Comprehensive Analysis in Frontiers in Neuroscience Highlights Acumen Pharmaceuticals’ New Approach to Treating Alzheimer's Disease

CHARLOTTESVILLE, Va. and CARMEL, Ind., April 27, 2022 (GLOBE NEWSWIRE) -- Acumen Pharmaceuticals, Inc. (NASDAQ: ABOS), a clinical stage biopharmaceutical company focused on the development of novel targeted therapeutics for Alzheimer’s disease (AD), today announced that Frontiers in Neuroscience published a summary of preclinical evidence supporting ACU193, a monoclonal antibody that selectively targets toxic soluble Aβ oligomers (AβOs) for the potential treatment of early Alzheimer’s disease. The article is titled “ACU193: An immunotherapeutic poised to test the amyloid β oligomer hypothesis of Alzheimer’s disease” and can be accessed here.
Studies suggest that AβO-mediated neuronal toxicity is directly responsible for Alzheimer’s-associated memory and cognitive problems. AβOs have been found to interact within synapses of brain cells called neurons, which leads to altered neuronal function, and may initiate and perpetuate the process of neurodegeneration, ultimately leading to cell death.
“We are increasingly learning more about the specific roles certain entities in the amyloid cascade, like AβOs, play in Alzheimer’s disease pathology,” said Eric Siemers, M.D., Chief Medical Officer at Acumen Pharmaceuticals and co-author of the publication. “We believe targeting AβOs remains a promising approach because evidence suggests they are the most toxic form of Aβ and may be responsible for the memory impairment and cognitive decline in Alzheimer’s patients. We expect our ongoing Phase I clinical trial of ACU193 to provide further explanatory information and proof of mechanism data that will potentially pave the way towards testing of this hypothesis in larger studies. We look forward to sharing the results from our Phase I clinical trial once available.”
Acumen believes ACU193 has many essential properties needed for a successful therapeutic and selectively binds to AβOs. Preclinical data highlights in the publication on ACU193 include:
- ACU193 selectively binds AβOs with 650-fold selectivity compared to Aβ monomers with limited to no binding to fibrillar Aβ in vitro
- ACU193 prevents AβO-induced disruption of long-term potentiation (LTP), a process of strengthening synapses that is important for learning and memory
- ACU193 can bind to a wide range of AβOs with varying molecular weights
- The parent of ACU193, called ACU3B3, prevents AβO-induced disruption of calcium homeostasis, an early sign of cellular dysfunction
- ACU3B3 significantly improved behavioral deficits across various assessments when administered to animal models at an age when AβO levels were measurable but prior to plaque deposition
Current therapeutics targeting amyloid plaque cause amyloid related imaging abnormalities (ARIA), including cerebral edema (ARIA-E) or microhemorrhage (ARIA-H), which may complicate the utility of such medicines. Current preclinical data suggest that ACU193 is not expected to elicit ARIA side effects due to its high selectivity for AβOs and limited binding to plaque.
About Acumen Pharmaceuticals, Inc.
Acumen, headquartered in Charlottesville, VA, with clinical operations based in Carmel, IN, is a clinical stage biopharmaceutical company developing a novel disease-modifying approach to treat Alzheimer’s disease. Acumen’s scientific founders pioneered research on AβOs, which a growing body of evidence indicates are primary triggers of Alzheimer’s disease pathology. Acumen is currently focused on advancing its investigational immunotherapy drug, ACU193, a humanized monoclonal antibody that selectively targets toxic AβOs in INTERCEPT-AD, a Phase I clinical trial involving early Alzheimer’s disease patients.
