What this trial studies

This clinical trial aims to evaluate the safety, tolerability, and preliminary efficacy of AION-301 administered via intravenous infusion in adults aged 35 to 75 with Stage 3 Chronic Kidney Disease (CKD). Participants will receive two infusions of AION-301 or a placebo on separate days, along with oral vitamins for 90 days. The study will monitor adverse events and assess improvements in CKD symptoms over a period of up to 24 months through regular clinic visits and tests.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 35 to 75 with a diagnosis of Stage 3 Chronic Kidney Disease.

Not a fit: Patients with CKD stages other than Stage 3 or those outside the age range of 35 to 75 may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could potentially slow the progression of Chronic Kidney Disease and improve patient symptoms.

How similar studies have performed: While there have been studies on CKD treatments, the specific approach using AION-301 is novel and has not been extensively tested in this context.

Eligibility criteria

Inclusion Criteria:

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)

  * 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.
