Methods for treatment of melanoma
View Patent ↗Embodiments of the present invention are directed to methods for treatment of melanoma using an inhibitor of dihydroorotate dehydrogenase (DHODH) and to combination therapies that involve administering to a subject an inhibitor of oncogenic BRAF (e.g. BRAF(V600E)), as well as an inhibitor of dihydroorotate dehydrogenase (DHODH). Assays for identifying compounds useful for the treatment of melanoma are also provided. The methods comprise screening for compounds or agents that inhibit neural crest progenitor formation in a zebra fish model of melanoma.
1. A method for treating melanoma in a subject comprising: (i) selecting a subject with rising cancer marker protein levels or having a family history of cancer or who has had a melanoma removed surgically; and (ii) administering to a subject in need thereof a therapeutically effective amount of an inhibitor of dihydroorotate dehydrogenase (DHODH) and administering an effective amount of an inhibitor of oncogenic BRAF, wherein the inhibitor of DHODH is selected from the group consisting of:
2. The method of claim 1 , wherein the inhibitor of oncogenic BRAF is selected from the group consisting of: a small molecule, a nucleic acid RNA, a nucleic acid DNA, a protein, a peptide, and an antibody.
3. The method of claim 1 , wherein the oncogenic BRAF is BRAF(V600E).
4. The method of claim 1 , wherein the inhibitor of oncogenic BRAF is selected from the group consisting of: Sorafenib, RAF265, XL281, AZ628, GSK2118436, GDC-0879, PLX4032, and PLX4720.
5. The method of claim 1 , wherein the inhibitor of oncogenic BRAF and inhibitor of dihydroorotate dehydrogenase (DHODH) are administered to the subject sequentially or simultaneously.
6. A method for treating melanoma in a subject comprising: (i) selecting a subject with rising cancer marker protein levels or having a family history of cancer or who has had a melanoma removed surgically; and (ii) administering to a subject in need thereof a therapeutically effective amount of an inhibitor of dihydroorotate dehydrogenase (DHODH) and administering an effective amount of an inhibitor of oncogenic BRAF, wherein the inhibitor of DHODH is selected from the group consisting of:
7. The method of claim 6 , wherein the inhibitor of dihydroorotate dehydrogenase is
8. The method of claim 6 , wherein the inhibitor of dihydroorotate dehydrogenase (DHODH) is
9. The method of claim 6 , wherein the inhibitor of oncogenic BRAF is selected from the group consisting of: a small molecule, a nucleic acid RNA, a nucleic acid DNA, a protein, a peptide, and an antibody.
10. The method of claim 6 , wherein the oncogenic BRAF is BRAF(V600E).
11. The method of claim 6 , wherein the inhibitor of oncogenic BRAF is selected from the group consisting of: Sorafenib, RAF265, XL281, AZ628, GSK2118436, GDC-0879, PLX4032, and PLX4720.
12. The method of claim 6 , wherein the inhibitor of oncogenic BRAF and inhibitor of dihydroorotate dehydrogenase (DHODH) are administered to the subject sequentially or simultaneously.
