Atreca to Present Analyses of Active B Cell Responses in Nearly 200 Cancer Patients Leading to Identification of More Than 1,000 Antibodies Targeting Non-Autologous Tumor

November 15, 2018

REDWOOD CITY, Calif.--(BUSINESS WIRE)--Nov 15, 2018--Atreca, Inc., a biotechnology company focused on developing novel therapeutics based on a deep understanding of the human immune response, announced today a presentation describing use of the Company’s proprietary Discovery Engine, featuring the Company’s Immune Repertoire Capture ® (IRC™) technology, to characterize active B cell immune responses in nearly 200 cancer patients and to identify more than 1,000 tumor-targeting antibodies that bind to “public” tumor antigens. The presentation, entitled “Identification of Functional Antitumor Antibodies from Immunoglobulin Sequence Repertoires of Cancer Patients,” will be delivered by Daniel Emerling, Ph.D., Atreca’s Senior Vice President, Research, on Friday, November 16, 2018 at 1:05 p.m. Western European Time at the 10th Annual Protein and Antibody Engineering Summit (PEGS) Europe, taking place at the Lisbon Congress Center in Lisbon, Portugal, November 12-16, 2018.

“Our unique discovery platform enables us to identify, in an industrialized manner, functional antibodies generated by the active immune responses of cancer patients responding to therapy,” said Tito A. Serafini, Ph.D., Chief Strategy Officer and an Atreca founder. “The results presented at this conference describe analyses of such antibodies from nearly 200 patients, including the identification of more than 1,000 patient antibodies that target non-autologous tumor selectively across multiple tumor types by binding to public antigens. We are using this library of tumor-targeting antibodies to develop therapeutics designed to treat large patient groups, while continuing to discover additional antibodies to add to our library. Our first program to emerge from our platform, ATRC-101, is anticipated to enter clinical development in 2019.”
