General and administrative expenses were $2.5 million for the three months ended September 30, 2019 compared to $1.7 million for the three months ended September 30, 2018.

The increase in loss per share (basic and diluted) was driven largely by increases in expenses related to manufacturing services, partially offset by  an increase in the number of shares outstanding at September 30, 2019 as compared to September 30, 2018.For additional information, please see Acer’s Quarterly Report on Form 10-Q filed today with the SEC.About Acer Therapeutics Inc.Acer is a pharmaceutical company focused on the acquisition, development and commercialization of therapies for serious rare and life-threatening diseases with significant unmet medical needs. Acer’s pipeline includes three clinical-stage pharmaceutical product candidates: EDSIVO™ (celiprolol), for the treatment of vascular Ehlers-Danlos syndrome (vEDS) in patients with a confirmed type III collagen (COL3A1) mutation; ACER-001 (a fully taste-masked, immediate release formulation of sodium phenylbutyrate), for the treatment of various inborn errors of metabolism, including urea cycle disorders (UCDs) and Maple Syrup Urine Disease (MSUD); and osanetant, for the treatment of induced Vasomotor Symptoms (iVMS) where Hormone Replacement Therapy (HRT) is likely contraindicated.
