Brief Summary:

Funding Source - FDA OOPD

Pioglitazone is currently used in clinical practice to treat diabetes and this study will examine the potential use of a low dose of the same drug for the treatment of polycystic kidney disease. The purpose of this study is to determine whether the diabetes drug pioglitazone (Actos) is a safe and effective treatment of autosomal dominant polycystic kidney disease when treated in its early stages. Pioglitazone is approved by the FDA for the treatment of diabetes. Pre-clinical models of polycystic kidney disease have shown that low dose treatment with pioglitazone decreases the growth of the cysts. The studies also suggest that effective pioglitazone dosing for polycystic kidney disease may be lower than that used to treat diabetes. The purpose of this study is to see if pioglitazone might slow cyst disease in humans.

Condition or disease Intervention/treatment Phase
Polycystic Kidney Disease Drug: Pioglitazone Drug: Placebo Phase 2

Detailed Description:
Patients will be randomize to placebo or 15 mg pioglitazone for 12 months, and then be crossed over to the other arm. Patients will undergo MRI of the liver and kidney and MRspectroscopy of the lumbar spine (if they choose as this is ancillary study) three times during the study. Assessments will be every 3 months and include blood work, blood pressure, and body water assessments.

Arm Intervention/treatment
Placebo Comparator: Placebo Arm
Subject will be on placebo
Drug: Placebo

Active Comparator: Pioglitazone Arm
Subject will be on pioglitazone
Drug: Pioglitazone
Other Name: Actos

Primary Outcome Measures :
  1. Safety: Total Body Water [ Time Frame: average of 4 measures in each 12 month arm ]
    Bioimpedance analysis (BIA)(Ohms); Increase in BIA in Ohms indicates a decrease in total body water

  2. Efficacy: Percent Change in Total Kidney Volume [ Time Frame: Baseline, end of year 1, and end of year 2 ]
    Change in total kidney volume by Magnetic Resonance Imaging (MRI) from beginning to end of the 12 months

Secondary Outcome Measures :
  1. Safety: Hypoglycemia [ Time Frame: measured quarterly for 12 months in pioglitazone and same in placebo ]
    number of patients with blood sugar < 70 mg/dl

  2. Safety: Elevated Liver Function Tests [ Time Frame: measured quarterly over 12 months for each arm ]
    Number of patients with elevated liver test (ALT or AST) > 2 times upper limit of normal

  3. Efficacy: Glomerular Filtration Rate [ Time Frame: average of 4 values over 12 months ]
    average estimated glomerular filtration rate by chronic kidney disease (CKD) epidemiologic (epi) formula measured quarterly

  4. Efficacy Blood Pressure [ Time Frame: average of 4 measures over 12 months ]
    mean systolic and diastolic blood pressure

  5. Bone Marrow Fat [ Time Frame: Baseline, end of year 1, and end of year 2 ]
    We will assess change in bone marrow fat by MR spectroscopy as an ancillary study to be done at the same time as MRI; will not be done due to person leaving institution.
