Idiopathic Pulmonary Fibrosis Clinical Trial
Official title:
Investigating the Role of the Coagulation Cascade in Idiopathic Pulmonary Fibrosis
The pathogenesis of idiopathic pulmonary fibrosis (IPF) is incompletely understood but recurrent epithelial injury occurs which evokes the coagulation cascade. Thrombin is produced as a result and is over expressed in IPF patients, so may be important in propagating disease activity. We aim to recruit patients with IPF and then complete FDG (18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose) PET (positron emission tomography) scans pre and post manipulation of the coagulation cascade to assess the role of this biological pathway in disease activity. Previous studies from our institution have demonstrated increased FDG avidity in the lungs of patients with IPF (assessed using FDG PET scans) but to date the cells and pathways responsible for this signal have not been identified and thus need further exploration.
Patients with IPF who meet all the inclusion criteria (and none of the exclusion criteria)
will be assessed and invite to participate.
They will undergo baseline assessment with lung function, 6 minute walk test and health
quality assessments.
Blood tests will assess the pro-coagulant state of these individuals. They will undergo a
baseline FDG PET scan followed by manipulation of the coagulation cascade with 24 days (+/-
3 days) dabigatran. They will then complete a second FDG PET, health quality assessments and
blood tests to demonstrate target engagement.
