Filter by:In the tests, small sample of clinical study about Recombinant Mycobacterium Tuberculosis Allergen ESAT6-CFP10 ( Recombination EC Allergen） healthy adults was carried out. 24 healthy adults were included as study objects, they were randomly divided into four groups of different Recombinant Allergen EC dose (1, 5, 10μg/mL, maximum tolerated dose 20μg/mL, 6 person/dose) for single arm intradermal injection. The main examination items :vital signs (breathing, heart rate, blood pressure, body temperature ) of each volunteer at 15min, 30min, 1h, 2h, 4h, 8h, 24h, 48h, 72h, 96h after injection, skin reactivity (redness and/or induration) diameter of injection sites,local reaction ( rash, pain, itching, and skin and mucous membranes ) ,a variety of adverse events,routine blood,routine urine, liver and kidney function, ECG and chest X-ray films before and 7 days after intradermal injection . Preliminary evaluation of safety and tolerability of Recombinant Allergen EC applied in humans, which can provide a safe dosage range for phase II clinical study.
The purpose of this study is to compare two different methods of intensified tuberculosis (TB) case finding in the community. These methods all involve the use of a mobile clinic to reach people with TB symptoms who are not able to readily access clinic services. A standard diagnostics package consisting of smear microscopy and culture (with smear result available the next day) will be compared with a novel diagnostics package involving point-of-care sputum GeneXpert MTB/RIF performed at a mobile or conventional clinic (with same day result), sputum culture, and lateral flow urinary lipoarabinomannan (LAM) testing (in HIV +ve subjects only). The primary outcome is a comparison between the number of culture +ve subjects on TB treatment in each group at the end of two months. A secondary aim is an evaluation of the accuracy and feasibility of GeneXpert performed in a mobile clinic. Additional study aims include using chest X-rays obtained during the study to develop and validate of an computer-aided diagnosis (CAD) software package for TB (together with collaborators in the Netherlands), as well as establishing whether LAM is detectable at sub-ELISA concentrations in the urine of those with TB.
Mycobacterium Vaccae for Injection (Trade Name "Vaccae") is a kind of bio-products developed by Anhui Zhifei Longcom Biopharmaceutical Co.,Ltd.,and got "The New Drug Certificate "in 1999. Vaccae has been approved for adjuvant therapy of tuberculosis(TB), and is also the only recommended drug in TB immunotherapy by WHO. It was approved for production and sale by Anhui Zhifei Longcom Biopharmaceutical Co.,Ltd. in 2001, and got favourable comment in therapy of tuberculosis. The purpose of this study is to add new indications for Vaccae, mainly to prevent Tuberculosis for high risk groups of Tuberculosis Infection . In December 2012, China Food and Drug Administration approved of the plan "Phase III Clinical Study of Efficacy and Safety of Mycobacterium Vaccae to Prevent Tuberculosis in high risk groups of Tuberculosis Infection". In the test, 10,000 cases whose skin tests of PPD are strongly positive are enrolled. Using random, double-blind, and placebo-controlled methods, the study is carried out to evaluate the efficacy and safety of Vaccae in preventing Tuberculosis. Meanwhile, in this test, TB incidence and degree of pathological changes of experimental group are lower than that of control group, and no drug-related SAEs are reported in treatment groups.
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.
