Active clinical trials for "Adenoviridae Infections"

The investigators will evaluate the safety of a single endovenous infusion of ICOVIR5 in adults with locally advanced and metastatic melanoma. ICOVIR5 consists in a conditionally replicative or oncolytic adenovirus.

This study was designed to assess the safety and efficacy of preemptive treatment with oral brincidofovir (BCV), as compared to placebo, for the prevention of adenovirus (AdV) disease in recipients of hematopoietic stem cell transplantation (HCT) with asymptomatic AdV viremia.

In the Netherlands a 2 center investigator-driven phase I/II clinical trial is initiated in June 2010 testing the oncolytic adenovirus Delta24-RGD to treat glioblastoma patients. The virus is administrated using convection-enhanced delivery by 4 catheters as delivery technique, targeting solid tumor as well as infiltrated tumor cells within the peri-tumoral brain. Patients will be enrolled in cohorts of 3 per dose-level. The dose levels to be explored are: 10^7, 10^8, 10^9, 10^10, 3*10^10 and 10^11 viral particles (vp). Once the MTD has been determined, or the study has reached the highest dose cohort, a further 6 or 9 patients will be enrolled at the MTD and evaluated for safety and preliminary signs of efficacy, such that in total at least 12 patients have received the MTD. The primary objective is to determine the safety and tolerability of Delta-24-RGD administered by CED to the tumor and the surrounding infiltrated brain in patients with recurrent GBM. Secondary objectives are to determine the Progression Free Survival (PFS), Overall Survival (OS), and tumor response rate in patients with recurring tumors amenable for surgical resection and treated at the MTD. Cerebrospinal fluid as well as brain interstitial fluid by microdialysis next to the routinely collected samples of blood at various timepoints before, during and after virus infusion. Various neurodegenerative biomarkers as well as markers of immune response will be assessed in these samples. Furthermore extensive sampling and PCR analyses will be performed to evaluate distribution and shedding of the virus.

Human Adenovirus-specific T-cells can persist and augment impaired adenovirus immune response post allogeneic haematopoietic stem cell transplant, and reduce the requirement for antiviral therapy without toxicity or increasing the occurrence of Graft Versus Host Disease. This is a Phase I/IIa open-label safety study, assessing the effects of administering adenovirus-specific T-cells (Cytovir ADV) to paediatric patients post haematopoietic stem cell transplant.

Patient's on this protocol have a type of blood cell cancer, other blood disease or a genetic disease and have received a stem cell transplant. The donor of the stem cells was either a brother or sister, another relative, or a closely matched unrelated donor. The patient is being asked to participate in this study which tests if blood cells from the donor that have been grown in a special way, can prevent or be an effective treatment for early infection by three viruses - Epstein Barr virus (EBV), cytomegalovirus (CMV) and adenovirus. Adenovirus is a virus that usually causes symptoms of a common cold, but can cause serious life-threatening infections in patients who have weak immune systems. It can affect the lungs and cause very serious pneumonia, and can also damage the gut, liver, pancreas and eyes.CMV can also cause serious infections in patients with weak or suppressed immune systems. It usually affects the lungs, causing a very serious pneumonia, but it can also affect the gut, the liver and the eyes. Approximately 2/3 of normal people harbor this virus in their body. In healthy people CMV rarely causes any problems because the immune system can keep it under control, but after a transplant, the risk of developing CMV disease is much higher because the immune system is so weak. EBV is the virus that causes glandular fever. It is also a life long infection like CMV that is normally controlled by the immune system. When immunity is weak, the virus can become active and cause fevers, enlarged lymph nodes and sometimes a type of cancer called lymphoma. Investigators want to see if a kind of white blood cell called T lymphocytes (T cells)can be used to prevent and treat adenovirus, CMV and EBV in the early stages of reactivation or infection. T cells have been grown from the patient's stem cell donor in the laboratory in a way that will train them to recognize the virus and control it when they are given after a transplant. This treatment with specially trained T cells (also called CTLs) has had activity against these viruses in previous studies and in this study investigators want to see if they still have activity when they are made in a simpler and faster way. These donor-derived multivirus-specific special cell lines are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to evaluate whether donor-derived multivirus-specific special cell lines are safe and can control three viruses: EBV, CMV and adenovirus.

The purpose of this Phase 1 study is to evaluate the safety and immune responses of a new tuberculosis vaccine, Ad5Ag85A, administered to healthy volunteers. 48 subjects will be recruited, 24 who have previously been vaccinated with BCG and 24 who have not received BCG vaccine. Two doses of the vaccine will be compared.

With this study, we want to see if we can use a kind of white blood cell called T cells to prevent or treat AdV and CMV infection. We will grow these T cells from the cord blood before the patients transplant. These cells have been trained to attack adenovirus/CMV-infected cells and are called Adenoviral/CMV-specific cytotoxic (killer) T-cells or "AdV/CMV-CTL." We would plan to give the patient one dose of AdV/CMV-CTL any time from 30 days after their transplant. We have used T cells made in this way from the blood of donors to prevent infections in patients who are getting a bone marrow or blood stem cell transplant but this will be the first time we make them from cord blood.

The main purpose of this study is to see if these T-lymphocytes are safe. To make these Ad-specific T lymphocytes the investigators will obtain blood from the stem cell donor and transfer Ad into another type of blood cell, called monocytes. These cells can then stimulate the T lymphocytes and train them to kill cells infected with Ad. The investigators will then grow these Ad-specific T lymphocytes by more stimulation with Ad-infected monocytes and a third type of blood cell called a B lymphoblast from the donor. After testing the T -lymphocytes, the investigators will inject them into patients after transplant who are at high risk of serious Ad virus infection. The investigators will make sure the injected cells are safe and see if they affect the growth and behavior of adenoviruses in the patient's own body.

This was a Phase 3 open-label, non-randomized, multicenter study of oral brincidofovir (BCV) administered twice weekly for the treatment of adenovirus (AdV) infection detected during asymptomatic AdV viremia or during symptomatic AdV infection.

The investigators are conducting this study because the patient have an eye infection which is called adenoviral conjunctivitis, and is the most common cause of "pink eye". There is currently no treatment for this condition. However, the researchers associated with this study want to understand if using a product called Zirgan, which is a topical ointment that is already FDA-approved for other types of eye infections, will help with the type of infection that the patient currently have. Zirgan is not FDA-approved to treat your type of eye infection. Your participation in this study is expected to last 21 days but the patient will only apply the topical ointment for 14 of those days. During the study, the patient will be asked to come into this clinic 8 times. The purpose of this study is to determine whether topical Zirgan can reduce days that the patient suffers from the eye infection, and also to see if it can prevent the infection from spreading to your second eye and to also see if it can prevent the spreading of the infection to people that the patient come in close contact with. Zirgan will be compared to Genteal Gel in this trial. Genteal Gel is a non-prescription eye lubricant gel and is commonly used for treatment of dry eye. The patient will be asked to apply a topical ointment (either Zirgan or Genteal gel 5 times a day for the first 7 days and then 3 times a day for the following 7 days. The patient will be asked to return to the clinic 21 days after the patient starts the study for a final check-up. It is planned that about 80 people with Adenovirus Conjunctivitis will be enrolled in this study between 8-12 sites across the United States. The patient will be assigned to either Zirgan or Genteal gel by chance which is similar to flipping a coin. The study groups will be assigned in a 1:1 ratio. Neither the patient nor the study doctor or study staff will be able to pick which study group The patient is in. The patient will not know and the study doctor or study staff will not know which study group the patient is in. The study doctor or study staff can find out if it is necessary to know for your health. If this happens, the study doctor or study staff may not be able to tell the patient which study group the patient was in until everyone finishes the study.
