Abstract

Provided herein are compositions comprising EV, e.g., exosome, which comprises STING agonists and methods of using such compositions for the treatment of neuroimmunological disorders. Methods of producing the compositions (e.g., EVs comprising a STING agonist) described herein are also provided.

Claims (23)

1 . A method of treating a glioblastoma multiforme in a subject in need thereof comprising administering to the subject a composition comprising an extracellular vesicle EV and a stimulator of interferon genes protein STING agonist, wherein the EV overexpresses a Scaffold X protein selected from the group consisting of: prostaglandin F2 receptor negative regulator PTGFRN, basigin BSG, immunoglobulin superfamily member 2 IGSF2, immunoglobulin superfamily member 3 IGSF3, immunoglobulin superfamily member 8 IGSF8, integrin beta-1 ITGB1, integrin alpha-4 ITGA4, 4F2 cell-surface antigen heavy chain SLC3A2, ATP transporter protein, and wherein the Scaffold X protein is a whole protein or a fragment thereof.

2 . The method of claim 1 , wherein the composition is administered intrathecally or intratumorally.

3 . The method of claim 1 , wherein the extracellular vesicle is an exosome.

4 . The method of claim 1 , wherein the STING agonist is associated with the extracellular vesicle.

5 . The method of claim 1 , wherein the Scaffold X protein is prostaglandin F2 receptor negative regulator PTGFRN or a fragment thereof.

6 . The method of claim 5 , wherein the STING agonist is linked to the PTGFRN protein or fragment thereof, optionally by a linker.

7 . The method of claim 1 , wherein the extracellular vesicle is produced by a cell that overexpresses a PTGFRN protein.

8 . The method of claim 1 , wherein the extracellular vesicle further comprises a ligand, a cytokine, or an antibody.

9 . The method of claim 8 , wherein the antibody comprises an antagonistic antibody and/or an agonistic antibody.

10 . The method of claim 1 , wherein the STING agonist is a cyclic dinucleotide or a non-cyclic dinucleotide.

11 . The method of claim 1 , wherein the STING agonist comprises a lipid-binding tag.

12 . The method of claim 1 , wherein the concentration of the STING agonist associated with the extracellular vesicle is about 0.01 μM to 100 μM.

13 . The method of claim 1 , wherein the STING agonist is selected from the group consisting of:

and a pharmaceutically acceptable salt thereof.

14 . The method of claim 13 , wherein the STING agonist is in the lumen of the extracellular vesicle and is not linked to a scaffold moiety.

15 . The method of claim 14 , wherein the composition further comprises a pharmaceutically acceptable carrier.

16 . The method of claim 1 , wherein the administering induces or modulates an immune response and/or an inflammatory response in the subject.

17 . The method of claim 1 , further comprising administering an additional therapeutic agent.

18 . The method of claim 17 , wherein the additional therapeutic agent is an antibody or antigen-binding fragment thereof or an IL-12 moiety.

19 . A kit comprising a composition which comprises an extracellular vesicle and a STING agonist and instructions for use according to the method of claim 1 .

20 . The method of claim 1 , wherein the extracellular vesicle further comprises one or more antisense oligonucleotides ASO.

21 . The method of claim 1 , wherein the EV comprises an anti-phagocytic signal on the exterior surface of the EV.

22 . The method of claim 1 , wherein the EV further comprises one or more tropism moieties that alters the distribution of the EV in a particular cell, tissue or organ.
