Pacira Pharma pain drug fails late-stage trial Thu Aug 1, 2013 4:24pm EDT (Reuters) - Pacira Pharmaceuticals Inc said its lead drug did not meet the main goal in a late-stage trial of reducing pain for patients undergoing a surgical procedure called posterolateral thoracotomy. Pacira said the company did not meet the main goal of reducing pain scores over 72 hours, compared with a placebo. The results are from a second late-stage study of the drug, Exparel, which is already approved as a single-dose injection to treat postsurgical pain.
