Active clinical trials for "Virus Diseases"

In Chile, sexually transmitted infections (STI)s, including HIV / AIDS, are the main causes of morbidity in adolescents and young adults. The surveillance bulletin of the Institute of Public Health revealed an increase in cases of gonorrhea, over 200% in the last five years. HIV cases increased between 34% and 47% in this period as well. Unsafe sexual behaviors are among the most important risk factors for sexually transmitted infections (STI); it has been shown that educational / behavioral interventions can achieve success in behavioral changes, especially in young people. Some studies have evaluated the effectiveness of behavioral interventions to prevent sexual risk behavior of HIV and STIs with encouraging results. On the other hand, information and communication technologies (ICT) have been used in the prevention of STIs, HIV / AIDS. There is a considerable increase in the use of meta-universes or three-dimensional virtual worlds for educational purposes since 2006. No studies have yet been found that demonstrate the effectiveness of educational interventions carried out in meta-universes for the prevention of STIs in Chile. This study aims to demonstrate the effectiveness of a psychoeducational intervention through the use of meta-universes, on self-efficacy in the use of condoms and safe sexual behavior, in university students. An open randomized, controlled trial will be conducted. Dependent variables will be measured before the intervention and 15 days after the end of the intervention in the experimental group in both groups. Students from first year to fourth year of different careers (except Nursing), currently in the Universidad Autonoma de Chile will be included after their informed consent. The psychoeducational intervention consists of three sessions in which techniques based on three of the four sources of self-efficacy described are applied. The intervention will be carried out every 24 hours with four participants in four computers and 3D lenses available in the computer labs of the University. The dependent variables will be: 1) the self-efficacy in the use of male condom, measured with the Scale Condom self-efficacy scale of Brafford and Beck and 2) safe sexual behavior measured with Safe Sex Behavior Questionnaire scale of Dilorio, Lehr, Adame and Carlone. Both scales were culturally adapted to Chile.

The purpose of this study is to establish the dose-response relationship for antiviral activity of 3 dose levels of JNJ-73763989+nucleos(t)ide analog (NA) and to evaluate the efficacy of combination regimens of JNJ-73763989+NA (with and without JNJ-56136379) and of JNJ-56136379+NA.

The primary objectives of this study are to evaluate the antiviral efficacy, safety, and tolerability of sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) with or without ribavirin (RBV) for 12 weeks in adults with chronic hepatitis C virus (HCV) infection and decompensated cirrhosis.

The main purpose of this study is to evaluate the safety and tolerability of a combination treatment of AL-335, odalasvir (ODV), and simeprevir (SMV) for 8 weeks in Japanese participants with genotype 1 or 2 chronic hepatitis C virus (HCV) infection without cirrhosis and for 12 weeks in direct-acting antiviral (DAA)-naive Japanese participants with genotype 1 or 2 chronic HCV infection with compensated cirrhosis.

The purpose of this study is to assess the efficacy and safety of ABT-493/ABT-530 in adults with chronic hepatitis C virus genotype 1-6 infection and human immunodeficiency virus-1 co-infection.

This study evaluates the efficacy and safety of nasal theophylline irrigation in treating smell loss related to a viral respiratory infection. Half the participants will undergo nasal theophylline irrigation treatment while the other half will undergo placebo nasal irrigation with saline alone. All participants will have their sense of smell tested before and after 6 weeks of treatment. All participants will also be regularly asked about any potential side effects related to treatment. In addition, the first 10 participants will have their blood drawn to measure their theophylline level after 1 week of starting treatment to ensure it is not abnormally elevated.

The global COVID-19 pandemic has caused unprecedented strain on health care services around the world.The absence of specific anti-viral medications to treat the underlying infection led to a proliferation of clinical studies and trials aimed at re-purposing existing medications. Human dihydroorotate dehydrogenase (DHODH) is vital enzyme utilised by viruses to replicate in the host cell. Leflunomide, a drug that is already licenced to treat rheumatoid arthritis, is a potent inhibitor of the enzyme DHODH. Importantly, this drug has dual anti-viral and anti-inflammatory properties so it targets viral replication and suppresses host inflammatory response which plays a role at more progressive stages of infection. DEFEAT-COVID is a multi-site, international, interventional, pragmatic, parallel group design, open label, randomised CTIMP with a pilot phase that will allow to adapt procedures and assessments if required. A phase III clinical trial of leflunomide for treating COVID-19 has been registered in China, Registration number: ChiCTR2000030058). The current proposal extends the original clinical study of leflunomide in China (People's Hospital of Wuhan University) to the UK through a structured collaboration.

It is Phase 1b, 2-part, double-blind, placebo-controlled study to evaluate safety, tolerability, and pharmacokinetics of PF-07304814, in patients hospitalized with SARS-CoV-2 virus infection.

Maraviroc (MVC) is a drug, very well tolerated, it has been seen that MVC has properties of modulating the immune system, exerting an anti-inflammatory effect in different diseases. In COVID-19, very high levels of inflammation occur that cause organs and systems to be damaged. MVC could reduce this inflammation achieving a better prognosis of COVID-19.

This single-arm, open-label small interventional proof-of-concept (POC) study study aims: to assess the clinical outcomes of patients exhibiting viral respiratory infection (VRI) symptoms and seeking primary healthcare (PHC) services at the time of the COVID-19 pandemic, to assess the clinical effectiveness of the Cretan IAMA (CAPeo), a herbal extract combination, for these patients, including in terms of symptom resolution (symptom frequency, duration) and intensity), and to investigate its prophylactic effect in terms of transmission prevention for people cohabiting with the patients exhibiting VRI symptoms.
