Assembly Biosciences, Inc. is a biotechnology company. The Company is engaged in developing approximately two platform programs, such as a class of oral therapeutics for the treatment of hepatitis B virus (HBV) infection, and a class of oral biological therapeutics, which are designed to restore health to a dysbiotic microbiome. It has discovered various core protein Allosteric Modulators (CpAMs), which are small molecules that directly target and allosterically modulate a number of Hemoglobin C functions. The Microbiome Program consists of an integrated platform that includes a strain identification and selection process, methods for strain isolation and growth under current good manufacturing practice (cGMP) conditions, and a delivery system, GEMICEL, which allows for targeted oral delivery of live biologic and conventional therapies to the lower gastrointestinal tract. The lead program from this platform, AB-M101, is in development for the treatment of C. difficile-infections.
