Initial GEN-011 clinical trial data to be presented at AACR

Conference call today at 8:30 a.m. ET

CAMBRIDGE, Mass., March 10, 2022 (GLOBE NEWSWIRE) -- Genocea Biosciences, Inc. (Nasdaq: GNCA), a biopharmaceutical company developing next-generation neoantigen immunotherapies, today provided a business update for the fourth quarter ended December 31, 2021.

GEN-011 TiTAN™ trial update

Genocea is conducting the Phase I/2a TiTAN clinical trial for its lead program GEN-011, a neoantigen-targeted peripheral T cell (NPT) therapy candidate. GEN-011 is comprised only of CD8+ and CD4+ T cells, extracted from the patient’s peripheral blood and specific for ATLAS-prioritized neoantigens. Patients receive either GEN-011 in multiple fractional doses without lymphodepletion and with intermediate doses of IL-2, or as a single dose after lymphodepletion and with intermediate or high doses of IL-2.

Genocea will present clinical, preclinical, and manufacturing data at next month’s American Association for Cancer Research (AACR) Annual Meeting 2022 to be held from April 8-13 in New Orleans. In addition, the company will host an investor call which will span the late-breaking clinical data from the TiTAN clinical trial, results demonstrating success with GEN-011’s PLANET™ manufacturing process, and new preclinical data on Inhibigens™, antigens of pro-tumor immune responses uniquely identifiable by Genocea’s ATLAS™ platform.

“We are excited to present initial data on the first five patients in our TiTAN clinical trial for GEN-011,” said Chip Clark, Genocea’s President and Chief Executive Officer. “We believe these data will begin to solidify the potential for GEN-011 to represent a differentiated autologous T cell therapy for solid tumors through the neoantigen selection capabilities of our ATLAS platform and the reliable expansion of T cells specific to ATLAS-validated neoantigens taken from peripheral blood by the PLANET manufacturing process.”

ATLAS performance
As of March 3, 2022, Genocea has completed screening 23 patient samples with ATLAS in the TiTAN trial. On average in these samples, ATLAS has prioritized 12 neoantigens (range 0-43) and identified 16 Inhibigens (range 1-82) per patient. T cells specific for the prioritized neoantigens (and therefore not the Inhibigens) are expanded in the PLANET process.

PLANET performance
These T cells are grown in PLANET, Genocea’s robust and rapidly scalable cell expansion process. Of the 17 patient samples entering the PLANET manufacturing process, 100% have either successfully yielded a released drug product (14) or are continuing in process (3).
