Light Sciences Pulls IPO

Light Sciences Oncology Inc., a Snoqualmie, Wash.-based developer of light-activated treatments for solid tumors, has withdrawn its IPO registration, citing “unfavorable market conditions.” The company had planned to offer 5.25 million common shares at between $14 and $16 per share, with Wachovia Securities and Cowen & Co. serving as lead underwriters.


The company has raised nearly $99 million in VC funding since 2005, from firms like Essex Woodlands Health Ventures, Scandinavian Life Science Venture, Novo AS, New Science Ventures, China Industrial Development Bank and Johnson & Johnson Development Corp.
