Brief summary: Heart failure (HF) is a complex syndrome with increasing incidence and high rates of mortality and hospitalization. Although inhibitors of angiotensin converting enzyme (ACE), β-blockers and aldosterone-receptor blockers have improved the treatment of heart failure, mortality of HF remains unacceptably high.

Recently, we identified a key metabolite N-acetylneuraminic acid (Neu5Ac) increased in the plasma of patients with heart failure. Also, elevated plasma Neu5Ac, independent of other traditional risk factors, is associated with poor prognosis in patients with HF in long-term follow up. Neu5Ac levels, the most common sialic acid in mammals, generated from sialylated glycoconjugates by neuraminidase. Neu5Ac and its regulatory enzyme neuraminidase play a key role in heart failure. We found neuraminidase inhibitor could reduce Neu5Ac levels and improve heart failure in mice model, providing opportunity for a novel therapeutic strategy in HF. Neuraminidase inhibitor oseltamivir is also an old anti-influenza drug. Using oseltamivir may be a new therapeutic strategy in heart failure.

Based on above information, we designed the randomized, open-label, blank-controlled study in patients with chronic HF to receive either oseltamivir or placebo, in addition to standard HF therapy to Identify the effect of oseltamivir on serum Neu5Ac level in patients with heart failure and assess the clinic outcomes of level in patients with heart failure using oseltamivir.
