Clinical Trials


  • A Phase III Study to Investigate the Efficacy and Safety of Baxdrostat in Combination With Dapagliflozin on CKD Progression in Participants With CKD and High Blood Pressure. Not Recruiting

    The purpose of this study is to measure the efficacy and safety of baxdrostat/dapagliflozin in participants ≥ 18 years of age with CKD and HTN. This study consists of a screening, a 4-week dapagliflozin run-in period for participants naïve to SGLT2i at baseline; a 24-month double-blind period in which participants will receive either baxdrostat/dapagliflozin or dapagliflozin; and a 6-week open-label period in which all participants will discontinue baxdrostat/placebo and receive dapagliflozin alone. Site visits will take place at 2-, 4-, 8-, and 16- weeks following randomisation. Thereafter visits will occur approximately every 4 months, until the 24-month visit at which time baxdrostat/placebo will be discontinued. Participants will continue open-label dapagliflozin for another 6-weeks (approximately), where reassessment of GFR will occur for the primary efficacy endpoint. In the event of premature discontinuation of blinded study intervention, participants will continue in the study and receive open-label dapagliflozin monotherapy, unless the participant meets dapagliflozin specific discontinuation criteria, in which case all study interventions will be discontinued.

    Stanford is currently not accepting patients for this trial. For more information, please contact AstraZeneca Clinical Study Information Center, 1-877-240-9479.

  • The Role of Mineralocorticoid Receptors in the Treatment of Primary Hypertension. Current hypertension reports Bahrainwala, J. Z., Bhalla, V. 2026; 28 (1): 7

    Abstract

    Hypertension affects over one billion individuals worldwide and remains the leading modifiable risk factor for cardiovascular disease. While first-line therapies including thiazide-type diuretics, angiotensin converting enzyme inhibitors / angiotensin receptor blockers, and calcium channel blockers can effectively control blood pressure in many patients, 10-20% develop resistant hypertension requiring additional therapeutic approaches. Steroidal mineralocorticoid receptor antagonists (MRAs) have emerged as essential fourth-line agents for resistant hypertension, with spironolactone demonstrating superior efficacy compared to other add-on therapies in the landmark PATHWAY-2 trial. The pathophysiological rationale for MRAs includes natriuretic effects, vasodilatory properties and target organ protection through anti-fibrotic mechanisms. Novel non-steroidal MRAs offer improved selectivity and reduced endocrine side effects compared to traditional agents, potentially expanding the therapeutic window for mineralocorticoid receptor blockade. In this review, we discuss the established role of MRAs in primary and resistant hypertension management and discuss consideration of MRAs in certain hypertension patient populations. We also briefly review patient selection strategies and future directions for this important therapeutic class.

  • Kidney Denervation: Latest Breakthroughs and Insights. Clinical journal of the American Society of Nephrology : CJASN Bahrainwala, J. Z., Etemadi, A., Chang, T. I. 2025

    Abstract

    Kidney denervation has emerged as an interventional treatment for the ever-increasing prevalence of uncontrolled hypertension that recently garnered Unites States Food and Drug Administration approval. Kidney denervation is a minimally invasive catheter-based procedure that ablates the sympathetic nerves around the kidney arteries using a variety of modalities. Clinical trial data have generally demonstrated that kidney denervation is a safe procedure, but efficacy data are mixed. In addition, important populations were excluded from these trials, including patients with advanced chronic kidney disease and kidney transplants. Currently, it is still unclear which patients with hypertension will have an appropriate therapeutic effect after undergoing kidney denervation, and there is no available biomarker to assist in predicting a patient's blood pressure response after kidney denervation. When considering when to offer kidney denervation, patients should ideally be evaluated by a multidisciplinary team with the proper expertise to evaluate the appropriateness of the referral and discuss the risks and benefits to allow for shared decision-making. Ongoing and future studies will help to address current unanswered questions that remain about longer-term safety and efficacy of renal denervation, particularly in populations poorly represented by current trials. Kidney denervation can be an important therapy that can be used to complement antihypertensive medications and lifestyle changes to improve hypertension control.

    Abstract

    Diagnostic errors are commonly driven by failures in clinical reasoning. Deficits in clinical reasoning are common among graduate medical learners, including nephrology fellows. We created and validated an instrument to assess clinical reasoning in a national cohort of nephrology fellows and established performance thresholds for remedial coaching.Experts in nephrology education and clinical reasoning remediation designed an instrument to measure clinical reasoning through a written patient-encounter note from a web-based, simulated acute kidney injury (AKI) consult. The instrument measured clinical reasoning in three domains (Problem Representation, Differential Diagnosis with Justification, Diagnostic Plan with Justification). Inter-rater reliability was established in a pilot cohort (n = 7 raters) of first-year nephrology fellows using a two-way random effects agreement intraclass correlation coefficient model. The instrument was then administered to a larger cohort of first-year fellows to establish performance standards for coaching using the Hofstee method (n = 6 raters).In the pilot cohort, there were 15 fellows from 4 training program, and in the study cohort, 61 fellows from 20 training programs. The intraclass correlation coefficients for Problem Representation, Differential Diagnosis, and Diagnostic Plan were 0.90, 0.70, and 0.50. Passing thresholds (% total points) in Problem Representation, Differential Diagnosis, and Diagnostic Plan were 59%, 57%, and 62%. Fifty-nine percent (n=36) met the threshold for remedial coaching in at least one domain.We provide validity evidence for a simulated AKI consult for formative assessment of clinical reasoning in nephrology fellows. The majority of fellows met criteria for coaching in at least one of three reasoning domains, demonstrating a need for learner assessment and instruction in clinical reasoning.

  • Use of Dietary Supplements in Living Kidney Donors: A Critical Review AMERICAN JOURNAL OF KIDNEY DISEASES Leonberg-Yoo, A. K., Johnson, D., Persun, N., Bahrainwala, J., Reese, P. P., Naji, A., Trofe-Clark, J. 2020; 76 (6): 851-860

    Abstract

    Dietary supplement use is high among US adults, with the intention by users to promote overall health and wellness. Kidney donors, who are selected based on their overall good health and wellness, can have high utilization rates of dietary supplements. We provide a framework for the evaluation of living kidney donors and use of dietary supplements. In this review, dietary supplements will include any orally administered dietary or complementary nutritional products, but excluding micronutrients (vitamins and minerals), food, and cannabis. Use of dietary supplements can influence metabolic parameters that mask future risk for chronic illness such as diabetes and hypertension. Dietary supplements can also alter bleeding risk, anesthesia and analgesic efficacy, and safety in a perioperative period. Finally, postdonation monitoring of kidney function and risk for supplement-related nephrotoxicity should be part of a kidney donor educational process. For practitioners evaluating a potential kidney donor, we provide a list of the most commonly used herbal supplements and the effects on evaluation in a predonation, perioperative donation, and postoperative donation phase. Finally, we provide recommendations for best practices for integration into a comprehensive care plan for kidney donors during all stages of evaluation. We recommend avoidance of dietary supplements in a kidney donor population, although there is a paucity of data that identifies true harm. Rather, associations, known mechanisms of action, and common sense suggest that we avoid use in this population.

  • Preoperative Risk Assessment and Management in Adults Receiving Maintenance Dialysis and Those With Earlier Stages of CKD AMERICAN JOURNAL OF KIDNEY DISEASES Bahrainwala, J. Z., Gelfand, S. L., Shah, A., Abramovitz, B., Hoffman, B., Leonberg-Yoo, A. K. 2020; 75 (2): 245-255

    Abstract

    With an increasingly aging population and improved mortality in individuals with end-stage kidney disease, more surgeries are being performed on patients with all stages of chronic kidney disease (CKD). This high-risk population carries unique risk factors that have been associated with increased adverse perioperative outcomes, including acute kidney injury, cardiovascular events, and mortality. In this article, we review the literature describing absolute risks associated with common surgeries performed in patients with CKD and patients receiving maintenance dialysis. We also review perioperative optimization with special risk assessment including evaluation of cardiovascular and bleeding risk evaluation, hypertension management, and timing of dialysis. Predictive model scores are reviewed as a method to stratify risk for acute kidney injury, major adverse cardiac events, or other serious complications with elective surgeries. A multidisciplinary approach with individualized counseling is necessary to counsel the patient with advanced CKD or patients treated with maintenance dialysis considering elective surgery.

  • Use of Radiocontrast Agents in CKD and ESRD SEMINARS IN DIALYSIS Bahrainwala, J. Z., Leonberg-Yoo, A. K., Rudnick, M. R. 2017; 30 (4): 290-304

    Abstract

    Contrast exposure in a population with chronic kidney disease (CKD) requires additional consideration given the risk of contrast-induced nephropathy (CIN) after exposure to iodinated contrast as well as systemic injury with exposure to gadolinium-based contrast agents (GBCA). Strategies to avoid CIN, and manage patients after exposure, including extracorporeal removal of contrast media, may differ among an advanced CKD population as compared to a general population. There is strong evidence to support the use of isotonic volume expansion and the lowest dose of low-osmolar or iso-osmolar contrast media possible to decrease CIN. The current literature on other newer prophylactic strategies such as statins, remote ischemic preconditioning, discontinuation of renin angiotensin aldosterone system (RAAS) blockade, and RenalGuard is limited thus these strategies cannot currently be recommended as routine prophylaxis for CIN. The use of extracorporeal removal of contrast agents as prophylaxis to reduce CIN has been the subject of multiple studies; however, data do not support a beneficial effect in reduction in CIN. Immediate removal of contrast by dialysis in a maintenance dialysis population is also not recommended, unless an individual's cardiopulmonary status is dependent on strict volume management. In patients with reduced renal function, GCBA exposure increases the risk of NSF. In patients with AKI, CKD stage 3 or greater (eGFR <30 ml/minute/1.73 m2 ), or patients on dialysis, we do not recommend the use of GBCA and alternative imaging modalities should be considered. If patients absolutely need magnetic resonance imaging with GBCA, we recommend the use of the lowest dose possible of the newer macrocylic, ionic agents (gadoterate meglumine) as well as immediate postprocedural HD in patients already on HD or peritoneal dialysis or with stage 5 CKD and with a functioning dialysis access already in place.

  • Diagnosis of Iron-Deficiency Anemia in Chronic Kidney Disease SEMINARS IN NEPHROLOGY Bahrainwala, J., Berns, J. S. 2016; 36 (2): 94-98

    Abstract

    Anemia is a common and clinically important consequence of chronic kidney disease (CKD). It is most commonly a result of decreased erythropoietin production by the kidneys and/or iron deficiency. Deciding on the appropriate treatment for anemia associated with CKD with iron replacement and erythropoietic-stimulating agents requires an ability to accurately diagnose iron-deficiency anemia. However, the diagnosis of iron-deficiency anemia in CKD patients is complicated by the relatively poor predictive ability of easily obtained routine serum iron indices (eg, ferritin and transferrin saturation) and more invasive gold standard measures of iron deficiency (eg, bone marrow iron stores) or erythropoietic response to supplemental iron. In this review, we discuss the diagnostic utility of currently used serum iron indices and emerging alternative markers of iron stores.
