Ara-290 (16 mg vial)

Once-daily subcutaneous protocol for innate repair receptor and neuropathy research.

Ara-290 (cibinetide) is an 11 amino acid non-erythropoietic peptide derived from erythropoietin's helix-B domain. It selectively activates the innate repair receptor (IRR), an EPOR/CD131 heterodimer, to promote anti-inflammatory and tissue-protective effects without stimulating red blood cell production. Clinical trials have demonstrated benefits for diabetic neuropathy and sarcoidosis-related small-fiber neuropathy.

Protocol Overview

Concise summary of the regimen.

GoalSupport tissue protection, anti-inflammatory signaling, and neuropathic symptom management via IRR activation.
ScheduleDaily subcutaneous injections for 4 to 8 weeks (clinical trials used 28-day protocols; extension to 8 to 16 weeks based on individual response).
Dose Range2 to 4 mg daily; 4 mg is the established target dose.
Reconstitution1.6 mL per 16 mg vial (10 mg/mL).
StorageLyophilized refrigerated or frozen; reconstituted refrigerated up to 28 days.

Dosing & Reconstitution

WEEKDAILY DOSEUNITS PER INJECTION
Week 12 mg (2,000 mcg)20 units (0.20 mL)
Weeks 2 to 8 (or up to 16)4 mg (4,000 mcg)40 units (0.40 mL)

Frequency: Inject once daily subcutaneously. Clinical studies used 4 mg/day as the target therapeutic dose, with no additional benefit observed at 8 mg. Starting at 2 mg for the first week allows assessment of individual tolerance before reaching the maintenance dose.

Reconstitution Steps

  1. Draw 1.6 mL bacteriostatic water with a sterile syringe.
  2. Inject slowly down the vial wall; avoid foaming.
  3. Gently swirl or roll until fully dissolved (do not shake vigorously).
  4. Label with reconstitution date and refrigerate at 2 to 8 °C, protected from light. At 10 mg/mL, 1 unit = 0.01 mL = 80 mcg on a U-100 insulin syringe.

Storage Instructions

Proper storage preserves peptide quality.

  • Lyophilized: refrigerate at 2 to 8 °C for up to 2 years; freeze at -20 °C for extended storage up to 3 years.
  • Reconstituted: refrigerate at 2 to 8 °C; use within 28 days; do not freeze the liquid solution.
  • Allow vials to reach room temperature before opening to minimize condensation; protect from light.
  • Discard if discoloration, cloudiness, or particulate matter is observed.

Supplies Needed

Plan based on an 8 to 16 week daily protocol with gradual titration (2 mg week 1, then 4 mg daily).

Peptide Vials (Ara-290, 16 mg each):

  • 8 weeks: ~14 vials.
  • 12 weeks: ~21 vials.
  • 16 weeks: ~28 vials.

Insulin Syringes (U-100):

  • Per week: 7 syringes (1/day).
  • 8 weeks: 56. 12 weeks: 84. 16 weeks: 112.

Bacteriostatic Water (10 mL bottles):

  • 8 weeks (14 vials): 3 bottles. 12 weeks (21 vials): 5 bottles. 16 weeks (28 vials): 6 bottles.

Alcohol Swabs:

  • Per week: 14 swabs.
  • 8 weeks: 112 (2 x 100-count). 16 weeks: 224 (3 x 100-count).

Important Notes

Practical considerations for consistency and safety.

  • Use a new sterile insulin syringe for each injection; dispose in a sharps container.
  • Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation and prevent

lipohypertrophy.

  • Inject slowly; wait a few seconds before withdrawing the needle.
  • Document daily dose and injection site to maintain consistency.
  • No clinically significant adverse effects were reported at 4 mg/day in 28-day clinical trials.

How This Works

Ara-290 (cibinetide) binds to the innate repair receptor (IRR), a heterodimer of EPOR and CD131 (bc subunit), which is distinct from the classical erythropoietin receptor. This selective binding triggers anti-apoptotic and anti-inflammatory signaling cascades that protect tissues and promote repair without stimulating erythropoiesis. Preclinical research demonstrates that Ara-290 can reprogram a pro-inflammatory, tissue-damaging environment into one favoring healing and regeneration. Additionally, analgesic effects have been observed through immunomodulation and direct inhibition of TRPV1 ion channels activated by capsaicin.

Benefits & Side Effects

Observations from preclinical and clinical literature.

  • Neuroprotection: Clinical trials in diabetic neuropathy showed improvements in HbA1c, lipid profiles,

and neuropathic pain scores with 4 mg daily dosing.

  • Nerve regeneration: In sarcoidosis-associated small-fiber neuropathy, treatment led to significant

increases in corneal nerve fiber density and improved symptoms compared to placebo.

  • Tissue protection: Anti-inflammatory and anti-apoptotic effects observed across multiple organ systems

in preclinical models.

  • No erythropoietic effects: Unlike full EPO, Ara-290 does not stimulate red blood cell production,

avoiding related side effects.

  • Tolerability: Well tolerated in clinical studies; occasional mild injection-site reactions (redness, transient

discomfort) may occur with subcutaneous administration.

Lifestyle Factors

Complementary strategies for best outcomes.

  • Optimize glycemic control through diet and medication adherence if addressing diabetic neuropathy.
  • Incorporate regular physical activity appropriate to individual capacity to support nerve health and

circulation.

  • Prioritize adequate sleep and stress management to support tissue repair processes.
  • Avoid smoking and limit alcohol consumption, both of which can exacerbate neuropathic conditions.

Injection Technique

General subcutaneous guidance from clinical best-practice resources.

  1. Clean the vial stopper and skin with alcohol; allow to dry.
  2. Pinch a skinfold; insert the needle at 45 to 90 degrees into subcutaneous tissue.
  3. Do not aspirate for subcutaneous injections; inject slowly and steadily.
  4. Wait 5 to 10 seconds before withdrawing; dispose of syringe in sharps container.
  5. Rotate sites systematically (abdomen, thighs, upper arms) to avoid lipohypertrophy.
