Официальное название

Phase 2b Multicentre, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Dose-Ranging Study to Assess the Efficacy, Safety, and Tolerability of AZD2373 in Participants With APOL1-Mediated Kidney Disease (APPRECIATE)

Обзор

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.

Подробное описание

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.

Устройство APOL1 Genotyping Clinical Trial Assay
The APOL1 Genotyping Clinical Trial Assay, an investigational use only qualitative Polymerase Chain Reaction invitro diagnostic assay, discriminates between the rs73885319 G1(S342G) and rs71785313 G2 genotypes within the APOL1 gene from DNA extracted from whole blood.

Критерии участия

Критерии включения

Age: Male and female participants of African descent (including, but not limited to, Black, Black African, Black Caribbean, African American, Afro-Caribbean, Afro-Latino, West African, Mixed Black backgrounds, or other self-identified African diaspora heritage) aged 18 to 70 years, inclusive at the time of informed consent.
Participants who have high-risk APOL1 genotype (G1/G1; G1/G2; G2/G2). The screening period can be extended if there are delays related to the shipment, handling, or processing of genotype results.
A geometric mean UACR ≥ 300 mg/g calculated based on the mean of readings taken from 3 FMV urine samples collected on 3 consecutive days. Since the mean will be assessed for eligibility, any of the 3 readings may fall below 300 mg/g.
eGFR ≥ 25 mL/min/1.73m2.
Contraceptive use by males or females should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol.
