What is the purpose of this trial?

This trial tests a new treatment called MZE829, a potential drug for individuals with a specific type of chronic kidney disease. The trial aims to determine the safety of MZE829, its tolerability, and its effectiveness in reducing albuminuria, a condition characterized by excessive protein in the urine. The trial includes two groups: one for participants with kidney disease and diabetes, and another for those with kidney disease without diabetes. Suitable candidates have a high-risk APOL1 gene type and ongoing kidney issues with high protein levels in their urine. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that MZE829 is likely to be safe for humans?

Research shows that MZE829 is being tested for safety and tolerability. In earlier studies, healthy adults took MZE829 without major problems. This treatment is an oral pill designed to help with certain kidney diseases.

The earlier research found that most people tolerated MZE829 well, experiencing no severe reactions. Some had mild side effects, but serious ones were rare.

This trial is in the middle stage of testing (Phase 2), indicating that the treatment has shown some safety in earlier studies. However, researchers are still assessing its safety for people with kidney disease. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for kidney disease?

Researchers are excited about MZE829 for kidney disease because it introduces a novel approach compared to current treatments like ACE inhibitors and angiotensin II receptor blockers. Unlike these standard options, which primarily focus on controlling blood pressure to slow kidney damage, MZE829 targets specific pathways involved in kidney inflammation and fibrosis, potentially offering more direct protection to kidney tissues. This unique mechanism could lead to improved outcomes for patients, especially those with chronic kidney disease both with and without diabetes.

What evidence suggests that MZE829 might be an effective treatment for kidney disease?

Research shows that MZE829 is a pill designed to block the APOL1 gene, which is linked to kidney disease. Studies suggest it could effectively treat kidney disease caused by this gene. Early results indicate that MZE829 may reduce the amount of albumin in urine, a marker of kidney damage, potentially slowing the progression of kidney disease. Positive initial data from human trials support its potential effectiveness and safety for individuals with this type of kidney disease. Participants in this trial will receive MZE829, with cohorts including those with chronic kidney disease, both with and without concurrent diabetes. ^{1 2 6 7 8}

Are You a Good Fit for This Trial?

This clinical trial is for adults with a specific genetic risk (APOL1 high-risk genotype) for kidney disease who have chronic kidney disease with persistent albuminuria. It's not open to those who've had organ or bone marrow transplants, are pregnant or nursing, have conditions affecting drug absorption like past bariatric surgery, recent cancer history except certain low-risk types, or Type I diabetes.

Inclusion Criteria

I have a high-risk APOL1 genotype.

I have long-term kidney disease with ongoing protein in my urine.

Exclusion Criteria

I have had an organ or bone marrow transplant.

Pregnant or currently nursing

I have a condition that could change how drugs are absorbed, like a history of weight loss surgery.

In a clinical study involving 11 lupus nephritis patients in China, mizoribine (MZR) demonstrated a high remission rate of 72.7% after 6 months, with significant reductions in proteinuria, indicating its efficacy as a treatment option.

No adverse events were reported during the study, suggesting that MZR is a safe option for inducing remission in lupus nephritis, even for patients who did not respond to other treatments.

Mizoribine (MZR) showed similar efficacy to mycophenolate mofetil (MMF) in preventing acute rejection episodes in kidney transplant patients, with a noninferior rate of biopsy-proven acute rejection (6.4% for MZR vs 1.8% for MMF).

While MZR was effective, it was associated with a significant increase in uric acid levels compared to MMF, indicating a potential safety concern that needs to be monitored.

In a study of 40 kidney transplant patients, high-dose Mizoribine (6 mg/kg/day) combined with cyclosporine and other immunosuppressants achieved a 100% graft survival rate over two years, comparable to the 94.7% rate in the control group using mycophenolate mofetil.

The MZR group had a significantly lower incidence of cytomegalovirus (CMV) disease (0%) compared to the MMF group (18.4%), indicating that high-dose MZR may provide effective immunosuppression with a reduced risk of viral infections.

In a study of 884 patients with primary proteinuric kidney disease, 60% were treated with steroids, and 62% of these patients experienced at least one steroid-associated adverse event (SAAE), with a frequency of 293 per 1000 person-years.

Steroid treatment was linked to a 40% increased risk of any SAAE, with higher doses significantly raising the risk; a 1-mg/kg per day increase in steroid dose resulted in a 2.5-fold increase in SAAE risk, highlighting the need for careful monitoring and potential steroid minimization strategies.

In a pharmacokinetic study involving 9 patients with child-onset glomerulonephritis, mizoribine (MZR) was administered at doses of 60-300 mg/day, showing a peak serum concentration reached in about 2.94 hours and a half-life of approximately 1.96 hours.

The study provided important pharmacokinetic parameters for MZR, indicating a significant urinary excretion rate of 49.1%, which may help optimize treatment strategies for pediatric patients with glomerulonephritis.
