FDA Approves Ridgeback Ebanga Ebolavirus Treatment
FDA has approved Ridgeback Biotherapeutics’ Ebanga (ansuvimab-zykl), a human monoclonal antibody, to treat Zaire ebolavirus infection in adults and children. An agency notice says Ebanga blocks binding of the virus to the cell receptor, preventing its entry into the cell.
The agency says that Zaire ebolavirus is one of four Ebolavirus species that can cause a potentially fatal human disease.
Ebanga’s safety and efficacy were evaluated in the multi-center PALM trial in which 174 participants with confirmed Ebolavirus infection received Ebanga intravenously as a single 50 mg/kg infusion and 168 participants received an investigational control. The primary endpoint was 28-day mortality. Of the 174 patients who received Ebanga, 35.1% died after 28 days, compared to 49.4% of those who received the investigational control.
