Alector Enters Global License Agreement with Genentech for Brain Penetrant GCase Enzyme Replacement Therapy for Parkinson’s Disease and Other Neurodegenerative Diseases
Alector (ALEC) licensed AL050, a GCase ERT for Parkinson’s and neurodegenerative diseases, to Genentech. Alector receives $100M upfront, up to $1.17B in milestones, and royalties. AL050 uses Alector’s ABC tech to cross the blood-brain barrier. Genentech handles development, while Alector retains ABC rights. Alector will use funds to advance its pipeline, including Alzheimer’s and Parkinson’s programs. A webinar on Oct 13 will discuss Alector’s wholly owned pipeline.
