Summary for Patent: 10,111,900

Title:	.beta.-glucan methods and compositions that affect the tumor microenvironment
Abstract:	This disclosure relates to the combination of soluble .beta.-glucan and immune suppression-relieving agents that affect the tumor microenvironment. Soluble .beta.-glucan promotes an immunostimulatory environment, which allows enhanced effectiveness of anti-angiogenics, checkpoint inhibitors including non-tumor targeting antibodies.

Assignee:	BIOTHERA, INC. (Eagan, MN)
Application Number:	15/386,781
Patent Claims:	1. A method of treating a subject having cancer, the method comprising administering soluble .beta.(1,6)-[poly-(1,3)-D-glucopyranosyl]-poly-.beta.(1,3)-D-glucopyranos- e and an anti-PD-1 antibody. 2. The method according to claim 1, wherein the cancer is melanoma, renal cell carcinoma, or lung cancer. 3. The method according to claim 1, wherein the cancer is breast cancer, pancreatic cancer, colon cancer, or B cell lymphoma. 4. The method according to claim 1, wherein the .beta.(1,6)-[poly-(1,3)-D-glucopyranosyl]-poly-.beta.(1,3)-D-glucopyranos- e and the anti-PD-1 antibody are in a single formulation. 5. The method according to claim 1, wherein the .beta.(1,6)-[poly-(1,3)-D-glucopyranosyl]-poly-.beta.(1,3)-D-glucopyranos- e and the anti-PD-1 antibody are in separate formulations. 6. The method according to claim 1, wherein the .beta.(1,6)-[poly-(1,3)-D-glucopyranosyl]-poly-.beta.(1,3)-D-glucopyranos- e is derived from yeast. 7. The method according to claim 6, wherein the yeast is Saccharomyces cerevisiae. 8. The method according to claim 1, wherein the .beta.(1,6)-[poly-(1,3)-D-glucopyranosyl]-poly-.beta.(1,3)-D-glucopyranos- e stimulates the subject's immune system. 9. The method according to claim 1, wherein the anti-PD-1 antibody is a non-complement-activating antibody. 10. The method according to claim 1, wherein the anti-PD-1 antibody is a complement-activating antibody. 11. The method according to claim 1, wherein the anti-PD-1 antibody is an IgG.sub.4 antibody. 12. The method according to claim 1, wherein the anti-PD-1 antibody is nivolumab or pembrolizumab. 13. The method according to claim 1, wherein the method further comprises administering bavituximab, ipilimumab, or tremelimumab. 14. The method according to claim 1, wherein the method further comprises administration of a tumor targeting antibody. 15. The method according to claim 1, wherein the method does not include IL-2 administration. 16. A method of stimulating a subject's immune system against cancer cells, the method comprising administering soluble .beta.(1,6)-[poly-(1,3)-D-glucopyranosyl]-poly-.beta.(1,3)-D-glucopyranos- e and an anti-PD-1 antibody. 17. The method according to claim 16, wherein the immune stimulation comprises activation of M1 macrophages, N1 neutrophils, NK cells, T cells, B cells or dendritic cells. 18. The method according to claim 16, wherein the immune stimulation comprises activation of interleukin-12, interferon-.gamma., tumor-necrosis factor .alpha., or a combination thereof. 19. A method of removing immune suppression in a tumor microenvironment, the method comprising administering soluble .beta.(1,6)-[poly-(1,3)-D-glucopyranosyl]-poly-.beta.(1,3)-D-glucopyranos- e and an anti-PD-1 antibody. 20. The method according to claim 19, wherein the method comprises suppression of M2 macrophages, N2 neutrophils, myeloid-derived suppressor cells, or a combination thereof.
