Abstract: AIM: To evaluate the clinical efficacy and safety of oral proteasome inhibitor ixazomib in the treatment of multiple myeloma. METHODS: Eighty patients with multiple myeloma treated with ixazomib-containing therapy in the department of hematology, the First Affiliated Hospital of Anhui Medical University from January 2019 to December 2020 were retrospectively analyzed, including 38 patients with relapsed/refractory multiple myeloma (RRMM)and 42 patients who switched treatment due to adverse events (AEs) after initial induction therapy with bortezomib. Treatment was a two-drug or three-drug regimen containing ixazomib, and the clinical efficacy and safety of ixazomib were evaluated. RESULTS: The overall response rate (ORR) of relapsed/refractory patients was 50%, ≥ VGPR 21.05%; the ORR of patients who switched treatment was 83.33%, compared with the ORR before switching (78.57%), the response rate was further improved, of which 45.24%(19/42) patients had deepened response; the main hematological AEs included granulocyte and platelet count reduction and anemia, non-hematological AEs were mainly diarrhea and fatigue. CONCLUSION: Ixazomib shows good clinical efficacy and safety in patients with RRMM and bortezomib-intolerant MM.
