Filter by:The purpose of this study is to test the safety of a transfusion of specialized white cells from your transplant donor's blood, called T-cells, that have been grown and immunized against the CMV virus in the test tube. If the transplant donor is immune to CMV (ie: the donor has antibody to CMV in the blood), the T-cells will be selected and grown from the blood of the transplant donor. However, if the transplant donor is not immune to CMV, or if T-cells from the donor are not readily available, CMV-immune T-cells grown from the blood of another normal donor who is partially matched to the patients tissue type can be used. The transplant physician will explain which of these treatments is available to the patient. This trial is called a phase I trial because phase I trials are designed to test the safety of different doses of an experimental treatment. We want to find out what effects, good and/or bad, a dose/doses of these immune T-cells will have on the patient and on the CMV infection. Specifically, we wish to test CMV immune T-cells grown from your blood using a new method developed at our center. In this method, fragments of an important CMV protein, called CMVpp65, are chemically synthesized and then used to immunize T-cells in the test tube.
This study examines the immunologic and virologic effects of prophylactic CMV specific CTL in recipients of T cell depleted stem cell transplant (TCD SCT) at Duke University Medical Center (DUMC), by measuring levels of CMV DNA and virus specific T cell precursors at intervals post-infusion.
21 patients were randomised to receive instructions and coaching or no intervention on the use and intake of ganciclovir. Intake of medication was measured by an electronic pill box. The duration of the study was 100 days.
RATIONALE: Vaccines may help the body build an effective immune response to kill cytomegalovirus infections. PURPOSE: This phase I trial is studying the side effects and best dose of vaccine therapy in treating patients who have undergone a donor stem cell transplant and have cytomegalovirus infection that has not responded to therapy.
The purpose of this research study is to investigate whether or not oral maribavir is safe and effective compared to oral ganciclovir for preventing CMV disease when administered for up to 14 weeks in patients who have had a liver transplant.
Cytomegalovirus (CMV) infection is known to cause hearing loss and mental retardation. The purpose of this study is to compare a 6-week course to a 6-month course of the drug valganciclovir in babies born with CMV to assess the safety and efficacy of this treatment. Participants will include 104 infants (30 days old or younger) born with CMV disease. All infants will take valganciclovir by mouth for 6 weeks. At the end of the 6 week period, subjects will be assigned by chance to receive either valganciclovir or placebo (inactive substance) to complete the 6 months of antiviral treatment. Patients will be followed for the study related evaluations of safety, changes to hearing, and developmental milestones for up to 2 years. Patients will be followed by telephone contact for an additional 3 years. Thus, participants may be involved in study related procedures for approximately 5 years.
Recent studies indicate that persistent viral infections particularly with Cytomegalovirus (CMV) might have a negative impact on immune senescence (i.e. immunocompetence of elderly individuals). We will test this hypothesis by performing a vaccination trial in healthy elderly individuals subdivided in two groups of CMV-seropositive and CMV-seronegative individuals. All individuals will be vaccinated with the currently licensed vaccine for the prevention of TBE (FSME Immun CC) which is recommended for the general population in our area. Vaccination efficacy will be monitored longitudinally concerning the TBEV-specific antibody (TBEV-neutralization, TBEV-specific ELISA) and T cell response (ELISpot, cytokine production). Vaccination efficacy will be compared between CMV+ and CMV- individuals and correlated with the CMV-specific immune response in CMV+ individuals.
AVX601, a bivalent alphavirus replicon vaccine expressing three CMV proteins (gB, pp65 and IE1) is a candidate vaccine against cytomegalovirus (CMV). The objectives of this Phase 1 study are to test the safety of the vaccine and the immune response to the vaccine in healthy volunteers who have not previously been infected with CMV. Volunteers will be assigned by randomization to receive either the vaccine or an inactive substance (placebo) by injections in each arm on three occasions over 6 months. The study will last 12 months and will have a total of 12 visits.
Cytomegalovirus (CMV) is a common cause of illness in patients who have undergone a transplant. Serious infections due to CMV can affect many parts of the body including the lungs, the gut, and the liver. Since transplant recipients are at risk for CMV or have evidence of infection with CMV, they are given an antiviral drug (usually ganciclovir or valganciclovir). Despite this, there are a chance that CMV infection may cause problems in the future. The purpose of this study is to assess how well patients'immune systems responds to the CMV virus, so that in the future it may be possible to predict which patients are at highest risk of CMV.
This will be the first time in humans (FTIH) study with the GSK Bio recombinant gB antigen to evaluate safety and immunogenicity of this CMV candidate vaccine with a proprietary GSK adjuvant system. The vaccine will be administered to young male healthy subjects at 0, 1 and 6 months. The trial will assess the safety and immunogenicity of the candidate CMV vaccine. An additional secondary objective of this trial is to identify and validate a test which will be able to differentiate between previous CMV infection and CMV vaccination. Subjects will be followed for a total of 2 years.
