Low-dose rivaroxaban in heart failure: COMMANDER HF

ESC Congress News 2018 - Munich, Germany

In a Hot Line session yesterday, Professor Faiez Zannad (Centre Hospitalier Universitaire de Nancy, Nancy, France) presented results from the COMMANDER HF trial investigating whether low-dose rivaroxaban reduces the morbidity and mortality associated with vascular and haemostatic dysfunction in patients with heart failure (HF).(1)

Prof. Zannad points out that, “Rivaroxaban is approved at higher doses to treat conditions such as atrial fibrillation (AF) and venous thromboembolism, but in COMMANDER HF, patients were randomised to a lower dose (2.5 mg twice daily) or matching placebo, in combination with antiplatelet therapy and standard therapy for HF.” The primary efficacy endpoint was a composite of all-cause mortality, myocardial infarction (MI) and stroke, and the primary safety endpoint was a composite of fatal bleeding or bleeding into a critical space with potential for permanent disability. Regarding patient baseline characteristics, the median age was 66 years, the majority of patients were men (77%) and median LVEF was 34%.

Prof. Zannad explains the main findings, “During a median follow-up of 21.1 months, we found no significant difference in the primary efficacy outcome, which occurred in 25.0% of patients in the rivaroxaban group compared with 26.2% on placebo (hazard ratio [HR] 0.94, 95% confidence interval [CI] 0.84–1.05, p=0.27). There were no differences between groups in all-cause mortality or nonfatal MI but there was a significantly lower rate of nonfatal stroke with rivaroxaban vs placebo (HR 0.66, 95% CI 0.47–0.95, p=0.023).”

“We found no significant difference in the primary efficacy outcome.”

No significant difference in the principal safety outcome was observed, which occurred in 0.7% of patients in the rivaroxaban group and 0.9% in the placebo group (HR 0.80, 95% CI 0.43–1.49, p=0.48); however, patients taking rivaroxaban had a significantly higher risk of International Society on Thrombosis and Haemostasis-defined major bleeding compared with those on placebo (HR 1.68, 95% CI 1.18–2.39, p=0.003).

Prof. Zannad concludes, “The most likely reason rivaroxaban failed to improve the primary efficacy outcome is that thrombin-mediated events are not the major driver of cardiovascular events in patients with recent HF hospitalisation.
