Maxygen Inc. is a biopharmaceutical company focused on developing improved versions of protein drugs using DNA shuffling and other protein modification technologies. The company is headquartered in Redwood City, CA.

Clinical Programs

Maxygen’s clinical programs include a novel G-CSF for the treatment of chemotherapy-induced neutropenia
Neutropenia
Neutropenia, from Latin prefix neutro- and Greek suffix -πενία , is a granulocyte disorder characterized by an abnormally low number of neutrophils, the most important type of white blood cell...

, which entered clinical trials in 2006. Maxygen also has a preclinical program, MAXY-4, to develop a novel CTLA4-Ig therapeutic for the treatment of rheumatoid arthritis
Rheumatoid arthritis
Rheumatoid arthritis is a chronic, systemic inflammatory disorder that may affect many tissues and organs, but principally attacks synovial joints. The process produces an inflammatory response of the synovium secondary to hyperplasia of synovial cells, excess synovial fluid, and the development...

 and other autoimmune diseases.

Technologies

Maxygen was established to commercially exploit its proprietary recombination-based technologies for creating genetic diversity, known as its Molecular Breeding directed evolution

 platform. These technologies allow the generation of millions of variant genes and proteins, which then can be screened to identify those of potential commercial interest. This laboratory process mimics the powerful natural process of evolution. Maxygen’s work has led to numerous scientific publications and patents.

Other protein engineering
Protein engineering
Protein engineering is the process of developing useful or valuable proteins. It is a young discipline, with much research taking place into the understanding of protein folding and recognition for protein design principles....

 and protein modification technologies used by Maxygen include mutagenesis
Mutagenesis
Mutagenesis is a process by which the genetic information of an organism is changed in a stable manner, resulting in a mutation. It may occur spontaneously in nature, or as a result of exposure to mutagens. It can also be achieved experimentally using laboratory procedures...

PEGylation
PEGylation is the process of covalent attachment of polyethylene glycol polymer chains to another molecule, normally a drug or therapeutic protein. PEGylation is routinely achieved by incubation of a reactive derivative of PEG with the target macromolecule...

, glycosylation
Glycosylation
Glycosylation is the reaction in which a carbohydrate, i.e. a glycosyl donor, is attached to a hydroxyl or other functional group of another molecule . In biology glycosylation refers to the enzymatic process that attaches glycans to proteins, lipids, or other organic molecules...
