Filter by:This is an open label trial in which letermovir will be given as prophylaxis for the prevention of CMV infection and disease to all heart transplants who are at risk for cytomegalovirus. The study will compare a 30 patient prospective cohort to a retrospective cohort of 374 heart transplant recipients for the rates of neutropenia. In addition, the tolerability of letermovir will be assessed in this population.
The primary objective is to assess the efficacy and safety of NPC-21 when administered prophylactically to cytomegalovirus (CMV) seronegative patients receiving a first kidney transplant from a CMV seropositive donor.
This study aims to evaluate the safety, efficacy and pharmacokinetics (PK) of Letermovir (LET) administered as prevention of cytomegalovirus (CMV) infection and disease in adult Japanese kidney transplant recipients.
To compare the efficacy of oral brincidofovir (BCV) to valganciclovir (vGCV) for the prevention of cytomegalovirus (CMV) disease in kidney transplant allograft recipients who are CMV seronegative pretransplant and received a kidney from a CMV seropositive donor
This was a randomized, double-blind, double-dummy, parallel-group, multicenter study of the efficacy, safety, and tolerability of oral brincidofovir (BCV) versus valganciclovir for the prevention of cytomegalovirus (CMV) disease in CMV-seropositive kidney transplant recipients who received antilymphocyte induction therapy.
CMV disease is a challenge to the success of renal transplantation. Recently, the investigators analyzed data from 792 renal transplant recipients performed at our hospital between 1999 and 2005. After the usual exclusions, 663 patients were analyzed. This population showed that the incidence of CMV disease is stable and occurs in approximately 20-22% of all patients and invasive disease in approximately 5% every year. In seronegative patients and those receiving anti-lymphocyte (AL), CMV prophylaxis, done with ganciclovir for 90 days is our routine and in the majority of transplant centers. In seropositive patients without associated risk factors (such as the use of AL) universal prophylaxis is not done. Rather, in this group, early diagnosis, by detection of antigenemia or viremia by quantitative PCR, is performed in patients who show symptoms compatible with CMV disease. In the investigators analysis the incidence of CMV disease in seropositive patients is around 16%. These patients are usually hospitalized and treated with GCV IV for 14-21 days. This leads to an additional costs of admissions, biopsies for the diagnosis of disease invasion, etc. Besides these costs, the survival of the grafts in the long run is lower in patients with CMV disease than in those without CMV, particularly when associated with acute rejection. In recent years, monitoring of viremia (PCR / antigenemia) and preemptive treatment when it reaches substantial values, have increasingly been suggested. Patients in whom the detection of viremia in progressive values is detected would be treated as outpatients before the disease develops. To turn this hypothesis into reality, there is an urgent need to define cutoff values for CMV-PCR in the detection of developing CMV disease.
The purpose of the study is to assess the incidence and severity of late Cytomegalovirus (CMV) disease, defined as CMV syndrome or tissue invasive disease occurring between 100 and 200 days and after 200 days post-transplant in patients treated with valganciclovir per package insert guidelines for prophylaxis against CMV infection for 200 days post-transplant versus valganciclovir per package insert guidelines for 100 days post-transplant with Cytogam 100 mg/kg administered at 90 days, 120 days, and 180 days post-transplant.
The spread of viruses through transfusions is the cause of serious illness and death in recipients whose immune systems are unable to fight infection. Another group of patients whose immune systems are underdeveloped and can be affected by a particular virus known as cytomegalovirus (CMV) is low birthweight infants (LBWIs). CMV can be spread through the placenta, during the birth process, through breast milk, while in the hospital or while caring for someone carrying the virus as well as through a transfusion, known as transfusion-transmitted (TT-CMV). The spread of TT-CMV in LBWIs can be curtailed by transfusing blood products that are CMV negative as well as to filter the white cells in blood that carry the virus (leukoreduction). The purpose of this study is to see if the use of these two strategies can lower the spread of CMV through a transfusion. How "safe" the blood actually is through leukoreduction is not known and CMV still occurs in LBWIs. It is not clear whether this approach is optimal or whether additional safety steps are needed to completely prevent TT-CMV. Specific actions that could tell us when virus has reached the blood product or breast milk is to test each of these to determine if virus slipped "unnoticed" and/or when the product was not thoroughly filtered. In this study, the investigators believe that the use of both prevention strategies will result in a lower rate of TT-CMV, and that the "cause" of TT-CMV may be found in the presence of CMV at the DNA level or by unfiltered white cells that remain in the blood product. Thus, the most significant clinical question that remains to be addressed is whether this double strategy for transfusion safety actually provides a "zero CMV-risk" blood supply or whether further safety measures (DNA testing + 100% leukoreduction) must be used to protect this extremely vulnerable patient group from CMV infection. This birth cohort study will be done with 6 participating NICUs, and will study both CMV positive and negative mothers in order to estimate the rate and pathway of CMV transmission to the LBWI who receives a transfusion. Another study goal is to compare or link any CMV infection by either transfused units where the virus was undetected, or filter failure. If CMV disease occurs, the investigators will be able to describe the course and outcome in LBWIs who develop TT-CMV.
A prospective, randomized safety and efficacy study of Certican® as add-on therapy against CMV disease in renal transplant recipients OBJECTIVES: Primary Objective: To demonstrate efficacy of Certican® as add-on therapy against CMV disease in comparison to either valcyte® (valganciclovir) or cymevene® (ganciclovir) alone, evaluated by quantitative measurement of CMV-DNA with PCR from the blood (qCMV-PCR) Secondary Objectives: To assess safety and tolerability of Certican® in patients with CMV- disease To study the effects of Certican® treatment on quality of life
