Enfuvirtide (Fuzeon) vs Pegvisomant (Somavert)

An educational, source-based comparison of Enfuvirtide (Fuzeon) and Pegvisomant (Somavert) — how each peptide works, what it's researched for, and what to know before going deeper.

Fusion Inhibitor · Antiviral
Enfuvirtide (Fuzeon)

First-in-class HIV fusion inhibitor peptide.

Mechanism

36-amino-acid peptide that binds the gp41 subunit of HIV-1 envelope, blocking the conformational change required for viral-host membrane fusion and cell entry.

Research areas
  • Treatment-experienced HIV-1 infection
Considerations
  • FDA-approved.
  • Injection-site reactions nearly universal.

GH Receptor Antagonist · Endocrine
Pegvisomant (Somavert)

Pegylated GH receptor antagonist for acromegaly.

Mechanism

Genetically engineered analog of human GH with site-directed mutations blocking functional dimerization of the GH receptor; pegylation extends half-life. Lowers IGF-1 without lowering GH.

Research areas
  • Acromegaly inadequately controlled by surgery, radiation, or somatostatin analogs
Considerations
  • FDA-approved.
  • Monitor LFTs; tumor monitoring via MRI required.
  • Lipohypertrophy at injection sites.
