Part 5: Policy, Pricing, and the Social Contract

  1. On Price Controls: "This is a program that prevents investors from being able to invest and inventors from being able to invent." — BIO Interview: Foreign Price Controls & Life Science Investments
  2. On the "Chilling Effect": Government-imposed foreign reference pricing and broad price controls have an absolutely chilling effect on the venture capital needed for early-stage science. — BIO Interview: Foreign Price Controls & Life Science Investments
  3. On the Social Contract: The healthcare industry needs a "New Drug Pricing Social Contract" that effectively balances the necessity of innovation with the mandate for patient access. — BIO Interview: Drug Pricing Social Contract & Policy
  4. On Out-of-Pocket Costs: Rather than targeting the innovators with price controls, policymakers should focus on redesigning insurance structures to reduce patient out-of-pocket costs. — BIO Interview: Drug Pricing Social Contract & Policy
  5. On Intellectual Property: Strong intellectual property protections are the bedrock of biomedical innovation, allowing companies to justify decades of rigorous research and development. — Invest Like the Best: The Trillion-Dollar Health Revolution
  6. On Coverage Hurdles: Complex and restrictive insurance coverage structures frequently complicate the commercial path for newly approved, life-saving therapies. — BIO Interview: Drug Pricing Social Contract & Policy
