St. Gallen, Switzerland:
- Ferinject® significantly reduced the incidence of heart failure hospitalizations in patients with iron deficiency after acute heart failure
- Results of the AFFIRM-AHF trial support the use of Ferinject® in patients after AHF with concomitant iron deficiency and with a LVEF1≤ 50%
- Simultaneously the peer-reviewed AFFIRM-AHF study results have been published in The Lancet

Vifor Pharma today presented the full results from the AFFIRM-AHF study at the 2020 American Heart Association (AHA) Scientific Sessions virtual congress. Simultaneously, results were published in the peer-reviewed medical journal The Lancet. The study evaluated the effect of Ferinject® (intravenous ferric carboxymaltose) on heart failure (HF) hospitalizations and cardiovascular (CV) mortality in iron deficient patients after hospital stabilization for acute heart failure (AHF).
The study demonstrated there were significantly fewer hospital readmissions due to HF among patients treated with Ferinject® compared to placebo. After 52 weeks, patients who received iron supplementation were 26% less likely to be re-admitted to the hospital for HF compared to placebo, after only one or two injections [RR 0.74; 95% CI 0.58-0.94; p=0.013].
“This is the first study demonstrating the benefits of iron supplementation initiated in stabilized patients hospitalized for AHF,” said Prof Piotr Ponikowski, Principle Investigatorand Head of the Department of Heart Diseases, Wroclaw Medical University in Wroclaw, Poland. “The study showed that administration of Ferinject® in stabilized AHF patients with iron deficiency significantly reduces the risk of subsequent HF hospitalizations, and highlights the need for AHF patients to be more frequently screened for iron deficiency.”
“We are delighted to have presented full data from the AFFIRM-AHF study at the American Heart Association Scientific Sessions congress. This important data strengthens the evidence previously generated in large studies such as FAIR-HF and CONFIRM-HF,” said Dr Klaus Henning Jensen, Chief Medical Officer Vifor Pharma. “Iron deficiency is a frequent, yet often unrecognized co-morbidity in heart failure, and this trial makes a significant contribution to the growing body of evidence showing the importance of detecting and managing iron deficiency in patients after heart failure.”
On September 24, 2020 Vifor Pharma announced that overall AFFIRM-AHF narrowly missed the conventional 5% statistical significance on the primary composite endpoint, but numerically reduced total CV death and HF re-hospitalization events by 21% [RR 0.79; 95% CI 0.62-1.01; p=0.059]. Ferinject® was well tolerated and without unexpected safety findings. No increase in mortality was seen and death from cardiovascular (CV) causes was similar between groups [RR 0.96; 95% CI 0.70-1.32].
The outbreak of the COVID-19 pandemic resulted in significant disruption to the healthcare systems, with a 40% reduction in HF hospitalizations in Europe between March and June 20202. HF patients are particularly at risk when suffering COVID-19. Therefore prior to study completion, COVID-19 sensitivity analysis was pre-specified which excluded subjects reporting from the date of the outbreak in each country. Adjusted for COVID-19 impact the composite endpoint was more robust and significant [RR 0.75; 95% CI 0.59-0.96; p=0.024].
Additional significant results were seen with several secondary outcomes, including treatment benefits with Ferinject® observed seen on the time to first HF hospitalization or CV death (p=0.030) and days lost due to HF hospitalizations and CV death (p=0.035). These effects were more pronounced in the pre-COVID-19 analyses.
AFFIRM-AHF is the first of three ongoing mortality and morbidity trials including FAIR-HF2 and HEART-FID to understand the full potential of Ferinject® for those suffering from heart failure and iron deficiency. The study was a randomized, double-blind placebo-controlled trial with 1,108 patients in 15 countries, designed to evaluate the effect of Ferinject® or placebo administered prior to and subsequent to discharge in patients after AHF and iron deficiency on recurrent HF hospitalizations and CV death at 52 weeks after randomization.
Iron deficiency is present in approximately 80% of patients after AHF and indicates poor prognosis. It is associated with poor quality of life and increased risk for hospitalization and mortality, regardless of the presence or absence of anemia. Hospitalization due to AHF represents a growing health care problem that is associated with a higher risk of adverse clinical outcomes and huge economic burden.
