Filter by: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.
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.
To depict the incidence, outcomes and standards of care (SoC) of adenovirus (AdV) infections and associated practice patterns in allogeneic hematopoietic cell transplant recipients. It is expected that participating centers will be in the United Kingdom, France, Spain, Germany, and Italy.
Proposal of a "rapid typing" technique by a new real-time PCR method, simpler, faster and cheaper than nucleotide sequencing (reference method) for rapid typing in Adenovirus infections.
Fourteen patients will be included for infusion of adenovirus-specific T-cells generated by a clinical grade IFN-γ based immunomagnetic isolation from a leukapheresis from their original donor or a haploidentical donor, in case of Umbilical cord blood transplantation, in the event of refractory ADV infection or disease.
Glioblastoma (GBM) and gliosarcoma (GS) are the most common and aggressive forms of malignant brain tumor in adults and can be resistant to conventional therapies. The purpose of this Phase II study is to evaluate how well a recurrent glioblastoma or gliosarcoma tumor responds to one injection of DNX-2401, a genetically modified oncolytic adenovirus, when delivered directly into the tumor followed by the administration of intravenous pembrolizumab (an immune checkpoint inhibitor) given every 3 weeks for up to 2 years or until disease progression.

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.
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.
In this study, investigators are trying to see if infusion of "m-CTLs" will prevent or treat cytomegalovirus (CMV), Epstein Barr Virus (EBV) and adenovirus (AdV) reactivation or infection after cord blood transplant. Patients with blood cell cancer, other blood disease or a genetic disease may receive a cord blood transplant (UCBT) from an unrelated donor. After receiving a cord blood transplant, they are at risk of infections until a new immune system to fight infections grows from the cord blood cells. In this study, investigators are trying to give special cells from the cord blood called T cells. These cells will try to fight viruses that can cause infection. Investigators will test to see if blood cells from donor that have been grown in a special way, can prevent patients from getting an infection. EBV, AdV and CMV are viruses that can cause serious life-threatening infections in patients who have weak immune systems after transplant. T lymphocytes can kill viral cells but normally there are not enough of them to kill all the virus infected cells after transplant. Some researcher have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person during a viral infection after a bone marrow transplant. Some of these studies have shown a positive therapeutic effect in patients receiving the CTLs (specially trained T cells) after a viral infection in the post-transplant period. In this study we are trying to prevent or treat viral infections by given the CTLs soon after getting the umbilical cord blood transplant. With this study, investigators want to see if they can use a kind of white blood cell called T cells to prevent or treat AdV, EBV and CMV infection. Investigators will grow these T cells from the cord blood before transplant. These cells have been trained to attack adenovirus/EBV/CMV- infected cells and are called multivirus-specific cytotoxic (killer) T-cells or "m-CTL." Investigators would plan to give patients one dose of m-CTL any time from 30 to 364 days after your transplant. They 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 investigators make them from cord blood.
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.
