A study to find out if BI 764198 helps adults and adolescents with a kidney condition called focal segmental glomerulosclerosis (FSGS)
EU CTIS ID: 2025-522191-86-00
What this study is testing
The primary objective is to demonstrate superiority of BI 764198 for the mean relative change from baseline to Week 104 in 24-hour urinary protein-to-creatinine ratio (UPCR, measured in mg/g) in participants with pFSGS or those with gain-of-function mutations, some of whom are on background calcineurin inhibitor (CNI) treatment.
- Therapeutic confirmatory (Phase III)

Who can take part
You may be able to join if
- 1. Male or female participants ≥12 years old on the day of signing informed consent/assent (Visit 1)
- 2. Weight of ≥40 kg at the screening visit (Visit 1)
- 3. Body Mass Index (BMI) of ≤40 kg/m2 at the screening visit (Visit 1)
- 4. Participants with a diagnosis prior to the screening visit (Visit 1) of either: - biopsy-confirmed pFSGS (based on Investigator’s judgement) OR - genetic FSGS resulting from a gain-of-function gene mutation in the TRPC6 gene (based on historical genetic test)
- 5. UPCR ≥1500 mg/g based on the mean of the spot urine sample and first morning void urine sample (both assessed by central laboratory) at the screening visit (Visit 1)
- 6. Estimated glomerular filtration rate (eGFR) - For adult participants (≥18): ≥25 mL/min/1.73 m2 (CKD-EPI formula based on serum cystatin C) at the screening visit (Visit 1) - For adolescent participants (12 to <18 years); ≥25 mL/min/1.73 m2 based on CKiD U25 formula using height and serum cystatin C at the screening visit (Visit 1)
You likely can't join if
- 1. Known monogenic or syndromic causes of FSGS (with the exception of TRPC6 gain-of-function gene mutations)
- 2. Clinical or histologic evidence of secondary maladaptive or toxic forms of FSGS (based on Investigator’s judgement)
- 3. FSGS of undetermined cause (FSGS-UC) with a diagnosis prior to the screening visit (Visit 1) (based on Investigator’s judgement)
- 4. A history of organ transplantation or planned organ transplantation during the course of the trial
- 5. Use of intravenous immunosuppressive agents (e.g. cyclophosphamide, rituximab, obinutuzumab) in the last 6 months prior to screening (Visit 1)
- Further exclusion criteria apply.
