Acumen Pharmaceuticals to Present Studies on Cost Savings Associated with Use of pTau217 Screening Assay in Phase 2 ALTITUDE-AD Study and Sabirnetug Oligomer-Selectivity at the Alzheimer’s Association International Conference (AAIC®) 2025

NEWTON, Mass., July 10, 2025 (GLOBE NEWSWIRE) --  (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), will present new findings at the upcoming Alzheimer's Association International Conference (AAIC®) 2025 in Toronto. The presentations include a cost savings analysis of the use of pTau217 as a screening tool in Acumen’s Phase 2 ALTITUDE-AD trial of sabirnetug as well as a nonclinical study evaluating the relative selectivity of sabirnetug to targeting AβOs versus Aβ monomers. The conference will be held July 27-31, 2025, both in-person and online.

Acumen’s presentation details are as follows:

“Our presentation at AAIC highlight how combining biomarker-driven screening with a targeted therapeutic like sabirnetug represents meaningful progress in trial designs and drug development for Alzheimer’s disease,” said Eric Siemers, M.D., Chief Medical Officer of Acumen Pharmaceuticals. “We look forward to sharing these findings at AAIC, which reinforce both sabirnetug's distinct selectivity for toxic amyloid beta oligomers as well as our approach to making clinical trials more patient-centric and efficient.”

About Sabirnetug (ACU193)

Sabirnetug (ACU193) is a humanized monoclonal antibody (mAb) discovered and developed based on its selectivity for soluble amyloid beta oligomers (AβOs), which are a highly 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, sabirnetug aims to address the hypothesis that soluble AβOs are an early and persistent underlying cause of the neurodegenerative process in Alzheimer’s disease (AD). Sabirnetug has been granted Fast Track designation for the treatment of early AD by the U.S. Food and Drug Administration and is currently being evaluated in a Phase 2 study in patients with early AD.

About ALTITUDE-AD (Phase 2)

Initiated in 2024, ALTITUDE-AD is a Phase 2, multi-center, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the efficacy and safety of sabirnetug (ACU193) infusions administered once every four weeks in slowing cognitive and functional decline as compared to placebo in participants with early Alzheimer's disease. The study has enrolled 542 individuals with early Alzheimer’s disease (mild cognitive impairment or mild dementia due to AD) at multiple investigative sites located in the United States, Canada, the European Union and the United Kingdom. More information can be found on , NCT identifier NCT06335173.

About Acumen Pharmaceuticals, Inc.

Acumen Pharmaceuticals is a clinical-stage biopharmaceutical company developing a novel therapeutic that targets toxic soluble amyloid beta oligomers (AβOs) for the treatment of Alzheimer’s disease (AD). Acumen’s scientific founders pioneered research on AβOs, which a growing body of evidence indicates are early and persistent triggers of Alzheimer’s disease pathology. Acumen is currently focused on advancing its investigational product candidate, sabirnetug (ACU193), a humanized monoclonal antibody that selectively targets toxic soluble AβOs, in its ongoing Phase 2 clinical trial ALTITUDE-AD (NCT06335173) in early symptomatic Alzheimer’s disease patients, following positive results in its Phase 1 trial INTERCEPT-AD. The company is headquartered in Newton, Mass. For more information, visit .
