Evaluation of anti-CD38 monoclonal antibody-based immunotherapy in multiple myeloma with renal insufficiency: a systematic review and meta-analysis

Background: Renal impairment is one of the common characteristics of multiple myeloma (MM) and makes management of MM more complicated. Even though monoclonal antibodies targeting CD38 have wildly succeeded in treating MM, the addition of anti-CD38 monoclonal antibodies to standard therapy to treat MM patients with renal insufficiency is still poorly studied. Objectives: This study aims to evaluate whether using anti-CD38 monoclonal antibody-based immunotherapy would improve the prognosis of MM patients with renal insufficiency. Design: This is a systematic review and meta-analysis. Data sources and methods: We searched Scopus, PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE, Ovid Embase, and Web of Science Core Collection for randomized controlled trials that enrolled patients with MM who received CD38-targeting monoclonal antibody regimens and reported the efficacy and survival of MM with renal insufficiency. We then performed a meta-analysis to estimate the efficacy of adding anti-CD38 monoclonal antibodies to backbone regimens in MM with renal insufficiency. Results: = 0%). Conclusion: This meta-analysis suggests that the addition of anti-CD38 monoclonal antibodies benefits PFS in both NDMM and RRMM with renal insufficiency and OS in RRMM patients with renal insufficiency.
