Ambrx®, Inc. is a biopharmaceutical company with a mission to deliver breakthrough protein therapeutics using an expanded genetic code. Unlike conventional conjugation techniques that create a mixture of suboptimal molecules, Ambrx technology combines site specific conjugation with proprietary linkers, payloads and pharmacokinetic extenders to create a single molecular species that is optimized for safety, efficacy and biophysical properties. We call this process Protein Medicinal Chemistry™.

Protein Medicinal Chemistry™ can optimize any protein or antibody to create potentially best-in-class therapeutics such as long-acting proteins, bi-specifics and antibody drug conjugates. The Ambrx advantage allows us to safely and effectively target cytotoxic agents or recruit effector function to tumor cells (oncology) or modulate biological pathways implicated in disease areas such as autoimmune, metabolic and cardiovascular.

At Ambrx, we are dedicated to assembling and developing an exceptional team and a novel technology to create the next generation of protein-based medicines.
