The Effects of Ferric Derisomaltose in Patients With Acute Heart Failure and Iron Deficiency on Exercise Capacity and Quality of Life

China-Japan Friendship Hospital170 enrolled

Overview

This study will address whether the additional use of Ferric Derisomaltose on top of standard care will improve exercise capacity and quality of life in patients with acute heart failure and iron deficiency. One group of participants will receive treatment with Ferric Derisomaltose and the other group will receive normal saline 0.9% as placebo.

Acute heart failure is very common medical problem. Despite many clinical trials conducted to date in these patients, the rates of adverse outcomes remain very high. Previous comorbidities may account for it. Approximately 80% of patients hospitalized with AHF suffered from a combination of iron deficiency. A decline in exercise capacity may occur under this condition. Some research studies have suggested that giving CHF patients intravenous iron improves symptoms in the short term. It is unknown, however, whether correcting iron deficiency is beneficial to patients with AHF to improve excise capacity and whether it improves quality of life and accelerate recovery from acute duration. This study will help us answer these key questions. This is an investigator-initiated, randomised, parallel group, double-blind, placebo-controlled trial, evaluating the excise capacity improvement of using ferric derimaltose versus placebo in hospitalized patients with acute heart failure with preserved ejection fraction before discharge. Participants will be assessed daily using 6-minute walking test after IV iron injection until discharge from hospital, especially focus on the change from baseline to the 3rd day. Some questionnaire are also conducted to evaluate the self-reported status. Participants will be followed up at 2 weeks and 4 weeks. The primary and secondary endpoints will be examined in subgroups predefined by baseline variables reflecting demography, Hb level, etiology of HF, left ventricular ejection fraction, natriuretic peptide, index of iron metabolism, eGFR and others.

Time frame: Up to 3 days

Time frame: At 2 weeks, 4weeks after IV iron injection

Change From Baseline in the KCCQ Clinical Summary Score

KCCQ was a 23-item, self-administered questionnaire that measure the participant's perception of their health status, including their heart failure (HF) symptoms, impact on physical and social function and how their HF impacts the quality of life. KCCQ quantifies 7 domains: physical limitations (6 items), symptom stability (1 item), symptom frequency (4 items), symptom burden (3 items), self-efficacy (2 items), quality of life (3 items) and social limitations (4 items). Scores were generated for each domain and scaled from 0 to 100, with 0 denoting the worst and 100 the best possible status. KCCQ-clinical summary score was average of domains- physical limitation and total symptoms (average of symptom frequency and symptom burden), and transformed to a single score which ranged from 0 (worst) -100 (the best possible status), where the higher score reflected better health status.

Time frame: At 2 weeks, 4weeks after IV iron injection

Change From Baseline in the EQ-5D-5L Questionnaire Indexed Value

EQ-5D-5L: European Quality of Life-5 Dimensions-5 Levels The EQ 5D questionnaire consists of a health descriptive system for participants to self-classify and rate their health status on the day of administration. The descriptive system includes 5 items/dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression, which are coded from 1 (best state) to 5 (worst state).
