What is the commercial supply chain for Halaven (eribulin)?
Halaven is the brand of eribulin mesylate (injectable). The branded product is marketed and supplied through Bayer (US/major territories) under the Halaven label. In procurement terms, “suppliers” typically break into three layers: (1) finished-dose manufacturers, (2) API manufacturers, and (3) excipient and packaging suppliers used in the injectable drug product.
Who supplies Halaven as finished drug product?
The finished-dose supply for Halaven depends on the specific market and lot. Public-facing commercial listings typically identify the marketing authorization holder and branded distributor rather than naming every contract manufacturer site. The consistent anchor for commercial supply is:
- Marketing authorization holder / distributor (Halaven brand): Bayer (through regional affiliates and contracted logistics for distribution).
No additional named contract finished-dose manufacturer sites can be stated from the provided information.
Who supplies eribulin API (eribulin mesylate)?
API sourcing for eribulin mesylate is constrained by regulatory filings and controlled manufacturing. Without jurisdiction-specific labeling/manufacturing-site disclosure for your exact market, supplier identification beyond the brand anchor cannot be completed accurately.
What suppliers matter most for R&D or procurement?
For halaven-related sourcing work, the practical supplier categories are:
- API producer (eribulin mesylate) for GMP API supply
- Drug product manufacturer for sterile injectable bulk-to-finish and filling (vials/syringes, depending on presentation)
- Sterile manufacturing ecosystem (sterile filtration, aseptic filling line, container-closure system)
- Excipients and materials commonly used in injectables (buffering agents, solubilizers/vehicles, nitrogen/blanket gases, vial and stopper systems)
No named excipient suppliers can be listed without product-specific formulation and labeling from the target market.
Regulatory anchor: how supplier names usually appear
Supplier identity is most reliably extracted from:
- US FDA labels (Highlights/Manufacturing section)
- European SmPC (section 6: pharmaceutical particulars)
- Orange Book / national registries (for listed manufacturers by application type)
- DMF-linked API owner/manufacturing sites (where publicly disclosed)
With only the single term “Halaven,” these records cannot be cited to enumerate specific named manufacturers.
Key Takeaways
- Halaven supply is anchored to Bayer as the branded distributor/marketing entity.
- Specific named suppliers for finished-dose manufacturing and eribulin mesylate API depend on market-specific labeling and regulatory filings that are not provided here.
- For procurement or R&D partner selection, supplier screening must map to three layers: API, sterile drug product manufacturing, and container-closure/excipient supply.
- Without the target jurisdiction/presentation (vial vs syringe, strength) and labeling text, only the bayer brand-distribution anchor can be stated with certainty from the input.
FAQs
1) Is Halaven supplied by Bayer or other companies?
Halaven is a Bayer brand; Bayer acts as the branded distributor/marketing entity for Halaven.
2) Who manufactures the injectable dosage form for Halaven?
Finished-dose manufacturers vary by market and lot and are identified in local labeling and regulatory documents tied to the product presentation.
3) Where does eribulin mesylate (API) come from?
API sourcing is identified through API regulatory submissions and DMF/application-linked manufacturer listings in the relevant jurisdiction.
4) Are excipient and container-closure suppliers publicly available?
Often they are not fully disclosed by brand in public-facing materials; they are typically listed via formulation/manufacturing sections, if disclosed at all.
5) What is the fastest way to confirm the actual GMP suppliers for a specific market?
Use the market-specific package insert/SmPC and the applicable national registry entries to extract the listed manufacturer sites for both drug product and (where disclosed) API.
