Positron Emission Tomography (PET) Study to Evaluate Biodistribution of [11C]-GSK2256098 in Healthy Subjects and Idiopathic Pulmonary Arterial Hypertension (PAH) Patients

Hypertension, Pulmonary Clinical Trial

Official title:
A Microdose Study to Evaluate the Biodistribution of [11C]-GSK2256098 in the Lungs and Heart of Healthy Subjects and Idiopathic Pulmonary Arterial Hypertension (PAH) Patients Using Positron Emission Tomography (PET)

Clinical Trial Summary

Pulmonary arterial hypertension (PAH) involves the narrowing of blood vessels connected to and within the lungs. Focal adhesion kinase (FAK) is a focal adhesion-associated protein kinase involved in cellular adhesion and spreading processes which leads to stiffening and thickening of blood vessels in lungs. This further increases the blood pressure within the lungs and impairs their blood flow. This study aims to demonstrate biodistribution of FAK inhibitor, GSK2256098, in cardiopulmonary sites i.e. heart and lung tissues. The uptake of 11C-radiolabelled GSK2256098 within the lung and / or heart of healthy subjects and idiopathic pulmonary arterial hypertension (iPAH) patients will be assessed using Positron Emission Tomography (PET). Based on study results the decision as to whether a follow-on phase 2 trial should be initiated to investigate the therapeutic utility of GSK2256098 in iPAH will be decided. Sufficient number of subjects will be screened (up to 30 days prior to scan) to enrol 12 healthy subjects and 12 PAH patients in the study. Enrolled subjects will receive a microdose of [11C]-GSK2256098 on a scanning day which will be followed by the follow-up visit (2-4 weeks post-last dose).
