Envision a world without HBV
Innovative therapies
Antios is developing transformative treatments for hepatitis B virus (HBV).
HBV remains a formidable challenge
Even after decades of ongoing effort, the current standard of care is unable to provide a functional cure for HBV infection1
Our lead therapeutic candidate, ATI-2173, is the only active site polymerase inhibitor nucleotide (ASPIN) in development
Antios has been exploring combination therapy with other complementary drug classes to shut down viral replication and take the first step toward a potential cure for hepatitis B.2,3
ASPIN MOA
ATI-2173 leverages a novel mechanism of action (MOA) to disrupt polymerase activity and shut down viral replication.1
Antios is currently developing ATI-1428 for
the treatment of HBV1

Our CAMs have the potential to synergize with ATI-2173 and target different stages of the HBV life cycle1
