Efficacy and safety of daratumumab-based combined regimens for treatment of multiple myeloma / 白血病·淋巴瘤

ABSTRACT

Objective:To evaluate the safety and efficacy of daratumumab in the treatment of multiple myeloma (MM).Methods:The clinical data of 19 MM patients treated with daratumumab alone or in combination with chemotherapy regimens from June 2021 to December 2021 in the Affiliated Hospital of Jining Medical College were retrospectively analyzed, of which 2 patients received daratumumab alone, 6 cases received daratumumab combined with lenalidomide+dexamethasone (DRD) regimen, 1 case received daratumumab combined with liposomal doxorubicin+dexamethasone (DVD) regimen, 2 case received daratumumab combined with dexamethasone+cyclophosphamide+etoposide+cisplatin (DECP) regimen, 3 cases received daratumumab combined with isazomib+dexamethasone (ID) regimen, 2 cases received daratumumab combined with bortezomib+dexamethasone (BD) regimen, and 3 cases received daratumumab combined with dexamethasone (DD) regimen. The efficacy and incidence of adverse effects were analyzed.Results:Among the 19 patients, 8 had complete remission (CR), 1 had very good partial remission (VGPR), 5 had partial remission (PR), 1 had stable disease (SD), and 4 had progressive disease (PD). The overall response rate (ORR) was 73.7% (14/19). The median progression-free survival (PFS) time was 10.42 months (95% CI 8.04-12.79 months) and the median overall survival (OS) time was 52.06 months (95% CI 37.85-66.27 months). The main adverse reactions during treatment were grade 3 neutropenia in 3 cases, grade 3 lymphopenia in 3 cases, grade 2 anemia in 5 cases, grade 2 nausea and vomiting in 7 cases, and infusion-related adverse reactions in 7 cases. Conclusions:Daratumumab-based chemotherapy regimens for the treatment of MM patients can achieve great efficacy with good safety and tolerability.
