NCT ID: NCT01245426

Last Updated: 2016-12-01

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 136 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2010-12-31
• Study Completion Date: 2011-08-31

Brief Summary

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).

Eligibility Criteria

Inclusion Criteria

• Male or female between 18 and 65 years
• A female subject is eligible to participate if she is of: Non-childbearing potential. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment.
• Male subjects must agree to use one of the protocol contraception methods.
• Body weight, men ≥ 50 kg, women ≥ 45 kg and BMI within the range 18.5 - 29.0 kg/m2 (inclusive).
• Documented history of bronchial asthma, first diagnosed at least 6 months prior to the screening visit and currently being treated only with intermittent short-acting beta-2 agonist therapy
• Severity of Disease: A best FEV1 of 60%-85% of the predicted normal value during the Visit 1 screening period.
• No history of smoking within 6 months of the start of the study and with a total pack year history of ≤10 pack years
• Capable of giving written informed consent
• Single QTcB or QTcF < 450 msec; or QTc < 480 msec in subjects with Bundle Branch Block.
• AST and ALT < 2xULN; alkaline phosphatase and bilirubin ≤ 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).

Exclusion Criteria

• A positive test for Hepatitis B or Hepatitis C antibody.
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities
• The subject has a positive pre-study drug/alcohol screen unless a positive can be explained by the patients' medication.
• Past or present disease, which as judged by the investigator, may affect the outcome of this study.

• History of life-threatening asthma, defined as an asthma episode that required intubation and/or was associated with hypercapnoea, respiratory arrest and/or hypoxic seizures.
• Administration of oral, injectable or dermal steroids within 8 weeks of screening.
• Exacerbation of asthma within 4 weeks prior to the first dose of study medication.
• Respiratory Infection that is not resolved within the 4 weeks before screening and led to a change in asthma management, or in the opinion of the Investigator is expected to affect the subjects asthma status or the subjects ability to participate in the study.
