Filter by:The purpose of the study is to carry out multi-country (Ukraine and Mongolia), placebo-controlled, randomized Phase III trial in patients with drug-sensitive, multi-drug resistant (MDR-TB) and TB-HIV and identify efficacy and safety of whole-cell, heat-killed Mycobacterium vaccae formulated as a pill (V7) and consequently conduct confirmatory trials in intended registration countries, such as China, Russia and South Africa, etc.
This is a Phase I, open-label, dose-escalation study with three study groups. This study will be conducted in 25 HIV negative subjects, 17 of whom will have Latent Tuberculosis Infection (LTBI) and 8 of whom will not have LTBI at study enrollment. The investigational product is AERAS-456 at a dose of 15 ug of H56 antigen with IC31 500 nmol KLK (15/500), and a dose of 50 ug of H56 antigen with IC31 500 nmol KLK (50/500). The vaccine is administered by intramuscular injection.
This study uses an ingestion sensor and a wearable sensor (worn as a patch on the skin), which are new Proteus Digital Health (PDH) technologies approved by the FDA, to collect information about patients taking their TB medications. The wearable sensor records information, which is uploaded wirelessly to a mobile device and then to a secure computer. Together the sensors and the mobile device transmitting the information to the study computer are called a digital health feedback system (DHFS), which gives healthcare providers information about when patients have taken their TB medications. The advantage of the DHFS is that patients can take their medication where and when it is convenient for them, and do not have to wait for a nurse to directly observe them taking their medication. The purpose of this study is to find out if using these new technologies works as well as the standard method of observing in person when patients take their TB medications. This study will also look at the costs of using a DHFS for TB medications, what patients and healthcare providers think about using it, and other factors that can determine when one approach works better than another. This study has two parts. For the first part of the study (Step I), patients will have an initial screening visit and then, in one two-week period, they will have 4 study visits at the UCSD AntiViral Research Center (AVRC) and routine visits from Public Health Services (PHS) workers. This part of the study is designed to confirm that the DHFS is working correctly and is accurately collecting information about each dose of medication that patients take, and to understand what patients and healthcare providers think about using the DHFS. If patients are eligible for the second part of the study (Step II) and want to continue, that will last another 8-14 weeks with an additional 4 study visits at the AVRC. In the second part of the study, patients will be randomized into one of the following two groups. Group 1: TB treatment is monitored by continued use of the DHFS Group 2: TB treatment is monitored by the standard methods used by PHS (DOT) The second part of the study is designed to compare these two methods of observing patients taking their TB medications, what the relative costs of these methods are , and the perception by patients and/or healthcare providers of the ease of use of the novel technology.
Flexible bronchoscopy is a common procedure performed by pulmonary physicians. The use of topical anesthesia, analgesia, and sedation during flexible bronchoscopy varies among physicians, institutions and geographic locations across the globe. Commonly used topical anesthetic agents before and during bronchoscopy include cocaine (4%),benzocaine (20%), tetracaine (1%), and lignocaine (1%-10%). Topical lignocaine is administered through the flexible bronchoscope in an attempt to reduce excessive coughing and patient discomfort. However, the optimal dosage and strength of topical lignocaine that should be used during fibreoptic bronchoscopy has long been a topic of controversy. In this study we compare the efficacy of 1% versus 2% lignocaine in controlling cough and pain in patients undergoing flexible bronchoscopy.
Boost vaccinations sometimes have no effect because the body has got used to the vaccine and no longer reacts to it. We are therefore investigating whether vaccinating with aerosolised MVA85A (a candidate tuberculosis vaccine) followed by a boost MVA85A intradermal vaccination (or vice versa) avoids this and increases the immune response to vaccination.
- Tuberculosis ( TB ) remains a major global public health problems and actions to ensure the diagnosis and complete treatment of all cases is the priority for the control of this disease. Despite the availability of effective anti-tuberculosis medications, there are still high levels of nonadherence to treatment. The nonadherence increases the morbidity and mortality of patients, decreases the cure rate, increases the community transmission and the increase of chronically ill patients enables the emergence of multi - drug resistant and increases treatment costs. - Despite the knowledge about different forms of cost-effective delivery of DOT (directly observed treatment), recognition of the need to establish the DOT strategy related to the context from local studies, in Colombia and in Cali we hadn't had made studies similar than this one that establish the cost and results of the current DOT delivery strategy and to identify other ways to improve adherence and cure rate for the TB patients at reasonable cost for both: health services and families - Therefore, this research aims to compare the cost -effectiveness of current DOT delivery method with an alternative extra- institutional delivery of anti -TB treatment in urban areas of Cali. A cost-effectiveness study was conducted from the institutional and familiar perspective with prospective information collection.
Isoniazid (INH) is a drug commonly used to treat tuberculosis (TB) worldwide. Sometimes, the bacteria that cause TB can become resistant to INH. Resistance means that bacteria have adapted to a drug and are able to live in the presence of the drug. When TB becomes resistant to INH, INH does not work as well at fighting the bacteria. This study treated people with INH-resistant TB with different doses of INH to see if INH can still fight the bacteria if the dose is increased. We evaluated how well the drug works at higher doses for participants who have resistant TB as well as how well the drug works at regular doses for participants who have TB that is not resistant. The study also evaluated the safety and tolerability of the different doses of INH. Tolerability is how well people can put up with the side effects of a drug. Using increased doses of INH to treat TB that is resistant to INH is experimental and has not been approved by regulatory authorities. While there is some evidence that this approach will work, this has not yet been proven.
The overall research objective is to evaluate the impact of implementing a reminder system for medical providers to improve TB case-finding and isoniazid preventative therapy (IPT) for adults living with HIV in western Kenya
The purpose of this study is to examine the colchicine concentration before and after the administration of rifampicin.
The purpose of this study is to determine the safety, tolerability, and immunogenicity in BCG-vaccinated healthy adult subjects of an investigational vaccine being developed for the prevention of pulmonary tuberculosis.
