A Study of Cidofovir in HIV-Infected Children With Cytomegalovirus (CMV) Disease
Cytomegalovirus InfectionsCytomegalovirus Retinitis1 morePart A: To determine the safety and pharmacokinetics of sequential single doses of cidofovir in HIV-infected children with end-organ cytomegalovirus (CMV) disease. Part B: To determine the safety (including time to progression of CMV retinitis by retinal exam), pharmacokinetics, and long-term (6 months) tolerance of multiple-dose cidofovir in HIV-infected children with CMV retinitis. Part B: To determine the effect of multiple-dose cidofovir on the virologic parameters of CMV retinitis (viral load, shedding, and resistance to antiviral agents). [AS PER AMENDMENT 1/7/98: To determine the safety, tolerance and pharmacokinetics of sequential single doses of cidofovir in HIV-infected children with CMV retinitis. To determine the safety (including time to progression of CMV retinitis by retinal exam), pharmacokinetics, and long-term (6-month) tolerance of multiple doses of cidofovir in HIV-infected children with CMV retinitis.] While the intravenous formulation of cidofovir has been approved for the treatment of CMV retinitis in HIV-infected individuals, information is limited regarding its safety and tolerance in HIV-infected children. Intravenous cidofovir requires less frequent administration for both induction and maintenance therapy of CMV retinitis than other currently available therapies. If found to be safe and well tolerated in HIV-infected children with CMV retinitis, intravenous cidofovir would add significantly to agents available to treat this debilitating opportunistic infection.
Reducing Acquisition of CMV Through Antenatal Education
Cytomegalovirus CongenitalThe evidence to date indicates that educational strategies may be effective at reducing antenatal CMV infection, however these have not been tested in the UK. In phase 1 of the study, the investigators will co-design an educational intervention with pregnant women and families affected by congenital CMV with the aim of reducing the risk of acquisition of CMV in pregnancy. In phase 2 of the study, the investigators will use this educational intervention in a randomised controlled trial (RCT) as part of a feasibility study to generate the data required for the design of a future main RCT. Should the future main RCT show that the educational intervention is effective in reducing the risk of primary CMV infection in pregnancy, the intervention could be rolled out in the National Health Service (NHS). This would have significant benefits to patients and the NHS. No other single cause of congenital defects and long-term developmental disability currently provides greater opportunity for improved outcomes than the prevention of congenital CMV, therefore trials designed to test prevention strategies should be a research priority for the NHS.

Cytomegalovirus InfectionCytomegalovirus DiseaseThis 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.
Trial to Evaluate Safety and Immunogenicity of a Vaccine Against HCMV
Cytomegalovirus InfectionThe objectives of this first-in-human is to evaluate the safety and the immunogenicity of three administrations of a bivalent vaccine candidate against human cytomegalovirus, at three different dose levels.
A Study to Evaluate the Efficacy and Safety of a Vaccine, ASP0113, in Cytomegalovirus (CMV)-Seronegative...
Kidney Transplantation Cytomegalovirus (CMV) Negative RecipientsThe purpose of this study was to evaluate the efficacy of ASP0113 compared to placebo in reducing the incidence of cytomegalovirus (CMV) viremia in CMV-seronegative subjects receiving a kidney from a CMV-seropositive donor. This study also evaluated the safety of ASP0113 in this patient population.
ValGanciclovir Versus ValAcyclovir for Viral Prophylaxis in Kidney Transplantation
Transplantation InfectionEpstein-Barr Virus Infections1 moreOur study will compare all kidney transplant recipients receiving valganciclovir vs. valacyclovir for one year following kidney transplant and compare: the incidence, magnitude and duration of CMV and EBV viremia in the first year after transplant. the side effects of the anti-viral drugs requiring dose reduction or cessation In addition, we will test renal tissue obtained from any biopsies post-transplant (surveillance or clinically indicated biopsies) by both polymerase chain reaction (PCR) and fluorescence in situ hybridization to assess for latent CMV and/or EBV.
An Evaluation of a Cytomegalovirus (CMV) Vaccine (ASP0113) in CMV-Seropositive and CMV-Seronegative...
DialysisHealthy Subjects1 moreThe purpose of the study is to determine whether ASP0113 (a CMV deoxyribonucleic acid [DNA] vaccine) can be detected in plasma after intramuscular (IM) injections, and to determine whether CMV-seropositive healthy volunteers, CMV-seronegative healthy volunteers, CMV-seronegative dialysis patients mount an immune response to the CMV proteins produced by the vaccine after repeated ASP0113 IM injection.
A Randomized Trial to Prevent Congenital Cytomegalovirus (CMV)
Congenital Cytomegalovirus InfectionMaternal Cytomegalovirus InfectionCytomegalovirus (CMV) is a common virus that usually presents with few if any side effects. When first infected, some people may have symptoms similar to mononucleosis (i.e., fatigue, weakness, fever, swollen glands). Most people in the United States are infected during childhood or as adults if they work around children. Pregnant women, who have not been infected with CMV in the past and become infected during pregnancy (i.e. a primary infection), may cause their babies to get infected with CMV. Babies that are infected may develop permanent disabilities including hearing loss and a small portion will die from the infection. Currently it is not routine practice to screen pregnant women for CMV infection. Additionally, there is no agreement about how to evaluate and manage pregnant women infected with CMV for the first time. There is also no evidence that treatment is beneficial for the baby. The purpose of this research study is to determine whether treating pregnant women who have a primary CMV infection with CMV antibodies will reduce the number of babies infected with CMV.
Letermovir (MK-8228) Versus Placebo in the Prevention of Clinically-Significant Cytomegalovirus...
Prevention of CMV Infection or DiseaseThe study evaluated the efficacy and safety of letermovir (MK-8228) for the prevention of clinically-significant CMV infection in adult, CMV-seropositive recipients of allogeneic hematopoietic stem cell transplant (HSCT). The hypothesis being tested was that MK-8228 is superior to placebo in the prevention of clinically-significant CMV infection through Week 24 post-transplant.
