Examples of highly reliable contraception methods include stable oral, implanted, transdermal, or injected contraceptive hormones associated with the inhibition of ovulation or an intrauterine device. One additional barrier method must also be used during vaginal sexual activity, such as a diaphragm, diaphragm with spermicide (preferred), or male partner's use of male condom or male condom with spermicide (preferred), from Day 1\u002FRandomization until 28 days after the last dose of study medication. Female subjects of childbearing potential are defined as those who are fertile after menarche, unless permanently sterile; permanent sterilization methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy. All female subjects of childbearing potential must have a negative serum pregnancy test result at screening (Visit 1) and a negative urine pregnancy test result, with positive results confirmed by serum, at every study visit from Day 1 (Visit 3) and after.\n\nNote: Before menarche, pregnancy testing and contraceptive use are not required. However, subjects and their parents\u002Flegal guardians must be advised that, immediately upon menarche, subjects will be required to begin pregnancy testing and initiate contraceptive use. This requirement cannot be waived.\n\n* The subject has participated in a study of another study medication within 28 days before screening or plans to participate in such a study during the course of this study.\n* The subject has had prior exposure to sparsentan.\n* The subject or parent\u002Flegal guardian (as appropriate), in the opinion of the Investigator, are unable to adhere to the requirements of the study including but not limited to, a history of noncompliance and\u002For any other reason that causes the Investigator to believe the subject would not be a good candidate for the study.\n* For Population 3 - the subject is unable to swallow the study medication tablets whole.","ALL","1 Year","17 Years",{"count":509,"type":510},67,"ESTIMATED","INTERVENTIONAL",[513],"PHASE2","To evaluate the safety, efficacy and tolerability of sparsentan oral suspension and tablets, and assess changes in proteinuria after once-daily dosing over 108 weeks.",[516,517,518,519,520],"Focal Segmental Glomerulosclerosis","Minimal Change Disease","Immunoglobulin A Nephropathy","IgA Vasculitis","Alport Syndrome",[522],"Alport, AS, FSGS, IgAN, IgAV, MCD, pediatrics, peds","2026-05-08",{"date":525,"type":526},"2026-05-12","ACTUAL",{"date":528,"type":526},"2021-08-12",{"date":530,"type":510},"2027-04-12",{"name":5,"class":6},47]
