The purpose of this study is to evaluate safety, tolerability and immunogenicity of mRNA-1345 in participants who have been previously vaccinated with either Arexvy or Abrysvo at least 12 months prior to enrollment, are medically stable and aged ≥60 years.
The primary objective is to determine the safety and feasibility of administering R-MVST cells to patients with refractory viral reactivation and/or symptomatic disease caused by Epstein Barr Virus (EBV), cytomegalovirus (CMV), adenovirus (ADV) or BK virus. R-MVST cells will be generated on-demand from the closest partially human leukocyte antigen (HLA)-matched (minimum haploidentical) healthy donors or from the original allo-transplant donor if available. The investigator will closely monitor the recipients for potential toxicities including graft-versus-host disease (GVHD) post-infusion. Secondary objectives are to determine the effect of R-MVST infusion on viral load, possible recovery of antiviral immunity post-infusion and for evidence of clinical responses and overall survival. Recipients will be monitored for secondary graft failure at day 28 post R-MVST infusion.
The primary purpose of this phase I/II study is to evaluate whether partially matched, ≥2/6 HLA-matched, viral specific T cells have efficacy against adenovirus, CMV, and EBV, in subjects who have previously received any type of allogeneic HCT or solid organ transplant (SOT), or have compromised immunity. Reconstitution of anti-viral immunity by donor-derived cytotoxic T lymphocytes has shown promise in preventing and treating infections with adenovirus, CMV, and EBV. However, the weeks taken to prepare patient-specific products, and cost associated with products that may not be used limits their value. In this trial, we will evaluate viral specific T cells generated by gamma capture technology. Eligible patients will include HCT and/or SOT recipients, and/or patients with compromised immunity who have adenovirus, CMV, or EBV infection or refractory viremia that is persistent despite standard therapy. Infusion of the cellular product will be assessed for safety and efficacy.
The participants are being asked to take part in this clinical trial, a type of research study, because the participants are scheduled to receive or have recently received a hematopoietic cell transplant (HCT) or a solid organ transplant (SOT). Primary Objective To determine if pre-transplant screening for respiratory viral load predicts RVI within 1- year post-transplant among survivors. Secondary Objectives: * To develop and validate a classifier based on pre-transplant immunological profile predictive of developing an acute respiratory viral infection (aRVI), with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors. * To develop and validate a classifier based on Day +100 post-transplant immunological profiles predictive of developing an acute respiratory viral infection (aRVI),with RSV/PIV3/HMPV/SARS-CoV-2 through one-year post-transplant among survivors .

This phase I trial tests the feasibility and safety of genetically modified cytotoxic T-lymphocytes in controlling infections caused by adenovirus (ADV), BK virus (BKV), cytomegalovirus (CMV), JC virus (JCV), or COVID-19 in immunocompromised patients with cancer. Viral infections are a leading cause of morbidity and mortality after hematopoietic stem cell transplantation, and therapeutic options for these infections are often complicated by associated toxicities. Genetically modified cytotoxic T-lymphocytes (CTLs) are designed to kill a specific virus that can cause infections. Depending on which virus a patient is infected with (ADV, BKV, CMV, JCV, or COVID-19), the CTLs will be designed to specifically attack that virus. Giving genetically modified CTLs may help to control the infection.
Background: Less toxic and more effective treatments are needed for cancers caused by viruses. These cancers include Hodgkin and non-Hodgkin lymphoma, hepatocellular carcinoma, head and neck cancer, nasopharyngeal carcinoma, gastric cancer, anal cancer, cervical cancer, vaginal cancer, vulvar cancer, penile cancer, Merkel cell carcinoma, Kaposi sarcoma, and leiomyosarcoma. Researchers want to see if a combination of drugs can help. Objective: To find a safe dose of pomalidomide plus nivolumab in people with cancers caused by viruses. Eligibility: Adults ages 18 or older who have cancers caused by Epstein Barr virus (EBV), human herpes virus 8/Kaposi sarcoma herpesvirus (HHV8/KSHV), human papilloma virus (HPV), hepatitis B or C virus (HBV/HCV), and Merkel cell polyomavirus (MCPyV) that have not responded to previous treatments or have relapsed, or in adults who do not want to have surgery because of disfigurement or other risks. Adults who have HIV with any CD4 T cell count are eligible. Design: Participants will be screened with blood and urine tests, scans, and heart tests. They will have a physical exam. Their ability to perform normal daily activities will be assessed. They may have a tumor biopsy. Treatment will be given in 28-day cycles. Participants will take pomalidomide as a tablet by mouth for 21 days of each cycle, for up to 24 cycles. They will get nivolumab by intravenous infusion once each cycle. They will take an aspirin each day until 30 days after their last dose of the study drugs. Participants will keep a pill diary. They will bring it to their study visit at the end of each cycle. At these visits, some screening tests will be repeated. Participants with Kaposi sarcoma will have pictures taken of their lesions. Participants will give blood and saliva samples for research. They may have optional anal and/or cervical swabs. They may have optional biopsies. Participants will have a follow-up visit 30 days after they stop taking the study drugs, then every month for 100 days. Some screening tests will be repeated. Then they may by contacted by phone every 3 months for 9 months, and then every 6 months thereafter....
The human immune system is designed to protect individuals from external sources of infection and internal cell mutation. It works effectively and efficiently until inflammation disturbs its functioning. Once compromised by inflammation, the immune system loses its capacity to recognize antigens and dependably defend the body against disease and illness. When COVID-19 invades humans, it causes an immune-storm (cytokine-storm) that can directly damage the organ(s), leading to death. The virus is an antigen - a trigger - but it is not the actual reason that causes organ failure and death; instead, it is the body's over immune reaction that is the cause. In attempting to protect the body, the immune system overreacts to the antigen, which includes the infected cells, which causes a cytokine-storm, and the subsequent and rapid shut down of the infected individual's organ(s)' structure, leaving the body without sufficient strength or time to fight back. When the medical herbs join the body, it can slow down the immune reaction. Medical herbs benefit the physical body; they protect the cells and organism structure and mediate the immune response, allowing the T cells to kill the virus (mutated or not) internally. Such success has been achieved by the All Natural Medicine Clinic during pre-clinical trials. This clinical study's goal is to demonstrate that the immune system can be rebuilt and retrained, using natural medicine (i.e., medical herbs), to kill the virus without causing the immune storm, and to explore the mechanism by which these medical herbs, which have been used for thousands of years for healing, achieve results.
Often when people with asthma get a virus caused by the common cold (rhinovirus), they also experience an increase or worsening of their asthma symptoms. The purpose of this study is to see if the study medication dupilumab helps prevent those with mild to moderate asthma from having increased asthma symptoms, after being exposed to an experimental rhinovirus inoculation. This is a study about dupilumab which is a drug approved by the U.S. Food and Drug Administration (FDA) for treatment of moderate to severe asthma. Dupilumab is a medication that blocks pathways that cause asthmatic inflammation in the lungs, leading to symptoms and worsening lung function. During this study, subjects will be given either dupilumab or placebo and will subsequently be exposed to the the "common" cold virus (rhinovirus). The virus that the investigators are using has been safely used before in many studies like this involving thousands of volunteers, and the safe use of the virus in this research study has been reviewed by the FDA. The investigators will track asthma symptoms during the study with lung function tests, questionnaires, specimen collection, biomarkers, and physical exams. For data analysis the investigators will assess the samples collected to determine changes in the treatment groups. The investigators will also asses the symptom scores and deviations from baseline measures for lung function.
The purpose of this research study is to learn more about the use of viral specific T-lymphocytes (VSTs) to prevent or treat viral infections that may happen after allogeneic stem cell transplant. Allogeneic means the stem cells come from another person. VSTs are cells specially designed to fight viral infections that may happen after a stem cell transplant (SCT). Stem cell transplant reduces the body's ability to fight infections. Viral infections are a common problem after transplant and can cause significant complications. Moreover, treatment of viral infections is expensive and time consuming, with families often administering prolonged treatments with intravenous anti-viral medications, or patients requiring prolonged admissions to the hospital. The medicines can also have side effects like damage to the kidneys or reduction in the blood counts, so in this study the investigators are trying to find a better way to treat these infections.
