Abstract

Anti-lymphoma plant virus particles are described. The anti-lymphoma plant virus particles include a filamentous or rod-shaped plant virus particle linked to an antimitotic agent. A therapeutically effective amount of an anti-lymphoma plant virus particle can be administered to a subject to provide a method of treating lymphoma.

Claims (19)

1. An anti-lymphoma virus particle, comprising a filamentous plant virus particle linked to an antimitotic agent, wherein the filamentous plant virus particle is a member of the Alphaflexiviridae family.

2. The anti-lymphoma virus particle of claim 1 , wherein the exterior surface of the plant virus particle has been PEGylated.

3. The anti-lymphoma virus particle of claim 1 , wherein the antimitotic agent is a dolastatin.

4. The anti-lymphoma virus particle of claim 3 , wherein the dolastatin is monomethyl auristatin E (MMAE).

5. The anti-lymphoma virus particle of claim 3 , wherein the dolastatin is valine-citrulline monomethyl auristatin E (vcMMAE).

6. The anti-lymphoma virus particle of claim 1 , wherein the antimitotic agent is covalently conjugated to the exterior of the plant virus particle.

7. The anti-lymphoma virus particle of claim 1 , wherein a targeting ligand is attached to the exterior of the plant virus particle.

8. The anti-lymphoma virus particle of claim 1 , wherein the filamentous plant virus particle is Potato Virus X.

9. The anti-lymphoma virus particle of claim 8 , wherein the anti-mitotic agent is valine-citrulline monomethyl auristatin E (vcMMAE).

10. A method of treating lymphoma in a subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of an anti-lymphoma virus particle, the anti-lymphoma virus particle comprising a filamentous plant virus particle linked to an antimitotic agent, wherein the filamentous plant virus particle is a member of the Alphaflexiviridae family.

11. The method of claim 10 , wherein the lymphoma is non-Hodgkin's lymphoma.

12. The method of claim 10 , wherein the anti-lymphoma virus particle is administered together with a pharmaceutically acceptable carrier.

13. The method of claim 10 , wherein the antimitotic agent is a dolastatin.

14. The method of claim 13 , wherein the dolastatin is MMAE.

15. The method of claim 13 , wherein the dolastatin is vcMMAE.

16. The method of claim 10 , wherein the antimitotic agent is covalently conjugated to the exterior of the plant virus particle.

17. The method of claim 10 , wherein a targeting ligand is attached to the exterior of the plant virus particle.

18. The method of claim 10 , wherein the filamentous plant virus particle is Potato Virus X.

19. The method of claim 18 , wherein the anti-mitotic agent is valine-citrulline monomethyl auristatin E (vcMMAE).
