Acumen Pharmaceuticals and Unlearn Collaborate to Explore Analyses of Alzheimer's Disease Clinical Programs

SAN FRANCISCO, CA AND NEWTON, MA / ACCESS Newswire / July 9, 2026 / Unlearn, a pioneer of AI-powered solutions for clinical development, today announced a collaboration with Acumen Pharmaceuticals (Acumen), a clinical-stage biopharmaceutical company developing novel therapeutics that target toxic soluble amyloid beta oligomers (AβOs) for the treatment of Alzheimer's disease (AD). The collaboration will utilize Unlearn's AI-generated digital twins of trial participants in two of Acumen's AD clinical trials testing their AβO-specific antibody sabirnetug. Digital twins are comprehensive forecasts of an individual trial participant's clinical outcomes at all future timepoints across a given study, used to augment insights from existing trial data and strengthen clearer data-driven decision-making throughout clinical development."Alzheimer's is a highly challenging disease in drug development, and the teams working on it deserve better analytical tools," said Steve Herne, CEO of Unlearn. "We look forward to working with the Acumen team to apply our tools and expertise across the company's clinical portfolio. Alzheimer's disease is an area where we see a strong fit for digital twins to potentially expedite development of new therapies."Unlearn's trial participant digital twins are generated by an AD-specific Digital Twin Generator, trained on more than 26,000 patient records from historical clinical data. Integrated into trial analyses using Unlearn's EMA-qualified and FDA-supported method, this individualized approach may provide a more precise comparator for evaluating treatment effects."We are excited to work with the Unlearn team to apply its digital twin technology to generate deeper insights from our clinical studies," said Jim Doherty, President and Chief Development Officer of Acumen. "As we advance sabirnetug through clinical development, maximizing insights from every study is critical. This collaboration with Unlearn aligns with our commitment to leveraging innovative, scientifically rigorous tools that can strengthen evidence as we work toward potential Phase 3 planning."About UnlearnUnlearn exists to transform clinical development by making every trial smarter. Partnering with pharmaceutical and biotechnology companies, Unlearn harnesses data, AI, and digital twins to enable faster, more robust studies and clearer decision-making across clinical development. With a science-first approach and deep regulatory engagement, including EMA qualification and FDA support, Unlearn brings unmatched scientific credibility to applying AI in clinical trials.For more information, visit www.unlearn.ai or follow us on LinkedIn and X/Twitter.About Acumen Pharmaceuticals, IncAcumen 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's lead investigational product candidate, sabirnetug (ACU193) is a humanized monoclonal antibody that selectively targets toxic soluble AβOs and which generated positive results in its Phase 1 trial INTERCEPT-AD. Currently, Acumen is conducting, ALTITUDE-AD 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. Topline results are expected in late 2026. More information can be found on www.clinicaltrials.gov, NCT identifier NCT06335173. Acumen is investigating a subcutaneous formulation of sabirnetug using Halozyme's proprietary ENHANZE® drug delivery technology. Acumen is also collaborating with JCR Pharmaceuticals to develop an Enhanced Brain Delivery (EBD™) therapy for Alzheimer's disease utilizing a transferrin-receptor-targeting blood-brain barrier-penetrating technology. The company is headquartered in Newton, Mass.
