Chimeric antigen receptor T-cell therapy-induced nervous system toxicity: a real-world study based on the FDA Adverse Event Reporting System database.

BACKGROUND: Nervous system toxicity (NST) is one of the most frequent and dangerous side effects of chimeric antigen receptor T-cell (CAR-T) therapy, which is an effective treatment for related tumors in most relapsed/refractory (r/r) hematologic malignancies. Current clinical trial data do not fully reflect the real-world situation. Therefore, this study evaluated the NST of CAR-T therapy using the FDA Adverse Event Reporting System (FAERS). METHODS: Data were retrieved from FAERS for the period from January 1, 2017 to March 31, 2023. Disproportionality analysis and Bayesian analysis were used for data mining. The reporting odds ratio (ROR) for NST with 95% confidence interval (CI) was calculated for each CAR-T product. The time to onset (TTO) and clinical outcomes due to CAR-T therapy-associated NST were assessed. RESULTS: Overall, 6946 cases of NST associated with CAR-T therapy were identified. The patients had a median age of 61 years (interquartile range [IQR]: 47-69 years). Significant signals were observed for all CAR-T products (ROR: 2.19, 95% CI: 2.13-2.44). Anti-CD19 CAR-T products showed a higher NST signal than anti-B cell maturation antigen (BCMA) CAR-T products (ROR025 2.13 vs. 1.98). Brexucabtagene autoleucel (ROR: 3.17, 95% CI: 2.90-3.47) and axicabtagene ciloleucel (ROR: 2.92, 95% CI: 2.81-3.03) had the two highest NST signals. For the preferred term "brain edema," the highest signals were obtained for CD28 CAR-T products. The median TTO of NST for all CAR-T products was 7 days (IQR: 3-17 days). The proportion of death, life-threatening and hospitalization adverse events associated with NST was 20.06%, 7.21%, and 32.70%, respectively. The proportion of death outcomes was higher in patients treated with tisagenlecleucel (30.36%) than in those treated with other CAR-T products, except ciltacabtagene autoleucel (P < 0.001). The proportion of hospitalizations was significantly higher for lisocabtagene maraleucel-associated NST (53.85%) than for other drugs, except for ciltacabtagene autoleucel (P < 0.001). CONCLUSIONS: NST is more closely associated with anti-CD19 CAR-Ts and CAR-Ts containing CD28. Serious NST (brain oedema) is likely to occur with CAR-Ts that contain CD28. CAR-T-related NST warrants greater attention owing to the high proportion of serious adverse events and delayed NST.

PARP inhibitor-related acute renal failure: a real-world study based on the FDA adverse event reporting system database.

BACKGROUND: Current clinical trial data on PARP inhibitors (PARPis)-related acute renal failure (ARF) are not entirely representative of real-world situations. Therefore, in this study, the US Food and Drug Administration Adverse Event Reporting System (FAERS) was used to evaluate PARPis-related ARF. RESEARCH DESIGN AND METHODS: Data were obtained from 1 January 2015, to 30 September 2023. ARF event reports were analyzed based on four algorithms. The time-to-onset (TTO) and clinical outcomes of PARPis-associated ARF were assessed. RESULTS: The total included cases were 2726. Significant signals were observed for olaparib, niraparib, and rucaparib (reporting odds ratio (ROR): 1.62, 95% confidence interval (CI): 1.49-1.78, 1.25, 95% CI: 1.19-1.32 and 1.59, 95% CI: 1.47-1.72 respectively). The median TTO of ARF onset was 57, 36, and 85 days for olaparib, niraparib, and rucaparib, respectively. The proportion of deaths with olaparib (9.88%) was significantly higher than for niraparib (2.52%) and rucaparib (2.94%) (p < 0.005). The proportion of life-threatening adverse events associated with niraparib (4.89%) was significantly higher than for rucaparib (0.98%) (p < 0.005). CONCLUSIONS: ARF and PARPi were related, with the exception of talazoparib. More emphasis should be given to PARPis-related ARF due to the high proportion of serious AEs and delayed adverse reactions.

Cardiovascular toxicities of selective ret-specific tyrosine kinase inhibitors: a pharmacovigilance study based on the United States Food and Drug Administration Adverse Event Reporting System database.

BACKGROUND: Selective RET-specific tyrosine kinase inhibitors (RET-TKIs) treat RET fusion-positive non-small cell lung cancer (NSCLC), but studies on their cardiovascular toxicities are limited. This study aimed to characterize the cardiovascular toxicities associated with selective RET-TKI in real-world settings. RESEARCH DESIGN AND METHODS: Data from the United States Food and Drug Administration Adverse Event Reporting System database from 1 January 2020 to 30 June 2023, were analyzed. Two disproportionality methods, information component and reporting odds ratio (ROR) were used. RESULTS: Both pralsetinib and selpercatinib showed positive signals for hypertension (pralsetinib: ROR: 5.25, 95% CI: 4.40-6.26; selpercatinib: ROR: 2.68, 95% CI: 1.87-3.82). Additionally, pralsetinib showed a positive signal for ischemic heart disease (ROR: 3.92, 95% CI: 2.94-5.23), and selpercatinib for torsade de pointes/QT prolongation (ROR: 2.65, 95% CI: 1.74-4.04). The median time to onset(TTO) of cardiovascular toxicities was 33 days (IQR: 9-73 days) for pralsetinib and 15 days (IQR: 10-50 days) for selpercatinib. The proportion of deaths, life-threatening events, and hospitalizations due to cardiovascular toxicities were 8.57%, 1.19%, and 31.43%, respectively, for total selective RET-TKI. CONCLUSIONS: Selective RET-TKIs are related to multiple cardiovascular toxicities. Pralsetinib was linked to ischemic heart disease, and selpercatinib to torsade de pointes/QT prolongation and thrombotic events.

Pharmacovigilance study of the association between peripheral neuropathy and antibody-drug conjugates using the FDA adverse event reporting system.

Antibody-drug conjugates (ADCs) are among the fastest-growing classes of anticancer drugs, making it crucial to evaluate their potential for causing peripheral neuropathy. We analyzed data from the FAERS database (January 1, 2014, to June 30, 2023) using disproportionality and Bayesian methods. We identified 3076 cases of ADC-associated peripheral neuropathy. Our study revealed significant signals for all ADCs (ROR 1.82, 95% CI 1.76-1.89). ADCs with tubulin-binding payloads showed significant peripheral neuropathy signals (ROR 2.31, 95% CI 2.23-2.40), whereas those with DNA-targeting (ROR 0.48, 95% CI 0.39-0.59) and topoisomerase 1 inhibitor (ROR 0.56, 95% CI 0.48-0.66) payloads exhibited non-significant signals. Signals for peripheral sensory neuropathy were 4.83, 2.44, 2.74, and 2.21 (calculated based on IC025) for brentuximab vedotin, trastuzumab emtansine, enfortumab vedotin, and polatuzumab vedotin, while signals for peripheral motor neuropathy were 5.31, 0.34, 2.27, and 0.03, respectively. The median time to onset for all ADCs was 127 days (interquartile range 40-457). Tisotumab vedotin had the highest hospitalization rate at 26.67%, followed by brentuximab vedotin at 25.5%. Trastuzumab emtansine had the highest mortality rate ,with 80 deaths (11.96%) among 669 cases. Based on FAERS database, only ADCs with tubulin-binding payloads exhibited significant peripheral neuropathy signals. Brentuximab vedotin and enfortumab vedotin showed similar profiles for peripheral sensory neuropathy and motor neuropathy. Given the delayed time to onset and potentially poor outcomes, ADC-related peripheral neuropathy warrants significant attention.

Immune-related adverse events of immune checkpoint inhibitors combined with angiogenesis inhibitors: A real-world pharmacovigilance analysis of the FDA Adverse Event Reporting System (FAERS) database (2014-2022).

INTRODUCTION: Although immune checkpoint inhibitors (ICIs) combined with angiogenesis inhibitors (AGIs) has become increasingly used for cancers, the impact of combination therapy on immune-related adverse events (irAEs) in real-world settings has not been well elucidated to date. METHODS: The FDA Adverse Event Reporting System (FAERS) database from 2014 to 2022 was retrospectively queried to extract reports of irAEs referred as standardized MedDRA queries (SMQs), preferred terms (PTs) and system organ classes (SOCs). To perform disproportionality analysis, information component (IC) and reporting odds ratio (ROR) were calculated and lower limit of 95 % confidence interval (CI) for IC (IC025) > 0 or ROR (ROR025) > 1 with at least 3 reports was considered statistically significant. RESULTS: Compared to ICIs alone, ICIs + AGIs demonstrated a lower IC025/ROR025 for irAEs-SMQ (2.343/5.082 vs. 1.826/3.563). Regarding irAEs-PTs, there were fewer irAEs-PTs of significant value in ICIs + AGIs than ICIs alone (57 vs. 150 PTs) and lower signal value for most PTs (88 %) in ICIs + AGIs. Moreover, lower IC025 for most of irAEs-SOCs in ICIs + AGIs (11/13) compared with ICIs alone was observed. As for outcomes of irAEs, ICIs + AGIs showed a lower frequency of "fatal" for irAEs-SMQ than ICIs alone (4.88 % vs. 7.83 %), so as in cardiac disorder (SOC) (15.45 % vs. 26.37 %), and respiratory, thoracic and mediastinal disorders (SOC) (13.74 % vs. 20.06 %). Similarly, there were lower occurrence and fewer fatality of irAEs in ICIs + AGIs + chemotherapy (CT) than ICIs + CT. CONCLUSION: ICIs combined with AGIs may reduce incidence and mortality for most of irAEs compared to ICIs alone whether or not with CT.

Immune-related interstitial lung disease induced by different immune checkpoint inhibitors regimens: A real-world study from 2014 to 2022 based on FAERS databases.

This study further approaches immune-related interstitial lung disease adverse event in patients undergoing immune checkpoint inhibitor (ICI) monotherapy, ICI plus chemotherapy and ICI plus anti-VEGF therapy in the postmarketing period. Reports for ICI-related interstitial lung disease adverse event from the FDA Adverse Event Reporting System (FAERS) database between 2014 and 2022 were analysed in this study. The reporting odds ratio (ROR) and Bayesian confidence propagation neural networks of information components (IC) were computed to identify disproportionate reporting of ICI-related interstitial lung disease. 44,964,609 records were extracted from the FAERS database, with 9150 records for interstitial lung disease after ICI treatment. Men had a slightly higher reporting frequency than women (63.07% vs. 25.69%). The morbidity rate (2.05%) of acute respiratory distress syndrome was low, the fatality rate (67.55%) was the highest, the time to onset was relatively short. Within 3 months, the cumulative proportion of ICI-related interstitial lung disease records was 75.03%. The ICI plus anti-VEGF therapy group had the lowest frequency of interstitial lung disease adverse events compared to the ICI monotherapy group and the ICI plus chemotherapy group (IC025 = 1.72, IC025 = 3.21, IC025 = 3.22). Moreover, ICI plus anti-VEGF therapy group had the narrowest spectrum of interstitial lung disease among these three therapeutic regimens. This study showed substantial characteristics of a spectrum of interstitial lung disease adverse events after different ICI regimens. Notably, ICI plus anti-VEGF therapy might be a treatment method that can to some extent control ICI-related interstitial lung disease. These data provide some important information for clinicians to weigh the risks and benefits of different ICI regimens.

Cardiovascular toxicity profiles of immune checkpoint inhibitors with or without angiogenesis inhibitors: a real-world pharmacovigilance analysis based on the FAERS database from 2014 to 2022.

Background: Immune checkpoint inhibitors (ICIs) combined with angiogenesis inhibitors (AGIs) have become increasingly available for multiple types of cancers, although the cardiovascular safety profiles of this combination therapy in real-world settings have not been elucidated to date. Therefore, we aimed to comprehensively investigate the cardiovascular toxicity profiles of ICIs combined with AGIs in comparison with ICIs alone. Methods: The Food and Drug Administration Adverse Event Reporting System (FAERS) database from the 1st quarter of 2014 to the 1st quarter of 2022 was retrospectively queried to extract reports of cardiovascular adverse events (AEs) associated with ICIs alone, AGIs alone and combination therapy. To perform disproportionality analysis, the reporting odds ratios (RORs) and information components (ICs) were calculated with statistical shrinkage transformation formulas and a lower limit of the 95% confidence interval (CI) for ROR (ROR025) > 1 or IC (IC025) > 0 with at least 3 reports was considered statistically significant. Results: A total of 18 854 cardiovascular AE cases/26 059 reports for ICIs alone, 47 168 cases/67 595 reports for AGIs alone, and 3 978 cases/5 263 reports for combination therapy were extracted. Compared to the entire database of patients without AGIs or ICIs, cardiovascular AEs were overreported in patients with combination therapy (IC025/ROR025 = 0.559/1.478), showing stronger signal strength than those taking ICIs alone (IC025/ROR025 = 0.118/1.086) or AGIs alone (IC025/ROR025 = 0.323/1.252). Importantly, compared with ICIs alone, combination therapy showed a decrease in signal strength for noninfectious myocarditis/pericarditis (IC025/ROR025 = 1.142/2.216 vs. IC025/ROR025 = 0.673/1.614), while an increase in signal value for embolic and thrombotic events (IC025/ROR025 = 0.147/1.111 vs. IC025/ROR025 = 0.591/1.519). For outcomes of cardiovascular AEs, the frequency of death and life-threatening AEs was lower for combination therapy than ICIs alone in noninfectious myocarditis/pericarditis (37.7% vs. 49.2%) as well as in embolic and thrombotic events (29.9% vs. 39.6%). Analysis among indications of cancer showed similar findings. Conclusion: Overall, ICIs combined with AGIs showed a greater risk of cardiovascular AEs than ICIs alone, mainly due to an increase in embolic and thrombotic events while a decrease in noninfectious myocarditis/pericarditis. In addition, compared with ICIs alone, combination therapy presented a lower frequency of death and life-threatening in noninfectious myocarditis/pericarditis and embolic and thrombotic events.

Haematopoietic cytopenia associated with cyclin-dependent kinase 4/6 inhibitors: A real-world study of data from the food and drug administration adverse event reporting system database.

OBJECTIVE: The haematopoietic cytopenia (HC) of the cyclin-dependent kinase (CDK)4/6 inhibitors was evaluated using the Food and Drug Administration Adverse Event Reporting System (FAERS). METHOD: Data from 1 January 2015 to 31 December 2021 has been retrieved from the FAERS database. Disproportionality analysis and Bayesian analysis were utilized in the data mining. The reporting odds ratio (ROR) with 95% confidence interval (CI) for HC was calculated for each CDK 4/6 inhibitor agent. Clinical features of the patients were collected and compared between death outcome and non-death outcome groups. Time to onset (TTO), proportion of deaths, life-threatening and hospitalizations of CDK 4/6 inhibitors-associated HC were also studied. RESULTS: A total of 17,235 cases of HC associated with CDK 4/6 inhibitors were identified with a median age of 65 years (interquartile range [IQR] 57-73). Palbociclib appeared the strongest signal, with the highest (ROR 9.64, 95% CI 9.46-9.83), followed by ribociclib (ROR 6.38, 95% CI 6.04-6.73) and then abemaciclib (ROR 2.72, 95% CI 2.49-2.97). Patients aged 18-64 had a higher proportion of deaths than those aged 65-84 (12.21% vs. 9.91%, p = 0.001). In Africa and Asia, the proportions of deaths were higher (31.65% and 26.13%, respectively). The median TTO was 26 days (IQR 14-65) for abemaciclib, 33 days (IQR 15-134) for palbociclib and 23 days (IQR 14-69) for ribociclib, respectively. The highest proportion of deaths, life-threatening and hospitalizations all occurred in abemaciclib (13.00%, 5.42% and 44.04%, respectively). CONCLUSIONS: Greater proportions of deaths occurred in Africa and Asia. HC may occur early in any CDK 4/6 inhibitor regimen. Abemaciclib had the highest proportion of deaths, life-threatening and hospitalizations. Health care workers should be more concerned about CDK 4/6 inhibitors. The higher proportions of serious events, including deaths, from Africa and Asia, as well as for abemaciclib, deserve further investigations through additional pharmacoepidemiological approaches.

Cardiovascular toxicity associated with angiogenesis inhibitors: A comprehensive pharmacovigilance analysis based on the FDA Adverse Event Reporting System database from 2014 to 2021.

Background: The profiles of cardiovascular toxicity associated with angiogenesis inhibitors, including intravenous monoclonal antibodies (mAbs) and oral tyrosine kinase inhibitors (TKIs), targeting vascular endothelial growth factor (VEGF) remain poorly elucidated in real-world settings. This pharmacovigilance analysis aimed to comprehensively investigate the frequency, spectrum, timing, and outcomes of cardiovascular toxicities associated with angiogenesis inhibitors and to explore the differences in such patterns between mAbs and TKIs. Methods: Disproportionality analysis was performed by leveraging reports from the FDA Adverse Event Reporting System (FAERS) database from 2014 to 2021. Cardiovascular adverse events (AEs) were grouped into nine narrow categories using the Standardized Medical Dictionary for Regulatory Activities (MedDRA) Queries (SMQs). Reporting odds ratio (ROR) and information components (ICs) were calculated with statistical shrinkage transformation formulas and a lower limit of 95% confidence interval (CI) for ROR (ROR025) > 1 or IC (IC025) > 0, with at least three reports being considered statistically significant. Results: A total of 757,577 reports of angiogenesis inhibitors and 70,668 (9.3%) reports of cardiovascular AEs were extracted. Significant disproportionality was detected in angiogenesis inhibitors for cardiovascular AEs (IC025/ROR025 = 0.35/1.27). Bevacizumab (31.8%), a mAb, presented the largest number of reports, followed by sunitinib (12.4%), a TKI. Hypertension (SMQ) was detected with the strongest signal value (IC025/ROR025 = 1.73/3.33), followed by embolic and thrombotic events (SMQ) (IC025/ROR025 = 0.32/1.26). Hypertension showed the shortest time to onset with a median (interquartile range) value of 23 (8, 69) days, while embolic and thrombotic events had the longest value of 51 (16, 153) days. Notably, hypertension presented the lowest proportions of death and life-threatening events (10.9%), whereas embolic and thrombotic events posed the highest (29.3%). Furthermore, both mAbs (IC025/ROR025 = 0.47/1.39) and TKIs (IC025/ROR025 = 0.30/1.23) showed increased cardiovascular AEs. Hypertension was detected in both agents (IC025/ROR025 = 1.53/2.90 for mAbs and IC025/ROR025 = 1.83/3.56 for TKIs) with a shorter time to onset of 17 (6, 48) days for TKIs than mAbs of 42 (14, 131) days. By contrast, embolic and thrombotic events were detected for mAbs (IC025/ROR025 = 0.90/1.87) without TKI (IC025/ROR025 = -0.08/0.95). Conclusion: Angiogenesis inhibitors were associated with increased cardiovascular toxicity with a discrepancy between intravenous mAbs and oral TKIs, deserving distinct monitoring and appropriate management.

Respiratory system toxicity induced by immune checkpoint inhibitors: A real-world study based on the FDA adverse event reporting system database.

Background: Immune checkpoint inhibitors (ICIs), the treatment of multiple cancer types, can be associated with respiratory system adverse events (AEs). The aim of this study is to quantify the association of respiratory system AEs and ICIs and to characterize the profiles of ICI-related respiratory system complications from Food and Drug Administration Adverse Event Reporting System (FAERS) data. Methods: The disproportionality of respiratory system AE-related ICIs based on FAERS data from January 2014 to September 2021 was analyzed using the reporting odds ratio (ROR) and information component (IC) as measures of potential risk increase. Results: A total of 38,415,849 records were involved; among these, 36,923 records related to respiratory system AEs after ICI treatment were identified. In the first 3 months, the cumulative proportion of respiratory system AEs was 75.40%. Men had a slightly higher reporting frequency than that of women (ROR = 1.74, 95% CI: 1.70-1.78). Death cases had a slightly higher reporting frequency in ICI-associated respiratory system AEs than that of other drug-associated respiratory system AEs (ROR = 1.40, 95% CI: 1.38-1.41). Anti-programmed cell death 1 (PD-1) drugs and anti-programmed cell death ligand 1 (PD-L1) drugs were significantly associated with respiratory system toxicities. However, anti-cytotoxic T lymphocyte-associated protein 4 (CTLA-4) drugs did not demonstrate an association with respiratory system toxicities. Interstitial lung disease and pneumonitis were found to be significantly associated with all eight types of ICIs. In addition, 7 in 10 class-specific respiratory system AEs (lower respiratory tract disorders, pleural disorders, pulmonary vascular disorders, respiratory disorders not elsewhere classified (NEC), respiratory tract infections, respiratory tract neoplasms, and thoracic disorders) were associated with ICIs. The signal values of IC025 were from 0.08 to 2.66. Conclusions: Overall, this study showed a high reporting frequency of respiratory system toxicities caused by ICIs. Early recognition and management of ICI-related respiratory system AEs are of vital importance in practice. Maximizing the benefit while reducing potential respiratory system toxicities of ICIs should become a priority.

Development of the Practice of Pharmaceutical Care for Cancer Pain Management in Outpatient Clinics Using the Delphi Method.

Background: There exists no broad agreement of experts on the practice of pharmaceutical care for cancer pain management in outpatient clinics. Objectives: This study aimed to use the Delphi consensus process to provide expert recommendations on the practice of cancer pain management in outpatient clinics from the point of view of pharmaceutical care in clinical practice and future clinical trials. Methods: A comprehensive literature review was conducted to draft the initial practice. In this process, 30-40 senior experts from various provinces in China were invited to rank the items of practice during the two Delphi consultations. The definitions of consensus included a combination with an average score of ≥4, the percentage of experts rating the scores at >4 points, and the coefficient of variation of the scores. Results: The expert panel comprised 18 pharmacists, 3 anesthesiologists, 6 oncologists, and 9 nurses. As a result of a comprehensive review, 33 items were initially formed. Among them, the consensus was reached for 27 items after the first Delphi round. The other six items and a total of five items for supplementation entered the second round, among which consensus was reached for eight items and three items were excluded. Expert consensus was achieved on 35 items after two rounds of consultation, which involved the collection of patient basic information, comprehensive pain assessment, breakthrough or neuropathic pain assessment, analgesic treatment evaluation, out-of-hospital follow-up, medical records, and evidence-based documents for reference. Conclusion: The final list of 35 items could be used to develop the practice of pharmaceutical care for cancer pain management in outpatient clinics in China. The practice may aid in the standardization of pharmaceutical care for pain, relieve pain to the greatest extent possible, and enhance the level of pain management in China.
