This trial will assess the safety and efficacy of OPC-167832 combined with Delamanid and Bedaquiline in subjects with DS-TB administered for 4 months compared to rifampin, isoniazid, ethambutol, pyrazinamide (RHEZ) administered for 6 months
The purpose of this study is to conduct a multi-country, multi-site, epidemiologic study designed to assess the proportion of interferon gamma release assay (IGRA) positivity, at site level, and to build capacity to conduct a future TB vaccine efficacy study.
The 4-month daily regimen containing moxifloxacin (2HRZEM 7 / 2HRM7) of ICMR-NIRT was studied in 321 sputum positive pulmonary TB patients in a randomised clinical trial. Of the 321, there were 96% with sputum smear grading of 2+/3+ and 80% with >2 zone involvement in the chest radiograph, The sputum culture conversion at the end of intensive phase was 94%, favourable response at the end of treatment of 92% and the TB recurrence rate was 4.1%. The regimen was safe and well tolerated. The advantages of a 33% reduction in treatment duration are manifold in terms of financial and other administrative implications. As the next logical step investigators believe that the effectiveness of this shortened regimen that proved successful in our study needs to be tested in the field. Under NTEP the anti-TB drugs are offered as Fixed dose Combination (FDC).3 The HREZ intensive phase and HRE continuation phase FDC are administered to patients based on body weight category. If our proposed study proves successful, the addition of moxifloxacin tablet to the FDC of anti-TB drugs in the intensive and continuation phases of treatment would be feasible under TB program settings. Investigators propose to evaluate 4-month moxifloxacin containing daily regimen [2 months of HRZEM daily / 2 months of HREM daily (2 HRZEM 7 / 2HREM7)] in the treatment of newly diagnosed sputum smear positive pulmonary TB patients.
Pulmonary tuberculosis (PTB) is the most common cause of lung destruction, contributing to coinfections development, and Aspergillosis spp. is one of the most important. Diagnosis of chronic pulmonary aspergillosis (CPA) in PTB patients is difficult due to similarity of clinical and radiological data, especially in resource-constrained settings. Differentiation of PTB patients with singling out a group with a higher Aspergillus IgG level during the initial examination will help physicians to orient to further examination of CPA. Objectives: to determine the prevalence of aspergillosis in Koch's bacillus-positive and Koch's bacillus-negative PTB patients and antifungal resistance of Aspergillus species isolates in Central Asia countries.
Existing problem with DR TB management: Injectable regimens for longer duration with toxicity Poor adherence, treatment failures, continued transmission Need of the study: Oral regimens of shorter duration Improved treatment adherence Implementation of community-based models of care Reduction in direct costs and indirect costs of patients Improved treatment outcomes Need for shorter, tolerable and effective regimen Hence modified BPaL regimen is designed to study the newer shorter oral in varying doses of Linezolid for pre XDR Tb patients and MDR TI/NR patients
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 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.
Currently in Taiwan, most clinicians use sputum smear and culture for the diagnosis of pulmonary tuberculosis (TB) and apply nucleic acid amplification (NAA) test in a selected manner. In 2013, the World Health Organization issued conditional recommendation that Xpert MTB/RIF may be used rather than conventional microscopy and culture as the initial diagnostic test in all adults suspected of having TB. The newly published Taiwan guidelines for TB diagnosis and treatment has recommended NAA test, together with smear and culture, as the initial diagnostic test in individuals suspected of having TB. The investigators conduct a prospective study to investigate the use of Xpert MTB/RIF as the initial diagnostic test of pulmonary TB under a pragmatic trial design.
To determine if a high-dose first-line regimen is non-inferior (non-inferiority margin 10%) in terms of safety to the same regimen at regular dosing, in previously treated patients with rifampicin-susceptible recurrent Tuberculosis (TB).
