Almost all the plaintiffs in 34 federal cases about the blood thinner Eliquis agree with the drugmakers that the actions should be centralized before one judge — now the question is where.

Attorneys for defendants Bristol-Myers Squibb Co. and Pfizer Inc. pushed Thursday to consolidate the cases as multidistrict ligitation in the Southern District of New York. The drug companies both have New York headquarters, and defense attorney Loren Brown of DLA Piper’s New York office told the Judicial Panel on Multidistrict Litigation that witnesses and documents related to the case will come from those headquarters.
