ARA-290: Nerve Repair Peptide
Regeneration vs degeneration — where this fits
The body is always doing two things at once: breaking down (degeneration) and building back (regeneration). A condition persists when breakdown outruns repair. Most drugs used for symptoms suppress a signal (pain, acid, anxiety, inflammation) without fixing the tissue that caused the signal. Peptides in this ledger are studied for repair pathways: new blood vessels, repair-cell migration, nerve regrowth, gut lining, neural connections. This article maps one compound through that frame — what it is, how it is proposed to work, what evidence exists, and what people report.
This topic: ARA-290 is studied for nerve repair — especially small-fiber and neuropathy models. Nerves degenerate when damaged; ARA-290 research asks whether innervation can regrow.
What it is
Hash-chained sources verify integrity, not clinical truth. Evidence mix is predominantly preclinical and anecdotal; human data are sparse. No dosing, protocol, or treatment recommendations — catalogue only. ARA-290 is an 11-amino-acid peptide engineered from erythropoietin that selectively activates the innate repair receptor (IRR).
How it works
Step logic:
- Hash-chained sources verify integrity, not clinical truth. Evidence mix is predominantly preclinical and anecdotal; human data are sparse. No dosing, protocol, or treatment recommendations — catalogue only.
- ARA-290 is an 11-amino-acid peptide engineered from erythropoietin that selectively activates the innate repair receptor (IRR).
- In phase 2 trials, ARA-290 reduced neuropathic symptoms and improved quality of life in sarcoidosis small fiber neuropathy patients.
- ARA-290 treatment increased corneal nerve fiber density in sarcoidosis patients with initial reductions.
- In rodent sciatic and spared nerve injury models, ARA-290 reduced allodynia in a β-common receptor-dependent manner.
- 2016 review on ARA290 targeting IRR for neuropathy treatment in sarcoidosis and T2D patients.
- 2025 PubMed abstract on ARA290 inhibiting NLRP3 inflammasome post-sciatic nerve injury for repair.
- 2024 PubMed study on ARA290's neuroprotective effects in cerebral ischemia via beta common receptor, no erythropoiesis.
Why it would work (logic chain)
- IF Hash-chained sources verify integrity, not clinical truth. Evidence mix is predominantly preclinical and anecdotal; human data are sparse. No dosing, protocol, or treatment recommendations — catalogue only. THEN that is one proposed link in a repair/regeneration pathway (not yet proven end-to-end in humans unless a human claim says so).
- IF ARA-290 is an 11-amino-acid peptide engineered from erythropoietin that selectively activates the innate repair receptor (IRR). THEN that is one proposed link in a repair/regeneration pathway (not yet proven end-to-end in humans unless a human claim says so).
- IF In phase 2 trials, ARA-290 reduced neuropathic symptoms and improved quality of life in sarcoidosis small fiber neuropathy patients. THEN that is one proposed link in a repair/regeneration pathway (not yet proven end-to-end in humans unless a human claim says so).
- IF ARA-290 treatment increased corneal nerve fiber density in sarcoidosis patients with initial reductions. THEN that is one proposed link in a repair/regeneration pathway (not yet proven end-to-end in humans unless a human claim says so).
- IF In rodent sciatic and spared nerve injury models, ARA-290 reduced allodynia in a β-common receptor-dependent manner. THEN that is one proposed link in a repair/regeneration pathway (not yet proven end-to-end in humans unless a human claim says so).
- IF 2016 review on ARA290 targeting IRR for neuropathy treatment in sarcoidosis and T2D patients. THEN that is one proposed link in a repair/regeneration pathway (not yet proven end-to-end in humans unless a human claim says so).

How many people take it
There is no reliable global count of how many people take this compound. That number is not in this ledger.
What we can count from this ledger:
- 47 anecdote source(s) (posts, threads, comments)
- 45 anecdote-tier claim(s) derived from them
Logic: 47 online report(s) are catalogued here. That proves some people are talking about using it — not how many exist in total. Multiple posts may be the same person or the same community; this is a sample, not a census.
Evidence inventory
This is a count of what is in this ledger — not a claim about all research worldwide.

Quantified confidence (this ledger): 0.95 / 1.00 — moderate — human claims present in ledger
Formula: human claims×0.12 + preclinical×0.04 + anecdote×0.015 + studies (capped). This is not clinical certainty — it measures how much graded evidence is catalogued here.

What we do not know
- There is a lack of data on the long-term effects of ARA-290 on nerve repair and neuropathic symptoms.
Safety and limits
- Hash-chained sources verify integrity, not clinical truth. Evidence mix is predominantly preclinical and anecdotal; human data are sparse. No dosing, protocol, or treatment recommendations — catalogue only.
