[米国FDAによって承認またはクリアされていないデバイスの試験] (APPRECIATE)
The purpose of this study is to assess the efficacy and safety of AZD2373 in participants diagnosed with APOL1-Mediated Kidney Disease (AMKD) who are homozygotes or compound heterozygotes for APOL1 high-risk genotypes (G1 and G2). The primary hypothesis to be evaluated is that AZD2373, compared with placebo, will result in a greater reduction in UACR as assessed by the relative change from Baseline in UACR at Week 30.

条件
詳細な説明
This is a Phase 2b study to assess efficacy and safety of AZD2373 involving 3 study treatment arms in Part A and 2 study treatment arms in Part B where participants and study personnel including study investigators are blinded to the assigned treatment.
Participants with 300 mg/g or greater UACR and eGFR ≥ 25mL/min/1.73m2 will be recruited into the study. Participants on kidney replacement therapy (dialysis or kidney transplant) or any other organ transplant will be excluded.
The study will have Part A and Part B. Part A (n = 96) will have a 1:1:1 randomization of participants to subgroups receiving weekly subcutaneous injections of 50 mg AZD2373, 150 mg AZD2373, and placebo. Part B (n = 40) will have a 4:1 randomization of participants to subgroups receiving every other week subcutaneous injections of 150 mg or placebo. Part B will begin after Part A is completely enrolled.
Both Part A and Part B will have same participant criteria and schedules. The SoA and visit schedule will not change for Part B.
All participants will remain in the study on treatment until the last participant has completed 30 weeks of treatment. The treatment duration will be up to minimum of 30 weeks of study treatment.
All participants will have the opportunity to enter the OLE study.

History or serologic evidence of autoimmune-mediated glomerular disease including but not limited to: lupus nephritis (positive lupus serology), ANCA associated vasculitis (antineutrophil cytoplasmic antibody), membranous nephropathy (anti-phospholipase A2 receptor antibody or other autoantibody associated with membranous nephropathy), anti-GBM disease (anti-GBM antibody), or IgA nephropathy.
