IgA Nephropathy
Conditions
Brief summary
Multicenter study designed to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of BION-1301 in healthy volunteers and adults with IgA Nephropathy (IgAN).
Detailed description
This is a Phase 1/2 study of BION-1301, a first-in-class humanized IgG4 anti-a proliferation-inducing ligand (APRIL) monoclonal antibody. The study was conducted in four parts. Part 1: double-blind, randomized, placebo-controlled, single ascending dose (SAD) in healthy volunteers (HVs). Part 2: double-blind, randomized, placebo-controlled multiple ascending dose (MAD) in HVs. Part 3: Open-label, multiple dose (MD) in participants with IgAN. Part 4: Retreatment period The study planned to enroll up to 40 participants with IgAN.
Interventions
A single IV infusion infusion of BION-1301 at doses ranging from 10 to 1350 mg, administered once
A single IV infusion of placebo
Part 2: Multiple IV infusions of BION 1301 administered every 2 weeks (Q2W) at doses of 50 mg, 150 mg or 450 mg for up to 3 doses. Part 3: Repeated dosing of BION 1301: 450 mg IV Q2W for ≥24 weeks followed by 600 mg SC Q2W, or 600 mg SC Q2W throughout.
Multiple IV infusions of placebo administered every 2 weeks for up to 3 doses

Study design
Masking description
Parts 1 and 2 were performed in a double-blind manner, for clinical research personnel interacting with study participants. An unblinded pharmacist prepared the doses of investigational study drugs.
Intervention model description
Part 1 (SAD-HV) is a randomized, placebo-controlled single ascending dose design in HVs. Part 2 (MAD-HV): is a randomized, placebo-controlled multiple ascending dose design in HVs. Part 3 (MD-IgAN) is an open-label multiple dose design in participants with IgAN. Part 4 (IgAN) is open-label retreatment for Part 3 participants.
