Abstract

The present invention provides a cancer vaccine composition for transdermal administration for cellular immunity induction, comprising (i) a WT1 peptide and/or a modified WT1 peptide; and (ii) a pharmacologically acceptable acid as a first cellular immunity induction promoter, or a pharmacologically acceptable salt thereof.

First claim

What is claimed is:

1. A method for inducing cellular immunity in a subject, which comprises transdermally administering to the subject a cancer vaccine composition comprising: (i) a WT1 peptide and/or a modified WT1 peptide; and (ii) a first cellular immunity induction promoter that is a pharmacologically acceptable acid or a pharmacologically acceptable salt thereof, wherein the pharmacologically acceptable acid is selected from the group consisting of isostearic acid, decanoic acid, myristic acid, and malic acid.

2. The method according to claim 1 , wherein the method is for treating a cancer in the subject.

3. The method according to claim 1 , wherein the cancer vaccine composition further comprises a second cellular immunity induction promoter selected from a TLR ligand, a cyclic dinucleotide, a helper peptide, an immunomodulatory small molecule drug, a cyclooxygenase inhibitor, a prostaglandin receptor antagonist, a prostaglandin receptor agonist, a TSLP production inhibitor, an adenylate cyclase inhibitor, an omega-3 fatty acid, a PPAR agonist, a dopamine receptor antagonist, a dopamine receptor agonist, a histamine receptor agonist, a histamine receptor antagonist, a serotonin receptor agonist, a serotonin receptor antagonist, a vasopressin receptor antagonist, a vasopressin receptor agonist, a muscarine receptor antagonist, a muscarine receptor agonist, an adrenalin receptor antagonist, an adrenalin receptor agonist, an angiotensin receptor agonist, a GABA receptor agonist, a thrombin receptor antagonist, a thrombin receptor agonist, an opioid receptor agonist, an ADP receptor agonist, a leukotriene receptor antagonist, a leukotriene receptor agonist, a melatonin receptor agonist, a somatostatin receptor agonist, a cannabinoid receptor agonist, a sphingosine-1 phosphate receptor agonist, a metabotropic glutamate receptor agonist, a phospholipase A2 inhibitor, a TGF-β production inhibitor, and a Th2 cytokine inhibitor, and a combination of two or more kinds of them.

4. The method according to claim 3 , wherein the second cellular immunity induction promoter is a helper peptide.

5. The method according to claim 3 , wherein the second cellular immunity induction promoter is a combination of a helper peptide and at least one substance selected from the group consisting of a TLR ligand, a cyclic dinucleotide, an immunomodulatory small molecule drug, a cyclooxygenase inhibitor, a prostaglandin receptor antagonist, a prostaglandin receptor agonist, a TSLP production inhibitor, an adenylate cyclase inhibitor, an omega-3 fatty acid, a PPAR agonist, a dopamine receptor antagonist, a dopamine receptor agonist, a histamine receptor agonist, a histamine receptor antagonist, a serotonin receptor agonist, a serotonin receptor antagonist, a vasopressin receptor antagonist, a vasopressin receptor agonist, a muscarine receptor antagonist, a muscarine receptor agonist, an adrenalin receptor antagonist, an adrenalin receptor agonist, an angiotensin receptor agonist, a GABA receptor agonist, a thrombin receptor antagonist, a thrombin receptor agonist, an opioid receptor agonist, an ADP receptor agonist, a leukotriene receptor antagonist, a leukotriene receptor agonist, a melatonin receptor agonist, a somatostatin receptor agonist, a cannabinoid receptor agonist, a sphingosine-1 phosphate receptor agonist, a metabotropic glutamate receptor agonist, a phospholipase A2 inhibitor, a TGF-β production inhibitor, and a Th2 cytokine inhibitor.

6. The method according to claim 1 , wherein the cancer vaccine composition is in the form of a cream formulation.

7. The method according to claim 1 , wherein the cancer vaccine composition is in the form of a liquid formulation.

8. The method according to claim 1 , wherein the cancer vaccine composition is administered under a mildly irritating condition.

9. The method according to claim 8 , wherein the mildly irritating condition is a condition under which transepidermal water loss (TEWL) in a model animal for skin irritation evaluation before the administration of the composition is 50 g/h·m or less.

10. The method according to claim 8 , wherein the mildly irritating condition is a condition under which the cutaneous TSLP level in a model animal for skin irritation evaluation at completion of the administration of the composition is 10000 pg/mg protein or less.

11. The method according to claim 1 , wherein the pharmacologically acceptable acid or a pharmacologically acceptable salt thereof is isostearic acid.
