Study of Purinostat Mesylate for Injection in the Treatment of Relapsed or Refractory Diffuse Large B-cell Lymphoma (R/R DLBCL)

Purinostat mesylate for injection (PM) was the novel and highly potent Class Ia and IIb HDAC selective inhibitor. The results of regular blood sampling analysis of the mouse B-cell lymphoma model induced by ighmyc transgenic mice showed that the treatment of PM in each group reduced the proportion of peripheral blood tumor cells in mice. Therefore, PM has the potential to treat diffuse large B cell lymphoma. Compared with the blank control group, the body weight of the tumor-bearing animals in each dose of PM group did not decrease significantly during the treatment process, and the animals were in good condition during the whole experiment, indicating that the PM is efficacious and safe. Main purpose: To further explore the safe and effective dose of purinostat mesylate for injection in the treatment of relapsed or refractory diffuse large B-cell lymphoma. To evaluate the objective response rate (ORR) of purinostat mesylate for injection in the treatment of relapsed or refractory diffuse large B-cell lymphoma. Secondary purpose: To evaluate the time to tumor response (TTR), duration of response (DOR), disease control rate (DCR), and progression-free survival (PFS) in the treatment of relapsed or refractory diffuse large B-cell lymphoma with purinostat mesylate for injection ), overall survival (OS). Assessing the safety and tolerability of purinostat mesylate for injection in the treatment of relapsed or refractory diffuse large B-cell lymphoma. Exploratory purpose: To explore the biomarkers related to the efficacy of purinostat mesylate for injection.
