Evidence Level

Overview

ARA-290 (Cibinetide) is a synthetic 11-amino acid peptide derived from the structure of erythropoietin (EPO) but engineered to activate only the tissue-protective receptor (Innate Repair Receptor) without stimulating red blood cell production. The short version: people usually care about it for neuropathic pain, diabetic neuropathy, tissue repair without erythropoiesis, but the strength of the evidence depends heavily on indication and study type.

ARA-290 (Cibinetide) is a synthetic 11-amino acid peptide derived from the structure of erythropoietin (EPO) but engineered to activate only the tissue-protective receptor (Innate Repair Receptor) without stimulating red blood cell production. This solves a major problem with EPO — it provides the healing and neuroprotective benefits without the dangerous blood thickening side effects.

Developed by Araim Pharmaceuticals, ARA-290 has been through Phase II clinical trials for diabetic neuropathy, sarcoidosis-associated neuropathic pain, and chronic kidney disease. Results showed significant improvements in small nerve fiber density and neuropathic pain scores.

Research Snapshot

What the evidence says

Phase II

ARA-290 currently shows 4 registered trials from ClinicalTrials.gov, 3 PubMed trial publications (2 RCT-tagged), and 23 PubMed references matching the stored source query. Treat PubMed references as literature surface area, not a count of clinical trials.

Known vs uncertain

Known signals

  • 4 registered trials are tracked from ClinicalTrials.gov intervention records.
  • 3 PubMed clinical-trial publications are indexed.
  • 2 PubMed randomized controlled trial publications are indexed.
  • 23 PubMed references are tracked separately from trial counts and can include animal, in-vitro, review, mechanism, or clinical records.

Open questions

  • Evidence strength may vary by indication, route, formulation, and population.
  • Public anecdotes can highlight interest or concern but do not establish clinical efficacy.
  • Regulatory status and compounding access can change independently from the research literature.

Mechanism of Action

ARA-290 selectively activates the Innate Repair Receptor (IRR), a heterodimer of EPO receptor and beta common receptor (CD131).

Key Research Benefits

Tissue protection without red blood cell stimulation (solves EPO safety issue)
Phase II data for diabetic neuropathy — improved nerve fiber density
Studied for neuropathic pain with significant pain score improvements
Anti-inflammatory and anti-apoptotic effects
Researched for sarcoidosis, chronic kidney disease, and wound healing
