A Phase 2 Trial of the Safety and Efficacy of Bardoxolone Methyl in Patients With Rare Chronic Kidney Diseases - PHOENIX
United States103 participantsStarted 2017-12-26
Plain-language summary
This multi-center, open-label Phase 2 trial will study the safety, tolerability, and efficacy of bardoxolone methyl in qualified patients with the following rare chronic kidney diseases (CKD): CKD associated with type 1 diabetes (T1D), IgA nephropathy (IgAN), focal segmental glomerulosclerosis (FSGS), and autosomal dominant polycystic kidney disease (ADPKD). Patients will be enrolled in disease specific cohorts within the trial, and effectiveness of bardoxolone methyl in treating CKD will be assessed separately by cohort for each rare CKD.
All patients in the study will follow the same visit and assessment schedule. Following randomization on Day 1, patients will be scheduled to be assessed during treatment at Weeks 1, 2, 4, 6, 8, and 12, and by telephone contact on Days 3, 10, 21, 31, 38, and 45. Patients will also be scheduled to be assessed at an in-person follow-up visit at Week 16, four weeks after the end of treatment.

Inclusion Criteria:
* Male and female patients 18 ≤ age ≤ 65 upon study consent;
* Screening eGFR (average of Screen A and Screen B eGFR values) ≥ 30 and ≤ 90 mL/min/1.73 m2. 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;
* If receiving an angiotensin-converting enzyme (ACE) inhibitor and/or an angiotensin II receptor blocker (ARB), patients should be prescribed the maximally tolerated labeled daily dose (MTLDD) for at least 6 weeks prior to the Screen A visit;
* For patients enrolling in T1D Cohort: Diagnosis of type 1 diabetes confirmed by fasting C-peptide level. Diagnosis must have been made ≤ 35 years of age; and prescribed stable dose of insulin to maintain adequate glucose control for at least 6 months prior to the Screen A visit;
* For patients enrolling in IgAN Cohort: Biopsy-confirmed IgA nephropathy;
* For patients enrolling in FSGS Cohort: Biopsy-confirmed FSGS that is not due to known secondary causes including morbid obesity, decreased renal mass, viral infections, drug-induced nephrotoxicity, or prior history of vasculitis;
* For patients enrolling in ADPKD Cohort: Genetic confirmation of PKD1 mutation;
* Adequate bone marrow reserve and organ function at the Screen A visit as follows: Hematologic: Absolute neutrophil count \> 1.5 x 109/L, platelets \> 100 x 109/L, hemoglobin (Hgb) ≥ 9 g/dL; and Hepatic: Total bi…
