Filter by:This study will assess the next generation of blood tests for latent TB infection, which may be able to indicate how treatment is working as well as in diagnosis infection.
This is a phase I randomized, double blind clinical trial designed to evaluate the safety, tolerability and immunogenicity of the ID93 recombinant protein antigen alone or formulated with GLA-SE or AP10-602 adjuvant in 70 healthy adults 18-49 years of age. Subjects will receive a total of 3 doses administered intramuscularly on Days 1, 29 and 57. Subjects will be monitored for approximately 422 days (365 days following the third study injection), including safety laboratory analyses done just prior to and 7 days following each study injection. Blood samples will be obtained for immunological assays (Luminex, intracellular cytokine staining at Days 1 and 71, and antibody analysis at Days 1 and 85). The primary objective is to evaluate the safety and tolerability of 10 µg ID93 + 5 or 10 µg AP10-602 compared to 10 µg ID93 + 5 µg GLA-SE and 10 µg ID93 alone following three consecutive intramuscular injections administered on Days 1, 29 and 57.
Tuberculosis (TB) is a global challenge and for the increasing epidemic of multi-drug resistant (MDR)-TB there is restricted treatment options. This calls for research of new immune-modulating treatment strategies that can strengthen the patients immune system to better fight the TB bacteria. The pro-inflammatory, but still immunosuppressive mediator prostaglandin E2 (PGE2) is produced by cyclooxygenase-2 (COX-2) in inflamed infected tissue. Studies from both human and animal models show that COX-2 inhibitors (COX-2i) can improve the immune system and strengthen vaccines responses. Hypothesis 1. A hyperactive COX-2/PGE2 signal system in active TB causes down-regulated immune responses that favour TB survival, but this can be abrogated by COX-2i. 2. TB-specific immunisation with targeted antigens presented as a therapeutic TB vaccine and enhanced by COX-2i will improve immune-mediated host clearance of TB. 3. Combinations of COX-2i and a therapeutic TB vaccine to conventional anti-TB chemotherapy offer new treatment modalities for TB, including MDR/XDR-TB. Approach to test the hypothesis 1. Study design: 4-arm, open and randomized clinical intervention trial of patients starting treatment for active TB in specialized Norwegian TB centres and where two arms will receive the COX-2i etoricoxib with and without a TB vaccine, one arm vaccine only and the last arm serve as control receiving only standard anti-TB therapy. For safety precautions, only patients bearing sensitive TB strains are included and study arms will be sequentially introduced. 2. In a mouse model examine in more detail the effects of reversion of chronic inflammation with COX-2i locally in tissue and the interplay with TB vaccine responses, immune regulation, correlates of protection and survival in a well-characterized model for TB-exposed mice.
The study is a single centre, phase I, double-blind, randomized, placebo-controlled trial that explored the safety and immunogenicity of 2 doses (Day 1 and Day 21) TB/FLU-04L tuberculosis vaccine versus matched placebo in BCG-vaccinated healthy adult subjects aged 18-50 years.
This is a prospective study to assess the yield of pleural biopsy obtained with the routine flexible thoracoscopic biopsy forceps versus that obtained with a flexible cryoprobe during semirigid thoracoscopy
Comparison of 68Ga-AlfatideII and 18F-FDG in differential diagnosis effectiveness towards the solitary pulmonary nodules of lung cancer or tuberculosis.
Assess the Efficacy of HUEXC030 as Add-on Excipient to Eradicate Anti-Tuberculosis Drugs Induced Hepatic Injury ( ATDH ) in Subjects with Pulmonary Tuberculosis
The purpose of this study is to evaluate the safety and immunogenicity of ID93 + GLA-SE vaccine when administered to adult pulmonary Tuberculosis (TB) patients, following successful completion of TB treatment with confirmed bacteriologic cure, in preparation for a future Phase 2b prevention of TB recurrence trial in the same population.
This is a prospective descriptive and pharmacokinetic study will be conducted among newly diagnosed patients registered in the two SMRU TB clinics located on the Thai-Myanmar border. This study aims to recruit (1) 30 adults with HIV co-infection and (2) 30 adults without HIV co-infection in one year. Patients will be given the standard 6 month anti-TB drugs as per WHO guidelines.
