Alector (ALEC) Stock Price, News & Analysis

Company Overview

Alector is a clinical-stage biotechnology company headquartered in South San Francisco, California. Founded in 2013, the company is focused on discovering and developing immuno-neurology therapies that target the innate immune system to treat a range of neurodegenerative disorders. Alector’s approach aims to harness the body’s natural defense mechanisms to clear pathological proteins and restore neuronal function in conditions such as Alzheimer’s disease and frontotemporal dementia.

The company’s pipeline includes multiple product candidates in both preclinical and clinical stages, with lead programs AL001 and AL002 advancing in frontotemporal dementia and Alzheimer’s disease studies. Alector designs its molecules to engage key immune receptors in the brain, seeking to slow or halt disease progression rather than simply address symptoms. Research and development activities are supported by state-of-the-art laboratories in North America and collaborations with academic and industry partners in Europe.

Since completing its initial public offering in 2019, Alector has expanded its clinical footprint through strategic alliances and investigator-initiated trials. The company maintains global development programs aimed at bringing the first approved immuno-neurology therapies to patients worldwide.

Alector is led by co-founder and Chief Executive Officer Dr. Arnon Rosenthal, a neuroscientist with over two decades of experience in immunology and drug discovery. The management team brings extensive backgrounds in clinical development, regulatory affairs, and commercialization, supporting Alector’s mission to transform the treatment landscape for neurodegenerative diseases.
