CHARLOTTESVILLE, Va. and CARMEL, Ind., March 28, 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 (AD), today reported financial results for the full year ended December 31, 2021, and provided recent business highlights.

“After a transformational year in 2021, highlighted by multiple accomplishments, including our IPO, Acumen is completely focused on executing our business strategy with a primary emphasis on INTERCEPT-AD, our Phase 1 clinical trial investigating the safety, tolerability, pharmacokinetics and target engagement of ACU193 in early Alzheimer’s patients. Based on current progress in the trial and our current plan to report a dataset inclusive of Cohort 7 Day 168 follow up, we now expect to report topline results in the first half of 2023. We have experienced slower than anticipated enrollment due to the COVID-19 pandemic, however our strong cash position has provided us the ability to expand the study footprint to support recruitment and to include a longer follow-up period prior to read out,” said Daniel O’Connell, President and Chief Executive Officer at Acumen. “With the proceeds from our successful IPO last year, we estimate our existing cash, cash equivalents and marketable securities will be sufficient to fund our operating expenses and capital requirements through 2025 based on our current plans.”

Recent Business Highlights and Anticipated Milestones

ACU193 Clinical Development

  • INTERCEPT-AD enrollment continues to progress. Patient screening and enrollment is ongoing for INTERCEPT-AD at eight active sites, with six additional sites selected for potential activation. Acumen anticipates topline results from this trial in the first half of 2023, subject to the rate of site activation and patient recruitment.

  • Clinical trial design for INTERCEPT-AD presented at 2021 Clinical Trials on Alzheimer’s Disease (CTAD) Conference. The presentation included the scientific rationale for targeting toxic AβOs, the clinical trial design of the Phase 1 INTERCEPT-AD study of ACU193, and how the study is designed to establish Proof of Mechanism for ACU193 and serve as the basis for moving to a Phase 2/3 trial.

  • Phase 2/3 clinical trial preparation activities progressing. Given the continued advancement of necessary actions for the planned Phase 2/3 trial, including chronic toxicology and chemistry manufacturing and controls (CMC) activities, Acumen plans to be ready to initiate a Phase 2/3 trial on the success of INTERCEPT-AD results.

Corporate

In the fourth quarter of 2021, Acumen expanded its team with several new appointments. The new team members include Julie Bockenstette, Head of Human Relations; Siew Tin Gan, Head of Clinical Operations; and Stephen Reynolds, Corporate Controller and Treasurer.

“We welcome Julie, Siew Tin and Stephen, who are joining Acumen at a critical time in our company’s growth as we continue to pioneer a new approach to treating Alzheimer’s disease,” said Daniel O’Connell. “We believe their individual experience and collective passion for improving the lives of patients with Alzheimer’s disease will help us move closer to our ambitious goals.”

  • Ms. Bockenstette has more than 20 years of experience in human resources and sales at high-growth companies. Prior to this role, Bockenstette was Vice President of HR and Head of HR at the Diabetes Care Europe and North America division of Roche Diabetes Care. She has also held several key human resources and leadership roles at Elanco Animal Health and Eli Lilly and Co., both in Indiana.

  • Ms. Gan has more than 20 years of experience in clinical research with a history of working in the pharmaceuticals and nutrition industries. Prior to this role, Gan was Senior Clinical Operations Program Leader in Neuroscience at Takeda, in addition to senior research and leadership positions at Danone Nutricia Research (Singapore), Lundbeck (Singapore), and Novo Nordisk (New Jersey).

  • Mr. Reynolds has more than 25 years of finance experience in the healthcare industry. Prior to this role, Reynolds was Global Controller and Treasurer at Envigo RMS in Indianapolis, in addition to several other financial management positions at Roche Diagnostics, LDI and FinishMaster, Eli Lilly and Co., Memry Corporation, Roche Health Solutions, and Assembly Biosciences.

In addition to these appointments, Kim Drapkin, CPA, has been appointed to the Board of Directors effective April 1, 2022. Ms. Drapkin is currently the Chief Financial Officer of Jounce Therapeutics. Ms. Drapkin brings more than 25 years of experience working with private and publicly traded biotechnology and pharmaceutical companies, including building and leading finance functions, raising capital, and leading strategic financial planning. Ms. Drapkin will also serve as the chair of the company’s audit committee.

“I’m incredibly excited to join the Board of Directors of Acumen at this exciting time. We face a massive unmet need in Alzheimer’s disease, and I believe that Acumen’s approach of targeting toxic amyloid-beta oligomers has the potential to transform the treatment of the disease. I look forward to working with the team and the rest of the Board to support the company’s growth and, in particular, the development of ACU193,” said Ms. Drapkin.

2021 Financial Results

  • Cash Balance. As of December 31, 2021, our cash, cash equivalents and marketable securities totaled $225.9 million, compared to cash and cash equivalents of $43.8 million and no marketable securities as of December 31, 2020.

  • Research and Development (R&D) Expenses. R&D expenses were $12.3 million for the twelve-month period ended December 31, 2021, compared to $8.0 million for the twelve-month period ended December 31, 2020. The net increase in research and development expenses in 2021 from 2020 was primarily due to increased costs related to initiating our clinical trial in 2021.

  • General and Administrative (G&A) Expenses. G&A expenses were $7.3 million for the twelve-month period ended December 31, 2021, compared to $1.4 million for the twelve-month period ended December 31, 2020. Following the initial public offering, we added a number of new personnel and a large portion of the other increase is a direct result of our transition from a private to a public company.

  • Loss from Operations. Losses from operations were $19.6 million for the twelve-month period ended December 31, 2021, compared to $7.9 million for the twelve-month period ended December 31, 2020.

  • Net Loss. Net losses were $100.6 million for the twelve-month period ended December 31, 2021, compared to $7.3 million for the twelve-month period ended December 31, 2020. Net losses in 2021 include a non-cash expense of $81.2 million that represents the changes in fair value of Acumen’s Series B tranche liability and Series A-1 warrant liability. The tranche liability and warrant liability were initially recorded at fair value as liabilities on Acumen’s balance sheet and were subsequently re-measured at fair value at the end of each reporting period. The increases in the fair value of these instruments were recognized as a component of other expense. The second tranche of the Series B Preferred Stock financing round closed in June 2021 and, as a result, the remaining value of the tranche liability was reclassified to convertible preferred stock on Acumen’s condensed balance sheet. Additionally, the Series A-1 warrant was exercised in June 2021, and the remaining value of the warrant liability was reclassified to convertible preferred stock on Acumen’s condensed balance sheet. Upon the closing of the initial public offering, all outstanding shares of convertible preferred stock converted into equivalent shares of common stock.

About ACU193

ACU193 is a 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 Pharmaceuticals, 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 toxic soluble 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 a Phase 1 clinical trial involving early Alzheimer’s disease patients.
