SAN CARLOS, Calif., Nov. 14, 2023 (GLOBE NEWSWIRE) — Atreca, Inc. (Atreca) (NASDAQ: BCEL), a clinical-stage biotechnology company focused on developing novel therapeutics generated through a unique discovery platform based on interrogation of the active human immune response, today reported financial results for the third quarter ended September 30, 2023, and announced that the Company is implementing a further reduction in its workforce of approximately 40% while maintaining the necessary support to continue exploring potential strategic transactions and business alternatives. “Since our founding, Atreca has leveraged a unique discovery platform to identify numerous antibodies binding novel targets in oncology, as well as infectious and autoimmune disease,” said John Orwin. “We remain focused on advancing APN-497444 through preclinical testing and continue to believe that our approach has potential to unlock meaningful tumor targets undiscoverable by conventional approaches. Nevertheless, given current financial market conditions and the funding needs required to advance ‘444 and our other antibody-drug conjugate programs into clinical development, we have made the difficult decision to further reduce our headcount as we explore strategic alternatives. I’d like to thank all employees impacted for their contributions.” Third Quarter 2023 Financial Results As of September 30, 2023, cash and cash equivalents and investments totaled $21.4 million.Research and development expenses for the three months ended September 30, 2023, were $10.4 million, including non-cash stock-based compensation expense of $1.0 million.General and administrative expenses for the three months ended September 30, 2023, were $5.4 million, including non-cash stock-based compensation expense of $1.3 million.Atreca reported a net loss of $36.2 million, or basic and diluted net loss per share attributable to common stockholders of $0.92, for the quarter ended September 30, 2023.
