(Nasdaq: ALEC), a late-stage clinical biotechnology company focused on developing therapies to counteract the devastating progression of neurodegeneration, today reported fourth quarter and full year 2024 financial results and recent portfolio and business updates. As of December 31, 2024, Alector’s cash, cash equivalents and investments totaled $413.4 million. “Alector is entering a potentially transformative period for the company, as we continue to advance our clinical programs toward key milestones while also driving the development of our wholly owned, early-stage pipeline,” said Arnon Rosenthal, Ph.D., Chief Executive Officer of Alector. “We look forward to reporting topline data from the pivotal INFRONT-3 Phase 3 trial of latozinemab targeting frontotemporal dementia with a granulin gene mutation by the fourth quarter. Additionally, we expect to complete enrollment in the PROGRESS-AD Phase 2 trial of AL101/GSK4527226 in participants with early Alzheimer’s disease by mid-2025. With our broad and diverse portfolio of genetically validated drug candidates for the treatment of neurodegenerative diseases, backed by a strong financial position that will fund operations through 2026, Alector is well-positioned to advance our mission to deliver transformative therapies for patients with neurodegenerative brain disorders.” Sara Kenkare-Mitra, Ph.D., President and Head of Research and Development at Alector, added, “We are making significant progress in advancing Alector’s preclinical and research pipeline. By leveraging our expertise in neuroscience and drug discovery, and selectively applying our proprietary Alector Brain Carrier technology platform, we are able to enhance brain delivery and biodistribution of therapeutic cargo to potentially improve safety and efficacy. We are currently selecting lead candidates for two programs, ADP037-ABC, targeting amyloid beta, and ADP050-ABC, replacing GCase. We aim to advance these programs toward IND-enabling studies later this year, with plans to enter the clinic in 2026.” Recent Clinical Updates Progranulin Programs (latozinemab (AL001) and AL101/GSK4527226) Being Developed in Collaboration with GSK Latozinemab The pivotal, randomized, double-blind, placebo-controlled INFRONT-3 Phase 3 clinical trial of latozinemab targeting frontotemporal dementia with a granulin gene mutation (FTD-GRN) is ongoing. Topline data are anticipated by the fourth quarter of 2025. Latozinemab is a novel investigational human monoclonal antibody (mAb) designed to block and downregulate the sortilin receptor to elevate the level of progranulin (PGRN) in the brain. It has been granted Orphan Drug, Breakthrough Therapy and Fast Track designations, and the company believes it is the most advanced PGRN-elevating candidate in development for this condition. AL101/GSK4527226 PROGRESS-AD, a global, randomized, double-blind, placebo-controlled Phase 2 clinical trial evaluating AL101/GSK4527226 in early Alzheimer’s disease (AD) continues to enroll well, with substantial progress toward its target enrollment of 282 participants. Alector and GSK plan to complete trial enrollment by mid-2025. AL101/GSK4527226 is an investigational human mAb designed to block and downregulate the sortilin receptor to elevate the level of PGRN in the brain in a manner that is similar to investigational latozinemab but with different pharmacokinetic and pharmacodynamic properties, making it suitable for the potential treatment of more prevalent neurodegenerative diseases. Preclinical and Research Pipeline Alector is advancing a preclinical and early research pipeline focused on removing toxic proteins, replacing deficient proteins, and restoring immune and nerve cell function. Leveraging its deep expertise in drug development and proprietary technologies, including protein engineering, antibody discovery, and its Alector Brain Carrier (ABC) platform for blood-brain barrier transport, the company is progressing a curated portfolio of programs targeting genetically validated disease mechanisms. This approach has led to a suite of innovative programs with the potential to make a significant impact on neurodegeneration. ADP037-ABC is a proprietary anti-amyloid beta (Aβ) antibody paired with the company’s ABC for the treatment of AD. It is designed to remove brain Aβ plaques, with the potential to reduce the incidence and/or severity of amyloid-related imaging abnormalities (ARIA) and enable subcutaneous delivery. It targets a validated epitope, specific to brain Aβ plaques, combined with an optimized antibody constant region to enhance phagocytosis of Aβ plaques. By leveraging ABC technology, ADP037-ABC aims to clear Aβ efficiently, thereby reducing plaque accumulation and potentially slowing disease progression while minimizing ARIA. ADP050-ABC is a GCase replacement therapy paired with the company’s proprietary ABC for GBA gene mutation carriers with Parkinson’s disease (PD) and Lewy body dementia. In these patients, mutations in the GBA gene lead to deficient GCase activity. ADP050-ABC uses Alector-engineered GCase, which is proprietary and has been designed to have a longer half-life and to break down glucocerebroside, a lipid that accumulates in neurons and contributes to neurodegeneration. This mechanism aims to reduce cellular dysfunction and slow disease progression. ADP056 is a Reelin modulator designed to block tau pathology and promote synaptic function in AD. Reelin, a large, secreted protein, regulates neuronal function and tau accumulation. Gain-of-function Reelin variants protect against familial AD through a mechanism that appears to uncouple amyloid and tau pathology. ADP056 is designed to mimic these protective effects of the Reelin mutation. ADP063-ABC and ADP064-ABC are therapeutic candidates paired with the company’s proprietary ABC that target tau pathology in AD through distinct approaches. First, ADP063-ABC will focus on combining a proprietary anti-tau antibody directed to a validated tau epitope with ABC and an optimized antibody constant region. It is designed to block the spread of tau aggregates and has the potential for subcutaneous delivery. Second, ADP064-ABC will focus on using an anti-tau siRNA combined with ABC, which aims to prevent the synthesis of the tau mRNA and protein. Both approaches seek to leverage a highly brain-penetrant approach to remove toxic tau and potentially slow cognitive decline in AD. In December 2024, Alector and co-recipient University of Luxembourg were awarded a $1.7 million grant from The Michael J. Fox Foundation for Parkinson’s Research (MJFF) for collaborative research on glycoprotein nonmetastatic melanoma protein B (GPNMB), a PD target. Alector plans to hold an educational webinar in the second quarter of 2025 to present additional preclinical data on the company’s anti-amyloid beta and GCase programs, as well as advancements in ABC. TREM2 Program (AL002) On April 5, 2025, Alector plans to present the results from the INVOKE-2 Phase 2 clinical trial, which evaluated the safety and efficacy of AL002, a TREM2 agonist, in individuals with early AD, during an oral presentation at the AD/PD™ 2025 International Conference on Alzheimer’s and Parkinson’s Diseases, taking place in Vienna, Austria. While the trial did not meet its primary endpoint, Alector remains committed to advancing the understanding of AD pathophysiology and the development of effective therapeutics for the disease.
