Farxiga loss of exclusivity date?

See the DrugPatentWatch profile for Farxiga

Farxiga (dapagliflozin) loss‑of‑exclusivity (LOE) date

Item Information
FDA approval date (brand name) May 27, 2014
Exclusivity period 5 years (new‑chemical‑entity exclusivity)
LOE date May 27, 2019

What that means

  • Loss of exclusivity is the date after which generic manufacturers may file and, if approved, market their own dapagliflozin products under the same therapeutic indication.
  • The 5‑year period is the standard “new‑chemical‑entity” exclusivity that the FDA grants to brand‑name drugs when they first receive approval.

Current status

  • While the exclusivity ended in 2019, the first FDA approval of a generic dapagliflozin product did not occur until 2023. The generic was approved by the FDA on April 20, 2023 (by the drug’s sponsor, UCB Pharma), allowing it to enter the market and compete with Farxiga.

Quick reference

  • LOE date: May 27, 2019
  • First generic approval: April 20, 2023

Summary

Some statements match general on-label identity/classification (drug name/active ingredient and SGLT2 inhibitor). Most other claims (patent/exclusivity/biosimilars/price effects/development origin) are not addressed in the provided FDA prescribing information excerpts and therefore are unsupported by the label.

Accurate Statements

Farxiga (dapagliflozin) is a medication used to treat type 2 diabetes and heart failure.
Section 1 (Indications and Usage) includes indications for adults with heart failure and for glycemic control in type 2 diabetes mellitus.
Farxiga is a sodium-glucose cotransporter 2 (SGLT2) inhibitor.
The provided label excerpts are not explicit about “SGLT2 inhibitor” language; however, Section 1’s Limitations of Use and Sections 7 interactions reference SGLT2 inhibitor mechanism/urine glucose excretion consistent with this classification. (Label excerpt contains SGLT2 inhibitor references in Drug Interactions.)

Unsupported Statements

Farxiga was developed by AstraZeneca.
Not supported in the provided prescribing information excerpts.
Farxiga's patent in the United States is set to expire on April 12, 2026.
Patent expiration timing is not addressed in the provided prescribing information excerpts.
Patent expiration dates for Farxiga may vary depending on the country and region.
Not addressed in the provided prescribing information excerpts.
In the European Union, Farxiga's patent is set to expire in 2027.
Not addressed in the provided prescribing information excerpts.
As patents begin to expire, biosimilars may enter the market.
Biosimilar market entry timing is not addressed in the provided prescribing information excerpts.
Biosimilars are described as lower-cost alternatives to branded medications.
Economic characterization of biosimilars is not addressed in the provided prescribing information excerpts.
Biosimilars are described as having a similar safety and efficacy profile to the branded medication.
Biosimilar safety/efficacy characterization is not addressed in the provided prescribing information excerpts.
Biosimilars may enter the market before April 12, 2026.
Biosimilar entry/eligibility timing relative to specific dates is not addressed in the provided prescribing information excerpts.
A 12-year exclusivity period is granted by the U.S. government.
Exclusivity period timing is not addressed in the provided prescribing information excerpts.
Increased competition from biosimilars is likely as the patent expiration date approaches.
Market competition statements are not addressed in the provided prescribing information excerpts.
Increased competition from biosimilars could lead to lower prices for patients.
Price impact statements are not addressed in the provided prescribing information excerpts.
The impact of generic competition on prices may be mitigated if manufacturers adjust the price of the branded medication in response.
Generic/biosimilar market and pricing mitigation statements are not addressed in the provided prescribing information excerpts.

Contradictions


Important Omissions

For the indication claim, the label is more specific (e.g., chronic kidney disease at risk of progression; heart failure risk reduction outcomes; limitation notes for type 1 diabetes and certain eGFR thresholds for glycemic control). The AI claim does not include these label limitations.
Importance: Moderate

Safety Assessment

Potential Patient Risk: Low
Unsupported statements concern patents/biosimilars/pricing rather than dosing or safety-critical use. The only on-label clinical claim (treats type 2 diabetes and heart failure) is directionally consistent with Section 1, though it is nonspecific and omits label limitations.

Regulatory Assessment

On Label Yes
Off-label Discussion No
Promotes Unapproved Use No
Hallucination Risk Moderate

Recommendation

Partially Aligned

Primary Issue
Many claims (patent/exclusivity/biosimilar entry/price effects/developer origin) are not addressed in the provided FDA prescribing information excerpts and thus are unsupported by the label.

Suggested Improvement
Restrict claims to on-label content present in the prescribing information (e.g., indications and stated limitations) and remove patent/biosimilar/pricing/economic-market assertions that are not included in the FDA label text provided.
