Abstract

Compositions, kits and methods for treating leukemia in a subject (e.g., human) include a first anti-cancer drug consisting of: Δ 12 -prostaglandin J 3 or a derivative thereof, or a prostaglandin D receptor (DP) agonist. The compositions may further include a second anti-cancer drug. Δ 12 -prostaglandin J 3 is a stable metabolite of omega-3 fatty acid, eicosapentaenoic acid (EPA), and was discovered to have anti-leukemic properties. Δ 12 -prostaglandin J 3 was shown to be highly effective in eradicating the leukemia stem cells (LSC) in two murine models of leukemia, thus increasing the survival of the mice. DP agonists were shown to induce apoptosis of human primary Acute Myelogenous Leukemia cells and may be used in compositions, kits and methods for treating leukemia in a subject. The compositions, kits and methods may be particularly useful for treating human subjects who are resistant to one or more anti-cancer drugs.

Claims (17)

1. A composition comprising a pharmaceutically acceptable carrier and a therapeutically effective amount of a first anti-cancer drug consisting of: isolated or synthesized D 12 -prostaglandin J 3 (D 12 -PGJ 3 ) for inhibiting leukemia stem cell (LSC) growth in a subject having LSCs.

2. The composition of claim 1 , further comprising a second anti-cancer drug.

3. The composition of claim 2 , wherein the second anti-cancer drug is imatinib.

4. A method of treating leukemia in a subject, comprising administering to the subject having leukemia a composition comprising a pharmaceutically acceptable carrier and at least a first anti-cancer drug consisting of: isolated or synthesized D 12 -prostaglandin J 3 in a therapeutically effective amount for inhibiting LSC growth in a subject having LSCs.

5. The method of claim 4 , wherein the LSCs are chronic myeloid leukemia stem cells or acute myeloid leukemia cells.

6. The method of claim 4 , wherein the subject is resistant to imatinib.

7. The method of claim 4 , wherein the subject is a human.

8. The method of claim 4 , wherein the composition further comprises a therapeutically effective amount of a second anti-cancer drug.

9. The method of claim 8 , wherein the second anti-cancer drug is imatinib.

10. The method of claim 4 , wherein administration of the composition induces apoptosis of the LSCs in the subject.

11. The method of claim 4 , wherein administration of the composition eliminates LSCs in the subject.

12. A kit for treating leukemia in a subject, the kit comprising:

(a) a composition comprising a pharmaceutically acceptable carrier and at least a first anti-cancer drug consisting of: isolated or synthesized D 12 -prostaglandin J 3 in a therapeutically effective amount for inducing death of LSCs in the subject;

(b) instructions for use; and

(c) packaging.

13. The kit of claim 12 , wherein the kit further comprises a therapeutically effective amount of a second anti-cancer drug.

14. The kit of claim 13 , wherein the second anti-cancer drug is imatinib.
