Inclusion Criteria

•Male and female patients = 18 years of age with an eGFR level and biopsy-confirmed IgA nephropathy as follows:
•For patients eGFR* = 45ml/min/1.73m2, a qualifying biopsy performed within the last 5 years is required.
•For patients with eGFR* 30 to <45ml/min/1.73m2 a qualifying biopsy performed within 2 years with < 50% tubulointerstitial fibrosis is required.
• For patients with eGFR* 20 to <30ml/min/1.73m2,a qualifying biopsy performed at any time.
In all cases, if a historical biopsy is not available, one may be performed during screening. *eGFR calculated using the CKD-EPI formula (or modified MDRD formula according to specific ethnic groups and local practice guidelines)
•Proteinuria due to primary diagnosis of IgA nephropathy as assessed at screening by UPCR =1 g/g (113 mg/mmol) sampled from FMV or 24h urine collection, as well as at the completion of the run-in period by UPCR =1 g/g (113 mg/mmol) calculated as the mean of two 24h urine collections obtained within 14 days of each other at baseline.
•Vaccination against Neisseria meningitidis infection is required prior to the start of study treatment. If the patient has not been previously vaccinated, or if a booster is required, vaccine should be given according to local regulations at least 2 weeks prior to first study drug administration. If study treatment has to start earlier than 2 weeks post vaccination, prophylactic antibiotic treatment should be initiated.
•If not previously vaccinated, vaccination against Streptococcus pneumoniae and Haemophilus influenzae infections should be given, if available and according to local regulations, at least 2 weeks prior to first study drug administration. If study treatment has to start earlier than 2 weeks post vaccination, prophylactic antibiotic treatment should be initiated.
•All patients must have been on supportive care including stable dose regimen of ACEi or ARB at either the locally approved maximal daily dose or the maximally tolerated dose (per investigators' judgment) for at least 90 days before first study drug administration. In addition, if patients are taking diuretics or other antihypertensive therapy, or other background medication for IgAN, the doses should also be stabilized for at least 90 days prior to the first dosing of study treatment.

Other protocol-defined inclusion criteria may apply.

•Prior use of LNP023 or prior enrollment in any other LNP023 clinical trial where study drug was taken, including matching placebo
•History of recurrent invasive infections caused by encapsulated organisms, such as meningococcus and pneumococcus.
