What You Need to Know Before You Apply

What is the purpose of this trial?

Multicenter study designed to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of BION-1301 in healthy volunteers and adults with IgA Nephropathy (IgAN).

Will I have to stop taking my current medications?

The trial requires that participants with IgA Nephropathy be stable on their current dose of ACE inhibitors or ARBs for at least 3 months before joining. However, if you are taking systemic corticosteroids or other immunosuppressive therapies, you must stop these at least 3 months before starting the trial.

Is BION-1301 safe for humans?

Preliminary results from studies on anti-APRIL therapies, including those similar to BION-1301, suggest they are generally well-tolerated in humans, with ongoing research to confirm their safety. ^{1 2 3 4 5}

How is the drug BION-1301 unique for treating IgA Nephropathy?

BION-1301 is unique because it is an anti-APRIL monoclonal antibody, which targets a specific protein involved in the immune response, potentially reducing the production of IgA antibodies that contribute to kidney damage in IgA Nephropathy. This mechanism is different from other treatments that may not specifically target this pathway. ^{6 7 8 9 10}

What data supports the effectiveness of the drug BION-1301 for IgA Nephropathy?

Research shows that targeting APRIL, a protein involved in IgA nephropathy, with antibodies like BION-1301 can reduce harmful immune responses in the kidneys. Studies in animals and early human trials suggest that blocking APRIL can lower protein levels in urine and slow kidney damage. ^{1 2 3 4 11}

Published Research Related to This Trial

In a phase 2 trial involving 155 adults with IgA nephropathy, treatment with sibeprenlimab for 12 months led to a significant reduction in proteinuria compared to placebo, with reductions of 47.2% to 62.0% depending on the dosage.

The safety profile of sibeprenlimab was comparable to placebo, with adverse event rates of 78.6% in the treatment groups versus 71.1% in the placebo group, indicating that sibeprenlimab is a potentially safe option for patients at high risk of disease progression.

The study confirms that APRIL plays a pathogenic role in IgA nephropathy (IgAN) and demonstrates that neutralizing APRIL with a monoclonal antibody (4540) effectively reduces harmful immune responses in a mouse model, leading to lower serum IgA levels and kidney deposits of IgA, IgG, and C3.

The humanized antibody VIS649 showed promising results in non-human primates, achieving up to a 70% reduction in serum IgA levels and a decrease in specific B cell populations, suggesting its potential as a safe and effective treatment for IgAN in clinical settings.

VIS649 (sibeprenlimab) was found to be safe and well tolerated in a phase 1 study involving 51 healthy adults, with no serious adverse events reported, indicating a favorable safety profile for further development.

The drug effectively suppressed APRIL and various immunoglobulins in a dose-dependent manner, while still allowing for a normal immune response to a tetanus/diphtheria vaccine, suggesting it may be a promising treatment for IgA nephropathy without compromising vaccine efficacy.

APRIL plays a crucial role in the regulation of B cells and is implicated in the development of IgA nephropathy (IgAN), the most common primary glomerulonephritis, which can lead to severe kidney disease.

Preliminary clinical trial data suggest that inhibiting APRIL may reduce proteinuria and slow kidney disease progression in IgAN, prompting the development of several anti-APRIL drug candidates currently in clinical trials.

APRIL is a key player in the development of immunoglobulin A nephropathy (IgAN), as it is linked to B-cell dysregulation and the overproduction of harmful IgA1, with higher levels correlating to more severe disease.

Anti-APRIL therapies have shown promise in reducing harmful IgA1 levels and improving kidney inflammation, with several new drugs currently being tested for their safety and effectiveness in treating IgAN.

In a study of eight patients with idiopathic membranous nephropathy (IMN), treatment with the anti-CD20 antibody rituximab led to a significant reduction in proteinuria, with levels decreasing by 66% after 12 months, indicating effective disease management.

Rituximab was found to be safe, with no major drug-related side effects reported, and it resulted in sustained disease remission, suggesting a more favorable long-term risk/benefit profile compared to traditional immunosuppressive therapies.

Patients with IgA nephropathy (IgAN) showed a significantly reduced immune response to nasal immunization with cholera toxin subunit B (CTB), indicating a defect in their mucosal IgA immune response compared to healthy controls.

The study suggests that while IgAN patients have a compromised initial immune response to mucosal antigens, they may still develop a hyperresponsive immune reaction upon subsequent parenteral immunization, highlighting the need for more frequent antigen exposure to establish effective mucosal immunity.

The study developed two monoclonal antibodies that specifically recognize hypo-galactosylated immunoglobulin A1 (HG-IgA1), which is significantly elevated in patients with IgA nephropathy (IgAN) compared to healthy controls and patients with other kidney diseases.

These antibodies showed strong binding to serum IgA from IgAN patients, indicating their potential as a reliable tool for screening and diagnosing IgAN, based on a study involving 49 IgAN patients, 48 patients with other kidney diseases, and 41 healthy controls.
