Trial overview
Official title: An Open-label, Randomised, Single Dose, Three-Way Crossover, Six Sequence, Pilot Study to Determine the Relative Bioavailability of Montelukast Sodium 5mg from Two Candidate Chewable Tablet Formulations of GW483100 Relative to One 5mg Chewable Tablet of Reference Montelukast Sodium in Healthy Adult Subjects Under Fasting Conditions
Trial description: This study is designed to estimate the bioavailability of montelukast from the 5 milligrams (mg) montelukast sodium (GW483100) test formulations relative to 5 mg montelukast sodium reference chewable tablets (innovator product). It is an open-label, randomized, single dose, three-way cross over, six sequence study in 18 healthy human subjects. Each subject will participate in all three treatment periods. Subjects will be randomized to one of six sequences and administered one of the three treatments A, B or C in each treatment period, where Treatment A is 5mg chewable tablet of reference 5 mg montelukast sodium reference chewable tablets (innovator product), Treatment B is test formulation 1: 5mg montelukast sodium (GW483100) chewable tablet and Treatment C is test formulation 2: 5mg montelukast sodium (GW483100) chewable tablet. The treatment periods will be separated by a washout period of 7 to 14 days. Total duration in the study for each subject will be approximately 8 weeks from screening to the follow-up visit.

Accepts healthy volunteers
Yes
- Male and females aged between 18 and 65 years of age inclusive, at the time of signing the informed consent.
- Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring.
- Alanine aminotransferase (ALT) and bilirubin >1.5 x upper 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)
Inclusion and exclusion criteria
Inclusion criteria:
- Male and females aged between 18 and 65 years of age inclusive, at the time of signing the informed consent.
- Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring.
- A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the investigator in consultation with the Medical Monitor if required, agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Body weight >= 50 kilograms (kg) and Body mass index (BMI) within the range 19 – 24.9 kilograms per square meter (kg/m^2) (inclusive).
- Male subject
- Female subject: is 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: 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 (refer to laboratory reference ranges for confirmatory levels)]. 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.
- Reproductive potential and agrees to follow one of the options listed below in the GlaxoSmithKline (GSK) Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) requirements from 30 days prior to the first dose of study medication and until [at least five terminal half-lives OR until any continuing pharmacologic effect has ended, whichever is longer] after the last dose of study medication and completion of the follow-up visit. GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in FRP This list does not apply to FRP with same sex partners, when this is their preferred and usual lifestyle or for subjects who are and will continue to be abstinent from penile-vaginal intercourse on a long term and persistent basis.

- 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 as specified in the Reporting and Analysis Plan (RAP).
