FIND and partners intend to address the need for a multi- and extensively drug-resistant tuberculosis (M/XDR-TB) diagnostic solution for patients in settings with a high burden of drug-resistant tuberculosis (DR-TB) though the development, evaluation and introduction of an Xpert MTB/XDR assay
Tuberculosis (TB) has been one of the top 10 causes of death worldwide from a single infectious agent, ranking above HIV/AIDS. Management and eradication of this disease is being hindered by the emergence of multidrug-resistant TB (MDR-TB) and extensively drug resistant TB (XDR-TB). Globally, there were estimated 10.4 million cases of TB and 490,000 cases of MDR-TB in 2016. China accounts for around 8.6% (0.895/10.4 million) of the global TB burden, ranking third in the top 3 countries (India, Indonesia, China) with the highest number of TB cases and ranking first with the largest number of MDR/ Rifampin-Resistant (RR)-TB cases. The treatment success rate for MDR-TB using the 18-24-month conventional World Health Organization (WHO) regimen was estimated to be about 54% worldwide and 41% for China in 2016, which remains unacceptably low. The poor MDR-TB treatment success rates suggest that current drug regimens are suboptimal. In addition, they are costly with a high pill burden, as many drugs, with significant potential for adverse events, are given for a long duration. These factors also inhibit good treatment compliance with further negative impact on treatment outcomes. According to previous studies, treatment outcomes of MDR-TB could be affected by drug resistance of pivotal drugs in MDR-TB regimen, such as fluoroquinolones, second-line injectable agents and pyrazinamide. The available drug-resistance information could help physicians decide the proper regimens for MDR-TB patients, which may prevent the useless prescription and evitable adverse. Therefore, the individualized regimen based on the resistance profile of the bacteria and patients' drug tolerance should be aimed for high-quality treatment for MDR-TB in the future. A precision individualized treatment approach based on the rapid molecular drug susceptibility tests of second line drugs may assist clinicians in making more suitable regimen and improve the treatment outcome of MDR-TB. Also, precision regimen offers the opportunity to improve treatment of drug-resistant tuberculosis through reduced toxicity while reducing the risk of resistance amplification and further transmission at a population level. The purpose of this research is to assess the feasibility and effects of individualized regimen that is guided by rapid molecular drug susceptibility tests of key second-line drugs through next generation sequencing. Meanwhile, the study will evaluate a short course regimens of drugs among "simple MDR-TB" patients who are proven to be sensitive to fluoroquinolones ,injectable second-line drugs and pyrazinamide.
Brief summary: Allogeneic γδT cells from healthy donor will be administrated intravenously to patients with the MDR-TB，and then the safety and efficacy of γδT cells will be evaluated.
The purpose of this study is to compare the efficacy and safety of 26 weeks of delamanid (DLM) versus 26 weeks of isoniazid (INH) for preventing confirmed or probable active tuberculosis (TB) during 96 weeks of follow-up among high-risk household contacts (HHCs) of adults with multidrug-resistant tuberculosis (MDR-TB) (index cases). High-risk HHCs are those with HIV or non-HIV immunosuppression, latent TB infection, and young children below the age of 5 years.
Deltyba Registry aims to collect the usage information of Deltyba which could be a factor of developing resistance in actual clinical settings.
Observational, multi-centre, prospective study to investigate the feasibility of centralized TDM of moxifloxacin and levofloxacin in MDR-TB patients by determining turn-around time between sampling and receiving dosing advice. In addition, the effect of TDM will be evaluated by comparing treatment results of prospective patients receiving TDM with historical controls without TDM.
To evaluate the efficacy, safety and tolerability at 8 weeks (2-months), 52 weeks (12-months), and 104 Weeks (24-months) post the start of the following treatment regimens in participants with: Drug Sensitive TB (DS-TB) patients given BPaMZ for 17 Weeks ( or 4 months) vs. Standard HRZE/HR treatment given for 26 weeks (or 6 months) and Drug Resistant TB (DR-TB) patients given BPaMZ for 26 Weeks (or 6 months)
Recent advances in molecular diagnostics of tuberculosis, especially the GeneXpert Mycobacterium tuberculosis/Rifampicin test have reduced the time to diagnose Rifampicin Resistant Tuberculosis (RR-TB) but only rifampicin resistance is diagnosed, leading to presumptive diagnosis of resistance to isoniazid and maybe other drugs. Thus in low and middle income countries, most drug sensitivity testing relies on phenotypic drug resistance testing, which takes up to 4 months. In addition, currently, culture on monthly sputum samples is recommended by the World Health Organization for follow-up of Rifampicin Resistant Tuberculosis patients under treatment. Unfortunately, culture is often not locally available and samples need to be transported from field to culture laboratories. The associated transport delays lead to high rates of contamination and false negative culture, particularly in laboratories in low resource settings. Many gaps for the diagnosis and management of RR-TB patients still need to be addressed and the DIAMA project (DIAgnostics for Multidrug resistant tuberculosis in Africa) study aims to address some of them.
This study is a U.S.-based, 1 site (with 4 clinical settings), randomized controlled trial (with funding from the Centers for Disease Control and Prevention's (CDC) Antibiotic Resistance Solutions Initiative) that will be implemented to evaluate traditional directly observed therapy (DOT) and electronic forms of DOT (eDOT) for tuberculosis (TB) treatment. The trial will assess whether eDOT that employs electronic communication methods, such as video via computer or cellphone, is a non-inferior approach to monitor TB treatment adherence, compared to traditional in-person DOT (ipDOT), in which a trained person is in the physical presence of patients as anti-TB drugs are ingested. ipDOT is the single best intervention proven to be successful when it comes to TB patients' adherence to therapy (which reduces risk of acquired drug resistance). However, ipDOT is resource intensive and many times challenging to facilitate in-person. If eDOT is found to be non-inferior to ipDOT, health departments and other clinicians might be able to provide eDOT to certain populations of TB patients in a more flexible and potentially cost-saving manner.
This observational study will examine the safety and efficacy of bedaquiline and delamanid used (individually, not together) in routine, multidrug regimens for treatment of MDR-TB. The information gathered in this study will inform doctors how best to use these TB drugs in the future.
