About Assembly Assembly Biosciences, Inc. is a biopharmaceutical company developing novel therapies for infectious diseases and other disorders of the gastrointestinal (GI) system. Assembly's proprietary Core Protein Allosteric Modulators (CpAMs) are small molecule, oral agents for the treatment of viral infections. The company's lead program focuses on hepatitis B (HBV), which infects an estimated 350 million people worldwide and is associated with 600,000 deaths annually. CpAMs alter the HBV core protein, a unique target that is essential to the functioning of the virus. Unlike current therapies that only suppress HBV, CpAMs may have curative potential. Assembly also is developing novel microbiome-based technology for targeted oral delivery of therapeutic bacteria, complex proteins, viral antigens and small molecules to treat intractable infectious diseases of the GI tract, such as C. difficile infections.
