Acer Therapeutics Reports Second Quarter 2020 Financial Results and Provides Corporate Update

Advanced expanded pipeline of clinical stage product candidates, including emetine for COVID-19 and ACER-001 for Urea Cycle Disorders

NEWTON, Mass., Aug. 13, 2020 (GLOBE NEWSWIRE) -- Acer Therapeutics Inc. (Nasdaq: ACER), a pharmaceutical company focused on the acquisition, development and commercialization of therapies for serious rare and life-threatening diseases with significant unmet medical needs, today reported financial results for the second quarter ended June 30, 2020, and provided an update on the Company’s recent corporate developments.

“The second quarter of 2020 was marked by significant progress in two of our lead programs – emetine and ACER-001,” said Chris Schelling, CEO and Founder of Acer. “The need for a therapeutic to treat confirmed COVID-19 patients before they progress and become hospitalized remains a global priority. The team has been working diligently for the past several months to advance emetine from a concept to a pre-IND opportunity and we look forward to the clinical evaluation of emetine, subject to the availability of the required capital. Regarding ACER-001, we reported encouraging new data showing that when ACER-001 is administered in a fasted state it may provide better disease management over currently approved therapies for UCDs that require administration with food. To that end, we submitted a Type C briefing package to the FDA to discuss these results and are expecting feedback later in the third quarter. We continue to target an ACER-001 NDA filing in the first half of 2021, subject to additional capital.”

Second Quarter 2020 and Recent Highlights

• Emetine

  • Announced a research collaboration agreement with the National Center for Advancing Translational Sciences (NCATS), one of the National Institutes of Health (NIH), to develop emetine hydrochloride as a potential treatment for COVID-19, the disease caused by infection with the SARS-CoV-2 coronavirus

  • Working with federal agencies and private research organizations in an effort to secure non-dilutive funding in support of emetine development

  • Obtained multiple rounds of pre-Investigational New Drug (IND) feedback from the Division of Antivirals (DAV) at the U.S. Food and Drug Administration (FDA)

  • Secured active pharmaceutical ingredient (API) from extract for initiation of the planned Phase 2/3 trial evaluating emetine in high-risk COVID-19 outpatients, assuming the availability of capital. In parallel, we successfully established a fully synthetic development pathway for API exclusively in the U.S.

• ACER-001

  • Announced results from a food effect study in healthy volunteers showing that administration of ACER-001 in fasted state increased systemic exposure of phenylbutyrate (PBA) levels compared to fed state, which according to in silico modeling may provide improved disease management in patients with urea cycle disorders (UCDs) when compared to currently approved treatments requiring administration with food

  • Submitted a Type C briefing package to the FDA

• EDSIVO™

  • Continued to assess possible paths forward that could provide the confirmatory evidence needed to demonstrate the substantial evidence of effectiveness needed to support a potential resubmission of the EDSIVO™ NDA

• Osanetant

  • Advanced API manufacturing and other steps to support IND submission

• Corporate

  • Hired Stacey Bain, Ph.D. as Vice President, Clinical Operations, who brings 22 years of international clinical operational and drug development experience in pharmaceutical, biotechnology, and clinical research organization settings

  • Ended the second quarter with $5.9 million in cash and cash equivalents. Acer believes its cash position at the end of the second quarter, combined with an additional $4.7 million of net proceeds subsequently received from sales of common stock from the ATM facility and the insider private placement of common stock, will be sufficient to fund its current operations into the first quarter of 2021, excluding support for the planned emetine Phase 2/3 clinical trial

Upcoming Milestones

• Emetine

  • Seek to obtain potential non-dilutive funding

  • Targeting in the first half of 2021 an IND submission and clearance, followed by potential initiation of the planned Phase 2/3 trial evaluating emetine in high-risk COVID-19 outpatients, subject to ongoing discussions with the FDA and additional capital

• ACER-001

  • Anticipate submitting NDA for urea cycle disorders (UCDs) in the first half of 2021, subject to additional capital, and assuming successful completion of nonclinical work and evaluation of long-term product stability data

• EDSIVO™

  • Expect to request a meeting with FDA by the end of fourth quarter of 2020 to discuss Acer’s proposed plan to provide sufficient confirmatory evidence and, if successful, potentially satisfy the substantial evidence of effectiveness needed to support a possible resubmission of the EDSIVO™ NDA. Neither EDSIVO™ NDA resubmission nor approval is assured

• Osanetant

  • Anticipate submitting osanetant IND in the first quarter of 2021

  • Targeting initiation of Phase 1/2 pharmacokinetic/pharmocodynamic and safety trial in the first half of 2021, subject to additional capital, that will evaluate osanetant in patients with medically and/or surgically induced vasomotor symptoms (iVMS)

Financial Results for the Second Quarter 2020

Cash position. Cash and cash equivalents were $5.9 million as of June 30, 2020, compared to $12.1 million as of December 31, 2019. Acer believes its cash position at the end of the second quarter, combined with an additional $4.7 million of net proceeds subsequently received from sales of common stock under the ATM facility and the insider private placement of common stock, will be sufficient to fund its current operations into the first quarter of 2021, excluding support for the planned emetine Phase 2/3 clinical trial.

Research and Development Expenses. Research and development expenses were $2.8 million for the three months ended June 30, 2020, compared to $4.2 million for the three months ended June 30, 2019. This decrease of $1.4 million was primarily due to decreases in employee-related expenses and clinical and regulatory consulting as a direct result of the Complete Response Letter for EDSIVO™ received from the FDA in June 2019, partially offset by increases in contract research and contract manufacturing expenses. Research and development expenses for the three months ended June 30, 2020 were primarily comprised of $1.0 million related to emetine, $0.9 million related to ACER-001, and $0.8 million related to osanetant.

General and Administrative Expenses. General and administrative expenses were $3.0 million for the three months ended June 30, 2020, compared to $6.9 million for the three months ended June 30, 2019. This decrease of $3.9 million was primarily due to decreases in precommercial and employee-related expenses as a direct result of the Complete Response Letter for EDSIVO™ received from the FDA in June 2019, partially offset by costs related to implementing Acer’s equity line purchase agreement with Lincoln Park Capital Fund, LLC.

Net Loss. Net loss for the three months ended June 30, 2020 was $5.8 million, or $0.56 net loss per share (basic and diluted), compared to a net loss of $11.0 million, or $1.09 net loss per share (basic and diluted), for the three months ended June 30, 2019.
