Exosome Diagnostics Scores $27 Million To Launch Prostate Lab Test

Exosome Diagnostics Raises $27 Million in Series B Financing

NEW YORK, March 11, 2014 /PRNewswire/ -- Exosome Diagnostics today announced the initial close of its Series B financing round with the raising of $27 million. Proceeds will be used to advance development of the Company's proprietary platform technology and commercial programs for non-invasive, fluid-based molecular diagnostics in oncology, neurodegenerative diseases and other clinical areas.

Key Points:

• Co-leading the financing were new investors QIAGEN and Arcus Ventures
• New participating investors included Tiger Partners L.P. (an investment vehicle managed by Julian H. Robertson, Jr.), CD Ventures and Monashee Capital
• Existing participating investors included NGN Capital and Forbion Capital Partners
• Steven Soignet, M.D., general partner at Arcus Ventures and former faculty member at Memorial Sloan Kettering Cancer Center, to join Exosome's Board of Directors
• Use of proceeds will include:

1. Launch of the first clinical diagnostic product in the U.S. planned for 2014; EXO106 is a diagnostic test using a non-invasive urine sample which could potentially reduce the number of unnecessary prostate biopsies in patients with an elevated PSA
2. Development under an expanded collaboration with QIAGEN of a blood-based diagnostic test measuring an actionable mutation in non-small cell lung cancer; EXO501 is expected to provide repeated, non-invasive assessment of tumor mutation status
3. Development of a blood-based, multi-gene clinically actionable biomarker panel for use in oncology applications; EXO1000 expected to measure key gene mutations and gene expression levels routinely used in oncology
4. Global launch of exoRNeasy® research kits for RNA extraction from blood serum/plasma targeted for Q2 2014; exoRNeasy® will carry the QIAGEN and Exosome Diagnostics brand names
5. Continued research and development of the Exosome Diagnostics proprietary technology platform

• Leerink Swann served as financial advisor and placement agent to Exosome Diagnostics in connection with the Series B private placement
