NEW YORK, June 4, 2013 /PRNewswire/ -- Attorney Advertising -- Bronstein, Gewirtz & Grossman, LLC is investigating potential claims on behalf of purchasers of the securities of Pluristem Therapeutics, Inc. ("Pluristem" or the "Company") (NasdaqCM: PSTI -News). The investigation focuses on whether the Company and its executives violated federal securities laws. On Tuesday, June 4, 2013, shares of the Pluristem fell $0.47 or 14% during intraday trading after the Company said a mid-stage trial of its experimental muscle pain drug was put on clinical hold by the U.S. Food and Drug Administration due to a serious allergic reaction in a patient. Out of 74 patients enrolled in Pluristem's trials to date, the Company said this was the first incident of a serious allergic reaction. The patient was discharged from the hospital the following day, following the resolution of all her symptoms. Under a clinical hold, the FDA can suspend or delay an ongoing study and ask for information from the company. The FDA will issue a letter within the next 30 days detailing a list of questions and requests for information from Pluristem.
