A method of treating a tumor in a subject in need thereof, comprising administering a therapeutically effective amount of a PD-L1 antibody to the subject; and administering a therapeutically effective amount of an IRM compound to the subject; wherein the IRM compound is N-(4-{[4-amino-2-butyl-1H-imidazo[4,5-c]quinolin-1-yl]oxy}butyl)octadecanamide, or a pharmaceutically acceptable salt thereof.
2. A method of treating a tumor in a subject in need thereof, comprising administering a therapeutically effective amount of a CTLA-4 antibody to the subject; and administering a therapeutically effective amount of an IRM compound to the subject; wherein the IRM compound is N-(4-{[4-amino-2-butyl-1H-imidazo[4,5-c]quinolin-1-yl]oxy}butyl)octadecanamide, or a pharmaceutically acceptable salt thereof.
3. A method of treating a tumor in a subject in need thereof, comprising administering a therapeutically effective amount of a PD-L1 antibody to the subject; and administering a therapeutically effective amount of a CTLA-4 antibody to the subject; and administering a therapeutically effective amount of an IRM compound to the subject; wherein the IRM compound is N-(4-{[4-amino-2-butyl-1H-imidazo[4,5-c]quinolin-1-yl]oxy}butyl)octadecanamide, or a pharmaceutically acceptable salt thereof.
4. The method of any one of claims 1 - 3 , wherein N-(4-{[4-amino-2-butyl-1H-imidazo[4,5-c]quinolin-1-yl]oxy}butyl)octadecanamide is injected directly into the tumor.
5. The method of claim 4 , wherein the tumor is a breast cancer tumor, a bladder cancer tumor, a head and neck cancer tumor, a non-small cell lung cancer tumor, a small cell lung cancer tumor, a colorectal cancer tumor, a gastrointestinal stromal tumor, a gastroesophageal carcinoma, a renal cell cancer tumor, a prostate cancer tumor, a liver cancer tumor, a colon cancer tumor, a pancreatic cancer tumor, an ovarian cancer tumor, a lymphoma, or a cutaneous T-cell lymphoma, or a melanoma.
