Regulatory status
Thymosin alpha-1 does not have an approved drug label. It is classified as an unapproved research compound, and no indications, dosing, or safety information have been established through an approved regulatory review.
What thymosin alpha-1 is
Thymosin alpha-1 is a peptide with the molecular formula C129H215N33O55 and a molecular weight of approximately 3,108.3 daltons (PubChem CID 16130571). Because it lacks an approved label, there is no FDA-sanctioned description of its mechanism, indicated uses, or approved brand names.
Trial footprint
There are 66 registered clinical trials referencing thymosin alpha-1. Sampled studies illustrate the range of conditions under investigation rather than any established use. One phase 2 trial examining an abscopal effect in metastatic colorectal cancer was withdrawn. A phase 3 trial testing recombinant human interferon alpha nasal drops, studied alongside thymosin alpha-1 research contexts, to prevent 2019-nCOV infection in medical staff carries an unknown status. A separate trial evaluating long-term outcomes in sepsis patients after immunotherapy has not yet begun recruiting.
FAQ
