Alector, Inc. is a clinical-stage biotechnology company at the forefront of the immuno-neurology field, developing innovative therapies to treat devastating neurodegenerative disorders. The company's unique approach focuses on harnessing the power of the immune system to protect and restore brain health, offering a promising path forward in an area that has historically been plagued by limited treatment options.
Business Overview and Company History
Alector was founded in 2013 by renowned neuroscientist Dr. Arnon Rosenthal, who recognized the untapped potential of the immune system's role in neurodegeneration. The company's early work centered on identifying genetic targets associated with neurodegenerative diseases and developing monoclonal antibodies and small molecules to modulate those targets.
Since its inception, Alector has primarily financed its operations through the sale of equity securities and upfront payments received from collaboration arrangements. In October 2017, the company entered into a significant agreement with AbbVie to co-develop and commercialize medicines for Alzheimer's disease and other neurodegenerative diseases, receiving $205 million in upfront payments.
One of Alector's key innovations is its focus on progranulin (PGRN), a protein that plays a critical regulatory role in the immune system and neuronal function. The company's lead candidate, latozinemab, is a monoclonal antibody designed to elevate PGRN levels and has shown promise in treating frontotemporal dementia (FTD) with progranulin gene mutations (FTD-GRN), a rare and devastating neurodegenerative disorder.
In July 2021, Alector entered into a collaboration agreement with global pharmaceutical giant GlaxoSmithKline (GSK) to jointly develop and commercialize latozinemab and another PGRN-targeting candidate, AL101, for neurodegenerative diseases. This partnership provided Alector with $700 million in upfront payments, significantly bolstering its financial resources and expertise to advance its PGRN portfolio.
Alector's pipeline also includes AL002, a first-in-class TREM2 agonist antibody, which is currently in a Phase 2 clinical trial for the treatment of early Alzheimer's disease. TREM2 is a key regulator of microglial function, and modulating this pathway has the potential to restore the brain's protective mechanisms against neurodegeneration.
Despite its progress, Alector has faced challenges in its drug development efforts. In 2022, AbbVie decided to terminate the CD33 collaboration program, concluding that further development of AL003 was not warranted. Additionally, Alector closed the Phase 1 clinical trial for its AL044 product candidate based on initial pharmacokinetic and tolerability data. However, the company has persevered, with three product candidates currently in clinical development - latozinemab, AL002, and AL101.
Financial Overview and Liquidity
As of September 30, 2024, Alector reported a strong cash, cash equivalents, and investments position of $457.2 million, providing the company with a cash runway through 2026. This robust financial foundation should enable Alector to continue advancing its pipeline and navigate the capital-intensive nature of drug development.
For the nine months ended September 30, 2024, Alector reported total revenue of $46.32 million, primarily derived from its collaborations with GSK and AbbVie. The company's net loss for the period was $116.97 million, in line with its ongoing investment in research and development activities.
Alector's balance sheet remains healthy, with a current ratio of 3.29 and a quick ratio of 3.29 as of September 30, 2024, indicating strong liquidity and the ability to meet short-term obligations. The company's debt-to-equity ratio remains at 0, further strengthening its financial position.
For the fiscal year 2023, Alector reported revenue of $97.06 million, with a net loss of $130.39 million. The company's operating cash flow (OCF) was negative $184.16 million, and free cash flow (FCF) was negative $186.54 million.
In the most recent quarter (Q3 2024), Alector's revenue was $15.34 million, representing a 76.9% decrease year-over-year, primarily due to a decrease in collaboration revenue recognized under the GSK and AbbVie agreements. The net loss for the quarter was $42.22 million, with an operating cash flow of negative $50.73 million and free cash flow of negative $50.95 million.
Alector has provided financial guidance for 2024, expecting collaboration revenue to be between $60 million and $70 million. The company has tightened its total research and development guidance to be between $210 million and $220 million, while reiterating its total general and administrative guidance to be between $60 million and $70 million.
In November 2024, Alector secured a $50 million credit facility from Hercules Capital, further bolstering its financial resources.
Pipeline Progress and Upcoming Catalysts
Alector's pipeline is anchored by two lead programs, latozinemab and AL002, both of which have reached important milestones in their clinical development.
Latozinemab, the company's PGRN-targeting antibody, is currently in a pivotal Phase 3 trial (INFRONT-3) for the treatment of FTD-GRN. In February 2024, the U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy Designation to latozinemab for this indication, underscoring the significant unmet need and the potential of this investigational therapy. Latozinemab has also previously received orphan drug designation from the FDA for the treatment of FTD.
Notably, Alector recently reported baseline characteristics for the INFRONT-3 trial, which suggest a representative study population for testing the effects of latozinemab in FTD-GRN. The company expects to report topline data from this pivotal study in late 2025 or early 2026.
Alector's second lead candidate, AL002, is a TREM2 agonist antibody being evaluated in the INVOKE-2 Phase 2 clinical trial for the treatment of early Alzheimer's disease. The company has provided updates on the trial's design, including the use of a novel proportional MMRM statistical analysis approach to maximize the potential to detect treatment effects. Alector anticipates reporting data from the INVOKE-2 trial in the fourth quarter of 2024.
The company's third clinical-stage candidate, AL101, is designed to elevate progranulin levels, similar to latozinemab. AL101 is currently being investigated for the potential treatment of Alzheimer's disease and potentially other indications, including Parkinson's disease. In May 2023, Alector and GSK amended their collaboration agreement, with Alector now responsible for funding and sharing in the development costs up to $140.5 million for the conduct of the initial Phase 2 trial of AL101 in Alzheimer's disease. The Phase 2 PROGRESS-AD trial for AL101 in early Alzheimer's disease is ongoing, with dosing initiated in early 2024.
In addition to its late-stage programs, Alector is also advancing its proprietary Alector Brain Carrier (ABC) technology, a versatile platform designed to enhance the delivery of therapeutic agents to the central nervous system. The introduction of ABC represents a significant step forward in Alector's capabilities to address the challenge of effective drug delivery in neurodegenerative diseases.
