A federal judge in Florida dismissed large chunks of the litigation alleging heartburn medication Zantac causes cancer, but plaintiffs lawyers insist the “vast majority” of their claims are moving forward.

U.S. District Judge Robin Rosenberg of the Southern District of Florida tossed claims brought under the U.S. Racketeer Influenced and Corrupt Organizations Act, as well as medical monitoring claims, which seek reimbursement for the costs of diagnostic tests that could detect cancer in the future. She also tossed the distributors from the litigation entirely and the pharmacies, such as Rite Aid and CVS, from all personal injury claims, and dismissed claims brought under the innovator liability theory, which holds brand companies liable for the labeling of generic medications.
