Abstract
The present invention relates to fumarate polymersomes. The polymersomes are capable of targeting immune cells and then hydrolysing to release the immunomodulatory compound fumarate. The polymersomes can thus be used methods for the treatment of prevention of diseases, including immune diseases such as multiple sclerosis and psoriasis.
Claims12
A polymersome that comprises an amphiphilic block copolymer comprising a hydrophilic block and a hydrophobic block, wherein:
- (a) the hydrophilic block comprises a phosphorylcholine polymer;
- and
- (b) the hydrophobic block comprises a fumarate polymer;
- further wherein the polymersome is configured to release fumarate as an active agent at a desired site of action by in situ hydrolysis.
A pharmaceutical composition comprising:
- a plurality of polymersomes;
- and one or more pharmaceutically acceptable excipients or diluents;
- wherein each polymersome of the plurality of polymersomes comprises an amphiphilic block copolymer comprising a hydrophilic block and a hydrophobic block, wherein:
- (a) the hydrophilic block comprises a phosphorylcholine polymer;
- and
- (b) the hydrophobic block comprises a fumarate polymer;
- further wherein each polymersome of the plurality of polymersomes is configured to release fumarate as an active agent at a desired site of action by in situ hydrolysis.
A method comprising administering a therapeutically effective amount of a polymersome to a subject, wherein the polymersome comprises an amphiphilic block copolymer comprising a hydrophilic block and a hydrophobic block, wherein:
- (a) the hydrophilic block comprises a phosphorylcholine polymer;
- and
- (b) the hydrophobic block comprises a fumarate polymer;
- further wherein the method comprises the release of fumarate as an active agent from the polymersome at a desired site of action by in situ hydrolysis.
