ARA-290 Dosage Chart & Schedule

ARA-290 (cibinetide) is an 11-amino-acid peptide modeled on the helix-B region of erythropoietin. It selectively engages the innate repair receptor without stimulating red-cell production, and has been studied for neuropathic pain and tissue protection, notably in sarcoidosis-related small-fiber neuropathy. It is investigational.

The short answer

In small clinical studies of small-fiber neuropathy, cibinetide (ARA-290) has most often been given as about 4 mg subcutaneously once daily for roughly 28 days. It is investigational and not an approved drug.

Selective repair receptor, not erythropoiesis

  • ARA-290 engages the innate repair receptor (EPOR/CD131 heteromer) without stimulating red-cell production, unlike full-length erythropoietin.
  • Plasma half-life is only minutes, but the tissue-protective signaling it triggers is studied over a longer window, which supports once-daily dosing.

From vial to injection in 6 steps

1

Wipe both vial tops

Swab the peptide vial and the bacteriostatic-water vial with fresh alcohol and let them dry.

2

Draw the water

Pull the planned amount of bacteriostatic water (2 mL) into the syringe.

3

Add it slowly

Run the water down the inside wall of the vial — don't blast the powder. Swirl gently; never shake.

4

Let it dissolve

Wait until the solution is fully clear, then refrigerate the vial.

5

Draw your dose

Pull the calculated units on a U-100 insulin syringe.

6

Store between uses

Keep the reconstituted vial refrigerated and use within its stable window.

Handling & storage

  • A 4 mg vial reconstituted with 2 mL of bacteriostatic water gives 2 mg/mL; a 2 mg vial with 1 mL gives the same concentration.
  • At 2 mg/mL, a 4 mg dose is 2 mL and a 1 mg dose is 0.5 mL (50 units on a U-100 syringe).
  • Keep the reconstituted vial refrigerated and inspect for clarity before use.
  • Investigational compound; not approved for treating any condition.

ARA-290 dosing FAQ

What ARA-290 dose is used in research?

Clinical studies in small-fiber neuropathy most often used about 4 mg subcutaneously once daily for roughly 28 days.

Why is it dosed daily if the half-life is only minutes?

The peptide clears quickly, but it acts as a trigger for downstream tissue-protective signaling that outlasts the molecule, so once-daily dosing is the common trial pattern.

How is a 4 mg vial reconstituted?

Adding 2 mL of bacteriostatic water yields 2 mg/mL, which conveniently makes the whole 2 mL a single 4 mg dose.

Is ARA-290 approved?

No. It is investigational; the dosing above reflects study protocols, not a treatment recommendation.
