CLINICAL RATIONALE

Immunoglobulin A Nephropathy

Immunoglobulin A nephropathy (IgAN), also known as Berger’s disease, is a kidney disease that occurs when IgA deposits build up in the kidneys, causing inflammation that damages the glomeruli, in turn causing the kidneys to leak blood and protein into the urine. The damage may lead to scarring of the nephrons that progresses slowly over many years. Eventually, IgAN can lead to end-stage renal disease (ESRD).(2)

Kidney biopsy is required to confirm the diagnosis of IgAN as there are no validated diagnostic serum or urine biomarkers for IgAN. Biopsy is indicated when a patient has signs of severe or progressive disease. After a diagnosis has been established, guidelines recommend that all patients with IgAN be assessed for secondary causes (e.g., liver cirrhosis, HIV, hepatitis, inflammatory bowel disease).(2)

The primary focus of IgAN management should be optimized supportive care (e.g., blood pressure management, maximally tolerated angiotensin-converting-enzyme inhibitor [ACEi] or angiotensin II blocker [ARB], lifestyle modification, address cardiovascular risk). Guidelines recommend that all patients with proteinuria greater than 0.5 g/d be treated with an ACEi or ARB irrespective of whether they have hypertension.(2) Recent literature also supports the use of sodium-glucose cotransporter-2 inhibitors (SGLT2i) as a component of maximal supportive care.(2,3) Furthermore, recent guidelines recommend simultaneous commencement of disease-modifying therapy and therapies to manage the consequences of IgAN-induced nephron loss.(2)

Guidelines define a patient with IgAN at risk of progressive loss of kidney function if they have a proteinuria greater than or equal to 0.5 g/d (or equivalent).(2) Proteinuria of 0.5 g/d is approximately equivalent to a urine protein to creatinine ratio (UPCR) of 0.44 g/g.(4) Systemic glucocorticoids have no proven impact on levels of pathogenic forms of IgA or IgA immune complexes and are used to manage glomerular inflammation. However, Tarpeyo (Nefecon) is recommended in the 2024 KDIGO guidelines as efficacy data supports a reduction in pathogenic IgA and IgA immune complexes.(2) The American Journal of Kidney Disease (AJKD) recommends corticosteroids (targeted release budesonide, Nefecon, or reduced dose corticosteroids) for high-risk patients with inflammatory lesions seen on kidney biopsy.(3) Most literature supports some use of corticosteroids as part of a treatment regimen however, the dose and duration is questionable.(2,3) Furthermore, long-term outcomes-based comparative studies for corticosteroids in the IgAN setting is lacking and future studies are needed to determine any clinical significance. It is further noted that the following patient characteristics are likely to increase the risks of systemic glucocorticoid toxicity:(2)

  • eGFR less than 30 mL/min/1.73 m^2
  • Diabetes and prediabetes
  • Obesity
  • Latent infections (e.g., viral hepatitis, tuberculosis)
  • Active peptic ulceration
  • Uncontrolled psychiatric illness
  • Osteoporosis
  • Cataracts

The goal of treatment in patients with IgAN at risk of progressive loss of kidney function is to reduce the rate of loss of kidney function to less than 1 mL/min per year for the rest of the patient's life. An additional treatment goal is the reduction of proteinuria to less than 0.5 g/d (or equivalent).(2)

Efficacy

Vanrafia is an endothelin type A (ETA) receptor antagonist. The effect of Vanrafia on proteinuria was assessed in a randomized, double-blind, placebo-controlled, multicenter, global study (ALIGN, NCT04573478) in adults with biopsy-proven primary IgAN, an eGFR greater than or equal to 30 mL/min/1.73 m^2, and urine protein greater than or equal to 1 g/day on a stable dose of maximally tolerated renin angiotensin system (RAS) inhibitor for a minimum of 12 weeks. The study included two cohorts: a main cohort of 340 patients and an exploratory cohort of 64 patients who were also on a stable dose of sodium glucose co-transporter 2 inhibitor (SGLT2i) at baseline. Patients with chronic kidney disease due to another condition in addition to IgAN or those who had been recently treated with systemic immunosuppressants were excluded. Patients were randomized (1:1) to receive either Vanrafia 0.75 mg or placebo once daily. RAS inhibitor therapy was continued throughout the study. Rescue immunosuppressive treatment could be initiated per investigator discretion during the trial.(1)

The primary endpoint was the percent reduction in UPCR at Week 36 relative to baseline and the results were as follows:(1)

Safety

Vanrafia has a boxed warning for embryo-fetal toxicity:(1)

  • Vanrafia may cause major birth defects if used during pregnancy
  • Exclude pregnancy before start of treatment
  • Use effective contraception before start of treatment, during treatment and two weeks after treatment
  • Discontinue Vanrafia if pregnancy occurs

Vanrafia is contraindicated in the following:(1)

  • Pregnancy
  • Hypersensitivity
