Chi-GVM Regimen for the Treatment of R/R PTCL

Summary

Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of lymphoproliferative diseases caused by mature T cells, accounting for approximately 10% of non-Hodgkin lymphomas (NHL). PTCLs have a worse prognosis than aggressive B-cell lymphomas; they are less responsive to standard anthracycline-based chemotherapy regimens and responses are less durable. In an analysis of 341 patients with newly diagnosed PTCL who received anthracycline chemotherapy, 3-year PFS and OS rates were 32% and 52%, respectively, significantly inferior to matched patients with diffuse large B-cell lymphoma (DLBCL).And patients who received consolidative hematopoietic cell transplantation (HCT) had no significant benefit. The prognosis of relapsed/refractory (R/R) patients is even worse. Among the 420 evaluable R/R PTCL patients in the COMPLETE registration study, the median OS of R/R patients were 29 months and 12 months respectively . There is still no effective second-line regimen that can improve patient survival, so treatment options urgently need to be optimized.We designed a randomized, prospective, multi-center phase II clinical trial to explore the efficacy of chidamide combined with gemcitabine, vinorelbine and Mitoxantrone Hydrochloride Liposome (Chi-GVM) in the treatment of patients with R/R PTCL. We expected to further improve ORR, PFS and OS.
