Alector licenses AL050 to Genentech for $100M upfront and up to $1.17B in milestones

Alector granted Genentech exclusive worldwide rights to develop and commercialize its AL050 engineered GCase program. The agreement provides Alector with a $100 million upfront payment and potential milestone payments of up to $1.17 billion, plus tiered royalties. A separate non‑exclusive license was secured from Spur Therapeutics for $15 million and a revenue‑share on sublicense income. The deals monetize the AL050 asset and secure needed IP support.

The upfront cash and future milestone potential improve Alector’s balance sheet and give investors a near‑term liquidity boost, while the partnership may accelerate AL050’s development. The company’s filing states the transactions are intended to monetize a non‑core asset and advance the program.
