Hematopoietic stem cell
Vestronidase alfa-vjbk (trade name Mepsevii), an enzyme replacement therapy which is a recombinant form of human β-glucuronidase, is approved by U.S. Food and Drug Administration for the treatment of Sly syndrome. Hematopoietic stem cell transplant (HSCT) has been used to treat other types of MPS diseases, but this is not yet available for MPS-VII. Animal experiments suggest that HSCT may be an effective treatment for MPS-VII in humans.
