Securities fraud class action lawsuits against life sciences companies climbed 56 percent last year to 25 lawsuits filed, compared with 16 cases in 2006, according to a new Dechert survey.

The June 2008 Dechert “Survey of Securities Fraud Class Actions Brought Against Life Sciences Companies” also noted that the largest and smallest companies are the most likely to be sued, with large companies increasingly likely to face such lawsuits.
