Atreca Reports First Quarter 2021 Financial Results and Recent Corporate Developments


SAN CARLOS Calif., May 13, 2021 (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 announced financial results for the first quarter ended March 31, 2021, and provided an overview of recent developments.

"The first few months of 2021 have been a productive period at Atreca, and we look forward to reporting initial summary data from our Phase 1b trial of ATRC-101 in July of this year,” said John Orwin, Chief Executive Officer. "We are making good progress enrolling the monotherapy cohorts, and are moving quickly to commence the combination cohorts evaluating ATRC-101 with both checkpoint inhibitors targeting the PD-1/PD-L1 axis and with chemotherapy. We also continue to advance our pre-clinical pipeline and are excited to announce our next program, targeting EphA2.”

Recent Developments and Highlights

ATRC-101 Clinical Update        

To date, 20 patients have been enrolled and treated in the first-in-human trial evaluating ATRC-101 in multiple solid tumor cancers. Atreca has completed enrollment in the fourth cohort (10 mg/kg) of the dose escalation portion of the trial, and all patients treated at that dose have now completed the 21 day dose-limiting toxicity (DLT) assessment period. No DLTs have been observed in the trial. Atreca and its investigators decided, out of an abundance of caution, to enroll three additional patients in the fourth dose cohort (10 mg/kg), after the first two patients enrolled experienced rapid deterioration associated with disease progression, assessed as unrelated to ATRC-101, relatively soon after completion of the DLT assesment period. Atreca anticipates commencing enrollment in the fifth and final cohort (30 mg/kg) shortly, pending review by the Dose Review Committee, and expects to announce initial summary data from the study in July 2021.

Enrollment includes additional patients treated at 3 mg/kg through backfill of the third dose escalation cohort and the initiation of a monotherapy dose expansion cohort, as previously disclosed. Atreca expects to enroll additional cohorts evaluating ATRC-101 in combination with a PD-1 inhibitor and in combination with a chemotherapeutic agent in 2Q 2021 and 2H 2021, respectively.

Pipeline Update        

Atreca has designated a second program, with APN-122597, an antibody derived from the active immune response of a cancer patient, as the program lead. APN-122597 binds to a membrane proximal extracellular epitope of EphA2, a receptor tyrosine kinase (RTK) validated as a known tumor target that is overexpressed in multiple cancers, but with no approved therapies targeting it. A human normal tissue cross-reactivity study showed no reactivity of toxicological significance, and APN-122597 is active in vitro in multiple formats. Atreca expects to provide additional information on APN-122597 and other pipeline assets, including timelines for development, at an R&D Day in 4Q 2021.

“APN-122597 is another example of the power of our discovery approach,” said Dr. Tito Serafini, Atreca founder and Chief Strategy Officer. “While EphA2 is validated as a known and potentially high value target, there are only a limited number of development-stage programs currently targeting EphA2, and no therapies on the market. We believe our antibody is differentiated by its apparent lack of both EphA2 activation and interference with ligand-induced activation, its unique patterns of reactivity with tumor tissue and cells, and its structural features. Furthermore, lead optimization has already yielded improved molecules with an anticipated low level of sequence-based CMC risk.”

IP Update        

In April 2021, the United States Patent and Trademark Office issued a Notice of Allowance for U.S. patent application serial no. 13/261,763 (exclusively licensed to Atreca), covering fundamental aspects of Atreca’s Immune Repertoire Capture® technology (IRC®), which forms a core part of the company’s discovery platform. This patent, once issued, further bolsters our global patent coverage for compositions of matter that are a key output of Atreca’s IRC® technology.

About Atreca, Inc.
Atreca is a biopharmaceutical company developing novel antibody-based immunotherapeutics generated by its differentiated discovery platform. Atreca's platform allows access to an unexplored landscape in oncology through the identification of unique antibody-target pairs generated by the human immune system during an active immune response against tumors. These antibodies provide the basis for first-in-class therapeutic candidates, such as our lead product candidate ATRC-101. A Phase 1b study evaluating ATRC-101 in multiple solid tumor cancers is currently enrolling patients. For more information on Atreca, please visit www.atreca.com.
