Assembly Biosciences, Inc. is a biotechnology company, which is engaged in the development of small molecule antiviral therapeutics. The Company’s pipeline includes two helicase-primase inhibitors (HPI) targeting recurrent genital herpes, an orally bioavailable hepatitis delta virus (HDV) entry inhibitor, a clinical-stage capsid assembly modulator (CAM) designed to disrupt the replication cycle of hepatitis B virus (HBV) at several key points with the aim of achieving finite treatment and functional cures and research programs focused on the discovery of therapeutics to treat devastating viral diseases, including a non-nucleoside polymerase inhibitor (NNPI) targeting transplant-related herpesviruses and a small molecule interferon-α (IFN-α) receptor (IFNAR) agonist targeting HBV and HDV. HPIs are antiviral agents in development for HSV-1 and HSV-2, with a clinically validated mechanism of action. Its HBV, HSV-1, and HSV-2 programs include ABI-6250, ABI-5366, and ABI-1179.
