A method or preparing immunologically primed cancer cells using cancer cells collected from a patient includes treating the collected cancer cells, ex vivo, with a toxic concentration of a compound that modifies sphingolipid metabolism, wherein the toxic concentration is sufficient to induce immunogenic cell death in the cancer cells. In an embodiment, the compound is 3-(4-Chloro-phenyl)-adamantane-1-carboxylic acid(pyridin-4-ylmethyl)-amide compound or a pharmaceutically acceptable salt thereof. In an embodiment, the immunologically primed cancer cells overexpress calreticulin on their surface. In an embodiment, the cancer cells are solid tumor cells. In an embodiment, the cancer cells are circulating tumor cells. In an embodiment, the method further comprises harvesting at least a portion of the immunologically primed cancer cells; and suspending the cells in phosphate-buffered saline. In an embodiment, the method further comprises shipping at least a portion of the immunologically primed cancer cells to a point of the patient's care.
一种制备免疫原激活癌细胞的方法涉及使用从患者收集的癌细胞,包括将收集的癌细胞在体外用一种改变鞘脂代谢的化合物的毒性浓度处理,其中毒性浓度足以诱导癌细胞发生免疫原性
细胞死亡。在一个实施例中,该化合物是3-(4-
氯苯基)-孔雀石-1-
羧酸(
吡啶-4-基甲基)-酰胺化合物或其药用可接受的盐。在一个实施例中,免疫原激活的癌细胞在其表面过表达
钙调蛋白。在一个实施例中,癌细胞是实体肿瘤细胞。在一个实施例中,癌细胞是循环肿瘤细胞。在一个实施例中,该方法进一步包括收集至少一部分免疫原激活的癌细胞;并将细胞悬浮在
磷酸盐缓冲盐
水中。在一个实施例中,该方法进一步包括将至少一部分免疫原激活的癌细胞运送至患者护理点。
