HFrEF Polypill in Sri Lanka RCT

2026年8月25日 更新者:Anubha Agarwal、Washington University School of Medicine

Heart Failure With Reduced Ejection Fraction Polypill in Sri Lanka: A Multi-Center Type I Hybrid Randomized Controlled Trial

The aim of this study is to evaluate, in adults with HFrEF in Sri Lanka, the effects of an HFrEF polypill implementation strategy on the composite rate of cardiovascular disease mortality and recurrent heart failure hospitalizations, compared with usual care over a minimum of 12-months of follow-up.

Primary outcome of the study:

1) Composite rate of cardiovascular disease mortality and recurrent heart failure hospitalizations over study duration

Secondary outcomes of the study:

  1. Rate of cardiovascular disease mortality over study duration
  2. Rate of recurrent heart failure hospitalizations over the study duration
  3. Rate of all-cause mortality over the study duration
  4. Change in left ventricular ejection fraction at 12-months and end of study assessed by transthoracic echocardiogram
  5. Change in BNP levels at 12 months and end of study
  6. Change in overall and domain specific health-related quality of life at 12-months and end of study assessed by a translated validated version of the Kansas City Cardiomyopathy Questionnaire (KCCQ-23)
  7. Change in physician-reported New York Heart Association class at 12-months and end of study
  8. Adherence to guideline-directed medical therapy assessed by pill count and MARS-5 questionnaire at baseline, 1-, 6-, 12-months, and end of study. Persistence assessed as continuation of assigned therapy at each follow-up visit. Dose optimization assessed as proportion achieving target doses (Strength 3 of the polypill, or comparable individual GDMT doses in the comparator arm) at 6-, 12-months, and end of study.

Safety outcomes:

  1. Proportion of participants with serious adverse events according to Good Clinical Practice guidelines over study duration
  2. Proportion of participants with adverse events of special interest over study duration
  3. Proportion of participants with adverse events leading to HF drug discontinuation over study duration
  4. Mean change from baseline to 12-months and end of study in serum potassium (mEq/L)
  5. Mean change from baseline to 12-months and end of study in serum creatinine (mg/dL)

Participants will be randomly assigned 1:1 stratified by sex and site to one of two groups, intervention (experimental arm) or usual care (control arm). The intervention group will be given four guideline-recommended medications for heart failure with reduced ejection fraction, combined in one over-encapsulated pill, with three dose strength options. Both groups will be observed over a minimum of 12-months of follow-up to assess key outcomes.

調査の概要

詳細な説明

The study intervention will be a heart failure with reduced ejection fraction (HFrEF) polypill consisting of bisoprolol (beta-blocker), losartan (ARB), eplerenone (MRA), and dapagliflozin (SGLT2i) manufactured using the over-encapsulation method and will undergo extensive stability testing to ensure quality. There will be 3 strengths of the HFrEF polypill available to facilitate initiation with low dose to prioritize clinical tolerability and laboratory safety and titration to higher doses of the HFrEF polypill. The dose of initiation and titration will be at the investigator's discretion. The HFrEF polypill will be delivered by licensed physicians responsible for managing heart failure at participating sites. Eligible providers must have formal medical qualifications in Sri Lanka and be actively involved in the care of patients with HFrEF. This includes cardiologists, internists, or general practitioners with experience in heart failure management. All participating physicians will receive standardized training on the study protocol including titration protocol, HFrEF polypill composition, and guidance for patient counseling prior to trial initiation to ensure consistent and accurate delivery of the intervention. Participants receiving the HFrEF polypill will also receive a "HFrEF polypill card" that delineates the drugs and doses included in the HFrEF polypill combination and contact information for the local study team in case of hospitalization at another facility.

HFrEF polypill combinations by strength:

HFrEF polypill strength 1: bisoprolol 2.5 mg + losartan 25 mg + eplerenone 25 mg + dapagliflozin 10 mg HFrEF polypill strength 2: bisoprolol 5 mg + losartan 50 mg + eplerenone 25 mg + dapagliflozin 10 mg HFrEF polypill strength 3: bisoprolol 10 mg + losartan 100 + eplerenone 50 mg + dapagliflozin 10 mg

Participants in the comparator control group will receive usual care from their healthcare providers. Providers will be encouraged to treat all participants according to international and local clinical practice guidelines. Participants in the intervention group will be provided with the HFrEF polypill by the study, and participants in the control group will be provided HFrEF medications through the pharmacy at the public hospital site(s) in Sri Lanka where they are generally free of cost.

実験的:HFrEF Polypill

The study intervention is a HFrEF polypill consisting of bisoprolol (beta-blocker), losartan (ARB), eplerenone (MRA), and dapagliflozin (SGLT2i) manufactured using the over-encapsulation method. There will be 3 strengths of the HFrEF polypill available:

Strength 1: bisoprolol 2.5 mg + losartan 25 mg + eplerenone 25 mg + dapagliflozin 10 mg Strength 2: bisoprolol 5 mg + losartan 50 mg + eplerenone 25 mg + dapagliflozin 10 mg Strength 3: bisoprolol 10 mg + losartan 100 mg + eplerenone 50 mg + dapagliflozin 10 mg

Every intervention participant will be established on the highest tolerated strength of the HFrEF polypill, with Strength 3 as the target dose. Following initiation at the strength matched to the participant's background guideline-directed medical therapy, the polypill strength will be advanced by one level at each scheduled study visit aligned with the initiation and titration protocol.
