Acumen Pharmaceuticals, Inc. (NASDAQ: ABOS) ("Acumen" or the "Company"), 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), today reported financial results for the first quarter of 2024 and provided a business update.
"In the first quarter, our team remained laser-focused on the initiation of ALTITUDE-AD, our Phase 2 study investigating the efficacy and safety of sabirnetug for the treatment of early AD. We announced the first patient dosed in this study just last week. We are encouraged by the level of investigator interest in the potential of sabirnetug to offer a best-in-class therapeutic profile for patients, which is a testament to our strong Phase 1 data package and the relationships our team has built with clinical sites," Daniel O'Connell, Chief Executive Officer of Acumen. "We continue to expect to initiate a Phase 1 study with a subcutaneous form of sabirnetug in mid-2024 in an effort to extend the product profile and offer administration optionality for patients. We remain committed to delivering on our strategic priority to advance the clinical development of sabirnetug efficiently and thoughtfully."
Recent Highlights and Anticipated Milestones
Sabirnetug (ACU193) Clinical Development
- In May 2024, the Company announced the first patient dosed in ALTITUDE-AD, a Phase 2 study to investigate the clinical efficacy and safety of sabirnetug for the treatment of early AD.
- In April 2024, the Company presented  biomarker, safety and target engagement analyses from the Phase 1 INTERCEPT-AD study in  AD at the American Academy of Neurology Annual Meeting.
- The results build upon Acumen's prior presentations at the AD/PD™ 2024 Annual Meeting and positive topline data first announced in July 2023, highlighting sabirnetug as the first humanized monoclonal antibody to clinically demonstrate selective target engagement of synaptotoxic AβOs. Additional information can be found here.
- In April 2024, the Company announced a collaboration agreement with Lonza, a global partner to the pharmaceutical, biotech and nutraceutical markets.
- The agreement covers the manufacture of sabirnetug for clinical development and commercialization, if approved. Acumen will leverage Lonza's regulatory expertise, extensive experience in antibody manufacturing, and global manufacturing network from 2,000L to 20,000L.
- The Company expects to initiate a Phase 1 study to support a subcutaneous dosing option of sabirnetug in mid-2024.
First Quarter 2024 Financial Results
- Cash Balance. As of March 31, 2024, cash, cash equivalents and marketable securities totaled $296.6 million, compared to cash, cash equivalents and marketable securities of $306.1 million as of December 31, 2023. The decrease in cash is related to funding ongoing operations. Cash is expected to support current clinical and operational activities into the first half of 2027.
- Research and Development (R&D) Expenses. R&D expenses were $12.4 million for the three month period ended March 31, 2024, compared to $8.7 million for the three month period ended March 31, 2023. The increase in R&D expenses was primarily due to increased costs related to personnel, manufacturing and materials costs, consulting, and other costs.
- General and Administrative (G&A) Expenses. G&A were $5.3 million for the three month period ended March 31, 2024, compared to $4.4 million for the three month period ended March 31, 2023. The increase in G&A expenses was primarily due to increased costs related to personnel.
- Loss from Operations. Losses from operations were $17.8 million for the three month period ended March 31, 2024, compared to $13.1 million for the three month period ended March 31, 2023. This increase was due to the increased R&D and G&A expenses over the prior year period.
- Net Loss. Net loss was $14.9 million for the three-month period ended March 31, 2024, compared to $11.3 million for the three month period ended March 31, 2023.

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 was previously evaluated in a Phase 1 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 will enroll approximately 540 individuals with early Alzheimer's disease (mild cognitive impairment or mild dementia due to AD). The global study is currently enrolling at multiple investigative sites located in the United States and Canada with plans for additional sites in Europe and the UK. More information can be found on www.clinicaltrials.gov, NCT identifier NCT06335173.
About INTERCEPT-AD (Phase 1)
Completed in 2023, INTERCEPT-AD was 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 sabirnetug 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 sabirnetug. The INTERCEPT-AD study consisted of single-ascending-dose (SAD) and multiple-ascending-dose (MAD) cohorts and was designed to evaluate the safety, tolerability, pharmacokinetics (PK), and target engagement of intravenous doses of sabirnetug. More information can be found on www.clinicaltrials.gov , NCT identifier NCT04931459.
