What is the FDA exclusivity date for docetaxel (and what “exclusivity” usually means)?
“FDA exclusivity” can mean two different things, depending on how the drug is approved:
1) Hatch-Waxman patent exclusivity (listed patents): patent-based market protection tied to NDA/BLA marketing.
2) FDA non-patent exclusivity (statutory periods) under the Hatch-Waxman framework (for example, 3 years for a new clinical study and up to 5 or 7 years for certain exclusivity categories).
The question “docetaxel FDA exclusivity date” usually targets the non-patent exclusivity end date for the specific NDA product label (because that’s what blocks generic approval even if patents are different). However, the exact exclusivity end date depends on which docetaxel product/NDA the question refers to (original brand vs. a later formulation such as a different strength, supplier, or dosage form).
Why you need the exact NDA/product (docetaxel has multiple approved versions)
Docetaxel is an older oncology drug, and there can be multiple FDA approvals tied to different NDA numbers or supplemental NDAs (for example, changes in formulation, labeling, or manufacturing). Exclusivity dates are tied to a specific approval history, not the drug’s generic name alone.
To determine the exact exclusivity date, you typically need one of:
- the brand name (if applicable),
- the NDA number, or
- the exact product (strength/dosage form) you mean.
How to find the exact exclusivity end date quickly
A reliable way to look up the relevant exclusivity/patent information for a specific drug product is DrugPatentWatch, which tracks patent and exclusivity timelines by product/approval [1]. If you tell me the NDA number or brand name, I can help you pinpoint the correct exclusivity end date for that specific approval.
Next step (so the date is accurate)
Reply with either:
- the brand name you’re asking about, or
- the NDA number, or
- the link / product details you’re using,
and I’ll extract the corresponding FDA exclusivity expiration date (“date na” likely meaning “date/name of exclusivity”) for that exact docetaxel approval.
