Interstitial lung disease in patients treated with poly (ADP-ribose) polymerase inhibitors (PARPi): analysis of results from clinical trials and the FDA Adverse Events Reporting System database.

OBJECTIVE: To evaluate the risk of interstitial lung disease associated with poly (ADP-ribose) polymerase inhibitors (PARPi) and characterize its clinical features. METHODS: We systematically reviewed phase III randomized clinical trials of interstitial lung disease related to PARPi and calculated Peto odds ratios (ORs) with 95% confidence intervals (CIs). Pharmacovigilance studies were conducted by collecting cases of PARPi-related interstitial lung disease from the FDA Adverse Events Reporting System and assessing disproportionalities by reporting ORs and information components. RESULTS: A total of five randomized clinical trials involving 2980 patients were included. Although PARPi showed a tendency to increase the risk of interstitial lung disease compared with controls, this difference was not significant (Peto OR: 4.92; 95% CI: 0.92 to 26.35). A total of 170 cases of interstitial lung disease related to PARPi were included, with a median latency of 99 days. PARPi had a significantly increased reporting of interstitial lung disease (reporting OR: 2.86; 95% CI: 2.46 to 3.33; information component (IC): 1.49; 95% CI: 1.28 to 1.74). Our sensitivity analyses showed strong robustness of the disproportionalities between PARPi as a class, olaparib, and interstitial lung disease. Some 91.9% of patients experienced discontinuation, 51.6% achieved remission, and no deaths were reported. CONCLUSION: Our pharmacovigilance study suggested increased reporting of interstitial lung disease related to PARPi particularly olaparib.

Pulmonary tuberculosis associated with immune checkpoint inhibitors: a pharmacovigilance study.

We examined case reports of immune checkpoint inhibitors (ICIs) associated pulmonary tuberculosis (PT) using data from the Food and Drug Administration Adverse Event Reporting System database. Disproportionality analysis was performed by using the reporting OR (ROR) with relevant 95% CI. A total of 74 cases of PT related to ICIs therapy were identified. ICIs were significantly associated with over-reporting frequencies of PT (ROR=3.16, 95% CI: 2.51 to 3.98), while the signal was differed between anti-programmed death-1/ligand-1 and anti-cytotoxic T lymphocyte antigen-4 agents. Most indications were lung cancer (64.9%), the median onset age was 70 years, the median time to onset of PT was 70 days, ICIs were discontinued in most cases (85.2%).

Ileus in patients treated with immune checkpoint inhibitors: A retrospective, pharmacovigilance study using Food and Drug Administration Adverse Event Reporting System database.

OBJECTIVE: Immune checkpoint inhibitors (ICIs) have been widely used in cancer treatment; however, some case reports suggested that ICIs treatment might result in ileus. This study aims to comprehensively reveal the relationship between ileus and ICIs treatment in real-world cases from Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). METHODS: Reports from January 1, 2011 to December 31, 2020 were extracted from the FAERS. ICIs-related adverse events in patients were defined as related to use of anti-programmed cell death protein 1 antibodies (PD-1, nivolumab and pembrolizumab), anti-programmed cell death-ligand 1 inhibitors (PD-L1, atezolizumab, durvalumab, avelumab, and cemiplimab), and anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4, ipilimumab and tremelimumab). ICIs-related ileus cases were identified to characterize their clinical features. Reporting odds ratios (ROR) and information component (IC) were used to assess the relationship between ICIs and ileus. RESULTS: Among the 105 001 cases related to ICIs, 245 were reported with ICI-related ileus. The affected patients were mainly elderly (median age, 64.5 years) and male (58%, n = 143). The median onset for all cases was 36 (range 0-880) days, and no statistical difference was observed between monotherapy and combination therapy (PD-1 or PD-L1 plus CTLA-4) (p = 0.21). Most patients required drug withdrawal treatment (n = 113, 74%) and can achieve a recovered-resolved state (n = 72, 46%). All ICIs were significantly associated with ileus (ROR = 4.27, 95%Cl: 3.75-4.85; IC = 2.04, 95%Cl: 1.79-2.31). Ileus events were most commonly reported in PD-1 treatment (n = 164, ROR = 3.83, 95%Cl: 3.28-4.48; IC = 1.90, 95%Cl: 1.62-2.21). CONCLUSION: This pharmacovigilance database analysis suggested that ICIs are related to ileus. However, combination therapy may not speed up the onset of ileus.

Extensive serum biomarker analysis in patients with non-small-cell lung carcinoma.

Lung cancer is a common malignant disease, nearly 2.09 million new patients occurred last year. Approximately 85% of the patients are classified as non-small-cell lung cancer (NSCLC). It is therefore important to identify new diagnostic and prognostic biomarkers for the early detection of this disease. The presented study identifies biomarkers in the serum of NSCLC patients. The expression of 274 cytokines was measured by a novel antibody array methodology and ELISA was applied to validate the array results. The levels of MIP-1 α, IL-8, MIP-1 ß, Resistin, GDF-15, HGF, CA125, FLRG, VCAM-1, DKK-3, sTNF-R1, CTACK, Acrp30, CXCL-16 and LYVE-1 were significantly higher in serum from NSCLC patients, while the level of TIMP-2 and IGFBP-6 were lower. More importantly, the validation supported the result of the antibody array. The result of the antibody array indicates that these cytokines might be novel auxiliary biomarkers in the diagnosis and prognosis of NSCLC.

Risk of fatigue in cancer patients receiving anti-EGFR monoclonal antibodies: results from a systematic review and meta-analysis of randomized controlled trial.

BACKGROUND: To evaluate the association between fatigue and anti-epidermal growth factor receptor monoclonal antibodies (anti-EGFR MAbs), we conducted the first meta-analysis to access the incidence and risk of fatigue associated with anti-EGFR MAbs. METHODS: Electronic databases were searched for randomized controlled trials (RCTs) published up to February 2017. Eligible studies were selected according to PRISMA statement. Incidence rates, risk ratio (RRs), and 95% confidence intervals (CIs) were calculated using fixed-effects or random-effects models. Outcomes of quality were summarized in accordance with the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology. RESULTS: Thirty-five RCTs (including 15,622 patients) were included; median follow-up ranged from 8.1 to 71.4 months, and the fatigue events were recorded and graded according to the Common Toxicity Criteria for Adverse Events version 2.0 or 3.0 in most of the included trials. For patients receiving anti-EGFR MAbs, the overall incidence of all-grade and high-grade fatigue was 54.1% and 10.5%, respectively. Compared with control, anti-EGFR MAbs significantly increased the risk of all-grade fatigue (RR 1.10, 95% CI, 1.05-1.14, moderate-quality evidence) and high-grade fatigue (RR 1.31, 95% CI, 1.19-1.45, moderate-quality evidence). No significant differences among subgroup analyses (anti-EGFR MAbs, tumor type, and median follow-up) on high-grade fatigue were observed. No evidence of publication bias was observed. CONCLUSION: The present study suggested that anti-EGFR MAbs may increase the risk of fatigue in cancer patients.

Significance of Tumor-Infiltrating Lymphocytes and the Expression of Topoisomerase IIα in the Prediction of the Clinical Outcome of Patients with Triple-Negative Breast Cancer after Taxane-Anthracycline-Based Neoadjuvant Chemotherapy.

PURPOSE: The aim of this study was to determine factors able to predict chemotherapeutic responses and clinical outcomes in patients with triple-negative breast cancer (TNBC) after neoadjuvant chemotherapy (NAC). METHODS: Fifty-two TNBC patients on taxane-anthracycline-based NAC were included. The expression of Ki67, topoisomerase IIα (TOPOIIα), and p53, as well as the presence of CD4+ tumor-infiltrating lymphocytes (TILs) and CD8+ TILs were evaluated in biopsy specimens by immunohistochemistry. The expression of Ki67, TOPOIIα, and p53, as well as CD4 and CD8 in TILs was calculated according to the pathological response to NAC, disease-free survival (DFS), and overall survival (OS). RESULTS: Fourteen (26.9%) TNBC patients demonstrated a pathological complete response (pCR). According to univariate analyses, significant factors associated with pCR were high infiltration of CD4+ TILs (p = 0.004), high infiltration of CD8+ TILs (p = 0.010), and high expression of topoisomerase IIα (TOPOIIα) (p = 0.006). CD4+ TILs and TOPOIIα were significantly positively correlated with CD8+ TILs. Multivariate analyses indicated that TOPOIIα was an independent predictor of pCR. Although TNBC patients with high infiltration of CD4+ TILs, CD8+ TILs, or with high expression of TOPOIIα exhibited a significantly good 5-year DFS, only TNBC patients with a high infiltration of CD8+ TILs exhibited significantly positive 5-year OS probabilities. CONCLUSION: Our study demonstrated that CD4+ TILs and TOPOIIα in pretreated cancer tissues were significantly correlated with CD8+ TILs. CD4+ TILs, CD8+ TILs, and TOPOIIα expression were predictors of pCR and 5-year DFS of TNBC patients who were treated with NAC, and TOPOIIα was an independent predictor of pCR. CD8+ TILs were a key factor in the prediction of good 5-year OS rates of TNBC patients after taxane-anthracycline-based NAC.

Physiologically-Based Pharmacokinetic Modelling to Investigate the Effect of CYP3A4/3A5 Maturation on Tacrolimus Pharmacokinetics in Paediatric HSCT Patients.

Tacrolimus (FK506) is a cornerstone of GVHD-prophylaxis treatment in paediatrics undergoing haematopoietic stem cell transplantation (HSCT). However, due to concerns about highly inter/intra-individual variability, precision dosing of FK506 is crucial. Cytochrome P450(CYP) 3A4 and 3A5 are considered important sources of FK506 pharmacokinetic variability. Nevertheless, the impact of age-related maturation in hepatic and intestinal CYP3A4/3A5 enzymes remains unknown in paediatric HSCT patients. Physiologically-based pharmacokinetic (PBPK) models were developed and verified in adult volunteers and adult HSCT patients using GastroPlusTM (version 9.0), and then extrapolated to paediatric HSCT patients, taking into account the maturation of CYP3A4 and CYP3A5. Default CYP3A4 and CYP3A5 ontogeny profiles were updated based on the latest reports. The paediatric PBPK model was evaluated with independent data collected from Sun Yat-sen Memorial Hospital (86 paediatric HSCT patients, 1 to 16 -year-old). Simulations were performed to evaluate a reported FK506 dosing regimen in infants and children with different CYP3A5 genotypes. Extensive PBPK model validation indicated good predictability, with the predicted/observed (P/O) ratios within the range of 0.80-fold to 1.25-fold. Blood tacrolimus concentration-time curves were comparable between the real and virtual patients. Simulations showed that the higher levels of tacrolimus in 9-month-old to 3-year-old infants were mainly attributed to the CYP3A4/3A5 ontogeny profiles, which resulted in lower clearance and higher exposure relative to dose. The oral dosage of 0.1 mg/kg/day (q12 h) is considered appropriate for paediatric HSCT patients 9 months to 15 years of age with CYP3A5 *1/*1 genotypes. Lower doses were required for paediatric HSCT patients with CYP3A5 *1/*3 (0.08 mg/kg/day, q12h) or CYP3A5 *3/*3 genotypes (0.07 mg/kg/day, q12h), and analyses demonstrated 12.5%-20% decreases in ≤3-year-old patients. The study highlights the feasibility of PBPK modelling to explore age-related enzyme maturation in infants and children(≤3-year-old) undergoing HSCT and emphasizes the need to include hepatic and gut CYP3A4/3A5 maturation parameters.

Facial palsy induced by immune checkpoint blockade: A systematic analysis of clinical trials and a pharmacovigilance study of postmarketing data.

BACKGROUND: To estimate the risk of facial nerve palsy (FP) associated with immune checkpoint inhibitors (ICIs), and to describe its clinical features. METHODS: Data from randomized controlled trials (RCTs) and FDA Adverse Event Reporting System (FAERS) database were included. The primary outcome was the risk of FP events associated with ICIs. For data from RCTs, pooled analysis was performed by using risk ratios (RRs) with 95%CIs. In a separate retrospective pharmacovigilance study of FAERS, disproportionality was analyzed using the proportional reports reporting odds ratio (ROR) and information components (IC). RESULTS: A total of 21 RCTs (193,05 patients) were included, ICIs were associated with increased risk of FP (OR = 3.07, 95%CI:1.43-6.58). Results of subgroup analysis indicated that OR of ICI-related FP did not vary significantly by tumor type, ICIs treatment schedule, case of events, study design, median PFS and publication status. FAERS pharmacovigilance data identified 274 cases of FP related to ICIs therapy. ICIs were significantly associated with over-reporting frequencies of FP (ROR = 3.03, 95%CI:2.69-3.42; IC = 1.56, 95%CI:1.38-1.76). The median onset time of FP was 5.5 weeks, drug interruption was recorded in 78.0% of cases, with a positive dechallenge in 82.8 % of cases, and 71.7% of cases were recovered or recovering. CONCLUSIONS: These data suggest that ICIs were significantly associated with increased risk of FP in both trial settings and in clinical practice.

SGLT-2 inhibitors and euglycemic diabetic ketoacidosis/diabetic ketoacidosis in FAERS: a pharmacovigilance assessment.

AIMS: To investigate the main feature and the association between euglycemic diabetic ketoacidosis (euDKA) /diabetic ketoacidosis (DKA) and sodium-dependent glucose transporters 2 inhibitors (SGLT-2i) from the FDA adverse event reporting system (FAERS). METHODS: Cases of SGLT-2i-associated with euDKA/DKA were extracted from the FAERS database and compared with the reports for other hypoglycemia agents (ATC10 class). Disproportionality analyses used the reporting odds ratio (ROR) and information components (IC). The lower limit of the IC 95% credibility interval for IC > 0 is considered a reported signal, with at least 3 cases. RESULTS: A total of 10,195 cases of euDKA (n = 1680) and DKA (n = 8515) associated with SGLT-2i were identified from the FAERS. The SGLT-2i was associated with higher reporting of euDKA and DKA compared to other hypoglycemia agents (ROR = 16.69 [95% CI 14.89-18.70], IC = 3.27 [95% CI 2.91-3.66] for euDKA; ROR = 16.44 [95% CI 15.72-17.20], IC = 3.19 [95% CI 3.05-3.34] for DKA). In available data, the median onset time of euDKA/DKA was 31 days, and canagliflozin had the longest onset time (96.5 days for euDKA and 75 days for DKA) compared with dapagliflozin and empagliflozin (p < 0.05). Male patients predominate in euDKA (51.9%), and female patients predominate in DKA (53.7%). Most patients discontinue the treatment (95.5% for euDKA, 93.9% for DKA), and approximately 49.0% (n = 3658) of patients had symptomatic remission after discontinuation of SGLT-2i, and 2.3% (n = 173) of patients had no remission. About 75.6% (n = 6126) of patients need hospitalization after euDKA/DKA. CONCLUSIONS: Post-marketing data showed that SGLT-2i was significantly associated with higher reporting of euDKA/DKA. Although euDKA/DKA is rare, clinicians should be aware of SGLT-2i-associated euDKA/DKA events.

A pharmacovigilance analysis of FDA adverse event reporting system events for romosozumab.

BACKGROUND: Romosozumab is a novel drug for the treatment of osteoporosis. The adverse reactions of romosozumab still need to be explored. The FDA Adverse Event Reporting System (FAERS) provides an enormous dataset for adverse events (AEs) analysis. RESEARCH DESIGN AND METHODS: AEs registered in FAERS between January 2019 and December 2020 were collected for this study. The reporting odds ratio (ROR) method was applied to analyze the AEs of romosozumab. The number of AEs ≥4 cases and ROR value 95% confidence interval (CI) lower limit >1 was considered statistically significant. RESULTS: A total of 4,413,695 AEs were collected for this study. There were 1,948 AEs related with romosozumab reported in FAERS. There are 1851 AEs including 17 system classifications after filtered. Injection site pain (ROR = 6.89, CI = 5.60, 8.48), cardiac failure (ROR = 12.62, CI = 9.85, 16.17), renal impairment (ROR = 9.11, CI = 6.98, 11.89), pneumonia (ROR = 1.53, CI = 1.10, 2.21), blood alkaline phosphatase increased (ROR = 14.60, CI = 9.28, 22.97) were possible AEs after romosozumab application. CONCLUSIONS: Our study provides an adverse reaction warning for the clinical application of romosozumab and provides a real-world disproportionality analysis data support for the possible AEs of romosozumab.

Cost-effectiveness analysis of nivolumab plus cabozantinib versus sunitinib as first-line therapy in advanced renal cell carcinoma.

Aim: To evaluate the cost-effectiveness of first-line treatment for advanced renal cell carcinoma with nivolumab plus cabozantinib versus sunitinib from a US payer perspective. Methods: Economic outcomes were estimated with Markov and partitioned survival models. Efficacy, safety and other data were taken from the CheckMate 9ER trial. Costs and utilities were gathered from published sources. Sensitivity analyses addressed model uncertainties. Results: The incremental cost-effectiveness ratio of nivolumab plus cabozantinib versus sunitinib was US$555,663 and $531,748 per quality-adjusted life year in the Markov and partitioned survival models, respectively, exceeding the willingness-to-pay threshold (US$150,000 per quality-adjusted life-year). Sensitivity analyses showed robust outcomes. Conclusion: From a US payer perspective, first-line nivolumab plus cabozantinib for advanced renal cell carcinoma is not cost effective.

Renal cell carcinoma (RCC) is a common cancer in the USA. Up to 30% of patients with RCC are in an advanced stage of disease at diagnosis. RCC is difficult to cure, with an 11% chance of survival after 5 years for patients with advanced RCC. A recent clinical study showed that nivolumab plus cabozantinib (NC) had a greater benefit in patients with advanced RCC than sunitinib. The US FDA approved NC for advanced RCC, but NC is relatively expensive. This study explored the cost­effectiveness of NC for advanced RCC versus sunitinib for a US payer using two cost­effectiveness models developed based on the results of the aforementioned clinical study. The results showed that to gain an additional year in perfect health, NC costs an average of US$555,663 or $531,748 more versus sunitinib, which is more than a US payer is willing to pay for an additional year in perfect health ($150,000). Therefore, NC for advanced RCC is not cost-effective versus sunitinib for a US payer at current prices.

Type 1 diabetes with immune checkpoint inhibitors: A systematic analysis of clinical trials and a pharmacovigilance study of postmarketing data.

BACKGROUND: To estimate the risk of type 1 diabetes associated with immune checkpoint inhibitor (ICI-T1DM), and to describe its clinical features. METHODS: ICI-T1DM events in randomized clinical trials (RCTs) available in electronic databases were systematically reviewed. The primary outcome was the summary risk of T1DM related to ICIs, a meta-analysis was conducted to obtain Peto odds ratios (ORs) with 95 % CIs. In pharmacovigilance study, ICI-T1DM cases were extracted from FAERs. Disproportionality analyses were performed by calculating reporting odds ratio (ROR) and information components (IC). RESULTS: A total of 29 RCTs (20,234 patients) were included, treatment with ICIs significantly increased the risk of all-grade ICI-T1DM (OR: 4.54, 95 % CI: 2.66-7.72), and high-grade (grade 3 or above) ICI-T1DM (OR: 4.26, 95 % CI: 2.12-8.58). No significant differences among subgroup analyses were observed: ICIs treatment schedule, tumor type, case of events (T1DM vs F-T1DM), study design (double blind vs open label) or median PFS (PFS favours ICIs vs PFS favours Control). A total of 978 case reports form FAERS was extracted, treatment with ICIs significantly increased the reporting of ICI-T1DM (n = 978; ROR = 38.45, 95 %CI:35.70-41.41; IC = 4.77, 95 %CI:4.43-5.14). In cases with available data, the median latency period was 10.4 weeks, drug interruption was recorded in 82.3 % of cases, with a positive dechallenge in 76 % of cases, and death was recorded as outcome in 3.6 % of reports. CONCLUSIONS: Both data from clinical trials and postmarketing suggested that ICIs was associated with increased risk of ICI-T1DM. As ICIs gain greater clinical use, practitioners must be aware of ICI-T1DM events.

Population Pharmacokinetics and Initial Dosage Optimization of Tacrolimus in Pediatric Hematopoietic Stem Cell Transplant Patients.

Background: There is a substantial lack of tacrolimus pharmacokinetic information in pediatric hematopoietic stem cell transplant (HSCT) patients. This study aimed to develop population pharmacokinetics (PopPK) of tacrolimus in pediatric HSCT patients and to devise model-guided dosage regimens. Methods: A retrospective analysis was performed on 86 pediatric HSCT patients who received tacrolimus intravenously or orally. A total of 578 tacrolimus trough concentrations (C0) were available for pharmacokinetic analysis using a non-linear mixed-effects modeling method. Demographic and clinical data were included and assessed as covariates via the stepwise method. Bayesian estimators were used to devise pediatric dosage regimens that targeted C0 of 5-15 ng mL-1. Results: A one-compartment model with first-order absorption adequately described the tacrolimus pharmacokinetics. Clearance (CL), volume of distribution (V), and typical bioavailability (F) in this study were estimated to be 2.42 L h-1 (10.84%), 79.6 L (16.51%), and 19% (13.01%), respectively. Body weight, hematocrit, post-transplantation days, and caspofungin and azoles concomitant therapy were considered significant covariates for tacrolimus CL. Hematocrit had a significant impact on the V of tacrolimus. In the subgroup cohort of children (n = 24) with CYP3A5 genotype, the clearance was 1.38-fold higher in CYP3A5 expressers than in non-expressers. Simulation indicated that the initial dosage optimation of tacrolimus for intravenous and oral administration was recommended as 0.025 and 0.1 mg kg-1 d-1 (q12h), respectively. Conclusion: A PopPK model for tacrolimus in pediatric HSCT patients was developed, showing good predictive performance. Model-devised dosage regimens with trough tacrolimus concentrations provide a practical strategy for achieving the therapeutic range.

Global research trends of drug-induced liver injury (DILI) in the past two decades: a bibliometric and visualized study.

BACKGROUND: Drug-induced liver injury (DILI) has become one of the most common and serious adverse drug reactions owing to its high morbidity and leading cause of hepatic failures, which had attracted great attentions worldwide in the past two decades. A need therefore exists to conduct a bibliometric and visualized analysis of the global research trends on DILI with the aim of identifying the status of current research and prioritize the future research areas. METHODS: Publications related to DILI from 1999 to 2019 were extracted through an electronic search of the Web of Science (WoS) and PubMed databases. VOSviewer software was used to perform visualized analysis of bibliographic coupling, co-authorship, co-citation and co-occurrence, and to assess the global trends. RESULTS: Totally of 6,563 publications were identified based on the inclusion criteria. It is noted that the global trends of literatures on DILI showed a significant increase over time and more importantly predict the relevant publications will rise continuously in the coming decades. The United States led in terms of publication numbers with the most citations (the highest H-index). Hepatology made great contributions to the highest H-index and the most citations of publications. University of North Carolina was regarded as the most contributive institution. Notably, after conducting co-occurrence and cluster analysis of keywords and citation networks, it is shown that the pathogenesis, clinical manifestations, diagnosis and risk factors of this field will become the most prominent research hotspots. CONCLUSIONS: The mapping results provides global development trends of publications on DILI from 1999 to 2019. Future studies focused on the diagnosis and predisposing factors of this field will be encouraged.

Stevens-Johnson syndrome/toxic epidermal necrolysis in patients treated with immune checkpoint inhibitors: A safety analysis of clinical trials and FDA pharmacovigilance database.

BACKGROUND: The association between immune checkpoint inhibitors (ICIs) and Stevens-Johnsons syndrome (SJS) /toxic epidermal necrolysis (TEN) is unclear. We assessed the risk of SJS and TEN related to ICIs, via a systematic analysis of SJS/TEN cases reported in clinical trials and the FDA Adverse Event Reporting System (FAERS). METHODS: We explored ICIs related SJS/TEN events in randomized control trials available in ClinicalTrials.gov and electronic databases (Pubmed, Embase, the Cochrane Central Register of Controlled Trials) up to 12 January 2021. Meta-analysis was performed by using Peto odds ratios (ORs) with 95% CIs. In a separate retrospective pharmacovigilance study of FAERs, cases of ICIs related SJS/TEN were extracted between the first quarter (Q1) of 2004 and Q4 of 2020. Disproportionality was analyzed using the proportional reports reporting odds ratio (ROR) and information components (IC). PROSPERO registration number: CRD42021232399. FINDINGS: A total of 20 RCTs (11597 patients) were included. ICIs were associated with an increased risk of SJS/TEN (OR= 4.33, 95%CI:1.90-9.87). FAERS pharmacovigilance data identified 411 cases of SJS (n = 253) or TEN (n = 184) related to ICIs therapy. ICIs were significantly associated with SJS/TEN (n = 411; ROR=2.88, 95%CI:2.61-3.17; IC=1.49, 95%CI:1.35-1.65). The median onset time of SJS/TEN was 25.5 days (SJS:21.5 days; TEN:32 days) (n = 190), 97.5% of patients discontinued use of ICIs when suffering from SJS/TEN (n = 201). Of 305 cases that reported outcomes, 113 (37%) resulted in death (SJS:19.9%, TEN:61.6%). INTERPRETATION: These data suggest that ICIs were significantly associated with increased risk of SJS/TEN.

Risk of adverse events in lymphoma patients treated with brentuximab vedotin: a systematic review and meta-analysis.

Objectives: To assess the risk of adverse events (AEs) associated with brentuximab vedotin in lymphoma patients.Methods: Articles were retrieved from PubMed, Cochrane, and Clinicaltrials Databases to identify randomized controlled trials (RCTs) comparing brentuximab vedotin with non-brentuximab vedotin in lymphoma patients.Results: A total of 2225 patients from 4 RCTs were included. Compared with the non-brentuximab vedotin group, the brentuximab vedotin group significantly increased the risk of all-grade AEs (RR 1.05, 95% CI: 1.00-1.10), and high-grade AEs (risk ratio [RR] 1.27, 95% confidence intervals [CI]: 1.01-1.58). The brentuximab vedotin group significantly increased the risk of all-grade peripheral sensory neuropathy (RR 2.29, 95% CI: 1.23-4.26), pyrexia (RR 1.23, 95% CI: 1.05-1.44), nausea (RR 1.51, 95% CI: 1.05-2.18), vomiting (RR 1.54, 95% CI: 1.08-2.19), diarrhea (RR 1.69, 95% CI: 1.44-1.98), and alopecia (RR 1.18, 95% CI: 1.00-1.39), respectively. The brentuximab vedotin group significantly increased the risk of high-grade sensory neuropathy (RR 4.79, 95% CI: 1.46-15.75), neutropenia (RR 1.48, 95% CI: 1.01-2.18), nausea (RR 2.65, 95% CI: 1.37-5.12), vomiting (RR 2.2, 95% CI: 1.17-4.12), and diarrhea (RR 1.85, 95% CI: 1.21-2.85).Conclusion: Brentuximab vedotin increased the risk of certain AEs in lymphoma patients.

Association of glucose-lowering medications with cardiovascular outcomes: an umbrella review and evidence map.

BACKGROUND: Considering the global burden of diabetes and associated cardiovascular disease, an urgent need exists for the best treatment, which should be based on the best available evidence. We examined the association between glucose-lowering medications and a broad range of cardiovascular outcomes, and assessed the strength of evidence for these associations. METHODS: For this umbrella review we searched PubMed, Embase, and the Cochrane Library to identify systematic reviews and meta-analyses of randomised controlled trials examining the cardiovascular safety of glucose-lowering medications. Cardiovascular outcomes examined included major adverse cardiovascular events, cardiovascular death, myocardial infarction, stroke, heart failure, unstable angina, and atrial fibrillation. For each meta-analysis, we estimated the relative risk (RR) and 95% CI. We also created an evidence map showing the plausible benefits or harms of each intervention and the certainty of the evidence. FINDINGS: We examined 232 meta-analyses evaluating ten classes of diabetes drugs. We identified six risk and 38 protective associations showing a high strength of evidence. Six associations increased the risk of cardiovascular disease, including glimepiride (stroke [RR 2·01; 95% CI 1·02-3·98]), rosiglitazone (myocardial infarction [1·28; 1·02-1·62] and heart failure [1·72, 1·31-2·27]), and pioglitazone (heart failure [1·40; 1·16-1·69]). 38 associations decreased the risk of cardiovascular disease, including glucagon-like peptide-1 receptor agonists as a class (major adverse cardiovascular events [RR 0·88; 95% CI 0·84-0·92], death from cardiovascular disease [0·87; 0·81-0·94], myocardial infarction [0·92; 0·86-0·99], stroke [0·84; 0·77-0·93], and heart failure [0·90; 0·83-0·99]), albiglutide (major adverse cardiovascular events [0·81; 0·68-0·96], myocardial infarction [0·77; 0·64-0·92], and heart failure [0·71; 0·55-0·93]), dulaglutide (stroke [0·78; 0·64-0·96]), exenatide (major adverse cardiovascular events [0·91; 0·83-1·00]), liraglutide (major adverse cardiovascular events [0·86; 0·77-0·96]), semaglutide (major adverse cardiovascular events [0·76; 0·62-0·92] and stroke [0·67; 0·45-1·00]), sodium-glucose co-transporter-2 inhibitors as a class (major adverse cardiovascular events [0·87; 0·82-0·93], death from cardiovascular disease [0·82; 0·75-0·90], myocardial infarction [0·86; 0·78-0·94], and heart failure [0·68; 0·63-0·73]), canagliflozin (major adverse cardiovascular events [0·84; 0·75-0·93], death from cardiovascular disease [0·82; 0·71-0·96], and heart failure [0·65; 0·54-0·78]), dapagliflozin (heart failure [0·70; 0·60-0·82]), empagliflozin (major adverse cardiovascular events [0·85; 0·77-0·94], death from cardiovascular disease [0·62; 0·50-0·78], and heart failure [0·64; 0·53-0·77]), and pioglitazone (major adverse cardiovascular events [0·84; 0·74-0·96], myocardial infarction [0·80; 0·67-0·95], and stroke [0·79; 0·65-0·95]). INTERPRETATION: We found varied levels of evidence for the associations between diabetes drugs and cardiovascular outcomes; some drugs raised the risk of cardiovascular disease, whereas others showed benefit. FUNDING: None.

Developing an isotope dilution UHPLC-MS/MS method to quantify linezolid in human plasma: application to therapeutic drug monitoring.

Aim: To optimize clinical efficacy and reduce the drug-exposure-related toxicity of linezolid, whose concentrations show wide inter-variabilities, a simple and reliable quantitative assay for therapeutic drug monitoring is necessary. Results: A UHPLC-MS/MS assay has been established for determination of linezolid in human plasma and fully validated according to the US FDA guidelines. After a simple, isotope-dilluted precipitation with methanol, the analytes were separated by a straightforward isocratic mode and the MS/MS was conducted under the ESI+ mode fitted with SRM. The calibration curves proved acceptable linearity in the range of 0.1-30.0 µg/ml. Conclusion: The present assay is currently used in routine clinical practice, being applied to therapeutic drug monitoring and helps to optimize individual dosing regimens and manage adverse effects in ICU patients.

Toxicity profile characteristics of novel androgen-deprivation therapy agents in patients with prostate cancer: a meta-analysis.

BACKGROUND: To investigate the toxicity profile characteristics of abiraterone acetate and enzalutamide to see if they are of critical clinical value. METHODS: Prospective studies were identified by searching the PubMed, EMBASE, Cochrane Library, and American Society of Clinical Oncology Meeting abstracts. Randomized clinical trials that evaluate abiraterone acetate or enzalutamide in patients with prostate cancer were included. The risk ratio (RR) of adverse events (AEs) was calculated for each trial along with appropriate 95% CI using fixed- or random-effects methods. RESULTS: Ten studies (5 abiraterone acetate, and 5 enzalutamide studies) were included in the meta-analysis. Use of abiraterone acetate was associated with an increased risk of all-grade adverse effects (RR = 1.01, 95% CI: 1.01-1.02) and high-grade adverse effects (RR = 1.29, 95% CI: 1.15-1.45). Also, there was a significantly higher incidence of some individual adverse effects (e.g. liver-function test abnormalities, arthralgia, cardiac adverse effects, diarrhea, oedema, hypertension and hypokalemia). Treatment with enzalutamide did not increase the risk of all-grade adverse effects and high-grade adverse effects, but there was a significantly higher incidence of some individual adverse effects (e.g. back pain, fatigue, hot flush and hypertension). CONCLUSIONS: Both abiraterone acetate and enzalutamide have toxicity profile characteristics that need to be recognized. Understanding the toxicity profile characteristics of both drugs could promote decision making in clinical use.
