Company and pipeline overview
Focus on neurodegenerative diseases with five drugs advanced to the clinic, including a Progranulin-elevating drug for Alzheimer's in partnership with GSK, with phase II interim analysis expected in the first half of next year.
Multiple preclinical programs leverage proprietary Blood-Brain Barrier (BBB) technology to enhance brain delivery of large molecules.
Pipeline includes anti-amyloid-β antibody, GCase enzyme replacement therapy for Parkinson's and Lewy body dementia, and a portfolio of BBB-enabled siRNA programs targeting Tau, α-synuclein, and NLRP3.
Blood-Brain Barrier technology and ABC platform
BBB technology enables 10-50x higher brain concentrations of drugs, allowing lower peripheral doses and improved safety.
Uses transferrin receptor as a transport mechanism, with unique epitope and affinity optimizations to maximize brain delivery and minimize anemia risk.
Platform is highly adaptable, allowing for different drug modalities and configurations tailored to each therapeutic target.
Drug configuration, transferrin affinity, and epitope selection are optimized for each modality to balance efficacy, safety, and pharmacokinetics.
Anti-amyloid-β antibody (AL137) program
AL137 and its backup show 4-12x higher brain penetration than competitors, aiming for subcutaneous delivery and lower dose to reduce safety risks.
Phase I studies will use amyloid PET imaging and ARIA monitoring in small cohorts to assess amyloid clearance and safety early.
Targeting a clinic entry in 2026, with rapid assessment of efficacy and safety endpoints.
ABC platform: anemia mitigation strategy
AL101: Universal neurodegeneration risk gene impact
AL50: Strategy for sporadic Parkinson's patients

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
