Venetoclax-based combination therapy in R/R DLBCL patients with failure of CAR-T therapy.

There are few effective therapeutic options available for R/R DLBCL patients who have undergone CAR-T therapy. We retrospectively assessed 10 R/R DLBCL patients with complete clinical records who received venetoclax-based combination therapy following CAR-T therapy failed in our center between July 2020 and December 2021. After receiving CAR-T therapy, they all relapsed within a few months. As salvage regimens, they were all given venetoclax-based combination therapy. The objective response rate (ORR) was 80 percent, and the complete response rate was 30 percent. At the time of the analysis, 7 patients were still living. Our research has demonstrated that venetoclax-based combination treatment for R/R DLBCL patients who failed CAR-T therapy has a high effectiveness and manageable toxicity.
