Filter by:The purpose of this study is to evaluate the efficacy of 48-week study intervention with JNJ-73763989+JNJ-56136379+nucleos(t)ide analog (NA) regimen compared to NA alone assessed by HBsAg levels. This study is part of HepB Wings Platform Trial (PLATFORMPAHPB2001).
Oropharyngeal squamous cell carcinoma (OPSCC) is now the most frequently diagnosed head and neck cancer in Denmark which is mainly due to the increase of Human Papillomavirus (HPV). Patients with HPV-positive OPSCC have a significantly higher survival rate compared to HPV-negative OPSCC. The traditional primary treatment modality in Denmark is Intensity Modulated Radiation Therapy (IMRT), and in advanced stages in combination with chemotherapy. Since 2009, Transoral Robotic Surgery (TORS) has enabled surgeons to perform minimally invasive surgery as an alternative to standard radiotherapy treatment which is considered the primary treatment for OPSCC in many countries. There is a lack of randomised trials comparing long-term functional outcomes after TORS or IMRT. Current data are mostly derived from retrospective studies with selection bias. However, several small retrospective studies have shown promising results when comparing the two treatment modalities in favour of TORS with regards to treatment related swallowing function and quality of life (QoL) without compromising survival outcomes. This study aims to evaluate the early and long-term functional outcomes following two treatment arms 1) TORS combined with neck dissection and 2) IMRT±concurrent chemotherapy with a special focus on swallowing-related QoL.
This study was to assess the safety and efficacy of Seraprevir in combination with sofosbuvir in patients with Hepatitis C (HCV) genotype2,3,6. Efficacy was assessed by the rate of sustained viral response (SVR) 12 weeks after the discontinuation of therapy (SVR12).
Bronchiolitis obliterans (BO) is the well-known manifestation of the chronic pulmonary graft-versus-host disease(GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). The pathophysiology of BO is, however, poorly known. The available data strongly support the role of respiratory viruses, in particular paramyxoviruses (parainfluenzae virus (PIV), respiratory syncytial virus, metapneumovirus). It is likely that the alloimmune response triggered by the respiratory virus is inadequate and leads to the peribronchiolar fibrotic process. The objective is to analyze the kinetics of profiles of the blood and respiratory host responses resulting from a high or low parainfluenza respiratory infection, in order to evaluate if the occurrence of a BO is associated with a specific signature We will evaluate the predictive signature of a BO after a parainfluenza virus infection by characterizing the differences between the patients evolving and those not evolving to a BO at 2 months after the infection.
The purpose of this study is the evaluation of PAH in patients, who are treated with DAA medication for HCV infection.
In summary, in this project the investigators propose to study the proviral DNA genotyping to implement a lower cost and wider than the commercial systems currently in use, in order to analyze all HIV genes that are therapeutic targets of antiretroviral drugs. Using HIV proviral DNA we can obtain information for: HIV-1 Viral Tropism, Mutations associated to Integrase Inhibitors, Mutations associated to Transcriptase reverse Inhibitors, Mutations associated to Protease Inhibitors, and Mutations associated to GP41 Inhibitors. Along with this the investigators propose to validate the proviral DNA as starting material for genotyping which is independent of the patient's viral load and achieve a greater number of patients living with HIV have access to this important test that is essential in monitoring the HIV infection. 3.2 RESEARCH QUESTIONs Is proviral DNA a genetic compartment suitable for carrying out a genotypic resistance test in patients with low or undetectable viral load? Does proviral DNA have the same clinical validity that RNA? 3.3.- HYPOTHESIS A resistance genotyping test carried out by Proviral DNA detects the same mutations associated to resistance that viral RNA. 3.4.- OBJECTIVES: General/Specific General objective Develop a methodology to assess the proviral HIV-1 DNA or RNA as the genetic material for genotyping assays in genes that are targets of pharmacological interest as TR reverse transcriptase and protease (PRO), Integrase or GP41 Inhibitors and HIV tropism. Specific Objectives 1. Carry out genotyping by proviral DNA and compare it with the same genes genotyping performed with viral RNA. 2. Once the correlation between proviral DNA and RNA has shown, standardize a method to use the technique for clinical use in monitoring HIV patients according to each patient's needs. RNA for patients with viral load above 1,000 copies/mL. Proviral DNA for patients with low or undetectable viral load.
The primary objective of this study is to determine if a single intravenous (IV) dose of clesrovimab when administered at 1 of 4 dose levels results in a reduction in viral load after intranasal inoculation (with RSV A Memphis 37b) compared to IV placebo. It is hypothesized that at least 1 of the 4 dose levels of clesrovimab given prior to inoculation will reduce the area under the viral load-time curve (VL-AUC) from Day 2 through Day 11 (inclusive) after viral inoculation (Study Day 31 through Day 40) compared to placebo.
Valacyclovir has replaced acyclovir in many clinical scenarios. Pharmacokinetic data support the use of oral valacyclovir in children, but practical problems exist in children having to take adult-dose tablets. A formulation with acceptable palatability, good pharmaceutical quality and possibility of flexible dosing is developed. Pharmacokinetic data of this formulation is missing. The present study investigates the pharmacokinetics of valacyclovir oral solution in children by determine the area under the curve (AUC0-12), time above critical concentration (Ccrit), Cmax and Tmax of acyclovir. Secondary, the safety profile of a single dose of valacyclovir oral solution will be determined.
This phase 3 clinical study is a randomized, observer-blind, comparator-controlled, multicenter study of QIVc versus a US-licensed comparator QIV in children 6 months through 47 months of age. The purpose of this study is to demonstrate that vaccination with QIVc elicits an immune response that is noninferior to that of a US-licensed comparator QIV containing the same virus strains, in children 6 months through 47 months of age.
The purpose of this two-part designed study is to assess in the setting of a planned early interception of pediatric RSV disease, early viral and disease kinetics (observational stage) and the antiviral effects of an Respiratory Syncytial Virus (RSV) fusion inhibitor, JNJ-53718678 (interventional stage). In the observational stage the infant is closely monitored for early symptoms by the parent(s)/caregiver(s) and thus may be brought in for diagnosis earlier than in the typical setting.
