Dapagliflozin After Transcatheter Aortic Valve Implantation

Pragmatic, controlled, prospective, randomized, open-label (open-label), evaluator-blind clinical trial (PROBE design) that will analyze the benefits of dapagliflozin treatment in patients with severe aortic stenosis discharged after implantation of an aortic valve prosthesis transcatheter (TAVI).

About this study

Patients discharged after TAVI, with a history of heart failure (HF) plus depressed left ventricular ejection fraction (LVEF ≤ 40%) or diabetes mellitus (DM) or glomerular filtration rate (GFR) between 25 and 75 ml/min/1.73 m2, will be randomized (1:1) before hospital discharge to receive treatment with dapagliflozin 10 mg/day or no dapagliflozin (no placebo).

Only variables available during routine clinical practice will be collected and there will be no additional tests.

The incidence of clinical events and adherence to the dapagliflozin arm will be documented at 2 time-points (3 ± 1 months and 12 months) by phone calls and review of medical records.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • SEVERE AORTIC STENOSIS UNDERWENT TAVI
  • PRIOR HEART FAILURE ADMISSION AND ONE OF THE FOLLOWING CRITERIA:
  • Left ventricular ejection fraction ≤ 40% or
  • Diabetes mellitus or
  • Estimated glomerular filtrate rate 25-75 ml/min/1.73 m2

Exclusion criteria

  • Known allergy or intolerance to SGLT2 inhibitors.
  • Concomitant therapy with sulfonylurea or SGLT2 inhibitors..
  • Systolic blood pressure < 100 mmHg or diastolic blood pressure < 50 mmHg.
  • An estimated glomerular filtration rate (GFR) below 25 ml per minute per 1.73 m2.
  • Chronic cystitis and/or recurrent urinary tract infections (2 or more in the last year)
  • Poor control of diabetes mellitus that requires SGLT-2 inhibitor prescription on discharge according to treating physician judge.
  • Any medical condition that, in the investigator´s judgment, would seriously limit life expectancy (less than one year).
  • Pregnant or breast-feeding patients
  • Patients participating in other clinical trials.

Treatment and study plan

Dapagliflozin 10 mg

Drug

Dapagliflozin 10 mg (daily oral dose)

Primary outcomes

  1. Incidence rate of the composite of all-cause mortality or worsening heart failure (HF)

    Time frame: 1 year

    All-cause mortality and worsening HF (including hospitalization for HF or an urgent visit resulting in intravenous therapy for HF).

Secondary outcomes

  1. Incidence rate all-cause mortality

    Time frame: 1 year

    All cause mortality

  2. Incidence rate of Cardiovascular death

    Time frame: 1 year

    Mortality secondary to cardiovascular cause

  3. Incidence rate of Hospitalization for Heart Failure

    Time frame: 1 year

    Heart Failure requiring hospital admission

  4. Incidence rate of Urgent Heart Failure visits

    Time frame: 1 year

    Urgent Heart Failure visit requiring intravenous therapy

  5. Incidence rate of the composite of Heart Failure hospitalization or Cardiovascular death

    Time frame: 1 year

    Composite of Heart Failure hospitalization or Cardiovascular death

  6. Total number of Heart Failure hospitalizations and Cardiovascular deaths

    Time frame: 1 year

    Total number of (first and recurrent) Heart Failure hospitalizations and Cardiovascular deaths

Other outcomes

  1. Improvement in NYHA class.

    Time frame: 1 year

    Functional class according to New York Heart Association classification

  2. Incidence of new Atrial Fibrillation

    Time frame: 1 year

    Diagnosis of new Atrial Fibrillation in patients without history of atrial fibrillation at baseline

  3. Safety endpoints

    Time frame: 1 year

    • Symptomatic hypotension. Symptomatic hypotension includes postural dizziness with systolic blood pressure < 100 mmHg, and orthostatic hypotension (defined as a decrease of >20 mmHg in systolic blood pressure or >10 mmHg in diastolic blood pressure from a supine to a standing position).
    • Major hypoglycemia. Major hypoglucemia is defined as an event where all the following criteria were confirmed by the investigator: (1) the patient experienced symptoms of severe impairment in consciousness or behaviour; (2) the patient needed external assistance; (3) intervention was needed to treat the hypoglycaemia; and (4) there was prompt recovery of acute symptoms following the intervention.
    • Ketoacidosis.
    • Genital or Urinary Infections
    • Amputation
    • Necrotizing Fasciitis of the Perineum (Fournier's Gangrene)
  4. Rate of treatment switch (crossovers)

    Time frame: 1 year

    Percentage of patients in the "dapagliflozin arm" who stop this treatment and percentage of patients in "standard care" arm who start dapagliflozin therapy
