About this study

Official title: 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)

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.

Read the detailed description

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.

  3. Relative change in Urine Protein-Creatinine Ratio (UPCR)

    To assess the effect of AZD2373 versus placebo in reducing proteinuria

    Measured: From Baseline at the End of Treatment (Until the last participant completes Week 30)

  4. Proportion of participants achieving a 45% or greater reduction in Urine Albumin-Creatinine Ratio (UACR)

    To assess the proportion of participants achieving a 45% or greater Urine Albumin-Creatinine Ratio (UACR) reduction by treatment

    Measured: From Baseline at Week 30

  5. Proportion of participants achieving a 45% or greater reduction in Urine Albumin-Creatinine Ratio (UACR)

    To assess the proportion of participants achieving a 45% or greater Urine Albumin-Creatinine Ratio (UACR) reduction by treatment

    Measured: From Baseline at the End of Treatment (Until the last participant completes Week 30)

  6. eGFR slope

    To assess pooled AZD2373 doses versus placebo on eGFR change

    Measured: From Baseline at the End of Treatment (Until the last participant completes Week 30)

  7. Incidence of development of ADA and ADA titer (if participants are ADA-positive)

    To evaluate the immunogenicity of AZD2373

    Measured: During treatment (up to Week 30) and follow-up (up to 12 weeks)

  8. Plasma concentration

    To evaluate the PK of AZD2373

    Measured: From Baseline at the End of Treatment (Until the last participant completes Week 30)

  9. Adverse Events (AEs), Serious Adverse Events (SAEs), and Drug Adverse Events (DAEs).

    To assess the safety and tolerability of ranging doses of AZD2373. These events will be collected according to the timepoints specified in the schedule of assessments, starting from the time of signing the Informed Consent Form (ICF).

    Measured: From baseline at the End of Treatment (Until the last participant completes Week 30)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AZD2373-Arm 1, AZD2373-Arm 2 and APOL1 Genotyping Clinical Trial Assay in people with APOL1-Mediated Kidney Disease, run by AstraZeneca at 96 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 13 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 96 sites in United States, United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Relative change in Urine Albumin-Creatinine Ratio (UACR) (time frame: From Baseline at Week 30). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Oct 2026.
