The purpose of the study is to learn about the safety and tolerability of setanaxib in subjects with Alport syndrome, when added to their standard of care treatment. The study will assess how safe setanaxib is when compared to placebo. Study participants will be asked if they are experiencing any side effects at each study visit. In addition, tests in blood, urine and other examinations will be used to look at the safety of setanaxib. The study will also measure how well setanaxib works in comparison to a placebo, by measuring urine protein and certain markers in the blood and urine. The concentration of setanaxib in the blood will also be measured throughout the course of the study.
Setanaxib is planned for use together with the current standard of care to hopefully provide additional therapeutic benefits by preserving kidney function.
The study will be conducted at multiple research sites in the UK, Spain, and Czech Republic. Eligible participants will be randomly assigned to receive either setanaxib or placebo. Setanaxib dose level will depend on age and all participants will receive their standard of care in addition to setanaxib or placebo. The study consists of a Screening period of up to 4 weeks, a 24-week Treatment period and a 4- week Follow-up period.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Male or female patients aged 12 to 50 years inclusive, at the time of informed consent/assent. For sites in the European Union: Male or female patients aged 18 to 50 years, inclusive, at the time of informed consent;
. Diagnosis of Alport syndrome by genetic testing (documented mutation in a gene associated with Alport syndrome \[ie, COL4A3, COL4A4, or COL4A5\]); Patients with a variant of uncertain significance should not be included in the study;
Exclusion criteria
. Weight ≥40 kg;
. Willing and able to give informed consent (and assent, where applicable), in accordance with local age requirements, and to comply with the requirements of the study;
. Female patients of childbearing potential must use a highly effective method of contraception to prevent pregnancy for ≥4 weeks before randomization and must agree to continue strict contraception (as specified in 5c) up to 90 days after the last dose of investigational medicinal product (IMP);
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Percentage of Patients With Serious Adverse Events (SAEs)
Timeframe: From informed consent up to 30 days post-final dose, up to 32 weeks
2
Percentage of Patients With Treatment-emergent Adverse Events of Special Interest (AESIs)
Timeframe: From informed consent up to 30 days post-final dose
. For the purposes of this study, women of childbearing potential (WOCBP) are defined as "fertile, following menarche and until becoming postmenopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy";
. Postmenopausal state is defined as no menses for 12 months without an alternative medical cause. In female patients who are not using hormonal contraception or hormonal replacement therapy but with suspected menopause and less than 12 months of amenorrhea, a high follicle-stimulating hormone level in the postmenopausal range will be required at Screening to confirm a postmenopausal state; and
. Highly effective contraception is defined as methods that can achieve a failure rate of less than 1% per year when used consistently and correctly. These methods include the following:
. Female patients of childbearing potential must have a negative serum pregnancy test at Screening and a negative urine pregnancy test at Visit 3 (after randomization and before dosing);
. Male patients with female partners of childbearing potential must be willing to use a condom and require their partner to use a highly effective contraceptive method (as defined in the list in inclusion criterion 5c). Female condom and male condom should not be used together. This requirement begins at the time of informed consent/assent and ends 90 days after receiving the last dose of IMP;
