#ALEC — Alector Advances Brain-Delivery Pipeline With Genentech Deal | ThinkSabio
Oct 26, 2026 · ThinkSabio Inc
Alector is developing next-generation therapies for neurodegenerative diseases through its proprietary Alector Brain Carrier (ABC) platform, designed to improve drug delivery across the blood–brain barrier.
🔹 Key Highlights
🧠 ABC Platform: Alector's technology is designed to improve delivery of therapies into the brain.
💊 AL137: Brain-enabled anti-amyloid beta antibody targeting Alzheimer's disease.
🧬 AL164: Tau-targeting siRNA being developed for Alzheimer's and other tauopathies.
🤝 Genentech Partnership: Genentech, part of Roche, licensed AL050, including $100M upfront, up to $1.17B in additional milestones, plus royalties.
💰 Capital Position: Alector raised $75M gross through a common-stock offering and had $172.8M in cash and investments as of June 30, 2026.
⚠️ Clinical Risk: The Phase 2 AL101 Alzheimer's trial was discontinued following an interim futility analysis.
🚀 Upcoming Catalysts: AL137 IND submission is targeted for Q1 2027, with first-in-human dosing targeted by April 2027.
📅 Runway: Management said the Genentech deal extends the company's runway into 2029.
💡 Why It Matters
The Genentech partnership provides external validation for Alector's brain-delivery technology while bringing upfront capital and potential milestone payments. The major opportunity now centers on advancing AL137 and the broader ABC platform toward clinical testing, although early-stage development and dilution remain important risks.
