Elotuzumab was approved by the US FDA in 2015 as a new drug for the treatment of multiple myeloma（MM）, and it became a new choice for MM patients. The drug is the first immunostimulatory drug to treat MM and used to treat recurrent/refractory multiple myeloma（R/RMM） in combination with lenalidomide and dexamethasone. Therefore, we collected the reports from existing clinical trials to analyze the efficacy of the drug in clinical applications to better evaluate the effects of the drug on R/RMM. The search strategy used ＂elotuzumab＂ and ＂multiple myeloma＂ as keywords to search from the database of Cochrane, Embase, Pub Med and Medline. The heterogeneity among the studies was assessed using the Cochrane χ~2 test, and its extent was evaluated using I^2 statistics. A P value of less than 0.05 was considered as statistically significant. All meta-analyses were conducted with R Software 3.3.2. We identified eight prospective studies consisting of 608 MM patients. The meta-analysis showed that the overall response rate（ORR） was 63%, 162 patients（26.6%） achieved a very good partial response rate（VGPR）, and 34 patients（5.59%） achieved complete response rate（CR）. The most common adverse effects of the drug included anemia, lymphopenia, thrombocytopenia, neutropenia and fatigue. Therefore, elotuzumab combination regimens offered clinical benefits to R/RMM patients, and such a combination therapy was a suitable option for continuous treatment for R/RMM patients.
