Can a pill calm the immune attack on kidneys?
NCT ID NCT05800873
First seen Aug 05, 2026 · Last updated Sep 16, 2026 · Updated 3 times
Summary
This trial tests an experimental oral drug called EVER001 in people with primary membranous nephropathy, a kidney disease where the immune system damages the kidney's filtering units, causing protein to leak into urine. The study aims to see if EVER001 can reduce proteinuria and lower harmful autoantibodies, potentially slowing disease progression. About 31 participants with biopsy-confirmed disease and high protein levels will receive the drug, with safety and effectiveness monitored over a year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- EVER001, an oral BTK inhibitor
- What this could lead to
- If successful, EVER001 could offer a new oral treatment option to reduce proteinuria and potentially slow kidney damage in people with primary membranous nephropathy.
- What could go wrong
- This is an early-phase trial with a small number of participants, so the drug may not prove effective or safe. Possible side effects are still being evaluated.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Having clinical diagnosis of primary membranous nephropathy, as verified by biopsy. 2. Have positive anti-PLA2R autoantibody test results \> 20 relative units (RU)/ml. 3. During screening at least one testing of proteinuria must be \>3.5 g/24h. 4. Have nephrotic range proteinuria for at least 8 weeks prior to Day 1 and no improvement (\<50% reduction) despite supportive therapy of ACE inhibitor or ARB unless contraindicated, for patients who have two tests of proteinuria during screening ≥8.0g/24h, the duration of nephrotic range proteinuria for at least 8 weeks is not required. Exclusion Criteria: 1. Non-primary membranous nephropathy or other condition affecting the kidney. 2. eGFR at screening \< 45 mL/min/1.73m2 or kidney function not stable . 3. Uncontrolled hypertension . 4. Serum albumin level at screening # 25g/l. 5. Have received: B-cell targeted therapy except rituximab at any time;Rituximab and the biosimilars within 2 years (participants with rituximab treatment between 1 and 2 years prior to Day 1 are eligible if there is documented evidence of B-cell repopulation to \>90% of Lower Limits of Normal Range.); Cyclophosphamide or Chlorambucil within 180 days;other immunosuppressive/immunomodulatory agents within 90 days;greater than 30mg/day prednisone or equivalence within 30 days. 6. Acute or chronic infection,including positivity of tuberculosis infection test. 7. Positive serology for TP,HIV, HBV, or HCV. 8. Lab testing abnormality as: WBC\< 3000/mm³, Lymphocyte \< 1000/ mm³, neutrophil \<1500/mm³, Hb \< 80g/L, Platelet count \<100×10e9/ L, Prothrombin time\>1.5×ULN, Activated partial thromboplastin time ≥1.5×ULN, Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≥ 1.5×ULN, alkaline phosphatase and bilirubin \>1.5×ULN. 9. Judged by the investigator that the participant is unlikely to comply with study procedures, restrictions, and requirements.
