A Clinical Trial of MK-2828 in People With Kidney Disease (MK-2828-006)

The goal of this trial is to measure what happens to 1 or 2 doses of MK-2828 in a person's body over time (pharmacokinetic or PK trial). Researchers want to learn if the PK of people with certain types of kidney disease is similar to the PK of healthy people.

Groundbreaking Renal Assist Device Intervening to ENhance cardioThoracic Surgery Outcomes

Patients with renal insufficiency who undergo cardiac surgery with cardiopulmonary bypass (CPB) are at significant risk for exacerbation of renal dysfunction postoperatively. This in turn is associated with an increased risk of prolonged intensive care unit (ICU) length of stay, other comorbidities including surgical complications and 30-day mortality. Renal impairment is generally identified based on an increase in serum creatinine concentration and/or a certain magnitude decrease in estimated glomerular filtration rate (eGFR). The JuxtaFlow® Renal Assist Device (RAD) is designed to sustain or enhance glomerular filtration perioperatively for patients with renal insufficiency by applying a mild controlled negative pressure to the collecting system via the renal pelvis, thereby increasing effective filtration pressure and reducing tubular pressure. This mechanism is designed to support the kidneys' functions during times of renal stress that would be associated with intrarenal edema, volume overload, increased venous pressure, and inflammatory response. By supporting renal function, specifically during the acute stress of CPB, JuxtaFlow holds promise to protect nephron function, decrease renal hypoxia, and provide multifactorial kidney function support to maintain their ability to manage future stress.

A Study to Learn How the Body Processes the Study Medicine PF-07328948 in People With Reduced Kidney Function

The purpose of this study is to learn how the study medicine PF-07328948 is processed by the body and how safe and tolerable it is in adults with different levels of kidney function. The study will include participants who: * Are aged 18 to 80 years. * Either have normal kidney function or long-term reduced kidney function (moderate or severe). * Have a BMI (body mass index) of 17.5 to 40 kilogram per meter squared, inclusive, and a total body weight of more than or equal to 45 kilograms or 99 pounds. All participants will receive a single dose of PF-07328948 as a tablet taken by mouth. Participants will stay at a clinical research unit for about 6 days to receive the study medicine and undergo safety checks. Total participation lasts up to 64 days, including screening, inpatient stay, and a follow-up call. The study is not randomized or blinded, meaning all participants and study staff know which treatment is being given. Group assignment is based on kidney function tests done during screening. The results will help researchers understand how reduced kidney function affects the way PF-07328948 works in the body.

Mannitol Versus Nitroglycerin for Kidney Injury Prevention in Robotic-assisted Radical Prostatectomy or Cystectomy

Laparoscopic and minimally-invasive robotic access has transformed the delivery of urological surgery. While associated with numerous desirable outcomes including shorter post-operative stay and faster return to preoperative function, these techniques have also been associated with morbidity such as reduced renal blood flow and post-operative renal dysfunction. The mechanisms leading to these renal effects complex are multifactorial, and have not been fully elucidated. However they are likely to include direct effects from raised intra-abdominal pressure, and indirect effects secondary to carbon dioxide absorption, neuroendocrine factors and tissue damage from oxidative stress. It is well documented that pneumoperitoneum places profound stress on the cardiovascular, respiratory and gastrointestinal systems; it also places strain on the renal system. During robotic surgery, continuous pneumoperitoneum and continuous rising of intra-abdominal pressure causes transient oliguria. Moreover, kidney function, estimated by the GFR, deteriorates during elevated intra abdominal pressure (IAP), and most of the studies identified decrease in renal blood flow (RBF) and renal cortical perfusion. Studies conducted to assess the contribution of the nitric oxide (NO) system to the renal hemodynamic/function alterations during pneumoperitoneum, concluded that these adverse effects are probably related to interference with the NO system, and could be partially ameliorated by pretreatment with nitroglycerine. Mannitol is an osmotic diuretic and a renal vasodilator that promotes tubular flow, prevents intratubular cast formation, decreases postischemic cellular swelling, and might serve as a free radical scavenger. Mannitol has traditionally been administered before renal surgeries to minimize perioperative renal dysfunction according to preclinical animal studies and clinical experience with renal transplantation. However, high-level clinical data in support of this belief are not available. The aim of this study is to characterize the effects of increased intra-abdominal pressure on renal perfusion and function in cases undergoing robotic lower tract urologic surgeries, and to assess the contribution of either mannitol or nitroglycerin infusion to the renal hemodynamic/function alterations during pneumoperitoneum.

DESIR. Evaluation of the Pre-therapeutic Activity of Dihydropyrimidine dEShydrogenase (DPD) in Patients With Cancer and/or Renal Failure

Fluoropyrimidine drugs (5-Fluorouracil or 5-FU and its prodrug capecitabine) are a widely used in the treatment of numerous solid tumors in adults. Approximately 85% of administered 5-FU is rapidly catabolized in the liver into inactive dihydrofluorouracil (5-FUH2) by dihydro-pyrimidine dehydrogenase (DPD), leaving only a small fraction of the initial drug for an eventual transformation into cytotoxic metabolites. Impeded DPD activity is associated to an increase of cytotoxic metabolites leading to potentially very severe toxicities. To prevent these toxicities, a pre-therapeutic measurement of plasma uracil can help assess DPD activity. Indeed, uracil is an endogenous substrate of DPD and an increase in its plasma concentration may be associated with a decrease in DPD activity. In this case, a reduction of the fluoropyrimidine dose is suggested. However, the investigators observed that uracilemia increased concomitantly to the severity of renal impairment. There are two possible explanations for this observation. Either the renal impairment reduces the renal elimination of uracil from blood, or DPD activity is actually impaired. In both cases, this can explain an increase in plasma uracil concentration. However, the impact on fluoropyrimidine dosage is different in the two cases. If the increase in uracilemia is due to renal impairment, DPD activity remains unaffected and there is no need to reduce the fluoropyrimidine dose. If DPD activity is actually impaired, a reduction in the fluoropyrimidine dose is required. In cases of renal impairment, uracilemia may therefore not be as relevant for DPD assessment as in the absence of renal impairment. To assess if DPD activity is actually impede during renal impairment, the DPD activity of Peripheral Blood Mononuclear Cells (PBMCs) will be assessed together with uracilemia in patients with or without renal impairment. As uracilemia decreases after dialysis, the DPD activity of Peripheral Blood Mononuclear Cells (PBMCs) will also be assessed in patient before and after dialysis. Four groups of 50 patients will be studied: patients with normal renal function with hyperuracilemia (uracilemia ≥ 16 ng/mL) or normal uracilemia (uracilemia \< 16 ng/mL) ; and patients with renal impairment with hyperuracilemia (uracilemia ≥ 16 ng/mL) or normal uracilemia (uracilemia \< 16 ng/mL). The main objective of the study is to describe the distribution of DPD activity in these four populations. The secondary objectives are to determine in normorenal patients the optimal threshold for DPD activity in non-deficient patients, allowing differentiation between deficient and non-deficient patients based on uracilemia ; and to describe in patients with impaired renal function the distribution of uracilemia with respect to the threshold previously described with the aim of verifying the relevance of uracilemia as a marker of DPD activity in such patients.

Development of a Biomarker Panel for the Earlier Prediction of Acute Kidney Injury in Patients With Diabetes

Patients living with diabetes mellitus have double the risk of kidney failure compared to patients without diabetes following use of dye in many x-rays and procedures to diagnose and treat narrowing of the arteries (blood vessels) in the heart that can lead to angina or a heart attack. Heart disease is the commonest cause of death in patients with diabetes. People with diabetes are more likely to need these tests/treatments. By identifying those at greater risk of kidney complications we may be able to make these tests/treatments safer and offer them to more patients with diabetes.
