Achaogen and TRIANNI Sign Licensing Agreement for Use of Trianni Transgenic Mouse Platform

San Francisco, CA, and South San Francisco, CA – February 8, 2016 – TRIANNI, Inc. (“TRIANNI”) and Achaogen, Inc. (NASDAQ:AKAO), today announced a licensing agreement for Achaogen’s use of the Trianni Mouse Platform. The Trianni Transgenic Mouse Platform is a human monoclonal antibody discovery platform based on a novel chimeric gene segment design, and featuring extensive variable domain diversity. Achaogen, a clinical-stage biopharmaceutical company developing novel antibacterials to treat multi-drug resistant (MDR) gram-negative infections, plans to leverage the Trianni Platform for the discovery and development of antibodies against several novel targets.

“Achaogen’s goal is to generate monoclonal antibodies to treat multi-drug resistant bacterial infections and we are excited to add the capabilities of the Trianni Mouse to our antibody discovery platform,” commented Lee Swem, Ph.D., Vice President and Head of Research at Achaogen. “We believe that the Trianni Mouse technology will allow us to rapidly realize the diversity of the human immune repertoire, while also speeding up development timelines.”

“We are happy that Achaogen has adopted the Trianni Mouse,” commented Dr. Matthias Wabl, Ph.D., Chairman and CEO of TRIANNI. “With its full repertoire of human immunoglobulin variable regions expressed from chemically synthesized chimeric gene segments, we believe the platform will prove highly productive for Achaogen.”
