Brief summary

This is a phase II, open label, experimental medicine study to evaluate the efficacy, safety and mechanism of action of belimumab in subjects with antiphospholipase A2 receptor (PLA2R) autoantibody positive idiopathic membranous glomerulonephropathy (IMGN), and to profile the relationship between biomarkers, autoantibody status and clinical response. 10 milligrams per kilogram (mg/kg) belimumab intravenous (IV) will be administered at weeks 0, 2, and then every 4 weeks, over a 24-week treatment period in subjects with anti-PLA2R antibody positive IMGN followed by a further long term treatment period until subjects reach remission of proteinuria, up to a maximum of 2 years total treatment. All subjects will receive background supportive therapy throughout the study. The dosing frequency will be adjusted to every 2 weeks if the subject's proteinuria as assessed by urinary protein creatinine ratio (PCR) is greater than 1000 milligrams per millimole (mg/mmol) \[greater than 10 grams(g)/24 hours (h)\], to compensate for loss of belimumab in the urine. Effects on mechanistic markers will be measured by the level of proteinuria, levels of anti-PLA2R antibodies, and various other measures of kidney function. These will be compared to historical data. The pharmacokinetics of belimumab will be measured to confirm dosing in heavily proteinuric subjects. Pharmacodynamic (PD) markers, biomarkers and Quality of Life(QoL) in IMGN subjects will also be investigated. Safety will be assessed by adverse events (AE), clinical laboratory evaluations, and vital signs.

Recruitment details

Eligible participants were recruited from July 2012 until March 2014, into this 2 part study of a initial treatment phase, a long term treatment phase, and then followed up for a further 6 months. Results have previously been presented for the initial treatment phase, up to the Week 28 and are now presented for the completed study.

Pre-assignment details

Screening occurred within 35 days and no less than 14 days before the first scheduled study treatment dose. Total 21 participants were screened; 14 were randomized and entered the initial treatment phase while 11 participants entered the long-term treatment phase. Common reasons for screen failures were insufficient, or improvements in proteinuria.

Change From Baseline in Anti-phospholipase A2 Receptor (PLA2R) Autoantibody Titers at Week 28

PLA2R autoantibody titers in serum were analyzed at Baseline and Week 28 by means of a validated anti- PLA2R enzyme linked immunosorbent assay (ELISA) from EuroImmun. Baseline is defined as the Day 0 value and change from Baseline was calculated as ratio to Baseline by dividing the Week 28 values with the Baseline values. Ratio to Baseline: Estimated value = 0.27, 2-sided 95% CI=0.12 to 0.58. The geometric mean method was used to calculate the CI.

Number of Participants With Abnormal Clinical Chemistry and Hematology Values

Blood samples were collected from participants for evaluation of clinical chemistry and hematology parameters. The clinical chemistry parameters included albumin, alkaline phosphatase (alk.phosph.), alanine amino transferase (ALT), aspartate amino transferase (AST), total and direct bilirubin, calcium, cholesterol, chloride, carbon dioxide, creatinine, gamma glutamyl transferase (GGT), glucose, potassium, lactate dehydrogenase (LD), magnesium, sodium, phosphorus, total protein, blood urea nitrogen (BUN) and uric acid. The hematology parameters included basophils, eosinophil, hemoglobin, hematocrit, lymphocytes, monocytes, total neutrophils, platelets, red blood cells (RBC) count and white blood cells (WBC) count. Participants were counted in the category that their value changes to (low or high) for the specific time points. Only those participants with data available at the specified data points were analyzed (represented by n=X in the category titles).

Number of Participants With Complete or Partial Remission

Complete remission is defined as PCR \<30 mg/mmol (proteinuria \<0.3grams \[g\]/24 h) with no worsening in renal function (estimated glomerular filtration rate \[eGFR\] reduction from Baseline \<15 percent). Partial remission is defined as PCR \<350 mg/mmol (proteinuria \<3.5 g/24 h) but \>= 30 mg/mmol (proteinuria \>= 0.3g/24h) and decrease of \>50 percent from Day 0 Baseline, together with no consistent worsening in renal function (eGFR reduction from Baseline \<15percent). Only those participants available at the specified time points were analyzed (represented by n=X in category titles).

Trough concentration (Cmin) samples collected on the specified days are being used to assess attainment whether there was sufficient belimumab despite it being lost in the urine from the proteinuria and to check if it improved as proteinuria resolved. Analysis was performed on pre-infusion samples at weeks 2,4,8,12,28,40,52,76 and the 4 week post last-dose.

Time frame: Baseline and up to 4 week post last dose

Summary of Total Amount of Urine Excreted Ae(0-24)

PK parameters from the urine concentration data: urine Ae(0-24) were assessed. 24 h urine collections for PK analysis were collected after the Day 0 and Weeks 12, 28, 52, 76 doses and at the 4 week post last dose visit. A population approach was undertaken to characterize the population PK parameters and associated variability of belimumab in nephrotic participants. The population approach could have provided derived clearance of belimumab for each participant after the first dose. The population PK analysis was conducted using nonlinear mixed-effect modeling (NONMEM) or appropriate nonlinear mixed-effect analysis software. Several samples were taken pre-dose at Day 0 and some at week 12 incorrectly which affects interpretation.

Time to Complete or Partial Remission

Time to complete or partial remission was estimated using the Kaplan-Meier method. Complete remission is defined as PCR \<30 mg/mmol (proteinuria \<0.3g/24 h) with no worsening in renal function (eGFR reduction from Baseline \<15 percent ). Partial remission is defined as PCR \<350 mg/mmol (proteinuria \<3.5 g/24 h) but \>= 30 mg/mmol (proteinuria \>= 0.3g/24h) and decrease of \>50 percent from Day 0 Baseline, together with no consistent worsening in renal function (eGFR reduction from Baseline \<15 percent). Only 1 participant reached complete remission. Hence, statistical analysis for complete remission was not performed.

Urine BLys Levels as a Ratio to Creatinine

B lymphocyte stimulator (BLyS) normalized by creatinine as a ratio of BLyS: creatinine. Free BLyS protein is being analyzed using an ELISA. Urine samples are being collected before treatment and after belimumab washout at Week 0 and Week 116/16 week follow-up visit. Only raw BLyS values available and unable to be assessed due to lack of comparison to a creatinine as a urine concentration marker.

Urine Membrane Attack Complex (MAC) Levels

Urine membrane attack complex was assayed quantitatively by ELISA method. Urine MAC samples were collected at Day 0 and Weeks 8, 28, 52, 76 and 4 week post last dose. Results were normalized using urine creatinine concentration to adjust for urine dilution. Endpoint was moved to 'Exploratory' in Protocol amendment 5 as risk of availability of functioning assay for urine membrane attack complex was noted. No assay was subsequently found and samples were not analyzed
