Exai Bio Company Profile

Background

Exai Bio, established in 2021 and headquartered in Palo Alto, California, is a pioneering liquid biopsy company dedicated to transforming cancer diagnostics. The company's mission is to enable early detection, accurate diagnosis, personalized treatment, and ultimately, the cure of cancer. By leveraging proprietary RNA and artificial intelligence (AI)-based technologies, Exai Bio delivers deep clinical insights into cancer biology through non-invasive blood tests.

Key Strategic Focus

Exai Bio's strategic focus centers on developing and commercializing its next-generation liquid biopsy platform. This platform utilizes RNA sequencing to identify orphan non-coding RNAs (oncRNAs), a novel class of small RNA biomarkers abundant in tumors but absent in normal tissues. By integrating these biomarkers with advanced AI and machine learning algorithms, Exai Bio aims to achieve superior sensitivity and specificity in cancer detection. The company targets multiple applications, including early cancer detection, monitoring treatment response, assessing molecular residual disease, and guiding therapy selection.

Financials and Funding

In December 2021, Exai Bio secured a $67.5 million Series A financing round to accelerate the development of its RNA-based liquid biopsy platform. The round was led by Section 32 and Casdin Capital, with participation from Two Sigma Ventures. The capital is intended to advance the company's technology and expand its clinical applications.

Pipeline Development

Exai Bio's liquid biopsy platform has been utilized in multiple studies, notably the I-SPY 2 trial, a neoadjuvant, adaptive clinical trial designed to improve outcomes in individuals with high-risk breast cancer. Initial data demonstrated that oncRNAs were significant predictors of patient outcomes, leading to an expanded collaboration to evaluate oncRNAs as predictive and prognostic biomarkers across multiple therapies.

Technological Platform and Innovation

Exai Bio's platform is distinguished by its focus on oncRNAs, which are actively secreted from living cancer cells and abundant in the blood. These biomarkers offer advantages over circulating tumor DNA (ctDNA)-based tests, including superior sensitivity and specificity, lower cost of goods, and the ability to reveal dynamic changes in tumor biology over time. The integration of proprietary AI and machine learning algorithms enables the identification of cancer-specific patterns, enhancing diagnostic accuracy.
