Attorney Advertising--Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of the securities of Columbia Laboratories, Inc. (“Columbia Laboratories” or the “Company”) (Nasdaq: CBRX), concerning whether the company and certain of its officers and directors have violated federal securities laws. On January 20, 2012, Columbia Laboratories confirmed that the Advisory Committee for Reproductive Health Drugs of the U.S. Food and Drug Administration (FDA) did not recommend approval of progesterone vaginal gel 8% for the reduction of risk of preterm birth in women with short uterine cervical length at the mid-trimester of pregnancy. The investigation concerns whether statements made by the Company and certain of its officers regarding the safety and effectiveness of the Company’s progesterone gel product Prochieve were materially false and misleading. On December 14, 2011, the Company issued a press release highlighting the purported results of clinical trials that showed that Prochieve “significantly reduces the risk of preterm birth and neonatal morbidity.” On this news, Columbia Laboratories’ stock increased in price significantly. On January 17, 2012, however, the FDA released documents including trial data that indicates Prochieve is not effective. As a result, Columbia Laboratories’ stock price declined over 50%, to $1.10, well below where it traded before the December 14, 2011 announcement.
