Filter by:The ERASE - TB study will be conducted in order to fill a critical unmet need for tuberculosis control. Persons who are in contact with an infectious TB case may become infected themselves. Among those who are infected, most will stay healthy but some will develop TB themselves. These people would benefit from preventive treatment, which would also stop TB from being spread to other persons. The problem currently is that it is impossible to determine with certainty who would require preventive treatment, and who will remain healthy. Out of 100 persons exposed to an infectious TB patient, only 2 will go on to have TB according to a study in Vietnam, but there are no good tests available to identify those with a risk for TB disease. Treating 100 persons to prevent 2 cases of TB is not effective, so preventive treatment is not used in adults and adolescents in Tanzania, Mozambique and Zimbabwe, where this study will be conducted, but also in many other settings. The ERASE - TB project will evaluate a number of newly developed diagnostic tests, to see which of those will be able to predict TB in persons at risk, and therefore steer preventive treatment well. For this, the investigators will invite 2,100 household contacts (HHC) of infectious TB patients, who are at least 10 years old, into the study. Everyone will be examined initially, and again in regular intervals, for 1.5 to 2 years; and whenever the participants will present with symptoms that could indicate that they develop TB. At every visit, the investigators will perform an X-ray and take some blood and urine samples to perform new candidate tests. At the first/baseline visit, all household contacts without TB will undergo a spirometry to evaluate their pulmonary function. If someone is unwell, the investigators will also examine sputum for the presence of TB bacilli. In the end, the investigators will then be able to say who of the persons in the study developed TB, and who remained healthy. From all samples taken at different timepoints, the investigators will then determine which test found TB early, and clearly distinguished between persons developing TB, and persons who would remain healthy .
The purpose of this study is to evaluate the human clinical response to BCG challenge in historically BCG-vaccinated healthy adult volunteers. It will involve 12 participants in a controlled dose escalation. Bronchoscopies will be performed 14 days post-challenge to measure BCG recovered from bronchial samples. Blood tests will be taken to look at potential immunological markers of immunity.
This study is being conducted to assess the antiretroviral activity of a fixed-drug, single tablet, combination of Bictegravir 50mg/ Emtricitabine 200mg/ Tenofovir alafenamide 25mg (Biktarvy®) dosed twice daily in HIV-1 infected, ART-naïve patients with TB co-infection receiving a rifampicin-based tuberculosis (TB) treatment regimen. This study will assess the activity of Bictegravir and dolutegravir-containing ART regimens in patients with drug-susceptible TB through 48 weeks
The purpose of this study is to assess the efficacy, safety and tolerability of a combination of bedaquiline, linezolid, cycloserine, clofazimine and pyrazinamide treatments guided by PZA sensitivity for 24 to 36 weeks in subjects with fluoroquinolone-resistant MDR-TB .
To compare treatment success (adherence and completion of treatment) and safety of 1HP with 3HP in HIV-uninfected adults and adolescents at increased risk of TB.
Across Europe and worldwide, there are many studies following groups (cohorts) of children living with human immunodeficiency virus (HIV) and other infections over time, to monitor their long-term health. Some of these infections are rare: for example, few children in Western Europe are living with HIV, so the studies often have fairly small numbers of participants. This can make it difficult to answer research questions in these cohorts and means that doctors and researchers working with these patients in different countries need to work together. This is particularly important as children are not often included in clinical trials of treatments and other interventions. The European Pregnancy and Paediatric Infections Cohort Collaboration (EPPICC) is an international network of researchers working together in this way. Researchers in the network represent cohort studies of pregnant women and children with, or at risk of, infections from across Europe and Thailand. The research focuses on infections in pregnant women and children, particularly HIV, hepatitis B and C virus, and tuberculosis, and, from 2020, novel coronavirus (COVID-19). By combining data from many cohorts, the researchers aim to answer questions that could not be answered by one study individually (for example, because a large number of pregnant women or children are needed to answer the question). This protocol focuses on the paediatric component of EPPICC's research, which focuses on the treatment of children at risk of and living with infections. For example, what medicines are used most often and how do they affect children's health? EPPICC is an observational study, which means that children do not receive any extra treatment as part of the study. Instead, children are "observed" during their routine medical care. Each cohort keeps records of the children's health collected at routine clinic visits, including information such as date of birth and sex, results of diagnostic tests, treatments received, and any illnesses or other events that the children have had. The EPPICC study combines and analyses data from all of the cohorts that take part, to answer questions about the risks and benefits of different diagnosis or treatment strategies, the long-term effects of infection and treatment during childhood and young adulthood, and regional variations (e.g. between Western and Eastern Europe) in the risk and management of infections. All of the data collected through the EPPICC Paediatric Protocol are stored securely at the Medical Research Council Clinical Trials Unit (MRC CTU) at UCL. Data collection and storage are governed by the General Data Protection Regulation. A Steering Committee guides the research to make sure it is relevant and of high quality. Public and patient involvement (PPI) may be provided by individual cohorts' own groups, as well as by the interlinked Penta organisation, which is a network of paediatricians and researchers working in infections in Europe and globally. The PPI groups help with release of the results of the research. The results are also published on the Penta Foundation's public website (https://penta-id.org/), and presented at conferences and published in Open Access scientific journals.
The new drug pyrifazimine (previous name: TBI-166) developed by the Institute of Materia Medica of the Chinese Academy of Medical Sciences which is Beijing Union Pharmaceutical Second Factory relied on is obtained by retaining the key skeleton of the lead drug clofazimine which can exert its efficacy and modification by introducing moderate polar groups structural. While the drug has strong activity against tuberculosis-sensitive bacteria and drug-resistant bacteria in vivo and in vitro, its pharmacokinetic properties and skin staining side effects have been significantly improved compared with the lead drugs, so that the drug can achieve the goal that reducing fat solubility, accelerating metabolism in the body, reducing skin staining and reducing side effects. In addition, pyrifazimine has a weak effect on liver drug enzymes, and is suitable for combined use in the clinical treatment of tuberculosis. The development of the drug is expected to provide a new method for the clinical treatment of drug-resistant tuberculosis, benefit patients, and produce good social benefits. In November 2016, the new anti-drug-resistant tuberculosis drug pyrifazimine and its tablets (formerly chemical drug registration classification 1.1) obtained the drug clinical approval issued by the CFDA (batch number: 2016L10025/2016L09987), and were approved the clinical stage research that development of drug-resistant tuberculosis adaptation. In accordance with relevant requirements of drug registration regulations, technical guidelines, etc., this project has completed the safety, tolerability, and pharmacokinetic clinical trials of a single dose of pyrifazimine tablets in healthy subjects, i.e. Phase Ia clinical trials test.
A cluster randomized controlled trial to evaluate the effect of placing Truenat platform/TB assays at primary health care clinics combined with rapid communication of results on time to treatment initiation of microbiologically confirmed TB.
The Cepheid Xpert MTB/XDR cartridge, which runs on the same platform as Xpert MTB/RIF Ultra, has been developed to detect additional resistance to isoniazid, fluoroquinolones and second-line injectable anti-tuberculosis drugs and provides results within 2 hours and on primary samples. An evaluation of the the Xpert MTB/XDR assay is currently underway in clinical settings in South Africa, India and Moldova. The TB-CAPT MTB/XDR Study will add further diagnostic accuracy and feasibility data to the evidence base for the Xpert MTB/XDR assay.
HIV-infected people have an increased risk of developing active tuberculosis (TB). To reduce the burden of TB among people living with HIV (PLHIV), the World Health Organization (WHO) recommends systematic TB screening followed by 1) confirmatory TB testing for all those who screen positive and 2) TB preventive therapy (TPT) for all TPT-eligible PLHIV who screen negative. The objective of the TB Screening Improves Preventive Therapy Uptake (TB SCRIPT) trial is to determine whether TB screening based on C-reactive protein (CRP) levels, measured using a rapid and low-cost point-of-care (POC) assay, improves TPT uptake and clinical outcomes of PLHIV, relative to symptom-based TB screening.
