Innovative therapies to treat and cure
hepatitis B virus (HBV) and other viral diseases

The only Active Site Polymerase Inhibitor Nucleotide (ASPIN) in Development


Combining the ASPIN, ATI-2173, with a Nucleoside Analogue (NA), such as Tenofovir (TDF) or Entecavir (ETV), in a one-pill, once-a-day regimen could completely shut down HBV polymerase activity and viral replication, potentially curing HBV infected individuals

4th generation capsid assembly
modulator (CAM) program in
development

Antios is currently developing CAMs for the treatment of HBV. Early in vivo data point to a differentiated MOA which, unlike most CAMs, may provide for a more targeted, productive clearance of the virus by the immune system. Our 4th generation CAM program, along with ATI-2173, has the potential to contribute to a functional cure for patients with HBV.
