• Topline results for ACU193, the first clinical stage amyloid beta oligomer (AβO)-directed antibody, to provide deeper insight into candidate’s therapeutic potential for the treatment of early Alzheimer’s disease
• Phase 1 INTERCEPT-AD data investigating safety, pharmacokinetics and target engagement of ACU193 to be included in a Featured Research Session as a Developing Topics oral presentation on July 16
  
• Company to host conference call and webcast for investors and analysts July 17 at 8 a.m. ET
  

CHARLOTTESVILLE, Va. and CARMEL, Ind., June 13, 2023 (GLOBE NEWSWIRE) -- Acumen Pharmaceuticals, Inc. (NASDAQ: ABOS), a clinical-stage biopharmaceutical company developing a novel therapeutic that targets soluble amyloid beta oligomers (AβOs) for the treatment of Alzheimer’s disease (AD), today announced that it will present topline results from a Phase 1 trial of its candidate ACU193, the first clinical stage AβO-directed antibody therapy, at the Alzheimer’s Association International Conference (AAIC®) 2023 taking place in Amsterdam, Netherlands and online from July 16-20, 2023. As part of a Featured Research Session - Developing Topics platform, four presentations will be made that discuss the Phase 1 trial.

Decades of research have shown that soluble AβOs are a distinctly toxic form of Aβ, based on their propensity to bind to neurons, disrupt synapses and contribute to tau hyper-phosphorylation. ACU193 is a humanized monoclonal antibody that selectively targets toxic soluble AβOs and may prevent AβOs from binding to synapses and disrupting neuronal function.

“We are excited to present the first clinical data from our Phase 1 INTERCEPT-AD trial to the scientific and medical community at AAIC, including evidence of the overall safety profile, pharmacokinetic data, and target engagement of ACU193,” said Daniel O’Connell, President and Chief Executive Officer of Acumen. “This will also mark the first clinical proof-of-mechanism data in the field from a monoclonal antibody with high selectivity for toxic amyloid beta oligomers, highlighting the potential of a differentiated antibody product that targets early and persistent triggers of Alzheimer’s pathology. We believe the INTERCEPT-AD trial is an important step to developing a next generation treatment with a compelling benefit-risk balance for patients with early Alzheimer’s disease.”

Topline INTERCEPT-AD data will be presented in a Featured Research Session as part of the Developing Topics program on Sunday, July 16, 2023 from 8 a.m. – 8:45 a.m. CEST (2 a.m. – 2:45 a.m. ET). The session will be co-chaired by Dr. Eric Siemers, Acumen’s Chief Medical Officer, and Dr. Kimball Johnson, Medical Director of iResearch Atlanta and iResearch Savannah and an INTERCEPT-AD trial investigator.

The session will include the following presentations:

Abstract: #82615
Title: Baseline characteristics of INTERCEPT-AD: A phase 1 trial with ACU193 targeting soluble amyloid beta oligomers for the treatment of early Alzheimer’s disease

Abstract: #82860
Title: Recruitment strategies and tactics for INTERCEPT-AD: A phase I trial of Aβ oligomer-targeting ACU193 in early Alzheimer’s disease

About ACU193

ACU193 is a humanized 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 a growing body of evidence indicating that soluble AβOs are a primary underlying cause of the neurodegenerative process in Alzheimer’s disease. ACU193 has been granted Fast Track designation for the treatment of early Alzheimer’s disease by the U.S. Food and Drug Administration.  

About INTERCEPT-AD

INTERCEPT-AD is a Phase 1, U.S.-based, multi-center, randomized, double-blind, placebo-controlled clinical trial evaluating the safety and tolerability, and establishing clinical proof of mechanism, of ACU193 in patients with early Alzheimer’s disease (AD). Sixty-five individuals with early AD (mild cognitive impairment or mild dementia due to AD) enrolled in this first-in-human study of ACU193. The INTERCEPT-AD study 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 has completed enrollment. More information can be found on www.clinicaltrials.gov, NCT identifier NCT04931459.
