ARA-290

Cibinetide / Helix B Surface Peptide

ARA-290 (cibinetide) is an 11- peptide derived from the helix B domain of erythropoietin. It engages the innate-repair (a heterodimer of EPO-R and β common receptor) without stimulating erythropoiesis. Phase II clinical evidence exists in small-fibre neuropathy contexts; it is investigational at the time of writing.

handling notes

01

Mechanism of action

ARA-290 binds the innate-repair (a heterodimer of EPO-R and the β common receptor) found on inflammatory and injured tissue. This selective targeting is associated with tissue-protective and anti-inflammatory effects without stimulating red-blood-cell production.

02

Research applications

  • Small-fibre neuropathy clinical research (sarcoidosis, diabetes)
  • Inflammation and tissue-protection research
  • Innate-repair pharmacology
  • Transplantation and islet-protection research

Evidence caveats

  • ARA-290 is investigational. Primary published evidence is from small Phase II trials and preclinical models.
  • Subsequent late-phase clinical development has been limited; long-term safety and efficacy in humans have not been established in broad peer-reviewed databases.

Storage and handling

Trial material follows the clinical trial protocol cold-chain. Research-grade material must be stored under controlled laboratory conditions per protocol.

  • Trial material follows the clinical trial protocol cold-chain.
  • Research-grade material requires controlled laboratory storage and batch traceability.
  • Investigational — not for unsupervised use.
