Active clinical trials for "Renal Insufficiency"

The purpose of this study is to confirm the safety and efficacy of Soluble Ferric Pyrophosphate (SFP) dialysate solution in maintaining iron delivery for erythropoiesis in anemic adult patients with chronic kidney disease (CKD) receiving hemodialysis. Efficacy will be measured primarily by the change from baseline in hemoglobin (Hgb).

The general aim of the trial is to assess the efficacy of one year treatment with long-acting somatostatin analogue (Octreotide LAR) compared with placebo in slowing kidney and liver growth rate in patients with ADPKD and moderate/severe renal insufficiency and to assess whether and to which extent this translates into slower renal function decline over 3-year follow-up.

The purpose of the study is to determine the long-term safety in treatment-emergent adverse events (TEAEs) of intravenous (IV) administration of Epoetin Hospira for maintenance of target hemoglobin (Hgb) levels in patients treated for anemia associated with chronic renal failure and on hemodialysis.

To determine the long term safety in treatment-emergent adverse events (TEAEs) of SC administration of Epoetin Hospira for maintenance of target hemoglobin (Hgb) levels in patients treated for anemia associated with chronic renal failure and on hemodialysis.

In accordance with the recently revised FDA draft renal impairment guidance (March 2010) which advises the conduct of renal impairment study in drugs that are not predominately eliminated through the renal route, the proposed study will be conducted to formally assess the pharmacokinetics (PK) of darapladib in severely renally impaired subjects. In this is an open-label, non-randomized study eight subjects with severe renal impairment will be recruited along with 8 healthy control subjects matched to the severe renal impairment subjects based on gender, body mass index (plus or minus 20%) and age (plus or minus 10 years). All subjects will receive repeat oral doses of darapladib 160 milligram (mg) for 10 consecutive days. The pharmacokinetics of darapladib and its metabolites; and safety and tolerability will be evaluated. All the subjects will be admitted to the clinic on the evening of Day -1. Subjects may check out of the clinic on Day 2 after all assessments are complete, but must return to the clinic each day (Days 3-8) for dosing and assessments. Subjects will be admitted to the clinic again on the evening of Day 9. After the last dose of the study drug, there will be a follow-up period which will include 2 visits (Day 20-24 and Day 38-52). The total study duration for each subject including the screening, treatment and follow-up periods will be approximately 11 weeks.

This study will assess the safety, tolerability, and pharmacokinetics (PK) study of a single dose of 150 mg AT1001 (migalastat HCl, GR181413A) administered orally to healthy subjects with normal renal function and to subjects with mild, moderate, and severe renal impairment.

The primary objective of this study is to evaluate the pharmacokinetic (PK) profile of oral bictegravir (formerly GS-9883) in adults with impaired renal function relative to matched, healthy controls with normal renal function. Each participant in the renal impairment groups will be matched for age (± 10 years), gender, and body mass index [BMI (± 20%, 18 ≤ BMI ≤ 40 kg/m^2)] with a participant in the control group.

This study is being done to investigate the impact of changing immunosuppressive medications from tacrolimus (Prograf®) to belatacept (Nulojix®) between three (3) and six (6) months after kidney transplantation. The immune system is the body's defense against infection and other disease. After transplantation, the body sees the new organ as "foreign" and tries to destroy or "reject" it. Immunosuppressive medications help to prevent the immune system from attacking the transplanted organ. The primary purpose of this research study is to evaluate the effects of three (3) different immunosuppressive treatments on rejection in post-transplant kidney recipients. This study will test whether switching from tacrolimus to belatacept will improve long-term kidney function. Three of the immunosuppressants used in this study- mycophenolic acid (MPA), mycophenolate mofetil (MMF) and tacrolimus- are medications approved by the United States Food and Drug Administration (FDA) to be used after transplant. All of these medications have been routinely used in kidney recipients here at Northwestern University. Belatacept (the "study drug") has been approved by the FDA for use at the time of transplant. However, the use of belatacept in this study is considered investigational as it has not been FDA approved for use beginning at 3 months after transplant. This study will involve 51 adult kidney transplant recipients at Northwestern.

The purpose of this study is to evaluate the efficacy and safety of febuxostat 40 mg extended release (XR) and 80 mg XR in comparison with febuxostat 40 mg immediate release (IR) and 80 mg IR, respectively, in gout participants with moderate renal impairment.

Children with chronic kidney disease, even after transplantation, may be at risk for bone problems due to an imbalance of calcium and phosphorus in the blood, especially as their kidneys progressively fail to function. While some drug and diet treatments are available to prevent such bone disease, many children refuse to take them due to bad taste and tummy cramps. If calcium and phosphorus status remain abnormal for a long time, hard crystals can form in the blood vessels, eventually clogging them and resulting in heart problems. Investigators are studying possible new methods to help the kidneys maintain a normal balance of nutrients in the blood which is important for growing healthy bones and the prevention of side effects in blood vessels that can lead to heart disease. One method is to improve the team work of a hormone FGF-23 and a protein called Klotho that together stimulate the kidneys to increase phosphate removal. Investigators propose that this problem may be due to low blood zinc levels which often occur in children with kidney disease. Thus, in this study, investigators propose to first measure zinc in blood from children with chronic kidney disease (CKD) or who have had kidney transplants to assess zinc and phosphate status, the hormone FGF-23 and its assistant Klotho. If zinc status is low, the children will receive zinc supplementation for 3 months. After treatment with zinc, the same blood measurements will be repeated to determine if the zinc supplements have helped the hormones to remove phosphate from the body. If this pilot project is successful, investigators will then consider a larger scale project involving adult patients as well as pediatric patients from other pediatric centers. This project will also guide investigators as to whether they need to introduce zinc measurements as part of routine testing of CKD and transplant patients. In addition to measuring zinc levels in study participants, trace elements (TE) will also be measured. These include heavy metals such as cadmium, chromium, nickel, vanadium, copper, lead, manganese and selenium. Very little is known about levels and metabolism of TE in CKD especially before dialysis. In adults, cadmium, chromium, nickel, and vanadium probably accumulate in hemodialysis patients, while copper and lead may accumulate. Manganese, selenium are probably deficient. The study will allow investigators to obtain the information about TE in this group of pediatric patients.
