Trial Summary

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop your current medications. However, if you are in the IgAN cohort, you must have been on a stable dose of renin-angiotensin system inhibitors for at least 3 months. Also, you cannot have taken prednisone over 20 mg per day for more than 14 days or any other immunosuppressants within 6 months.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop your current medications. However, if you are in the IgAN cohort, you must have been on a stable dose of renin-angiotensin system inhibitors for at least 3 months.

What data supports the idea that Ravulizumab for Lupus Nephritis and IgA Nephropathy is an effective treatment?

The available research does not provide specific data on Ravulizumab for Lupus Nephritis and IgA Nephropathy. Instead, it focuses on another drug, Belimumab, which has shown some effectiveness in treating Lupus Nephritis. Belimumab was found to reduce the risk of kidney-related events and improve kidney function in some patients. However, there is no direct comparison or data available for Ravulizumab in the provided information.12345

What safety data exists for Ravulizumab in treating Lupus Nephritis and IgA Nephropathy?

The provided research does not contain specific safety data for Ravulizumab (also known as Ultomiris, ravulizumab-cwvz, ALXN1210) in the treatment of Lupus Nephritis and IgA Nephropathy. The studies mentioned focus on other treatments such as Belimumab, Tacrolimus, and Rituximab for Lupus Nephritis. Further research or clinical trial data specific to Ravulizumab would be needed to answer this question.12678

Is the drug Ravulizumab a promising treatment for Lupus Nephritis and IgA Nephropathy?

Ravulizumab, similar to eculizumab, is a promising drug because it targets the complement system, which plays a key role in diseases like IgA nephropathy. Eculizumab has shown positive results in some cases, suggesting that Ravulizumab might also be effective.19101112

How is the drug Ravulizumab unique for treating lupus nephritis and IgA nephropathy?

Ravulizumab is unique because it is a long-acting complement inhibitor that targets the C5 protein, similar to eculizumab, which has shown promise in treating conditions like IgA nephropathy by reducing complement activation, a key factor in the disease's progression. This mechanism of action distinguishes it from other treatments that do not specifically target the complement system.19101112

What is the purpose of this trial?

This trial is testing the safety and effectiveness of a drug called ravulizumab, given through a vein, in patients with specific kidney diseases. The drug aims to reduce kidney damage by blocking part of the immune system.

Eligibility Criteria

This trial is for people with severe kidney inflammation due to Lupus Nephritis (LN) or IgA Nephropathy (IgAN). Participants must have protein in their urine and be vaccinated against certain infections. Those with LN need active disease treatment, while those with IgAN should be on stable blood pressure medication. People can't join if they have very low kidney function, used complement inhibitors before, have other major kidney diseases, uncontrolled high blood pressure, or recent heavy use of steroids/immunosuppressants.

Inclusion Criteria

I have been diagnosed with primary IgA nephropathy.
I have been vaccinated against meningitis.
I am vaccinated for Hib and pneumonia as required.

Exclusion Criteria

I have been diagnosed with a quickly worsening kidney condition.
I do not have significant kidney disease other than lupus nephritis or IgA nephropathy.
My kidney function is low, with an eGFR under 30.

Treatment Details

Interventions

  • Background Therapy
  • Ravulizumab
Trial Overview The study tests Ravulizumab's safety and effectiveness compared to a placebo in patients with LN or IgAN. All participants will continue their usual treatments too. Ravulizumab is given through an IV infusion to see if it can help by blocking part of the immune system that damages the kidneys.

Findings from Research

In a study of 1844 nephritis-naïve patients with systemic lupus erythematosus (SLE), low-dose intravenous belimumab (1 mg/kg monthly) significantly reduced the risk of de novo renal flares by nearly 3-fold compared to placebo.
Subcutaneous belimumab (200 mg weekly) also showed a protective effect against renal flares, while the standard approved dose of intravenous belimumab (10 mg/kg monthly) did not demonstrate clear protective benefits.
Effect of Belimumab on Preventing de novo Renal Lupus Flares.Parodis, I., Lindblom, J., Cetrez, N., et al.[2023]
In the phase 3 BLISS-LN study involving 448 patients with lupus nephritis, belimumab significantly improved kidney-related outcomes compared to placebo, with a higher percentage of patients achieving primary and complete renal responses, especially in relapsed patients.
The efficacy of belimumab was consistent regardless of whether patients received glucocorticoid pulses during induction therapy, indicating its potential as a reliable treatment option for both newly diagnosed and relapsed lupus nephritis.

In a 104-week Phase 3 trial involving 448 patients with lupus nephritis, adding belimumab to standard therapy significantly improved kidney responses, especially in patients with lower baseline urine protein/creatinine ratios.
Belimumab also reduced the risk of kidney-related events, death, and lupus nephritis flare, while slowing the decline in kidney function (eGFR) compared to standard treatment alone.
A secondary analysis of the Belimumab International Study in Lupus Nephritis trial examined effects of belimumab on kidney outcomes and preservation of kidney function in patients with lupus nephritis.Rovin, BH., Furie, R., Teng, YKO., et al.[2022]
