ABSTRACT

The concept of pharmacovigilance (PV) is currently highlighted after emergency authorization and worldwide distribution of the urgently launched COVID-19 novel vaccinations. As they typically serve as the initial point of patient contact for medication-related issues, understanding the knowledge, perspectives, and attitudes of community pharmacists in PV and reporting adverse drug reactions (ADRs) is crucial to improving the healthcare system and public health policies. However, previous studies in Jordan have not focused entirely on community pharmacists. This study aimed to assess community pharmacists' knowledge, perspectives, and attitudes on PV and ADRs reporting in Jordan. The applied methodology in this study was based on a cross-sectional study design using a validated questionnaire distributed to a convenient sample of Jordanian community pharmacists. Seventeen questions were designed from different pieces of literature relating to knowledge, perspectives, and attitudes of PV among community pharmacists. Descriptive statistics (frequencies and percentages) were used to report the results data. The study questionnaire was completed by 180 of 325 community pharmacists willing to participate (a response rate of 55.4%). Of them (n = 132, 73%) were aware of the concept of PV. Additionally (n = 84, 47%) of the community pharmacists would use the concept and policy of PV in their everyday work. Nevertheless, only (n = 36, 20.0%) of the community pharmacists thought an ADR should be reported if seen, and approximately 120 pharmacists (67.0%) believed it was essential to report ADRs as patient health matters. Although community pharmacists in Jordan showed a considerable awareness level of PV, they demonstrated a low level of its application. Thus, ADR reporting is not considered a mainstay among them, and the implementation of PV is not yet addressed. The results from this study shed light on community pharmacists' perceptions and attitudes regarding ADR reporting and PV.

ABSTRACT

Nonclinical studies involve in vitro, in silico, and in vivo experiments to assess the toxicokinetics, toxicology, and safety pharmacology of drugs according to regulatory requirements by a national or international authority. In this review, we summarize the potential effects of various underlying diseases governing the absorption, distribution, metabolism, and excretion (ADME) of drugs to consider the use of animal models of diseases in nonclinical trials. Obesity models showed alterations in hepatic metabolizing enzymes, transporters, and renal pathophysiology, which increase the risk of drug-induced toxicity. Diabetes models displayed changes in hepatic metabolizing enzymes, transporters, and glomerular filtration rates (GFR), leading to variability in drug responses and susceptibility to toxicity. Animal models of advanced age exhibited impairment of drug metabolism and kidney function, thereby reducing the drug-metabolizing capacity and clearance. Along with changes in hepatic metabolic enzymes, animal models of metabolic syndrome-related hypertension showed renal dysfunction, resulting in a reduced GFR and urinary excretion of drugs. Taken together, underlying diseases can induce dysfunction of organs involved in the ADME of drugs, ultimately affecting toxicity. Therefore, the use of animal models of representative underlying diseases in nonclinical toxicity studies can be considered to improve the predictability of drug side effects before clinical trials.

ABSTRACT

BACKGROUND OBJECTIVES: Expenditure on healthcare is a major concern in the geriatric age group. The current study was carried out to assess the expenditure patterns on medicines utilized in geriatric inpatients.

METHODS: An observational study was conducted on 1000 geriatric inpatients, aged ≥60 yr, admitted to the medicine unit. Data were collected regarding demographic characteristics, prescribed medicines, expenditure incurred on medicines, appropriateness of medicines prescribed and adverse drug reactions (ADRs). Appropriateness of the prescribed medicines was determined using the American Geriatrics Society 2015 Updated Beers Criteria.

RESULTS: Geriatric inpatients comprised 41.3 per cent of the total individuals admitted in the ward during the study period. A total of 8366 medicines were prescribed in 127 formulations. The total expenditure on prescribed medicines was INR 1,087,175 with a per capita expenditure of INR 1087.17. Parenteral medicines accounted for 91 per cent of the expenditure on medicines. Maximum expenditure (70%) was incurred on 11.9 per cent of the medicines prescribed. The per capita expenditure was significantly higher in individuals with comorbidities (P=0.03) and those who had a longer duration of hospital stay (P<0.0001). About 28.1 per cent prescriptions were inappropriate. ADRs (140) were observed in 139 (13.9%) inpatients. Individuals with inappropriate medicines prescriptions and ADRs had a longer duration of hospital stay and more number of medicines prescribed.

INTERPRETATION CONCLUSIONS: Comorbidities, prolonged hospitalization, polypharmacy, inappropriate medicines and parenteral medicines being prescribed contribute to increased expenditure on medicines in geriatric inpatients. In view of the rising number of geriatric inpatients, there is a need to frame a drug policy for them along with surveillance of expenditure on prescribed medicines. This needs to be treated as a priority.

ABSTRACT

OBJECTIVES: Haemodynamic changes following intravenous acetaminophen are well studied in adults. Limited data are published in critically ill paediatric patients, especially from the Middle East. We aim to investigate haemodynamic effects and incidence of hypotension with intravenous acetaminophen in critically ill children, with a focus on understanding factors influencing these effects.

METHODS: We retrospectively reviewed patients who received intravenous acetaminophen between July and December 2022. A haemodynamic event was defined as drop of >15% in systolic blood pressure (SBP) or mean arterial blood pressure (MAP) within 120 min after drug administration. Hypotension was defined as either drop in SBP below the 5th percentile for age, or a haemodynamic event associated with tachycardia, increased lactate or treatment with fluid/vasopressors. Logistic regression was performed to quantify relationships between patients' characteristics and the occurrence of haemodynamic event and hypotension.

RESULTS: A haemodynamic event was observed in 50/156 patients (32%) post-acetaminophen. Mean MAP (SD) before and after acetaminophen was 69.6 mm Hg (14.8) and 67.4 mm Hg (13.9), respectively (p=0.001). Mean SBP (SD) before and after acetaminophen was 95.4 mm Hg (18.2) and 92.8 mm Hg (19.2), respectively (p=0.006). Baseline MAP, median (interquartile range (IQR)) was 76.0 (64.0-85.3) and 66.0 (57.0-74.5) in patients with and without haemodynamic events, respectively (p=0.004). Only 38/156 patients (24%) met the definition for hypotension. Baseline MAP, median (IQR) was 62.0 (51.8-79.0) in patients with, and 68.5 (62.0, 79.3) in patients without hypotension (p=0.036). Baseline shock, vasoactives, mechanical ventilation and paediatric sequential organ failure assessment were not significantly associated with hypotension. Only MAP was found to be associated with both haemodynamic event (adjusted odds ratio (AOR) 1.05, 95% CI 1.02-1.10) and hypotension (AOR 1.06, 95% CI 1.02-1.10) even after controlling for other confounders.

CONCLUSIONS: Administration of intravenous acetaminophen in critically ill children can lead to haemodynamic changes, including clinically significant hypotensive events.

ABSTRACT

Anabolic treatment is indicated for high and very-high risk patients with osteoporosis, but acceptance is limited because current anabolic medications require subcutaneous injections. The purpose of this study was to assess the effects of a novel orally administered parathyroid hormone (PTH) tablet on serum markers of bone formation [N-terminal propeptide of Type I procollagen (PINP) and osteocalcin (OC)] and bone resorption [crosslinked C-telopeptide (CTX)], bone mineral density (BMD) and safety in postmenopausal women with low BMD or osteoporosis. In this 6-month, double-blind, placebo-controlled study, 161 patients were randomized to oral PTH tablets containing 0.5, 1.0, 1.5, or 2.5 mg or placebo daily. Biochemical markers were assessed at 1, 2, 3 and 6 months and BMD of lumbar spine, total hip and femoral neck was measured at 6 months. Biochemical marker changes were dose dependent with minimal or no effect at the two lowest doses. At the highest dose (2.5 mg once daily), serum PINP and OC levels increased 30% within 1 month after oral PTH initiation (p < 0.0001), remained elevated through 3 months and were back to baseline at 6 months. In contrast, serum CTX levels declined 16% and 21% below baseline at 3 and 6 months respectively (both p ≤ 0.02). At 6 months, 2.5 mg tablets increased mean BMD vs placebo of the lumbar spine by 2.7%, total hip by 1.8%, and femoral neck by 2.8% (all p ≤ 0.01). There were no drug-related serious adverse events. The most common adverse events were headache, nausea, and dizziness. In contrast to subcutaneous PTH, the oral PTH tablet appears to increase BMD rapidly by the dual mechanism of stimulating formation and inhibiting bone resorption. This might be the first effective oral anabolic alternative to subcutaneous administration for the treatment of low BMD or osteoporosis.

ABSTRACT

Drug-induced hepatotoxicity constitutes a major reason for non-approval and post-marketing withdrawal of pharmaceuticals. In many cases, preclinical models lack predictive capacity for hepatic damage in humans. A vital concern is the integration of immune system effects in preclinical safety assessment. The immune-related Adverse Outcome Pathway (irAOP) approach, which is applied within the Immune Safety Avatar (imSAVAR) consortium, presents a novel method to understand and predict immune-mediated adverse events elicited by pharmaceuticals and thus targets this issue. It aims to dissect the molecular mechanisms involved and identify key players in drug-induced side effects. As irAOPs are still in their infancy, there is a need for a model irAOP to validate the suitability of this tool. For this purpose, we developed a hepatotoxicity-based model irAOP for recombinant human IL-2 (aldesleukin). Besides producing durable therapeutic responses against renal cell carcinoma and metastatic melanoma, the boosted immune activation upon IL-2 treatment elicits liver damage. The availability of extensive data regarding IL-2 allows both the generation of a comprehensive putative irAOP and to validate the predictability of the irAOP with clinical data. Moreover, IL-2, as one of the first cancer immunotherapeutics on the market, is a blueprint for various biological and novel treatment regimens that are under investigation today. This review provides a guideline for further irAOP-directed research in immune-mediated hepatotoxicity.

ABSTRACT

BACKGROUND: Anastrozole is a selective aromatase inhibitor used for the treatment of postmenopausal hormone-sensitive breast cancer. The major side effects include osteoporosis, hypercholesterolemia, and musculoskeletal events, such as arthralgia and myalgia. Other adverse events are rare, including symptoms of acne, masculinization, and drug-induced liver injury, with the latter reported in a few cases only.

CASE: Here, we report on a patient under anastrozole therapy who developed drug-induced liver injury as assessed by the updated Roussel Uclaf Causality Assessment Method 5 weeks after a mild SARS-CoV-2 infection, which is, to the best of our knowledge, the first report of its kind involving anastrozole. Discontinuation of anastrozole resulted in a marked improvement of the alanine aminotransaminase, and aspartate aminotransaminase as well as normalized lactate dehydrogenase serum levels already seen after 26 days. Surprisingly, however, the cholestatic serum markers gamma-glutamyl transpeptidase and alkaline phosphatase showed a further rise, and took another 4 weeks to drop significantly.

CONCLUSION: The presentation of this case is meant to alert physicians to a potential drug-induced liver injury following mild SARS-CoV-2 infection in patients under anastrozole medication.

ABSTRACT

INTRODUCTION: Acute pancreatitis (AP) following drug-induced hypertriglyceridemia is a rare clinical phenomenon. Immune checkpoint inhibitors have revolutionized treatment for a variety of solid organ and hematological malignancies. Pembrolizumab is a programmed cell death receptor-1 (PD-1) inhibitor that has shown promising responses in many advanced cancers. However, a constellation of immune-related adverse events has also been described. There are reports of pembrolizumab-induced hypertriglyceridemia, but AP as a result of this side effect remains an exceedingly rare clinical sequela.

CASE REPORT: We delineate a case of a patient with stage IVB non-small-cell lung cancer who developed progressive abdominal pain and nausea following administration of pembrolizumab for four months. Laboratory studies revealed increased serum lipase and triglyceride levels at 12,562 IU/L and 16,901 mg/dL, respectively. The diagnosis of AP was made based on the revised Atlanta classification criteria. After ruling out alternative causes, pembrolizumab-induced hypertriglyceridemia was considered the likely etiology of AP.

MANAGEMENT AND OUTCOME: The patient was transferred to the medical intensive care unit for close monitoring. Treatment was initiated with intravenous fluids, pain medications, and an insulin infusion. However, her hypertriglyceridemia levels remained persistently elevated, necessitating therapeutic apheresis. She recovered well with no complications after triglyceride apheresis.

DISCUSSION: AP following pembrolizumab-associated hypertriglyceridemia remains a rare clinicopathologic entity. Given the widespread clinical use of immune checkpoint inhibitors, knowledge of such rare adverse events is crucial. Evaluation of serum triglyceride levels before and after initiating pembrolizumab therapy may be mandated, especially in patients with metabolic comorbidities.

ABSTRACT

BACKGROUND AND PURPOSE: Primary mitochondrial diseases (PMDs) are common inborn errors of energy metabolism, with an estimated prevalence of one in 4300. These disorders typically affect tissues with high energy requirements, including heart, muscle and brain. Epilepsy may be the presenting feature of PMD, can be difficult to treat and often represents a poor prognostic feature. The aim of this study was to develop guidelines and consensus recommendations on safe medication use and seizure management in mitochondrial epilepsy.

METHODS: A panel of 24 experts in mitochondrial medicine, pharmacology and epilepsy management of adults and/or children and two patient representatives from seven countries was established. Experts were members of five different European Reference Networks, known as the Mito InterERN Working Group. A Delphi technique was used to allow the panellists to consider draft recommendations on safe medication use and seizure management in mitochondrial epilepsy, using two rounds with predetermined levels of agreement.

RESULTS: A high level of consensus was reached regarding the safety of 14 out of all 25 drugs reviewed, resulting in endorsement of National Institute for Health and Care Excellence guidelines for seizure management, with some modifications. Exceptions including valproic acid in POLG disease, vigabatrin in patients with γ-aminobutyric acid transaminase deficiency and topiramate in patients at risk for renal tubular acidosis were highlighted.

CONCLUSIONS: These consensus recommendations describe our intent to improve seizure control and reduce the risk of drug-related adverse events in individuals living with PMD-related epilepsy.

ABSTRACT

OBJECTIVE: Evaluate efficacy, safety, and tolerability of adjunctive brivaracetam (BRV) in adult Asian patients with focal-onset seizures (FOS).

METHODS: Phase III, randomized, double-blind, placebo-controlled study (EP0083; NCT03083665) evaluating BRV 50 mg/day and 200 mg/day in patients (≥16-80 years) with FOS with/without secondary generalization (focal to bilateral tonic-clonic seizures) despite current treatment with 1 or 2 concomitant antiseizure medications. Following an 8-week baseline, patients were randomized 1:1:1 to placebo, BRV 50 mg/day, or BRV 200 mg/day, and entered a 12-week treatment period. Efficacy outcomes: percent reduction over placebo in 28-day FOS frequency (primary); 50% responder rate in FOS frequency; median percent reduction in FOS frequency from baseline; seizure freedom during treatment period (secondary). Primary safety endpoints: incidences of treatment-emergent adverse events (TEAEs); TEAEs leading to discontinuation; serious TEAEs.

RESULTS: In this study, 448/449 randomized patients (mean age, 34.5 years; 53.8% female) received ≥1 dose of study medication (placebo/BRV 50 mg/BRV 200 mg/day: n = 149/151/148). Percent reduction over placebo in 28-day adjusted FOS frequency was 24.5% (p = 0.0005) and 33.4% (p < 0.0001) with BRV 50 mg/day and 200 mg/day, respectively, 50% responder rate was 19.0%, 41.1%, and 49.3% with placebo, BRV 50 mg/day, and BRV 200 mg/day, respectively (p < 0.0001 for both BRV groups vs. placebo). Median percent reduction in FOS frequency from baseline was 21.3%/38.9%/46.7% in patients on placebo/BRV 50 mg/BRV 200 mg/day, respectively. Overall, 0, 7 (4.6%), and 10 (6.8%) patients were classified as seizure-free during the treatment period on placebo, BRV 50 mg/day, and BRV 200 mg/day, respectively (p = 0.0146/p = 0.0017 for BRV 50 mg/200 mg/day vs. placebo, respectively). TEAE incidences were similar between patients on placebo (58.4%) and all patients receiving BRV (58.5%); TEAE incidences for BRV 50 mg/day and BRV 200 mg/day were 57.0% and 60.1%, respectively. Overall, 0.7% of patients on placebo and 2.0% of all patients on BRV reported serious TEAEs (incidences for BRV 50 mg/day and BRV 200 mg/day were 1.3% and 2.7%, respectively), 20.1% of patients on placebo and 33.1% of all patients on BRV reported drug-related TEAEs (incidences for BRV 50 mg/day and BRV 200 mg/day were 26.5% and 39.9%, respectively), and 4.7% of patients on placebo and 3.0% of all patients on BRV discontinued due to TEAEs (discontinuation incidences for BRV 50 mg/day and BRV 200 mg/day were 2.6% and 3.4%, respectively).

SIGNIFICANCE: Adjunctive BRV was efficacious and well tolerated in adult Asian patients with FOS. Efficacy and safety profiles were consistent with BRV studies in predominantly non-Asian populations.

PLAIN LANGUAGE SUMMARY: Brivaracetam is used to treat partial or focal seizures in people with epilepsy. Most studies with brivaracetam tablets have involved people from non-Asian racial backgrounds. In this study, 449 Asian adults with epilepsy took part. One third took 50 mg of brivaracetam, one third took 200 mg of brivaracetam, and one third took a placebo each day for 12 weeks. On average, those who took brivaracetam had fewer seizures than those given the placebo. Most of the side effects were mild and the number and type of side effects seen were as expected for this medication.

ABSTRACT

Chiang Mai encounters severe pollution during the wildfire season. Wildland firefighters encounter various hazards while engaged in fire suppression operations, which encompass significant exposure to elevated concentrations of air pollutants resulting from combustion, especially particulate matter. The adverse effects of wildfire smoke on respiratory health are a significant concern. The objective of this study was to examine the potential adverse effects of PM2.5 exposure on the respiratory function and DNA damage of wildland firefighters. This prospective cohort study conducted in Chiang Mai from January to May 2022 planned to evaluate the health status of wildland firefighters during the pre-peak, peak, and post-peak ambient air pollution seasons. The measurement of PM2.5 was done at every forest fire station, as well as utilizing data from the Pollution Control Department. Participants received general health examinations, spirometry evaluations, and blood tests for DNA damage analysis. Pair t-tests and multiple regression models were used to examine the connection between pulmonary function parameters (FVC, FEV1) and PM2.5 concentration, with a significance level of P < 0.05. Thirty-three peak-season and twenty-one post-peak-season participants were enrolled. Four pre-peak-season wildland firefighters had FVC and FEV1 declines of > 15%. Multiple regression analysis showed a negative association between PM2.5 exposure and FVC% predicted (- 2.81%, 95% CI - 5.27 to - 0.34%, P = 0.027) and a marginally significant negative correlation with FVC (- 114.38 ml, 95% CI - 230.36 to 1.59 ml, P = 0.053). The remaining pulmonary measures showed a statistically insignificant decline. There were no significant changes in DNA damage detected. Wildland firefighters suffered a significant decline in pulmonary function associated with PM2.5 exposure. Spirometry is crucial for monitoring and promptly identifying respiratory issues that occur during wildfire seasons. Further research is recommended to explore DNA damage alterations and their potential association with PM2.5.

ABSTRACT

BACKGROUND: Approximately 262 million people worldwide are affected by asthma, and the overuse of reliever medication-specifically, short-acting beta2-agonist (SABA) overuse-is common. This can lead to adverse health effects. A smartphone app, the Asthma app, was developed via a participatory design to help patients gain more insight into their SABA use through monitoring and psychoeducation.

OBJECTIVE: This pilot study aims to evaluate the feasibility and usability of the app. The preliminary effects of using the app after 3 months on decreasing asthma symptoms and improving quality of life were examined.

METHODS: A mixed methods study design was used. Quantitative data were collected using the app. Asthma symptoms (measured using the Control of Allergic Rhinitis and Asthma Test) and the triggers of these symptoms were collected weekly. Quality of life (36-Item Short-Form Health Survey) was assessed at baseline and after 3, 6, and 12 months. User experience (System Usability Scale) was measured at all time points, except for baseline. Furthermore, objective user data were collected, and qualitative interviews, focusing on feasibility and usability, were organized. The interview protocol was based on the Unified Theory of Acceptance and Use of Technology framework. Qualitative data were analyzed using the Framework Method.

RESULTS: The baseline questionnaire was completed by 373 participants. The majority were female (309/373, 82.8%), with a mean age of 46 (SD 15) years, and used, on average, 10 SABA inhalations per week. App usability was rated as good: 82.3 (SD 13.2; N=44) at 3 months. The Control of Allergic Rhinitis and Asthma Test score significantly improved at 3 months (18.5) compared with baseline (14.8; β=.189; SE 0.048; P<.001); however, the obtained score still indicated uncontrolled asthma. At 3 months, there was no significant difference in the quality of life. Owing to the high dropout rate, insufficient data were collected at 6 and 12 months and were, therefore, not further examined. User data showed that 335 users opened the app (250/335, 74.6%, were returning visitors), with an average session time of 1 minute, and SABA registration was most often used (7506/13,081, 57.38%). Qualitative data (from a total of 4 participants; n=2, 50% female) showed that the participants found the app acceptable and clear. Three participants stated that gaining insight into asthma and its triggers was helpful. Two participants no longer used the app because they perceived their asthma as controlled and, therefore, did not use SABA often or only used it regularly based on the advice of the pulmonologist.

CONCLUSIONS: The initial findings regarding the app's feasibility and usability are encouraging. However, the notable dropout rate underscores the need for a cautious interpretation of the results. Subsequent studies, particularly those focusing on implementation, should explore the potential integration of the app into standard treatment practices.

ABSTRACT

Drug-related muscular adverse effects are relatively common among certain groups of drugs, such as statins and steroids. However, these adverse effects are less well-known for angiotensin receptor blockers (ARBs). It is proposed that telmisartan and irbesartan may cause myotoxicity via increased Peroxisome Proliferator-Activated Receptor gamma (PPAR-gamma) activity. Herein, we present two hypertensive patients in whom telmisartan-induced myotoxicity was observed. Therefore, physicians should be aware that telmisartan, along with some other ARBs, can also cause myopathy. Possible drug-drug interactions should be considered in cases of concomitant prescription of these agents with other myopathic drugs.

ABSTRACT

OBJECTIVE: Cenobamate is an antiseizure medication (ASM) associated with high rates of seizure freedom and acceptable tolerability in patients with focal seizures. To achieve the optimal cenobamate dose for maximal potential effectiveness while avoiding or minimizing drug-related adverse events (AEs), the administration of cenobamate with other ASMs must be managed through concomitant ASM load reduction. A panel of Spanish epilepsy experts aimed to provide a Spanish consensus on how to adjust the dose of concomitant ASMs in patients with drug-resistant epilepsy (DRE) in order to improve the effectiveness and tolerability of adjunctive cenobamate.

METHODS: A three-stage modified Delphi consensus process was undertaken, including six Spanish epileptologists with extensive experience using cenobamate. Based on current literature and their own expert opinion, the expert panel reached a consensus on when and how to adjust the dosage of concomitant ASMs during cenobamate titration.

RESULTS: The expert panel agreed that tailored titration and close follow-up are required to achieve the best efficacy and tolerability when initiating cenobamate in patients receiving concomitant ASMs. When concomitant clobazam, phenytoin, phenobarbital, and sodium channel blockers are taken at high dosages, or when the patient is receiving two or more sodium channel blockers, dosages should be proactively lowered during the cenobamate titration period. Other concomitant ASMs should be reduced only if the patient reports a moderate/severe AE at any stage of the titration period.

SIGNIFICANCE: Cenobamate is an effective ASM with a dose-dependent effect. To maximize effectiveness while maintaining the best tolerability profile, co-medication management is needed. The recommendations included herein provide practical guidance for proactive and reactive management of co-medication in cenobamate-treated patients with DRE and a high drug load.

PLAIN LANGUAGE SUMMARY: Patients with epilepsy may continue to have seizures even after treatment with several different antiseizure medications (ASMs). Cenobamate is an ASM that can reduce seizures in these patients. In this study, six Spanish experts in epilepsy discussed the best way to use cenobamate in drug-resistant epilepsy. They provide practical guidance on when and how the dose of other ASMs might be adjusted to reduce side effects and optimize the use of cenobamate.

ABSTRACT

BACKGROUND AND AIM: This study aimed to clarify the efficacy and safety of 48-week pemafibrate treatment in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) complicated by dyslipidemia.

METHODS: A total of 110 patients diagnosed with MASLD complicated by dyslipidemia received pemafibrate at a dose of 0.1 mg twice daily for 48 weeks.

RESULTS: The participants were 54 males and 37 females, with a median age of 63 (52-71) years. Besides improvement in lipid profile, significant reductions from baseline to 48 weeks of treatment were found in liver-related enzymes, such as aspartate aminotransferase, alanine aminotransferase (ALT), gamma-glutamyl transpeptidase, and alkaline phosphatase (P < 0.001 for all). A significant decrease in the homeostasis model assessment-insulin resistance (HOMA-IR) was observed in patients with insulin resistance (HOMA-IR ≥ 2.5) (4.34 at baseline to 3.89 at Week 48, P < 0.05). Moreover, changes in ALT were weakly correlated with those in HOMA-IR (r = 0.34; p < 0.05). Regarding noninvasive liver fibrosis tests, platelets, Wisteria floribunda agglutinin-positive Mac-2-binding protein, type IV collagen 7s, and the non-alcoholic fatty liver disease fibrosis score significantly decreased from baseline to Week 48. Most adverse events were Grades 1-2, and no drug-related Grade 3 or higher adverse events were observed.

CONCLUSION: This study demonstrated that 48-week pemafibrate administration improved liver-related enzymes and surrogate marker of liver fibrosis in patients with MASLD. The improvement of insulin resistance by pemafibrate may contribute to the favorable effect on MASLD complicated by dyslipidemia.

ABSTRACT

Combination therapies in metastatic hormone-sensitive prostate cancer (mHSPC), which include the addition of an androgen receptor signaling inhibitor and/or docetaxel to androgen deprivation therapy, have been a game changer in the management of this disease stage. However, these therapies come with their fair share of toxicities and side effects. The goal of this observational study is to report drug-related adverse events (AEs), which are correlated with systemic combination therapies for mHSPC. Determining the optimal treatment option requires large cohorts to estimate the tolerability and AEs of these combination therapies in "real-life" patients with mHSPC, as provided in this study. We use a network of databases that includes population-based registries, electronic health records, and insurance claims, containing the overall target population and subgroups of patients defined by unique certain characteristics, demographics, and comorbidities, to compute the incidence of common AEs associated with systemic therapies in the setting of mHSPC. These data sources are standardised using the Observational Medical Outcomes Partnership Common Data Model. We perform the descriptive statistics as well as calculate the AE incidence rate separately for each treatment group, stratified by age groups and index year. The time until the first event is estimated using the Kaplan-Meier method within each age group. In the case of episodic events, the anticipated mean cumulative counts of events are calculated. Our study will allow clinicians to tailor optimal therapies for mHSPC patients, and they will serve as a basis for comparative method studies.

ABSTRACT

BACKGROUND: Adalimumab biosimilar MSB11022 (Idacio ®) has been approved for the same indications as its originator (Humira ®), based on findings from clinical trials in plaque psoriasis. Data on its efficacy and safety in inflammatory bowel disease, however, are scarce.

METHODS: Retrospective, observational study of 44 patients with inflammatory bowel disease: 30 were treated with originator adalimumab, 5 were directly started on MSB11022, and 9 switched from originator to biosimilar adalimumab. To evaluate the effectiveness of the use of adalimumab in inflammatory bowel disease, both laboratory markers (fecal calprotectin and C-reactive protein) and scales that measure the activity of inflammatory bowel disease using specific scales (Harvey-Bradshaw Index (HBI) have been usEd.) for Crohn's disease and Mayo Score for Ulcerative Colitis. Efficacy was evaluated by recording the adverse effects that could occur with the administration of adalimumab (original or biosimilar). The success of the switch was determined by analyzing meaningful differences in effectiveness and safety criteria. Concomitant therapy and the need for dose intensification were also analyzed. Objective of this study was to assess the effectiveness and safety of biosimilar adalimumab in adalimumab-naïve patients and patients switched from originator adalimumab.

RESULTS: No significant differences were observed in clinical disease activity (P=.317) or biochemical parameters [fecal calprotectin (P=.445) and C-reactive protein P=.661)] after the switch from the originator adalimumab to MSB11022. There was not a significant reduction in the concomitant use of corticosteroids and thiopurines (P=.157). No emergency room visits or hospitalizations were observed during the study period and none of the patients experienced serious adverse effects.

CONCLUSIONS: Between originator adalimumab and biosimilar-start cohorts, no differences were observed, between originator adalimumab and switch cohorts, no significant differences were found either, and with the pre- and post-switch to biosimilar comparison, 2 of the 9 patients experienced AEs after the switch. The biosimilar showed a favorable safety profile (one patient with a serious adverse effect (rash) with biosimilar discontinued treatment) and no significant changes to clinical or biochemical parameters were observed after the switch.
