Introduction to Alector Inc.

Alector Inc. is a clinical-stage biotechnology company headquartered in South San Francisco, California, dedicated to pioneering the field of immuno-neurology. Founded in 2013 by renowned neuroscientists and immunologists, Alector has rapidly emerged as a leader in understanding the role of the immune system in neurodegenerative diseases. The company’s core focus lies in developing therapies that harness the brain’s innate immune system to combat diseases such as Alzheimer’s, Frontotemporal Dementia (FTD), Amyotrophic Lateral Sclerosis (ALS), and Parkinson’s disease. With a market capitalization exceeding $1.5 billion and strategic partnerships with industry giants like GlaxoSmithKline (GSK) and AbbVie, Alector has established a strong reputation for scientific innovation and clinical execution. The company’s pipeline includes several first-in-class monoclonal antibodies targeting key immune checkpoints in microglia, the brain’s resident immune cells. Alector’s unique approach has been validated by positive Phase 2 data for its lead candidate, AL001 (latozinemab), in FTD. With over 200 employees, a state-of-the-art research facility, and a robust portfolio of intellectual property, Alector is recognized as a top employer in the biotechnology sector, consistently ranked among the best places to work in the Bay Area. The company’s commitment to transparency, scientific rigor, and patient-centricity makes it a trusted partner for academic institutions, patient advocacy groups, and regulatory agencies worldwide.

Company History and Business Evolution

Alector Inc. was founded in 2013 by Dr. Asa Abeliovich, Dr. Arnon Rosenthal, and Dr. Joachim Herz, three distinguished scientists with deep expertise in neuroscience and immunology. The company’s inception was driven by a groundbreaking hypothesis: that the immune system plays a central role in neurodegenerative diseases, and that targeting immune checkpoints in the brain could halt or reverse disease progression. In its early years, Alector operated in stealth mode, focusing on building a proprietary platform to identify and validate novel targets in microglia. The company secured significant venture capital funding from top-tier investors including OrbiMed, Polaris Partners, and ARCH Venture Partners. By 2016, Alector had raised over $100 million to advance its pipeline. A major milestone came in 2017 when the company initiated its first Phase 1 clinical trial for AL001, a monoclonal antibody targeting the TREM2 receptor, a key regulator of microglial function. In 2019, Alector went public on the Nasdaq under the ticker symbol ALEC, raising $220 million in its IPO. The same year, the company announced a landmark partnership with GSK to develop up to 15 novel immuno-neurology programs, securing $700 million in upfront and milestone payments. This partnership validated Alector’s platform and provided the resources to accelerate clinical development. In 2021, Alector reported positive Phase 2 data for AL001 in patients with FTD caused by a specific genetic mutation, showing a significant reduction in disease progression. This data was published in the New England Journal of Medicine. The company has since expanded its pipeline to include AL002 (targeting TREM2) and AL003 (targeting SIGLEC-3), both in Phase 2 for Alzheimer’s disease. Alector has also partnered with AbbVie on AL004, a next-generation TREM2 agonist, and with Visterra on AL008, a dual-targeting antibody. In 2023, Alector opened a new research facility in South San Francisco, doubling its laboratory capacity. The company continues to evolve, exploring new indications such as chronic pain and multiple sclerosis, and investing in gene therapy and cell therapy approaches. Today, Alector is recognized as a pioneer in immuno-neurology, with a rich history of scientific discovery, strategic collaborations, and clinical progress.
