| アブストラクト | BACKGROUND: Tafasitamab is the first anti-CD19 monoclonal antibody approved for relapsed/refractory diffuse large B-cell lymphoma patients ineligible for autologous stem cell transplantation. The study was designed to evaluate tafasitamab-associated adverse events (AEs) by data mining the United States Food and Drug Administration Adverse Event Reporting System (FAERS). RESEARCH DESIGN AND METHODS: A disproportionality analysis was performed to assess the safety profile of tafasitamab based on the reports from the FAERS database between 2020Q3 and 2023Q3. Proportional reporting ratio (PRR) and empirical Bayesian geometric mean (EBGM) were used to identify the signals of AEs in patients receiving tafasitamab. RESULTS: A total of 529 reports with tafasitamab as the primary suspect drug were collected, including 1,262 AEs. Of these, 28 repeated AEs were identified using two algorithms. After excluding events unrelated to drug therapy, the top five repeated AEs by intensity ranking were cytopenia, immunosuppression, neutropenic sepsis, blood lactate dehydrogenase increased, and hematotoxicity. Unexpected significant AEs included polyneuropathy, splenomegaly, hemophagocytic lymphohistiocytosis, hypercalcemia, and ascites. CONCLUSIONS: This study provides additional evidence for risk identification of tafasitamab in the real world, which could help clinicians and pharmacists increase vigilance and improve the safety of tafasitamab in clinical practice. |
