NEWTON, Mass., March 01, 2021 (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 fourth quarter and full year ended December 31, 2020 and provided an update on the Company’s recent corporate developments.

“In spite of the challenges presented by a global pandemic in 2020, we continued to advance our existing programs while expanding our pipeline,” said Chris Schelling, CEO and Founder of Acer. “As a result, we anticipate a number of key milestones next quarter, including a proposed ACER-001 pre-NDA meeting with FDA, continuing to work toward a potential ACER-001 collaboration and license agreement with Relief Therapeutics pursuant to the existing option agreement between the companies, and a Type B meeting with the FDA to discuss a possible path forward for EDSIVO™. We are also working toward initiation of a Phase 2 clinical trial of osanetant in BRCA-positive patients with induced vasomotor symptoms in the fourth quarter of 2021, subject to successful IND filing and additional capital, and continuing to seek non-dilutive capital to advance emetine development.”

Fourth Quarter 2020 and Recent Highlights

• ACER-001
  • Signed an Option Agreement with Relief Therapeutics Holding AG on January 25, 2021 providing Relief with exclusivity until June 30, 2021 for the right to pursue a potential collaboration and license agreement for worldwide development and commercialization for ACER-001. In return, Acer received a $1.0 million upfront nonrefundable payment and a $4.0 million secured loan from Relief
  • Announced in February 2021 topline results from Acer’s bioequivalence trial in which ACER-001 showed similar relative bioavailability compared to BUPHENYL

    )
    
  • Submitted a Type B meeting request to the FDA in February 2021 to discuss Acer’s proposed plan to collect additional data and provide confirmatory evidence in support of celiprolol’s potential benefit in treating COL3A1-positive vEDS patients

• ACER-801 (osanetant)
  • Completed active pharmaceutical ingredient (API) manufacturing and advanced other development activities to support an Investigational New Drug Application (IND) submission

• Corporate
  • Promoted Jefferson Davis to Chief Business Officer in February 2021. A veteran life science executive and transaction specialist with over 25 years of experience in business and corporate development, Mr. Davis has led or supported over 40 transactions with an aggregate value of more than $2 billion across all major therapeutic platforms, including antibodies, small molecules, aptamers, gene therapy, vaccines, and proteins
    
  • Ended the fourth quarter with $5.8 million in cash and cash equivalents. Acer believes its cash position as of December 31, 2020, combined with an additional $3.2 million of net proceeds subsequently received from the sales of common stock under its ATM facility and through its equity line purchase agreement with Lincoln Park Capital, along with the $1.0 million nonrefundable payment and $4.0 million secured loan received from Relief Therapeutics following the signing of the ACER-001 Option Agreement, will be sufficient to fund its operations into the third quarter of 2021
    

Upcoming Milestones

• ACER-001
  • Q2 2021: Targeting a pre-New Drug Application (NDA) meeting with the FDA in the second quarter of 2021, assuming successful completion of the ongoing development activities
    
  • Mid-2021: ACER-001 NDA submission for treatment of patients with Urea Cycle Disorders (UCDs) is anticipated in mid-2021, provided that no additional data is requested by the FDA during Acer’s pre-NDA meeting and ongoing development activities are successfully completed (including evaluation of long-term product stability data)

• EDSIVO™
  • Q2 2021: Obtain FDA feedback from a Type B meeting in the second quarter of 2021 regarding Acer’s proposed plan to collect additional data which, if discussions are successful and the collected data is sufficient, could potentially satisfy the substantial evidence of effectiveness needed to support a resubmission of the EDSIVO™ NDA (although neither EDSIVO™ NDA resubmission nor approval is assured)
• ACER-801 (osanetant)
  • Q3 2021: IND submission for osanetant is anticipated in the third quarter of 2021
    
  • Q4 2021: Initiation of a Phase 2 clinical trial of osanetant in BRCA-positive patients who have undergone a prophylactic bilateral salpingo-oophorectomy (PBSO) is expected in the fourth quarter of 2021, dependent upon successful IND filing and subject to additional capital

• ACER-2820 (emetine)
  • Ongoing: Further advancement of the emetine program for infectious diseases, including COVID-19, is dependent on Acer’s ability to raise non-dilutive capital
    
  • Ongoing: The Company believes that most of the emetine IND-enabling work is in progress or complete, and intends to minimize future emetine spending as it continues to work with federal agencies and private research organizations toward the goal of securing non-dilutive funding
    

Financial Results for the Fourth Quarter and Full Year 2020

Cash position.

Cash and cash equivalents were $5.8 million as of December 31, 2020, compared to $12.1 million as of December 31, 2019. Acer believes its cash and cash equivalents available as of December 31, 2020, combined with an additional $3.2 million of net proceeds subsequently received from the sales of common stock under its ATM facility and through its equity line purchase agreement with Lincoln Park Capital, along with the $1.0 million nonrefundable payment and $4.0 million secured loan received from Relief Therapeutics following the signing of the ACER-001 Option Agreement, will be sufficient to fund its operations into the third quarter of 2021.

Research and Development Expenses.

Research and development expenses were $3.5 million for the three months ended December 31, 2020, compared to $2.8 million for the three months ended December 31, 2019. Research and development expenses for the three months ended December 31, 2020 were comprised of $1.3 million related to ACER-001, $1.5 million related to emetine, $0.6 million related to osanetant, and $0.1 million related to EDSIVO™. Research and development expenses were $11.8 million for the year ended December 31, 2020, compared to $13.9 million for the year ended December 31, 2019. This decrease of approximately $2.1 million was primarily due to decreases in employee-related expense and in spending related to clinical and other consulting services, partially offset by an increase in contract research expenses.

General and Administrative Expenses.

General and administrative expenses were $2.7 million for the three months ended December 31, 2020, compared to $2.4 million for the three months ended December 31, 2019. General and administrative expenses were $11.0 million for the year ended December 31, 2020, compared to $16.0 million for the year ended December 31, 2019. This decrease of $5.0 million was primarily due to decreases in employee-related expenses and precommercial activities expenses, partially offset by an increase in legal expenses. This decrease in employee-related expenses resulted from a decrease in headcount as a consequence of the restructuring initiative undertaken after receipt of the Complete Response Letter from the FDA for EDSIVO™ in June 2019.

Net Loss.

Net loss for the three months ended December 31, 2020 was $6.2 million, or $0.50 net loss per share (basic and diluted), compared to a net loss of $5.2 million, or $0.51 net loss per share (basic and diluted), for the three months ended December 31, 2019. Net loss for the year ended December 31, 2020 was $22.9 million, or $2.06 loss per share (basic and diluted), compared to a net loss of $29.4 million, or $2.91 loss per share (basic and diluted), for the year ended December 31, 2019.
