A Philadelphia judge has struck down the bid to establish a mass tort program for numerous cases claiming the antibiotics Levaquin, Avelox and Cipro led to nerve damage.

Administrative Judge Jacqueline F. Allen last week denied a motion from 32 plaintiffs who had sought to consolidate their claims into a mass tort. She issued her decision in Whitters v. Bayer in a one-paragraph order siding with the drugmakers Bayer Corp. and Johnson & Johnson. The order did not explain Allen’s reasoning.
