ARA-290

Early clinicalErythropoietin derived peptide

Also published as Cibinetide

An eleven residue peptide taken from the helix B region of erythropoietin. It engages the innate repair receptor, the tissue protective side of EPO signalling, without the erythropoietic activity that raises haematocrit.

Where it came from

Developed by Araim Pharmaceuticals following work separating EPO's tissue protective signalling from its haematopoietic signalling.

What the literature examines

  • Innate repair receptor signalling, distinct from the classical EPO receptor
  • Small fibre neuropathy in sarcoidosis, in randomised Phase 2 trials
  • Corneal nerve fibre density as a measurable endpoint
  • Neuropathic pain and diabetic neuropathy models

State of the evidence

Furthest it has gotEarly clinical

Randomised, placebo controlled Phase 2 human trials with published results, including patient reported and corneal nerve endpoints.

What a buyer should know

The Phase 2 results were positive on patient reported outcomes and less clear on some objective measures, and the trials were small. It never progressed to registration.

Handling and stability

Lyophilised, water soluble, cold chain.
