HB 429 Delaware House · 153rd General Assembly (2025-2026)

AN ACT TO AMEND TITLE 18 OF THE DELAWARE CODE RELATING TO THE STEP THERAPY EXCEPTION PROCESS.

Summary
This Act modernizes Delaware law by adding modern medical treatment options biologics or biosimilars to the step therapy exception process. The current law was passed before biosimilars were widely available. Biosimilars are to biologics what generic drugs are to traditional drugs once their exclusivity expires. This revision adds an exclusion to step therapy protocol exceptions for interchangeable biologics and biosimilars.
Issues: ✓ HealthcareSupports HealthcareBill expands access to modern medical treatments (biosimilars) by preventing restrictive step therapy, thereby improving patient care options.95% confidence
