Active clinical trials for "Infections"

The purpose of this study is to evaluate the safety and antiviral activity of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) with and without ribavirin (RBV) in patients with chronic hepatitis C virus genotype 1b (HCV GT1b) infection without cirrhosis.

The primary objective of this study is to evaluate the safety and efficacy of a Response Guided Therapy of boceprevir 800 mg dosed three times a day (TID) orally (PO) in combination with Peginterferon (either alpha 2b or alpha 2a) and Ribavirin in HIV/HCV genotype 1 infected patients that failed to previous HCV therapy.

Patients who have undergone lung transplantation are at an increased risk of developing chest infections due to long-term medication suppressing the immune response. In other chronic lung diseases such as cystic fibrosis (CF) and bronchiectasis, inhaled, nebulised mucolytic medication such as dornase alfa and isotonic saline are often used as part of the management of lung disease characterized by increased or retained secretions. These agents act by making it easier to clear airway secretions, and are currently being used on a case-by-case basis post lung transplantation. To the investigators knowledge, these agents have not been evaluated via robust scientific investigation when used post lung transplant, yet are widely used in routine practice. Patients post lung transplant must be investigated separately as they exhibit differences in physiology that make the clearance of sputum potentially more difficult when compared to other lung diseases. Lower respiratory tract infections are a leading cause of hospital re-admission post lung transplant. Therefore, this highlights the need for a randomized controlled trial. The aim of this study is to assess the efficacy of dornase alfa, compared to isotonic saline, in the management of lower respiratory tract infections post lung transplant. Investigators hypothesize that dornase alfa will be more effective than isotonic saline. The effect of a daily dose of dornase alfa and isotonic saline will be compared over a treatment period of 1 month. Patients admitted to hospital suffering from chest infections characterized by sputum production post lung transplant will be eligible for study inclusion. Patients will be followed up through to 3 months in total to analyze short-medium term lasting effect. Investigators wish to monitor physiological change within the lung non-invasively via lung function analysis whilst assessing patient perceived benefit via cough specific quality of life questionnaires. These measures will be taken at study inclusion and repeated after 1 month and 3 months. Day to day monitoring will be performed via patient symptom diaries, incorporating hospital length of stay and exacerbation rate. The outcomes of this study have the potential to guide clinical decision-making and highlight safe and efficacious therapies.

The purpose of this study is to assess the efficacy and safety of J022X ST for prevention of Recurrent Upper-Respiratory Tract Infections (RURTI) compared to placebo in children of younger age who develop infectious diseases more frequently than other children of this age in general.

TD-1607, administered intravenously as multiple ascending doses, will be investigated in healthy subjects to assess its tolerability, safety, and pharmacokinetics.

The purpose of this study is to determine if there is comparable efficacy between carbocisteine and a protective cough syrup from natural ingredients in children's cough due to upper respiratory tract infections (URTI) such as the common cold. The hypothesis is that protecting the throat is very useful in decreasing cough severity, both day and night, without needing to subdue such an important reflex as cough, and without only acting on mucous fluidification, especially in children where sedation and excessive fluidification is dangerous. The research hypothesis is that the protective (Grintuss) Syrup relieves cough (frequency, intensity, degree of disturbance due to nocturnal cough, and improves the quality of sleep of the child) as much as or more than the carbocysteine syrup usually used to treat children (Syr Mucolit).

This trial is a pilot study to determine the feasibility of a randomized clinical trial comparing a treatment algorithm consisting of a limited number of clinical parameters, rapid molecular viral diagnostics, and serum procalcitonin testing to standard of care for directing antibiotic use in patients with non-pneumonic lower respiratory tract infection. The reduction in antibiotic use in those subjects randomized to the treatment algorithm compared to those randomized to standard care will be determined.

We are evaluating the effect of methylene blue and visible light activation on the microbiome of the skin.

A pilot study to compare the efficacy and safety of raltegravir-based versus efavirenz-based combination therapy in treatment-naïve patients with HIV-1 infection.

Patients enrolled on this study will have received a stem cell transplant. After a transplant, while the immune system grows back the patient is at risk for infection. Some viruses can stay in the body for life and if the immune system is weakened, like after a transplant, they can cause life threatening infections. Patients enrolled on this study will have had an infection with one or more of the following viruses - Epstein Barr virus (EBV), cytomegalovirus (CMV), BK virus, JC virus, adenovirus or HHV6 (Human Herpes Virus 6). Investigators want to see if they can use a kind of white blood cell called T cells to treat infections of these viruses after a transplant. Investigators have observed in other studies that treatment with specially trained T cells has been successful when the cells are made from the transplant donor. However as it takes 1-2 months to make the cells, that approach is not practical when a patient already has an infection. Investigators have now generated multivirus-specific T cells (VSTs) from the blood of healthy donors and created a bank of these cells. Investigators have previously successfully used frozen multivirus-specific T cells from healthy donors to treat virus infections after bone marrow transplant and now have improved the production method to make it safer and target more viruses. In this study, investigators want to find out if they can use these banked VSTs to fight infections caused by the viruses mentioned above.
