Active clinical trials for "Virus Diseases"

BK cytotoxic T cells (CTLs) manufactured with the Miltenyi CliniMACS Prodigy Cytokine Capture System will be safe and effective in decreasing specific viral load in children, adolescents and young adults (CAYA) with refractory BK infection post Allogeneic Hematopoietic Stem Cell Transplantation (AlloHSCT) or with primary immunodeficiencies (PID).

The study aims to demonstrate that antiviral therapy for patients with immune tolerance of CHB. On the basis of the original antiviral therapy of entecavir, further clarify the safety and effectiveness of entecavir combined with tenofovir amibufenamide.The investigators plan to enroll about 328 hepatitis B patients,. who are in the stage of immune tolerance. These participants will be devided into two groups randomly .Group A will receive the treatment of entecavir. Group B will be treated with entecavir and tenofovir amibufenamide. The participants in both groups will be followed up for 96 weeks. The primary endpoint is to compare the inhibition rate of HBV-DNA between two groups. The secondary endpoint includes: (1) Comparing the decrease of HBV DNA at 48 weeks between the two groups. (2) Comparing the HBeAg seroconversion rates at 48 weeks and 96 weeks between the two groups. (3) The changes of HBsAg at 48 weeks and 96 weeks between the two groups. (4) Comparing adverse side effects between the two groups.

The overall purpose of this study is to evaluate whether tecovirimat is an efficient and safe antiviral in the treatment of monkeypox in adults and adolescents (14 years old and older). The primary objective is to evaluate the clinical efficacy, as assessed by time to all visible lesion(s) resolution, of tecovirimat treatment + Standard of Care (SOC) compared to placebo + SOC for patients with monkeypox. The secondary objective is to evaluate the clinical efficacy, as assessed by mortality, hospitalization, complications, duration of symptoms and virological shedding, and the safety of tecovirimat treatment + SOC compared to placebo + SOC in patients with monkeypox.

HPV infection can lead to cancer, especially when precancerous lesions have developed and high-risk HPV is present. Glizigen is an oral and intravaginal treatment based on activated glycyrrhizinic acid that has shown potential benefit in patients with HPV. In order to improve the existing evidence, the present study consists of a randomized, double-blind, placebo-compared clinical trial to evaluate the efficacy of combined treatment with Glizigen Oral Solution and Glizigen Vaginal Gel for the resolution of biopsy-confirmed grade 1 cervical intraepithelial neoplasia (CIN-1) in patients with high-risk HPV.

This is a multicenter, randomized, controlled, open-label, Phase IIb study of HH-003 injection, HH-003 injection is a monoclonal antibody targeting Hepatitis B virus. This study aims to assess efficacy and safety in subjects with chronic hepatitis delta virus infection.

This is a first in human (FIH), multi-center, dose-finding, and dose-escalation Phase I clinical study of RO7565020 to investigate the safety and tolerability and to characterize the pharmacokinetics and pharmacodynamics following single and/or multiple doses of RO7565020 in healthy participants and/or virologically suppressed participants with chronic hepatitis B (CHB).

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.

Background: Recurrent respiratory papillomatosis (RRP) is a rare disease that causes wart-like growths in the airways. These growths come back when removed; some people may need 2 or more surgeries per year to keep their airways clear. Better treatments are needed. Objective: To see if a drug called bevacizumab can reduce the number of surgeries needed in people with RRP. Eligibility: People aged 18 and older with recurrent RRP; they must need surgery to remove the growths in their airways. Design: Participants will be screened. Their ability to breathe and speak will be evaluated. They will have an endoscopy: a flexible tube with a light and camera will be inserted into their nose and throat. They will have a test of their heart function and imaging scans of their chest. Participants will have surgery to remove the growths in their airways. Bevacizumab is given through a small tube placed in a vein in the arm. After the surgery, participants will receive 11 doses of this drug: every 3 weeks for 3 doses, and then every 6 weeks for 8 more doses. They will come to the clinic for each dose; each visit will be about 8 hours. Tissue samples of the growths will be collected after the second treatment; this will be done under general anesthesia. Participants may undergo apheresis: Blood will be drawn from a needle in an arm. The blood will pass through a machine that separates out the cells needed for the study. The remaining blood will be returned to the body through a second needle. Follow-up will continue for 1 year after the last treatment.

Recent advances have been made in prevention of the viral infection via vaccines but there is still need for effective treatment options for patients. Novel therapies need to be developed to further improve clinical outcomes. The biggest medical challenge in the response to COVID-19 is ARDS requiring hospitalization in an intensive care setting and ventilator dependence. Intravenously administered umbilical cord derived exosomes and stem cells have been reported in literature to alleviate pulmonary distress in such patients. The purpose of this study is to explore the safety and benefits of intravenous administration of WJPure and EVPure in the treatment of COVID-19 patients with moderate to severe ARDS. .

This study is a prospective single-arm clinical study, focusing on Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis and Chronic Active Epstein-Barr Virus Infection with only and mainly B lymphocytes of EBV infection, to evaluate the clinical efficacy of Rituximab in the treatment of EBV-HLH and CAEBV.
