Neurological Adverse Events Associated With Esketamine: A Disproportionality Analysis for Signal Detection Leveraging the FDA Adverse Event Reporting System

Safety assessment of asenapine in the FAERS database: real adverse event analysis and discussion on neurological and psychiatric side effects

PURPOSE

This study aims to comprehensively assess the safety of Asenapine by conducting an comprehensive statistical analysis of adverse event reports in the FAERS database, with a particular focus on potential adverse reactions related to its use in the treatment of psychiatric disorders.

METHODS

Event reports from the first quarter of 2009 to the third quarter of 2023 were collected and analyzed. Detailed examinations of gender, age, reporter identity, and other aspects were conducted to reveal the fundamental characteristics of Asenapine-related adverse events. Signal mining techniques were employed to systematically evaluate various adverse reactions associated with Asenapine.

RESULTS

The study found that adverse event reports involving Asenapine were more common among female patients, with the age group mainly distributed between 18 and 45 years. Physicians were the primary reporters of adverse events, and psychiatric disorders, neurological disorders, and gastrointestinal disorders were the most common areas affected by adverse reactions. In addition to known adverse reactions, potential risks not mentioned in the drug label were identified, such as anosognosia, attentional drift, and psychogenic compensation disorder.

CONCLUSION

Asenapine carries the risk of various adverse reactions alongside its therapeutic effects. In clinical practice, physicians should closely monitor the occurrence of neurological disorders, psychiatric disorders, and gastrointestinal system disorders.

Pharmacovigilance of esketamine nasal spray: an analysis of the FDA adverse event reporting system database

Esketamine nasal spray (ESK-NS) is a new drug for treatment-resistant depression, and we aimed to detect and characterize the adverse events (AEs) of ESK-NS using the Food and Drug Administration (FDA) adverse event reporting system (FAERS) database between 2019 Q1 and 2023 Q4. Reporting odds ratio (ROR), proportional reporting ratio (PRR), and multi-item gamma Poisson shrinker (MGPS) were performed to detect risk signals from the FAERS data to identify potential ESK-NS-AEs associations. A total of 14,606 reports on AEs with ESK-NS as the primary suspected drug were analyzed. A total of 518 preferred terms signals and 25 system organ classes mainly concentrated in psychiatric disorders (33.20%), nervous system disorders (16.67%), general disorders and administration site conditions (14.21%), and others were obtained. Notably, dissociation (n = 1,093, ROR 2,257.80, PRR 899.64, EBGM 876.86) exhibited highest occurrence rates and signal intensity. Moreover, uncommon but significantly strong AEs signals, such as hand-eye coordination impaired, feeling guilty, and feelings of worthlessness, were observed. Additionally, dissociative disorder (n = 57, ROR 510.92, PRR 506.70, EBGM 386.60) and sedation (n = 688, ROR 172.68, PRR 155.53, and EBGM 142.05) both presented strong AE signals, and the former is not recorded in the Summary of Product Characteristics (SmPC). In clinical applications, close attention should be paid to the psychiatric disorders and nervous system disorders, especially dissociation. Meanwhile, clinical professionals should be alert for the occurrence of AEs signals not mentioned in the SmPC and take preventive measures to ensure the safety of clinical use.

Ocular adverse events of cenegermin used in neurotrophic keratopathy: an analysis of the FDA adverse event reporting system database

BACKGROUND

Cenegermin, a recombinant human nerve growth factor, is an orphan drug approved for neurotrophic keratitis. The safety information on the label is incomplete, and the adverse reactions noted are mostly mild and tolerable. However, the occurrence of painful epithelial plagues and irreversible corneal deposits after cenegermin usage have been reported. Real-world data on long-term ocular safety are lacking. We aimed to assess the cenegermin-associated eye safety profile in the FDA pharmacovigilance database.

METHODS

The signals of cenegermin-related ocular adverse events (AEs) from 2018 to 2022 were quantified using the reporting odds ratio (ROR) and information component (IC). The grading system was used to prioritize the signals.

RESULTS

We identified 3288 cases of cenegermin-related ocular AEs and 56 positive ocular-related signals. Fifty unexpected signals of ocular AE were identified. Eye ulcer was classified as a designated medical event. Twenty AEs, including corneal perforation, eye infection, corneal deposits, and eye inflammation, were recognized as important medical event. The median onset time for ocular AEs was 6 days (interquartile range [IQR]: 1-29 days).

CONCLUSION

This study revealed new cenegermin-related ocular AE signals. Clinical practice requires close monitoring to early identify and manage adverse reactions that may cause occurrence of serious irreversible consequences.

Real-world safety of icosapent ethyl: analysis based on spontaneous reports in FAERS database

BACKGROUND

The triglyceride-lowering drug, icosapent ethyl (IPE), was granted a new indication for the reduction of atherosclerotic cardiovascular disease risk in 2019. This study aimed to investigate the safety profile of IPE by mining the FDA Adverse Event Reporting System (FAERS) database.

METHODS

The reporting odds ratio was used to analyze IPE's adverse events (AEs) based on the FAERS data from July 2012 to December 2022. We described the characteristics of AE reports and evaluated the clinical prioritization of AEs. Then we defined and analyzed nine interested adverse drug reactions (ADRs) in both overall and subgroups, and investigated the times to onset.

RESULTS

The findings of our study strengthen the evidence for an increased risk of atrial fibrillation using IPE. IPE alone may not increase the risk of bleeding unless combined with antithrombotic drugs. Similar to statins, IPE alone can increase the risk of musculoskeletal pain, drug-related hepatic disorders, and hyperglycemia, but the risk could not double when IPE was combined with statins. Most ADRs occur in the early stage of treatment.

CONCLUSIONS

This study provides a comprehensive real-world safety profile of IPE, which indicates that IPE is well-tolerated.

The correlation of Esketamine with specific adverse events: a deep dive into the FAERS database

Analyzing the vast data from FAERS database to evaluate the association between Esketamine and specific adverse events to guide clinical practice and regulatory decisions. Data related to Esketamine adverse events from 2019 Q1 to 2023 Q1 were collected from FAERS database. After data standardization, various signal quantification technologies, such as ROR, PRR, BCPNN, and MGPS, were employed to identify and evaluate adverse reaction signals closely related to the use of Esketamine comprehensively. A total of 5061 reports with Esketamine as the primary suspected drug were obtained, identifying 117 adverse reaction terms (PT) involving 27 system organ class (SOC) categories. Apart from the adverse events already mentioned in the drug's instructions, this study identified some new, clinically valuable potential AE signals, such as Flashback, Tachyphylaxis, and Autoscopy. In addition, high-ranking results included euphoric mood, feeling of relaxation, and feeling drunk. Notably, the occurrence frequencies of suicidal ideation and suicide attempt were relatively high, so clinicians should be particularly vigilant about these potential adverse reactions when using Esketamine. Moreover, since this drug is administered as a nasal spray, issues such as drug monitoring procedure incorrectly performed and nasal discomfort may arise. This study underscores the potential adverse reactions and risks of Esketamine in clinical applications, especially regarding long-term efficacy, addiction risks, and suicidal risks.

Investigating the risk of deep vein thrombosis with JAK inhibitors: a disproportionality analysis using FDA Adverse Event Reporting System Database (FAERS)

BACKGROUND

Janus kinase (JAK) inhibitors are immune-modulating medications used to treat conditions including rheumatoid arthritis, COVID-19, ulcerative colitis, atopic dermatitis, myelofibrosis, and polycythemia Vera. However, these medications have been associated with higher incidence of deep vein thrombosis. The objective of this study was to investigate potential safety signals for DVT associated with JAK inhibitors using disproportionality analysis from the FDA Adverse Event Reporting System (FAERS) database.

RESEARCH DESIGN AND METHODS

The authors retrospectively investigated case/non-case analysis using Openvigil 2.1-MedDRA-v24 (2004Q1 to 2022Q4). The preferred term used was 'deep vein thrombosis,' and the drugs included were baricitinib, tofacitinib, and upadacitinib. Reporting odds ratio, proportional reporting ratio, and information component were used to detect signals.

RESULTS

Overall 114,005 AE reports related to JAK inhibitors were identified, of which 647 reports (baricitinib - 169, tofacitinib - 425, and upadacitinib - 53) associated with DVT were obtained from FAERS. On analysis, baricitinib and tofacitinib had greater signal strength for age group of 65-100 years and all three had the highest signal strength for male gender.

CONCLUSIONS

Our study identified signals for DVT with baricitinib, tofacitinib, and upadacitinib. Further research using well-designed epidemiological data is needed to validate these results.

Adverse events with risankizumab in the real world: postmarketing pharmacovigilance assessment of the FDA adverse event reporting system

Background

Risankizumab, a humanized IgG1 monoclonal antibody that selectively inhibits IL-23, is currently approved for the treatment of moderate-to-severe plaque psoriasis and Crohn's disease. The real-world safety study of risankizumab in a large- sample population is currently lacking. The aim of this study was to evaluate risankizumab-associated adverse events (AEs) and characterize the clinical priority through the data mining of the Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS).

Methods

Disproportionality analyses were performed by calculating the reporting odds ratios (RORs), deemed significant when the lower limit of the 95% confidence interval was greater than 1, to quantify the signals of risankizumab-related AEs from the second quarter (Q2) of 2019 to 2022 Q3. Serious and non-serious cases were compared, and signals were prioritized using a rating scale.

Results

Risankizumab was recorded in 10,235 reports, with 161 AEs associated with significant disproportionality. Of note, 37 PTs in at least 30 cases were classified as unexpected AEs, which were uncovered in the drug label, such as myocardial infarction, cataract, pancreatitis, diabetes mellitus, stress, and nephrolithiasis. 74.68%, 25.32%, and 0% PTs were graded as weak, moderate, and strong clinical priorities, respectively. A total of 48 risankizumab-related AEs such as pneumonia, cerebrovascular accident, cataract, loss of consciousness, cardiac disorder, hepatic cirrhosis, and thrombosis, were more likely to be reported as serious AEs. The median TTO of moderate and weak signals related to risankizumab was 115 (IQR 16.75-305) and 124 (IQR 29-301) days, respectively. All of the disproportionality signals had early failure type features, indicating that risankizumab-associated AEs gradually decreased over time.

Conclusion

Our study found potential new AE signals and provided valuable evidence for clinicians to mitigate the risk of risankizumab-associated AEs based on an extensive analysis of a large-scale postmarketing international safety database.

Thrifty effect of subanesthetic-dose S-ketamine on postoperative opioids and its safety and analgesic effectiveness: A prospective, triple-blind, randomized controlled, polycentric clinical trial

Aim

To investigate the thrifty effects of subanesthetic-dose S-ketamine on postoperative opioids and its safety and analgesic efficacy.

Methods

Four-hundred and twenty patients were divided into the control group (CON group), the S-ketamine 0.2 mg/kg group (ES0.2 group), and the S-ketamine 0.3 mg/kg group (ES0.3 group) randomly. Major indicators include the Visual Analogue Scale (VAS), the times of compression with analgesic pumps after surgery, and analgesic drug consumption from anesthesia induction to 48 h after surgery. Minor records include vital signs, the use of vasoactive drugs, the Ramsay scores, the occurrence of adverse events including nervous system reaction, and the patient's satisfaction with anesthesia.

Results

Compared with the CON group, VAS scores decreased in the ES0.2 and ES0.3 groups (p < 0.05). At 10 min after extubation, the VAS scores of the ES0.3 group were lower than that of the ES0.2 group (p < 0.05). The total number of compression with analgesic pumps of the ES0.3 group was lower than that of the CON group (p < 0.05). The opioid consumption after surgery of the ES0.3 group was lower than those of the CON group and the ES0.2 group (p < 0.05). The ES0.3 group's heart rate (HR) was faster but the use of vasoactive, drug consumption was less than the other two groups (p < 0.05). There were no significant differences in the incidence of postoperative adverse events and anesthetic satisfaction among the three groups.

Conclusion

Subanesthetic-dose S-ketamine at 0.2-0.3 mg/kg especially the 0.3 mg/kg in general anesthesia induction can safely and effectively reduce postoperative pain and save postoperative opioid consumption.

Postmarketing Reporting of Paxlovid-Related Dysgeusia: A Real-World Pharmacovigilance Study

OBJECTIVE

A novel COVID-19 therapeutic, nirmatrelvir/ritonavir (Paxlovid), is commonly associated with reports of dysgeusia. The Food and Drug Administration Adverse Event Reporting System (FAERS) database was used to determine the real-world reporting of Paxlovid-associated dysgeusia (PAD), identify associated factors, and describe the relative reporting rates of dysgeusia for Paxlovid compared to other COVID-19 therapeutics (OCT), ritonavir alone, and other protease inhibitors (OPI).

STUDY DESIGN

Observational retrospective.

SETTING

Tertiary academic medical center.

METHODS

We collected patient and adverse event characteristics reported in the FAERS database between January 1968 and September 2022. Disproportionality analyses were used to compare the reporting of PAD to dysgeusia reported for OCT, ritonavir, and OPI.

RESULTS

345,229 adverse events were included in the present study. Dysgeusia was a frequently reported Paxlovid-associated adverse event (17.5%) and was associated with nonserious COVID-19 infection (reporting odds ratio [ROR] 1.4; 95% confidence interval [CI] 1.2, 1.7) and female sex (ROR = 1.7; 95% CI 1.6, 1.9). Paxlovid was more likely to be associated with the reporting of dysgeusia compared to OCT (ROR 305.4; 95% CI 164.1, 568.5), ritonavir (ROR 28.0; 95% CI 24.1, 32.7), and OPI (ROR 49.0; 95% CI 42.8, 56.1).

CONCLUSION

Dysgeusia is much more likely to be reported by patients receiving Paxlovid than those receiving OCT, ritonavir alone, or OPI. These findings suggest a potential mechanism of dysgeusia that causes distorted taste out of proportion to the background effects of COVID-19 infection and specific to nirmatrelvir. Future studies are needed to determine the underlying pathophysiology and long-term clinical implications for patients who report dysgeusia with Paxlovid.

Gastrointestinal adverse events associated with semaglutide: A pharmacovigilance study based on FDA adverse event reporting system

Background

Semaglutide was approved for treatment of type 2 diabetes mellitus (T2DM) and chronic weight management in obesity or overweight adults. However, real-world data regarding its long-term gastrointestinal safety and tolerability in large sample population are incomplete. We evaluated semaglutide-associated gastrointestinal safety signals by data mining of the FDA pharmacovigilance database.

Methods

Reporting odds ratio (ROR) was employed to quantify the signals of semaglutide-related gastrointestinal adverse events (AEs) from 2018 to 2022. Serious and non-serious cases were compared by Mann-Whitney U test or Chi-squared (χ²) test, and signals were prioritized using a rating scale.

Results

We identified 5,442 cases of semaglutide-associated gastrointestinal AEs, with 45 signals detected, ranging from a ROR₀₂₅ of 1.01 (hypoaesthesia oral) to 42.03 (eructation), among which 17 AEs were identified as new and unexpected signals. Patient age (p < 0.001) and body weight (p = 0.006) rather than sex (p = 0.251) might be associated with an increased risk of gastrointestinal AEs severity. Notably, the association between semaglutide and gastrointestinal disorders remained when stratified by age, body weight, sex and reporter type. One strong, 22 moderate and 22 weak clinical priority signals were defined. The median time-to-onset (TTO) for strong clinical priority signal was 23 days, while for moderate and weak, they were 6 and 7 days, respectively. All of the disproportionality signals had early failure type features, suggesting that the risk of gastrointestinal AEs occurrence gradually decreased over time.

Conclusion

Our study provided a deeper and broader understanding of semaglutide's gastrointestinal safety profiles, which would help healthcare professionals to mitigate the risk of gastrointestinal AEs in clinical practice.

The median effective concentration of propofol in combination with different doses of esketamine during gastrointestinal endoscopy in adults

We designed a four-arm randomized controlled trial to investigate the median effective concentration (EC50) of propofol in combination with different doses of esketamine inducing appropriate depth of anaesthesia during gastrointestinal endoscopy in adults. One hundred patients aged 18-65 years planning for gastrointestinal endoscopy were divided into four groups randomly: esketamine 0, 0.15, 0.25 and 0.5 mg/kg groups (n = 25). Propofol doses followed the Dixon and Massey up-and-down method with different starting between groups. The primary endpoint was the EC50 of propofol. Secondary outcomes included the cumulative dose of propofol, the duration of the procedure, recovery time, and adverse effects. The EC50 (median, 95% confidence interval) of propofol was significantly less in the esketamine 0.5 mg/kg group compared with the esketamine 0, 0.15, and 0.25 mg/kg groups [1.34 (1.15, 1.54) vs. 3.48 (3.25, 3.71), 2.82 (2.58, 3.07), and 2.36 (2.11, 2.61), respectively; p < 0.001]. The total dose of propofol (mean ± SD) required for the whole procedure was significantly less in the esketamine 0.5 mg/kg group compared with the esketamine 0, 0.15, and 0.25 mg/kg groups [95.5 ± 43.1 vs. 277.4 ± 49.0, 207.8 ± 31.6, and 135.1 ± 27.7, respectively; p < 0.001]. The recovery time was significantly longer in esketamine 0 and 0.5 mg/kg group compared with other two groups (p < 0.001). More patients in the esketamine 0.5 mg/kg group experienced visual disturbance compared with the other groups (p = 0.016). Additionally, the incidence of hypotensionin the esketamine 0 mg/kg group after inducation was higher compared with other groups (p < 0.001). In summary, the administration of esketamine significantly and dose-dependently reduced the dose of propofol required to accomplish procedures.
