Michael Riad's questions to Alector (ALEC) leadership • Q2 2025
Question
Michael Riad of Morgan Stanley asked Dr. Darby if a successful outcome in FTD-GRN would increase confidence in using a progranulin-elevating approach for Alzheimer's disease. He also asked how the INFRONT3 analysis normalizes for inter-patient variability in baseline progranulin levels.
Answer
Dr. Ryan Darby stated that success would support the mechanism and open possibilities for other indications. CMO Giacomo Salvadore explained the analysis compares the active arm to placebo and that FTD-GRN mutations consistently cause a ~50% reduction in progranulin. CEO Arnon Rosenthal further clarified the specific genetic nature of FTD-GRN mutations.
