To conclude on the bioequivalence of Aterixen 100 mg tablets (Valenta Pharm JSC, Russia) and Aterixen 100 mg film-coated tablets (Valenta Pharm JSC, Russia) administered in single doses under fasting conditions in healthy volunteers.

In this study 30 healthy adult participants will receive a single dose of an Ebola vaccine. Blood samples, fine needle aspirates, core biopsies, and bone marrow aspirates will be collected prior to and following vaccination to assess immune responses in the blood, lymph nodes, and bone marrow over multiple time points.

The goal of this randomized clinical trial is to investigate the optimal supportive treatment of bronchiolitis in infants from 0-12 months of age. The main question[s] it aims to answer are: To investigate whether isotonic saline should be used as supportive treatment for children with bronchiolitis, and if so, identify the optimal route of administration. The primary outcome is duration of hospitalization. To investigate the current epidemiology of the viral pathogens causing bronchitis in children in Denmark, and to assess whether children infected with specific pathogens might benefit from treatment with isotonic saline. The children are randomized after inclusion through computer randomization to one of the 3 arms in the study: Nebulized isotonic saline Nasal irrigation with isotonic saline No treatment with saline The investigators will compare treatment with saline (both methods) with no treatment, and the investigators will also compare the two methods of delivery of saline (nebulized vs. nasal irrigation).

The purpose of this study is to evaluate pharmacokinetics, safety, tolerability, antiviral activity, and impact on the clinical course of Respiratory Syncytial Virus (RSV) infection after multiple oral doses of JNJ-53718678 at different doses and/or dosing regimens in infants (greater than [>] 1 month to less than or equal to [<=] 24 months of age) who are hospitalized with RSV infection.

The purpose of this study is to characterize the Pharmacokinetic and to confirm the popPK model derived from healthy volunteers in hospitalized adults who are infected with respiratory syncytial virus (RSV) and to determine in adults who are hospitalized with respiratory syncytial virus (RSV) infection the dose response relationship of multiple regimens of lumicitabine on antiviral activity based on nasal RSV shedding using quantitative real-time reverse transcriptase-polymerase chain reaction (qRT-PCR) assay.

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 evaluate the effect of JNJ-53718678 on the development of respiratory syncytial virus (RSV) lower respiratory tract infection (LRTIs) in adult hematopoietic stem cell transplant (HSCT) recipients with RSV upper RTI.

The purpose of this study is to evaluate the antiviral activity, clinical outcomes, safety, tolerability, and pharmacokinetic/pharmacodynamic relationships of different oral dose levels of JNJ-53718678 in children greater than or equal to 28 days and less than or equal to 3 years of age with respiratory syncytial virus (RSV) disease (hospitalized participants [Cohort 1] or outpatients [Cohort 2]).

Coronavirus disease 2019 (COVID-19) is caused by the newly discovered coronavirus, SARS-CoV-2. The median time from onset of symptoms of COVID-19 to development of acute respiratory distress syndrome (ARDS) has been reported as short as 9 days. No effective prophylactic or post-exposure therapy is currently available. According to data from the Danish Health Authority (www.sst.dk/corona), as of March 21st, 2020, there were 1326 patients infected with the disease in Denmark, more than 250 are admitted to a hospital, and >50 of them have required intensive care. Nearly 350.000 cases and 15.000 deaths have been reported globally. These numbers are likely to markedly increase during the coming weeks, challenging the capacity of health systems worldwide. In patients infected with SARS-CoV-2, it has been described that disease severity and outcomes are related to the characteristics of the immune response. Interleukin (IL)-6 and other components of the inflammatory cascade contribute to host defense against infections. However, exaggerated synthesis of IL-6 can lead to an acute severe systemic inflammatory response known as 'cytokine storm'. In the pathogenesis of SARS-CoV-2 pneumonia, a study found that a cytokine storm involving a considerable release of proinflammatory cytokines occurred, including IL-6, IL-12, and tumor necrosis factor α (TNF-α). Studies on the Middle East respiratory syndrome caused by another coronavirus (MERS-CoV), indicate that cytokine genes of IL-6, IL-1β, and IL-8 can be markedly upregulated. Similarly, patients with SARS-CoV-2 pneumonia admitted to an intensive care unit had higher plasma levels of cytokines including IL-6, IL-2, IL-7, IL-10, granulocyte-colony stimulating factor (G-CSF), interferon-γ-inducible protein (IP10), monocyte chemoattractant protein (MCP1), macrophage inflammatory protein 1 alpha (MIP1A), and TNF-α. These findings indicate that the magnitude and characteristics of the cytokine response is related to the severity and prognosis of patients with SARS-CoV-2 pneumonia. It has been suggested that IL-6 blockade may constitute a novel therapeutic strategy for other types of cytokine storm, such as the systemic inflammatory response syndrome including sepsis, macrophage activation syndrome and hemophagocytic lymphohistiocytosis. Remarkable beneficial effects of IL-6 blockade therapy using a IL-6 receptor inhibitor has been described in patients with severe SARS-CoV-2 pneumonia in a retrospective case series from China. Currently, there are two available drugs based on human monoclonal antibodies against IL-6 receptor, tocilizumab (RoActemra, Roche) and sarilumab (Kevzara, Sanofi). IL-6 receptor inhibitors are currently licensed for several autoimmune disorders and are considered well tolerated and safe in general. The most common side effects reported are upper respiratory tract infections, headache, hypertension, and abnormal liver function tests. The most serious side effects are serious infections, complications of diverticulitis, and hypersensitivity reactions. it is hypothesized that IL-6 might play a key role in the cytokine storm associated with serious adverse outcomes in patients infected with SARS-CoV-2 pneumonia, and that blockade of IL-6 would be suitable therapeutic target for these patients. The study will investigate the effect of different types of IL-6 inhibition versus no adjuvant treatment compared to standard of care in patients with severe SARS-CoV-2 pneumonia. Primary objective: To compare the effect of either one of three IL-6 inhibitor administrations, relative to the standard of care, on time to independence from supplementary oxygen therapy, measured in days from baseline to day 28, in patients with severe SARS-CoV-2 pneumonia.

The purpose of this study is to evaluate the safety, infectivity, and immunogenicity of two doses of the HPIV3/ΔHNF/EbovZ GP vaccine candidate when administered intranasally in healthy adults.
