A PHASE 3 SINGLE CENTER STUDY OF ISLET TRANSPLANTATION IN NON-UREMIC DIABETIC PATIENTS
Type 1 diabetes is an autoimmune disease in which the insulin-producing pancreatic beta cells are destroyed, resulting in poor blood sugar control. The purpose of this study is to determine the safety and effectiveness of islet transplantation, combined with immunosuppressive medications, specifically using Campath as induction, for treating type 1 diabetes in individuals experiencing hypoglycemia unawareness and severe hypoglycemic episodes.
Chronic Kidney Disease Research Biorepository
The objective of this study is to create a biorepository of stored blood and urine specimens and demographic and clinical data collected from patients with chronic kidney disease and healthy volunteers for use in chronic kidney disease research
Transformative Research In Diabetic Nephropathy (TRIDENT) (SP0043185)
This is a prospective, observational, cohort study of patients with a clinical diagnosis of diabetes who are undergoing clinically indicated kidney biopsy. The intent is to collect, process, and study kidney tissue and to harvest blood, urine and genetic materials to elucidate molecular pathways and link them to biomarkers that …
This is a prospective, observational, cohort study of patients with a clinical diagnosis of diabetes who are undergoing clinically indicated kidney biopsy. The intent is to collect, process, and study kidney tissue and to harvest blood, urine and genetic materials to elucidate molecular pathways and link them to biomarkers that characterize those patients have a rapid decline in kidney function (> 5 mL/min/1.73m2/year) from those with lesser degrees of kidney function change over the period of observation. High through-put genomic analysis associated with genetic and biomarker testing will serve to identify key potential therapeutic targets for DKD by comparing patients with rapid and slow progression patterns. Each participating clinical site will search for, consent, harvest the biopsy sample, and enroll the participants as required for the TRIDENT protocol.

Evaluation of Renal Microvascular Perfusion by Contrast Enhanced Ultrasound
Contrast Enhanced Ultrasound Study:The study’s purpose is to measure blood flow to and from the kidney via contrast-enhanced ultrasound (contrast agent, Lumason®, is given via IV administration)Participation consists of 5 study visits that are spread out over the course of 24 months (Healthy and ESRD participants …
Contrast Enhanced Ultrasound Study:
A Randomized, Multicenter, Double-Blind, Parallel, Active-Control Study of the Effects of Sparsentan, A Dual Endothelin Receptor and Angiotensin Receptor Blocker, on Renal Outcomes in Patients with Primary Focal Segmental Glomerulosclerosis
(ACTIVE, NOT RECRUITING) This is a randomized, multicenter, double-blind, parallel, active-control study. The investigational drug (sparsentan) is a dual acting angiotensin receptor blocker and endothelin receptor agonist. The active control is irbesartan. Patients who meet eligibility criteria will require wash out from renin-angiotensin-aldosterone system (RAAS) blockers, if applicable prior to their first dose of study drug. Patients will be randomly assigned in a 1:1 ratio to receive either sparsentan or active control (irbesartan).
1. Primary FSGS
2. Male or Female aged 18-75 years
3. Urine protein/creatinine ratio ≥ 1.5 g/g
4. Estimated glomerular filtration rate (eGFR) ≥ 30
5. Blood pressure criteria: ≥100/60 mmHg and ≤160/100 mmHg
6. Women of child bearing potential must agree to the simulataneous use of 2 medically accepted methods of contraception from randomization until 90 days after the last dose of study medication. Males, unless surgically sterile, must agree to use highly reliable methods of contraception from randomization until 90 days after the last dose of study medication.
1. Secondary FSGS
2. History of type 1 diabetes, uncontrolled type 2 diabetes, organ transplantation, heart failure (Class II-IV), malignancy, significant valvular disease, or alcohol/substance abuse.
3. History of significant cerebrovascular disease and/or coronary artery disease within 6 months
4. Body Mass Index (BMI) > 40
3. Females who are pregnant, plan to become pregnant through the course of the study, or are breastfeeding. Males who plan to father a child during the course of the study.
The “RADIANCE II” Pivotal Study A Study of the ReCor Medical Paradise System in Stage II Hypertension
This study is enrolling patients who have high blood pressure ("hypertension") and are taking two medications or fewer for it. It is believed that in some patients with high blood pressure, the nerves surrounding the blood vessels leading to the kidneys (renal arteries) are too active and that this may …
This study is enrolling patients who have high blood pressure ("hypertension") and are taking two medications or fewer for it. It is believed that in some patients with high blood pressure, the nerves surrounding the blood vessels leading to the kidneys (renal arteries) are too active and that this may be causing high blood pressure. Renal denervation is a procedure where a catheter is placed inside these blood vessels and creates heat to disable the nerves and potentially lower blood pressure. The purpose of this clinical study is to see whether a medical device called the Paradise Renal Denervation System (also called The Paradise System) can lower high blood pressure in patients who are known to have hypertension.
Immune checkpoint inhibitor-associated acute kidney injury
Since 2011, six immune checkpoint inhibitors (ICIs), a type of immunotherapy, have been approved by the Federal Drug Administration for use in patients with cancer.

Since 2011, six immune checkpoint inhibitors (ICIs), a type of immunotherapy, have been approved by the Federal Drug Administration for use in patients with cancer. These medications have been demonstrated to have great promise for treating a variety of cancers. However, there are toxicities associated with these agents, known as immune-related adverse events (AKI), some of which can be fatal. Affected organs include the skin (rash), gastrointestinal tract(diarrhea), and the kidneys (acute kidney injury [AKI]). This study, led by Drs. Shruti Gupta and David Leaf at Brigham and Women’s Hospital, has the goal of collecting data on over 300 ICI-associated acute kidney injury cases from more than 30 academic medical centers worldwide. We will characterize the clinical features of ICI-associated AKI in the hope that this will help us to determine predictors of toxicity and best practices for management.
