What FDA's records say (September 2026 data)
- Trulicity is licensed as a biologic under BLA 125469; the Purple Book lists its 0.75, 1.5, 3 and 4.5 mg autoinjectors as prescription products.[1]
- A biosimilar approval can take effect after the 12-year exclusivity period that follows first licensure. FDA has not listed a first-licensure or exclusivity date for Trulicity.[2]
- Only an interchangeable biosimilar may be swapped in at the pharmacy without your prescriber, and state pharmacy law still applies.[3]
- Patent lists that Lilly gives a biosimilar applicant must reach FDA within 30 days and are published on the Purple Book patent-list page.[4]
Records to recheck every few months
- Purple Book product search for "dulaglutide": any row from a company other than Eli Lilly, marked 351(k)
- That row's licence type: biosimilar, or interchangeable biosimilar
- Purple Book patent-list page: whether Trulicity now appears
- Your plan's formulary: whether a dulaglutide biosimilar is listed, and at what tier
Questions for your pharmacist, prescriber or plan
- Is there a GLP-1 on my formulary that would cost me less than Trulicity this year?
- Am I eligible for the Trulicity Savings Card or a state pharmaceutical assistance program?
- If a dulaglutide biosimilar is licensed, is it interchangeable, and does this state allow pharmacy substitution?
- Would a biosimilar come in a different pen, and who would show me how to use it?
- Would switching to a biosimilar need a new prior authorization?
