Plain English Summary
Background and study aims
There are approximately 1 million people in the UK living with heart failure. In around half these patients, the pumping function of the heart is normal. This is known as preserved ejection fraction (HFpEF). At present there are no treatments that improve survival for this type of heart failure. There is evidence to suggest that HFpEF is caused by scarring in the heart tissue. Pirfenidone is a relatively new treatment that reduces scar tissue. In patients with lung scarring it reduces the amount of scar tissue. This leads to an improvement in quality of life and outlook in these patients. The aim of this study is to assess whether pirfenidone reduces the amount of heart scarring in patients with heart failure with normal pumping function.
Who can participate?
Adults aged 40 year and over with HFpEF
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group take three capsules containing pirfenidone three times a day for one year. Those in the second group take three capsules containing a placebo (dummy drug) three times a day for one year. Participants are followed up over 11 clinic appointments over the course of one year through clinical assessments, blood testing, heart rhythm monitoring and reviewing diary cards kept by participants.
What are the possible benefits and risks of participating?
Participants benefit from having detailed assessments of their hearts undertaken and receive closer follow-up than usual with more access to heart specialists. There are minimal risks involved with participating, as pirfenidone is not associated with any serious side-effects and any side-effects are often mild and non-serious.
Where is the study run from?
1. Wythenshawe Hospital (UK)
2. Manchester Royal Infirmary (UK)
When is the study starting and how long is it expected to run for?
March 2016 to April 2020

| Scientific title | 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 |
| Study acronym | PIROUETTE |
| Study hypothesis | Pirfenidone will target the fundamental underlying pathophysiological mechanism of HFpEF i.e. ECM expansion (myocardial fibrosis), and, as a result, lead to regression of myocardial fibrosis. If true, this should lead onto improvements in cardiac structure and function, fluid status and quality of life, and thus, ultimately, translate into improved outcome. |
| Ethics approval(s) | North West – Liverpool Central NRES, 28/11/2016, ref: 16/NW/0717 |
| Condition | Specialty: Cardiovascular disease, Primary sub-specialty: Heart Failure; UKCRC code/ Disease: Cardiovascular/ Other forms of heart disease |
| Intervention | Patients will be randomised at visit 1 in a 1:1 ratio to one of two groups. Randomisation will be accomplished over the internet using web randomisation software accessed using a secure website provided via the CTRC. Block randomisation, stratified by gender (because ECM volume is higher in females than males), will be implemented, with computer generated randomisation allocations and randomly varying block sizes. Intervention group: Participants receive 3 x 267mg capsules of pirfenidone three times daily for 52 weeks. Control group: Participants receive 3 x capsules of placebo three times daily for 52 weeks. Follow up takes place at University Hospital of South Manchester, and includes 11 patient visits in total. Follow up involves clinical examination, review of medications, assessment of participant compliance, assessment of adverse events, pregnancy tests (if applicable), review of diary card, electrocardiogram, blood tests for efficacy (NT-proBNP, hsTnT), and blood tests for safety (U&Es, FBC, LFTs). |

| Phase | Phase II |
| Drug / device / biological / vaccine name(s) | Pirfenidone |
| Primary outcome measure | Absolute change in myocardial ECM volume is measured using cardiovascular magnetic resonance (CMR) scanning at baseline and 52 weeks |
| Secondary outcome measures | 1. Left ventricular (LV) volumes, mass, ejection fraction and strain is measured using cardiovascular magnetic resonance (CMR) scanning at baseline and 52 weeks 2. Absolute myocardial ECM volume is measured using cardiovascular magnetic resonance (CMR) scanning at baseline and 52 weeks 3. Absolute myocardial cell volume is measured using cardiovascular magnetic resonance (CMR) scanning at baseline and 52 weeks 4. LV diastolic function, strain and torsion, measured using echocardiography at baseline and 52 weeks 5. Left atrial volume and function is measured using cardiovascular magnetic resonance (CMR) scanning at baseline and 52 weeks 6. Myocardial energetic status (phosphocreatine to adenosine triphosphate ratio, PCr/ATP) is measured using 31Phosphorus magnetic resonance spectroscopy (31P MRS) at baseline and 52 weeks 7. Plasma levels of NT-proBNP and hsTn are measured using blood tests at baseline and 52 weeks 8. Exercise tolerance is measured using 6 minute walk distance at baseline and 52 weeks 9. Health status (quality of life), HF symptoms and physical limitations, measured using the Kansas City Cardiomyopathy Questionnaire (KCCQ) score baseline and 52 weeks 10. All-cause mortality, cardiovascular mortality and hospitalisation for heart failure is measured by SAE and SUSAR at baseline and 52 weeks 11. Safety of pirfenidone is measured by recording adverse events (AE), serious adverse events (SAE), serious adverse reactions (SAR) and suspected unexpected serious adverse reactions (SUSAR), vital signs and physical examination findings, haematological and biochemical laboratory blood tests and an electrocardiogram (ECG), measured using patient interviews, clinical examination, blood tests and ECGs, at baseline (Visit 0) and at weeks 2, 4, 8, 13, 26, 39, and 52, and, in addition, a telephone assessment at week 1 |
