Active clinical trials for "Epstein-Barr Virus Infections"

The aim of this study is to assess the occurrence of antibodies cross-reacting with autoantigens that have been detected in the context of SLE in patients with primary EBV infection over time compared to a control group. It is to establish a biobank of patients with primary EBV infection allowing to longitudinally analyze the immune response and its accompanying inflammatory processes with focus on the occurrence of antibodies cross-reacting with autoantigens associated with SLE and other autoimmune diseases. Substudies will analyze characteristics of primary EBV infection patients treated with antibiotics in comparison to patients treated without antibiotics and outcomes of these treatment regimens (occurrence of acute complications such as peritonsillar abscess (PTA) or need for tonsillectomy, frequency of fatigue or symptoms associated with chronic fatigue syndrome). Procalcitonin (PCT) concentrations in primary EBV infection compared to control patients with similar symptoms and its association with disease severity and local complications. the occurrence of fatigue and symptoms associated with chronic fatigue syndrome 6 and 12 months after primary EBV infection.

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.

This is a multicenter, open-label, single-arm Phase 1B/2 study to assess the safety and efficacy of tabelecleucel in combination with pembrolizumab for the treatment of subjects with platinum-pretreated, recurrent/metastatic Epstein-Barr Virus-associated Nasopharyngeal Carcinoma (EBV+ NPC).

The purpose of this study is to determine if treatment with HQK-1004 and valganciclovir will result in complete or partial responses in patients with EBV-positive lymphoid malignancies or lymphoproliferative disorders.

COPD is a major public health problem and will shortly become the third most common cause of global mortality. There are currently no treatments that can meaningfully alter the progression of COPD or the time to death. Consequently novel therapeutic strategies for COPD are urgently required. This will be a randomised, double-blind, placebo-controlled, trial of Epstein-Barr virus suppression in COPD. Participants will be randomised to receive valaciclovir 1 gram three times daily for 8 weeks or matching placebo. The study will measure EBV suppression using quantitative PCR. Secondary outcomes will include Lung function quality of life and drug tolerability. The exploratory analysis will evaluate biomarkers of airway inflammation within the sputum and blood.

The investigators intend to utilize reduced intensity conditioning and allogeneic stem cell transplant from EBV positive HLA matched sibling or unrelated adult donor combined with post AlloSCT allogeneic donor derived LMP specific cytotoxic T-lymphocyte (CTL) infusions in EBV positive patients with poor risk Hodgkin Lymphoma. One of three reduced intensity conditioning regimens predetermined at each institutional center of the Childhood, Adolescent and Young Adult Lymphoma Cell Therapy Consortium (LCTC) will be utilized for related or matched unrelated adult donor allogeneic transplant followed by donor LMP specific CTL infusion for three doses post AlloSCT. The investigators hypothesize that the addition of donor derived LMP specific CTLs will be safe and feasible.

This is a single-arm, multi-center, open-label, phase II trial to examine the efficacy of pembrolizumab for prolonging the one-year disease free survival in nasopharyngeal carcinoma patients with solely detectable EBV DNA after curative chemoradiation. Sixty-three patients will be enrolled in the trial.

By combining a variety of agents that potentiate Zidovudine (ZDV), the investigators hope to induce remission in this generally fatal disease. Most therapies for aggressive B cell lymphomas are based upon intensive chemotherapeutic regimens, expensive modalities (bone marrow transplant, Rituximab), or experimental approaches (gene therapy, cytotoxic T cell infusion) that are difficult to implement in heavily pre-treated patients. Therapy for relapsed aggressive B cell lymphomas is very poor. Even curable lymphomas such as Burkitt Lymphoma (BL) and Hodgkin lymphoma are extremely difficult to treat in relapse and/or after stem cell transplant failure. The investigators propose a novel therapeutic approach that exploits the presence of Epstein-Barr virus (EBV) in lymphomas; antiviral mediated suppression of NF-kB and disruption of viral latency.

VK-2019-001 is a 1/2a trial of the oral EBNA-1 targeting agent VK-2019 in patients with EBV-positive recurrent or metastatic NPC to determine the Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D), as well as to evaluate the PK profile of VK-2019.

This study will enroll patients with non-metastatic nasopharyngeal carcinoma (NPC) that have residual Epstein-Barr virus (EBV) DNA after curative radiotherapy or chemoradiotherapy. The purpose is to evaluate the survival in these patients treated with apatinib (YN968D1), an inhibitor of vascular endothelial growth factor receptor (phase IIa) and to compare the survival in these patients treated with apatinib versus placebo (phase IIb).
