Thymosin alpha-1 — regulatory status
Authorisation status by jurisdiction, development status, and the distinction between an authorised product and research supply.
§5Regulatory status
§5.1Status by jurisdiction
Table 5. Regulatory status of Thymosin alpha-1 by jurisdiction, as recorded at the assessment date.
| Jurisdiction | Status | Detail |
|---|---|---|
| Italy, China, Japan and more than thirty other countries | Approved | Thymalfasin, for chronic hepatitis B and C, as a vaccine adjuvant, and in some jurisdictions in sepsis and oncology support |
| United States | Not approved | Orphan designation was granted for certain indications; no marketing authorisation |
| European Union | Nationally authorised in some member states | Not centrally authorised |
| Research-use supply | Not approved | Offered by many suppliers |
| Recorded at the assessment date. Regulatory status changes and this table is re-examined at each review. | ||
§5.2Development status
Approved. Holds a marketing authorisation for at least one indication in at least one jurisdiction.
Table 6. Published trials held by the Institute for this compound, by phase.
| Phase | Trials | Identifiers |
|---|---|---|
| Phase 2 | 1 | TA1-VACCINE-ELDERLY |
| Phase 3 | 3 | TA1-HBV-1 · TA1-HCV-1 · TA1-SEPSIS-CN |
§5.3Supply outside authorisation
Material offered by research-chemical suppliers is not manufactured under a marketing authorisation, is not subject to the quality system that governs an authorised product, and is not covered by any pharmacovigilance obligation. The distinction matters for this monograph because every efficacy and safety estimate reproduced in §3 and §4 was obtained using material manufactured under such a system. The Institute records supply considerations separately at §8 and analytical characterisation at §6.[1,2]
