Acumen Pharmaceuticals Extends Collaboration With Lonza to Add Drug Product Manufacturing of Sabirnetug for Early Alzheimer’s Disease

Acumen Pharmaceuticals, Inc. recently announced it has extended its collaboration with Lonza to enable the potential future commercial launch of sabirnetug (ACU193).

Sabirnetug is the first humanized monoclonal antibody to clinically demonstrate selective target engagement of AβOs in AD patients. Soluble AβOs are a highly toxic form of Aβ that begin to accumulate before a clinical diagnosis of AD and are an early and persistent trigger of synaptic dysfunction and neurodegeneration. Acumen is developing sabirnetug as a potential next generation antibody treatment for early AD. Acumen is currently enrolling patients in the ALTITUDE sabirnetug -AD study, a Phase 2 clinical trial designed to evaluate the clinical efficacy and safety of intravenous sabirnetug in patients with early AD. Acumen is also evaluating a subcutaneous formulation of sabirnetug in a Phase 1 pharmacokinetic comparison study in healthy volunteers.

The extended collaboration builds upon an existing successful relationship between the two companies, in which Lonza provides DS manufacturing for the Phase 2 clinical supply of sabirnetug. Under the terms of the extended agreement, Lonza will manufacture cGMP DP of sabirnetug for the ongoing and future clinical phases and support the potential commercial launch at its industry-leading state-of-the-art DP manufacturing facility in Visp, Switzerland. Lonza will also provide quality control and stability testing as part of the collaboration.

Peter Droc, Head of Drug Product Services, Lonza, said “Our team of experts has extensive experience in supporting the clinical and commercial manufacture of drug products. In line with our strategy to offer an integrated end-to-end offering for biologics manufacturing, we are looking forward to collaborating with Acumen to advance its innovative and promising drug candidate in the clinic and beyond.”

James Doherty, President and Chief Development Officer, Acumen Pharmaceuticals, added “The extension of our collaboration comes at a time when we’re advancing our clinical programs for sabirnetug with more than 50 Phase 2 sites activated across the US, Canada, UK, and EU. We look forward to continuing our work with Lonza and delivering a potential next-generation treatment for early Alzheimer’s disease.”

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 US FDA and is currently being evaluated in a Phase 2 study in patients with early AD.

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, MA. For more information, visit www.acumenpharm.com.
