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

NEWTON, Mass., May 14, 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 first quarter ended March 31, 2020 and provided an update on the Company’s recent corporate developments.

“Over the last several months, we made significant progress in the expansion and further diversification of our product pipeline with the recent addition of emetine, a broad-acting and potent antiviral for the treatment of COVID-19 patients,” said Chris Schelling, CEO and Founder of Acer. “We are very pleased to be collaborating with NCATS on the development of emetine and look forward to advancing this important program. We continued to advance our ACER-001 program for UCDs following the successful completion of our pivotal bioequivalence trial and are targeting NDA submission in early 2021, subject to additional capital. In addition, we are preparing to submit an IND for osanetant by the end of the year, and we intend to initiate a Phase 1/2 trial in patients with induced vasomotor symptoms in the first quarter of next year, subject to additional capital. To that end, we entered into a stock purchase agreement with Lincoln Park Capital.”

First 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
  °  In discussion with the Division of Antivirals (DAV) at FDA after receiving its written responses to the Company’s pre-Investigational New Drug (pre-IND) package
  °  Presented at the Biomedical Advanced Research and Development Authority (BARDA) CoronaWatch meeting on May 7, 2020. BARDA CoronaWatch is a funding program providing government support for selected coronavirus projects
• ACER-001
  °  Initiated nonclinical work and evaluation of long-term product stability following the successful completion of the pivotal trial showing that ACER-001 is bioequivalent to BUPHENYL^® (sodium phenylbutyrate)
• EDSIVO™
  °  Received appeal response from the FDA’s Office of New Drugs (OND) stating it denied Acer’s appeal of the Complete Response Letter (CRL) in relation to the New Drug Application (NDA) for EDSIVO™. Acer is assessing possible paths forward, as described in the OND’s response, that could provide the substantial evidence of effectiveness needed to support a potential resubmission of the EDSIVO™ NDA
• Ended the first quarter with $7.0 million in cash and cash equivalents. Acer believes its cash position will be sufficient to fund its current operations into the fourth quarter of 2020, excluding support for a planned emetine clinical trial and for EDSIVO™ development and precommercial activities
• Announced a common stock purchase agreement to potentially sell up to $15 million worth of shares to Lincoln Park Capital Fund, LLC over a 36-month period, following the filing and effectiveness of a registration statement and subject to various limitations including those under the Nasdaq listing rules

Upcoming Milestones

• Emetine
  °  Pursuing several potential financing options, including federally-funded research and grants, to support emetine development
  °  Working toward an IND submission in mid-2020
  °  Targeting initiation in the third quarter of 2020, subject to additional capital, an adaptive design Phase 2/3 randomized, blinded, placebo-controlled multi-center trial in high-risk, symptomatic adult COVID-19 patients not requiring hospitalization
• ACER-001
  °  Anticipate submitting NDA for urea cycle disorders (UCDs) in the first quarter of 2021, subject to additional capital, and assuming successful completion of nonclinical work and evaluation of long-term product stability data
• Osanetant
  °  Anticipate submitting osanetant IND in the fourth quarter of 2020
  °  Targeting initiation of Phase 1/2 pharmacokinetic/pharmocodynamic and safety trial in the first quarter of 2021, subject to additional capital, evaluating osanetant in patients with medically and/or surgically induced vasomotor symptoms (iVMS) in which Hormone Replacement Therapy (HRT) is contraindicated
• EDSIVO™
  °  Continuing to evaluate possible next steps with the goal of resubmission of the EDSIVO™ NDA. Neither resubmission nor EDSIVO™ approval is assured

Financial Results for the First Quarter 2020

Cash position. Cash and cash equivalents were $7.0 million as of March 31, 2020, compared to $12.1 million as of December 31, 2019. Acer believes its cash position will be sufficient to fund its current operations into the fourth quarter of 2020, excluding support for a planned emetine clinical trial and for EDSIVO™ development and precommercial activities.

Research and Development Expenses. Research and development expenses were $2.3 million for the three months ended March 31, 2020, compared to $3.9 million for the three months ended March 31, 2019. This decrease of approximately $1.6 million was primarily due to decreases in clinical and regulatory consulting, contract manufacturing, 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 an increase in contract research expenses. Research and development expenses for the three months ended March 31, 2020 were primarily comprised of approximately $0.5 million related to EDSIVO™ and approximately $1.4 million related to ACER-001.

General and Administrative Expenses. General and administrative expenses were $2.6 million for the three months ended March 31, 2020, compared to $4.2 million for the three months ended March 31, 2019. This decrease of $1.6 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.

Net Loss. Net loss for the three months ended March 31, 2020 was $4.9 million, or $0.49 net loss per share (basic and diluted), compared to a net loss of $8.0 million, or $0.79 net loss per share (basic and diluted), for the three months ended March 31, 2019.
