MRNA therapy for Fabry disease
View Patent ↗Disclosed herein are compositions and methods for modulating the production of a protein in a target cell. The compositions and methods disclosed herein are capable of ameliorating diseases associated with protein or enzyme deficiencies.
1. A method of treating Fabry disease, comprising administering to a human subject in need of treatment an mRNA encoding a human alpha-galactosidase (hGLA) protein such that the hGLA protein is secreted extracellularly after expression and systemically distributed, and such that serum hGLA protein level is increased for at least 72 hours as compared to the baseline serum hGLA level before treatment,
wherein the mRNA is administered via intravenous or pulmonary administration, and
wherein the Fabry disease is treated.
2. The method of claim 1 , wherein the mRNA comprises SEQ ID NO: 4.
3. The method of claim 1 , wherein the mRNA is encapsulated within a liposome.
4. The method of claim 3 , wherein the liposome comprises one or more cationic lipids, one or more non-cationic lipids, one or more cholesterol-based lipids and one or more PEG-modified lipids.
5. The method of claim 1 , wherein the mRNA comprises a non-naturally occurring nucleotide.
6. The method of claim 5 , wherein the non-naturally occurring nucleotide is pseudouridine.
7. The method of claim 1 , wherein the administering to a subject is achieved via intravenous injections.
8. The method of claim 1 , wherein the administration of mRNA results in reduction of globotrioasylceramide (Gb3) level in the human subject as compared to the Gb3 level before treatment.
