Business Overview
Harnessing the Power of Immune Dysfunction to Combat Neurodegeneration
Alector's core focus is on developing therapies that target immune dysfunction as a root cause of neurodegenerative diseases. The company's immuno-neurology approach aims to functionally repair genetic mutations that cause dysfunction in the brain's immune system, enabling rejuvenated immune cells to counteract emerging brain pathologies.
The company's lead product candidates, latozinemab (AL001) and AL002, are in advanced stages of clinical development. Latozinemab, a progranulin-elevating monoclonal antibody, is being evaluated in the pivotal Phase 3 INFRONT-3 trial for the treatment of frontotemporal dementia (FTD) with progranulin gene mutations (FTD-GRN). In October 2023, Alector achieved target enrollment of 103 symptomatic and 16 at-risk participants in this study, which is being conducted in collaboration with partner GSK.
AL002, a TREM2-targeting monoclonal antibody, is currently in the Phase 2 INVOKE-2 trial for the treatment of early Alzheimer's disease. The study, which completed enrollment of 381 participants in 2023, is designed to assess the safety and efficacy of AL002 in slowing disease progression. Alector and partner AbbVie are eagerly anticipating the topline data from this trial, expected in the fourth quarter of 2024.
In addition to these lead programs, Alector is also advancing AL101, a second progranulin-elevating candidate, in collaboration with GSK. The PROGRESS-AD Phase 2 trial of AL101 in early Alzheimer's disease dosed its first participant in February 2024, further expanding Alector's footprint in this critical therapeutic area.
Innovative Research and Development: Alector Brain Carrier Technology
Alector's research and development efforts are not limited to its clinical-stage programs. The company has also made significant strides in developing its proprietary Alector Brain Carrier (ABC) technology, a versatile platform designed to enhance the delivery of therapeutics to the central nervous system.
The ABC technology employs a suite of single-chain variable fragments, antigen-binding fragments, and variable heavy chain domains that target blood-brain barrier proteins, such as transferrin receptor (TFR) and CD98 heavy chain. This approach has demonstrated the ability to achieve more than a tenfold increase in brain concentrations of various cargoes, enabling improved delivery and potentially lower efficacious doses with favorable safety and efficacy profiles.
Alector plans to selectively deploy the ABC technology across its next-generation programs, further strengthening its position as a leader in immuno-neurology. The modular and customizable nature of the ABC platform allows the company to tailor the therapeutic's affinity, valency, and format to the specific mechanism of action and cell type targeting requirements of each program.
Financial Highlights and Outlook
Alector's financial performance in the fourth quarter of 2023 was marked by collaboration revenue of $15.2 million, compared to $14.4 million in the same period of 2022. For the full year 2023, the company reported collaboration revenue of $97.1 million, down from $133.6 million in 2022.
Total research and development expenses for the fourth quarter were $47.7 million, compared to $54.5 million in the same period of 2022. For the full year 2023, total research and development expenses were $192.1 million, down from $210.4 million in 2022. General and administrative expenses for the fourth quarter were $14.9 million, compared to $15.4 million in the same period of 2022. For the full year 2023, total general and administrative expenses were $56.7 million, down from $61.0 million in 2022.
Looking ahead, Alector provided guidance for 2024, estimating collaboration revenue to be between $60 million and $70 million. The company anticipates total research and development expenses to be between $210 million and $230 million, and total general and administrative expenses to be between $60 million and $70 million.
Alector's strong cash position, bolstered by the recent $75 million follow-on financing, provides the company with a cash runway through 2026, well beyond the expected data readouts for its lead programs. This financial flexibility allows Alector to continue advancing its clinical pipeline, investing in its innovative ABC technology, and exploring new opportunities to drive long-term growth.
Regulatory Milestones and Collaborations
Alector has achieved several important regulatory milestones in 2023 and early 2024. In February 2024, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation to latozinemab for the treatment of FTD-GRN, a significant recognition of the drug's potential to address this devastating condition.
The company's collaborations with industry leaders, such as GSK and AbbVie, have been instrumental in advancing its pipeline. The GSK Agreement, signed in 2021, covers the global development and commercialization of Alector's progranulin-elevating monoclonal antibodies, including latozinemab and AL101.
