NCT05702944
Pheochromocytoma and paraganglioma (PPGL) are rare neuroendocrine tumors originating from catecholamine producing chromaffin cells in the adrenal medulla and extra-adrenal paraganglia. The overall age-standardized incidence rate is 0.18 per 100,000 person-years in Korea. The definitive treatment of PPGL is surgical excision of tumor. However, surgery is associated with a high risk of perioperative hemodynamic instability (HI). To avoid perioperative HI in patients diagnosed with PPGL, preoperative management including routine use of alpha blockade and volume expansion has been advocated by several guidelines. While unstable hypertension and tachycardia should be controlled in patients with PPGL, there is controversial that all patients diagnosed with PPGL should undergo preoperative pharmacological treatment, especially alpha blockade. The most important risk of preoperative alpha blockade use is perioperative hypotension. A recent study reported that patients diagnosed with PPGL postoperatively may have no further higher risk of intraoperative hypertension than those diagnosed preoperatively despite insufficient preoperatively management of PPGL. Therefore, it is a very important to study the relationship between HI and preoperative alpha blockade in normotensive patients diagnosed with PPGL. The aim this study is to analyze the effect and safety of omitting preoperative alpha-adrenergic blockade for normotensive pheochromocytoma through a prospective randomized controlled trial. The patients is divided into two groups. The patients in control group take a phenoxybenzamine at least 2 to 5 weeks before surgery. The patients in case group do not take a phenoxybenzamine. Primary outcome is to evaluate the percentage of time during surgery with systolic blood pressure more than 160mmHg or average blood pressure less than 60mmHg. And secondary outcomes are to evaluate hemodynamic instability in preoperative ward and postoperative ward.
NCT06447103
This phase II trial compares the safety and effectiveness of 89Zr-DFO-GmAb positron emission tomography (PET)/computed tomography (CT) compared to contrast-enhanced CT after surgery in detecting clear cell renal cell cancer that has come back (recurrent). For some patients, the risk of recurrence after surgery remains high. Conventional CT methods, such as contrast-enhanced CT, may not detect small volume or micrometastatic disease. PET/CT with radiotracers, such as 89Zr-DFO-GmAb, may improve detection of tumor cells. Girentuximab (GmAb), a monoclonal antibody, is tagged with zirconium-89, a radioactive atom (which is also known as an isotope). The zirconium-89 (89Zr) isotope is attached to girentuximab with desferrioxamine (DFO) and this combined product is called 89Zr-DFO-girentuximab. 89Zr-DFO-girentuximab attaches itself to a protein on the surface of clear cell renal cell tumor cells called CAIX. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, 89Zr-DFO-GmAb. Because some cancers, including clear cell renal cell cancer, take up 89Zr-DFO-GmAb it can be seen with PET. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. Using contrast agents with CT scan to enhance the images (contrast-enhanced CT) is standard of care imaging. 89Zr-DFO-GmAb PET/CT may be safe and effective compared to contrast-enhanced CT in detecting recurrent clear cell renal cell cancer after surgery.
NCT07017270
This study aims to determine if GLP1RA is safe and tolerable in maintenance dialysis population, adherence, and feasibility of a larger definitive cardiovascular outcome trial in this population. Participants will be randomized 1:1 to either weekly subcutaneous semaglutide versus usual care and followed for 26 weeks.
NCT07018037
The aim of this project is to descriptively explore the trend of torquetenovirus viral load TTV during therapy with immune checkpoint inhibitor ICI in these patients, to evaluate a possible role of this virus as a biomarker of response.
NCT06694558
This is a cross-sectional study in patients with Type 1 diabetes (TID) and chronic kidney disease (CKD) to test if time in range (TIR) affects the degree of hyperglycemia required for monocyte activation, podocyte injury, and assess if monocyte activation is attenuated by glucagon-like peptide (GLP-1) agonist treatment ex vivo.
NCT03471117
Chronic kidney disease (CKD) is associated with a higher risk of cardiovascular disease and death. An overactive sympathetic nervous system in CKD patients is one of the major mechanisms increasing the cardiovascular risks in this patient population. Recently, some studies have shown that a drug typically used to improve glucose control (pioglitazone) may also reduce sympathetic nerve activity and improve blood vessel function. The goal of this study is to determine whether a short-term treatment with pioglitazone can reduce sympathetic nerve impulses throughout the body in CKD patients.
NCT07012941
The holmium laser is currently considered the gold standard for lithotripsy on urinary lithiasis, whereas the super-pulsed thulium fibre laser is a relatively new technology. Through a multi-center prospective randomised clinical study that mainly aims to explore the effectiveness and safety of a super-pulsed fibre thulium laser compared to a holmium laser in the treatment of upper ureteral and renal stones (10mm\<cumulative maximum diameter ≤ 25mm) in retrograde intrarenal surgery. The research participants are assigned randomly to undergo retrograde intrarenal surgery (RIRS) either using a super-pulsed thulium fibre laser or a holmium-YAG laser with an allocation ratio of 1:1. The secondary aim of this study is to provide high-level evidence for the development of diagnostic and treatment guidelines in the field of urolithiasis, both domestically and internationally. The outcomes of the RIRS procedures are compared for the two treatment arms.

The hypothesis is that 3 months' treatment with SZC versus placebo will enable RASi (Irbesartan) maximisation in a cohort of patients with diabetic kidney disease.
NCT06742762
This is a Phase I, multicentre, single-dose, non-randomised, open-label, parallel-group study to examine the PK, safety, and tolerability of AZD5004 in male and female participants with severe renal impairment and moderate renal impairment (optional) compared with male and female participants with normal renal function.
NCT03297593
Immunotherapy with checkpoint inhibitors that target PD-1 and CTLA-4 have shown activity in mRCC. However, the optimal schedule of the combination therapy has yet to be defined. The objective of the trial is to determine the efficacy of combination immunotherapy of nivolumab and ipilimumab in patients with metastatic renal cell carcinoma. The expansion phase shall address the role of ipilimumab in case of clinically insignificant progression.
NCT06372431
This study is a multi-centre, non-interventional, observational, prospective study with retrospective analysis. The main purpose of the study is to describe the rate of CKD diagnosis in patients with AH and CKD markers. This study will include 10 000 adult outpatients with arterial hypertension, who have one or more Chronic Kidney Disease laboratory markers (without recorded CKD diagnosis prior to enrolment) and have no diabetes mellitus or symptomatic chronic heart failure, who are monitored and treated by cardiologists or internal medicine specialists in approximately 50 outpatient sites in about 20 regions in Russia. This observational study does not provide for any diagnostic and therapeutic procedures other than those used in routine practice.
NCT05078047
Immunotherapy (IO), such as treatment with anti-PD-1, PD-L1, or CTLA-4 inhibitors, is a rapidly expanding treatment for multiple metastatic cancers with improved survival for certain cancers. However, the optimal duration of immunotherapies is currently unknown. Our hypothesis is that a reduced dose intensity of IO could be as effective as the current standard treatment in term of prevention of the disease progression. If proved right, this study will have a positive medico-economic impact by reduction of the costs associated with the treatment and the toxicity, and an increase of the patients' quality of life.
NCT02419495
This phase Ib trial studies the side effects and best dose of selinexor when given together with several different standard chemotherapy or immunotherapy regimens in treating patients with malignancies that have spread to other places in the body and usually cannot be cured or controlled with treatment (advanced). Selinexor may stop the growth of cancer cells by blocking enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Studying selinexor with different standard chemotherapy or immunotherapy regimens may help doctors learn the side effects and best dose of selinexor that can be given with different types of treatments in one study.
NCT07004387
Orthotopic liver transplantation is the definitive treatment for end-stage liver failure, with renal failure being an important complication of this procedure that has implications for long- and short-term prognosis, affecting ICU stay and hospitalization time. Several studies have suggested that intravenous amino acids, particularly L-arginine, may have protective effects on renal function due to increased renal blood flow, which could be explained by enhanced production of nitric oxide among other mechanisms that are still unclear. In this context, we developed the hypothesis that the infusion of an amino acid solution in the perioperative period could reduce the incidence of acute renal failure in this group of patients; for this, we conducted a monocentric, analytical, prospective, interventional pilot study comparing standard treatment (in historically transplanted patients) with a group of patients who were administered amino acids in the perioperative period, considering that this medication is low-cost and has practically minimal side effects.
NCT06318676
The purpose of this study is to evaluate the drug levels of mezigdomide in participants with renal impairment.
NCT05149196
Radical nephrectomy and nephroureterectomy are common operations for the treatment of renal cell carcinoma and upper tract urothelial carcinoma, respectively. However, acute kidney injury frequently occurs after surgery. And the occurrence of acute kidney injury is associated with an increased risk of chronic kidney disease. Intraoperative hypotension is identified as an important risk factor of postoperative acute kidney injury. Preliminary studies showed that goal-directed hemodynamic management may reduce kidney injury after surgery but requires further demonstration. We hypothesized that goal-directed hemodynamic management combining hydration, inotropes, and forced diuresis to maintain pulse pressure variation \<9%, mean arterial pressure ≥85 mmHg, and urine flow rate \>200 ml/h (3 ml/kg/h) may reduce the incidence of acute kidney injury and improve long-term renal outcome after radical nephrectomy or nephroureterectomy. The purpose of this study is to investigate the effect of goal-directed hemodynamic management on the occurrence of acute and persistent kidney injury in patients following radical nephrectomy and nephroureterectomy.
NCT07001436
Azvudine(FNC)，a nucleoside reverse transcriptase inhibitor, make itself a better candidate to be co-formulated in other anti-HIV therapies, thus to improve patient's compliance. FNC is a broad-spectrum RNA virus inhibitor that inhibits the novel coronavirus RNA-dependent RNA polymerase. This trial uses a non-randomized, open-label, parallel, single-dose adaptive design aimed at investigating the effects of varying degrees of renal insufficiency on the pharmacokinetics, safety, and tolerability of a single oral dose of 3 mg Azvudine tablets in humans. On the first day of the study, a single oral dose of 3 mg ( 3 tablets ) of Azvudine tablets is taken orally on an empty stomach. Biological sample collection and safety examination will be performed in this trial.
NCT06831175
Adrenocortical carcinoma (ACC) is a rare aggressive malignant tumor. According to the literature, the 5-year survival rate of ACC is 12%-47%. For patients with advanced ACC, mitotane alone or combined with traditional chemotherapy was the first-line standard treatment, but its progression-free survival was only about 1 year. The efficacy of mitotane monotherapy is approximately 10% to 30%. FIRM-ACT trial reported an objective response rate (ORR) of 23.2% for etoposide, doxorubicin, cisplatin, and mitotane (EDP-M) chemotherapy regimen. Our phase II study found that PD-1 inhibitor camrelizumab and apatinib showed impressive clinical data in the second-line treatment of relapsed and metastatic ACC patients. The aim of this study is to evaluate the efficacy and safety of PD-1 inhibitor camrelizumab combined with apatinib and mitotane in advanced ACC, and to explore a new treatment strategy for patients with advanced ACC.
NCT06288451
The De-emphasize Parathyroid Hormone (DePTH) Study is a 12-month pragmatic, randomized, parallel-group, active comparator, open-label, blinded end-point study of 90 patients with incident or prevalent secondary hyperparathyroidism and kidney failure treated with in-center hemodialysis. It tests the hypothesis that low fixed-dose oral calcitriol (intervention) will have more favorable effects on a comprehensive panel of biomarkers that assesses mineral metabolism, bone turnover, and serum calcification propensity, compared with variably-dosed intravenous activated vitamin D titrated to PTH targets (usual care).
