Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.

What it is

Enfuvirtide, also known as T-20 and sold as Fuzeon, is a synthetic 36 amino acid peptide derived from a region of the HIV-1 gp41 envelope protein. It is thought to act by binding gp41 and blocking the structural change the virus needs to fuse with and enter human immune cells.

What the evidence shows

Automatic summaryHuman trials

Enfuvirtide is approved for the treatment of HIV-1 infection in combination with other antiretroviral drugs, mainly in treatment-experienced patients. Its antiviral effect is supported by registered human trials up to Phase 4 and a large published literature, though the public FDA database check used here did not confirm the approval record directly.
