To assess tumor immune activity, hierarchical clustering was applied to 159 BC samples based on cellular positivity for the defined immune cellular markers (CD3/CD4/CD8/FOXP3/CD20/PD-1/PD-L1/LAG3/TIGIT), divided into two clusters. There was a “hot cluster” (25%) consisting of patients with a high expression of these markers and a “cold cluster” (75%) comprising those without. The expression of CD39, CD44, CD68, CD163, IDO1, and Ki67 was significantly higher in tumors in the hot cluster. Immunologically, high-grade T1 tumors were significantly hotter, whereas tumors that had progressed to muscle invasion turned cold.

In this study, we show that a multigene panel for plasma LB can also be applied to bile cfDNA for comparing driver gene mutation detection in other sources (plasma and tumor tissues of the corresponding patients). We collected cfDNA samples from the bile of 24 biliary tract cancer cases. These included 17 cholangiocarcinomas, three ampullary carcinoma, two pancreatic cancers, one intraductal papillary mucinous carcinoma, and one insulinoma. Seventeen plasma samples were obtained from the corresponding patients before surgical resection and subjected to the LiquidPlex multigene panel LB system. We applied a machine learning approach to classify possible tumor-derived variants among the prefiltered variant calls by a LiquidPlex analytical package with high fidelity. Among the 17 cholangiocarcinomas, we could detect cancer driver mutations in the bile of 10 cases using the LiquidPlex system. Of the biliary tract cancer cases examined with this method, 13 (54%) and 4 (17%) resulted in positive cancer driver mutation detection in the bile and plasma cfDNAs, respectively.

The novel human CD40 (hCD40) agonist KHK2840 is a fully human anti-CD40 IgG2 agonistic antibody that is Fc-engineered to minimize complement-dependent cytotoxicity and antibody-dependent cellular cytotoxicity. Compared to other hCD40 agonists, KHK2840 exhibited the most potent hCD40 agonistic signal in tumor-bearing hCD40 transgenic mice and human peripheral blood B cells. Moreover, KHK2840 enhanced the antitumor efficacy of the antiprogrammed cell death 1 antibody and paclitaxel. Comprehensive immune profiling revealed that the antitumor immune response of the triple combination involved tumor-draining lymph nodes in addition to tumor microenvironments. This suggests that a coordinated antitumor immune response between tumors and lymph nodes may underlie the synergistic antitumor efficacy of the triple combination therapy. Finally, a toxicology study in cynomolgus monkeys demonstrated that KHK2840 activated the CD40 signal with tolerable toxicological properties.

However, the immune checkpoint inhibitors, especially anti-CTLA-4 are currently administered intravenously (i.v.), resulting in limited efficacy in controlling solid tumor and inhibiting metastases, and the method of administration has not been optimized. Here, we show that a combination of local radiotherapy and administration of anti-CTLA-4 antibodies using a lymphatic drug delivery system (LDDS) suppresses solid tumor and metastases.
