Here’s a polished LinkedIn-style post based on current 2026 anti-tau developments:
Anti-Tau Therapies Are Entering a New Era in Alzheimer’s Research
Recent 2026 updates are reinforcing tau as one of the most important therapeutic targets in Alzheimer’s disease, with development moving beyond traditional antibodies toward a broader mix of gene-silencing, anti-MTBR antibodies, combination therapy, and gene therapy.
At AAIC 2026, Biogen reported that diranersen (BIIB080), an antisense oligonucleotide targeting MAPT mRNA, produced robust reductions in CSF tau and brain tau pathology in the Phase 2 CELIA study, together with signals of slowed clinical decline. Biogen plans to advance the program into Phase 3 development. Biogen
Meanwhile, etalanetug (E2814) is targeting the microtubule-binding region of tau. Eisai reported substantial reductions in the tau-tangle biomarker eMTBR-tau243, and the antibody is being studied both in dominantly inherited Alzheimer’s disease and in combination with lecanemab in early sporadic disease.

Other approaches are also expanding the field. BMS-986446 is in Phase 2 development as another anti-MTBR-tau antibody and has received FDA Fast Track designation, while Voyager’s VY1706 is taking a gene-therapy approach designed to reduce intracellular and extracellular tau after a single IV dose.

Together, these programs point toward a more diversified future for Alzheimer’s treatment—one where tau may be targeted through multiple mechanisms and potentially combined with anti-amyloid therapies to address different stages of disease biology.
