About Acumen Pharmaceuticals

Biological Products, (No Diagnostic Substances), SIC 2836

Acumen Pharmaceuticals is a clinical-stage biopharmaceutical company focused on developing targeted disease-modifying therapies for Alzheimer’s disease. Its lead product candidate, sabirnetug (ACU193), is a recombinant humanized monoclonal antibody designed to selectively bind and neutralize soluble amyloid-beta oligomers, which are neurotoxic assemblies implicated in synaptic dysfunction and neurodegeneration. In addition to sabirnetug, the company is advancing blood-brain barrier-penetrating enhanced brain delivery therapies for Alzheimer’s pathology. As a clinical-stage enterprise, its candidates target individuals diagnosed with early Alzheimer’s disease, encompassing those with mild cognitive impairment or mild dementia associated with amyloid pathology.

The company operates without internal commercial manufacturing, storage, or distribution facilities, relying instead on specialized contract manufacturers to supply drug substances, drug products, and raw materials for clinical programs. The provided text discusses clinical operations within the United States but does not state the company's headquarters location or full operational scale.
