Head-to-head comparison of ARA-290 and Vilon — mechanism, dosing, side effects, legal status, and pricing.
ARA-290 (Cibinetide) is a synthetic 11-amino-acid peptide derived from the helix-B surface of erythropoietin (EPO), developed by Araim Pharmaceuticals. It selectively activates the innate repair receptor (IRR) for anti-inflammatory, tissue-protective, and neuroprotective signaling without stimulating erythropoiesis. ARA-290 is not FDA-approved; it has received FDA Fast Track and Orphan Drug designations for sarcoidosis-associated small fiber neuropathy and remains in clinical development as of April 2026.
Vilon is a synthetic dipeptide (Lys-Glu / KE) from the Khavinson bioregulator series, originally derived from thymus extracts and studied in Russian preclinical models as an immunomodulator and geroprotector. Not FDA-approved; all published evidence originates from a single research group.

Dahan et al. (Molecular Medicine, 2013, PMID 24136731) conducted a blinded placebo-controlled trial of 28 days of subcutaneous ARA 290 in sarcoidosis patients with documented small nerve fiber loss; treatment improved neuropathic symptoms, increased corneal nerve fiber density on confocal microscopy, altered thermal thresholds, and improved 6-minute walk distance. Brines et al. (Molecular Medicine, 2015, PMID 25387363) reported a placebo-controlled trial of 4 mg daily SubQ ARA 290 for 28 days in type 2 diabetes: the active arm showed improvements in HbA1c, lipid profile, and PainDetect neuropathic symptom scores, with recovery of intraepidermal nerve fiber measurements versus no change on placebo. Heij et al. (2012) and additional Phase 2 work have supported the tissue-protective signal. ARA-290 has not advanced to Phase 3 registration trials and is not FDA-approved.
Key references
Evidence is limited to Khavinson-group preclinical work. Khavinson & Anisimov (Dokl Biol Sci, 2000; PMID 10944717) reported that Vilon (L-Lys-L-Glu) inhibited spontaneous tumor growth and extended lifespan in CBA mice. A small Russian report on Vilon as an adjuvant in elderly colorectal-cancer patients (Kuznik et al., 2005; PMID 16075684) is non-randomized and unreplicated. No Western-framework clinical trials, pharmacokinetic, or dose-response studies have been published.
ARA-290 (Recovery) and Vilon (Immune) are in different categories and target different biological pathways. This is a common pattern in multi-compound research protocols. Researchers should monitor the biomarkers from both profiles and watch for interactions listed in each compound’s contraindications. Consult a licensed healthcare provider before combining any research compounds.
