Bottom line

Voclosporin is a synthetic analog of cyclosporine A modified at the amino acid-1 residue (the MeBmt position). It is a homodetic cyclic peptide and a calcineurin inhibitor. FDA-approved in January 2021 (Lupkynis) for the treatment of active lupus nephritis in combination with mycophenolate mofetil and corticosteroids. A pivotal phase 3 trial (AURORA-1) demonstrated superior renal response rates compared to standard of care. Unlike cyclosporine, voclosporin does not require therapeutic drug monitoring.

Mechanism and pharmacology

Voclosporin binds to cyclophilin A; the complex inhibits calcineurin, blocking IL-2 expression and T-cell-mediated immune responses. It also stabilizes podocytes in the kidney. The single amino-acid modification vs cyclosporine A alters binding affinity to calcineurin, leading to a more predictable pharmacokinetic profile and no requirement for therapeutic drug monitoring.

Dose and administration evidence

Approved labeled regimen

The label summary below is product-, indication-, and jurisdiction-specific; consult the full current label and a licensed clinician/pharmacist.

  • 23.7 mg (3 capsules of 7.9 mg) orally twice daily (approximately 12 hours apart).

  • Avoid use if baseline eGFR ≤45 mL/min/1.73 m² unless benefit outweighs risk.

  • If eGFR drops to 30–44 mL/min/1.73 m² during treatment: reduce dose to 15.8 mg (2 capsules) BID; if no improvement within 4 weeks, discontinue.

  • If eGFR drops to <30 mL/min/1.73 m²: discontinue voclosporin.

  • For severe renal impairment at baseline (eGFR 15–29 mL/min/1.73 m²): starting dose of 15.8 mg BID if used; discontinuation rules apply as above.

  • On empty stomach (1 hour before or 2 hours after a meal).

  • In combination with mycophenolate mofetil (MMF) and rapidly tapered corticosteroids.

Studied regimens (not recommendations)

High-dose regimen (39.5 mg BID) studied in phase 2 but associated with increased adverse events.

What is not established

  • Safety and efficacy in combination with cyclophosphamide.

  • Safety in severe renal impairment (eGFR less than 30 mL/min) or dialysis.

  • Pediatric use.

Safety

Established label risks

Boxed warning: VOCLOSPORIN is a calcineurin-inhibitor immunosuppressant associated with an increased risk of malignancies, including lymphoma and skin cancer, and an increased susceptibility to serious infections, including opportunistic infections. Use only in the recommended dose and in combination with mycophenolate mofetil and corticosteroids. Only physicians experienced in immunosuppressive therapy and management of lupus nephritis should prescribe.

  • Nephrotoxicity: eGFR reduction (typically reversible).

  • Hypertension.

  • QT prolongation (dose-dependent; ECGs recommended).

  • Increased risk of infections.

  • Diarrhea, headache, anemia, cough.

  • Fetal harm (based on mechanism; adequate contraception required).

Human-study signals

AURORA-1: Serious infections 10.2% vs 9.3% placebo. Malignancies 0.6% vs 0%. Deaths 1.7% vs 1.9%.

Unknowns and product-quality risks

Limited long-term safety data beyond 3 years.

Interactions and special populations

  • CYP3A4 substrate.

  • Moderate-strong CYP3A4 inhibitors (including grapefruit): increase voclosporin exposure; contraindicated with strong inhibitors.

  • CYP3A4 inducers: reduce exposure; avoid.

  • Pregnancy: based on animal data, may cause fetal harm.

  • Breastfeeding: not recommended.

Regulatory, compounding, and sport notes

  • FDA and EMA approved prescription only.

  • WADA: voclosporin was not identified by exact name in the 2026 Prohibited List, and this review did not identify a matching prohibited class. An unsupported assumption about performance effect is not a basis for classification; athletes should verify the exact product and current status.

  • Not interchangeable with cyclosporine or tacrolimus.

Evidence gaps

  • Long-term renal survival data.

  • Comparative effectiveness vs tacrolimus-based regimens.

  • Safety in sub-Saharan African and Latin American populations with LN.
