Trial Summary

What is the purpose of this trial?

This trial aims to test the effectiveness and safety of crovalimab in adults and adolescents with aHUS. Crovalimab helps by calming an overactive immune system that can harm blood vessels and kidneys.

Will I have to stop taking my current medications?

The trial allows participants to continue taking certain medications like immunosuppressants, corticosteroids, mTOR inhibitors, or calcineurin inhibitors, as long as the dose has been stable for at least 28 days before starting the trial. The protocol does not specify about other medications, so it's best to discuss with the trial team.

What data supports the effectiveness of the drug Crovalimab for treating atypical hemolytic uremic syndrome?

Research on similar drugs like ravulizumab and eculizumab, which also target the complement system, shows they are effective in treating atypical hemolytic uremic syndrome by rapidly resolving symptoms and improving kidney function. This suggests that Crovalimab, which works in a similar way, may also be effective.12345

Eligibility Criteria

Adults and adolescents with atypical Hemolytic Uremic Syndrome (aHUS) who weigh at least 40 kg can join. They must be vaccinated against certain infections, agree to use contraception if applicable, and have a negative pregnancy test for females of childbearing potential. Those with prior kidney transplants due to aHUS or on stable doses of other treatments may also qualify.

Inclusion Criteria

I have been treated with eculizumab or ravulizumab.
I have shown improvement with a C5 inhibitor treatment.
For female participants of childbearing potential: an agreement to remain abstinent or use contraception

Exclusion Criteria

I have recently taken tranexamic acid.
I will start or have started PE/PI treatment within 8 weeks before my first crovalimab dose.
You have cryoglobulinemia when you are screened for the study, especially if you have recently been treated with a C5 inhibitor.

  • Crovalimab (Monoclonal Antibodies)
Trial OverviewThe trial is testing Crovalimab's effectiveness and safety in treating aHUS. It will involve participants who are new to treatment, those switching from other C5 inhibitors, and individuals with specific genetic variations related to the disease.

Findings from Research

Ravulizumab has shown long-term efficacy in treating atypical hemolytic uremic syndrome (aHUS), with a median follow-up of 76.7 weeks revealing sustained improvements in thrombotic microangiopathy (TMA) and kidney function in 58 patients.
The treatment demonstrated an acceptable safety profile, with most adverse events occurring early in the treatment and no cases of meningococcal infection or death during the follow-up period, indicating it is a safe option for long-term management of aHUS.
Long-Term Efficacy and Safety of the Long-Acting Complement C5 Inhibitor Ravulizumab for the Treatment of Atypical Hemolytic Uremic Syndrome in Adults.Barbour, T., Scully, M., Ariceta, G., et al.[2022]
Eculizumab and ravulizumab are both effective and safe treatments for atypical hemolytic uremic syndrome (aHUS), but ravulizumab is preferred due to its lower financial burden and less frequent dosing, making it more convenient for patients and caregivers.
Genetic mutations in complement factors are linked to a higher risk of disease recurrence, suggesting that treatment should start promptly upon identifying these mutations to prevent complications.
Eculizumab Versus Ravulizumab for the Treatment of Atypical Hemolytic Uremic Syndrome: A Systematic Review.Shahid, K., Qayyum, S.[2023]
In a clinical trial involving 10 pediatric patients with atypical hemolytic uremic syndrome (aHUS), switching from eculizumab to ravulizumab resulted in stable kidney function and hematologic parameters over a 52-week period, with no patients requiring dialysis.
Ravulizumab was found to be safe, with common adverse events being upper respiratory infections and oropharyngeal pain, but no serious infections or deaths reported, indicating a favorable safety profile for this long-acting C5 inhibitor.
The long-acting C5 inhibitor, ravulizumab, is efficacious and safe in pediatric patients with atypical hemolytic uremic syndrome previously treated with eculizumab.Tanaka, K., Adams, B., Aris, AM., et al.[2022]
