Abstract: Objective To mine information from the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) database to analyze adverse reaction signals of polatuzumab vedotin for clinical use. Methods The reports in the FAERS database collected between January 1, 2004 and June 30, 2023 were screened using SAS 9.4, and the signal values of the screened data were calculated by using the reporting odds ratio (ROR) and information component (IC) before being assessed according to the signal detection criteria. Results The number of reports that screened polatuzumab vedotin as the primary suspect drug (PS) was 636. After such signals were excluded as product defects, surgical and medical procedures and primary disease, 233 cases of positive polatuzumab vedotin-related AD signals were recorded. The ADE signals that ranked high in terms of the number of reported cases included off-label use, COVID-19, pyrexia, platelet count decreases and cytopenia. Among them, such signals as COVID-19, renal impairment and cardiac failure were not included in the labels. ADE signals with higher strength included subclavian vein stenosis, cytomegalovirus gastrointestinal ulcer and olfactory dysfunction, but subclavian vein stenosis and olfactory dysfunction were not included in the labels. Conclusion The suspicious signals for polatuzumab vedotin mined so far are generally consistent with those specified in the instructions. The use of polatuzumab vedotin requires not only close attention to such adverse reactions mentioned in the label as neutropenia, thrombocytopenia and peripheral neuropathy, but vigilance to potential ADE, such as renal failure, cardiac failure, thromboembolism, and COVID-19 infection. Blood test, cardiac and renal function should be closely monitored. Abnormalities of sensory nerves, motor nerves and autonomic nerves have to be observed. Immediate preventive and curative measures are needed to reduce the risk of clinical medications when necessary.
