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.

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.

A Clinical Study of Enlicitide in Participants With Severe Renal Impairment (MK-0616-032)

Researchers have designed a new study medicine called enlicitide decanoate as a new way to lower the amount of low-density lipoprotein cholesterol (LDL-C) in a person's blood. Enlicitide decanoate will be called "enlicitide" from this point forward, The purpose of this study is to learn what happens to enlicitide in a person's body over time (a pharmacokinetic (PK) study). Researchers will compare what happens to enlicitide in the body when it is given to people with severe renal impairment (meaning the kidneys do not work properly) and to people who are in good health. The researchers believe that the total amount of enlicitide in a person's body measured during the 24 hours after a dose will be similar in people with severe renal impairment and in healthy people.

Differentiating True Nephrotoxicity From Pseudo-nephrotoxicity: A Prospective Comparative Study of Vancomycin Plus Piperacillin-Tazobactam vs. Meropenem Using Serum Creatinine and Cystatin-C

This prospective comparative observational study will compare the incidence of true nephrotoxicity in adult patients receiving vancomycin in combination with either piperacillin-tazobactam or meropenem. Vancomycin plus piperacillin-tazobactam has been associated with a higher incidence of kidney injury based mainly on increases in serum creatinine. However, it remains uncertain whether these increases represent true kidney injury or pseudo-nephrotoxicity, in which serum creatinine increases without a corresponding decline in kidney function. To address this uncertainty, the study will prospectively assess kidney function using both serum creatinine and cystatin C. True nephrotoxicity will be identified when changes in both biomarkers meet the study criteria for acute kidney injury, while an increase in serum creatinine without a corresponding cystatin C increase will be considered pseudo-nephrotoxicity. The study will compare true nephrotoxicity between patients receiving vancomycin plus piperacillin-tazobactam and those receiving vancomycin plus meropenem. It will also evaluate the timing, persistence, severity, and recovery of kidney injury. The results may help clarify whether the higher rates of nephrotoxicity reported with vancomycin plus piperacillin-tazobactam represent true renal injury and may help guide antibiotic selection when balancing antimicrobial coverage and kidney safety.

Single-Dose Study to Evaluate the PKs of Pretomanid in Participants With Renal Impairment Compared to Participants With Normal Renal Function

This is a Phase 1, open-label, single-dose, sequential group study to compare the safety and pharmacokinetics (PK) of pretomanid in the following groups of participants: 1) participants with severe renal impairment including those with end stage renal disease (ESRD) not on dialysis, and participants with mild or moderate renal impairment, designated as Groups 2, 3, and 4, respectively; and 2) participants with normal renal function matched to the above renal impairment groups, designated as Groups 1A, 1B, and 1C, respectively. The study will be conducted following a reduced PK study design in Part A. Part A will enroll participants from Group 1A (i.e., 6 healthy matched controls) and Group 2 (i.e., 6 participants with severe renal impairment and ESRD, not on dialysis). A decision to proceed to Part B will be made after the PK of pretomanid, and safety in participants enrolled in Part A have been reviewed. If Part A demonstrates at least a 50% increase in pretomanid area under the plasma concentration-time curve (AUC) in Group 2 (severe renal impairments and ESRD, not on dialysis) relative to the exposures in Group 1A (matched participants with normal renal function), then the reduced PK study will extend to the full PK study to enroll participants into Part B (i.e., to investigate mild and moderate renal impairment). All Part B groups (1B, 1C, 3, and 4) will be enrolled concurrently. If the reduced PK study shows at least a 50% increase in AUC in patients with severe renal impairment and patients with ESRD not yet on dialysis relative to the matched healthy controls, a "full PK" renal impairment study in patients with all intermediate levels of renal function impairment should be conducted. Otherwise, no further study is recommended. The approximate patient involvement will be 3 months. The primary objective is to evaluate the PK profiles of pretomanid in plasma and urine after a single oral dose of 200 mg in participants with renal impairment compared to matched healthy controls.
