Great recognition to a fundamental discovery that reshaped modern #immunology. Congrats to the laureates!
However, imho the Nobel committee missed the chance to acknowledge an additional key contributor to the understanding of #Foxp3 and #Treg functionality

Fantastic evening supporting the first lecture organized by #CaixaResearchInstitute and catching up with many colleagues! It’s always inspiring to hear Gabi as he guides us through a ‘sweet’ path at the intersection of #glycobiology and #immunology with tremendous potential for human diseases.

The PCSK9-targeting epigenetic editor led to rapid and sustained 90% reduction of PCSK9 protein, resulting in a clinically meaningful 70% reduction in LDL-C in non-human primates

The human PCSK9-targeting #epigenetic editor packaged into an #LNP was able to reduce circulating PCSK9 protein 98% for a year after a *single administration* in a human PCSK9 transgenic mouse 🤯

ctDNA analysis revealed that a single dose of CAR-M induced robust *but transient* anti-tumor activity in patients with HER2 3+ tumors. Encouraging early data from this FIH, the field should build upon it!

$CARM has undergone a strategic restructuring, focusing on in vivo CAR-M generation (relying on its ongoing collaboration w Moderna to exploit mRNA/LNPs) and shifting toward #fibrosis, #oncology and #autoimmunity

Are we facing a new gold standard for intermediate stage #HCC? Lenvatinib (multi TKI) + pembrolizumab, combined with transarterial chemoembolisation (TACE), outperforms TACE alone (SoC) in PFS in a global, randomized, double-blind Phase 3 trial.

Promising data in #IBD! Duvakitug, an anti-TL1A mAb, delivered positive Phase 2b results in moderate-to-severe ulcerative colitis and Crohn’s disease.
Co-developed by Teva and Sanofi, a Phase 3 trial led by Sanofi is expected to kick off in 2025.

$PSTX platform includes non-viral capabilities to design, develop and manufacture #allogeneic, T stem cell memory-rich #CART therapies. The acquisition will establish a new capability for Roche in allogeneic #celltherapy, with CAR-T programs in hemato malignancies, solid tumors & autoimmune diseases

Kate’s 'Directed Evolution of #AAV Capsid Leveraging In Vivo Expression of Transgene RNA' (DELIVER) platform has been used to evolve a novel class of liver de-targeted muscle-tropic capsids, which transduce skeletal muscle & cardiac tissue with potency & selectivity in vivo, while avoiding the liver

Keytruda accounted for $25B of Merck’s $60B in revenue last year, when it became the world’s best-selling #medicine. But there is still room for improvement, as most patients don’t durably respond to ICBs. Keytruda is facing patent cliff in 2028, and $MRK will be pressed to replace lost revenues
