Efficacy and Safety of Erenumab, Galcanezumab, and Fremanezumab in the Treatment of Drug-Resistant Chronic Migraine: Experience in Real Clinical Practice.

BACKGROUND: Due to the recent introduction of new biologic drugs for chronic migraine, a global evaluation in real clinical practice is necessary. OBJECTIVE: The objective was to evaluate the effectiveness and safety in real clinical practice of drugs targeting the calcitonin gene-related peptide receptor (CGRPr) in patients with chronic migraine. METHODS: Single-center, restrospective study (2019-2022), including patients with chronic migraine treated with erenumab, galcanezumab, or fremanezumab. Effectiveness variables were recorded, namely, number of migraine headache days per month (MHD), Migraine Disability Assessment Scale (MIDAS) score, and Headache Impact Test-6 (HIT-6) score, assessing changes at week 12, 24 from baseline. Toxicity was recorded following the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 criteria. RESULTS: In all, 104 patients were included (46.2% erenumab, 41.3% galcanezumab, 12.5% fremanezumab). A reduction in MHD, MIDAS, and HIT-6 was achieved at weeks 12 and 24 with erenumab (p75% at week 24 than those intensified; P = 0.041). There was no difference in efficacy (P = 0.154) or improvement in quality of life (P = 0.783, P = 0.150), but there was greater toxicity (P < 0.001) among nonresponders with erenumab 70 mg versus erenumab 140 mg. CONCLUSIONS: The results confirm the effectiveness and safety of anticalcitonin gene-related peptide (CGRP) drugs in real clinical practice. However, the study shows little benefit from erenumab intensification, with similar effectiveness and worse tolerability than the standard dose.

Cost-effectiveness study of closed system transfer devices for the preparation of antineoplastic agents / Estudio coste-eficiencia de sistemas cerrados para la preparación de agentes antineoplásicos

Most cytostatic drugs cannot be administered directly to patients in their marketed presentation, but require previous reconstitution conducted in the Pharmacy Unit areas for cytostatic preparation. There are systems that allow drug reconstitution and transfer once it has been diluted, in order to protect staff from any potential contamination during handling. These are commonly known as Closed Systems, and generally have a piece for vial attachment and a syringe adapter with a built-in filter, that replace the traditional needles. Closed systems feature different characteristics and costs which is necessary to analyze in order to determine the most efficient one (AU)

La mayoría de fármacos citostáticos no pueden ser administrados directamente desde la presentación comercial al paciente, sino que requieren de una reconstitución previa realizada en las áreas de elaboración de citostáticos en los Servicios de Farmacia. Existen sistemas que permiten reconstituir y extravasar el fármaco una vez diluido, para evitar la posible contaminación derivada de su manejo al personal. Estos sistemas se conocen comúnmente como sistemas cerrados, y de manera genérica constan de una pieza de fijación al vial y un adaptador para la jeringa con filtro integrado, que sustituyen a las tradicionales agujas. Los sistemas cerrados presentan diversas características y costes que son necesarios analizar para conocer cuál es el sistema más eficiente (AU)
