New drug aims to plug leaky kidneys in APOL1 disease
NCT ID NCT06824987
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests an injectable drug called AZD2373 in 136 people with APOL1-mediated kidney disease, a genetic condition that mainly affects people of African descent. The goal is to see if the drug can reduce protein leakage into urine, a sign of kidney damage. Participants will receive either AZD2373 or a placebo for 30 weeks, and researchers will measure changes in urine protein levels.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AZD2373 (an injectable drug)
- What this could lead to
- If it works, this could point toward a treatment that slows kidney damage in people with APOL1-related kidney disease, potentially delaying the need for dialysis or transplant.
- What could go wrong
- This is an early Phase 2b trial with only 136 participants, so results may not apply to everyone. The drug may not reduce protein in urine enough, or could have side effects not yet seen.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * 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. Exclusion Criteria: * Participants with diagnosis of Type 1 diabetes mellitus. * Body Mass Index \> 45 kg/m2. * SBP \> 180 mmHg/DBP \> 110 mmHg (measured when the participant is considered to be at steady state, and preferably when they have taken their BP medications that same day). * QTcF \> 470 ms, except participants with bundle branch block who should excluded if QTcF\> 480 ms. * Acute coronary syndrome/Acute myocardial infraction with or without any coronary intervention within 6 months. * Transient ischaemic attack/ stroke within 3 months. * High grade (second to third) degree AV block or clinically significant sinus node dysfunction untreated with pacemaker. * A history of ventricular arrhythmias requiring treatment. * Participants with Type 2 diabetes mellitus must be excluded if ANY of the following conditions are present: 1. Current or past use of insulin for more than 3 months and/or any maintenance therapy with insulin within 2 months of screening. 2. Screening Haemoglobin A1c \> 8.0% 3. Receiving more than one anti-hyperglycaemic agent (excluding SGLT inhibitors and GLP-1 receptor agonists is permitted if prescribed for a purpose other than glycaemic control which can be taken in addition to one other anti-hyperglycaemic agent). * Participant on kidney replacement therapy (dialysis or kidney transplant) or any other organ transplant. * 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. * Another underlying cause of kidney disease that is not associated with APOL1, including but not limited to polycystic kidney disease or, congenital anomalies of the kidney and urinary tract. * History of a diagnosed coagulopathy, a major unexplained bleeding event, or other high-risk bleeding diathesis. * A history of trypanosomiasis or leishmaniasis.
