Acumen Pharmaceuticals to Present Clinical Trial Design for INTERCEPT-AD, the Phase 1 Placebo-Controlled, Single- and Multiple-Dose Clinical Trial of ACU193, at 2021 Clinical Trials on Alzheimer’s Disease (CTAD) Conference

ACU193 is the first monoclonal antibody to enter a clinical trial that was discovered and is being developed to selectively target toxic amyloid-beta oligomers (AβOs)

Acumen announced dosing of first patient in INTERCEPT-AD in October 2021 and enrollment of patients with early Alzheimer’s disease is ongoing

CHARLOTTESVILLE, Va. and CARMEL, Ind., Nov. 02, 2021 (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 the company will deliver an oral presentation on the clinical trial framework of its product candidate, ACU193, at the 2021 Clinical Trials on Alzheimer’s Disease (CTAD) conference, being held in-person and virtually November 9-12 in Boston. ACU193 is a monoclonal antibody that selectively targets toxic soluble amyloid-beta oligomers (AβOs) for the treatment of early Alzheimer’s disease.

Toxic soluble 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 believe research over more than two decades has pointed toward toxic soluble Aβ oligomers as a promising therapeutic target for Alzheimer’s disease,” said Eric Siemers, M.D., Chief Medical Officer at Acumen. “ACU193 is differentiated in its selective targeting of Aβ oligomers, providing the possibility of short-term improvements in synaptic function in addition to potential long-term disease modification with slowing of the Alzheimer’s disease process. We believe that oligomer-specific therapeutics are less likely to result in amyloid-related imaging abnormalities – or ARIA – a major safety concern for plaque-targeting drugs.”

Dr. Siemers’ presentation at CTAD will discuss the scientific rationale for targeting AβOs, the clinical trial design of the Phase 1 INTERCEPT-AD study of ACU193, and how the study is designed to measure potential improvements in cognition and blood flow in the brain.

Details of the oral presentation:

  • Presentation number: OC3
  • Presentation Title: Phase 1 trial design for ACU193, a monoclonal antibody that selectively binds soluble Aβ oligomers
  • Presenter: Eric Siemers, M.D., Chief Medical Officer, Acumen Pharmaceuticals
  • Date & Time: Wednesday, Nov. 10, 2021; 9:20 a.m. ET
  • Location: Boston Park Plaza, Grand Ballroom A

The presentation will be streamed live on the CTAD digital platform and a recorded version of the presentation will be available within 48 hours after the event on the CTAD website for those registered for the meeting.

About ACU193
ACU193 is a monoclonal antibody (mAb) discovered and developed based on its selectivity for soluble AβOs, which Acumen believes are the most toxic and pathogenic form of Aβ relative to Aβ monomers and amyloid plaques. Soluble AβOs have been observed to be potent neurotoxins that bind to neurons, inhibit synaptic function and induce neurodegeneration. By selectively targeting toxic soluble AβOs, ACU193 aims to directly address what a growing body of evidence indicates is a primary underlying cause of the neurodegenerative process in AD.

Approximately 62 individuals with early AD (mild cognitive impairment or mild dementia due to AD) are expected to be randomized into this double-blind, placebo-controlled, first-in-human study of ACU193. INTERCEPT-AD is designed to establish safety and proof of mechanism. It consists of single-ascending-dose (SAD) and multiple-ascending-dose (MAD) cohorts and is designed to evaluate the safety, tolerability, pharmacokinetics (PK), and target engagement of intravenous doses of ACU193. The study is enrolling at multiple investigative sites located in the United States. More information can be found on, NCT identifier NCT04931459.

About Acumen Pharmaceuticals, Inc.
Acumen Pharmaceuticals, headquartered in Charlottesville, Va. with clinical operations based in Carmel, Ind., is a clinical stage biopharmaceutical company developing a novel disease-modifying approach to treat Alzheimer’s disease. Acumen’s scientific founders pioneered research on toxic soluble AβOs, which a growing body of evidence indicates are primary triggers of Alzheimer’s disease pathology. Acumen is currently focused on advancing its investigational product candidate, ACU193, a humanized monoclonal antibody that selectively targets toxic soluble AβOs in a Phase 1 clinical trial involving early Alzheimer’s disease patients.
