NEWTON, Mass., Aug. 15, 2022 (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, 2022, and provided a corporate update.
“I am very pleased with our team’s quick turnaround of our New Drug Application (NDA) resubmission following receipt of the Complete Response Letter (CRL) in response to our ACER-001 NDA for urea cycle disorders (UCDs),” stated Chris Schelling, CEO and Founder of Acer. “We have already announced the U.S. Food & Drug Administration (FDA) has accepted our NDA resubmission for ACER-001 in UCDs, assigned a new PDUFA date of January 15, 2023, and we are awaiting the agency’s inspection of our third-party contract packaging manufacturer. Meanwhile, we have made additional progress on our ACER-001 program, including the submission of an Investigational New Drug (IND) application for clinical investigation in Maple Syrup Urine Disease (MSUD) patients, and the issuance of a key utility patent in China.”
Schelling continued, “In parallel to our efforts in support of ACER-001 development, we also initiated in the second quarter, our Phase 3 pivotal DiSCOVER trial of EDSIVO™ for the treatment of vascular Ehlers-Danlos Syndrome (vEDS) under our Special Protocol Assessment (SPA) agreement with the FDA. Looking ahead, we anticipate topline results in our Phase 2a clinical trial of ACER-801 for the treatment of moderate to severe Vasomotor Symptoms (VMS) in post-menopausal women in Q4 of 2022.”

- In August 2022, the European Commission granted orphan medicinal product designation in the EU to ACER-001 for the potential treatment of MSUD

- In June 2022, promoted Tanya Hayden as Chief Operating Officer. Ms. Hayden has extensive experience in operational excellence and is tasked with commercial and operational readiness for a potential commercial approval and launch of ACER-001 in UCDs. Prior to joining Acer, Ms. Hayden spent 20 years at Lonza, where she was responsible for business unit planning, clinical and commercial contract manufacturing, as well as portfolio program management
- Ended Q2 2022 with $14.5 million in cash and cash equivalents, which Acer believes will be sufficient to fund its currently anticipated operating and capital requirements through Q3 2022

- January 15, 2023: The FDA has assigned a new PDUFA target action date of January 15, 2023, following its acceptance for review of Acer’s resubmitted NDA for ACER-001 for the treatment of patients with UCDs.

- EDSIVO™ (celiprolol)
- Mid-2023: Based on current enrollment rates, Acer anticipates the DiSCOVER trial for celiprolol in patients with COL3A1-positive vEDS will be fully enrolled in mid-2023. Once fully enrolled, the duration of the DiSCOVER trial is currently estimated to be up to approximately 3.5 years to completion (based on statistical power calculations and number of primary events), which will require additional capital beyond Q3 2022. One interim analysis (based on the number of primary events occurring) is also planned at approximately 24 months after full enrollment
Q2 2022 Financial Results
Cash position. Cash and cash equivalents were $14.5 million as of June 30, 2022, compared to $12.7 million as of December 31, 2021. Acer believes its cash and cash equivalents available as of June 30, 2022 will be sufficient to fund its currently anticipated operating and capital requirements through Q3 2022.
Research and Development Expenses. Research and development expenses were $3.4 million, net of collaboration funding of $1.6 million, for the three months ended June 30, 2022, as compared to $1.4 million, net of collaboration funding of $1.0 million, for the three months ended June 30, 2021. This increase of $2.0 million was primarily due to increases in expenses for clinical studies. Research and development expenses for the three months ended June 30, 2022 were comprised of $2.1 million related to ACER-801; $1.8 million related to ACER-001, offset by $1.6 million of collaboration funding; $0.8 million related to EDSIVO; and $0.3 million related to other development activities.
General and Administrative Expenses. General and administrative expenses were $3.6 million, net of collaboration funding of $3.3 million, for the three months ended June 30, 2022, as compared to $2.3 million, net of collaboration funding of $0.6 million, for the three months ended June 30, 2021. This increase of $1.3 million was primarily due to increases in precommercial expenses, audit and consulting fees, and employee-related expenses, partially offset by a decrease in the recognition of the collaboration funding from the Collaboration Agreement with Relief.
Net Loss. Net loss for the three months ended June 30, 2022 was $2.7 million, or $0.17 net loss per share (basic and diluted), compared to a net loss of $3.1 million, or $0.21 net loss per share (basic and diluted), for the three months ended June 30, 2021.
