Active clinical trials for "Virus Diseases"

This study is designed to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single and multiple ascending doses in healthy volunteers (HV) and participants diagnosed with chronic hepatitis B (CHB).

Phase 1, single-center, placebo-controlled, single-blind, first-in-human, single ascending dose (SAD) study followed by a multiple-dose cohort in healthy male and female subjects.

The purpose of this study is to evaluate the safety and pharmacokinetics of UV-4B oral solution when administered to healthy subjects three times a day (TID) for 7 days.

The purpose of this study is to assess the safety and efficacy of combination treatment with VX-222 and telaprevir administered for 12 weeks with and without peginterferon-alfa-2a and/or ribavirin. The subjects enrolled in this study are chronically infected with hepatitis C virus (HCV) genotype 1 and will not have previously received treatment for their HCV infection. This study will include an Investigational Phase and Extension Phase. These phases will contain a Treatment Period and a Follow-up Period. All subjects will be enrolled in the Investigational Phase of this study. Subjects who fail treatment during the Investigational Phase will have the option to enter the Extension Phase at which point they will be eligible to receive peginterferon alfa-2a and ribavirin for a total of 48 weeks. Based on an evaluation of on-treatment safety, pharmacokinetic and antiviral data from patients in each arm of the trial, Vertex may elect to enroll up to two additional treatment arms (Treatment Arm E and Treatment Arm F) that will evaluate telaprevir/VX-222-based combination therapy. The components of the treatment regimens of these arms will be selected based on clinical data that emerges from the four initially-studied regimens. If enacted, up to 25 patients are expected to enroll in each additional treatment arm. If Treatment Arm E or Treatment Arm F is discontinued subjects meeting certain criteria will have the option to enter a telaprevir-containing Rollover Phase. Subjects who do not meet the eligibility criteria to enter the Rollover Phase may elect to enter the Extension Phase.

This study will reach out to patients who have undergone diagnostic testing for the following respiratory illnesses from January 1st, 2018 to July 9th, 2023: COVID-19, Influenza, Rhinovirus, and Respiratory Syncytial Virus. This study aims to develop a forecasting model to predict infection onset prior to symptom onset using wearable device data and known symptom onset and test dates.

This study is a prospective accuracy observational study to evaluate the performance of the Highplex System SARS-Cov-2, Influenza and RSV 8-well in vitro diagnostic medical device panel and generate performance data. The precision of results will be evaluated in concordance with the comparator predicate device panel BioFire Respiratory Panel 2.1 (RP2.1).

This community-based mixed methods study intends to identify, explore, and assess the determinants of community preparedness for outbreak situations, including acceptance for Ebola vaccines.

Study to assess the efficacy and safety of XC8, film-coated tablets, 10 mg in comparison with placebo in patients with dry non-productive cough against acute respiratory infection.

The study is planned to evaluate the therapeutic efficacy and safety of Ingavirin®, syrup, 30 mg/5 ml, in the treatment of influenza or other acute respiratory infections in children from 6 months to 2 years compared with placebo.

PIDD represent an expanding group of genetic disorders that compromise immunity against bacteria, viruses, and fungi. The most severe forms of PIDD cause profound susceptibility to opportunistic infections due to impaired or absent T-cell immunity. These diseases can be rapidly fatal unless treated via hematopoietic stem cell transplantation (HSCT). Chronic viral illnesses are a common presenting feature of many of these disorders, and studies have shown that survival of HSCT is profoundly impacted by the patient's pre-transplant disease status. Primary infections with viruses such as cytomegalovirus (CMV) and Epstein-Barr virus (EBV) are common, and respiratory viruses such as adenovirus also frequently cause infection. In patients with severe combined immunodeficiency (SCID), a prior study identified these viruses as the most common causes of mortality in the immediate period following HSCT. Though some forms of PIDD are amenable to HSCT without requiring conditioning chemotherapy, many forms require a variable degree of pre-conditioning to ensure that stable engraftment of the donor cells is achieved. The administration of cytotoxic chemotherapy used in the conditioning regimens can however increase the risk for regimen related toxicity and for some patients (especially those with active viral infections) this risk is particularly high, leading to high treatment related mortality rates. For these reasons, many such patients are not even considered candidates for HSCT or are delayed getting to HSCT and ultimately succumb to infection before they can receive the transplant. The primary objective of this study is to determine the safety of administering third-party multivirus-specific cytotoxic T lymphocytes (mCTL) from adult CMV seropositive donors to treat refractory viral infections in patients with primary immunodeficiency disorders (PIDD) prior to hematopoietic stem cell transplantation (HSCT).
