Trial overview
Official title: A single dose, crossover study in healthy female subjects to assess the regional absorption and bioavailability of 100 mg GSK2190915A
Trial description: GSK2190915 is a high affinity 5-lipoxygenase-activating protein (FLAP) inhibitor that attenuates the production of leukotrienes through the blockage of the first step in the leukotriene pathway, 5-lipoxygenase (5-LO) activation. GSK2190915 inhibits the production of leukotriene B4 (LTB4) and cysteinyl leukotrienes (cysLTs).This is an open label, 4-way, 4-treatment period, non-randomised, crossover study with an interim analysis. The GSK2190915 formulations used in this study will be: a 100mg and 200mg milled tablet, a 100mg enteric-coated tablet, and a [14C] radiolabelled GSK2190915 intravenous solution.This study aims to determine the pharmacokinetics and absolute bioavailability of GSK2190915 to enable optimisation of suitable formulations to be used in clinical developmentFourteen subjects will be dosed to ensure data in 10 at the end of the clinical study. Seven of the subjects will receive an IV microtracer in addition to the other treatments.
Primary purpose:
Basic Science
Trial design:
Crossover Assignment
Masking:
None (Open Label)
Allocation:
Non-randomized
Primary outcomes:
Characterisation of the maximum concentration (Cmax), the time of Cmax (tmax) and Area Under the plasma concentration-time Curve (AUC) for intravenous and oral pharmacokinetics
Timeframe: 1 month
Determination of AUC data for all routes of administration to permit calculation of relative and absolute bioavailability where appropriate.
Timeframe: 1 month
Assessment of regiospecific bioavailability of GSK2190915A based on tmax, Cmax, and AUC to assist in subsequent oral formulation/delivery options for GSK2190915A
Timeframe: 1 month
Secondary outcomes:
To collect further information about the safety and tolerability of GSK2190915A by assessing: physical examination, safety laboratory tests, vital signs, electrocardiogram (ECG), adverse events.
Timeframe: 1 month
Quantitative and cumulative recovery of radiocarbon in urine and faeces to permit an assessment of deposition route for intravenous GSK2190915A.
Timeframe: 1 month
Collection of bile to allow profiling of metabolites of GSK2190915A.

Accepts healthy volunteers
Yes
- Healthy females as determined by an experienced study physician, based on a medical evaluation including medical history, physical examination, neurological examination, laboratory tests and electrocardiogram (ECG). A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures;
- Females must be either:
- Participation in a clinical research study involving investigational drugs or dosage forms within the previous 3 months or 4 months if new chemical entity (NCE);
- Subjects who have previously been enrolled in this study;
Inclusion and exclusion criteria
Inclusion criteria:
- Healthy females as determined by an experienced study physician, based on a medical evaluation including medical history, physical examination, neurological examination, laboratory tests and electrocardiogram (ECG). A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures;
- Females must be either:
- Of non-childbearing potential, defined as pre-menopausal females with a documented tubal ligation or hysterectomy or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MlU/ml and estradiol < 40 pg/ml (<140 pmol/L) is confirmatory]. [Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods in Section 9.4 of the protocol 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 enrollment. For most forms of HRT, at least 2-4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.]
- Of child-bearing potential and agrees to use one of the contraception methods listed in Section 9.4 of the protocol for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until 3 months after the last dose.
- Aged 18–65 years;
- Body Mass Index (BMI) of 18–35 kilogram per sqare metre (km/m2);
- Subjects must demonstrate their ability to swallow an empty size 000 capsule;
- Must be willing and able to participate in the whole study and must provide written informed consent;
- Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase and bilirubin ≤ 1.5xUpper Limit of Normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%);
- QTcB or QTcF < 450 msec
- Subjects of child-bearing potential must agree to use one of the contraception methods listed in Section 9.4 from the time of the first dose of study medication until 3 months following the last dose. -
