Provided are a recombinant acid α-glucosidase and pharmaceutical composition comprising a recombinant acid α-glucosidase, wherein the recombinant acid α-glucosidase is expressed in Chinese hamster ovary (CHO) cells and comprises an increased content of N-glycan units bearing one or two mannose-6-phosphate residues when compared to a content of N-glycan units bearing one or two mannose-6-phosphate residues of alglucosidase alfa. Also provided herein are methods of producing, purifying, and formulating the recombinant acid α-glucosidase or pharmaceutical composition for administration to a subject and methods of treating a disease or disorder such as Pompe disease using the recombinant acid α-glucosidase or pharmaceutical composition.

Recombinant human acid alpha-glucosidase

Provided are pharmaceutical formulations comprising a recombinant acid &#x3b1;-glucosidase, wherein the recombinant acid &#x3b1;-glucosidase is expressed in Chinese hamster ovary (CHO) cells and comprises an increased content of N-glycan units bearing one or two mannose-6-phosphate residues when compared to a content of N-glycan units bearing one or two mannose-6-phosphate residues of alglucosidase alfa; at least one buffer selected from the group consisting of a citrate, a phosphate and combinations thereof; and at least one excipient selected from the group consisting of mannitol, polysorbate 80, and combinations thereof, wherein the formulation has a pH of from about 5.0 to about 7.0. Also provided are methods of treating Pompe disease using these pharmaceutical formulations.
