Active clinical trials for "Adenoviridae Infections"

This is a phase 1 study, in healthy volunteers who have previously been immunized with bacilli Calmette Guerin (BCG), to evaluate the safety and immune responses that develop in the blood and lungs following the administration by aerosol of a new experimental adenovirus-based vaccine for tuberculosis (TB), Ad5Ag85A.

The purpose of this study is to test the recombinant vaccine for safety and immunogenicity in healthy adults volunteers. Single dose, intranasally administered vaccine using an adenovirus-recombinant vector has provided a safe route for inducing protection in animals against pandemic influenza in preclinical studies. The vaccine is non-replicating, tissue culture based and designed for intranasal delivery.

This is a multicenter, US-only, phase 1, open-label, dose escalation, non-randomized study of the safety, tolerability, and immunogenicity of investigational ChAd and SAM SARS-CoV-2 vaccines in healthy adult subjects. Homologous and heterologous prime-boost vaccination schedules (Stage 1), as well as boost(s) after receipt of COVID-19 EUA/licensed vaccines (Stage 2) will be examined. Subjects' willingness to receive ChAd vaccines will be assessed and documented at the time of informed consent and considered to determine group assignments. This phase 1 study will enroll 17 Stage 1 and up to 118 Stage 2 subjects. Eligible subjects will be enrolled in different groups based on their age (18-60 years old and >60 years old) and their EUA/licensed COVID-19 vaccination status. A sentinel approach with 72-hour (Stage 1, and Stage 2, Groups 5, 6, 8-10, 12, 13-15) or 7-day observation times (Groups 7 and 11) will be used, before recruiting the remainder of each dose escalation group. Decisions about dose escalation will be determined by the SSC with consultation with the DSMB as needed after all subjects in each group have been observed through Day 8 post first study vaccination. All subjects will be followed through 12 months after their last study vaccination. Vaccinated subjects will be carefully monitored for exposure and infection to SARS-CoV-2 throughout the study. Escalation to the highest dose (10 µg) of SAM-S-TCE in younger subjects will proceed only following safety assessments of the 10 µg dose in older subjects for a period of 28 days post-vaccination. In addition, the dosage of SAM-S-TCE given as a double boost to subjects previously vaccinated with the Johnson & Johnson/Janssen Ad26 COVID-19 EUA/licensed vaccine in Groups 8A, 8B, and 12A, 12B will be determined based on the dose escalation reactogenicity and immunogenicity results in Groups 5-7 and 9-11, respectively. After protocol version 9.0 was implemented, it was decided not to enroll subjects into Groups 7 and 8 because of competing priorities and predicted difficulties enrolling into these two groups. The primary objectives of this study are 1) To assess the safety and tolerability of different doses of ChAd-S or ChAd-S-TCE, and SAM-S or SAM-S-TCE when administered as prime-boost in healthy naïve adult subjects, 2) To assess the safety and tolerability of different doses of ChAd-S or ChAd-S-TCE, and SAM-S or SAM-S-TCE when administered as first or second boost in healthy adult subjects previously vaccinated with an mRNA or adenoviral-vectored COVID-19 EUA/licensed vaccine.

Background: - Ebola virus causes an infection known as Ebola virus disease (EVD). This it is generally a severe disease which can also lead to death. The 2014 outbreak of EVD in West Africa is the largest ever. Researchers want to develop a vaccine to prevent Ebola infection. It is impossible for someone to get an Ebola infection from this vaccine. Objectives: - To see if an Ebola vaccine is safe and to study immune responses to it. Eligibility: - Healthy adults ages 18-65. Design: Participants will be screened through a separate protocol. Participants will receive the vaccine injection by needle and syringe into an upper arm muscle. - Participants will stay at the clinic for 3 hours after the injection. About 2 days later, participants must speak with clinic staff about how they are doing. Every day for 7 days after the injection, participants will record their temperature and symptoms and look at the injection site. They will get a thermometer and a ruler to measure any redness or swelling. They will report any side effects. In the first 2 months in the study, participants will have at least 6 clinic visits and 1 phone call. They will have at least 3 other visits over the next 9 months. At each visit, participants will be checked for health changes or problems since their last visit. They will be asked how they feel and if they have taken any medicine. Blood will be drawn at most visits. Urine samples may be collected.

The purpose of this study is to intensively characterize the immune response, particularly the T-cell response, to a three-dose regimen of an adenovirus-based HIV-1 vaccine in HIV-uninfected adults.

The 2019 novel-coronavirus (2019-nCov) is the cause of a cluster of unexplained pneumonia that started in Hubei province in China. It has manifest into a global health crisis with escalating confirmed cases and spread across many countries. In view of the fact that there is currently no effective antiviral therapy, the prevention or treatment of diseases caused by COVID-19 can be tough for current treatment. This study is a phase I clinical trial of booster vaccination of adenovirus type-5 vectored COVID-19 vaccine 6 months after prime vaccination. The investigators intent to evaluate the safety and immunogenicity of booster vaccination of adenovirus type-5 vectored COVID-19 vaccine in healthy adults aged aged 18-60 years.

Invasive infections with CMV and Adenovirus, not responding to virostatic treatment are treated with virusspecific donor derived or autologous virusspecific T-cells.

Patients enrolled on this study will have received a stem cell transplant. 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 if the immune system is weakened (like after a transplant), they can cause life-threatening infections. Adenovirus (AdV) is a virus that just causes symptoms of a common cold normally, but which can cause serious life-threatening infections in patients who have weak immune systems. It usually affects the lungs and can cause a very serious pneumonia, but it can also affect the gut, the liver, the pancreas and the eyes. Investigators want to see if they can use a kind of white blood cell called T cells to treat adenovirus infections that occur after a transplant. Investigators have observed in other studies that treatment with 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 when a patient already has an infection. Investigators have now generated AdV-specific T cells from the blood of healthy donors and created a bank of these cells. Investigators have previously successfully used frozen virus-specific T cell lines generated from healthy donors to treat virus infections after bone marrow transplant, and have now improved the production method and customized the bank of lines to specifically and exclusively target AdV. In this study, investigators want to find out if the banked AdV-specific T cells derived from healthy donors are safe and can help to treat adenoviral infection. The AdV-specific T cells (Viralym-A) are an investigational product not approved by the Food and Drug Administration (FDA). Funding source - FDA OOPD

Epstein Barr Virus (EBV) or Cytomegalovirus (CMV) infection results in significant morbidity and mortality in hematopoietic stem cell transplantation (HSCT) patients. HSCT patients often face opportunistic infections due to the immunosuppressive state during transplantation. Antimicrobial drugs are usually used for prophylactic purposes and for treatment after early detectable infections. Unfortunately, some patients develop resistance to such drug treatment. In addition to HSCT patient, immune compromised patient may also be victim to opportunistic infections. Many infections can be effectively managed by functional immune recovery. In this study, the safety and efficacy of microbial-specific cytotoxic T lymphocytes (CTLs) will be investigated.

The purpose of this study is to study the use of ganciclovir gel 0.3% for treatment of conjunctivitis caused by adenovirus.
