Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Screening eGFR ≥15.0 and ≤60.0 mL/min/1.73 m2;
  • A history of type 2 diabetes; diagnosis should have been made at ≥ 30 years of age (if diabetes developed at a younger age, a fasting C-peptide level must be ≥ 0.1 ng/mL to confirm type 2 diabetes);
  • Male or female patients at least 18 years of age;
  • Treatment with an angiotensin converting enzyme (ACE) inhibitor and/or an angiotensin II receptor blocker (ARB) for at least 6 weeks prior to Study Day 1. The dosage of ACE inhibitor and/or ARB must be stable for 2 weeks prior to and/or during screening (i.e., no change in dosage or medication). Patients not taking an ACE inhibitor and/or ARB, or taking an ACE inhibitor and/or ARB at levels below the goal dose set by K/DOQI guidelines must have a documented medical contraindication (e.g., hyperkalemia, hypotension), which the investigator must provide and discuss with a medical monitor prior to Study Day 1. Patients not taking an ACE inhibitor and/or ARB because of a medical contraindication must have discontinued treatment at least 8 weeks prior to Study Day 1;
  • Mean systolic blood pressure (SBP) ≤160 mmHg and ≥105 mmHg and mean diastolic blood pressure (DBP) ≤90 mmHg during screening; both mean SBP and mean DBP (determined as the average of three readings) must be within the described range during the screening period;
  • Willing to practice methods of birth control (both males who have partners of childbearing potential and females of childbearing potential) during screening, while taking study drug and for at least 30 days after the last dose of study drug is ingested;

  • Female patients who are pregnant, intend to become pregnant during the study, or are nursing;
  • BMI < 18.5 kg/m2;
  • Known hypersensitivity to any component of the study drug;
  • Current history of drug or alcohol abuse, as assessed by the investigator;
  • Clinically significant infection requiring intravenous administration of antibiotics or hospitalization within 6 weeks prior to or during the screening period;
  • Hepatitis B surface antigen positive;
  • Diagnosis or treatment of a malignancy in the past 5 years, excluding non-melanoma skin cancer and carcinoma in situ of the cervix, or a condition highly likely to transform into a malignancy during the course of the study;
  • A clinical condition that, in the judgment of the investigator, could potentially pose a health risk to the patient while involved in the study;
  • Participation in a clinical study involving any intervention within 30 days prior to Study Day 1, concurrent participation in such a study, or participation in a prior clinical study involving bardoxolone methyl in any form;

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Bardoxolone Methyl in people with Renal Insufficiency, Chronic and Diabetes Mellitus, Type 2, run by Biogen.

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 9 inclusion and 29 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: withdrawn, as of the sponsor's last update on 29 May 2025. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Change in renal perfusion (time frame: 20 weeks). 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 29 May 2025.
