Brief Summary

Clopidogrel is a potent anti-thrombotic drug that inhibits adenosine diphosphate (ADP)-induced platelet aggregation. This is an open-label, randomized, single dose, three-way cross over, six sequence study to investigate the relative bioavailability of two 75 milligrams (mg) clopidogrel tablet formulations (clopidogrel SB224326 test formulation 1 \[Clop F1\] and clopidogrel SB224326 test formulation 2 \[Clop F2\]) compared with the reference product (innovator) in healthy human subjects. A total of 18 healthy human subjects will be randomized, such that approximately 14 evaluable subjects complete the study. Total duration in the study for each subject will be approximately 8 weeks from screening to the follow-up visit.

You may qualify if:

• Adult subjects aged between 18 and 65 years of age inclusive, at the time of signing the informed consent.
• Healthy, non-smoker, as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring.

You may not qualify if:

• Body weight \>=50 kilograms (kg) and Body mass index (BMI) within the range 19 - 24.9 kg/square meter (m\^2) (inclusive).
• Healthy male or female subjects: MALES: Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until 24 hours after the last dose of study medication: a) Vasectomy with documentation of azoospermia. b) Male condom plus partner use of one of the contraceptive following options: Contraceptive subdermal implant, Intrauterine device or intrauterine system, Oral Contraceptive, either combined or progestogen alone, Injectable progestogen, Contraceptive vaginal ring, Percutaneous contraceptive patches, This is an all inclusive list of those methods that meet the GlaxoSmithKline (GSK) definition of highly effective: having a failure rate of less than 1% per year when used consistently and, correctly and, when applicable, in accordance with the product label. For non-product methods (e.g. male sterility), the investigator determines what is consistent and correct use. The GSK definition is based on the definition provided by International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception. FEMALES: Eligible to participate, if she is not pregnant (as confirmed by a negative serum human chorionic gonadotrophin \[hCG\] test), not lactating, and at least one of the following conditions applies: a) Non-reproductive potential defined as: Pre-menopausal females with one of the following: Documented tubal ligation, Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, Hysterectomy, Documented Bilateral Oophorectomy, Postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone \[FSH\] and estradiol levels consistent with menopause). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment. b) Reproductive potential and agrees to follow one of the options listed below in the Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) from 30 days prior to the first dose of study medication and until 24 hours after the last dose of study medication and completion of the follow-up visit.
• Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
• Innovator product contains lactose and subjects with lactose intolerance should not be included.
• Alanine aminotransferase (ALT) and bilirubin \>1.5xupper limit of normal (ULN) (isolated bilirubin \>1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin \<35%).
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
• Corrected QT interval (QTc) \> 450 milliseconds (msec) NOTES: The QTc is the QT interval corrected for heart rate according to Bazett's formula (QTcB), Fridericia's formula (QTcF), and/or another method, machine-read or manually over-read. The specific formula that will be used to determine eligibility and discontinuation for an individual subject should be determined prior to initiation of the study. In other words, several different formulae cannot be used to calculate the QTc for an individual subject and then the lowest QTc value used to include or discontinue the subject from the trial. For purposes of data analysis, QTcB, QTcF, another QT correction formula, or a composite of available values of QTc will be used.
• The following medications increase risk of bleeding: Nonsteroidal anti-inflammatory drugs (NSAIDs), warfarin, selective serotonin and serotonin norepinephrine reuptake inhibitors (SSRIs, SNRIs).
• Proton pump inhibitors: some drugs from this class have an inhibitory effect on the formation of clopidogrel active metabolite.
• History of regular alcohol consumption within 6 months of the study defined as: An average weekly intake of \>21 units for males or \>14 units for females. One unit is equivalent to 8 grams (g) of alcohol: a half-pint (\~240 milliliter \[mL\]) of beer, 1 glass (125 mL) of wine or 1 (25 mL) measure of spirits.
• Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months prior to screening.
• History of sensitivity to heparin or heparin-induced thrombocytopenia.
• History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or Medical Monitor, contraindicates their participation.
