Was Vitravene (fomivirsen) discontinued in the Orange Book?
Vitravene (fomivirsen) is no longer marketed, and it has been discontinued. As a result, the product would not be actively marketed under the current FDA “Orange Book” listings, which track approved prescription drug products and their related patent/exclusivity status. The Orange Book is also a federal database for approved applications (NDA/ANDA) and listed patents, so discontinued products typically show no current marketing.
How do I confirm “discontinued” using the Orange Book?
To verify the status you’ll usually look up:
- The product name (“Vitravene” / “fomivirsen”) in the Orange Book
- The NDA entry associated with Vitravene
- Any “discontinued”/“withdrawn”/marketing status signals associated with that listing (the Orange Book contains fields that indicate whether a product is no longer marketed)
If you want, tell me the exact spelling you’re searching (Vitravene vs. fomivirsen) and any NDA number you see, and I can help you interpret what the Orange Book entry means.
What happens to Orange Book patents once a drug is discontinued?
Discontinuation doesn’t automatically erase the Orange Book historical listing for the NDA and associated patent/exclusivity entries. The Orange Book is still used for regulatory and patent history, but the practical effect is that there’s no active commercial product being sold, so there’s no ongoing FDA-regulated product supply tied to that specific brand name.
Why was Vitravene discontinued?
Vitravene was used for cytomegalovirus (CMV) retinitis. It was later discontinued because other CMV treatment options became standard of care, reducing demand for the intravitreal therapy.
Are there generic or alternative versions?
Because Vitravene is a discontinued ophthalmic drug product, you generally won’t find a market-available generic as you would for an actively marketed small-molecule prescription drug. The most relevant “alternatives” are other CMV treatments used for CMV retinitis rather than a bioequivalent version of Vitravene.
