Detailed Description:

This is a randomised, double blind, placebo-controlled, two-way cross-over study to evaluate the effect of treatment with repeat dose GSK2190915, a 5-lipoxygenase-activating protein (FLAP) inhibitor, as an add-on to current therapy on the percentage of neutrophils in induced sputum in asthmatic patients with elevated sputum neutrophils. Approximately 20 subjects will be enrolled onto the study to ensure that approximately 14 evaluable subjects complete the study. All subjects will receive oral placebo and GSK2190915 100mg once daily for up to 16 days. Sputum neutrophilia will be assessed prior to treatment and on treatment. Key assessments: sputum cell counts, biomarker samples in sputum, blood and urine, and pharmacokinetics. Safety will be assessed by vital signs, electrocardiograms (ECGs), clinical laboratory safety tests and collection of adverse events (AEs).

GSK2190915 is a high affinity 5-lipoxygenase-activating protein (FLAP) inhibitor that attenuates the production of leukotrienes, through the blockage of the first committed step in the leukotriene pathway, 5-lipoxygenase (5-LO) activation. Leukotrienes are potent inflammatory molecules produced mainly by mast cells, eosinophils, monocytes/macrophage and neutrophils in response to allergic or inflammatory stimuli. As GSK2190915 reproducibly inhibits the production of leukotriene B4 (LTB4) and cysteinyl leukotrienes (cysLTs) both in vitro and in vivo it has strong potential utility in the treatment of asthma.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) < 2xUpper limit of normal (ULN); alkaline phosphatase and bilirubin ≤ 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
  • Males and females ages 18 years old and above.
  • An established clinical history of asthma in accordance with the definition by the GINA Guidelines.
  • Subjects who are stable on their current treatment for at least one month prior to first dose and for the duration of the study.
  • Persistent sputum neutrophilia in the absence of infection. Persistent is defined at being met at Screening and Visit 1 of Treatment Period 1. At least one sputum sample must show neutrophils ≥ 50%. The other sample must be > 45%.
  • A female subject is eligible to participate if she is of:

    • Non-childbearing potential defined as pre-menopausal females with a documented (medical report verification) hysterectomy or double oophorectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea or 6 months of spontaneous amenorrhea with serum Follicle Stimulating Hormone (FSH) levels > 40 mIU/mL and estradiol < 40 pg/ml (<140 pmol/L) or 6 weeks postsurgical bilateral oophorectomy with or without hysterectomy. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods specified in the protocol if they wish to continue their Hormone Replacement Therapy (HRT) during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal 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.
    • Child-bearing potential and agrees to use one of the contraception methods listed in Section 8.1 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 the follow up visit, or at least 6 days after last dose.
  • Signed and dated written informed consent is obtained from the subject
