Ferric derisomaltose versus no IV iron for people with symptomatic chronic heart failure and iron deficiency

A Phase III, Randomized, Open-label, Blinded Endpoint, Comparative Trial of Ferric Derisomaltose Versus no Intravenous Iron in Iron-deficient Subjects With Symptomatic Chronic Heart Failure

Phase 3 Interventional Pharmacosmos A/S · NCT06929806

This trial will test whether giving IV ferric derisomaltose to people with symptomatic chronic heart failure and low iron lowers the chance of hospitalization or death from heart or blood vessel disease.

What this trial studies

This Phase 3, randomized study assigns participants 50/50 to receive either IV ferric derisomaltose or no IV iron while all continue standard heart failure care. The main outcome is the number of participants hospitalized or dying from cardiovascular causes. Participants will attend 4–5 in-person visits and have up to 7 phone/video contacts for follow-up. The sponsor listed is Pharmacosmos A/S and the listed site is a private clinic in Pasadena, California.

Who should consider this trial

Good fit: Adults aged 18 and older with symptomatic chronic heart failure (NYHA II–IV), left ventricular ejection fraction ≤45%, and laboratory evidence of iron deficiency who have not received IV or IM iron in the past 6 months are the intended participants.

Not a fit: People without iron deficiency, those with LVEF >45%, pregnant or nursing women, those planning imminent cardiac procedures, or those recently treated with IV/IM iron are unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, the treatment could reduce cardiovascular hospitalizations and deaths and improve outcomes for people with heart failure and iron deficiency.

How similar studies have performed: Other IV iron formulations have shown symptom and hospitalization benefits in heart failure with iron deficiency, so the approach has supporting evidence though ferric derisomaltose itself has fewer large outcome trials.
