Abstrakt:	Objective: To investigate the clinical efficacy and safety of ixazomib-containing regimens in the treatment of patients with multiple myeloma (MM). Methods: A retrospective analysis was performed on the clinical efficacy and adverse reactions of 32 MM patients treated with a combined regimen containing ixazomib in the Hematology Department of the First People's Hospital of Lianyungang from January 2020 to February 2022. Among the 32 patients, 15 patients were relapsed and refractory multiple myeloma (R/RMM) (R/RMM group), 17 patients who responded to bortezomib induction therapy but converted to ixazomib-containing regimen due to adverse events (AE) or other reasons (conversion treatment group). The treatment included IPD regimen (ixazomib+pomalidomide+dexamethasone), IRD regimen (ixazomib+lenalidomide+dexamethasone), ICD regimen (ixazomib+cyclophosphamide+dexamethasone), ID regimen (ixazomib+dexamethasone). Results: Of 15 R/RMM patients, overall response rate (ORR) was 53.3%(8/15), among them, 1 achieved complete response (CR), 2 achieved very good partial response (VGPR) and 5 achieved partial response (PR). The ORR of the IPD, IRD, ICD and ID regimen group were 100%（3/3）, 42.9%（3/7）, 33.3%（1/3）, 50%（1/2）， respectively， there was no statistically significant difference in ORR between four groups (χ 2 =3.375, P =0.452). The ORR of patients was 50% after first-line therapy, 42.9% after second line therapy, 60% after third line therapy or more, with no statistically significant difference among them (χ 2 =2.164, P =0.730). In conversion treatment group, ORR was 88.2%(15/17), among them, 6 patients achieved CR, 5 patients achieved VGPR and 4 patients achieved PR. There was no statistically significant difference in ORR between the IPD（100%， 3/3）, IRD（100%， 6/6）, ICD（100%， 3/3） and ID（60%， 3/5） regimen groups (χ 2 =3.737， P =0.184). The median progression-free survival (PFS) time of R/RMM patients was 9 months (95% CI : 6.6-11.4 months), the median overall survival (OS) time was 18 months (95% CI : 11.8-24.4 months). The median PFS time of conversion treatment group was 15 months (95% CI : 7.3-22.7 months), the median OS time not reached. A total of 10 patients suffered grade 3- 4 adverse event (AE). The common hematological toxicities were leukocytopenia, anemia, thrombocytopenia. The common non-hematological toxicities were gastrointestinal symptoms (diarrhea, nausea and vomit), peripheral neuropathy, fatigue and infections. Grade 1-2 peripheral neurotoxicity occurred in 7 patients. Conclusion: The ixazomib-based chemotherapy regimens are safe and effective in R/RMM therapy, particularly for conversion patients who are effective for bortezomib therapy. The AE was manageable and safe.
