Safety of HMA-CD20 in Patients With HFrEF (ICFEr-RITU2)

Phase II Clinical Trial Testing the Safety of a Humanized Monoclonal Antibody Anti-CD20 in Patients With Heart Failure With Reduced Ejection Fraction

The study is a phase II single-centered, single group, prospective clinical trial to evaluate the safety of HMA-CD20 doses among stable patients with class III/IV according to the NYHA classification with HFrEF receiving standard of care therapy. The index qualifying HFrEF must have EF < 40% based on echocardiographic or cardiac MRI techniques, heart failure class III/IV according to the NYHA classification,aged 40-60 years, being diagnosed less than 12 months before enrollment of study, following the standard heart failure treatment regimen.

Intervention / Treatment

EXPERIMENTAL: Interventional Group; For this trial, HMA-CD20 will be given as an intravenous infusion of 1000 mg I.V twice in a month separating them by fourteen days starting at the baseline visit. The dose for both HMA-CD20 dosages willbe identical at the screening visit after the participant's eligibility has been established, and it will remain thesame for both infusions. The standard dose for HMA-CD20 is 1,000 mg per intravenous infusion on day 1 and day 15.

Drug: Rituximab; Rituximab will be studied in patients with HFrEF, and verify the patients safety.
