Ara-290 (16 mg Vial) Dosage Protocol

Ara-290 Dosage Chart

Ara-290 is dosed at 2 mg–4 mg daily via subcutaneous injection in educational protocols. A 16 mg vial reconstituted with bacteriostatic water yields about 8 mg/mL. This information is for research and educational use only.

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.

Educational guide for reconstitution and daily dosing

Standard / Gradual Approach (2.0 mL = 8 mg/mL)

Phase	Daily Dose (mg)	Units (per injection) (mL)
Week 1	2 mg (2,000 mcg)	25 units (0.25 mL)
Weeks 2–8 (or up to 16)	4 mg (4,000 mcg)	50 units (0.50 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

Important: This guide is for educational purposes only and is not medical advice. For research use only. Not for human consumption.

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

Concise summary of the once-daily regimen based on clinical trial designs.

Goal: Support tissue protection, anti-inflammatory signaling, and neuropathic symptom management via IRR activation.
Schedule:Daily subcutaneous injections for 4–8 weeks (clinical trials used 28-day protocols; extension to 8–16 weeks based on individual response).
Dose Range: 2–4 mg daily; 4 mg is the established target dose.
Reconstitution: 2.0 mL per 16 mg vial (8 mg/mL) for accurate unit measurements.
Storage: Lyophilized refrigerated or frozen; reconstituted refrigerated up to 28 days.

Suggested daily titration approach reflecting clinical study parameters.

Start: 2 mg daily during week 1 to assess tolerance.
Target: 4 mg daily from week 2 onward
Frequency: Once per day (subcutaneous).
Vial Duration: 4–8 weeks standard; may extend to 16 weeks based on individual assessment.
Timing: Any consistent time daily; rotate injection sites.

Proper storage preserves peptide integrity and potency.

Lyophilized: Refrigerate at 2–8 °C (35.6–46.4 °F) for up to 2 years; freeze at −20 °C (−4 °F) for extended storage up to 3 years
Reconstituted: Refrigerate at 2–8 °C (35.6–46.4 °F); use within 28 days and do not freeze the liquid solution.
Allow vials to reach room temperature before opening to minimize condensation; protect from light.
Allow vials to reach room temperature before reconstitution to prevent condensation and pressure issues.
Discard if discoloration, cloudiness, or particulate matter is observed.

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.

Ara-290 (cibinetide) binds to the innate repair receptor (IRR), a heterodimer of EPOR and CD131 (βc 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.

Observations from preclinical and early research 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 (objective nerve regrowth) 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.

Complementary strategies that may support therapeutic goals.

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.

General subcutaneous guidance from clinical best-practice resources.

Clean the vial stopper and injection site with alcohol swabs; allow to dry completely.
Select a fatty subcutaneous site: lower abdomen (at least 2 inches from navel), outer thigh, or back of upper arm.
Pinch a skinfold; insert the needle at 45–90° into subcutaneous tissue.
Aspiration is not required for subcutaneous injections; inject slowly and steadily.
Rotate sites systematically with each dose to avoid lipohypertrophy and local tissue changes.
After injection, withdraw the needle and apply gentle pressure with clean gauze; do not rub the site.
