Clinical Trial Research

Our division participates in various clinical trials to improve the care of kidney disease, including glomerular disease, transplantation, chronic kidney disease, hypertension, and dialytic therapies. Please review the information below about the specific trials. Of note, active patient enrollment in some of the trials has ended. 

Diabetic Kidney Disease - Enrolling OHSU Patients

TRIDENT (Transformative Research in Diabetic Nephropathy)

Aim: To understand the clinical and molecular basis of progressive diabetic kidney disease.

Patient Population: Adults with Type 1 or Type 2 diabetes who need a kidney biopsy.

Contact: Please review with your kidney doctor. More information is available on the study website, the NIH Registry of Trials website, and the trial publications (Cellular Diversity of the Kidney, Role of Glomerular Epithelial Injury in Kidney Function Decline).

Autoimmune Kidney Disease - Enrolling OHSU Patients

Kidney Disease Biorepository

Aim: This is a patient database that stores clinical information, kidney biopsy specimens, and blood/urine samples from patients with, or at risk for, autoimmune kidney disease. This data will be used in future research focused on understanding the diagnosis, prognosis, and treatment of autoimmune kidney conditions. 

Patient Population: Adults age 18-89 who have autoimmune kidney disease, or are at risk for autoimmune kidney disease, based on their other medical conditions or medications. 

Contact: Email Madison Stanaway if you are interested in donating blood and urine to this research repository.

Diabetic Kidney Disease - Enrolling VA Patients

PTXRX (Pentoxifylline in Diabetic Kidney Disease)

Aim: To evaluate the effectiveness of pentoxifylline in diabetic kidney disease.

Patient Population: Adults with type 2 diabetes and stage 3 or 4 chronic kidney disease. Patients with type 1 diabetes, non-diabetic kidney disease, or severe chronic health conditions are excluded. 

Contact: This is a VA trial only. Please review with your kidney doctor. More information is available on the NIH Registry of Trials website.

Hypertension - Completed Enrollment

SPYRAL (Global Clinical Study of Renal Denervation With the Symplicity Spyral™ Multi-electrode Renal Denervation System in Patients With Uncontrolled Hypertension on Standard Medical Therapy)

Aim: This is a multinational randomized placebo-controlled trial investigating the effectiveness of a procedural intervention (renal denervation) to lower blood pressure. This procedure is designed to block the connection between the nervous system and the kidney in order to reduce blood pressure. More information is available at the NIH Registry of Trials website and in the trial's initial publication.  

Dialysis and Bloodstream Infections - Completed Enrollment

GARNET™ Filter Feasibility of Hemodialysis With the GARNET Device in Chronic Hemodialysis Patients With a Bloodstream Infection 

Aim: This is an initial study to evaluate the feasibility of hemodialysis using the GARNET device. This is designed to perform traditional hemodialysis in addition to binding pathogens and pathogen-associated molecular patterns to clear them from the bloodstream, potentially improving infection treatment. More information is available on the NIH Registry of Trials website.

IgA Glomerular Disease - Completed Enrollment

NefIgArd (Nefecon in Patients With Primary IgA Nephropathy at Risk of Progressing to End-stage Renal Disease)

Aim: To evaluate the efficacy of a minimally absorbed oral steroid, budesonide (Nefecon), for the treatment of IgA Nephropathy. More information is available on the NIH Registry of Trials website and in the trial's initial and 2-year results publications. 

Chronic Kidney Disease - Completed Enrollment

EAGLE (An Extended Access Program for Bardoxolone Methyl in Patients with CKD)

Aim: To assess the long-term safety of bardoxolone methyl in patients who previously participated in a clinical study of bardoxolone methyl. More information is available at the NIH Registry of Trials website

Finding Clinical Trials

Some patients may wish to explore clinical trials outside of OHSU. The websites below may help patients find a relevant trial. Please review your care and potential interest in any study with your kidney doctor. Of note, these websites are not curated by OHSU Nephrology and information may at times be outdated or incorrect.
