Who can take part
You may be able to join if
- Male and female subjects aged 18 and older at the time of signing the ICF prior to initiation of any study specific activities/procedures.
- Open Label Extension - Subjects from the double-blind portion of study who have completed treatment throguh Week 132 and completed the Week 136 visit. Note: Subjects who were randomized to the non-SGLT2i stratum in the double-blind portion of the study may start SGLT2i during the OL extension
- Open Label Extension - Subjects entering the OL extension must enroll and have their OLBaseline visit within 14 days of Week 136 (OL Screening visit). Note: If enrollment in the OL extension was not possible due to administrative delays, patients who have completed the EOS visit in the double-blind portion of the study may be able to enroll in the open-label extension if less than 90 days have passed since their EOS visit after approval by Sponsor's Medical Monitor. If enrollment in the OL extension is > 30 days after Week 136, the patient must repeat the Week 136 laboratory assessments to confirm eligibility.
- Open Label Extension - All fertile men and WOCBP who engage in heterosexual intercourse must be willing to abide with highly effective forms of contraception, as specified in the protocol, throughout the study and for 1 month afterward. In WOCBP, use of contraceptive agents must have been continued after completing the double-blind portion of the study.
- Biopsy-proven IgAN that, in the opinion of the Investigator, is not due to secondary causes. Biopsy could have occurred at any point in time prior to study. A diagnostic report must be available for review by the Sponsor or designee.
- Receiving a maximally tolerated and optimized dose of a RAS inhibitor that has been stable for at least 12 weeks prior to screening. Investigator discretion should be used in determining maximally tolerated and optimized dose. Subjects who are intolerant to RAS inhibitors are eligible but will not exceed ~5% of total population randomized (applicable only to non- SGLT2i stratum)
You likely can't join if
- Concurrent diagnosis of another cause of chronic kidney disease including diabetic kidney disease or another primary glomerulopathy.
- Clinical suspicion of rapidly progressive glomerulonephritis (RPGN) based on KDIGO guidelines or clinical suspicion of Henoch-Schonlein Purpura (IgA vasculitis).
- Clinical diagnosis of nephrotic syndrome.
- BNP value of > 200 pg/mL at screening.
- Platelet count <80,000 per μL at screening.
- History of organ transplantation (subjects with history of corneal transplant are not excluded).
