Popis: Background: Bortezomib is used as first-line therapy for multiple myeloma. Observational studies based on the FDA Adverse Event Reporting System database analysis and systematic reviews indicate that the incidence of peripheral neuropathy (PN) and tumor lysis syndrome (TLS) tends to be higher with bortezomib than that of other drugs. In a comprehensive analysis assessing drugs that cause PN in Japanese patients, the incidence of bortezomib-induced adverse events (AEs) was reportedly high. However, a comprehensive assessment of bortezomib is lacking. Objectives: The purpose of this study was to determine the frequency of bortezomib AEs in Japanese patients and to determine the incidence, time to onset, and post hoc outcomes of unique AEs using the Japanese Adverse Drug Event Report database. Method: To investigate the association between bortezomib and AEs, we analyzed the Japanese Adverse Drug Event Report database, which contains spontaneous AE reports submitted to the Pharmaceuticals and Medical Devices Agency from April 2004 to December 2020. Criteria indicating the presence of an AE signal were met when the following requirements were fulfilled: proportional reporting ratios ≥2 and χ2 ≥ 4. Time to onset and post-event outcomes were analyzed for characteristic AEs. Results: Among 26 extracted AEs, 13 presented AE signals. The post-exposure outcomes of 12 AEs showed fatal outcomes at rates exceeding 10%, including cardiac failure (30%), lung disorder (24%), pneumonia (18%), and TLS (10%). Furthermore, a histogram of time to onset revealed that the 12 AEs were concentrated from the beginning to approximately 1 month after bortezomib administration. The median onset times for cardiac failure, lung disorder, pneumonia, and TLS were 28, 13, 42, and 5 days, respectively. Conclusions: Cardiac failure, lung disorder, pneumonia, and TLS had a higher rate of fatal clinical outcomes after onset than other AEs. These AEs exhibited a greater onset tendency in the early post-dose period. This study suggests that there is a need to monitor signs of cardiac failure, lung disorder, pneumonia, and TLS, potentially resulting in serious outcomes.
