Eligibility
Inclusion criteria
Inclusion criteria: - Male and female patients 18 years to 75 years (both inclusive) of age on the day of signing informed consent. - Patients diagnosed with biopsy proven primary FSGS or documented TRPC6 gene mutation causing FSGS prior to screening visit. - Average UPCR = 1500 mg/g based on two 24 hour urine samples collected at least 7 days apart at screening. - Completion of initial corticosteroid therapy course (if applicable) or discontinuation due to intolerance before entry to the trial. - If applicable, corticosteroid therapy (i.e. prednisone) of =15 mg/day or =30 mg on alternate days with stable dose for at least 2 weeks at randomization, with no plan to change the dose during the study. - Patients treated with ACE inhibitors, ARBs, finerenone, aldosterone inhibitors, or SGLT2 inhibitors should be on a stable dose for at least 4 weeks prior to screening visit with no plan to change the dose during the study. - Body Mass Index (BMI) of = 40 kg/m2 at screening visit. - Women of childbearing potential (WOCBP) must be willing and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria is provided in the informed consent form (ICF). Men must be willing and able to use condom if their partner is a WOCBP. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 45 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 15
Exclusion criteria
Exclusion criteria: - Known monogenic (with the exception of TRPC6 gene mutations) or clinical or histologic evidence of secondary FSGS. - Documented Alport syndrome, Nail Patella syndrome, diabetic nephropathy, IgA nephropathy, lupus nephritis, or monoclonal gammopathy (e.g., multiple myeloma). - Concomitant use of calcineurin inhibitors. - Concomitant treatment with cytotoxic agents (cyclophosphamide, chlorambucil), or CD20 monoclonal antibody, e.g., rituximab, within 5 half-lives before screening visit. Note: use of other immunosuppression therapies considered as standard of care may be allowed as long as the patient remains on stable therapeutic dose throughout the study. - Estimated glomerular filtration rate (eGFR) 3X the upper limit of normal (ULN) at screening visit. - QTc intervals (QTcF) greater than 450 ms in males or greater than 470 ms in females, or any other clinically relevant ECG findings (at the investigator’s discretion) at screening visit. - Detection of graded cataract by LOCS III higher than NC1/NO1, C0, P0 in the slit lamp eye examination at screening visit. Planned cataract surgery during participation in the study. Patients with cataract who have undergone lens replacement are not excluded. - Women who are pregnant, nursing, or who plan to become pregnant while in the study. Further criteria apply.
