjects under fasting conditions

Study Overview

• Status: Not yet recruiting
• Conditions: Healthy Volunteer
• Intervention / Treatment: Drug: Celecoxib 200 mg capsule

Detailed Description

This study is conducted to investigate bioequivalence information which is required to ensure therapeutic equivalence of a test product, generic celecoxib 200 mg capsule, and a reference product, CELEBREX™, as well as to be considered as one aspect of product quality.

Bioequivalence is defined as the absence of a significant difference in the rate and extent to which the active ingredient or active moiety in pharmaceutical equivalents or pharmaceutical alternatives becomes available at the site of drug action when administered at the same molar dose under similar conditions in an appropriately designed study.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult

Description

Inclusion Criteria:

• Healthy Thai male or female subjects between the ages of 18 to 55 years
• Body mass index between 18.0 to 30.0 kg/m2.
• 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-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
• Surgic ally 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.
• Have voluntarily given written informed consent (signed and dated) by the subject prior to participating in this study.

Exclusion Criteria:

• History of allergic reaction or hypersensitivity to celecoxib, sulfonamide, acetylsalicylic acid (aspirin), other NSAIDs including other cyclooxygenase-2 specific inhibitors or any other ingredient of the 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 first dose or second dose of COVID-19 vaccine within 30 days prior to check-in in each Period.
• History or evidence of cerebrovascular disease, myocardial infraction, congestive heart failure, coronary heart disease (stenosed or occluded) or paresis due to cerebrovascular accident
• History or evidence of cardiovascular bleeding, gastrointestinal bleeding, gastric or duodenal or peptic ulcer
• History or evidence of galactose intolerance, the Lapp lactase deficiency or glucosegalactose malabsorption
• History of sensitivity to heparin or heparin-induced thrombocytopenia
• History of problems with swallowing tablet or capsule
• Any condition possibly affecting drug absorption e.g. gastrectomy, enterectomy, gastritis or duodenal or gastric ulceration other than appendectomy
• History of diarrhea, vomiting or dehydration within 24 hours prior to check-in in each period
• History or evidence of drug addict or investigation with urine sample shows a positive test for drug of abuse (morphine, marijuana or methamphetamine)
• 12-lead ECG demonstrating QTc >450 msec, a QRS interval >120 msec or with an abnormality considered clinically significant at screening. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG will be repeated two more times and the average of the three QTc or QRS values will be used to determine the subject's eligibility.
• Investigation with blood sample shows positive test for HBsAg
• Abnormal liver function, ≥ 1.5 times of upper normal limit of reference range for ALT, AST or bilirubin levels at screening laboratory test
• Have sitting systolic blood pressure of less than 90 mmHg or more than 139 mmHg and diastolic blood pressure of less than 60 mmHg or more than 89 mmHg on screening or check-in day. If abnormal blood pressure detects, the measurement will be repeated two more times after take a rest for at least 5 minutes each. The last measurement value will be used to determine the subject's eligibility
• History or evidence of habitual use of tobacco or nicotine containing products and cannot abstain for at least 48 hours prior to check-in in Period 1 and continued for entire duration of the study
• History or evidence of alcoholism or harmful use of alcohol (less than 2 years) i.e., alcohol consumption of more than 14 standard drinks per week for men and 7 standard drinks per week for women (A standard drink is defined as 360 mL of beer or 150 mL of wine or 45 mL of 40% distilled spirits, such as rum, whisky, brandy etc.)

• Unwilling or unable to comply with schedule visit, treatment plan and other study procedures until end of study
