Observation of Italian Patients With Heart Failure Being Treated With Dapagliflozin in Clinical Practice

AstraZeneca252 enrolled

Overview

This is an observational, non-interventional, longitudinal prospective descriptive study including participants diagnosed with Heart Failure with reduced Ejection Fraction (HFrEF) in Italy and initiated on treatment with dapagliflozin according to the approved HFrEF indication. The study is aimed at providing insights into real-world drug utilization and treatment patterns of dapagliflozin in the Italian HFrEF setting, as well as patient-reported outcomes including quality of life.

Heart failure (HF) is a significant burden for public health, affecting more than 63 million people worldwide and expected to increase as the population ages; in Italy, the estimated prevalence of HF is 1-3% and the incidence rate 2-5 cases per 1000 persons per year. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality and impacts on patients' quality of life (QoL). Dapagliflozin is the first in a novel class of glucose-lowering agents known as sodium-glucose co-transporter-2 (SGLT2) inhibitors, approved for the treatment of Heart Failure with reduced Ejection Fraction (HFrEF). As with all new drugs introduced into clinical practice, there is a strong scientific interest in producing evidence from observational studies regarding the use of dapagliflozin for the treatment of HFrEF in real-world settings with detailed clinical data on heart failure symptoms, outcomes, and health-related QoL. The overall aim of this observational study is to describe the characteristics of patients in Italy initiating dapagliflozin for the treatment of HFrEF and to provide early insights into real-world dapagliflozin treatment patterns (primary objectives) as well as patient-reported outcomes including quality of life (secondary objectives). This study is part of a multicountry study programme, including similar studies that will be conducted in other countries with similar objectives. Data from each of the individual studies may be combined in a pooled analysis.

Outcomes

Primary Outcomes

Baseline characteristics of participants

Demographic and clinical characteristics at baseline of study participants

Time frame: Baseline (enrollment)

Dapagliflozin treatment pattern

Treatment discontinuation events for dapagliflozin

Time frame: 12 months from prescription of dapagliflozin

Other medications treatment patterns

Treatment change events for other medications for heart failure and glucose-lowering medications

Time frame: 12 months from prescription of dapagliflozin

Secondary Outcomes

Patient Reported Outcome: Kansas City Cardiomyopathy Questionnaire (KCCQ)

Health-Related Quality of Life: assessment of heart failure symptoms and their impact in terms of physical limitation and quality of life, as captured by the Kansas City Cardiomyopathy Questionnaire (KCCQ). The KCCQ is scored on a scale from 0 to 100, with higher scores indicating higher quality of life.

Time frame: Baseline (enrollment), Follow-up (3, 6, 12 months after treatment initiation)

Patient Reported Outcome: Medication Adherence Report Scale (MARS-5)

Assessment of medication adherence to heart failure treatments, as captured by the five-items version of the Medication Adherence Report Scale (MARS-5). The MARS-5 is scored on a scale from 0 to 25, with higher scores indicating better treatment compliance.

Time frame: Baseline (enrollment), Follow-up (3, 6, 12 months after treatment initiation)
