187 Clinical Trials for Various Conditions
This study evaluates the feasibility and accuracy of using saliva to remotely monitor cytomegalovirus (CMV) infection in individuals receiving treatment for ovarian cancer.
The main aim of this study is to find out the safety, tolerability and pharmacokinetics (PK) of maribavir for the treatment of CMV infection in children and teenagers after HSCT or SOT and to identify the optimal dose of maribavir using a 200 milligrams (mg) tablet formulation or powder for oral suspension. The participants will be treated with maribavir for 8 weeks. Participants need to visit their doctor during 12-week follow-up period.
The purpose of this study is to determine of letermovir (LTC) is effective at preventing Cytomegalovirus (CMV) infection from returning in people who have already had CMV infection after a bone marrow transplant.
The purpose of this study was to evaluate the safety and efficacy of letermovir (LET) versus placebo when cytomegalovirus (CMV) prophylaxis was extended from 100 days to 200 days post-transplant in CMV seropositive participants who received an allogenic hematopoietic stem cell transplant (HSCT). It was hypothesized that LET is superior to placebo in the prevention of clinically-significant CMV infection when LET prophylaxis is extended from 100 to 200 days.
The present trial will consist of the treatment of 20 pediatric and adult Hematopoietic Stem Cell Transplantation (HSCT) recipients or immunocompromised participants diagnosed with opportunistic Cytomegalovirus (CMV) infections with virus-specific, antigen-selected T-cells. CMV-specific T-cells will be isolated from donor leukapheresis products using the CliniMACS® Prodigy. Prior studies on transfer of CMV specific T-cells have been shown to be safe and efficacious in the treatment of CMV infections. The main trial objective is to evaluate the feasibility and safety of CMV-specific T-cell transfer in adult and pediatric participants suffering from CMV infections or reactivation following HSCT or due to other immunocompromised states (e.g.; primary immunodeficiency, cytotoxic therapy). Participants will be followed for one year.
The purpose of this study is to compare the efficacy of maribavir to investigator-assigned anti-Cytomegalovirus (CMV) therapy in CMV viremia clearance in transplant recipients who are refractory or resistant to prior anti-CMV treatment.
RATIONALE: Infection prophylaxis and management may help prevent cytomegalovirus (CMV) infection caused by a stem cell transplant. PURPOSE:This clinical trial studies infection prophylaxis and management in treating cytomegalovirus infection in patients with hematologic malignancies previously treated with donor stem cell transplant.
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.
The purpose of this study is to determine if (recurrent) cytomegalovirus (CMV) infection of the mother results in pregnancy complications such as preterm delivery, severe preeclampsia, poor fetal growth, or stillbirth.
The purpose of this study is to determine if detection of cytomegalovirus (CMV) in amniotic fluid collected in the second trimester of pregnancy is associated with pregnancy complications such as preterm delivery or severe preeclampsia.
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).
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.
Cytomegalovirus (CMV) is a significant opportunistic pathogen and a major cause of morbidity and mortality in solid organ transplant recipients. CytoGam - Cytomegalovirus Immune Globulin Intravenous (CMV-IGIV), is an immunoglobulin G containing a standardized amount of antibody against CMV. CytoGam is obtained from pooled adult human plasma that has been selected for high anti-CMV titers. This study will evaluate if administration of CytoGam to organ transplant recipients with CMV infection, along with standard of care antiviral medication, leads to faster clearance of CMV from the blood, prevents the development of antiviral resistance, and decreases the rate of recurrence of CMV infection.
The primary objective of this study is to evaluate the pharmacokinetics (PK) of letermovir (LET) in pediatric participants. Participants will be enrolled in the following 3 age groups: Age Group 1: From 12 to \<18 years of age (adolescents); Age Group 2: From 2 to \<12 years of age (children); and Age Group 3: From birth to \<2 years of age (neonates, infants and toddlers). All participants will receive open label LET for 14 weeks (\~100 days) post-transplant, with doses based on body weight and age.
HB-101 is a bivalent recombinant vaccine against human CMV infection. This is a randomized, placebo-controlled, phase 2 study to assess the safety, reactogenicity, immunogenicity, and efficacy of HB-101 in CMV-Seronegative patients receiving a kidney transplant from a CMV-Seropositive living donor and CMV-Seropositive patients.Patients enrolled should have a living donor kidney transplantation ideally planned between two to four months after the first injection of study drug (HB-101 or placebo).
This study evaluated the safety, tolerability, and efficacy of the cytomegalovirus (CMV) vaccine (V160) administered in a 2-dose or 3-dose regimen to healthy seronegative women 16 to 35 years of age. Participants received blinded V160 on Day 1, Month 2, and Month 6 (3-dose regimen), V160 on Day 1 and Month 6 and placebo at Month 2 (2-dose regimen), or placebo on Day 1, Month 2, and Month 6, and were followed to approximately Month 24. The primary hypothesis of the study was that administration of a 3-dose regimen of V160 will reduce the incidence of primary CMV infection compared to placebo.
This study will determine the relative efficacy and safety of up to 100 days Valcyte prophylaxis relative to up to 200 days Valcyte prophylaxis when given for the prevention of CMV disease in high-risk (D+/R-) kidney allograft recipients. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.
This phase Ib trial evaluates the safety and most effective dose of a cytomegalovirus (CMV) pp65 peptide-loaded alpha-type-1 polarized dendritic cell (CMV-alphaDC1) vaccination in patients who are undergoing an allogeneic hematopoietic stem cell transplant. CMV is an opportunistic infection that can occur or reactivate after allogeneic hematopoietic stem cell transplant as a result of immunosuppression. The CMV-alphaDC1 vaccine is made of white blood cells that have been exposed to molecules called cytokines, as well as CMV proteins. Introducing these dendritic cells to the patients immune system may activate an immune response to CMV, protecting against infection or reactivation.
The purpose of this study is to evaluate the clinical outcomes of Cytomegalovirus (CMV) virus in the participants' body. Therefore, the study team will follow the participants' immunological response based on the Cytomegalovirus (CMV) virus testing.
The goal of STAGE I of the CMV TransmIT Study is to determine the prevalence of CMV shedding in children up to and including 36 months of age in large group childcare centers and in staff who regularly work at the center. Participants will complete a health survey and provide one saliva sample for CMV PCR testing. In addition, infrastructure for the study will be developed (e.g. community engagement to build the network of centers, data pipelines, digital platform, sampling workflows) and participant sample collection at home will be piloted. These activities will inform the design of STAGE II.
The main purpose of the study is to evaluate the efficacy and safety of mRNA-1647 compared to placebo to prevent first clinically significant cytomegalovirus infection (CS-CMVi) in the period following cessation of CMV prophylactic treatment (for example, letermovir) on Day 100 post-HCT through Month 9 post-HCT.
The main objective of this study is to evaluate the safety, reactogenicity, and immunogenicity of the mRNA-1647 vaccine administered according to a 3-study injection schedule in healthy cytomegalovirus (CMV)-seronegative and CMV-seropositive Japanese adults 18 to 40 years of age in the United States.
Participants will be randomized in a 2:1 ratio to receive either two injections of CMV-MVA Triplex® or placebo administered at study Entry/Day 0 and week 4. Vaccine Group: 60 participants will receive CMV-MVA Triplex® containing 5 x 10\^8 plaque-forming unit (pfu) ±0.5 x 10\^8 pfu of MVA Vaccine Encoding CMV Antigens by intramuscular (IM) deltoid injections. Placebo Group: 30 participants will receive a volume of placebo (7.5% Lactose in phosphate-buffered saline \[PBS\]) that matches the volume of the active vaccine injection by IM deltoid injections.
The main purpose of this study is to evaluate the efficacy of mRNA 1647 vaccine in CMV-seronegative female participants and to evaluate the safety and reactogenicity of mRNA-1647 vaccine in all participants. The purpose of the Phase 3 extension sub study is to extend the observation period of the main study and to evaluate the longer-term immune persistence of mRNA-1647 vaccine administered to CMV-seronegative females who complete mRNA-1647-P301 main study and to assess for CMV seroconversion in CMV-seronegative participants who did not seroconvert during mRNA-1647-P301 main study. No interventional vaccine will be administered in the extension study.
The main purpose of the extension phase of this study is to evaluate the longer-term immune persistence of mRNA-1647 vaccine administered to CMV-seronegative and CMV-seropositive adults who completed Study mRNA-1647-P202 (NCT04232280). For participants in the optional booster phase (BP), the main purpose is to evaluate the long-term immunogenicity and safety of the mRNA-1647 vaccine in both participants receiving a booster dose (BD) and those not receiving a BD, and to additionally evaluate the reactogenicity in participants receiving a BD.
This was an open-label, controlled study, conducted at US sites to evaluate the anti-inflammatory effectiveness of the study drug letermovir in adults with HIV and asymptomatic cytomegalovirus (CMV) who were on antiretroviral therapy (ART)-mediated suppression. Participants were randomly assigned to receive either letermovir once daily or no anti-CMV treatment, for 48 weeks. The primary hypothesis of this study was that letermovir would cause a greater reduction in plasma soluble receptor for tumor necrosis factor type II (sTNFRII) levels than no anti-CMV treatment at weeks 46/48.
This study will evaluate whether a brief prenatal clinic-based cytomegalovirus (CMV) risk-reduction behavioral intervention will prevent maternal CMV infections during pregnancy in women.
The primary objective is to determine the incidence of CMV viremia and disease in pediatric allogeneic stem cell transplantation recipients who received ganciclovir prophylaxis up until day +100 by retrospective analysis.
This clinical study will assess the safety and immunogenicity of 3 dose levels of mRNA-1647 cytomegalovirus vaccine in CMV-seronegative and CMV-seropositive healthy adults 18-40 years of age.
The purpose of this study is to use VSTs (virus-specific T cells) from a donor that is a partial HLA (human leukocyte antigen) match with the patient to treat viral infections after an allogeneic hematopoietic stem cell transplant (HSCT). These cells may also have value in CAR-T recipients who have received a product that depletes virus specific T cells. The patient must have had a myeloablative or non-myeloablative allogeneic HSCT using either bone marrow, single/double umbilical cord blood, or peripheral blood stem cells (PBSC) or CAR T cell product targeting an antigen expressed on virus specific T cells. After a transplant, while the immune system grows back, the patient is at risk for infection. Some viruses can stay in the body for life and are normally controlled by a healthy immune system, but if the immune system is weakened, like after a transplant, they can cause life threatening infections. He/she must have had an infection with one or more of the following viruses -Epstein Barr virus (EBV), cytomegalovirus (CMV), adenovirus (AdV), Human polyomavirus type I (BKV), and human polyomavirus type II (JCV)- that has persisted or recurred despite standard therapy. In this study, the investigators want to use white blood cells that have been trained to treat viral infections. In an earlier study the investigators showed that treatment with such specially trained T cells has been successful when the cells are made from the transplant donor. However as it takes 1-2 months to make the cells, that approach is not practical for patients who already have an infection. In a subsequent study, the investigators were able to create multivirus-specific T cells (VSTs) from the blood of healthy donors and created a bank of these cells. The investigators then successfully used these banked cells to treat virus infections after a stem cell transplant. In this study the investigators have further modified their production method to decrease the potential side effects and the investigators want to find out if they can use these banked VSTs to fight infections caused by the viruses mentioned above.
