Summary
Changes the rules so that once a drug is approved as a 'biosimilar,' it is automatically considered 'interchangeable' with the original, more expensive drug.
What problem does this solve?
Currently, biosimilar drugs must pass a second, costly approval step to be considered 'interchangeable' at the pharmacy, delaying access to cheaper options. This bill removes that extra step, allowing any approved biosimilar to be automatically substituted for its brand-name version.
What does this bill do?
Automatic interchangeability for biosimilars
Makes any biological drug approved as a 'biosimilar' automatically considered 'interchangeable' with the original brand-name drug. This removes the need for a separate, second approval step.
Establishes a transition period
Sets a 'transition date' 60 days after the bill becomes law. Biosimilars approved before this date become interchangeable on this date, while those approved after are interchangeable immediately.

Section:
Sec. 2(a)(5)
Header:
Transition with respect to preserving first interchangeability exclusivity
Preserves existing market exclusivity
Ensures that any biosimilar drug that already earned an 'interchangeable' status under the old rules keeps its period of market exclusivity without competition.
Requires updated FDA guidance
Directs the government to update or cancel existing guidance documents for drug makers to match the new rules within 18 months of the bill becoming law.
Who does this affect?
- Patients using biologic medicines
- Pharmaceutical companies
- Pharmacists and doctors
What is the real world impact?
•
Lowers prescription drug costs
Simplifies the approval process for biosimilar drugs, which are cheaper versions of complex medicines. This increases competition and can lead to lower prices for patients and insurance providers.
•
Reduces regulatory burdens
Eliminates what some see as an unnecessary and expensive step for drug makers to prove their biosimilar product is interchangeable. This saves time and money for companies developing these lower-cost alternatives.
When does this start?
The bill's changes take effect based on several deadlines after it becomes law.
Transition Date for Interchangeability
60 days after the bill becomes law, all previously approved biosimilars will be considered interchangeable.
Guidance Document Updates
The Secretary must update all related guidance documents for drug makers no later than 18 months after the bill becomes law.
