A Randomised, Double-blind, Placebo-controlled, Phase 2 Study of the Efficacy and Safety of Pirfenidone in Patients With Heart Failure and Preserved Left Ventricular Ejection Fraction

2016-10-14 02:08:22 | BioPortfolio


This randomised, double-blind, placebo-controlled, phase 2 study aims to evaluate the efficacy and safety of the anti-fibrotic drug pirfenidone in the treatment of patients with heart failure and preserved left ventricular ejection fraction (HFpEF). Participants will be randomised to receive either pirfenidone or placebo, for a period of 12 months.


Myocardial fibrosis is a key pathological mechanism in HFpEF. Pirfenidone is an anti-fibrotic medication licensed for the treatment of idiopathic lung fibrosis, for which it reduces lung function decline, improves progression free survival and reduces all cause mortality. In pre-clinical models, pirfenidone attenuates profibrotic pathways and is associated with regression of myocardial fibrosis. Previous studies in HFpEF populations using anti-fibrotic medications, such as angiotensin-converting enzyme (ACE) inhibitors, angiotensin-II receptor blockers and aldosterone antagonists have shown some benefit in reaching secondary end-points but do not reduce mortality. HFpEF is the final result of a number of specific underlying pathological mechanisms, and targeted treatment of these mechanisms has been cited as the future approach to further clinical trials. The investigators aim to select a population of HFpEF patients with high levels of interstitial myocardial fibrosis as measured on cardiac MRI (CMR), and randomise participants to receive pirfenidone or placebo. The primary outcome is to detect a significant reduction in myocardial fibrosis as measured on CMR after 12 months of intervention.

Medical and Biotech [MESH] Definitions

Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE).

A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

A state of elevated cardiac output due to conditions of either increased hemodynamic demand or reduced cardiac oxygen output. These conditions may include ANEMIA; ARTERIOVENOUS FISTULA; THYROTOXICOSIS; PREGNANCY; EXERCISE; FEVER; and ANOXIA. In time, compensatory changes of the heart can lead to pathological form of high cardiac output and eventual HEART FAILURE.

Tumors in any part of the heart. They include primary cardiac tumors and metastatic tumors to the heart. Their interference with normal cardiac functions can cause a wide variety of symptoms including HEART FAILURE; CARDIAC ARRHYTHMIAS; or EMBOLISM.

Heart failure caused by abnormal myocardial contraction during SYSTOLE leading to defective cardiac emptying.
