- Brief Summary
Recent clinical trials have proven the cardiovascular benefits of new medications for patients with heart failure with reduced ejection fraction (HFrEF), especially sodium-glucose co-transporter 2 (SGLT2) inhibitors. There are no existing randomized clinical trials evaluating the efficacy and safety of dapagliflozin (nor any other SGLT2-inhibitor) to limit cardiac remodeling in patients with acute myocardial infarction (AMI) and left ventricular (LV) dysfunction.
Preventing cardiac remodeling, an established predictor of subsequent heart failure (HF) and cardiovascular death, is likely to translate into benefit in reducing clinical events in post-MI patients.
- Detailed Description
DAPA-PROTECTOR is a prospective multicenter, randomized, double blind, phase III trial.
Patients with confirmed AMI (e.g., STEMI or very high-risk NSTEMI) with LV dysfunction (LVEF≤45%) after completion of percutaneous coronary intervention (PCI) will be assessed for eligibility. Patients will be randomized (in a 1:1 ratio) to receive dapagliflozin (10mg once day) or placebo for 6 months, on top of standard of care as recommended in current guidelines. Treatment will be prescribed as soon as possible after admission The first TTE (TTE-1) will be performed to confirm inclusion criteria (LVEF≤45%). Four visits are scheduled: at baseline and randomization (Visit D0), at discharge from the CICU (Visit 2) at Month 3 ±2 weeks (Visit 3), and at Month 6 (+ 4 weeks) (Visit 4). After randomization, Visit 2 and Visit 3 will be scheduled to check the tolerance of the drug. In addition, a phone call will be done to the patient to make sure he's not taking any Dapagliflozin (or equivalent as Empagliflozin) in addition to experimental treatment. Finally, the last visit (Visit 4) will be scheduled to collect clinical follow-up and to perform a TTE (TTE-2). Efficacy criteria will be assessed from randomization to Month 6 by TTE. All TTE results will be anonymized and centralized at a Corelab with assessment by independent cardiologists unaware of the patient treatment group.
