About this trial
Cognitive impairment (CI) is highly prevalent in patients with heart failure with reduced ejection fraction (HFrEF), which has significant implications for disease management, quality of life and clinical outcomes. Currently, there are no specific treatments for CI aside from the current standard of care therapy for HF, making this a high unmet medical need. Impaired cerebral autoregulation is a proposed mechanistic factor that leads to cerebral hypoperfusion, ischemic damage and the development for CI. Preclinical data indicates that restoring CFTR-protein expression normalizes cerebral microvascular function and cerebral blood flow (CBF) in models of HF. The purpose of this study is to investigate whether CFTR-targeting therapy enhances cerebral perfusion and cognitive function in heart failure patients using the CFTR-corrector Lumacaftor.
Eligibility criteria
Qualifiers
Provide written informed consent
Aged 18 years or older with stable heart failure NYHA class II-III, with reduced cardiac output and an EF of <40% on optimal goal directed medical therapy as per CCS Guidelines and the AHA/ACC/HFSA Guidelines for the Management of Heart Failure
No hospital admissions for inpatient care in 3 months prior to study
CBF at screening of ≤45 mL/100g/min
Disqualifiers
Participants with symptomatic HF who have non-MRI compatible cardiac implantable electronic devices (CIEDs), such as a cardiac defibrillator or pacemaker, or in whom this is required within 3 months of the study
Those requiring coronary revascularisation in 6 months following the study
Participants with cystic fibrosis (CF) or any other condition that may require use of CFTR modulating agents
Participants using antiallergics (e.g., montelukast), antibiotics (e.g., clarithromycin), anticoagulants (e.g., warfarin), anticonvulsants (e.g., carbamazepine), antidepressants (e.g., citalopram), antifungals (e.g., fluconazole), anti-mycobacterials (e.g., rifabutin), barbituates, benzodiazepines (e.g., midazolam), immunosuppressants (e.g., cyclosporine), proton pump inhibitors (e.g., esomeprazole) within 30 days of trial start
