CHARLOTTESVILLE, Va. and CARMEL, Ind., Aug. 15, 2022 (GLOBE NEWSWIRE) --  Acumen Pharmaceuticals, Inc. (NASDAQ: ABOS), a clinical-stage biopharmaceutical company focused on the development of novel targeted therapeutics for Alzheimer’s disease, today reported financial results for the quarter ended June 30, 2022 and provided a business update.

“We continue to make progress advancing INTERCEPT-AD, our Phase 1 clinical trial investigating the safety, tolerability, pharmacokinetics and target engagement of ACU193 in patients with early AD. We remain on track to report topline results in the first half of 2023,” said Daniel O’Connell, President and Chief Executive Officer of Acumen. “Importantly, based on our current plans, we expect our existing cash, cash equivalents and marketable securities to be sufficient to fund our operating expenses and capital expenditure requirements through 2025.”

Recent Business Highlights and Anticipated Milestones

ACU193 Clinical Development

• INTERCEPT-AD enrollment remains ongoing. Patient screening and enrollment is continuing for INTERCEPT-AD. At present, we have 15 active clinical trial sites recruiting patients for INTERCEPT-AD. Acumen anticipates topline data from this trial in the first half of 2023.

• Presentation of methodology for synthetic model assay to potentially standardize the study of soluble AβOs. Methodology was recently presented in a poster, “Preparation and qualification of soluble amyloid beta oligomers for use in bioanalytic assays supporting Alzheimer’s disease therapeutics” (P4-178), at the 2022 Alzheimer’s Association International Conference. This presentation discussed utilizing Aβ-derived diffusible ligands (ADDLs) as a synthetic AβO model reagent to aid in standardization of AβO assays, including the use of ADDLs as a potential quantitative reference standard in potency and PK assays, and possibly to better understand the AβO specificity and selectivity of Aβ-targeting antibodies.
• Phase 2/3 clinical trial preparation activities progressing. Acumen anticipates initiating a Phase 2/3 trial for ACU193 following completion of INTERCEPT-AD, if successful, and subsequent consultation and feedback from the FDA. Chronic toxicology and chemistry manufacturing and controls (CMC) activities are ongoing to support readiness.

Corporate and Board

• Acumen continues to expand its team with new appointments. In Q2 2022, we hired Liean Schenck, MS as our VP, Head of Chemistry, Manufacturing and Controls (CMC). Ms. Schenck brings over 25 years of pharmaceutical industry experience in biologics process development, manufacturing, and CMC program management and has been responsible for CMC delivery of three commercial products since 2016 in her prior experience with other companies. Ms. Schenck started her career at Lonza Biologics in fermentation development before spending more than 20 years at Eli Lilly and Company in various CMC roles. In her most recent position, she served as Head of CMC program management at Novavax.
• Dr. Jeffrey Sevigny, the Chief Medical Officer of Prevail Therapeutics, Inc., a wholly owned subsidiary of Eli Lilly and Company, has departed from the Board effective August 12, 2022. Dr. Sevigny's departure was due to requirements of his current employment and not due to any disagreement with the Company. Dr. Sevigny joined Acumen’s Board in 2019 and has made valuable contributions to the company. “We thank Jeff for his service and support of Acumen over the last three years,” said Dan O’Connell, Chief Executive Officer of Acumen. “His extensive experience and detailed knowledge of clinical translation and neuroscience have been highly valued at Acumen as we have grown, and his early commitment and support of our program and team are greatly appreciated.”

Second Quarter 2022 Financial Results

• Cash Balance. As of June 30, 2022, cash, cash equivalents and marketable securities totaled $209.9 million, compared to cash, cash equivalents and marketable securities of $225.9 million as of December 31, 2021. The decrease in cash is related to funding ongoing operations.
• Research and Development (R&D) Expenses. R&D expenses were $7.3 million for the three-month period ended June 30, 2022, compared to $2.3 million for the three-month period ended June 30, 2021. The increase in research and development expenses was due to increased costs related to our ongoing clinical trial, which was initiated in 2021 and started enrolling patients in the second half of 2021, as well as nonclinical research and development activity.

• General and Administrative (G&A) Expenses. G&A expenses were $3.1 million for the three-month period ended June 30, 2022, compared to $1.2 million for the three-month period ended June 30, 2021.   The increase in general and administrative expenses was primarily due to increased costs related to personnel, insurance, legal, marketing and recruiting expenses.
• Loss from Operations.  Losses from operations were $10.4 million for the three-month period ended June 30, 2022, compared to $3.4 million for the three-month period ended June 30, 2021. This increase was due to the increased R&D and G&A expenses over the prior year period.
• Net Loss. Net loss was $10.2 million for the three-month period ended June 30, 2022, compared to $61.4 million for the three-month period ended June 30, 2021. Net losses in the 2021 period includes a $57.9 million non-cash expense that represents the changes in fair value of Acumen’s Series B tranche liability and Series A-1 warrant liability. The remaining increase relates to increased operating expenses.

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 what a growing body of evidence indicates is a primary underlying cause of the neurodegenerative process in AD.

About INTERCEPT-AD

Approximately 62 individuals with early AD (mild cognitive impairment or mild dementia due to AD) are expected to be randomized into this double-blind, placebo-controlled, first-in-human study of ACU193. INTERCEPT-AD is designed to establish safety and proof of mechanism. It 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 is enrolling at multiple investigative sites located in the United States. 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 disease-modifying approach to treat Alzheimer’s disease. Acumen’s scientific founders pioneered research on AβOs, which a growing body of evidence indicates are primary 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.
