患者在CD123阳性CAR T细胞输注前3–10天接受淋巴清除方案,具体方案由主要研究者及方案团队确定。患者接受以下方案之一:第-4天和/或第-3天静脉给予环磷酰胺;第-5至-3天静脉给予磷酸氟达拉滨及环磷酰胺;或第-5至-3天静脉给予磷酸氟达拉滨,并于第-4天和/或第-3天静脉给予环磷酰胺。患者于第0天在15分钟内静脉输注自体或异基因CD123阳性CAR T细胞。若患者在第28天以后仍有疾病证据、CD123抗原持续表达且未发生剂量限制性毒性,可在28天后再次输注CD123阳性CAR T细胞。
这项I期试验研究淋巴清除化疗后给予基因改造T细胞治疗急性髓系白血病或浆细胞样树突状细胞肿瘤患者的副作用及最佳剂量。患者的疾病曾一度改善后复发,或对既往治疗无应答。免疫细胞是一类可识别并杀伤体内异常细胞的血细胞。本研究的免疫细胞产品由患者本人或其相关/无关供者的血细胞制备。研究者将额外的脱氧核糖核酸(DNA,即遗传物质)片段导入细胞,使其能够识别并杀伤癌细胞。将改造基因导入白细胞可能帮助机体建立杀伤癌细胞的免疫反应。
This phase I trial studies the side effects and the best dose of genetically modified T-cells after lymphodepleting chemotherapy in treating patients with acute myeloid leukemia or blastic plasmacytoid dendritic cell neoplasm that has returned after a period of improvement or has not responded to previous treatment. An immune cell is a type of blood cell that can recognize and kill abnormal cells in the body. The immune cell product will be made from patient or patient's donor (related or unrelated) blood cells. The immune cells are changed by inserting additional pieces of deoxyribonucleic acid (DNA) (genetic material) into the cell to make it recognize and kill cancer cells. Placing a modified gene into white blood cells may help the body build an immune response to kill cancer cells.
