BeOne Medicines Ltd., azienda oncologica a livello globale, ha annunciato oggi che la Commissione Europea ha approvato tislelizumab, in combinazione con gemcitabina e cisplatino, per il trattamento di prima linea dei pazienti adulti con carcinoma rinofaringeo (NPC) recidivante o metastatico, non suscettibile di intervento chirurgico o radioterapico curativo.

La gestione dell’infezione da HIV ha fatto enormi progressi, portando oggi la maggior parte delle persone con HIV in trattamento a raggiungere e mantenere una viremia non rilevabile. Tuttavia, l’efficacia della terapia antiretrovirale (ART) non è più il solo parametro da considerare: l’ottimizzazione della terapia è diventata fondamentale per garantire che il trattamento sia ben tollerato, sostenibile e adattato alle esigenze individuali, migliorando così l’aderenza e la qualità di vita del soggetto, in una prospettiva di successo a lungo termine.

Il panorama dell’immuno-oncologia si arricchisce di nuove prospettive grazie agli anticorpi trispecifici, molecole in grado di colpire simultaneamente tre diversi bersagli cellulari. È su questa promettente frontiera terapeutica che AbbVie ha deciso di investire, siglando un accordo da oltre 1,9 miliardi di dollari con IGI Therapeutics per ottenere i diritti esclusivi su ISB 2001, una terapia sperimentale destinata al trattamento del mieloma multiplo e, potenzialmente, di alcune malattie autoimmuni.

Dopo aver dimostrato la sua efficacia nel melanoma, il farmaco immunoterapico Daromun, iniettabile direttamente nella massa tumorale, sembra essere promettente anche nel trattamento dei tumori cutanei più diffusi: il carcinoma basocellulare e quello squamocellulare. I risultati preliminari di uno studio di fase II verranno discussi domani a Napoli in occasione della seconda edizione del congresso INNOVATE – International Neoadjuvant Immunotherapy Across Cancers

Nei pazienti con anemia emolitica autoimmune da anticorpi caldi (wAHIA), il trattamento con l’inibitore della tirosin chinasi di Bruton (BTK) rilzabrutinib è efficace, anche nel lungo termine, nel migliorare i valori di emoglobina (Hb), ridurre i biomarcatori di emolisi e migliorare la fatigue, con un buon profilo di sicurezza. Lo dimostrano i risultati di una nuova analisi dello studio di fase 2b LUMINA 2, con un periodo più lungo di osservazione, presentati di recente a Milano, in occasione del congresso annuale della European Hematology Association (EHA).

MSD ha annunciato l’acquisto di Verona Pharma per 10 miliardi di dollari. L’azienda ottiene così il controllo di Ohtuvayre (ensifentrina), un farmaco per il trattamento di mantenimento della broncopneumopatia cronica ostruttiva (BPCO). Il prezzo pattuito, 107 dollari per azione (american depositary shares), rappresenta un premio del 23% rispetto al prezzo di chiusura di martedì (86,86 dollari).

Nelle pazienti con carcinoma mammario metastatico, una nuova terapia ormonale mirata, elacestrant, ha ridotto il rischio di progressione o morte del 45%. L’Agenzia Italiana del Farmaco (AIFA) ha approvato la rimborsabilità di elacestrant per il trattamento di donne in postmenopausa, e di uomini, con carcinoma mammario localmente avanzato o metastatico positivo per i recettori degli estrogeni (ER+) e negativo per la proteina HER2 (HER2-), con una mutazione attivante del gene ESR1, che mostrano progressione della malattia in seguito ad almeno una linea di terapia endocrina comprendente un inibitore delle cicline CDK 4/6.

Al Congresso ICD 2025 sono stati presentati due studi che confermano l’efficacia duratura di bimekizumab nel trattamento della psoriasi a placche da moderata a severa, con risposte cliniche mantenute fino a quattro anni. I dati confermano inoltre tempi di risposta rapidi, con miglioramenti significativi già entro le prime settimane di trattamento.

Lecanemab became the first disease-modifying treatment for Alzheimer disease (AD) to receive traditional approval by the US Food and Drug Administration in 2023. Although the monoclonal antibody can remove amyloid-β plaques, the drug has been linked to brain changes known as amyloid-related imaging abnormalities (ARIA). A new study of patients with early symptomatic AD treated at an outpatient memory clinic suggests these and other adverse events are manageable in this population.

Poetry catalyzes memory, as other poems featured in JAMA have variously demonstrated. It is used directly among patients with dementia in programs such as the Alzheimer’s Poetry Project to reproducibly beneficial effect. “Missing Father” offers another example of the connections between poetry and memory. The poem both describes actual memories while at the same time seeming to spark more of them. The paradoxical double meaning of the title both reports on and grieves for the lost voice of the storyteller father—he is both absent and an actively yearned-for presence—while the first line’s immediacy of “this morning being” ironically unleashes vivid memories, from the sound of his voice “rising/from the worn pages” of a picture book to the uncanny word-picture of the speaker and her twin sister eagerly awaiting his return from work, “pajamas hanging on us/like wilted petunias.” The poem reanimates them all together as they chant the names of the book’s characters, simultaneously recalling both the tenderness of a distant childhood and enacting poetry’s mooted origins in the passing down of community wisdom through incantatory language. Yet even as poetry facilitates such recollection, and helps sustain the more practical, trying search for “nursing homes close and affordable,” ultimately it cannot bring back the long-gone, stricken father; instead, it becomes an act of healing, remembering that brighter time of more bearable loss, “a day when the only problem/was a carrot missing from/Mister McGregor’s garden.”

This trial investigates intrapartum sildenafil citrate to improve perinatal outcomes potentially related to intrapartum hypoxia in term pregnancies.

Introduction
There is a need for early, non-invasive and inexpensive biomarkers for Alzheimer’s disease (AD), which could serve as a proxy measure in prevention and intervention trials that might eventually be suitable for mass screening. People with Down syndrome (DS) are the largest patient group whose condition is associated with a genetically determined increased risk of AD. The REVEAL study aims to examine changes in the structure and function of the eye in individuals with DS compared with those with mild cognitive impairment (MCI) and cognitively healthy control (HC) individuals. REVEAL will also explore whether these changes are connected to inflammatory markers previously associated with AD.

Methods and analysis
The protocol describes a cross-sectional, non-interventional, single-centre study recruiting three cohorts, including (1) participants with DS (target n=50; age range, 6–60 years), (2) participants with MCI (target n=50; age range, 50–80 years) and (3) HC participants (target n=50; age range, 50–80 years). The primary research objective is to profile retinal, choroidal and lenticular status using a variety of eye imaging modalities and retinal functional testing to determine potential associations with cognitive status. The REVEAL study will also measure and compare established blood markers for AD and proteomic and transcriptomic marker profiles between DS, MCI and HC groups. Between-group differences will be assessed with an independent sample t-test and 2 tests for normally distributed or binary measures, respectively. Multivariate regression analysis will be used to analyse parameters across all three cohorts. Data collection began in October 2023 and is expected to end in October 2025.

Ethics and dissemination
The study gained a favourable opinion from Health and Social Care Research Ethics Committee A (REC reference 22/NI/0158; approved on 2 December 2022; Amendment 22/0064 Amend 1, 5 April 2023; Amendment 22/0064 Amend 2; 23 May 2024; Amendment 22/0064 Amend 3; 25 June 2024; Amendment 22/0064 Amend 4; 16 January 2025; Amendment 22.0064 Amend 5; 9 May 2025; Amendment 22.0064 Amend 6; 9 June 2025). The study has also been reviewed and approved by the School of Biomedical Sciences Research Ethics Filter Committee within Ulster University. Findings from the REVEAL study will be presented to academic audiences at international conferences and peer-reviewed publications in targeted high-impact journals after data collection and analysis are complete. Dissemination activities will also include presentations at public events.

Delirium affects one-third of hospitalized older adults and is associated with prolonged length of stay, institutional discharge, long-term functional and cognitive decline, Alzheimer disease and related dementias (AD/ADRD), and death. Moreover, the costs of delirium exceed $182 billion annually in the US alone. Despite these compelling data, accurate identification of delirium remains challenging, with more than half of delirium going unrecognized in routine care. While delirium prevention has advanced substantially, delirium treatment, which relies on early and accurate identification, lags. More than 40 tools are available for delirium assessment, ranging from short structured screens to in-depth reference standards. Evidence on how to implement these tools to improve delirium identification at the bedside, including which tool to use, who should administer it, how often, and how to educate and engage the care team, remains limited.

This Viewpoint examines the use of blood-based biomarkers to test for Alzheimer disease and outlines why they should not be the first or only tool used in screening for cognitive impairment.
