Description:

Signature BioScience Inc. was the first biotechnology company based in San Francisco. It was formed in 1998 but closed in 2003 due to lack of funding. Before Signature was dissolved, it had just completed Phase II trials on Digitoxin, which the company was pursuing as an anti-cancer compound. However, the company's core competency was developing biotechnology tools that would be used to identify highly qualified pre-clinical leads.
