Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Is ≥ 18 years of age at the time of informed consent;
• Kidney biopsy-proven diagnosis of primary MCD or primary FSGS within the past 10 years. Subjects with kidney biopsy-proven diagnosis of primary MCD or primary FSGS greater than 10 years and less than 20 years prior to Screening who meet all other eligibility criteria may be enrolled after discussion with the Medical Monitor
• History of steroid-sensitive MCD or FSGS, defined as having achieved complete remission of proteinuria (reduction of proteinuria to \<0.5 g/g UPCR) after use of corticosteroids;
• Has experienced meaningful proteinuria in the last 2 years prior to Screening, defined as UPCR \>2.0 g/g, after attempted or completed tapering of steroids and/or CNIs that occurs within 6 months of the attempt or completion of tapering;
• Currently on prednisone regimen at time of Screening and anticipated to be tapered to a stable dose of prednisone of no more than 20 mg/day for at least 14 days prior to Day 1
• Has systolic blood pressure (BP) \<160 mmHg or diastolic BP \<100 mmHg after 5 minutes of rest at Screening;
• Is willing and able to provide written informed consent prior to Screening;
• Female subjects of non-childbearing potential must be either surgically sterile (hysterectomy, bilateral tubal ligation, salpingectomy, and/or bilateral oophorectomy at least 26 weeks before the Screening Visit) or postmenopausal, defined as spontaneous amenorrhea for at least 2 years, with follicle-stimulating hormone in the postmenopausal range at Screening, based on the central laboratory's ranges;
• Female subjects of childbearing potential (ie, ovulating, premenopausal, or not surgically sterile) and all male subjects must use a medically accepted, highly effective contraceptive regimen during their participation in the study and for 125 days (4 months) after the last administration of study drug.
• Male subjects must agree to abstain from sperm donation through 125 days (4 months) after administration of the last dose of study drug.

You may not qualify if:

• Has an estimated glomerular filtration rate (eGFR) \<60 mL/min/1.73 m2 at Screening utilizing the Chronic Kidney DiseaseEpidemiology Collaboration formula confirmed by the central laboratory;
• Has an absolute neutrophil count \<1.5 x 10/L;
• Has a white blood cell count \<3.0 x 10/L;
• Has secondary causes of MCD or FSGS (eg, malignancy, hepatitis B or C, human immunodeficiency virus \[HIV\], systemic lupus erythematosus \[SLE\], or other autoimmune diseases \[eg, thyroiditis\], drug-induced);
• Has a diagnosis or history of SLE (including non renal disease);
• Has type 1 or 2 diabetes mellitus;
• Has an acute, chronic, or latent infection, including tuberculosis, hepatitis, HIV, or chronic urinary tract infection.
