Conditions

Rapidly progressive glomerulonephritis

Brief summary

The primary endpoint for this study is the safety and tolerability of ALE.F02 when administered as a continuous IV infusion in patients with RPGN attributed to AAV. Safety endpoints are the following: - All AEs; - All SAEs; - Hematology and clinical chemistry analyte assessments; - Serum lipids; - Antidrug antibodies (ADAs); and - ECGs.

Detailed description

1. The key secondary endpoint for this study is the change in mean eGFR from baseline to Week 24/EOT for recipients of ALE.F02 compared to placebo., 2. Change in mean urine protein to creatinine ratio (UPCR) AUC from baseline to Week 24/EOT and Week 52/EOS for recipients of ALE.F02 compared to placebo;, 3. Time to stable proteinuria (≤0.5 g/day for ≥14 days) during the Treatment Period for recipients of ALE.F02 compared to placebo;, 4. Time to stable hematuria (≤5 RBCs/high-power field for ≥14 days) during the Treatment Period for recipients of ALE.F02 compared to placebo;, 5. Incidence of RRT at any time during the study for recipients of ALE.F02 compared to placebo; and, 6. Total glucocorticoid and immunosuppressive exposure at Week 24/EOT and Week 52/EOS for recipients of ALE.F02 compared to placebo.
