New drug aims to stop kidney disease relapses
NCT ID NCT07499700
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a drug called BAT4406F in people with two rare kidney conditions: Minimal Change Disease and Focal Segmental Glomerulosclerosis. The goal is to see if it can reduce protein in the urine and prevent the disease from coming back. About 192 participants will receive either the drug or a placebo by IV infusion, and researchers will track their progress over several months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BAT4406F injection
- What this could lead to
- If it works, this could offer a new treatment option to control protein leakage and reduce relapses in people with MCD or FSGS.
- What could go wrong
- This is an early-to-mid-stage trial with only 192 participants, so results may not apply to everyone. The drug may not work better than placebo, and side effects are still being studied.

Inclusion Criteria: 1. Clinically diagnosed with NS, with a pathological diagnosis of Minimal change disease/Focal segmental glomerulosclerosis confirmed by renal biopsy within 7 years (Minimal change disease) or 10 years (Focal segmental glomerulosclerosis) prior to screening, and who are responsive to corticosteroid therapy 2. The time since achieving complete remission following corticosteroid therapy for the most recent active or relapsed disease is within 8 weeks of baseline Exclusion Criteria: 1. Secondary Nephrotic Syndrome 2. Known genetic defects associated with Nephrotic Syndrome or a family history of Nephrotic Syndrome 3. Receipt of any B-cell depletion or B-cell-modifying therapy within 6 months prior to baseline 4. History of allergy to monoclonal antibodies; or a predisposition to allergies 5. Received treatment with immunosuppressants within 60 days prior to baseline 6. Received immunoglobulin within 90 days prior to baseline; or received immunomodulators such as thymosin within 4 weeks prior to baseline 7. Participation in a clinical trial of another investigational drug within 90 days prior to baseline or within 5 half-lives of the drug (whichever is longer), or plans to participate in a clinical trial of another drug during the study period 8. Marked abnormalities in liver or kidney function 9. Positive for hepatitis B surface antigen (HBsAg); or positive for hepatitis C virus (HCV) antibodies; or positive for Treponema pallidum antibodies; or history of Human Immunodeficiency Virus or positive for Human Immunodeficiency Virus antibodies
