Claudins - The Next Big Solid Tumor Target? A major 2026 review in Nature Reviews Cancer dissects why CLDN proteins are rapidly emerging as precision oncology targets Here’s what every oncologist should know: 🧬 What are Claudins? Tight junction transmembrane proteins maintaining epithelial polarity. Frequently dysregulated and overexpressed across solid tumors. 🔥 Why they matter in cancer •Promote proliferation •Drive EMT & stemness •Modulate fibrosis •Shape immune microenvironment •Contribute to therapeutic resistance 🎯 Therapeutic breakthrough CLDN18.2 targeting has achieved regulatory approval - validating claudins as druggable surface antigens 🚀 Therapeutic platforms in development •Monoclonal antibodies •ADCs •Bispecific antibodies •CAR-T cells •Intracellular pathway targeting 🧠 Precision angle Surface overexpression + subtype correlation + biomarker-enriched selection = scalable solid tumor strategy. Claudins may follow the HER2 playbook. From barrier proteins to immunotherapy targets. 📖 Full review: Nature Reviews Cancer 2026 #OncoTwitter #MedTwitter #PrecisionOncology #Immunotherapy #TargetedTherapy #GastricCancer #GIOncology #SolidTumors #ADC #CART @NatureRevCancer @ASCO @myESMO @OncoAlert @ESMO_Open



When New England Journal publishes a phase I trial...you know its something interesting TP53 Y220C Reactivator: Rezatapopt > 7 out of 15 evaluable patients with ovarian cancer had responses and prolonged ones at that (see below) > The most common AEs: nausea, vomiting, anemia > Serious AEs with this novel strategy included pneumonitis, pyrexia, ALT/AST elevation and AKI -> clearly a lot to learn One interesting point was 4 patients underwent biopsies on progression and one of the 4 had two new TP53 variants – this is early data and hard to draw any conclusions but with any novel therapies have to make sure we aren’t breeding more resistant clones with our treatments – time will tell #Gynonc @OncLive
