  Purpose

This is a randomised, double-blind, placebo-controlled, parallel group study to determine the efficacy of twenty-seven day- repeat inhaled daily doses of GW870086X on forced expiratory volume in 1 second (FEV1). Initially there will be 3 treatment arms; placebo, 2mg GW870086X and 4mg GW870086X. After an interim analysis the trial may; continue to completion using the original doses, be terminated early, or have a fourth arm added of either 1mg GW870086X once daily or 3mg GW870086X once daily.

Detailed Description:

This is a randomised, double-blind, placebo-controlled, parallel group study to determine the efficacy of twenty-seven day- repeat inhaled doses of GW870086X on FEV1. GW870086X is a novel inhaled corticosteroid with potent glucocorticoid activity currently in development by GlaxoSmithKline (GSK) as an inhaled treatment of persistent asthma. Initially, subjects will be randomised to receive placebo, 2mg or 4mg GW870086X once daily. An interim analysis will be performed on the primary endpoint to potentially adapt the study design after approximately 45 subjects have completed dosing. Based on the results of the interim analysis, the trial may continue to completion using the original doses or an adaptation to the doses could be made. Either the 1mg GW870086X once daily arm or 3mg GW870086X once daily arm may be added, or the trial could be terminated early. After screening there will be a 4 week run in period prior to start of treatment and after will be a follow up period 1-2 weeks after last dose. Approximately 120 subjects will complete the study. Key safety assessments include; clinical laboratory tests, vital signs and collection of adverse events (AE's).

Paracetamol is an exception and will be permitted at daily doses of up to 4 g from screening to follow-up.
  • Has taken Xanthines (including theophylline, but not including caffeine), anticholinergics, cromoglycates and/or long-acting beta-2 agonists within 1 week prior to screening and is unable to abstain from them throughout the study.

  • Unwillingness or inability to follow the procedures outlined in the protocol.
  • The subject is not able to understand or comply with protocol requirements, instructions and protocol stated restrictions.
  • Vulnerable subjects.
  • Subject is mentally or legally incapacitated.
  • Urinary cotinine levels indicative of smoking or history within 6 months prior to screening.
