Overview

• Texas Attorney General Ken Paxton has filed a lawsuit against major insulin manufacturers Eli Lilly, Novo Nordisk, and Sanofi.
• The lawsuit also targets pharmacy benefit managers (PBMs) such as CVS' Caremark, Cigna's Express Scripts, and UnitedHealth's OptumRx.
• Paxton alleges that insulin prices were artificially inflated through a conspiracy between drug manufacturers and PBMs.
• Insulin manufacturers reportedly paid PBMs for preferential treatment, leading to higher list prices and exclusion of cheaper alternatives.
• The lawsuit follows a similar action by the Federal Trade Commission against PBMs but expands the focus to include drug manufacturers.
