Active clinical trials for "Virus Diseases"

Rationale: Classical antiviral therapies target viral proteins and are consequently subject to resistance. To counteract this limitation, alternative strategies have been developed that target cellular factors. We hypothesized that such an approach could also be useful to identify broad-spectrum antivirals. The influenza A virus was used as a model for its viral diversity and because of the need to develop therapies against unpredictable viruses as recently underlined by the H1N1 pandemic. Gene-expression signature-based screening identified broadly effective influenza A antivirals. Midodrine showed great results in inhibiting viral growth and was the most suited to confirm its efficacy in vivo. The main objective of the study is to assess the efficacy of midodrine taken at usual recommended dose (7.5mg/day) versus no treatment on viral replication kinetics of virus Influenza A. Secondary objectives: evaluation of the number of patients with a normalized viral load 2, 3 5 and 7 days post-treatment; description of the anti-viral efficacy of midodrine defined as the delay to obtain a prolonged negativity of viral RNA; description of the tolerance of midodrine, evaluation of the clinical response to study treatment; evaluation of the dynamic of viral replication; analysis of the frequency of emergence of mutants and associated resistance. Methods: This is a multicenter, randomized, open-label study comparing patients aged 18 to 65 years infected by influenza A virus. Nasopharyngeal washing will be performed at day 0 (randomization), 2, 3, 5 to show the viral replication evolution. 161 patients will be randomized as follows : Arm 1 : Midodrine, 2.5 mg, 3 times a day Arm 2 : No treatment The recruitment is performed by general practitioners in the Lyon area.

Dose cohorts may be dosed with one of up to 4 possible total weekly doses (0.3 mg, 1 mg, 2 mg, 4 mg). Dose escalation or repetition will be governed by pre-specified safety and activity rules. Subjects will be confined on days 1-3 and/or days 8-10. Follow-up visits are required periodically through day 43. Subjects with sustained reductions in HbsAg will be requested to return for additional follow-up follow-up visits at 3 and 6 months post last dose. Study procedures involve blood draws for pharmacokinetic, pharmacodynamic, virologic, and safety assessments

This study is designed to compare the antiviral effect of ALS-008176 compared to a placebo control in the respiratory syncytial virus challenge model.

This randomized, double-blind, multiple-dose, placebo-controlled study will evaluate the safety, tolerability and efficacy of balapiravir in adult male patients with confirmed dengue virus infection whose symptoms began within the 48 hours preceding the first administration of balapiravir. Patients will be randomized to receive either balapiravir or placebo, orally twice daily for 5 days. Anticipated time on treatment as in-patient is 7 days, with an out-patient follow-up to week 12. Target sample size is <200

The purpose of this study was to evaluate the efficacy (and safety) of antiviral therapy in patients with chronic hepatitis C after liver transplantation. The only approved drugs for treatment of hepatitis C are pegylated interferon and ribavirin.

This study is a Phase 2/3, multicenter, double-blind, randomized, parallel-group, placebo-controlled, dose-finding trial of Serostim® (mammalian cell-derived recombinant human growth hormone, r-hGH) versus placebo in subjects with human immunodeficiency virus-associated adipose tissue redistribution syndrome (HARS). The primary study objective is to determine whether Serostim® treatment reduces adipose tissue maldistribution more effectively than placebo. The primary co-endpoints are derived from measures of visceral adipose tissue assessed by computerized tomography (CT) and the ratio of trunk; and limb fat assessed by dual-energy X-Ray absorptiometry (DXA) scans. Anthropometric measures, physical exams, quality of life assessments, serial photographs, and various laboratory measures will be used to address secondary objectives. These secondary objectives relate to the impact of Serostim® on Physician and subject assessments of change in body shape, health-related quality of life, attitude towards medication compliance, metabolic markers, fat redistribution, and safety. On Day 1, eligible subjects will be randomized in a 1:1:1 ratio to receive daily Serostim®, Serostim® and placebo given on alternate days, or daily placebo. Serostim® doses will be based on body weight, with a maximum dose of 4 milligram (mg). Therapy will continue for 12 weeks. Treatment will then be altered and the new treatment will be continued through Week 24. Interim Study Visits will be required at Weeks 2 and 4 (Treatment Period 1) and at Weeks 14 and 16 (Treatment Period 2). Subjects will be offered to be enrolled into a maintenance Protocol (Study 23056) at Week 24.

This is a research study to evaluate the safety, tolerability and anti-viral activity of GS-9669 in patients with Hepatitis C infection.

The purpose of this study is to test the safety and effectiveness of ribavirin, administered as an aerosol, in preventing progression of upper respiratory tract RSV infection to RSV pneumonia in bone marrow and peripheral blood transplant recipients.

To determine the safety, immunogenicity, biological activity, ad pharmacokinetics of sargramostim ( recombinant granulocyte-macrophage colony-stimulating factor; GM-CSF ) human granulocyte-macrophage colony-stimulating factor ( GM-CSF ), given by subcutaneous ( SC ) injection to patients with leukopenia in association with HIV infection.

This is a placebo-controlled, randomized, double-blind study to evaluate the pharmacokinetics of galidesivir following administration of single doses by IV infusion
