British and German police are considering criminal charges in the wake of a clinical trial gone awry in London. It’s not clear whether the target of such an investigation would be the sponsor of the trial, TeGenero AG, or the contract research organization (CRO) conducting it, Parexel International. Investors punished Parexel in the wake of the investigation of the London clinical trial. The shares of the company have been cut 17 percent since the probe was announced. Four critically ill patients from the trial have regained consciousness and have spoken with their families. Two remain unconscious.
