Intervention
As of 28/03/2013 the trial status was changed to 'stopped' as the trial was closed in January 2011 due to recruitment issues.
Please note that, as of 11/04/2008, the anticipated start and end dates of this trial were updated from 01/06/2005 and 01/04/2007 to 01/05/2008 and 31/05/2010.
This study is proposed to be a prospective, randomised double blind placebo controlled clinical trial.
