RESUMEN
INTRODUCTION: Pharmacogenetics evaluates how genetic variations influence drug responses. Nowadays, genetic tests have advanced, becoming more affordable, and its integration is supported by stronger clinical evidence. Guidelines such as those from CPIC (Clinical Pharmacogenetics Implementation Consortium) and resources like PharmGKB facilitate genotype-based prescribing; and organizations like the FDA promote genetic testing before initiating certain medications. Preventive pharmacogenetic panels seem promising, but further research on biomarkers and diverse populations is needed. The aim of this review is to analyze recent evidence on the genotype-drug response relationship to examine how the genetic profile of patients influences the clinical response to treatments, and analyze the areas of research that need further study to advance towards a genetic-based precision medicine. MATERIALS AND METHODS: A systematic search was conducted on PubMed to identify articles investigating the genotype-drug response relationship. The search strategy included terms such as "pharmacogenetics", "personalized treatment", "precision medicine", "dose adjustment", "individualized dosing", "clinical routine" and "clinical practice." Clinical trials, observational studies, and meta-analyses published in English or Spanish between 2013 and 2023 were included. The initial search resulted in a total of 136 articles for analysis. RESULTS: 49 articles were included for the final analysis following review by two investigators. A relationship between genetic polymorphisms and drug response or toxicity was found for drugs such as opioids, GLP-1 agonists, tacrolimus, oral anticoagulants, antineoplastics, atypical antipsychotics, efavirenz, clopidogrel, lamotrigine, anti-TNF-α agents, voriconazole, antidepressants, or statins. However, for drugs like metformin, quetiapine, irinotecan, bisoprolol, and anti-VEGF agents, no statistically significant association between genotype and response was found. CONCLUSION: The studies analyzed in this review suggest a strong correlation between genetic variability and individual drug responses, supporting the use of pharmacogenetics for treatment optimization. However, for certain drugs like metformin or quetiapine, the influence of genotype on their response remains unclear. More studies with larger sample sizes, greater ethnic diversity, and consideration of non-genetic factors are needed. The lack of standardization in analysis methods and accessibility to genetic testing are significant challenges in this field. As a conclusion, pharmacogenetics shows immense potential in personalized medicine, but further research is required.

RESUMEN
BACKGROUND: Negative outcomes associated with medications (NOM) and drug-related problems (DRP) significantly impact individuals with kidney replacement therapy (KRT) given the complexities of managing kidney disease and associated comorbidities. The present study aims to assess the frequency of NOMs/DRPs among KRT patients and identify contributing factors. METHODS: A cross-sectional study was conducted at Virgen de las Nieves University Hospital (Granada, Spain), involving 117 outpatient adults with KRT. Data were collected from February 2021 to July 2023 using electronic records, semi-structured interviews (Dáder Method), and discussions with nephrology specialists. NOMs/DRPs were identified following treatment guidelines. Binary logistic regression was used to determine associated factors (p-value < 0.05). RESULTS: Across 117 patients, 2436 NOMs and 3303 DRPs were identified, averaging 20.82 NOMs and 28.23 DRPs per patient. Prevalent NOMs included untreated conditions (58.95%), quantitative ineffectiveness (35.43%), and non-quantitative safety problems (5.13%). Dominant DRPs were undertreated conditions (37.63%), wrong dose/posology/length (33.00%), risk of adverse drug reactions (ADR) (16.14%), and non-adherence (6.87%). Patients with ADR, undertreated conditions, and anemia were associated with quantitative ineffectiveness. Risk of ADR and vitamin D deficiency/insufficiency correlated with non-quantitative safety problems. CONCLUSIONS: KRT patients exhibited a substantial prevalence of NOMs/DRPs. Further research is needed to deepen our understanding of these complexities for improved patient care.
RESUMEN
OBJECTIVE: To develop a checklist to facilitate pharmaceutical care for patients with interstitial lung disease who require or are undergoing treatment with antifibrotic drugs. METHOD: Five hospital pharmacists developed an initial list of 37 items divided into 4 blocks: (1) First visit, which included general patient data and data from the first treatment; (2) follow-up visits, assessing aspects of the follow-up of the treatment with nintedanib or pirfenidone; (3) telepharmacy, consisting of the evaluation of the inclusion of patients in a program of this type, course of the disease, and identification of the contact with the pharmacy service; (4) non-pharmacological treatment and patient information. To decide its potential inclusion in the checklist, 2 rounds of the Delphi were carried out in which the panelists had to assess the degree of agreement of each proposed item according to its "utility", which was the determining criterion for its inclusion, and its "applicability". RESULTS: Forty-eight hospital pharmacists were contacted, 30 (63%) agreed in writing to participate, 28 (58%) completed the first round of the Delphi, and 27 (56%) completed the second round. After the first round of the Delphi, the questionnaire was amended and comprised 40 items. Of the 40 items evaluated after the 2 rounds of the Delphi, there were 2 that, based on utility, the participants did not reach consensus for inclusion in the checklist: the one referring to "History of surgical intervention, specifically abdominal surgery in the last 4 weeks" (finally kept on the checklist due to its involvement in the indication of nintedanib) and to make recommendations on "Relaxation". No consensus was reached on their applicability for 2 of the items: "Patient stratification according to the Spanish Society of Hospital Pharmacy (SEFH) chronic patient model" and "Collection of Results Reported by the Patient". CONCLUSIONS: The management of patients with ILD and/or pulmonary fibrosis is complex and requires a multidisciplinary approach where the hospital pharmacist plays a key role, especially, although not only, in monitoring drug treatment. We believe that this checklist can contribute from pharmaceutical care to improving the integrated care of patients with ILD who require or are undergoing treatment with antifibrotic drugs.

OBJECTIVE: The objectives are to know the opinion of neurologists and hospital pharmacists on those aspects still under debate regarding the role of anti-Calcitonin Gene-related Peptide monoclonal antibodies in the preventive treatment of migraine. To identify those controversies that still exist. To propose agreed recommendations for improvement of care. And to promote access of clinicians and patients to these new treatments in the prevention of migraine with biological drugs, in order to improve patient care and follow-up. METHODOLOGY: Recommendations for the use of biological drugs in the prevention of migraine were identified and evaluated through the Delphi consensus methodology, proposing 88 statements grouped into 3 themes: a clinical module that deals with the management of biological treatments in migraine; a patient module that discusses patient education and adherence improvement strategies; and a coordination module that includes statements related to strategies to improve joint work between the two groups. The 9-point Likert ordinal scale was used to score these recommendations and, subsequently, the data was statistically analysed through different metrics. RESULTS: After both rounds of voting, consensus was reached in agreement on 71 of the 88 statements (80.7%), leaving 1 statement (1.1%) with consensus in disagreement and 16 remaining as indeterminate (18.2%). CONCLUSIONS: The high degree of consensus indicates that the opinion of neurologists and hospital pharmacists on the role of anti-Calcitonin Gene-related Peptide monoclonal antibodies in the preventive treatment of migraine is very similar and allows identifying those controversies that still exist, to improve the care and follow-up of patients with migraine.

BACKGROUND: This article reviews the available scientific literature on drug-related problems and negative outcomes associated with medications identified by medication review with follow-up for end-stage renal disease and discussed with the physicians. METHODS: A systematic review was conducted of the scientific literature retrieved from the following databases: MEDLINE (via PubMed), Web of Science, SCOPUS, Cochrane Library: The Cochrane Central Register and Control Trials (CENTRAL) and Literatura Latinoamericana y del Caribe (LILACS), Medicina en Español (MEDES), and the SciELO bibliographic database (a collection of scientific journals). The following terms were used as descriptors and searched in free text: "end-stage renal disease", "medication review", "drug-related problems", and "negative outcomes associated with medication". The following limits were applied: "humans" and "adults (more than 18 years)". RESULTS: A total of 59 references were recovered and, after applying inclusion/exclusion criteria, 16 articles were selected. Of these selected articles, 15 provided information on drug-related problems and only 1 on negative outcomes associated with medications. CONCLUSIONS: It can be concluded that drug-related problems and negative outcomes associated with medications affect patients with end-stage renal disease, mainly those receiving renal replacement therapy. More evidence is needed, especially on negative outcomes associated with medication.
RESUMEN
OBJECTIVES: To analyze the evolution of clinical outcomes derived from clinical trials on first-line therapies for advanced or metastatic non-small cell lung cancer (NSCLC) published between 2010 and 2020, focusing on how these outcomes impact survival rates and management of patients. METHODS: A systematic review of phase III and pivotal phase II clinical trials was conducted by a structured search on Medline and Embase. A comprehensive set of variables was collected to assess their influence on survival rates. We also estimated the clinical benefit by applying the ESMO-MCBS v1.1 and extracted the authors' conclusions. RESULTS: Sixty-six studies involving 34,951 patients were included. Best survival outcomes were found for nonsquamous non-small cell lung cancer (OS and progression-free survival medians: 19.4 and 10.2 mo) and for those expressing molecular targets (OS and progression-free survival medians: 23.8 and 11.0 mo). No significant influence on survival rates was observed for industry funding and disease stage (IIIB/IV vs. IV). ESMO-MCBS v1.1 was applied in 45 positive studies and resulted in a meaningful clinical benefit score in 37.8%. Quality of life (QoL) was reported in 57.6% of the original publications and showed statistical significance favoring the experimental arm in 33.3%. Positive authors' conclusions (75.7% of trials) were based on OS and/or QoL in 34% and on surrogate endpoints in 66%. CONCLUSIONS: Extended survival times and a steady improvement in QoL have been observed. However, there were more than twice as many studies reporting positive authors' conclusions as studies meeting the ESMO threshold for meaningful clinical benefit.

OBJECTIVE: To determine the value contribution of cabotegravir + rilpivirine, the first injectable every two months long-acting antiretroviral regimen, using multi-criteria decision analysis. METHOD: The study was developed in two phases. After a small pilot, a field ork study with a larger number of multidisciplinary experts was carried out. Seven single-tablet regimens, currently recommended by the GeSIDA guidelines, were selected as comparators. EVIDEM methodology was followed, with a framework composed by 12 quantitative and 5 contextual criteria. Mean and standard deviations were calculated for quantitative criteria (1 to 5 scale; comparative criteria -5 to +5), whereas qualitative criteria were analyzed as percentages of experts that considered a positive, neutral or negative impact for the National Health System. RESULTS: 35 experts participated in the study. Human immunodeficiency virus- 1 infection was considered severe (mean ± standard deviation: 3.0 ± 1.0), with moderate size of affected population (2.7 ± 1.2) and unmet needs (2.8 ± 1.0). Minimal differences were found in comparative efficacy/effectiveness (0.1 ± 0.5), safety/tolerability (-0.5 ± 0.7), and cost criteria: cost of the intervention (0.5 ± 2.0), other medical costs (0.2 ± 1.8) and non- medical/indirect costs (0.5 ± 1.6). Experts perceived an improvement with cabotegravir + rilpivirine long-acting, compared to current daily oral single-tablet regimens, in patient-reported outcomes (2.7 ± 1.4). Therapeutic benefit of the long-acting regimen was considered moderate-to-high (3.5 ± 1.2). Experts considered the evidence provided by cabotegravir + rilpivirine long- actingrobust (4.3 ± 0.8), with elevated consensus on its future recommendation in guidelines (3.2 ± 1.0). In contextual criteria, most experts considered positive the impact on population priorities and access (91%), common goal and specific interests (63%) and political, historical, and cultural context criteria (60%). Impact was neutral in system capacity and appropriate use (40%), and opportunity costs and affordability criteria (51%). Result of the weighted global value contribution of cabotegravir + rilpivirine long-acting was 0.34 (-1 to +1 scale), with Patient Reported Outcomes comparative criterion bringing the highest added value. CONCLUSIONS: Cabotegravir + rilpivirine long-acting provides added value contribution to human immunodeficiency virus-1 management in Spain compared to daily oral single-tablet regimens. Patient Reported Outcomes and therapeutic benefit of cabotegravir + rilpivirine long-acting were highly valued by experts, as the expected benefit in adherence and stigma-related issues would improve overall quality of life for people living with human immunodeficiency virus-1.
OBJETIVO: Determinar la contribución de valor de cabotegravir + rilpivirina, el primer tratamiento antirretroviral inyectable de acción prolongada, utilizando metodología de análisis de decisión multicriterio.Método: El estudio se desarrolló en dos fases: una prueba piloto y una fase de extensión, con un grupo multidisciplinar más grande. Se seleccionaron siete regímenes de comprimido único orales diarios recomendados en las guías GeSIDA como comparadores. Se utilizó el marco EVIDEM, compuesto por 12 criterios cuantitativos y 5 contextuales. Los criterios cuantitativos se analizaron calculando la media y desviación estándar, y los cualitativos se analizaron mediante el porcentaje de expertos que consideraron el impacto positivo, neutro o negativo para el Sistema Nacional de Salud. RESULTADOS: Un total de 35 expertos participaron en el estudio. La infección por virus de la inmunodeficiencia humana 1 se consideró grave (media ± desviación estándar: 3,0 ± 1,0), con un tamaño de población afectada (2,7 ± 1,2) y unas necesidades no cubiertas (2,8 ± 1,0) moderadas. Las diferencias fueron mínimas en los criterios comparativos de eficacia/efectividad (0,1 ± 0,5), seguridad/tolerabilidad (0,5 ± 0,7) y coste: coste del tratamiento (0,5 ± 2,0), otros costes médicos (0,2 ± 1,8) y costes no-médicos/indirectos (0,5 ± 1,6). Los expertos observaron una emtrimejora con cabotegravir + rilpivirina de acción prolongada en los resultados reportados por los pacientes (2,7 ± 1,4). El beneficio terapéutico (3,5 ± 1,2) se consideró moderado-alto. La evidencia de cabotegravir + rilpivirina de acción prolongada fue considerada robusta (4,3 ± 0,8), con elevado consenso sobre su futura recomendación en las guías (3,2 ± 1,0). En los criterios contextuales, el impacto fue positivo en los criterios de prioridades de acceso (91%), objetivo común (63%) y contexto político (60%). El impacto fue neutro en la capacidad del sistema (40%) y los costes de oportunidad (51%). El resultado promedio de la contribución del valor global de cabotegravir + rilpivirina de acción prolongada fue de 0,34 (escala de 1 a +1), siendo el criterio de resultados reportados por el paciente el que proporcionó la mayor contribución de valor (0,04). CONCLUSIONES: Cabotegravir + rilpivirina de acción prolongada aporta un valor añadido en el manejo del virus de la inmunodeficiencia humana 1 en España en comparación con los regímenes de comprimido único utilizados actualmente. Los expertos valoraron positivamente los resultados reportados por los pacientes y el beneficio terapéutico de cabotegravir + rilpivirina de acción prolongada, considerando que el beneficio esperado en la adherencia y los problemas relacionados con el estigma produciría una mejora en la calidad de vida de las personas con virus de la inmunodeficiencia humana 1.

Antibiotics remain one of the main treatment alternatives in mild-to-moderate hidradenitis suppurativa. The use of topical 15% resorcinol reduces antibiotic pressure and the generation of resistance. However, knowledge on its efficacy and safety is limited. This single-center, prospective, follow-up cohort study evaluated topical 15% resorcinol every 12-h response at 16 weeks. Those individuals with mild-to-moderate hidradenitis suppurativa (Hurley I-II) who started treatment with topical resorcinol monotherapy between April 2019 and May 2020 were eligible for follow-up. The primary endpoint for effectiveness was the proportion of patients who achieved an overall clinical response (complete or partial response) at week 16, evaluated as intention-to-treat. Responses were measured according to the Hidradenitis Suppurativa Clinical Response index. Target lesion size was measured clinically and by ultrasonography. Quality of life was assessed through the Dermatology Life Quality Index (DLQI) questionnaire. Safety was measured by recording the adverse events reported during the follow-up period. A total of 32 patients were enrolled (mean age, 40.1 years [95% confidence interval, 35.7-44.4]; women, 20 [62.5%]; Hurley I, 17 [53.1%]). Under the intention-to-treat analysis, 68.8% (n = 22) of the patients achieved a clinical response. A ≥50% reduction in the size of the main lesion was observed in 56.3% of the patients (n = 18). Some 65.6% (n = 21) of the patients had a ≥50% reduction (improvement) in their baseline DLQI score. Fifty percent of patients who completed the follow-up period experienced adverse events, all of which were local, mild, and transient and did not lead to discontinuation of resorcinol. To conclude, in this cohort study, topical 15% resorcinol was shown to be effective for mild-to-moderate hidradenitis suppurativa and to have a positive impact on quality of life with an acceptable safety profile.

BACKGROUND: The World Health Organization declared COVID-19 a pandemic in March 2020. The first vaccine became available in December, with practically no post-marketing data. METHODS: An analytical cross-sectional survey-based study was conducted in a third-level hospital in Spain between March and April 2021 to describe the difference in adverse events with the BNT162b2 and mRNA-1273 COVID-19 vaccines. The participants were hospital workers who completed a survey voluntarily at least 14 days after the last vaccine. The STROBE checklist was followed. RESULTS: One thousand two hundred and forty-nine respondents completed the survey; 48% (599) received mRNA-1273 and 52% (650) BNT162b2. Fourteen thousand four hundred and two adverse reactions were recorded, 6896 local (3939 with mRNA-1273 and 2957 with BNT162b2 (6.6 vs 4.4 reactions per patient)) and 7506 systemic (4460 with mRNA-1273 and 3046 with BNT162b2 (7.4 vs 4.7 per patient)). Local reactions were more frequent after the first dose, while systemic reactions were higher after the second, for both vaccines and in a higher percentage with mRNA-1273 compared to BNT162b2 (p-value<0.05). CONCLUSIONS: Licensed mRNA vaccines were highly safe when administered under post-marketing conditions among working-age adults. The main adverse events were mild, although they occurred in most patients, especially after the mRNA-1273 vaccine.

A new subcutaneous formulation of the infliximab biosimilar CT-P13 has recently been developed for the treatment of inflammatory bowel disease (IBD), providing response rates similar to intravenous treatment. The use of this new formulation was requested, in an effort to limit patient attendance at intravenous infusion centers and to maintain biological treatment during the COVID-19 pandemic. The objective of this observational, retrospective and descriptive study was to assess CT-P13 efficacy and safety after switching from intravenous to a subcutaneous formulation in patients with IBD receiving maintenance therapy. This article shows preliminary results after six months of follow-up.

OBJECTIVES: Topical resorcinol 15% is a self-treatment for painful hidradenitis suppurativa nodules and abscesses with good results in reducing pain and lesion duration. The aim of this study is to establish a 15% topical resorcinol formula, to develop a physicochemical and microbiological stability study and to further determine the compounding shelf-life in different package conditions following the European Pharmacopoeia (Ph. Eur.) specifications. METHODS: Physicochemical and microbiological stability studies of the formulation were conducted for 12 months at room temperature (25°C±2°C) in different package conditions: aluminium tubes (aluminium A7-99.7% varnish DF-6172), plastic tubes (low density polyethylene) and amber plastic containers (polyethylene terephthalate). High performance liquid chromatography (HPLC) was developed as a method of indicating the stability of the resorcinol formulation. A microbiological growth assay was also validated according to the Ph. Eur. Physical properties were inspected to determine parameters such as odour, colour, pH, emulsion phase and extensibility index and its evolution. RESULTS: The HPLC method was validated according to the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidelines. At day 365, visual inspection remained unchanged only for preparations packaged in aluminium tubes. The pH did not vary by more than 0.3 units in all conditions. The extensibility index decreased in the preparations packaged in plastic and amber plastic containers. HPLC analysis conducted over 1 year did not show a degradation greater than 7% of resorcinol in the preparation in plastic and aluminium packages. The ability of ATCC strains to grow in resorcinol formulation was confirmed under the suitability test. Resorcinol packed in aluminium tubes achieved microbiological stability at day 365. CONCLUSIONS: Only the formulation package in aluminium tubes showed physicochemical and microbiological stability of resorcinol for 12 months at room temperature (25°C±2°C).

OBJECTIVE: To evaluate the impact of discontinuation of treatment with cholinesterase inhibitors (ChEIs) on cognitive, behavioural and functional outcomes in patients with severe dementia. METHODS: A prospective observational study in which the prescribing physician decides, depending on multidisciplinary assessment and following the recommendations of the clinical practice guidelines, whether to withdraw or continue ChEI treatment in institutionalised patients, with a follow-up of 3 months. Cognitive abilities were measured using the Mini-Mental State Examination (MMSE) and Reisberg's Global Deterioration Scale (GDS). Other measures were the behavioural and psychological symptoms of dementia (BPSD) according to the Neuropsychiatric Inventory (NPI), the activities of daily living using the Barthel index, the pharmacological and the non-pharmacological measures to treat the BPSD. RESULTS: ChEI treatment was discontinued in 23 of 43 patients. After 3 months there were no differences in MMSE (p=0.441), GDS (p=0.976), NPI (p=0.882) or Barthel index (p=0.080) scores, or the establishing of new pharmacological measures (p=0.919) or non-pharmacological measures (p=0.832). CONCLUSIONS: ChEI discontinuation in advanced stage dementia was not related to clinical deterioration in terms of cognitive function, BPSD, or functional status. Discontinuing ChEI treatment according to a multidisciplinary assessment and the recommendation of the guidelines appears to be a possible way of optimising pharmacotherapy without altering the main clinical evaluation scales.

Breast cancer (BC) is the most frequent neoplasm and one of the main causes of death in women. The pharmacological treatment of BC consists of hormonal therapy, chemotherapeutic agents and targeted therapy. The response to BC therapy is highly variable in clinical practice. This variability can be explained by the presence of genetic polymorphisms in genes involved in the pharmacokinetics, pharmacodynamics or immune response of patients. The abundant evidence of associations between low-activity alleles CYP2D6*3, *4, *5, *6, *10 and *41 and poor results with tamoxifen therapy, and between DPYD gene polymorphisms rs3918290, rs55886062, rs67376798 and rs75017182 and increased risk of toxicity to fluoropyrimidine therapy, justify the existence of clinical pharmacogenetic guidelines. The NQO1 rs1800566 polymorphism is related to poorer results in BC therapy with chemotherapy agents. The polymorphism rs1695 of the GSTP1 gene has been associated with the effectiveness and toxicity of fluorouracil, cyclophosphamide and epirubicin therapy. Finally, the HLA-DQA1*02:01 allele is significantly associated with the occurrence of liver toxicity events in patients receiving lapatinib. There is moderate evidence to support the aforementioned associations and, therefore, a high probability of these being considered as future predictive genetic biomarkers of response. However, further studies are required to reinforce or clarify their clinical relevance.

OBJECTIVE: Hospital pharmacy services have adapted to the COVID19 pandemic. The aim of the study is to determine the economic consequences of replacing hospital pharmacy dispensation with other dispensing methods in the context of biological treatments for psoriasis in Spain. METHOD: Multiple dispensation scenarios were evaluated, combining different dispensation frequencies and sites, and telepharmacy followup intervals. Self- injectable biological medicines for psoriasis (interleukin and tumour necrosis factor alpha inhibitors) were included. All costs (in 2020 euros) were considered from the perspective of the National Health System. RESULTS: The annual cost of hospital pharmacy-based dispensations every 4 weeks combined with telepharmacy monitoring at each administration ranged from 194.9 to 2,088.0 per patient. Across the different simulated scenarios, biological medicines associated with the lowest cost were those administered less frequently (every 12 weeks). CONCLUSIONS: In the post-COVID-19 era, new models of hospital pharmaceutical care that include changes in drug dispensation and telepharmacy strategies will have economic consequences for the National Health System that merit consideration.
Objetivo: Los servicios de farmacia hospitalaria se han adaptado a la pandemia de COVID-19. El objetivo del estudio es determinar las consecuencias económicas de sustituir la dispensación de medicamentos en el servicio de farmacia hospitalaria por otros métodos de dispensación en el contexto de los tratamientos biológicos para la psoriasis en España.Método: Se evaluaron múltiples escenarios de dispensación, combinando diferentes frecuencias y lugares de dispensación, y frecuencias del seguimiento de telefarmacia. Se incluyeron los medicamentos biológicos autoinyectables para la psoriasis (inhibidores de interleucinas y del factor de necrosis tumoral alfa). Todos los costes (euros de 2020) se consideraron desde la perspectiva del Sistema Nacional de Salud.Resultados: Considerando la dispensación en la farmacia hospitalaria, la frecuencia de dispensación cada 4 semanas y la telefarmacia en cada administración, el coste anual de dispensación por paciente osciló entre 194,9 y 2.088,0 . En los diferentes escenarios simulados, los fármacos biológicos que se asociaron a un coste inferior fueron los que se administran de forma más espaciada en el tiempo (cada 12 semanas).Conclusiones: En la era post-COVID-19, los nuevos modelos de atención farmacéutica hospitalaria que consideran cambios en la dispensación farmacológica y la telefarmacia tendrán consecuencias económicas para el Sistema Nacional de Salud que merecen consideración.

First-line therapy with interferon beta (IFN-ß), involved in gene expression modulation in immune response, is widely used for multiple sclerosis. However, 30-50% of patients do not respond optimally. Variants in CBLB, CTSS, GRIA3, OAS1 and TNFRSF10A genes have been proposed to contribute to the variation in the individual response. The purpose of this study was to evaluate the influence of gene polymorphisms on the IFN-ß response in relapsing-remitting multiple sclerosis (RRMS) patients. CBLB (rs12487066), GRIA3 (rs12557782), CTSS (rs1136774), OAS1 (rs10774671) and TNFRSF10A (rs20576) polymorphisms were analysed by Taqman in 137 RRMS patients. Response to IFN-ß and change in the Expanded Disability Status Scale (EDSS) after 24 months were evaluated using multivariable logistic regression analysis. Carriers of at least one copy of the C allele of CTSS-rs1136774 had a better response to IFN-ß (p = 0.0423; OR = 2.94; CI95% = 1.03, 8.40). Carriers of TT genotype of TNFRSF10A-rs20576 had a higher probability of maintaining their EDSS stable after 24 months of IFN-ß treatment (p = 0.0251; OR = 5.71; CI95% = 1.39, 31.75). No influence of CBLB (rs12487066), OAS1 (rs10774671) and GRIA3 (rs12557782) gene polymorphisms in the variation of the individual response to IFN-ß was shown. Our results suggest that the TNFRSF10A-rs20576 and CTSS-rs1136774 gene polymorphisms influence the response to IFN-ß after 24 months, while the CBLB (rs12487066), OAS1 (rs10774671) or GRIA3 (rs12557782) gene polymorphisms had no effect on the variation of the individual response to IFN-ß.

BACKGROUND: Despite newer therapies, advanced or metastatic non-small-cell lung cancer (NSCLC) continues to be the leading cause of cancer-related deaths worldwide. Deficits in the design and methods of randomized controlled trials (RCTs) may contribute to reducing the clinical benefit of therapies in oncology. To prioritize treatments based on efficacy results and toxicity data, the European Society for Medical Oncology (ESMO) has developed the Magnitude of Clinical Benefit Scale (MCBS). The objective of this study was to apply the ESMO-MCBS v1.1 to a cohort of RCTs on therapies for advanced or metastatic NSCLC. MATERIAL AND METHODS: Phase III and pivotal phase II trials, published between 2013 and 2018, investigating drug therapies for advanced NSCLC were included. PubMed was specifically searched for efficacy/toxicity updates. Treatments were graded 5 to 1 on the ESMO-MCBS v1.1, using the lower limit of the 95% confidence interval of the hazard ratio (HR), where scores 5 and 4 represent a substantial clinical benefit. Additionally, scores using the point estimate HR were generated, for comparison. Discrepancies between our grade estimations and the ones published on the ESMO website, as scorecards, were identified. RESULTS: ESMO-MCBS scores were calculated for 42 positive clinical trials. 54.8% met the ESMO-MCBS thresholds for clinically meaningful benefit (final grade of 4 or 5). That percentage decreased to 40.5% when considering the point estimate of the HR. 50.0% of the trials had no published scorecard on the ESMO website and discrepancies affected 11 (26.2%) studies. CONCLUSION: Almost half of the RCTs showing a statistically significant result favoring the experimental arm, failed to demonstrate a substantial clinical benefit according to the ESMO framework.
