EBANGA (ansuvimab-zykl) · RIDGEBACK BIOTHERAPEUTICS

Infectious Disease Approved 2020-12-21

EBANGA (ansuvimab-zykl) is a human monoclonal antibody indicated for the treatment of infection caused by Zaire ebolavirus. The therapy is approved for use in adult and pediatric populations, including neonates born to mothers who have tested positive for the virus via RT-PCR. Its clinical application is specific to the Zaire species, as efficacy has not been established for other species of the Ebolavirus or Marburgvirus genera. Healthcare providers are advised to consider current drug susceptibility patterns when initiating treatment, as viral resistance or changes in virulence may impact the drug's effectiveness.

How EBANGA Works

Ansuvimab-zykl is a recombinant human monoclonal antibody that exerts antiviral activity against the Zaire ebolavirus. The drug specifically targets the Zaire ebolavirus glycoprotein (EBOV GP) to combat the infection. By binding to this biological target, the antibody works to inhibit the virus within the patient. The effectiveness of this mechanism is dependent on the specific viral strain, as mutations or emergence of resistance can diminish the antibody's clinical benefit.
