Closed Merger and Concurrent $15.7M Financing

Announced Positive Results from Pivotal Clinical Trial of EDSIVO™ (celiprolol) for
Treatment of vEDS

CAMBRIDGE, Mass., Nov. 13, 2017 (GLOBE NEWSWIRE) — Acer Therapeutics Inc. (Nasdaq:ACER), a pharmaceutical company focused on the acquisition, development and commercialization of therapies for serious rare and ultra-rare diseases with critical unmet medical need, today reported financial results for the quarter ended September 30, 2017 and provided an update on the Company’s recent corporate developments.

“The third quarter was transformative for Acer. We became a public Nasdaq-listed company, closed a concurrent financing and announced positive results from our pivotal clinical trial of EDSIVO™, each a critical step in bringing us closer to our goal of becoming a leading pharmaceutical company that acquires, develops and commercializes therapies for the treatment of patients with serious rare and ultra-rare diseases with critical unmet medical need,” said Chris Schelling, CEO and Founder of Acer. “We continue to successfully advance our lead product candidate, EDSIVO™, a potential life-saving therapy for patients with vEDS. We believe that our current cash position will allow us to advance EDSIVO™ through NDA submission with the FDA in the first half of 2018. As a public company, we look forward to advancing and expanding our pipeline with the goal of bringing multiple products to patients over the next several years.”

Corporate Activities

  • Closed merger with Opexa Therapeutics, Inc. and $15.7 million concurrent financing, and common stock commenced trading on Nasdaq Capital Market.
  • Announced positive results from the pivotal clinical trial of EDSIVO™ (celiprolol) for the treatment of vascular Ehlers-Danlos Syndrome (vEDS). Acer’s retrospective source-verified analysis of the trial data, including the primary and secondary endpoints, confirmed the data from a previously published randomized controlled clinical study of celiprolol(1). Acer plans to use such pivotal clinical data to support a New Drug Application (NDA) regulatory filing with the U.S. Food and Drug Administration (FDA) in the first half of 2018.

Financial Results for the Quarter Ended September 30, 2017

Cash position.  Cash and cash equivalents were $8.4 million as of September 30, 2017, compared to $1.8 million as of December 31, 2016.

Research and Development Expenses.  Research and development expenses were $2.1 million for the three months ended September 30, 2017, compared with $1.6 million for the three months ended September 30, 2016. The increase in expenses is primarily due to an increase in spending for clinical development and manufacturing services related to EDSIVO™. 

General and Administrative Expenses.  General and administrative expenses were $1.3 million for the three months ended September 30, 2017, compared with $0.3 million for the three months ended September 30, 2016. The increase in expenses is primarily due to an increase in professional services and pre-commercial launch costs related to EDSIVO™.

Net Loss.  Net loss for the three months ended September 30, 2017 was $3.5 million, or $1.09 loss per share (basic and diluted), compared with a net loss of $1.9 million, or $0.77 loss per share (basic and diluted), for the three months ended September 30, 2016.

About Acer Therapeutics
Acer, headquartered in Cambridge, MA, is a pharmaceutical company focused on the acquisition, development and commercialization of therapies for patients with serious rare and ultra-rare diseases with critical unmet medical need. Acer’s late-stage clinical pipeline includes two candidates for severe genetic disorders for which there are few or no FDA-approved treatments: EDSIVO™ (celiprolol) for vEDS, and ACER-001 (a fully taste-masked, immediate release formulation of sodium phenylbutyrate) for urea cycle disorders (UCD) and Maple Syrup Urine Disease (MSUD). There are no FDA-approved drugs for vEDS and MSUD and limited options for UCD, which collectively impact more than 4,000 patients in the United States. Acer’s product candidates have clinical proof-of-concept and mechanistic differentiation, and Acer intends to seek approval for them in the U.S. by using the regulatory pathway established under section 505(b)(2) of the Federal Food, Drug, and Cosmetic Act, or FFDCA, that allows an applicant to rely for approval at least in part on third-party data, which is expected to expedite the preparation, submission, and potential approval of a marketing application.
