Los efectos de la terapia con hierro intravenoso en dosis bajas versus dosis altas con derisomaltosa férrica en pacientes con insuficiencia cardíaca crónica y deficiencia de hierro (IRONDOSE)

4 de noviembre de 2026 actualizado por: Jingyi Ren, China-Japan Friendship Hospital

Los efectos de la terapia con hierro intravenoso en dosis bajas versus dosis altas con derisomaltosa férrica en pacientes con insuficiencia cardíaca crónica y deficiencia de hierro: un ensayo aleatorizado, abierto y ciego con criterios de valoración (IRONDOSE)

This study will address whether intravenous (IV) iron repletion with a more intensive target will provide greater benefits in improving exercise capacity for patients with chronic heart failure and iron deficiency. One group of participants will receive a high-dose IV iron regimen with a more intensive target, and the other group will receive a low-dose IV iron regimen with a less intensive target.

Descripción general del estudio

Descripción detallada

Iron deficiency is a common and important comorbidity in heart failure. Randomized controlled trials have consistently demonstrated a beneficial effect of IV iron on exercise capacity and quality of life in iron-deficient patients with HF and reduced ejection fraction. However, these randomized controlled trials exhibit striking heterogeneity in targeting levels for maintenance strategies of IV iron repletion. Some studies (FERRIC-HF, FAIR-HF) withheld intravenous iron in cases of ferritin >800 ng/mL, hemoglobin >16.0 g/dL, or transferrin saturation (TSAT) >50%, while other studies (HEART-FID, IRONMAN) focused on targeting levels that are simply above the definition of iron deficiency. Additionally, the PIVOTAL trial showed that high-dose IV iron decreased recurrent heart failure events in patients undergoing hemodialysis compared to a lower-dose regimen. Whether functional outcomes differ between those on lower versus higher iron repletion targets among patients with heart failure remains unknown. This study will help us address this question.

This is an investigator-initiated, prospective, randomized, open-label blind endpoint study to assess the effects of high-dose IV iron repletion compared to a low-dose IV iron repletion on 12-month change in peak oxygen uptake (VO2) for patients with chronic heart failure and concomitant iron deficiency.

Patients with chronic heart failure and iron deficiency will be enrolled and randomized in a 1:1 ratio to receive a high-dose IV iron regimen and a low-dose IV iron regimen. After the initial iron repletion, ferritin concentration and TSAT were measured every three months and the results used to determine the dose of ferric derisomaltose during the follow-up period. In the high dose group, iron dosing will repeat as long as the serum ferritin was not >700ng/mL, or if TSAT was not >40%. Patients in the low dose group will receive repeat iron dosing if ferritin <100 ng/mL, or if ferritin 100-300 ng/mL and TSAT <20%, in line with criteria for iron deficiency in current guidelines.
