简要总结
Phase I was a single arm, open label, dose increasing study to explore the safety, tolerance and Cytodynamic characteristics of the drug, and to preliminarily observe the efficacy of the study drug in relapsed / refractory CD7 Positive hematolymph system malignant tumor patients, so as to explore the clinical applicable dose of phase II. Since the activity and toxicity of cellular drugs (long-term survival drugs) do not have obvious dose dependence, and the increase of their dose may be accompanied by the increase of toxicity, rather than necessary for therapeutic effect, it is not necessarily suitable to recommend the effective dose according to the maximum tolerable dose (MTD). Therefore, this study will be based on the safety data, as well as the preliminary efficacy, efficacy and drug The end point of pharmacokinetics (ORR, the content of CD7 Positive Cells, the expansion and duration of car-t cells) were comprehensively considered to determine the recommended dose for phase II clinical trial.Main research purposes Objective to evaluate the safety and tolerability of T cell injection targeting CD7 autologous chimeric antigen receptor in the treatment of relapsed / refractory CD7 Positive hematological and lymphoid malignancies.
