In February 2017 the U.S. Judicial Panel on Multidistrict Litigation denied motion to combine 39 federal lawsuits against various PPI manufacturers into a single MDL. But Seeing the number of cases being filed increases, the panel later reconsidered and officially formed MDL 2789 (PROTON-PUMP INHIBITOR PRODUCTS LIABILITY LITIGATION (NO. II)) in August 2017. admin In 2015, AstraZeneca settled a lawsuit for allegedly participating in a kickback scheme. The Proton-Pump MDL 2789 lawsuits are being adjudicated upon by Judge Claire Cecchi and Judge Mark Falk in the United States District Court of New Jersey.
