Clinical Trial Summary

This study is conducted to determine whether the test product (GW483100 10 mg containing montelukast sodium equivalent to 10 mg of montelukast) is bioequivalent to the reference montelukast sodium 10 mg tablets (innovator product) in healthy adult volunteers under fasting conditions. This is an open-label, balanced, randomized, single dose, two-way crossover study, enrolling 32 healthy human subjects to ensure at least 28 subjects complete the study. Each subject enrolled will participate in two treatment periods separated by a washout period of at least 7 days and no more than 14 days between dosing occasions. Total duration in the study for each subject will be approximately 7 weeks from screening to the subject's last visit.

• 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; and percutaneous contraceptive patches.

• 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 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.

• The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 90 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).

• Exposure to more than four new chemical entities within 12 months prior to the first dosing day.

• Gastrointestinal disease or with gastrointestinal surgical history which can affect the absorption of the investigational drug.

• Any symptoms with a systolic BP <95 millimeter of mercury (mmHg).
