Who supplies ONTRALFY (fostemsavir) in the US?
Brand sponsor supply accountability for the U.S. market sits with Viiv Healthcare. ONTRALFY distribution in the U.S. is executed through Viiv’s commercial network and downstream wholesalers/pharmacies rather than through separately disclosed “third-party suppliers” in public product listings.
Who is the marketing authorization holder?

What suppliers typically appear in public FDA records?
For small-molecule oral products, the most reliable public “supplier” signal is usually:
- Drug substance and drug product manufacturing sites listed on FDA approvals
- Current Good Manufacturing Practice (cGMP) manufacturing information tied to application ownership and labeling
- Orange Book manufacturing/distribution records where available
Those data points are not available in the material provided here.
Which companies manufacture the active ingredient and finished dosage form for ONTRALFY?
No specific drug substance or finished dosage form manufacturers for ONTRALFY can be stated from the provided information.
What manufacturing disclosures usually support “supplier” claims?
- FDA Chemistry Manufacturing and Controls (CMC) sections tied to the NDA

Does ONTRALFY have multiple suppliers or a single-source supply chain?

No ONTRALFY-specific comparative sourcing analysis can be completed without identifying its actual contract manufacturers.

No ONTRALFY-specific supply risk assessment is possible without:
- Historical shortage/recall notices naming sites
- Batch failure reports
- FDA inspection outcomes

Those inputs are not provided.
What substitute sourcing options exist if ONTRALFY’s supplier has capacity constraints?
Substitute sourcing in a regulated context requires either:

No authorized alternative suppliers or ANDA-based substitutes can be identified from the provided information.
