Relapsed

To study the optimal therapeutic strategies for salvage treatment of refractory/relapsed AML, and to clarify the effectiveness and safety of various salvage treatment options. A prospective, multicenter, platform-type study was conducted to explore the overall response rate, tolerability, and survival of patients with R/R AML with different treatment regimens.

The investigators are doing this research study to assess the percentage of patients receiving stem cell transplantation for the type of blood cancer you have. They want to know how many patients get a transplant and why some patients do get a transplant while others do not. Also they want to explore why some patients elect not to undergo stem cell transplantation, when it is recommended by their physicians.

This is a single arm, open-label, dose escalation clinical study to evaluate the safety and tolerability of autologouschimeric antigen receptor T (CAR-T) cells targeting CD19/CD22/BCMA in patients with relapsed/refractory multiple myeloma.
