Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Bardoxolone methyl oral capsule
Treatment: Drugs - Placebo oral capsule

Experimental: Maximum bardoxolone methyl dose of 20 mg - Patients randomized to receive bardoxolone methyl with a baseline ACR less than or equal to 300 mg/g will be titrated to a maximum dose of 20 mg. Patients will begin once-daily dosing with bardoxolone methyl capsules at 5 mg and will dose escalate to 10 mg at Week 2 and 20 mg at Week 4.

Patients will continue to receive study drug through Week 100, and will not receive study drug during a 12-week off-treatment period between Weeks 100 and 112.

Experimental: Maximum bardoxolone methyl dose 30 mg - Patients randomized to receive bardoxolone methyl with a baseline ACR greater than 300 mg/g will be titrated to a maximum dose of 30 mg. Patients will begin once-daily dosing with bardoxolone methyl capsules at 5 mg and will dose escalate to 10 mg at Week 2, 20 mg at Week 4 and 30 mg at Week 6.

Patients will continue to receive study drug through Week 100, and will not receive study drug during a 12-week off-treatment period between Weeks 100 and 112.

Placebo comparator: Placebo - Patients randomized to placebo will remain on placebo capsules throughout the study, undergoing sham titration.

Patients will continue to receive placebo capsules through Week 100, and will not receive capsules during a 12-week off-treatment period between Weeks 100 and 112.


Treatment: Drugs: Bardoxolone methyl oral capsule
Bardoxolone methyl capsules dose escalated from 5 mg to a maximum of 20 or 30 mg, depending on baseline proteinuria status.

Treatment: Drugs: Placebo oral capsule

Eligibility
Key inclusion criteria
* Male and female patients 12 = age = 70 upon study consent;
* Diagnosis of ADPKD by modified Pei-Ravine criteria (for adults 18= age =70 years): 1) at least 3 cysts per kidney by sonography or at least 5 cysts by CT or MRI with family history of ADPKD or 2) at least 10 cysts per kidney by any radiologic method and exclusion of other cystic kidney diseases if without family history;

1) Patients with either screening eGFR = 60 to = 90 mL/min/1.73 m2 or age 56 to 70 years, must have evidence of ADPKD progression (i.e., eGFR decline of = 2.0 mL/min/1.73 m2 per year, based on historical eGFR data and medical monitor discretion); 2)The two eGFR values collected at Screen A and Screen B visits used to determine eligibility must have a percent difference = 25%;
* Albumin to creatinine ratio (ACR) = 2500 mg/g at Screen B visit;
* Systolic blood pressure = 140 mmHg and diastolic blood pressure = 90 mmHg at Screen A or B visit after a period of rest.
Minimum age
12 Years
Maximum age
