Background and objective: Performing lipid testing after statin initiation is recommended to monitor response. Inadequate response may indicate non-adherence, which is associated with an increased risk of cardiovascular events and increased costs. Group-based trajectory modeling is an approach to establish probabilistic developmental trajectories of adherence, differentiating individuals by their distinct longitudinal medication-taking behaviors. We examined whether lipid testing is associated with distinct trajectories of statin adherence among individuals enrolled in a Medicare fee-for-service plan in the USA.

Methods: A retrospective cohort study was conducted using the Centers for Medicare & Medicaid Chronic Condition Warehouse 5% sample of Medicare fee-for-service data between 2006 and 2015. Statin use and lipid testing were identified using claims data. The proportion of days covered was calculated for each 30 days after the index date, which was used to estimate the probability of belonging to each potential adherence trajectory.

Results: In a cohort of 138,101 statin initiators, four statin adherence trajectory groups were identified. The four groups were differentiated as "rapid decline" (21.53%), "gradual decline" (10.25%), "decline first then improve later" (26.47%), and "high adherence" (41.75%). Compared with "high adherence," initiators who had lipid tests within 360 days after statin initiation were less likely to fall into "rapid decline" (adjusted odds ratio: 0.661; 95% confidence interval 0.641-0.683), "gradual decline" (adjusted odds ratio: 0.834; 95% confidence interval 0.801-0.868), and "decline first then improve later" groups (adjusted odds ratio: 0.936; 95% confidence interval 0.910-0.962).

Conclusions: Lipid testing is positively associated with greater use of statin medication across different adherence trajectories in the present study.

Background: Kampo medicines are often used in Japan as therapy for the side effects induced by oral kinase inhibitors. However, the pharmacokinetic interactions between Kampo medicines and oral kinase inhibitors such as lenvatinib have not been studied.

Objective: We investigated the effects of Kampo medicines (rikkunshito, shakuyakukanzoto and goreisan) on the steady-state plasma trough concentration (C₀) of lenvatinib in patients with thyroid cancer.

Methods: Thirty-nine patients receiving lenvatinib therapy at Ito Hospital between May 2015 and December 2019 were enrolled. The mean C₀ of lenvatinib with Kampo medicine, at the same dose as before initiating Kampo medicines, was used.

Results: After the repeated administration of rikkunshito (n = 21), shakuyakukanzoto (n = 10) or goreisan (n = 8), the mean C₀ of lenvatinib and the laboratory test values of patients did not change significantly. In contrast to rikkunshito, which alleviates emesis by enhancing gastric emptying, the C₀ values of lenvatinib with a proton pump inhibitor (PPI) (n = 16) or histamine H₂ receptor antagonist (H2RA) (n = 4) were significantly lower than the C₀ values without a PPI or H2RA (P = 0.007). The mean (range) change rate of the C₀ of lenvatinib with a PPI or H2RA versus without a PPI or H2RA was 88.6% (69.9-115%), and was significantly greater than the change rate for rikkunshito (P = 0.029). There was no significant difference between the C₀ of lenvatinib with a prokinetic agent (n = 7) versus without a prokinetic agent (P = 0.365).

Conclusions: Although these Kampo medicines are reported to inhibit drug-metabolizing enzymes and drug transporters, the risk of drug interactions for patients receiving lenvatinib therapy is low. Patients should feel confident that they can receive Kampo medicines as supportive care for lenvatinib therapy without a risk of drug interactions that could affect treatment efficacy.

Background: Alirocumab is a fully human monoclonal antibody to proprotein convertase subtilisin kexin type 9 used for the reduction of low-density lipoprotein cholesterol (LDL-C) in high-risk patients not reaching their LDL-C target. Recently, a 2-mL prefilled autoinjector has been developed to support the monthly 300-mg dosing regimen with a single-injection administration.

Methods and objectives: Monthly application of 300 mg AlirRocumab (Praluent^®) using the 2-mL SYDNEY Device (MARS) is a non-interventional, open, prospective, multi-center cohort study conducted in Germany between 2021 and 2023 with an observational period of 12 weeks. Patients included had primary hypercholesterolemia (heterozygous familial or non-familial) or mixed dyslipidemia and confirmed vascular disease and other risk factors or confirmed familial heterozygous hypercholesterolemia. Primary objectives were to assess the effectiveness of the 2-mL SYDNEY autoinjector measured by the lipid-lowering effect of alirocumab and to document therapy satisfaction, patient adherence, and persistence. Secondary objectives were to assess safety (adverse events) and tolerability.

Results: A total of 146 patients were analyzed: 110 (75.3%) patients were proprotein convertase subtilisin kexin type 9 inhibitor naïve and 36 (24.7%) were pre-treated with a proprotein convertase subtilisin kexin type 9 inhibitor. Patient mean age was 65.6 years with a preponderance of male gender (59.6%). At 12 weeks, the LDL-C value had decreased by a median of 59.5 mg/dL (1.5 mmol/L) in naïve patients (median relative decrease: - 52.0%). In the pre-treated group, the LDL-C value remained mainly unchanged (median slight numerical relative increase: 1.6%). Treatment satisfaction was rated similarly in both groups with most patients being satisfied/very satisfied and rating the injection as effective, safe, and easy to handle. Twenty-three adverse events in 13 patients (8.0%) were documented. Three patients experienced one serious adverse event each; for five patients, an adverse drug reaction was observed, although none was serious. The occurrence of adverse events was similar in both groups.

Conclusions: Alirocumab 300 mg administered with the 2-mL SYDNEY autoinjector was safe and effective in lowering LDL-C after 12 weeks in a routine clinical setting in Germany. The treatment schedule was perceived to be beneficial with excellent device acceptance and satisfaction, potentially increasing patient adherence.

Background and objectives: Accumulating pediatric efficacy and safety data on drug use is inherently challenging yet essential. This study aimed to analyze the frequency and compute the odds of pediatric drug-associated liver injury across age groups (early childhood, middle childhood, and adolescence) and therapeutic categories using adverse drug reactions (ADRs) reporting data spanning nearly two decades.

Methods: We analyzed the reports of suspected ADRs occurring in children and adolescents in the Taiwan National Adverse Drug Reaction Reporting System during the period from May 1998 until July 2017. Standardized Medical Dictionary for Regulatory Activities Queries were utilized to identify suspected hepatic ADRs. Outcome patterns across age groups were compared using the chi-squared test, and disproportionality analysis was employed to calculate reporting odds ratios (RORs) of hepatic versus nonhepatic reports.

Results: Among 16,673 reports, 484 (2.9%) were identified as suspected hepatic ADRs, involving 193 distinct drugs. The mean age of affected individuals was 8.2 years. Outcome types in adolescents were predominantly serious (91.8%). Antibacterials for systemic use (18.8%) and antiepileptics (8.7%) were the most frequently implicated therapeutic categories. Drugs with high ADR occurrence rates and significant RORs included oxacillin (5.2%; ROR: 12.07), methotrexate (4.1%; ROR: 9.07), and phenobarbital (2.7%; ROR: 5.04). Some medications exhibited higher ratios of used-versus-recommended doses, suggesting inappropriate dosing.

Conclusions: Pediatric drug-associated liver injury was not uncommon and may result in serious outcomes. This study underscores the need for heightened vigilance in administering certain high-risk drugs and attentiveness in proper dosing for children, including adolescents.

Background: The combination of regorafenib and immune checkpoint inhibitor (ICI) has been the most popular second-line systemic therapy for advanced hepatocellular carcinoma (HCC). However, considering the good anti-tumor performance of lenvatinib, combined immunotherapy on the basis of lenvatinib after first-line lenvatinib failure is also popular in clinical practice. This study aimed to compare the efficacy and safety of regorafenib plus ICI (TACE-R-I) versus lenvatinib plus ICI (TACE-L-I) in patients with advanced HCC after lenvatinib failure.

Methods: In this single-center retrospective study, 164 patients with advanced HCC were enrolled from January 2019 to March 2024 in China. All patients were aged ≥ 18 years, clinically or pathologically diagnosed with HCC. All patients received trans-arterial chemoembolization (TACE) as local treatment. Overall survival (OS), progression-free survival (PFS), and treatment-related adverse events (TRAEs) were compared between groups. The Cox regression model was used to analyze the factors associated with OS and PFS.

Results: We compared 77 patients from each group after propensity score matching (PSM). There was no significant difference in the OS (p = 0.255) or PFS (p = 0.387) between groups. However, in the subgroup (distant metastases, Barcelona Clinic Liver Cancer (BCLC) stage C or tumor thrombus), the TACE-R-I group showed better survival benefit than the TACE-L-I group. The multivariable Cox regression model suggested that BCLC stage and alpha-fetoprotein (AFP) were independently associated with OS. Distant metastases, tumor thrombus and Child-Pugh were independent associated factors for PFS (p < 0.05). The frequency of grade ≥ 3 TRAEs was not significantly different between groups (p ≥ 0.05).

Conclusion: Our study demonstrated that in patients with greater tumor burden, the TACE-R-I group showed better OS and PFS benefits than the TACE-L-I group. However, in the overall population of HCC patients, there was no significant difference in efficacy and safety between the groups.

Background: Studies on medicinal cannabis (MC) have primarily investigated effects on diseases and symptoms, while there is only sparse knowledge on patients' health-related quality of life. Our aim was, firstly, to compare the health-related quality of life of patients (MC users and non-users) within four specified diagnostic indications (multiple sclerosis, paraplegia, neuropathy, and nausea and vomiting after chemotherapy) with that of patients with other diagnostic indications (MC users only) and the adult population (non-users only). Secondly, we estimate the associations between use of MC and health-related quality of life for patients in the four specified diagnostic indications.

Methods: We collected data on quality-adjusted life years (QALYs), using EQ-5D-3L, and patients' self-reported use of MC in a Danish nationwide online survey distributed to 23,846 patients in October 2020. We compared QALY scores of all groups using a two-tailed t-test, listed QALY scores of MC users versus non-users, and investigated associations between QALY score and MC use using unadjusted and adjusted linear regression analyses. Significance level was set to p-value < 0.05.

Results: A total of 9265 patients took part in the survey. All diagnostic indications had a statistically significant lower QALY score than the adult population (0.87). Paraplegia patients had the lowest QALY score, being 0.36 lower, followed by other diagnostic indication (- 0.34), multiple sclerosis (- 0.20), neuropathy (- 0.13), and nausea and vomiting after chemotherapy (- 0.06). MC users had a statistically significant lower QALY score than non-users (0.44 vs 0.74). Users redeeming 1-6 and ≥ 7 MC prescriptions (except for paraplegia patients) had a statistically significant lower QALY score than non-users, ranging between 0.11-0.24 and 0.26-0.32 lower than non-users, accordingly. Although, it should be noted that the number of users was small when stratifying by number of prescriptions.

Conclusion: Patients with either multiple sclerosis, paraplegia, neuropathy, or nausea and vomiting after chemotherapy had a significantly lower health-related quality of life than individuals from the adult population. Users of medicinal cannabis also had a significantly lower health-related quality of life compared with non-users, in all diagnostic indications.

Background: Brigatinib, a next-generation anaplastic lymphoma kinase (ALK) inhibitor was licensed for the treatment of ALK-positive metastatic non-small cell lung cancer in 2016. However, real-world evidence on the safety and effectiveness of brigatinib in Latin America remains limited.

Objective: The aim of this study was to assess the safety and effectiveness of brigatinib in the real world in Argentina.

Methods: We conducted a non-interventional cohort study of adult patients (aged ≥  18 years) with a diagnosis of ALK-positive metastatic non-small cell lung cancer not previously treated (first line) or previously treated (second line) with an ALK inhibitor and who received at least one dose of brigatinib between November 2020 and March 2023. The primary outcome was the incidence of treatment-emergent adverse events. Secondary outcomes at the 24-week follow-up were the percentage of patients with an overall best objective response rate of complete or partial response; intracranial objective response rate; progression-free survival; and overall survival.

Results: Of the 39 patients included in the study (n = 22 [first line]; n = 17 [second line]), 12 patients (30.7%) experienced treatment-emergent adverse events, with the most frequent being increased levels of transaminases (7.6%), increased level of blood creatine phosphokinase (5%) and hypokalaemia (5%). Most adverse events (85.7%) were mild to moderate. Effectiveness outcomes at 24 weeks in patients treated with brigatinib first line or second line, respectively, were as follows: overall objective response rate: 81.8% and 70.5%; intracranial objective response rate (in patients with brain metastases at baseline): 66.6% and 88.8%; progression-free survival: 93.8% and 82.4%; overall survival: 100% and 87.5%.

Conclusions: Brigatinib was demonstrated to be a safe and effective treatment option for ALK-positive metastatic non-small cell lung cancer in routine clinical practice in Argentina.

Background and objective: The terminal complement inhibitor eculizumab is approved in the USA for the treatment of patients with acetylcholine receptor antibody-positive generalized myasthenia gravis (MG). The ELEVATE study aimed to examine clinical-practice outcome data on eculizumab effectiveness in US adults with MG (generalized or ocular). This paper reports the findings on MG exacerbations and crises and associated healthcare resource utilization, and the use of rescue therapy.

Methods: A retrospective chart review was conducted of US adults with MG who initiated eculizumab. Outcomes assessed for up to 2 years before and after eculizumab initiation included percentages and rates per patient per year (PPPY) of exacerbations and crises (the latter defined as intubation/impending intubation), healthcare resource utilization, and rescue therapy administration.

Results: A total of 119 patients diagnosed with MG were enrolled in the study; 92 patients had ≥ 3 months of data both before and during eculizumab therapy and were included in the analyses. The mean rate of MG exacerbations decreased from 0.385 PPPY before eculizumab initiation to 0.152 PPPY during eculizumab treatment (p = 0.0034); the mean rate of MG crises decreased from 0.411 to 0.056 PPPY (p = 0.0018). Rates of healthcare resource utilization and rescue therapy use also decreased significantly during eculizumab treatment.

Conclusions: This retrospective chart review analysis provides evidence for a beneficial impact of eculizumab treatment on the incidence of MG exacerbations and crises and associated healthcare resource utilization in clinical practice, and on rescue therapy use. These data further support the therapeutic benefits of eculizumab in patients with MG.

Background and objective: Accurate and robust adverse event (AE) data collection is crucial in cancer clinical trials to ensure participant safety. Frameworks have been developed to facilitate the collection of AE data and now the traditional workflows are facing renewal to include patient-reported data, improving completeness of AE data. We explored one of these workflows in a cancer clinical trial unit.

Methods: The study was a single-site study conducted at a tertiary hospital located in Australia. Patients consenting to a clinical trial were eligible for inclusion in this study. Participants used an electronic platform-My Health My Way (MHMW)-to report their symptomatic data weekly for 24 weeks. A symptom list was included within the platform, along with a free text field. Data reported via the platform was compared with data recorded in the patient's medical chart. Time taken to compile data from each source was recorded, along with missing data points. Agreement between patient-reported data and data recorded in the medical notes was assessed using Kappa and Gwet's AC₁; time taken to compile data and missing data points were assessed using a Wilcoxon signed rank test.

Results: Low agreement was found between patient- and clinician-reported data (- 0.482 and - 0.159 by Kappa and Gwet's AC₁ respectively). Only 127 (30%) of the total 428 AEs were reported by both MHMW and medical notes. Patients reported higher rates of symptoms from the symptom list, while clinicians reported higher rates of symptoms outside of the symptom list. Time taken to compile the data from MHMW was significantly less than that taken to review medical notes (2.19 min versus 5.73 min respectively; P <  0.001). There were significantly less missing data points from the MHMW data compared with the medical notes (1.4 versus 7.8; P < 0.001).

Conclusions: This study confirms previous reports that patient- and clinician-reported adverse event data show low agreement. This study also shows that clinical trial sites could significantly reduce the work performed by research staff in the collection of adverse event data by implementing an electronic, patient-reported platform.

Introduction: The association between omeprazole and hypertension is poorly documented. The summary of product characteristics of omeprazole approved by major regulators did not mention hypertension as an adverse drug event. Triggered by a locally reported case, this study was conducted to assess the possible causal relationship between omeprazole and hypertension.

Methods: Globally reported cases of hypertension following use of omeprazole submitted to the World Health Organization global database, VigiBase, were retrieved on 5 March 2024 and analyzed descriptively. Besides this, a literature search was made to identify preclinical, clinical, and epidemiological information on the association between omeprazole and hypertension or increased blood pressure using different data sources. Relevant information, gathered from different data sources, was finally systematically organized into an Austin Bradford-Hill causality assessment framework to assess the causal relationship between omeprazole and hypertension.

Results: VigiBase indicated a total of 1043 cases of hypertension related to omeprazole from 36 different countries. In the global database, a statistical signal was triggered (IC₀₂₅: 0.12) on association of omeprazole and hypertension. From the 1043 cases, 65.0% and 10.6% were reported as 'serious' and 'fatal', respectively. Hypertension resolved following withdrawal of omeprazole in 85 cases and recurred after re-introduction of the suspect drug in 14 cases. In 225 cases, omeprazole was the only suspected drug, while in 122 cases, omeprazole was the sole drug administered. When only these 122 cases were considered, 29 cases had positive dechallenge, four cases were with positive rechallenge and the median time-to-onset was 2 days. Literature search identified a possible biological mechanism and some experimental evidence that indicates omeprazole could possibly cause hypertension.

Conclusion: Currently available totality of evidence suggests there is a possible causal relationship between omeprazole and hypertension. Hence, it is recommended to monitor and report any incidence of hypertension related to omeprazole, and further epidemiological studies are recommended to corroborate the suggested causal association.
