Alector announced two material terminations. GSK delivered notice on Jul. 6, 2026 to end the companies' Collaboration and License Agreement for progranulin-elevating antibodies, with termination effective Jan. 2, 2027, following setbacks in Phase 3 and Phase 2 studies. Separately, on Jul. 8, 2026, Alector repaid $10,428,827.77 of principal and terminated its Loan and Security Agreement with lenders led by Hercules Capital, also covering accrued interest and applicable end-of-term and prepayment charges.
