Active clinical trials for "Virus Diseases"

A new paediatric formulation (oral liquid) has been developed for flexible and accurate dosing of valacyclovir in children. To establish the bioavailability of this new formulation, healthy volunteers will be exposed to the new formulation and to valacyclovir tablets. The concentration of valacyclovir in their blood after exposure to the oral liquid will be measured and compared to the tablet.

Rectal and genital sampling in HIV prevention trials permits assessments at the site of HIV entry. Yet the safety and acceptability of circumcision and sigmoidoscopy (and associated abstinence recommendations) are unknown in uncircumcised men who have sex with men (MSM) at high risk of HIV infection. The purpose of this study is to evaluate the feasibility of methods for assessing baseline characteristics of the mucosa of MSM at risk of HIV infection in Lima, Peru.

The purpose of this long-term follow-up (LTFU) study is to evaluate the incidence of the clinical diagnosis of asthma and the frequency of wheezing in infants and children with respiratory syncytial virus (RSV) infection who were treated with (lumicitabine or placebo) and have completed their last planned study-related visit in a feeding Phase 2 study (64041575RSV2004).

This Phase 3 study is intended to assess the clinical lot-to-lot consistency in manufacturing by evaluating and comparing the immunogenicity of three consecutively manufactured lots of the Quadrivalent Virus-Like Particles (VLP) Influenza Vaccine, during the 2016-2017 influenza season, in healthy adults 18-49 years of age. A single dose of one of three consecutive lots of Quadrivalent VLP Influenza Vaccine (30 µg/strain) will be administered to 1,200 participants.

The study aimed for: Comparative evaluation of the safety of the drug Molnupiravir, capsules, 200 mg (JSC "Valenta Pharm", Russia), and Lagevrio, capsules, 200 mg (Merck Sharp & Dohme (UK) Limited, UK), based on the analysis of adverse events (AEs); Comparative assessment of pharmacokinetic parameters and bioequivalence of the drug Molnupiravir, capsules, 200 mg (Valenta Pharm JSC, Russia), and Lagevrio, capsules, 200 mg (Merck Sharp & Dohme (UK) Limited, UK), in healthy volunteers in fasted conditions.

The study is funded through the Office of the Global AIDS Coordinator (OGAC #KE-07-0044). The purpose of this study is two-fold. The first purpose is to see if routine monitoring of the level of HIV virus in the blood (viral load) every six months is superior to monitoring by standard clinical evaluations and or immune status (CD4 count) with intermittent viral load monitoring in adults receiving antiretroviral therapy (ART). The second purpose is to understand the cost implications and possible benefits of routine HIV viral load monitoring.

Primary, Secondary, and Exploratory Objective(s): Primary objective: To evaluate the effect of interventions on 1st dose uptake of HPV vaccine.

The study is expected to treat patients with mild and severe neo-coronary pneumonia through standard treatment regimens in combination with tetrandrine tablets, thereby reducing the clinical progress of some patients, improving prognosis, reducing the incidence of pulmonary fibrosis during rehabilitation, and improving patients' quality of life.

To investigate the mechanism, clinical outcome and therapeutic efficacy with favipiravir of Corona Virus Disease 2019 patients whose nucleic acids changed from negative to positive.

To evaluate the efficacy and safety of Anluohuaxian in blocking the progression of pulmonary fibrosis and improving lung function in patients with COVID-19.
