Abstract

Embodiments of the current invention provide a solution to the problems associated with balancing patient toxicity with broad efficacy of cancer therapy. In particular, embodiments are directed to anti-cancer peptides that demonstrate a broad anti-cancer efficacy with a limited toxicity to normal or non-cancer cells.

Claims (6)

1 . A method for treating cancer comprising administering an effective amount of a therapeutic composition comprising a peptide selected from the group consisting of SEQ ID NO:3, SEQ ID NO:4, or SEQ ID NO:5, to a subject having cancer, wherein the cancer is breast cancer, melanoma or lung cancer, wherein the therapeutic composition is administered by injection.

2 . The method of claim 1 , further comprising administering a second anticancer therapy, wherein the second anticancer therapy is a chemotherapy, radiotherapy, immunotherapy, or anti-hormonal therapy.

3 . The method of claim 1 , further comprising administering a second anticancer therapy, wherein the second anticancer therapy is an ELANE protease.

4 . The method of claim 1 , wherein the peptide is SEQ ID NO:3.

5 . The method of claim 1 , wherein the peptide is SEQ ID NO:4.

6 . The method of claim 1 , wherein the peptide is SEQ ID NO:5.
