Williams & Connolly Secures Victory on Behalf of Pfizer in Zantac Products Liability Litigation

December 2022

Joe Petrosinelli, Jess Rydstrom, and their team at Williams & Connolly secured a complete victory on behalf of Pfizer in the closely-watched products liability MDL concerning the antacid medication Zantac®. Together, Williams & Connolly and counsel for its co-defendants argued and won a major Daubert and summary judgment ruling in the Southern District of Florida in the litigation, which has effectively ended one of the largest personal injury MDLs ever. At the time of the ruling, this massive MDL included approximately 50,000 claims against multiple pharmaceutical Defendants, alleging that the use of Zantac causes five different cancers. On Tuesday, December 6, 2022, after multiple days of hearings, the MDL judge granted Defendants’ Daubert motions on general causation in their entirety, finding in a 341-page ruling that “no scientist outside this litigation” has concluded that the medication causes cancer. The MDL court therefore granted summary judgment in favor of Defendants on all claims. The Wall Street Journal reported last week that the ruling was “a debunking for the ages.” 

The victory has been covered by media worldwide, including The Wall Street Journal, Financial Times, and Bloomberg.

The Williams & Connolly team included Joe Petrosinelli, Jessica Rydstrom, Elaine Horn, Paul Boehm, Angela Pyo, Annie Showalter, Hope Daily, and Emma Nino.
