Summary for Patent: 10,369,168
Title:Administration of polynucleotide toll-like receptor 9 agonists for treating cancer
Abstract: The present disclosure relates to methods for treating cancer by intrapulmonary administration of a polynucleotide Toll-like receptor 9 agonist. The methods of the present disclosure are suitable for treating primary cancer of the lung, as well as metastatic cancer to the lung and extra pulmonary cancers thereof. Additionally, the present disclosure provides polynucleotide Toll-like receptor 9 agonists with immune stimulatory and toxicity profiles suitable for intrapulmonary administration.

Assignee: DYNAVAX TECHNOLOGIES CORPORATION (Berkeley, CA)
Application Number:16/141,828
Patent Claims:1. A method of treating cancer in a mammalian subject in need thereof, the method comprising administering to the subject by injection an effective amount a pharmaceutical composition comprising a pharmaceutically acceptable excipient and an isolated polynucleotide, wherein the polynucleotide is a 2'-deoxyribopolynucleotide consisting of the sequence of: 5'-TCGTAACGTTCGAACGTTCGANx-3' (SEQ ID NO:2), wherein x is 0, 1 or 2, each N is A, C or T, and wherein all internucleotide linkages are phosphorothioate linkages.

2. The method of claim 1, wherein the polynucleotide consists of SEQ ID NO:7, SEQ ID NO:8, or SEQ ID NO:9.

3. The method of claim 1, wherein the polynucleotide is double stranded.

4. The method of claim 1, wherein the pharmaceutical composition is administered parenterally.

5. The method of claim 1, wherein the composition is a sterile, isotonic solution.

6. The method of claim 1, wherein the composition is a dehydrated solid.

7. The method of claim 1, wherein the subject has a primary cancer selected from the group consisting of primary lung cancer and extrapulmonary cancer.

8. The method of claim 7, wherein the subject has primary lung cancer.

9. The method of claim 8, wherein the primary lung cancer is non-small-cell lung carcinoma (NSCLC) or small-cell lung carcinoma (SCLC).

10. The method of claim 8, wherein the primary lung cancer is a non-small-cell lung cancer selected from the group consisting of adenocarcinoma, squamous-cell carcinoma, and large-cell carcinoma.

11. The method of claim 7, wherein the subject has metastatic cancer to the lung.

12. The method of claim 11, wherein the metastatic cancer is a metastasis of a primary cancer selected from the group consisting of bladder cancer, breast cancer, colorectal cancer, head and neck cancer, kidney cancer, melanoma, pancreatic cancer, prostate cancer, and ovarian cancer.

13. The method of claim 11, wherein the metastatic cancer is from a cancer of unknown primary origin.

14. The method of claim 1, wherein the mammalian subject is a human.

15. The method of claim 1, further comprising administering an effective amount of a second therapeutic agent to the subject.

16. The method of claim 15, wherein the second therapeutic agent comprises a chemotherapeutic agent selected from the group consisting of actinomycin, afatinib, alectinib, asparaginase, azacitidine, azathioprine, bicalutamide, bleomycin, bortezomib, camptothecin, carboplatin, capecitabine, certinib, cisplatin, chlorambucil, crizotinib, cyclophosphamide, cytarabine, daunorubicin, docetaxel, doxifluridine, doxorubicin, erlotinib, epirubicin, epothilone, etoposide, fludarabine, flutamine, fluorouracil, gefitinib, gemcitabine, hydroxyurea, idarubicin, ifosfamide, imatinib, irinotecan, lapatinib, letrozole, mechlorethamine, mercaptopurine, methotrexate, mitomycin, mitoxantrone, octreotide, oxaliplatin, paclitaxel, pemetrexed, raltitrexed, sorafenib, sunitinib, tamoxifen, temozolomide, teniposide, tioguanine, topotecan, valrubicin, vinblastine, vincristine, vindesine, vinorelbine, and combinations thereof.

17. The method of claim 15, wherein the second therapeutic agent is an antagonist of an inhibitory immune checkpoint molecule.

18. The method of claim 17, wherein the inhibitory immune checkpoint molecule is selected from the group consisting of PD-1, PD-L1, PD-L2, CTLA-4 (CD152), LAG-3, TIM-3, TIGIT, IL-10, and TGF-beta.

19. The method of claim 17, wherein the inhibitory immune checkpoint molecule is indoleamine 2,3-dioxygenase (IDO) or tryptophan 2,3-dioxygenase (TDO).

20. The method of claim 15, wherein the second therapeutic agent is an agonist of an immune stimulatory molecule.

21. The method of claim 20, wherein the immune stimulatory molecule is selected from the group consisting of CD27, CD40, OX40 (CD134), GITR, CD137, CD28 and ICOS (CD278).

22. The method of claim 15, wherein the second therapeutic agent comprises an antibody, fragment or derivative thereof.

23. The method of claim 7, further comprising one or both of resecting the primary cancer and administering radiation therapy.
