Aurinia Commends 2024 Updated ACR Guidelines for Screening, Treatment, and Management of Lupus Nephritis

New Guidelines Presented at ACR Convergence 2024 Recommend First-Line Therapy with LUPKYNIS^® (voclosporin) as Part of a Triple Immunosuppressive LN Treatment Regimen

Aurinia Pharmaceuticals Inc. (NASDAQ: AUPH) (Aurinia or the Company) commends the American College of Rheumatology (ACR) for their 2024 evidence-based guidelines for the screening, treatment, and management of lupus nephritis (LN), which prioritize the urgent need to use efficacious treatments to avoid nephron loss and preserve kidney function.

The guidelines call for a triple immunosuppression treatment regimen for LN, with first line use of advanced therapies like LUPKYNIS for three to five years. Importantly, the guidelines suggest that steroids should be rapidly tapered to <5 mg/day by six months as the highest acceptable maintenance dose of steroids. The guidelines also call for achieving a proteinuria target of <0.5g/g urine protein creatinine ratio (UPCR) by 12 months of treatment.

The recommendations included within the guidelines for use of LUPKYNIS to treat LN were based on the AURORA Clinical Program, including the Phase 3 AURORA 1 clinical study. In AURORA 1, patients were 81% more likely to achieve a complete renal response¹ at 52 weeks (40.8 vs 22.5 – OR 2.7) with LUPKYNIS in combination with mycophenolate mofetil (MMF) and low-dose glucocorticoids, compared to MMF and low-dose glucocorticoids alone. Additionally, > 80% of patients were tapered to a steroid dose of <2.5mg / day by 16 weeks per the AURORA protocol, making LUPKYNIS the only therapy to meet and exceed the new guideline steroid target of <5mg /day by 6 months in randomized clinical trials.

LUPKYNIS, the only FDA-approved CNI therapy for the treatment of adult patients with active LN in combination with other immunosuppressive therapies​, has demonstrated broad clinical utility across biopsy class, baseline eGFR, proteinuria range, race, ethnicity, age, and gender. Please see Indication and Important Safey Information, including Boxed Warning, below.

The guidelines recommend routine urine screening for proteinuria at least every six to 12 months in patients with SLE without known kidney disease, or when experiencing extra-renal flares. They also conditionally recommend performing a kidney biopsy in patients with SLE who have high levels of protein in the urine (> 0.5 g/g) and/or impaired kidney function not otherwise explained.

“We applaud ACR’s critical and timely guidelines to improve the management of lupus nephritis for this underserved patient population. They provide clear guidance for the importance of early diagnosis and starting with triple immunosuppression therapy with CNIs like LUPKYNIS to help achieve a complete renal response and aid in preserving kidney function for adults living with lupus nephritis,” said Dr. Greg Keenan, Chief Medical Officer at Aurinia.

The updated ACR guidelines for the diagnosis and treatment of LN are based on systematic evidence reviews, feedback from a panel of people living with LN, and input from rheumatologists and nephrologists.

About LUPKYNIS

LUPKYNIS is a novel, structurally modified calcineurin inhibitor (CNI) with a dual mechanism of action, acting as an immunosuppressant through inhibition of T-cell activation and cytokine production and promoting podocyte stability in the kidney. The AURORA Clinical Program, comprised of the AURORA 1 pivotal trial and AURORA 2 extension trial, demonstrated the importance of LUPKYNIS plus standard of care to preserve kidney health in patients with active LN without reliance on chronic high-dose glucocorticoids. It is the only clinical program to include three years of LN treatment and follow-up with mycophenolate mofetil (MMF) and steroids.

About Aurinia

Aurinia Pharmaceuticals is a fully integrated biopharmaceutical company focused on delivering therapies to people living with autoimmune diseases with high unmet medical needs. In January 2021, the Company introduced LUPKYNIS^® (voclosporin), the first FDA-approved oral therapy dedicated to the treatment of adult patients with active lupus nephritis. Aurinia is also developing AUR200, a differentiated, potential best-in-class therapy for autoimmune diseases that targets both BAFF (B-cell Activating Factor) and APRIL (A Proliferation-Inducing Ligand).

INDICATION AND IMPORTANT SAFETY INFORMATION

INDICATION

LUPKYNIS is indicated in combination with a background immunosuppressive therapy regimen for the treatment of adult patients with active lupus nephritis (LN).

Limitations of Use: Safety and efficacy of LUPKYNIS have not been established in combination with cyclophosphamide. Use of LUPKYNIS is not recommended in this situation.

IMPORTANT SAFETY INFORMATION

BOXED WARNINGS: MALIGNANCIES AND SERIOUS INFECTIONS

Increased risk for developing malignancies and serious infections with LUPKYNIS or other immunosuppressants that may lead to hospitalization or death.

CONTRAINDICATIONS: LUPKYNIS is contraindicated in patients taking strong CYP3A4 inhibitors because of the increased risk of acute and/or chronic nephrotoxicity, and in patients who have had a serious/severe hypersensitivity reaction to LUPKYNIS or its excipients.

WARNINGS AND PRECAUTIONS

Lymphoma and Other Malignancies: Immunosuppressants, including LUPKYNIS, increase the risk of developing lymphomas and other malignancies, particularly of the skin. The risk appears to be related to increasing doses and duration of immunosuppression rather than to the use of any specific agent.

Serious Infections: Immunosuppressants, including LUPKYNIS, increase the risk of developing bacterial, viral, fungal, and protozoal infections, including opportunistic infections which lead to serious, including fatal outcomes.

Nephrotoxicity: LUPKYNIS, like other calcineurin inhibitors (CNIs), may cause acute and/or chronic nephrotoxicity. The risk is increased when CNIs are concomitantly administered with drugs associated with nephrotoxicity. Monitor eGFR regularly.

Hypertension: Hypertension is a common adverse reaction of LUPKYNIS therapy and may require antihypertensive therapy. Monitor blood pressure regularly.

Neurotoxicity: LUPKYNIS, like other CNIs, may cause a spectrum of neurotoxicities: severe include posterior reversible encephalopathy syndrome (PRES), delirium, seizure, and coma; others include tremor, paresthesia, headache, and changes in mental status and/or motor and sensory functions. Monitor for neurologic symptoms.

Hyperkalemia: Hyperkalemia, which may be serious and require treatment, has been reported with CNIs, including LUPKYNIS. Concomitant use of agents associated with hyperkalemia may increase the risk for hyperkalemia. Monitor serum potassium levels periodically.

QTc Prolongation: LUPKYNIS prolongs the QTc interval in a dose-dependent manner when dosed higher than the recommended lupus nephritis therapeutic dose. The use of LUPKYNIS in combination with other drugs that are known to prolong QTc may result in clinically significant QT prolongation.

Immunizations: Avoid the use of live attenuated vaccines during treatment with LUPKYNIS. Inactivated vaccines noted to be safe for administration may not be sufficiently immunogenic during treatment with LUPKYNIS.

Pure Red Cell Aplasia: Cases of pure red cell aplasia (PRCA) have been reported in patients treated with another CNI immunosuppressant. If PRCA is diagnosed, consider discontinuation of LUPKYNIS.

Drug-Drug Interactions: Avoid co-administration of LUPKYNIS and strong CYP3A4 inhibitors or with strong or moderate CYP3A4 inducers. Co-administration of LUPKYNIS with strong CYP3A4 inhibitors is contraindicated. Reduce LUPKYNIS dosage when co-administered with moderate CYP3A4 inhibitors. Avoid use of LUPKYNIS with strong or moderate CYP3A4 inducers.

ADVERSE REACTIONS

The most common adverse reactions (≥3%) were glomerular filtration rate decreased, hypertension, diarrhea, headache, anemia, cough, urinary tract infection, abdominal pain upper, dyspepsia, alopecia, renal impairment, abdominal pain, mouth ulceration, fatigue, tremor, acute kidney injury, and decreased appetite.

SPECIFIC POPULATIONS

Pregnancy: Avoid use of LUPKYNIS.

Lactation: Consider the mother’s clinical need for LUPKYNIS and any potential adverse effects to the breastfed infant when prescribing LUPKYNIS to a lactating woman.

Renal Impairment: LUPKYNIS is not recommended in patients with baseline eGFR ≤45 mL/min/1.73 m ² unless benefit exceeds risk. If used in this population, reduce LUPKYNIS dose.

Hepatic Impairment: For mild or moderate hepatic impairment, reduce LUPKYNIS dose. Avoid use with severe hepatic impairment.

Please see Prescribing Information, including Boxed Warning, and Medication Guide for LUPKYNIS.
