Definition
Orphan Drug Exclusivity is a 7-year period of market protection granted for drugs approved to treat rare diseases (affecting fewer than 200,000 Americans). During this period, FDA generally cannot approve the same drug for the same indication from another sponsor.
How Orphan Exclusivity Works
Upon approval of an orphan drug, the sponsor receives 7-year exclusivity for that specific rare disease indication. The protection is narrower than NCE exclusivity but longer.
Key Features
- 7 years from approval date
- Specific to the approved indication
- Blocks same drug for same indication
- Can be overcome by clinical superiority
- Independent of patent protection
Orphan Exclusivity Scope
| Blocked | Not Blocked |
|---|---|
| Same drug, same indication | Different drug, same indication |
| Same drug, same rare disease | Same drug, different indication |
| Generic or biosimilar of orphan | Clinically superior version |
