Filter by:This study is a prospective, single arm, multi-center phase II clinical trial designed to evaluate the efficacy and safety of perioperative SOX combined with toripalimab in participants with Epstein-Barr Virus-associated locally advanced gastric or esophagogastric junction adenocarcinoma.
This research study is being performed to find out if Truvada (tenofovir/emtricitabine), an antiviral drug with activity against the Epstein Barr virus (EBV), can reduce EBV levels in saliva and blood in people with multiple sclerosis (MS). A second goal is to find out if Truvada (tenofovir/ emtricitabine) is safe and tolerable in people with MS.
This research study is evaluating the combination of drugs, pembrolizumab with chimeric antigen receptor (CAR) T-cell therapy, as a possible treatment for primary mediastinal B-cell lymphoma that has recurred after prior treatment. The names of the study drugs involved in this study are: - Pembrolizumab Standard treatment will include: - CAR T-cell therapy (either axicabtagene-ciloleucel or lisocabtagene maraleucel) - Cyclophosphamide - Fludarabine
This prospective case-control study aims to evaluate the immune function and find PD-1 antibody efficacy predictors on Chronic Active Epstein-Barr Virus Infection and Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis by detecting lymphocyte subsets proportions in peripheral blood mononuclear cells and the positive proportion of PD-1, PD-L1 and other indicators in each lymphocyte subsets in healthy people and patients using flow cytometry before and after the initial PD-1 therapy.
The purpose of this study is to evaluate the safety and reactogenicity of mRNA-1195 in healthy adults (18 to 55 years of age).
The clinical course of RRMS patients is variable. Among RIS-Consortium international cohorts, one third of RIS patients progressed to MS at 5 years and 52.2% at 10 years. Biomarkers predictive of MS conversion are key elements to organize personalized medical care, for both follow-up and treatment strategies. EBV seems to be an interesting candidate regarding its involvement MS pathophysiology. It can be easily assess in blood sample in contrast to others prognostic biomarkers validated in RIS : oligoclonal bands and NfL levels in cerebrospinal fluid and serum. In RIS, treatment targeting EBV could significantly modify the course of the disease. The investigators aim to make the fisrt description of the EBV epidemiology (immunoglobulin (Ig)M and IgG anti-viral capsid antigen (VCA), IgG anti Epstein-Barr nuclear antigen (EBNA)) among RIS patients and to investigate a correlation between the different antibodies' titers (IgM VCA, IgG VCA, IgG EBNA) and the course of the disease (clinical conversion or evidence of disease activity (EDA)).
Chronic fatigue syndrome (syn. myalgic encephalomyelitis or ME/CFS) is a relatively common, but pathogenetically still insufficiently understood, complex, severe, chronic disease. It has been classified by the WHO as a neurological disorder (ICD-10 G93.3). The leading symptoms are pathological exhaustion (fatigue) and prolonged, inadequate deterioration of condition after exertion (syn. post-exertional malaise or PEM). In addition, pain, sleep disturbances, flu-like symptoms, and cognitive, autonomic, and neuroendocrine symptoms are typically found. In the majority of patients*, the trigger is a viral disease, including infectious mononucleosis caused by Epstein-Barr virus (EBV), which is particularly common in young patients, but also influenza or coronavirus disease 2019 (Covid-19) at any age. Causative factors are discussed to be autoimmune mechanisms as well as a genetic predisposition. The general activity level and quality of life of patients are usually significantly reduced due to the disease. A large proportion of those affected are confined to a wheelchair, home or bed. ME/CFS is one of the most common reasons for long absences from school due to illness. Because no reliable biomarkers are available, ME/CFS is a diagnosis of exclusion. The diagnosis is made using internationally established clinical criteria and after careful differential diagnosis. To date, no causal, but only symptom-oriented, non-standard treatment approaches are found. With appropriate care, the prognosis in childhood and adolescence is better than in adults. Long-term recovery is possible in two-thirds of young patients, whereas less than one-third of adult patients can expect recovery. In Germany, there are currently two special outpatient clinics for patients with ME/CFS, one for adult patients* at the Charité Fatigue Centrum in Berlin, headed by Prof. Scheibenbogen, and one for children, adolescents and young adults up to 25 years of age at the ME/CFS focus of the Children's Polyclinic of the MRI of the TUM in Munich, headed by Prof. Behrends. A joint data collection of these ME/CFS centers has not been established. The proposed ME/CFS registry study (MECFS-R) is intended to initially pool medical data from specialized routine care on a bicenter basis and, after recruitment of additional German centers, on a multicenter, longitudinal, and web-based basis, as extensive as possible, and to make this data available for research. Following the example of already well-established European registry studies (e.g., the ESID registry of the European Society for Immunodeficiencies), digital data acquisition should take place in a tiered approach according to cost-benefit analysis. Medical institutions can decide, based on capacity, whether a clearly defined core data set (level 1) or more complex data sets (level 2 or 3) should be digitally captured. The digital implementation is to be carried out in collaboration with the Munich-based IT company Bitcare, whose database concepts have proven successful in the context of the Transplantation Cohort (Tx Cohort) of the German Center for Infection Research (DZIF) or the Covid-19 study of the MRI of TUM (COMRI) and with whom the team at the MRI of TUM has been working successfully for many years. The aim of the MECFS-R is to accurately describe the clinical picture and its course in Germany clinically and epidemiologically as well as to derive epidemiological or medical risk factors, if applicable, and to define subcohorts for future treatment approaches.
The efficacy and safety of L-DEP (PEG-aspargase, liposomal doxorubicin, etoposide, and methylprednisolone) regimen combined with PD-1 Antibody an induction therapy for Epstein-Barr virus (EBV)-positive lymphoma-associated hemophagocytic lymphohistiocytosis.
Background: Epstein-Barr virus (EBV) causes most cases of infectious mononucleosis (mono). Mono can cause fatigue that lasts more than 6 months, and some people can have severe complications. EBV infection may also contribute to some cancers and autoimmune diseases. Currently, there are no approved therapies or vaccines for EBV infection. Objective: To test a vaccine against EBV. Eligibility: Healthy people aged 18 to 25 years. Design: Participants will be screened in 2 parts. They will have a blood test. If that test shows they have never had an EBV infection, they will have a second clinic visit. They will have a physical exam, with blood and urine tests. A cotton swab will be rubbed on their gums to collect saliva. Participants will receive 2 injections into a shoulder muscle. Some will receive the EBV vaccine. Others will receive a placebo; this contains harmless salt water with no vaccine. Participants will not know which one they are getting. The 2 injections will be 30 days apart. Participants will be asked to record any side effects or symptoms they have between visits. They can do this on paper or online. Participants will return for a follow-up visit 60 days after the first injection. They will have follow-up visits by phone or telehealth after 5 and 8 months. They will return for a physical exam after 13 months. They may come back for an optional physical exam after 2 years. Participants will come to the clinic if they become ill with an EBV infection during the study.
The transformation process of nasopharyngeal carcinoma is complex, so it is particularly important to explore the relationship between various disease states on its clinical pathway. Therefore, we carried out this study to explore the changes of plasma and urine metabolites at different stages during the occurrence and development of nasopharyngeal carcinoma.
