Active clinical trials for "Cytomegalovirus Infections"

The purpose of this study is to evaluate how ganciclovir is metabolized when administered intravenously (by a needle inserted into a vein) following valganciclovir syrup, given by mouth to newborns and young infants with symptoms of congenital (present at birth) cytomegalovirus (CMV) disease. The study also seeks to identify a dose of valganciclovir that provides a comparable blood concentration to ganciclovir present in the blood of newborns with symptomatic congenital CMV disease. All study participants will receive 6 weeks of antiviral therapy (defined as ganciclovir and/or valganciclovir). Infants from 0 to 30 days old will participate in the study for 2 years.

This study will assess the safety and pharmacokinetics of Valcyte syrup in pediatric solid organ transplant recipients. The anticipated time on study treatment is 3-12 months and the target sample size is less than 100 individuals.

The purpose of this study is to evaluate the benefits and safety of the antiviral drug ganciclovir (DHPG) given intravenously to treat newborn infants who are born infected with cytomegalovirus (CMV). CMV is a herpes virus that can infect most organs of the body, resulting in death in 10-30% of babies with symptoms of CMV. It can cause severe brain damage in a large percentage of surviving babies. Children in this study have a CMV infection of the central nervous system (CNS).

This study will assess the relative bioavailability of ganciclovir from the pro-drug valganciclovir in lung transplant recipients with or without cystic fibrosis. Each patient will receive 900mg valganciclovir daily for the period specified at their center, starting as soon as possible after the transplant. Pharmacokinetic assessments will be made provided that steady-state kinetics of ganciclovir and immunosuppressive drugs have been obtained (>=4 days of drug therapy). Blood samples for pharmacokinetic analysis will be taken up to 24h post-dose on one occasion. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

To evaluate the clinical and laboratory toxicity of ganciclovir (GCV) and zidovudine (AZT) when given in combination. Because recent information has shown AZT to be useful in treating AIDS, it is assumed that most patients with AIDS, and probably with AIDS related complex (ARC), will be receiving AZT. Because AZT is reported not to be active against cytomegalovirus (CMV), it is important to see if it is useful to give GCV along with AZT.

The main purpose of this project is to evaluate the efficiency of the injection of CD4 and CD8+ T cell anti-Cytomegalovirus (CMV) on blood viral replication of CMV, 21 days after the first injection (adenovirus infection is not enough usual, especially in adults, to be used for the primary purpose and is measured in the secondary endpoints).

Hardening of the arteries (atherosclerosis) and heart disease are much more common in men than in women. However, as women grow older, especially after menopause the incidence of atherosclerosis and heart disease increases. These findings suggest that estrogen may be protective and help in preventing heart disease. Studies of large groups of post-menopausal women suggest that hormone replacement therapy (therapy that includes estrogen) reduces the risk of heart disease. Estrogen causes favorable changes in particles that carry cholesterol in the blood stream and improves function of blood vessels. Estrogen may also stimulate the immune system's ability to fight off infections that may lead to or contribute to atherosclerosis. Researchers believe two specific infectious agents (Chlamydia pneumoniae and human cytomegalovirus) may cause damage to the lining of blood vessels resulting in inflammation and the development of atherosclerosis. The purpose of this study is to determine if estrogen treatment can change how the immune system responds to chronic infections, by Chlamydia pneumoniae and human cytomegalovirus, in postmenopausal women.

The purpose of this study is to see how well transfusions of T-cells work in treating CMV. T-cells are a type of white blood cell that helps protect the body from infection. A transfusion is the process by which blood from one person is transferred to the blood of another. In this case, the T-cells are made from the blood of donors who are immune to CMV. The T-cells are then grown and taught to attack the CMV virus in a lab.

The objective of the trial is to investigate whether early treatment with oral valganciclovir of infants with both congenital cytomegalovirus infection and sensorineural hearing loss can prevent progression of hearing loss.

Cytomegalovirus (CMV) infections remain an important cause of morbidity and mortality in allogeneic hematopoietic cell transplant (HSCT) recipients, especially in patients received haploidentical transplantation. During the past decades, prophylactic or preemptive treatment with antiviral drugs has significantly reduce the incidence of early-onset CMV infection. Unfortunately, prolonged antiviral treatment is associated with substantial toxicity and may delay recovery of virus specific immune responses, resulting in an increasing of late-onset CMV disease. To date, adoptive immunotherapies have been developed as treatment alternatives to antiviral agents for CMV infection after HSCT. Studies have demonstrated that prophylactic or preemptive therapy with donor CMV-specific T cells can restore antiviral immunity and clear CMV viremia after transplantation. In this prospective clinical phase I/II trial, we propose to reconstitute antiviral immunity against CMV by preemptive transfer of CMV-specific T cells at an early time point after allogeneic stem cell transplantation. We also propose to demonstrate whether protect against CMV is associated with recovery of CMV-specific T cells.
