Alector Initiates Phase 1 Clinical Trial of AL044 for the Treatment of Alzheimer’s Disease (AD)
AL044 is the first clinical-stage drug candidate targeting MS4A, a major genetic risk factor for AD
AL044, a novel first-in-class therapeutic candidate, seeks to counteract multiple AD pathologies through modulating microglia, the brain’s immune cells
Company has three novel immuno-neurology drug candidates in development to potentially address the significant unmet need in AD
AL044 is a function-modulating biologic targeting MS4A, a brain immune checkpoint molecule and a genetic risk factor for Alzheimer's diseases (AD). MS4A is a unique risk gene for late-onset sporadic AD that appears to regulate, either directly or through TREM2, multiple aspects of disease risk and progression including the rate of Abeta and Tau accumulation, the rate of cognitive decline, the rate of brain tissue loss, the rate of conversion from mild cognitive impairment to AD and the age of onset and survival with AD. In preclinical studies, AL044 was shown in vivo to control microglial key signaling systems that drive proliferation, survival, lysosomal activity, migration, phagocytosis, energetics, and immune response. AL044 is anticipated to recruit microglia to counteract multiple AD disease pathologies either as a stand-alone therapy or in combination with therapies against misfolded proteins. By recruiting the brain’s immune system to counteract disease pathologies, AL044 represents a paradigm shift in therapies for neurodegeneration akin to immuno-oncology.
“The initiation of this Phase 1 trial of AL044 further demonstrates Alector’s leadership and pioneering approach to activate the brain’s immune system as a novel way to potentially slow and repair neurodegeneration,” said
Approximately 72 healthy participants will be enrolled in the Phase 1 trial of AL044.
AD afflicts more than six million Americans and places a substantial burden on families, caregivers and the healthcare system. Alector currently has three novel immuno-neurology drug candidates in development to potentially address the significant unmet need in AD. AL101 is a human recombinant monoclonal antibody that targets SORT1 and is designed to elevate progranulin levels and is being developed to target chronic neurodegenerative diseases such as AD and Parkinson’s Disease in collaboration with GSK. AL002 is a TREM2 activating monoclonal antibody being developed in collaboration with AbbVie to increase TREM2 signaling and the functionality of microglia brain specific immune cells for the treatment of AD. AL044 is a function-modulating biologic that has now begun clinical development as a potential new treatment option for AD and possibly orphan neurodegenerative diseases.
