LUPKYNIS®

A calcineurin inhibitor (CNI) indicated in combination with a background immunosuppressive regimen for the treatment of adult patients with active

lupus nephritis

The first oral therapy approved for the treatment of

lupus nephritis

®

Lupus Nephritis (LN) Is Among the Most Severe and Dangerous Complications of Systemic Lupus Erythematosus (SLE)

SLE, commonly known as lupus, is a chronic autoimmune disease where the body's immune system mistakenly attacks its own healthy tissues and organs

Over 200,000 people in the United States are estimated to have SLE a, of which 20% to 60% develop LN b

Glomerulo-nephritis

LN occurs when the immune system attacks the kidneys

SLE/LN disproportionately affects women and people of color a

Measuring proteinuria (protein in the urine) is critical for monitoring disease activity and response to therapy c

Inflammation leads to blood and protein in the urine, impaired kidney function and even kidney failure

Proteinuria Reduction Is Associated with Long-Term Renal Preservation

The larger the initial reduction in proteinuria in the first several months of management, the lower the risk of ESKD

ESKD=end-stage kidney disease

a Adapted with permission from Chen et al., Clin J Am Soc Nephro 2008

b Retrospective analysis of patients (N=86) enrolled in the prospective, controlled study of plasmapheresis in severe LN to determine long-term prognosis of achieving partial response. Complete

® response was defined as SCr ≤1.4 mg/dL and proteinuria ≤0.33 g/day within 5 years of study entry, and partial response was defined as ≤25% increase in baseline SCr and ≥50% reduction in baseline proteinuria to ≤1.5 g/day (but >0.33 g/day) within 5 years of entering the study. Kidney survival was determined by kidney failure (≥6 mg/dL SCr or the initiation of kidney replacement 9

therapy).

2024 American College of Rheumatology (ACR) Lupus Nephritis Treatment Guideline Update a

In November 2024, the ACR released an updated guideline for the treatment of LN that emphasizes early and aggressive treatment to preserve kidney function

Specifically, this updated guideline now details the following:

Goal is complete renal response, including reduction in proteinuria to

≤0.5 mg/mg within 6-12 months

Triple immunosuppressive

therapy, including a calcineurin inhibitor (CNI) or belimumab as first-line therapy

LUPKYNIS is the only CNI that

is FDA approved for LN

Reduce corticosteroid dose to minimize toxicity, with a

goal of ≤5 mg/day by 6 months

of therapy

Aritinercept

A dual BAFF/APRIL inhibitor for the potential treatment of autoimmune diseases

®

Aritinercept Is a Dual BAFF/APRIL Inhibitor

Aritinercept contains a BCMA-engineered extracellular binding domain optimized for superior affinity to BAFF and APRIL (others use TACI-engineered extracellular binding domain)

BCMA has a stronger natural affinity for APRIL than TACI a

Aritinercept contains an IgG4 Fc domain with no appreciable effector function (others use IgG1 Fc domain)

IgG4 is considered the least inflammatory across the IgG subclasses, in part because it poorly activates the complement system b

BAFF APRIL

Aritinercept

® a Mathur et al., J Clin Med 2023

b Oskam et al., Front Immun 2023

BAFF=B cell-activating factor; APRIL=a proliferation-inducing ligand;

BCMA=B cell maturation antigen; TACI=transmembrane activator and 18

CAML interactor; Fc=fragment crystallizable; IgG4=immunoglobulin G4

Role of BAFF and APRIL

BAFF and APRIL are important cytokines that regulate B cell survival and differentiation, whose targets are expressed on B cells at different stages of B cell development a

Targeting both BAFF and APRIL depletes a broader set of B cells, including plasma cells, than targeting a single cytokine

Aritinercept may prevent the activation of autoreactive B cells and reduce their numbers and associated immunoglobulins (antibodies) in the body, thereby reducing important drivers of B cell-mediated autoimmune diseases
