RESUMEN
Anti-human epidermal growth factor receptor 2 (HER2) agents have exhibited pronounced tumor-inhibitory activity, yet the accompanying ocular toxicity has frequently been underestimated. We aim to conduct a comprehensive comparative analysis of ocular toxicity risk related to various anti-HER2 agents. We executed a retrospective pharmacovigilance investigation based on the FDA Adverse Event Reporting System (FAERS) database, covering the period from Q2 2018 to Q1 2023. The disproportionality analysis was performed to assess ocular toxicity risk. Multivariate logistic regression was implemented to mitigate potential biases. Moreover, the time to onset of ocular toxicity was also evaluated. A total of 3467 ocular adverse event (AE) reports concerning anti-HER2 agents were collected. At the preferred term (PT) level, there were 69 positive signals, among which excessive eye blinking, abnormal sensation in the eye, and asthenopia presented a significant risk. In comparison to tyrosine kinase inhibitors (TKIs), antibody drugs were associated with a broader range of ocular disorders at Standardized MedDRA Queries (SMQ)levels, including conjunctival disorders, corneal disorders, ocular infections, ocular motility disorders, optic nerve disorders, and retinal disorders. In terms of onset time, pertuzumab displayed an earlier onset at 21.5 days, while trastuzumab deruxtecan had the latest at 91.5 days. In summary, our study reveals varying degrees of ocular toxicity related to anti-HER2 agents, with a significantly higher risk observed in antibody drugs. Additionally, novel ocular toxicity signals, not documented in product labels, have been detected. In the future, further research will be necessary to validate our findings.

Person-generated health data (PGHD) are valuable for studying outcomes relevant to everyday living, for obtaining information not otherwise available, for long-term follow-up, and in situations where decisions cannot wait for traditional clinical research to be completed. While there is no dispute that these data are subject to bias, insights gained may be better than having an information void, provided the biases are understood and addressed. People will share information known uniquely to them about exposures that may affect drug tolerance, safety, and effectiveness (eg, nonprescription and complementary medications, alcohol, tobacco, illicit drugs, exercise, etc). Patients may be the best source of safety information when long-term follow-up is needed (eg, the 5- to 15-year follow-up required for some gene therapies). Validation studies must be performed to evaluate what people can accurately report and when supplementary confirmation information is needed. However, PGHD has already proven valuable in quantifying and contrasting COVID-19 vaccine benefits and risks and for evaluating disease transmission and the accuracy of COVID-19 testing. Going forward, PGHD will be used for patient-measured and patient-relevant outcomes, including for regulatory purposes, and will be linked to broader health data networks using tokenization, becoming a mainstay for signals about risks and benefits for diverse populations. This article is part of a Special Collection on Pharmacoepidemiology.

BACKGROUND: Establishing whether there is a potential relationship between glucagon-like peptide 1 receptor agonists (GLP-1RAs) and suicidal or self-injurious behaviors (SSIBs) is crucial for public safety. This study investigated the potential association between GLP-1RAs and SSIBs by exploring the FDA Adverse Event Reporting System (FAERS) database. METHODS: A disproportionality analysis was conducted using post-marketing data from the FAERS repository (2018 Q1 to 2022 Q4). SSIB cases associated with GLP-1RAs were identified and analyzed through disproportionality analysis using the information component. The parametric distribution with a goodness-of-fit test was employed to analyze the time-to-onset, and the Ω shrinkage was used to evaluate the potential effect of co-medication on the occurrence of SSIBs. RESULTS: In total, 204 cases of SSIBs associated with GLP-1RAs, including semaglutide, liraglutide, dulaglutide, exenatide, and albiglutide, were identified in the FAERS database. Time-of-onset analysis revealed no consistent mechanism for the latency of SSIBs in patients receiving GLP-1RAs. The disproportionality analysis did not indicate an association between GLP-1RAs and SSIBs. Co-medication analysis revealed 81 cases with antidepressants, antipsychotics, and benzodiazepines, which may be proxies of mental health comorbidities. CONCLUSIONS: We found no signal of disproportionate reporting of an association between GLP-1RA use and SSIBs. Clinicians need to maintain heightened vigilance on patients premedicated with neuropsychotropic drugs. This contributes to the greater acceptance of GLP-1RAs in patients with type 2 diabetes mellitus or obesity.

OBJECTIVE: To investigate the safety and efficacy of subcutaneous tocilizumab (SC-TCZ) treatment in a long-term extension (LTE) of clinical trials in polyarticular or systemic juvenile idiopathic arthritis (pJIA or sJIA). METHODS: Patients with pJIA or sJIA from two open-label, 52-week phase 1b core trials of SC-TCZ who had adequate response per investigator assessment entered the LTE and continued SC-TCZ treatment according to body weight-based dosing regimens until commercial availability or up to 5 years. Pharmacokinetics, pharmacodynamics, and efficacy were assessed for up to 3 years, and safety for up to 5 years in the LTE. RESULTS: Forty-four patients with pJIA and 38 patients with sJIA entered the LTE. Tocilizumab trough concentrations were maintained within the range expected to provide clinical benefit (mean values: pJIA, â¼10 µg/ml; sJIA, â¼75 µg/ml over 3 years). Pharmacodynamic parameters (interleukin-6, soluble interleukin-6 receptor, erythrocyte sedimentation rate, C-reactive protein) were maintained throughout the LTE at levels achieved in the core trials. Inactive disease per American College of Rheumatology provisional criteria was reported for 90% (17/19) and 53% (8/15) of patients with pJIA and 91% (10/11) and 92% (12/13) of patients with sJIA in the <30 and ≥30 kg body weight groups, respectively. Serious adverse events in the LTE were reported in six patients with pJIA (13.6%; five serious infections) and five patients with sJIA (13.2%; one serious infection). CONCLUSION: Patients with pJIA or sJIA experienced long-term disease control with SC-TCZ treatment. Long-term safety was consistent with the known tocilizumab safety profile. CLINICAL TRIAL REGISTRATION: clinicaltrials.gov, NCT02165345.

MET exon 14 skipping alterations and MET amplifications are recognized as oncogenic and targetable genetic changes in cancer patients. The treatment of MET-selective tyrosine kinase inhibitors (TKIs) in this specific population has shown encouraging therapeutic results. However, a comprehensive understanding of the potential toxicities linked to these agents is still lacking. The present pharmacovigilance analysis was carried out using the FDA Adverse Event Reporting System database to assess notable adverse events associated with MET-selective TKIs. Gastrointestinal disorders, respiratory toxicity, hepatotoxicity, and disturbances in metabolism and nutrition demonstrated a substantial prevalence and significance among the adverse event (AE) categories. Particularly notable were the occurrences of peripheral oedema, nausea, dysphagia, fatigue, and dyspnoea, which emerged as the foremost five reported AEs. The majority of these AEs were observed within the initial months of initiating treatment with MET-selective TKIs and persistently thereafter. Notably, our investigation unveiled a significant correlation between the usage of capmatinib and the incidence of hearing loss and difficulty in swallowing. Diligent monitoring and the implementation of supportive care strategies are essential in managing the toxicities associated with MET-selective TKIs, particularly those related to gastrointestinal disorders, respiratory toxicity, hepatotoxicity, and ototoxicity.

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.

Concerns persist about venetoclax's long-term safety in larger populations, with limited evidence of infrequent and delayed adverse events (AEs). The study integrated safety data on venetoclax in leukemia patients from randomized controlled trials (RCTs) and FDA adverse event monitoring system (FAERS). We systematically reviewed RCTs reporting safety outcomes of venetoclax in adult leukemia patients of any gender, either monotherapy or in combination, applying advanced search on databases like PubMed, EMBASE, and ClinicalTrial.gov. The quality assessment was done using the Cochrane Risk of Bias Tool. We utilized a random effect meta-analysis to calculate risk ratio (RR) with 95% confidence intervals (CI). The Open Vigil 2.1 MedDRAv24 was used to search the FAERS database, with data available until September 2023. The disproportionality was calculated using the proportional reporting ratio and the reporting odds ratio. The study protocol for meta-analysis was registered with PROSPERO; CRD42022378006. For the safety meta-analysis, seven RCTs with available AEs were examined. A total of 942 AEs were found associated with the venetoclax group; 79% of them were in grade three or above. Venetoclax significantly increased the risk of neutropenia grade three or above (RR = 1.34, 95% CI: 1.10-1.64, p: 0.0033) compared with the control group. In FAERS, 26,436 patients were reported with AEs associated with venetoclax. Significant signal scores were observed in hematological, cardiac, vascular, and gastrointestinal disorders. 11 out of 30 generated signals, failed to meet the signal criteria upon refinement. The current study updated and improved the safety profile of venetoclax in the post-marketing period, assisting in risk evaluation and mitigation for the best possible patient health care.

Histone deacetylase (HDAC) inhibitors are emerging as promising treatments for hematological malignancies, with potential applications extending to solid tumors in the future. Given their wide-ranging biological effects, there is a pressing need for a thorough understanding of the toxicities linked to HDAC inhibition. In this study, a pharmacovigilance analysis was conducted using the FDA Adverse Event Reporting System database. Suspected adverse events linked to HDAC inhibitors were detected through various statistical methodologies, including reporting odds ratio, proportional reporting ratio, information component, and Empirical Bayes Geometric Mean. Our study findings have illuminated that, among the total reported cases examined, gastrointestinal disorders accounted for 13% patients of the cohort, while lymphatic system disorders comprised 8% cases of the cohort, all of which manifested as adverse events induced by HDAC inhibitors. Importantly, the usage of HDAC inhibitors was found to be associated with incidents of atrial fibrillation, heart failure, respiratory failure, hepatic dysfunction, and acute kidney injury. Romidepsin and belinostat demonstrated more pronounced signals of adverse events compared to panobinostat and vorinostat, emphasizing the need for vigilant monitoring of adverse events in this particular population. Furthermore, atrial fibrillation (clinical priority score of 7 points) emerged as the paramount medical event warranting utmost clinical attention. Eventually, multiple adverse events were observe to emerge within the initial and second months following the initiation of treatment. Vigilant monitoring and supportive care strategies are critical in addressing the toxicities associated with HDAC inhibitors, particularly those concerning cardiotoxicity, respiratory toxicity, renal toxicity, and hepatotoxicity.

OBJECTIVE: This study was undertaken to assess the utility of the Ages and Stages Questionnaire-3rd Edition (ASQ-3) and the Vineland Adaptive Behavior Scales-2nd Edition (VABS-II) as neurodevelopmental screening tools for infants exposed to antiseizure medications in utero, and to examine their suitability for use in large-population signal generation initiatives. METHODS: Participants were women with epilepsy who were recruited from 21 hospitals in England and Northern Ireland during pregnancy between 2014 and 2016. Offspring were assessed at 24 months old using the Bayley Scales of Infant Development-3rd Edition (BSID-III), the VABS-II, and the ASQ-3 (n = 223). The sensitivity and specificity of the ASQ-3 and VABS-II to identify developmental delay at 24 months were examined, using the BSID-III to define cases. RESULTS: The ASQ-3 identified 65 children (29.1%) as at risk of developmental delay at 24 months using standard referral criteria. Using a categorical approach and standard referral criteria to identify delay in the ASQ-3 and BSID-III at 24 months, the ASQ-3 showed excellent sensitivity (90.9%) and moderate specificity (74.1%). Utilizing different cut-points resulted in improved properties and may be preferred in certain contexts. The VABS-II exhibited the strongest psychometric properties when borderline impairment (>1 SD below the mean) was compared to BSID-III referral data (sensitivity = 100.0%, specificity = 96.6%). SIGNIFICANCE: Both the ASQ-3 and VABS-II have good psychometric properties in a sample of children exposed to antiseizure medications when the purpose is the identification of at-risk groups. These findings identify the ASQ-3 as a measure that could be used effectively as part of a tiered surveillance system for teratogenic exposure by identifying a subset of individuals for more detailed investigations. Although the VABS-II has excellent psychometric properties, it is more labor-intensive for both the research team and participants and is available in fewer languages than the ASQ-3.

Clozapine is a second-generation antipsychotic drug that offers superior treatment results in patients with schizophrenia but is also associated with significant risks. This study analyzes data on pharmacotherapy with clozapine and the associated adverse drug reactions (ADRs) in an inpatient setting including 38,349 patients. Data about the use of clozapine and reports of severe ADRs within the period 1993-2016 were obtained from the multicentered observational pharmacovigilance program "Arzneimittelsicherheit in der Psychiatrie" (AMSP). In total, 586 severe clozapine-associated ADRs were documented (1.53% of all patients exposed). Patients aged ≥65 years had a higher risk of ADRs than patients aged <65 years (1.96 vs. 1.48%; p = 0.021). Significantly more ADRs were attributed to clozapine alone (396; 67.6% of all 586 ADRs) than to a combination with other drugs. The most frequent ADRs were grand mal seizures (0.183% of all 38,349 patients exposed), delirium (0.180%), increased liver enzymes (0.120%), and agranulocytosis (0.107%). We detected 24 cases (0.063%) of clozapine-induced extrapyramidal symptoms, of which 8 (0.021%) were attributed to clozapine alone. Five ADRs resulted in death (0.013%): 2 due to agranulocytosis (41 cases total) (mortality = 4.88%) and 3 due to paralytic (sub)ileus (16 cases) (mortality = 18.75%). The median dose of clozapine in all patients treated was 300 mg/day, in patients who developed ADRs 250 mg/day. The main risk factor for an ADR was pre-existing damage of the affected organ system. Overall, the results of this study highlight the importance of alertness-especially of frequently overlooked symptoms-and appropriate monitoring during treatment with clozapine, even at low doses.

BACKGROUND: Niraparib plays a crucial role in the treatment of ovarian cancer. A comprehensive understanding of the incidence and risk of hypertension associated with niraparib would be of vital importance to healthcare practitioners. METHODS: In this study, an observational, retrospective, pharmacovigilance study was conducted based on the FDA Adverse Event Reporting System (FAERS) database. Cases of hypertension related to niraparib were extracted for disproportionality analysis from the first quarter (Q1) of 2017 to Q1 of 2023. Moreover, a separate meta-analysis was performed using the randomized controlled trials (RCTs) on niraparib for cancer treatment published in PubMed, Embase, and Web of Science from inception to May 31st, 2023. The primary outcomes were the incidence and risk of hypertension associated with niraparib. RESULTS: In the FAERS, 1196 hypertension cases were found to be related to niraparib treatment. Notably, niraparib exhibited the highest level of disproportionality, as indicated by a reporting odds ratio (ROR) of 2.85 (95% CI, 2.69-3.01), suggesting a greater likelihood of causing hypertension compared to other poly-ADP-ribose polymerase (PARP) inhibitors (P < 0.01). Our safety meta-analysis included five pivotal RCTs of niraparib that reported hypertension. In comparison to placebo treatment, the meta-analysis demonstrated a significant increase in the risk of hypertension with niraparib (OR 2.84 [95% CI, 2.17-3.72], P < 0.01), with no heterogeneity observed among the studies (I2 = 0%, χ2 = 2.02, P = 0.73). The incidence of niraparib-induced hypertension was determined to be 16.9% (95% CI, 14.9-18.9; I2 = 34%). CONCLUSIONS: These findings suggest that hypertension is a distinctive adverse event associated with niraparib compared to other PARP inhibitors. Niraparib significantly increases the risk of hypertension that needs early recognition and management in clinical medication.

BACKGROUND: Data on drug-induced reversible cerebral vasoconstriction syndrome (RCVS) are scarce. We aimed to describe RCVS characteristics with drugs previously identified as associated with RCVS and investigate potential signals related to other drugs. METHODS: VigiBase® was queried for all reports of RCVS until 31 May 2023. A descriptive study was performed on reports concerning drug classes known to precipitate RCVS. To identify new drugs, a disproportionality analysis was conducted. RESULTS: In total, 560 reports were included. RCVS occurred in patients aged between 45-64 years (40%) and 18-44 years (35%), mainly in females (72.5%). Drugs were antidepressants (38.4%), triptans (6.4%), nasal decongestants (3.7%) and immunosupressants (8.7%). In 50 cases, antidepressants were in association with drugs known to precipitate RCVS. The median time to onset was 195 days for antidepressants and much shorter (1-10 days) for triptans, nasal decongestants and immunosuppressants. The outcome was favorable in 87% of cases, and fatal in 4.4%. We found a disproportionality signal with 14 drugs: glucocorticoids, bupropion, varenicline, mycophenolic acid, aripiprazole, trazodone, monoclonal antibodies (erenumab, ustekinumab and tocilizumab), leuprorelin and anastrozole. CONCLUSIONS: The present study confirms the role of vasoconstrictors in the onset of RCVS, particularly when used in combination and found potential signals, which may help clinicians envisage an iatrogenic etiology of RCVS.

The rise of immuno-oncology, including the use of chimeric antigen receptor T-cell (CAR-T) therapy is bringing in a new wave of cancer treatments, particularly in hematologic malignancies. However, data on their adverse events, particularly of the eye, is under-reported. To assess the ocular adverse events associated with the six FDA-approved CAR-T cell therapies, a disproportionality analysis utilizing the FAERS database was conducted from the first quarter of 2017 to the third quarter of 2023, as well as a systematic review of case reports of ocular events following CAR-T cell therapy up to December 20, 2023. A total of 53 ocular adverse events were identified from the FDAs FAERS database. The adverse events most frequently observed were mydriasis and xerophthalmia with tisagenlecleucel (Kymriah). The systematic review resulted in 8 case reports encompassing 19 patients which included a total of 27 events. This study demonstrates the importance of anticipation of potential ocular adverse events by ophthalmologists and oncologists as they can greatly contribute to morbidity in patients with cancer.

Due to the insufficiency of safety assessments of clinical trials for drugs, further assessments are required for post-marketed drugs. In addition to adverse drug reactions (ADRs) induced by one drug, drug-drug interaction (DDI)-induced ADR should also be investigated. The spontaneous reporting system (SRS) is a powerful tool for evaluating the safety of drugs continually. In this study, we propose a novel Bayesian method for detecting potential DDIs in a database collected by the SRS. By applying a power prior, the proposed method can borrow information from similar drugs for a drug assessed DDI to increase sensitivity of detection. The proposed method can also adjust the amount of the information borrowed by tuning the parameters in power prior. In the simulation study, we demonstrate the aforementioned increase in sensitivity. Depending on the scenarios, approximately 20 points of sensitivity of the proposed method increase from an existing method to a maximum. We also indicate the possibility of early detection of potential DDIs by the proposed method through analysis of the database shared by the Food and Drug Administration. In conclusion, the proposed method has a higher sensitivity and a novel criterion to detect potential DDIs early, provided similar drugs have similar observed-expected ratios to the drug under assessment.

AIMS: Neonates hospitalized in neonatal intensive care units (NICUs) commonly experience adverse drug reactions (ADRs). Thus, we aimed to develop and validate a tool for predicting ADRs in neonates hospitalized in NICUs. METHODS: A nested case-control study in an open cohort with neonates admitted to the NICU of a maternity hospital in Natal, Brazil was conducted from January 2019 to January 2022 [Correction added on 4 December 2023, after first online publication: 2023 has been changed to 2019 in the preceding sentence.]. Neonates with ADR were randomly paired with 2 controls. For the development of the tool, a multivariate logistic regression was applied on 2/3 of the sample (cases with respective controls). The model's fit was evaluated using the Hosmer-Lemeshow test for calibration and the Brier score for performance assessment. Validation of the tool was performed by determining the area under the receiver operating characteristic curve with bootstrap adjusted c-statistics. RESULTS: In all, 450 neonates (150 cases and 300 controls) were included in the study. We identified 5 independent risk factors for ADR, 4 related to the neonate (current mechanical ventilation, heart rate ≥178 beats/min, intravenous medications, ≥5 prescription medications) and 1 to the mother (gestational hypertension). The tool had a classification cut-off point of ≥15, and its total score ranged from 0 to 34. In validation, the tool had an area under the receiver operating characteristic curve of 0.74 (95% confidence interval [CI] 0.66-0.81) with sensitivity of 52.02% (95% CI 47.40-56.64) and specificity of 81.35% (95% CI 77.75-84.95). CONCLUSION: The tool demonstrated adequate discriminative ability and utilized 5 commonly monitored variables in the NICU.

Thirst is a complex physiological compensatory mechanism but could also be associated with drugs. This association was poorly investigated previously. Using the WHO global pharmacovigilance database, Vigibase®, disproportionality analyses potential associations between exposure to drugs and thirst reports were performed. All reports of thirst in adults between 01/01/2000 and 31/12/2023 were included. Results are expressed as reporting odds ratio (ROR). Analysis of the 3186 reports of thirst (978 'serious') allowed, first, to confirm the association between thirst and exposure to vasopressin antagonists (tolvaptan), lithium, gliflozins (dapagliflozin, empagliflozin), pregabalin and antimuscarinic drugs (glycopyronium, oxybutynin, tiotropium). Second, new safety signals were described with monoamine reuptake inhibitors (antidepressants: duloxetine, venlafaxine; anti-obesity agent: sibutramine), antipsychotic (olanzapine), glucocorticoid (prednisolone), diuretic (furosemide) drugs as well with ribavirin or sodium oxybate. This study is the first to offer a list of drugs associated with thirst in humans.

To our knowledge, no prior study has analysed a possible association between acetazolamide and pulmonary oedema. The aim of this study was to use data from the EudraVigilance to detect a safety signal for acetazolamide-induced pulmonary oedema. We performed a disproportionality analysis (case-noncase method), calculating reporting odds ratios (RORs) up to 22 February 2024. Among 11 684 208 spontaneous cases of adverse reactions registered in EudraVigilance, 38 275 were pulmonary oedemas. Acetazolamide was involved in 31 cases. In more than half of those cases, the patients received a single dose of acetazolamide after undergoing cataract surgery: latency was 10-90 min. Remarkably, there were five cases of positive rechallenge and six cases resulted in death. The ROR for acetazolamide was 3.63 (95% CI 2.55-5.17). Disproportionality was also observed in VigiBase®: ROR 4.44 (95% CI 3.34-5.90). Our study confirms a signal that suggests a risk of serious pulmonary oedema associated with acetazolamide.

AIMS: To assess the extent of off-label drug use and the occurrence of suspected adverse drug reactions (ADRs) among paediatric patients in Italian hospitals. METHODS: We conducted a 2-year prospective cohort study across 22 Italian hospital wards from September 2020 to September 2022. As part of the surveillance project, we performed a 6-month retrieval of all reported ADRs and evaluated all drug prescriptions for their possible off-label use. Following an educational project on pharmacovigilance addressed to healthcare professionals in participating wards, the same data collection was performed. RESULTS: Among the 892 patients included in the study, 64% were admitted to paediatric wards and 36% to neonatal wards. Fifty per cent of all drugs prescribed were used off-label and mainly concerned the administration of a different dose from the one authorized. In neonatal wards, off-label prescriptions occurred slightly more often, with antibacterials being the most frequently used off-label drugs. A total of 35 reports of suspected ADRs were collected, five before the educational project and 30 afterwards. Based on product licence, 10 of the total 35 reports concerned at least one off-label drug use. CONCLUSIONS: The off-label use of drugs in treating paediatric patients was extensive in Italian hospitals. Regulatory interventions are needed to promote the use of drugs based on the latest available literature and improve ADR reporting on children. Paediatric indications and dosages of the drugs most commonly used in children should be supported by appropriate ad hoc studies.

Globally, more than 200 million women become pregnant each year, most of whom receive medications despite limited information on their safe use during pregnancy. The paucity of drug safety data on pregnant and breastfeeding women stems from the routine exclusion of this population from clinical trials due to scientific, ethical, regulatory and legal concerns. Consequently, at the time of initial drug approval, there may be scant safety data to inform the drug benefit-risk balance to the mother, foetus or infant. Although momentum is growing to include this underrepresented population in clinical trials, most information on drug exposure outcomes comes from data collected in the postmarketing setting. Regulatory guidance and legislation on medication use in pregnancy and breastfeeding were reviewed globally by the TransCelerate IGR PV Pregnancy and Breastfeeding Team. The International Conference of Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) standards and Council for International Organizations of Medical Sciences guidelines served as benchmarks for national safety regulations and guidance. The landscape assessment identified a lack of harmonization of global regulations on research in pregnant and breastfeeding women and a lack of specific regulations on this topic in the majority of the territories included in the assessment. This article focuses on the ambiguities and lack of harmonization in global regulations on postmarketing pregnancy and breastfeeding safety studies. There is currently no ICH standard to guide these types of safety studies and, in most regions reviewed, there are no clear regulations or guidance on when and how to conduct them. While a challenging undertaking, greater clarity and harmonization would facilitate more timely completion of postmarketing pregnancy safety studies that would ultimately generate the critical data needed to optimize benefit-risk decisions for women who may conceive, as well as pregnant and breastfeeding women.

AIMS: Gabapentin and pregabalin bind to α2-δ subunit of voltage-gated calcium channels (Cav ). Other drugs targeting Cav include cardiovascular calcium channel blockers (CCBs) and anticonvulsants (levetiracetam, ethosuximide and zonisamide). In addition to pharmacodynamics, the safety profile of gabapentinoids seems to overlap with the one of cardiovascular CCBs (oedema) and Cav -blocking anticonvulsants (suicide and ataxia). The objective of this study was to cluster the safety profile of different Cav -ligand drugs by focusing on whether gabapentinoids present a distinct adverse drug reaction (ADR) signature from cardiovascular CCBs and anticonvulsants. METHODS: We extracted all ADRs with at least one significant disproportionate reporting (reporting odds ratio) related to gabapentinoids, CCBs or anticonvulsants in VigiBase. After principal component analysis preprocessing, a hierarchical ascendent classification was performed to cluster gabapentinoids and other Cav -ligand drugs that share a similar ADR signature. The robustness of the results was determined through four sensitivity analyses, varying on the dataset or the clustering method. RESULTS: A total of 16 drugs and 65 ADRs were included. Gabapentinoids were in Cluster #1, which included eight other drugs (isradipine, nicardipine, lacidipine, lercanidipine, ethosuximide, levetiracetam, zonisamide and nimodipine). Cluster #2 contained two drugs (diltiazem and verapamil) and Cluster #3 contained four drugs (amlodipine, felodipine, nifedipine and nitrendipine). The clustering results were consistent in all sensitivity analyses. CONCLUSIONS: The safety profile of gabapentinoids overlaps with those of some dihydropyridine CCBs and Cav -blocking anticonvulsants. These results could be used to anticipate some unidentified ADRs of gabapentinoids from information accumulated with older drugs and sharing a common molecular target and ADR signature.
