A Study to Investigate the Safety, Tolerability, and Preliminary Efficacy With AION-301 Administered by Intravenous Infusion Compared With Placebo Administered by Intravenous Infusion Investigational Intervention in Participants Aged 35 to 75 Years of Age With Chronic Kidney Disease (CKD)

Recruiting now · Phase 1/Phase 2 · Has a placebo group

Conditions studied: Chronic Kidney Disease Stage 3

In brief

The goal of this clinical trial is to learn about the safety (good or bad) of giving two AION-301 intravenous (IV) infusions, in adults with Stage 3 Chronic Kidney Disease (CKD). It will also help to learn if AION-301 reduces the symptoms of CKD and/or progression. The main questions it aims to answer are: * Do participants have medical problems (adverse events) after receiving two infusions of AION-301? * Do participants feel better (have reduced and/or delayed CKD symptoms)? * To learn about how AION-301 works in participants with CKD? Researchers will compare AION-301 to a placebo (a look-alike substance that contains no drug) to see if AION-301 works to treat Stage 3 CKD. Participants will: * Receive two infusions of AION-301 or placebo on two separate days (Day 0 and Day 4). * Receive oral vitamins at the clinic and to take at home for 90 days. * Visit the clinic for a minimum of 9 times, over 6 months for checkups and tests, but could be up to 12 times, over 24 months for checkups and tests.

You may qualify if…

Participants are eligible to be included in the study only if all of the following criteria apply:
Patient is able to communicate well with the investigator, is capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol, understands all requirements of the study, and understands and signs the written ICF before any study-specific procedure.
Willing and able to comply with the scheduled visits and treatment plan.
Either biological sex
Participant must be 35 to 75 years of age inclusive, at the time of signing the informed consent.
Diagnosis of CKD stage 3, G3 (a and b): persistent eGFR between 30 and 59 mL/min/1.73 m² (at least 2 measures within that range in the preceding 3 months, including the one at screening visit), and persistent increased Albuminuria (at least 2 measures within 3 months, including 1 before screening and 1 at screening (criterion for increased Albuminuria at screening: ≥2 out of 3 repeat daily early morning samples at screening) (UACR ≥ 200 mg/g and < than 5000 mg/g)
Treatment with maximum labelled or tolerated dose of a renin-angiotensin-aldosterone system (RAAS) blocking agent including an angiotensin converting enzyme (ACE) inhibitor or an angiotensin II receptor blocker (ARB), and SGLT2 inhibitors (SGLT2i) unless such treatment is contraindicated or not tolerated*. Treatment dose must be stable for at least 3 months prior to the date of the screening. If a patient is on treatment with GLP-1 receptor agonist, he/she should be on a stable dose for at least 3 months before screening.
Participants who are documented to be unable to take ACE inhibitors or ARBs or SGLT2i will be allowed to participate.
Female subjects must not be breastfeeding and must have no intention to become pregnant during the study, and she will be required to use at least two FDA approved birth control during the study. The FDA-approved and cleared methods for birth control are listed below:
Permanent Sterilization
Long-Acting Reversible Contraceptives (LARC)
Contraceptive Injection
Short-Acting Hormonal Methods
Barrier Methods
Emergency Contraception
Any male subject must agree to use contraceptives and not donate sperm during the study.
Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.

You may not qualify if…

On medications such as immunosuppressant, monoclonal antibodies, anabolic steroids, at the time of screening or in the previous 6 months and/or illicit drugs.
History of alcohol abuse or cigarette smoking in the previous 6 months.
Pregnancy or breast feeding at the time of screening, or with intention to become pregnant or breast-feeding during the course of the study, including the follow-up period.
History of liver disease, ALT and AST ≥3 x ULN, positive serology for Hepatitis B or Hepatitis C, HIV.
