Patent number: 9315790Abstract: The present invention provides a pharmaceutical composition comprising a protein having ?-galactosidase activity for treating Fabry disease, which causes no allergic side effect, which is highly stable in blood (plasma) and which can readily be taken up by a cell of an affected organ. The pharmaceutical composition for treating Fabry disease of the invention comprises, for example, a protein which acquires an ?-galactosidase activity through alteration of the structure of the active site of wild-type human ?-N-acetylgalactosaminidase.Type: GrantFiled: September 13, 2013Date of Patent: April 19, 2016Assignees: TOKYO METROPOLITAN INSTITUTE OF MEDICAL SCIENCE, ALTIF LABORATORIES INC.Inventors: Hitoshi Sakuraba, Youichi Tajima, Ikuo Kawashima, Seiichi Aikawa, Fumiko Aikawa
