ABSTRACT
Objective:
To explore the efficacy and safety of domestic bortezomib in combination with lenalidomide and dexamethasone in the treatment of newly diagnosed multiple myeloma (NDMM) .Methods:
This multicenter, prospective, single-arm clinical study included 126 patients with NDMM admitted to seven hospitals between December 2019 and January 2022. All patients received domestic bortezomib in combination with lenalidomide and dexamethasone (BLD regimen), and the efficacy, prognostic factors, and safety were analyzed.Results:
Among the 126 patients with NDMM, 118 completed four cycles of treatment, with an overall response rate (ORR) of 93.22% (110/118) and a ≥very good partial response (VGPR) rate of 68.64% (81/118). Ultimately, 114 patients completed at least eight cycles of treatment, with an ORR of 92.98% (106/114) and a ≥VGPR rate of 77.19% (88/114). Eighteen patients underwent autologous hematopoietic stem cell transplantation after completing 6-8 cycles of the BLD regimen, with an ORR of 100% (18/18) and a ≥VGPR rate of 88.9% (16/18). The proportion of patients achieving ≥VGPR increased with the treatment duration, and factors such as staging and age did not significantly affect efficacy. Single-factor analysis showed that R2-ISS stage â ¢/â £, blood calcium >2.27 mmol/L, and failure to achieve VGPR after six cycles were adverse prognostic factors for progression-free survival (PFS) (P<0.05), whereas failure to achieve VGPR after six cycles was an adverse prognostic factor for overall survival (OS) (P<0.001). Multifactor analysis demonstrated that failure to achieve VGPR after six cycles is an independent adverse prognostic factor for PFS (P=0.002). The incidence of hematologic adverse reactions was 16.7% (19/114), and nonhematologic adverse reactions were mainly mild to moderate, with no significant cardiac or renal adverse reactions observed.Conclusion:
The BLD regimen is effective in treating NDMM, in which patients with high-risk genetic features are still achieving a high ≥VGPR rate, and the overall safety is good.Key words
