Trelinjekombination med avutometinib, abemaciclib och fulvestrant erbjuder en väg förbi CDK4/6-resistens vid hormonreceptorpositiv metastaserande bröstcancer. I fase I-försöket tål 16 patienter (median ålder 61 år, 88 % viscerala metastaser) kombinationen utan allvarliga biverkningar. Den rekommenderade dosen för fas II är abemaciclib 100 mg två gånger dagligen, avutometinib 3,2 mg två gånger veckovis och fulvestrant 500 mg intramuskulärt var 28:e dag. Vanliga biverkningar var kreatinfosfokinas-förhöjning (50 %), neutropeni (50 %), diarré (44 %) och hudutslag (44 %). Objektiv respons nåddes hos 13 procent, klinisk nytta hos 40 procent efter 24 veckor. Mediän progressionsfri överlevnad var 3,6 månader. Dana-Farber Cancer Institute driver studierna tillsammans med UCLA och Biovica. Fas II pågår — viktig milstolpe för inköpschefer och läkemedelsinvesterare som värderar pipeline för tredje linjekombinationer.

Lungskador från mekanisk ventilation (VILI) utvecklas snabbare och svårare när lungvävnaden redan är skadad. Svenska och tyska forskare har nu kartlagt varför genom att kombinera 4D-bildbehandling och nanoskala mekaniska mätningar. Studien jämförde friska rattlungor med lungor som först skadats av bleomycin. Resultaten visade att extracellulär matris remodellering förändrar hur lungorna reagerar på injurious ventilation — luftrummen förstorades mest när skada redan fanns. Atomic force microscopy avslöjade region-specifika mekaniska svar, och den rumsliga analysen koplade nanoskala styvhet direkt till klinisk lungmekanik. För intensivvårdsenheter betyder detta att ventilationsstrategier måste anpassas efter lungvävnadens struktur. Regulatoriska myndigheter får empirisk grund för att revidera VILI-riskbedömning. MedTech-företag kan utveckla ventilatoralgoritmer som detekterar matrisförändringar tidigare än dagens metoder.

Dagens ANCA-associerad vaskulit-studier använder ändpunkter som inte fullt ut fångar patientnytta och kan dölja behandlingseffekter som är relevanta för klinisk praxis. Forskargruppen från Innsbruck, Linköping, Zagreb, Karolinska och Charité ifrågasätter om befintliga studiedesigner lämpar sig för att bedöma nya terapier eller om de missar båtvägen mot bättre diagnostiska och prognostiska verktyg. Implikationen är betydande för produktcykler inom nefrologisk behandling. Regulatorer och läkemedelsutvecklare måste klargöra vilka ändpunkter som gynnar både patients kliniska utfall och regulatoriskt godkännande — det finns spänning mellan snabba registreringar och meningfull effektmätning. För inköpschefer och sjukhusläkare innebär detta att framtida behandlingsalternativ bör utvärderas kritiskt mot gamla studieprotokolls begränsningar snarare än deras namn och renommé.

Goteborgsforskarnas studie identifierar blodbaserade biomarkörer för genetisk frontallobsdemens (FTD) — ett fynd som kan accelerera utvecklingen av patientspecifika behandlingsstrategier. Forskargruppen analyserade 124 hjärnrelaterade proteiner i plasma från 109 individer, varav 67 bar mutationer i GRN- eller C9orf72-generna. Neurofilament light (NfL) visade den starkaste förändringen i båda genotyperna, medan glial fibrillary acidic protein (GFAp) och VCAM1 endast förändrades vid GRN-mutation och korrelerade med sjukdomsvårleksgrad. Neuronal pentraxin receptor (NPTXR) reducerades selektivt vid C9orf72-FTD. Om resultaten valideras i oberoende kohorter kan dessa biomarkörer möjliggöra tidigare diagnostik, mer träffsäker patientstratifiering för kliniska prövningar och monitorering av sjukdomsprogression — kritiska faktorer för regionala hälsovårdscentraler som planerar diagnostiska investitioner.
