Light Sciences (now LSO) was founded in 1994 to find and produce a commercially viable light-activated drug product to treat patients with solid tumor cancers. LSO has built a strong development organization with an efficient team overseeing engineering, clinical trials, manufacturing, and regulatory/legal affairs. The company has developed a low-cost, palm-sized, single-use, disposable light-activation unit that is designed for easy use by physicians and to provide tolerable, effective, and repeatable treatments to cancer patients.

LSO completed a $67 million Series A preferred financing in late 2005. A $30 million Series B preferred financing was completed in June 2007.
