AbbVie, Novartis and Bristol Myers Squibb sue Illinois over 340B drug discount law

AbbVie, Novartis and Bristol Myers Squibb each filed separate lawsuits in Illinois this week.

The suits challenge a state law that seeks to regulate how manufacturers participate in the 340B drug discount program.

The filings underscore the pharmaceutical industry's broader resistance to state-level attempts to control 340B pricing.

All three cases were initiated within the past week, suggesting a coordinated legal strategy.
