Objective: To assess the short-term efficacy and safety of ixazomib in Chinese multiple myeloma (MM) patients in the real world.
Methods: Fifty-nine MM patients who received at least one cycle of ixazomib-based therapy between 1 June 2018 and 30 September 2019 were retrospectively analyzed in Tianjin Medical University General Hospital. Thirteen newly diagnosed MM (NDMM), 13 refractory/relapsed MM (RRMM) and 33 continuous therapy (27 bortezomib peripheral neuritis (PN) intolerant and six maintenance therapy) MM patients were included. The indicated overall response rate (ORR), time to overall response (TOR), and adverse events (AEs) were investigated.
Results: The ORR in NDMM was 76.9%, with one complete response (CR), five very good partial response (VGPR), four partial response (PR), median PFS, and TOR were 122 (66– 272) days and 49 (22– 108) days. The ORR in RRMM was 46.2%, with one CR, two VGPR, three PR, median PFS, and TOR were 79 (28– 169) days and 59 (23– 88) days. The ORR in continuous therapy MM patients was 100%, with nine stringent CR, 15 CR, six VGPR and three PR, median TOR was 75 (25– 141) days. There were no significant differences regarding ORR between patients with cytogenetic high risk and standard risk in three subgroups (all P> 0.05). The most frequent hematological AEs were anemia (13.6%) and thrombocytopenia (10.2%). The most common nonhematological AEs were PN (25.0%) and diarrhea (13.6%).
Conclusion: The real-world data demonstrated that ixazomib-based therapy was generally effective and safe in the short term for MM patients.
