$IONS Zilganersen's commercial success hinges primarily on execution beyond the trial rather than its strong clinical evidence. The real bottleneck isn't payer resistance—it's the diagnostic challenge. Patients frequently misdiagnosed as multiple sclerosis or atypical parkinsonism, getting an accurate diagnosis remains the biggest obstacle to reaching potential patients and driving revenue. $BIIB $SRPT $BMRN #AlexanderDisease Read more: www.clinicaltrialsdaily.com/zilganersen-aso-alexander-disease-pdufa/

Cramer's lightning round $BIIB Biogen: “I read the upgrade today by Wells Fargo, and it talked about a bunch of revenue streams, including Alzheimer’s, and it was very impressive.

Shares of $BIIB have outperformed the market in 14 of the past 20 periods between April 18 and July 26. $IBB

$INMB Massive Paradigm Shift in Alzheimer's! The new Cochrane Review (CD016297) just dealt a devastating blow to the anti-amyloid hypothesis. 🚫 Gold-standard data from 42 trials shows that drugs like $LEMB and $BIIB clear plaque but fail to deliver meaningful cognitive benefits, while carrying serious safety risks like brain swelling (ARIA). 🤯 The market narrative is crumbling. Enter $INMB. Their lead asset, XPro™, targets neuroinflammation (soluble TNF), not amyloid. Cochrane's expert recommendation is clear: "Future research... should focus on other treatments." 💡 INmune Bio is the necessary evolution that Cochrane is inadvertently calling for. Structurally de-risked and perfectly positioned with XPro™ moving into pivotal trials with a biomarker-enriched design. Time to look beyond the failed amyloid funnel-vision. Check out my full strategic analysis in the graphic below! 🚀 #Alzheimers #Biotech #Investing #Neuroscience #TheNewNarrative https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD016297/full?highlightAbstract=alzheimer%7Calzheimer%27s%7Calzheim

Mizuho🏁 $CLYM Outperform; $18 $RHHBY $BIIB VRTX GSK Mizuho said: We are initiating coverage of Climb Bio with an Outperform rating and $18 price target, as we see its lead assets budoprutug (anti-CD19 mAb) and CLYM116 (anti-APRIL mAb) as positioned to establish a compelling B-cell targeting pipeline with best-in-indication profiles in autoimmune nephropathies. Specifically, we believe additional updates for budoprutug in primary membranous nephropathy (pMN) in 2H26 and initial data for CLYM116 in healthy volunteers (HVs) in mid-2026 have the opportunity to provide data points that will validate potential to drive the deepest reductions in proteinuria within their competitive landscapes. As we exit 2026, budoprutug and CLYM116 could be positioned for registrational development across two blockbuster opportunities that we believe could support ~$600M in risk-adjusted WW sales by 2035.
