ATRECA CORPORATE OVERVIEW

Investor Relations

Atreca is a biotechnology company developing novel therapeutics drawn from human immune responses, including effective anti-­cancer immune responses. We are able to measure and analyze the structure of clinically relevant immune responses to identify the antibodies, T cell receptors, and targets that are key to successful treatment outcomes. Atreca’s proprietary Immune Repertoire Capture® technology profiles a patient’s immune response at the single-­cell level at very high throughput essentially without bias or error, enabling the identification and generation of functional human antibodies and TCRs without prior knowledge of antigen. The Company is advancing a pipeline of candidates designed to engage the human immune response in oncology and other indications, thus driving better therapeutic outcomes.
