Assessment method [1]

Adverse event (AE): any untoward medical occurrence in a participant who received study drug and did not necessarily had to have a causal relationship with the treatment. Serious adverse event (SAE) was any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was a medically important event. TEAEs: AEs with onset after the first dose of investigational medicinal product (IMP) or existing AEs that worsened during TEAE Period (for DB Period: from first IMP administration up to first administration in OLE period for participant who entered OLE period; and up to 7 days post last IMP administration for participant not continuing OLE period; for open-label: time from 1st IMP administration in open-label to last IMP administration+ 10 weeks).

Timepoint [1]

DB: from 1st dose of IMP upto 1st dose of IMP in OLE for participant who entered OLE (Week 48); up to 7 days post last dose for participant not continuing to OLE (Week 49); OLE:1st dose of IMP (at Week 48) in OLE upto 10 weeks post last dose (Week 106)

Primary outcome [2]

DB Period: Annualized Change From Baseline in Estimated Glomerular Filtration Rate (eGFR) at Week 48

Assessment method [2]

Annualized change in eGFR was calculated using Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) Creatinine Equation (for participants with age greater than 16 years) as: eGFR=142\*min(Scr/K, 1)a\*max(Scr/K, 1)\^-1.200\*0.9938\^Age\*1.012 \[if female\], where Scr = serum creatinine in milligrams per deciliter (mg/dL), K = 0.7 for females (F) and 0.9 for males (M), a = -0.241(F) and -0.302(M); age=years, calculated at time of creatinine measurement. eGFR measurements collected from baseline to Week 48 were the response variable and included fixed effects of treatment (lademirsen or placebo), screening eGFR stratification factor (less than \[\<\]60 versus greater than or equal to \[\>=\]60 milliliters per minute per 1.73 meters squared \[mL/min/1.73 m\^2\]), time, and treatment-by-time interaction. Least square (LS) mean and standard error (SE) estimated by linear mixed effect model.

Timepoint [2]

Baseline, Week 48

Secondary outcome [1]

DB Period: Absolute Change From Baseline in eGFR Values at Week 24 and 48

Assessment method [1]

eGFR was used to measure level of kidney function and determine the stage of kidney disease. eGFR was calculated using CKD-EPI Creatinine Equation as: eGFR =142\*min (Scr/K, 1) a\*max (Scr/K, 1)\^-1.200\*0.9938\^Age\*1.012 \[if female\], where Scr was serum creatinine in mg/dL, K is 0.7 for females and 0.9 for males, a was -0.241 for females and -0.302 for males. Unit of age was years, calculated to reflect the age at the time when creatinine was measured.
