Acumen Pharmaceuticals Reports First Quarter 2023 Financial Results and Business Highlights

CHARLOTTESVILLE, Va. and Carmel, Ind., May 09, 2023 (GLOBE NEWSWIRE) — Acumen Pharmaceuticals, Inc. (NASDAQ: ABOS), 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 2023 and provided a business update.

“In the first quarter, we remained focused on executing the Phase I INTERCEPT-AD trial of ACU193, our novel therapeutic for the treatment of early Alzheimer’s disease. We are pleased to confirm our expectation that we will share the first clinical data in the field from a monoclonal antibody with high selectivity for toxic amyloid beta oligomers in the upcoming third quarter,” said Daniel O’Connell, President and Chief Executive Officer of Acumen. “Amid a dynamic and evolving Alzheimer’s landscape, we look forward to reporting clinical evidence of the overall safety profile, pharmacokinetic data, including the potential for monthly dosing, as well as target engagement. We expect that these topline data will serve as the basis for an anticipated interaction with the FDA in the fourth quarter to inform our next phase of development for ACU193.”

Recent Business Highlights and Anticipated Milestones

  • In February 2023, enrollment was completed in our Phase 1 INTERCEPT-AD trial, investigating the safety, tolerability, pharmacokinetics and target engagement of ACU193 in patients with early AD.
    • Acumen continues to anticipate reporting topline results from this trial in the third quarter of 2023.
  • In March 2023, the Company presented research at the International Conference on Alzheimer’s and Parkinson’s Diseases (ADPD).
    • The research demonstrated the utility of a human in vitro model of induced pluripotent stem cell (iPSC)-derived excitatory neurons for a better understanding of which forms of amyloid beta oligomers contribute to the pathogenesis of AD in the human brain. Utilizing human iPSC-derived excitatory neurons as a model, a panel of Aβ detection antibodies, and a panel of globular soluble AβOs plus monomers, the current study found that soluble Aβ size may influence synaptic binding.

First Quarter 2023 Financial Results

  • Cash Balance. As of March 31, 2023, cash, cash equivalents and marketable securities totaled $183.8 million, compared to cash, cash equivalents and marketable securities of $193.4 million as of December 31, 2022. The decrease in cash is related to funding ongoing operations.
  • Research and Development (R&D) Expenses.  R&D expenses were $8.7 million for the three-month period ended March 31, 2023, compared to $6.0 million for the three-month period ended March 31, 2022. The increase in R&D expenses was primarily due to increased costs related to our ongoing clinical trial, as well as nonclinical research and development activity.
  • General and Administrative (G&A) Expenses. G&A expenses were $4.4 million for the three-month period ended March 31, 2023, compared to $3.2 million for the three-month period ended March 31, 2022. The increase in G&A expenses was primarily due to increased costs related to personnel, consulting and travel expenses.
  • Loss from Operations. Losses from operations were $13.1 million for the three-month period ended March 31, 2023, compared to $9.2 million for the three-month period ended March 31, 2022. This increase was due to the increased R&D and G&A expenses over the prior year period.
  • Net Loss. Net loss was $11.3 million for the three-month period ended March 31, 2023, compared to $9.1 million for the three-month period ended March 31, 2022.

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 across all sites. More information can be found on www.clinicaltrials.gov, NCT identifier NCT04931459.

About Acumen Pharmaceuticals, Inc.

Acumen, headquartered in Charlottesville, VA, with clinical operations based in Carmel, IN, 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, ACU193, a humanized monoclonal antibody that selectively targets toxic soluble AβOs in INTERCEPT-AD, a Phase 1 clinical trial involving early Alzheimer’s disease patients.
