A Study to Test the Effect of Empagliflozin in Patients Who Are in Hospital for Acute Heart Failure

This is a study in adults who are in hospital for acute heart failure. The purpose of this study is to find out whether starting to take a medicine called empagliflozin soon after first being treated in hospital helps people with acute heart failure.

Participants are in the study for about 3 months. At the beginning, participants are still in hospital. Later, they visit the hospital about 3 times and get 1 phone call. Participants are put into 2 groups by chance. One group takes 1 empagliflozin tablet a day. The other group takes

1 placebo tablet a day. Placebo tablets look like empagliflozin tablets but do not contain any medicine. Empagliflozin belongs to a class of medicines known as SGLT-2 inhibitors. It is used to treat type 2 diabetes.

During the study, the doctors check whether participants have additional heart failure events like needing to go to the hospital again because of heart failure. The participants answer questions about how their heart failure affects their life. We then compare the results between the empagliflozin and placebo groups. The doctors also regularly check the general health of the participants.

Primary outcomes

  1. Percentage of Pairwise Comparisons With Wins of Clinical Benefit, a Composite of Death, Number of Heart Failure Events (HFEs), Time to the First HFE and ≥5-point Difference in CfB in KCCQ-TSS After 90 Days of Treatment

    Time frame: Up to 90 days. For KCCQ-TSS: at baseline and at day 90.

    Clinical benefit, a composite of death, number of HFEs, time to first HFE and change from baseline (CfB) in Kansas City Cardiomyopathy Questionnaire-Total Symptom Score (KCCQ-TSS) after 90 days of treatment. All patients randomised to empagliflozin are compared to all patients randomised to placebo within strata. For any two patients, a patient will win, i.e. achieve a better clinical outcome, as determined by assessing the following criteria sequentially, stopping when an advantage for either patient is shown:

    • Death: death is worse than no death; earlier death is worse; tied if not possible to determine.
    • Number of HFEs: more HFEs is worse; tied, if same number of HFEs.
    • Time to first HFE: earlier HFE is worse; tied, if not possible to determine.
    • KCCQ-TSS CfB at Day 90: more positive CfB is better; the threshold for the difference is >= 5 for a win; tied, if difference < 5.

    The KCCQ-TSS ranges from 0 to 100, where a higher score reflects a better outcome.

    pct. = percentage

Secondary outcomes

  1. Number of Participants With Improvement of at Least 10 Points in KCCQ-TSS After 90 Days of Treatment

    Time frame: At baseline and at day 90.

    Number of participants with improvement of at least 10 points in Kansas City Cardiomyopathy Questionnaire - Total Symptom Score (KCCQ-TSS) from baseline after 90 days of treatment.

    The Kansas City Cardiomyopathy Questionnaire is a self-administered questionnaire that includes 23 items that map to 7 domains: symptom frequency, symptom burden, symptom stability, physical limitations, social limitations, quality of life and self-efficacy. The symptom frequency and symptom burden domains are merged into the total symptom score. Scores are represented on a 0-to-100-point scale, where a higher score reflects a better health status.

  2. Change From Baseline in KCCQ-TSS After 90 Days of Treatment

    Time frame: At baseline, at day 15, 30 and at day 90.

    Change from baseline in Kansas City Cardiomyopathy Questionnaire - Total Symptom Score (KCCQ-TSS).

    The Kansas City Cardiomyopathy Questionnaire is a self-administered questionnaire that includes 23 items that map to 7 domains: symptom frequency, symptom burden, symptom stability, physical limitations, social limitations, quality of life and self-efficacy. The symptom frequency and symptom burden domains are merged into the total symptom score. The score is represented on a 0-to-100-point scale, where a higher score reflects a better health status.

    Change from baseline in KCCQ-TSS at day 90 was modeled using a MMRM with visit (day 15 and day 30) as repeated measures, adjusted mean (standard error) after 90 days of treatment is reported.

  3. Change From Baseline in Log-transformed N-Terminal Pro-Brain Natriuretic Peptide (NTproBNP) Area Under the Curve (AUC) Over 30 Days of Treatment

    Time frame: From baseline to day 30.

    Change from baseline in log-transformed N-Terminal Pro-Brain Natriuretic Peptide (NTproBNP) Area under the curve (AUC) over 30 days of treatment is reported.

  4. Percentage of Days Alive and Out of Hospital (DAOH) From Study Drug Initiation Until 30 Days After Initial Hospital Discharge

    Time frame: Up to 30 days after initial hospital discharge.

    The follow-up time for DAOH analyses was defined as 30 days after initial hospital discharge, or time between initial hospital discharge and date of censoring for non-fatal events except for patients who died within the first 30 days, where 30 days was considered as the DAOH follow-up time.

    DAOH for each patient was calculated as follow-up time subtracted by the number of days in hospital during the 30 days after initial hospital discharge as well as the number of days being dead within the 30 days. Percentage DAOH was defined as DAOH divided by the DAOH follow-up time of each patient multiplied by 100.

  5. Percentage of Days Alive and Out of Hospital (DAOH) From Study Drug Initiation Until 90 Days After Randomisation

    Time frame: Up to 90 days after randomisation.

    The follow-up time for DAOH analyses was defined as 90 days after randomisation, or time between randomisation and date of censoring for non-fatal events except for patients who died within the first 90 days, where 90 days was considered as the DAOH follow-up time. DAOH for each patient was calculated as follow-up time subtracted by the number of days in hospital during the 90 days after randomisation as well as the number of days being dead within the first 90 days.

    Percentage DAOH was defined as DAOH divided by the DAOH follow-up time of each patient multiplied by 100.

  6. Incidence Rate of First Occurrence of Cardiovascular (CV) Death or Heart Failure Event (HFE) Until End of Trial Visit

    Time frame: Up to 127 days.

    Incidence rate of first occurrence of CV death or HFE until end of trial visit per 100 patient-year (pt-yrs) at risk is reported.

    Incidence rate per 100 pt-yrs = 100* number of patients with event / time at risk [years].

  7. Number of Participants With Hospitalization for Heart Failure (HHF) Until 30 Days After Initial Hospital Discharge

    Time frame: Up to 30 days after initial hospital discharge.

    Number of participants with hospitalization for heart failure (HHF) until 30 days after initial hospital discharge.

  8. Composite Renal Endpoint: Number of Participants With Chronic Dialysis, Renal Transplant, Sustained Reduction in eGFR(CKD-EPI)cr

    Time frame: Up to 90 days.

    The occurrence of the composite renal endpoint:

    • chronic dialysis (with a frequency of twice per week or more for at least 90 days), or
    • renal transplant, or
    • sustained reduction in Glomerular filtration rate estimated by the chronic kidney disease epidemiology collaboration formula with serum creatinine measurement (eGFR (CKD-EPI)cr) from baseline of ≥40%, or
    • sustained eGFR [mL/min/1.73 m2] <15 and baseline value ≥30, or
    • sustained eGFR <10 and baseline value <30; is reported by number of participants with component events. (These events may have occurred after the endpoint was already met. Combinations may not have occurred on the same day).

    Sustained was determined by 2 or more consecutive post-baseline central laboratory measurements separated by at least 30 days.

  9. Weight Change Per Mean Daily Loop Diuretic Dose After 15 Days of Treatment

    Time frame: At baseline and at day 15.

    Diuretic effect as assessed by weight change per mean daily loop diuretic dose after 15 days of treatment.

    Diuretic dose = 40 mg intravenous furosemide or 80 mg oral furosemide.
