30 Clinical Trials for Various Conditions
This is a multi-center clinical trial in Cytomegalovirus (CMV) seronegative prospective liver transplant recipients to determine the efficacy of two doses of Cytomegalovirus-Modified Vaccinia Ankara (CMV-MVA) Triplex CMV vaccine pre-transplant. The primary objective is to assess the effect of pre-transplant (Tx) Triplex vaccination on duration of CMV antiviral therapy (AVT) within the first 100 days post-Tx in CMV seropositive donor (D+) and seronegative (R-) (D+R-) liver transplant recipients (LTxRs). A protocol-mandated preemptive therapy (PET) will be used for CMV disease prevention in D+R- LTxRs.
Researchers are trying to improve the understanding of systolic function of the heart at the time of liver reperfusion in patients undergoing orthotopic liver transplantation.
Hepatic vein flow (HVF) assessment using transesophageal echocardiography (TEE) has a potential to predict postoperative graft function in orthotopic liver transplant (OLT). Investigators will measure HVF using TEE and assess the correlation with postoperative graft function indices such as early allograft dysfunction(EAD), prolonged INR, platelet, and total bilirubin.
The purpose of this study will be to prospectively evaluate the outcomes of patients with hepatocellular carcinoma (HCC) who undergo DEB-TACE (drug-eluting bead trans-arterial chemoembolization) with the Surefire Precision Infusion System for intentional effect of down-staging patients to OLT. Patients with HCC and who are considered candidates for liver transplantation but outside Milancriteria and meet the eligibility criteria will be enrolled in the prospective single arm study. Results of the prospective cohort will be compared to matched historical control patients who were previously treated with DEB-TACE, delivered with standard endhole catheters. This includes all patients treated at the University of Colorado since 2009 treated with 100-300 micron beads for whom follow-up is available.
The purpose of this study is to evaluate sustained virologic response 12 weeks after the end of treatment (SVR12) following 12 weeks of simeprevir plus sofosbuvir with and without ribavirin (RBV) and 24 weeks of simeprevir plus sofosbuvir without RBV in post orthotopic liver transplant participants with recurrent hepatitis (inflammation of the liver) C virus (HCV) Genotype 1 infection.
This is a double-blind, multicenter study involving patients with chronic HCV infection who had a liver transplantation; developed HCV-related liver fibrosis and/or incomplete cirrhosis; achieved a sustained virologic response (SVR) following anti-HCV therapy; but still have fibrosis and/or incomplete cirrhosis on liver biopsy to see if treatment with IDN-6556 is better than placebo in reversing or stopping the progression of the damage to the new liver caused by HCV.
Post-Marketing Requirement study to evaluate the safety of octaplas™ versus plasma in patients undergoing orthotopic liver transplantation (OLT). The primary objective is to assess the incidence of hyperfibrinolysis in patients undergoing (OLT) receiving octaplas™ versus regular plasma (e.g., fresh frozen plasma and other FDA and AABB approved plasma products).
The purpose of this study is to evaluate the efficacy of an everolimus conversion (EVR) protocol as compared to the standard tacrolimus (TAC) based protocol in liver transplant recipients, as determined by renal function, rejection rates, and progression to fibrosis (in HCV positive subjects). Additionally, safety profile and tolerability of these regimens will be assessed.
Currently, there is no treatment standard for use of anti-HCV (hepatitic C virus) medications for those preparing for a liver transplant. The purpose of this study is to determine whether those individuals who require liver transplantation for Hepatitis C, genotype I, who are undergoing liver transplantation may successfully get rid of their virus before the transplant by taking three medicines, peginterferon, ribavirin, and boceprevir, up until the time of the liver transplant surgery. If successful, the Hepatitis C virus will not re-infect the new liver that they receive and they will not require therapy for Hepatitis C after liver transplantation. This study involves the use of peginterferon alfa-2b, ribavirin, and boceprevir, all of which are approved for the treatment of genotype I Hepatitis C. Hypothesis: The addition of boceprevir to peginterferon alfa-2b and ribavirin in patients with Hepatitis C genotype 1 with or without hepatocellular carcinoma undergoing orthotopic liver transplantation will lead to rapid HCV RNA clearance of genotype I infected individuals. Transplantation with anhepatic boceprevir will prevent reinfection of the new transplanted graft and prevent graft infection posttransplantation.
Patients undergoing orthotopic liver transplant will experience some degree of clinical and/or biochemical hepatic dysfunction. This early injury is known as primary graft dysfunction and varies from minor abnormalities to primary nonfunction. Prostaglandin-class drugs, including prostacyclin and its analogs, could represent an important advance toward the goal of reducing transplant related morbidity, mortality and associated costs by providing these benefits.
To evaluate the efficacy of continuous renal replacement therapy (CRRT) during orthotopic liver transplantation (OLT) in clearing excess solutes and improving acid-base parameters. The investigators hypothesize that the use of intra-operative CRRT in OLT recipients is associated with increased solute removal and improved acid-base statues when compared to controls who do not receive CRRT
Patients are being asked to be part of this study because they are a liver transplant recipient and have the Hepatitis C Virus (HCV). Current routine treatment for HCV for liver transplant patients includes taking two medications called pegylated interferon alfa-2a (Pegasys®) and ribavirin. Patients Pegasys and ribavirin are FDA approved for the treatment of HCV. This study will evaluate the safety and efficacy of adding a third drug called telaprevir for the experimental treatment of HCV in liver transplant patients. The combination of Pegasys, ribavirin and telaprevir is currently FDA approved for the treatment of HCV, but is specifically not FDA approved for HCV patients who have had a liver transplant. This is because more information is needed about possible drug interactions between telaprevir and cyclosporine, or telaprevir and tacrolimus-based immunosuppressive drugs, which are typically part of routine care for transplant patients. Studies have shown that the addition of telaprevir greatly increases the efficacy of Pegasys and ribavirin for the treatment of HCV. However, these studies did not include adequate information on transplant patients due to the potential drug interactions. The investigators hope to gather more information about the safety and efficacy of telaprevir given in combination with Pegasys and ribavirin in the liver transplant patients who have HCV that is not well controlled with Pegasys and ribavirin alone.
The purpose of this study is to investigate the effect of two different doses of vitamin D3 (2000 IU vs. 4000 IU) on serum 25-hydroxyvitamin D (25OHD) levels in patients with hepatocellular carcinoma on the liver transplant list. The study will help determine the dose of vitamin D3 that is required for patients with liver cancer to reach a normal level of 25OHD in the blood.
The overall purpose of this study is to evaluate the safety, pharmacokinetics and preliminary efficacy of a five-days post-operative course of Treprostinil in liver transplant patients. The hypothesis of this study is that Treprostinil can be safely administered post-operatively in liver transplant patients. Once safety is documented future studies will address its ability to ameliorate or prevent reperfusion mediated dysfunction of the liver graft and thereby reduce morbidity, leading to shorter hospital stays as compared to historical controls.
Patients with either histological confirmation or clinical diagnosis who are candidate for orthotopic liver transplant(OLT) will receive Sorafenib 400mg 2 x day (BID) as a neoadjuvant (bridging) treatment until transplant. If patient progresses or falls outside of the Milan criteria on sorafenib patient can be treated per physician's discretion using local therapy. Patient will be followed until 30 days after the orthotopic liver transplant (OLT).
This study is being done to determine if patients receiving (iNO) will have increased liver function and less damage from IR than patients who do not receive (iNO).
The study is designed to assess the feasibility of evaluating YSPSL for the amelioration of ischemia reperfusion injury following liver transplantation by administering YSPSL into the liver graft directly ex vivo via the portal vein and to the recipient intravenously prior to reperfusion. This study is an extension of the recent pilot study YSPSL-0002 with an almost identical study protocol. The rationale of this and the previous study is based on the recent observation that P-selectin expression has been associated in liver grafts with prolonged cold storage times and rejection. By examining biomarkers of IRI including P-selectin by immunohistochemistry and/or quantitative PCR, liver histology and hepatic blood flow using established techniques, the goal of this study is to evaluate the feasibility of using these modalities for future studies of safety and efficacy.
After a liver transplant, the hepatitis C virus (which destroyed one's own liver) eventually comes back. In many patients, this will eventually cause the loss of the new liver and can also confuse the doctors taking care of them because it is hard to tell the difference between one's body rejecting the new liver and hepatitis. This can cause serious treatment errors that can lead to more severe hepatitis or to rejection of the liver. Some of the drugs used to prevent rejection of one's new liver can cause the hepatitis to come back in a more severe form. This is especially true for the drugs known as corticosteroids. Right now, the only effective treatment against hepatitis C is a combination of two drugs called interferon and ribavirin. These drugs act by strengthening one's immune system to fight the virus and by directly reducing the reproduction of the virus. Because the treatment with these drugs is associated with many side effects, there is little experience with treating patients after liver transplantation with them. In the investigators' transplant program, they have decided to treat all patients with hepatitis C as early as possible after transplantation and to follow them closely for the development of hepatitis and side effects of the treatment. The investigators treat one's hepatitis as early as possible, before any actual damage has occurred in the new liver. This approach has been tried before but it has been hard to tell if it has worked or not. The main reason for failure was that many patients could not complete the treatment due to side effects. The investigators' purpose is to treat those side effects aggressively so that most patients can complete the treatment course. The purpose of this study is to collect all the data regarding the investigators' treatment protocol so that they will be able to learn if this form of treatment is beneficial. The study includes performing liver biopsies at scheduled times after one's liver transplant and for scheduled blood tests to see how much virus is still in the blood. If patients show signs that they are not responding to treatment they will be removed from the study.
The purpose of this study is to: determine the safety of donor right hepatic lobectomy as a procedure to provide a liver graft for living donor liver transplantation. study the regeneration of liver tissue by volumetric testing for both donor and recipient. assess if graft and patient survival with living donor transplantation is comparable to that of cadaveric donor transplantation.
OBJECTIVES: I. Determine the effects of bile externalization and antibiotic gut sterilization on the pharmacokinetics of mycophenolate mofetil in patients who have undergone orthotopic liver transplantation. II. Correlate serum concentrations of mycophenolic acid with inosine monophosphate dehydrogenase activity in these patients.
The primary objective of this study is to demonstrate effectiveness of the WallFlex Biliary RX Fully Covered Stent for anastomotic biliary strictures in post-orthotopic liver transplant (OLT) patients.
A post-treatment follow-up observational study for liver disease subjects with or without liver cirrhosis after receiving emricasan or placebo. Subjects must have been enrolled in a prior IDN-6556 study to be eligible.
The purpose of the study is to investigate the safety and efficacy of oral vancomycin in patients with recurrent Primary Sclerosing Cholangitis (PSC) after liver transplantation. The primary endpoint is looking at the effect of the drug on liver function tests, an important surrogate of PSC disease activity at 12 weeks on treatment. Secondary endpoints include a decrease in liver function tests at 1 year, changes in bilirubin and adverse events. Effective treatment at the onset of PSC recurrence may lead to decreases in disease progression, recurrent liver failure, and repeat liver transplantation.
This study will assess the feasibility of lower limb-ischemia induced Remote Ischemic Conditioning (RIC) in the perioperative period before, during, and after Orthotopic Liver Transplantation (OLT). Remote ischemic conditioning will consist of 3 cycles of 5 minutes of lower limb ischemia induced via a mid-thigh pneumatic tourniquet, followed by 5 minutes of reperfusion. Interventions will take place after anesthesia induction but before surgery, at the completion of the procedure, and on the mornings of post-operative days 1-4.
This study will compare stereotactic body radiation therapy (SBRT) to trans-arterial chemoembolization (TACE) as a bridging strategy for patients with HCC undergoing orthotopic liver transplantation. We propose that SBRT will be associated with longer time intervals between initial treatment and the need for retreatment, compared to TACE, as a "bridge" to orthotopic liver transplantation.
This is an investigator initiated study at the University of California, Los Angeles (UCLA) funded by Novartis looking at using a combination of immunosuppressive drugs in liver transplant patients that are at risk of developing kidney problems. Kidney problems following liver transplants is the most problematic issue facing liver transplant patients today. This study will generate information in this area of high unmet medical need utilizing basiliximab and Myfortic and using a reduced dose of tacrolimus, one of the current standard of care medications, after kidney function has normalized.
HepaGam B Hepatitis B Immune Globulin (HBIG) solution contains 10% maltose, which could possibly interfere with the measurement of glucose levels when using glucose non-specific tests. The purpose of this study is to determine whether use of HepaGam B HBIG shows an increase in glucose levels in the body using non-specific glucose monitoring, as well as specific glucose monitoring. The sponsor believes that this medication will not cause a significant increase in glucose levels in the body when measured by glucose non-specific tests.
The objective of this study is to provide open label emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) for an additional 5 years (240 weeks) to adults completing study GS-US-203-0107.
Liver transplant patients often require multimodal immunosuppressive therapy to minimize their risk for rejection. In our regimen, MMF (mycophenolate mofetil) is often added to lower the side effects of the calcineurin inhibitors. Unfortunately the literature reports 20% up to as many as 40% of patients have GI intolerance to MMF. At our Center, approximately 30% of patients have intolerance to MMF, thereby mitigating our ability to use this agent. The primary objective of this study is to assess the tolerability of myfortic in combination with Neoral or Tacrolimus as determined by the GSRS (Gastrointestinal Symptom Rating Scale) after conversion from MMF in maintenance liver transplant patients with GI intolerance within 3 months.
The objective of this 96-week study was to evaluate the safety and antiviral efficacy of emtricitabine/tenofovir disoproxil fumarate (FTC/TDF, coformulated; Truvada®) with or without hepatitis B immunoglobulin (HBIg) in preventing the recurrence of chronic hepatitis B following liver transplantation, in participants who were chronically infected with hepatitis B prior to transplantation. Prior to enrollment, participants were required to have received at least 12 weeks of HBIg therapy following liver transplantation. Enrolled participants then received FTC/TDF plus HBIg for an initial 24-week pre-randomization treatment period. Participants who completed the pre-randomization period and who achieved sustained viral suppression were randomized to continue treatment with FTC/TDF with or without HBIg for an additional 72 weeks (randomized period). The antiviral efficacy of treatment was assessed by measuring hepatitis B virus levels in the blood (HBV DNA). Safety and tolerability was monitored by assessing adverse events and various laboratory parameters.
