This extended access study will assess the long-term safety and tolerability of bardoxolone methyl in qualified patients with chronic kidney disease (CKD) who previously participated in one of the qualifying clinical studies with bardoxolone methyl. Patients will remain in the study until bardoxolone methyl is available through commercial channels or until patient withdrawal, whichever is sooner.

Open to people ages 12 years and up

  • Patients who are participating (or who have participated) in qualifying studies and who have not been required to discontinue study treatment for protocol or safety reasons and who have completed required End-of-Treatment and/or Follow-up visits in a prior clinical study with bardoxolone methyl and who, according to the assessment of the investigator, have a potential positive benefit-risk assessment for participating in the trial.
  • Meets the following eligibility criteria based on assessments from the prior qualifying study (last on-treatment visit) or from a screening visit, if applicable:
    1. Not expected to reach end stage kidney disease (ESKD) or nephrotic syndrome within 12 weeks of study enrollment, in the investigator's judgement; subjects with eGFR <20 ml/min/1.73m2 should be discussed with the medical monitor before enrollment (e.g., such subjects with an average rate of eGFR decline > 1.0 ml/min/1.73m2 per month in the 3 months prior to eligibility assessment may not be eligible);
    2. BNP < 200 pg/mL at the last on-treatment visit in the prior qualifying study or at a new screening visit, if applicable;
    3. No occurrence of a cardiovascular serious adverse event in the prior qualifying study or in the interval between the end of the qualifying study and the screening visit, if applicable.
  • Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
  • Evidence of a personally signed and dated informed consent document (and assent form if necessary) indicating that the patient (or a legally acceptable representative) has been informed of all pertinent aspects of the study prior to initiation of any protocol-mandated procedures.

You CAN'T join if...

  • Participation in other investigational clinical studies involving interventional products being tested or used in a way different from the approved form or when used for an unapproved indication;
  • Patients who have an ongoing SAE from a clinical study that is assessed by the investigator as related to bardoxolone methyl;
  • Unwilling to practice acceptable methods of birth control (both males who have partners of childbearing potential and females of childbearing potential) while screening, taking study drug and 30 days after the last study drug dose;
  • Women who are pregnant or breastfeeding;
  • Patient is, in the opinion of the investigator, unable to comply with the requirements of the study protocol or is unsuitable for the study for any reason;
  • Known hypersensitivity to any component of the study drug.

Lead Scientist at UCSF

  • Meyeon Park, MD
    My research focuses on the early diagnosis of kidney hypoxia, injury, and disease and the influence of cardiovascular disease on kidney disease onset and progression. Clinically, I see patients with all manifestations of hypertension and kidney disease, with a special focus on patients with polycystic kidney disease.
