Cibinetide
An 11 amino acid peptide derived from erythropoietin that calms inflammation without raising red blood cells.
Effects studied or claimed
What it is used or promoted for, and where each effect has actually been seen
- Small fiber neuropathy in sarcoidosisSmall human studies
- Neuropathic pain in diabetesSmall human studies
How it is thought to work
Cibinetide activates the innate repair receptor, a combination of the erythropoietin and beta common receptors, promoting nerve and tissue repair.
What the evidence shows
Small phase 2 trials reported improved nerve fiber density and symptom scores. Larger trials are needed.
Safety and unknowns
Injection site reactions and mild adverse effects were reported.
