Brief Description: This study is being conducted to evaluate the effects of Atrasentan on Renal Outcomes in Subjects with Type 2 Diabetes and Nephropathy.

The study will evaluate the effect of Atrasentan compared with placebo on time of doubling of serum creatinine or the onset of the end stage renal disease (ESRD) in subjects with type 2 diabetes and nephropathy who are treated with the maximum tolerated labeled daily dose of a Renin-Angiotensin System (RAS) inhibitor. In addition, the study will assess the effects of atrasentan compared with placebo on cardiovascular morbidity and mortality, urine albumin excretion, changes in estimated glomerular filtration rate (eGFR), as well as on the impact on quality of life in subjects with type 2 diabetes and nephropathy.

This study requires several visits to UAB. Some of the procedures are: electrocardiogram, collect: a blood sample, a urine sample and a DNA sample. Atrasentan or placebo will be provided at no cost for the subject participating in the study. Compensation is $50.00 per visit

Contact: Teresa Chacana, MSN, RN. Phone number: 205-934-7649, tchacana@uab.edu, fax 205-975-0814
Status of the trial: Enrolling by invitation

Brief Description: The goal of the CRISP Study is to conduct a prospective, longitudinal trial to evaluate the accuracy and validity of magnetic resonance imaging to determine disease progression in ADPKD defined as a change in both renal and renal cyst volumes and renal function over time. Subjects enrolled in the initial CRISP study are invited to continue participation in the succeeding CRISP studies.

This study requires four annual visits to UAB. Some of the procedures are: physical exam by MD, MRI of kidneys, collect blood and urine sample. There is compensation for travel expenses and two annual visits.

Status of the trial: Enrolling by invitation only

Criteria: Male and female subjects, age ≥ 18 years with confirmed diagnosis of ADPKD (during participation in prior Tolvaptan trials) who have:
•             Completed and transferred from the double-blind Trial 156-13-210 (12-month period including post treatment follow-up, regardless of whether this was on-treatment or off-treatment), or
•             Completed Trial 156-08-271 or a prior tolvaptan trial, or
•             Interrupted or discontinued treatment in a prior tolvaptan ADPKD trial other than Trial 156-13-210. Subjects may be enrolled with the medical monitor approval, and additional close monitoring may be required at the beginning of the study.

Estimated glomerular filtration rate (eGFR) ≥ 20 mL/min/1.73m2 within 45 days of the baseline visit. Subjects who have an eGFR between 15 and 19 mL/min/1.73m2 may be enrolled with medical monitor approval
Brief Description: This trial is a phase 3b to evaluate and describe the long-term safety of Tolvaptan treatment in ADPKD patients with CKD (chronic kidney disease). Eligible Subjects will enter the trial from Trial 156-08-271 or other Tolvaptan interventional trials. Renal function will be assessed during screening by using historical laboratory values for serum creatinine levels to calculate the estimated glomerular filtration rate (eGFR). General safety endpoints will be assessed and also relevant safety endpoints for the trial as serum transaminase elevations in frequency & serum sodium excursions.

This study requires several visit to UAB. Some of the procedures are: physical exam by MD, collect blood and urine sample.  Tolvaptan will be provided at no cost for the subject participating in the study. Compensation is $75.00 per visit.

Title of Trial:  “Multicenter, Double-Blinded, Placebo-Controlled Study of PRT-201 Administered Immediately after Radiocephalic Arteriovenous Fistula Creation in Patients with Chronic Kidney Disease”

Status of the trial:  Enrollment Complete

Brief Description:  This research study is designed to assess the safety and effectiveness of an experimental drug called PRT-201 in patients who have chronic kidney disease and who are undergoing surgery to create a new access point to their bloodstream for hemodialysis. PRT-201 is a protein that has been shown in previous research studies to help keep vessels patent when applied to the outside surface of the blood vessels (arteries and veins) in patients who undergo surgery to create an arteriovenous fistula (AVF).

The purpose of this study is to determine whether PRT-201 when applied to a limited segment of your blood vessel (about 2 inches) immediately after surgery is safe and improves the patency of your AVF.

Status of the trial: Enrolling

Brief Description: This research study is designed to assess the safety and effectiveness of an experimental drug called vonapanitase in patients whoe have chronic kidney disease and who are undergoing surgery to create a new access to their bloodstream for hemodialysis. An experimental drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). 206 patients with chronic kidney disease have been administered vonapanitase in previous studies sponsored by Proteon Therapeutics. In those studies, vonapanitase is called PRT-201. In previous research studies vonpanitase has been shown to help keep vessels open when applied to the outside surface of the blood vessels (arteries and veins) in patients that undergo surgery to create an AVF. Purpose of the study is to determine whether vonapanitase is well tolerated and can keep the blood vessel open (improve patency) of your AVF when applied to a limited segment of your blood vessel (about 2 inches) immediately after surgery.

This study requires 8 visits to UAB. Some of the procedures are to collect: physical exam by MD, Ultrasound and blood samples. Compensation is $50.00 per visit.
