Press Release: Aquinox Pharmaceuticals completes US $ 14.5 million Series A financing

Aquinox Pharmaceuticals completes US $ 14.5 million Series A financing VANCOUVER, June 12 - Aquinox Pharmaceuticals Inc., a Vancouver-based privately-held pharmaceutical company developing targeted small molecule therapeutics for the treatment of cancer and inflammatory disease, has raised US$14.5 million in a Series A venture capital financing. The financing was led by Ventures West Capital Ltd. and included new investors, Johnson & Johnson Development Corporation (JJDC) and Baker Brothers Investments. Existing investor, BC Advantage Funds, managed by Lions Capital Corp., also participated in the financing. Aquinox was incorporated in 2004 as a spin-off company from the University of British Columbia and the BC Cancer Agency, and based on the research of four founding scientists: Dr. Raymond Andersen, Dr. Gerald Krystal, Dr. Alice Mui and Dr. Christopher Ong. The scientific founders discovered highly selective drugs that target a unique and patented biochemical enzyme called "SHIP" (SH2-containing inositol phosphatase) which regulates the PI3 kinase (PI3K) pathway. The PI3K pathway is essential in regulating cell growth, survival and immune cell activation, and is one of the most studied pathways for the development of new therapeutic agents. SHIP is unique in that it exclusively regulates blood cells and can be harnessed in the treatment of disorders such as multiple myeloma, leukemia, lymphoma, inflammation, allergy and autoimmune diseases while having no, or minimal, effect on non-blood tissues. "The activation or inhibition of SHIP and similar enzymes can support a rich pipeline of potential therapeutic programs in the areas of cancer, autoimmune, inflammatory and allergic diseases," said David J. Main, Chairman, President and CEO of Aquinox Pharmaceuticals Inc. "This significant financing from a strong cross-border syndicate will allow us to advance the development of our lead product candidate into clinical studies in 2008 for an oncology indication while advancing another pre-clinical drug candidate in the area of inflammatory disease." Concurrently with the Series A financing, Mr. Chris Laird, Vice President at Ventures West and Dr. Asish Xavier, Principal at JJDC, will join existing independent directors, Dr. Kevin Leslie and Mr. Kenneth Galbraith on the Board of Directors of Aquinox. "Aquinox has assembled a world-class scientific and management team," commented Chris Laird. "It has established a strong intellectual property position covering SHIP, closely related enzymes and a number of drug candidates that they are advancing through further development. They are poised to become a leader in this field."
