This study has been completed.
Information provided by (Responsible Party):
GlaxoSmithKline Identifier:
First received: August 9, 2007
Last updated: August 4, 2017
Last verified: August 2017
The proposed study will examine the effect of pre-treatment with inhaled GSK256066 using a lung inflammation model induced by bronchoscopic instillation of bacterial endotoxin (lipopolysaccharide, LPS) in healthy volunteers.Data from this study will be used to support GSK256066 dose selection for future studies in COPD patients.

Condition Intervention Phase
Pulmonary Disease, Chronic Obstructive Drug: GSK256066 Drug: Placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Primary Purpose: Diagnostic
Official Title: A Double Blind, Placebo Controlled, Repeat Dose Study to Compare the Effectiveness of Two Doses of GSK256066 With Placebo in Reducing Lung Inflammation Following Segmental LPS Challenge in Healthy Volunteers

Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • Absolute BAL neutrophils at 24 h post LPS exposure The total and differential cell count (absolute and percentage cell counts) in BAL at 24 h post LPS exposure [ Time Frame: 24 hours ]

Secondary Outcome Measures:
  • Vital signs, ECG, FEV1, Serum concentration of protein inflammatory biomarkers, BAL concentrations of protein inflammatory biomarkers BAL concentrations of GSK256066, Day 1,Day 7&DAY 8 [ Time Frame: Day 1,Day 7&DAY 8 ]

Enrollment: 37
Actual Study Start Date: September 27, 2007
Study Completion Date: April 23, 2008
Primary Completion Date: April 23, 2008 (Final data collection date for primary outcome measure)
