The Rosen Law Firm, a global investor rights law firm, announces it is investigating potential securities claims on behalf of investors of Sunesis Pharmaceuticals, Inc. (NASDAQ:SNSS) resulting from allegations that Sunesis Pharmaceuticals may have issued materially misleading business information to the investing public.

On July 23, 2015, Sunesis Pharmaceuticals disclosed that the Food and Drug Administration would not support the filing of a New Drug Application for its proposed leukemia treatment—vosaroxin—because it did not reach statistical significance on the protocol-defined primary analysis of overall survival.
