Linezolid Instead of Ethambutol in Treatment of Drug-susceptible Tuberculosis

Pulmonary Tuberculosis Without Resistance to Rifampicin

The current standard short-course treatment for pulmonary TB requires 6 months to complete. This long duration of treatment increases the likelihood of side effects while decreasing patients' adherence to anti-TB drugs. Linezolid showed considerable efficacy against refractory multidrug-resistant TB. Considering the marked anti-TB effects of linezolid as well as the possible adverse effects of its long-term use, it is rational to use linezolid instead of ethambutol for the first 4 weeks of treatment for drug-susceptible pulmonary TB. Through randomized controlled trial, the investigators will evaluate the hypothesis that the use of linezolid instead of ethambutol will increase the sputum culture conversion rate by 15% after 2 months of treatment. Patients with TB without resistance to rifampicin will be randomized to the following three arms at a 1:1:1 ratio: Arma 1 (control arm), Arm 2 (linezolid for 2 weeks instead of ethambutol), Arm 3 (linezolid for 4 weeks instead of ethambutol)Primary outcome will be sputum culture conversion rate after 2 months of treatment (liquid media).

Safety and Efficacy of Blocking IL-4 With Pascolizumab in Patients Receiving Standard Therapy for...

TuberculosisPulmonary

New approaches are needed to achieve more rapid elimination of dormant mycobacteria and thereby shorten treatment for drug-sensitive and drug-resistant tuberculosis (TB). Dormant mycobacteria are relatively resistant to antibacterial drugs and approaches that enhance immune clearance have the potential to be more effective. Interleukin-4 (IL-4) is a key cytokine in the immune response to TB that may impair the clearance of mycobacteria. We hypothesize that pascolizumab, an anti-IL-4 monoclonal antibody, might be of value as an adjunct to standard treatment. The aims of this trial are to determine whether administration of pascolizumab as an adjunct to standard combination treatment for drug-sensitive TB produces changes in one or more parameters of bacterial or host response (including bacterial clearance, host clinical status, immune response, bacterial and host transcriptomics, lung imaging) that may indicate potential for enhanced sterilization and to confirm the safety of blocking IL-4 (previously demonstrated in healthy volunteers and patients with asthma) in patients with TB.

RIPE vs RIPE Plus N-acetylcysteine in Patients With HIV/TB Co-infection

TuberculosisPulmonary1 more

Although tuberculosis is a treatable disease, it is currently the infectious disease with the highest mortality in the world. It is estimated that one-third of the world's population is infected. HIV is the main predisposing factor for TB development. The Brazilian Ministry of Health and the World Health Organization recommends that patients should initially be treated orally with RIPE - rifampicin (R), isoniazid (I), pyrazinamide (P) and ethambutol (E). The N-acetylcysteine (NAC) first benefit was reported during the 1960s, when it proved to be an effective mucolytic agent in individuals with cystic fibrosis. Later, a new role arose when investigating its therapeutic potential in acetaminophen intoxication. Cleavage of the acetyl group makes cysteine available for later incorporation into glutathione synthesis, decreased in hepatic injury caused by acetaminophen. This mechanism causes NAC to have an indirect antioxidant effect, which aroused an interest in studying the effect in diseases that occur with oxidative stress. TB and HIV/Aids are also diseases with chronic inflammation. The present study aims to evaluate the effects of NAC as a adjuvant therapy in the treatment of TB. This is a phase II randomized clinical trial in which the safety and tolerability of NAC as adjunctive therapy for TB treatment will be assessed. Fifty-six patients will be randomized into two groups. The first group will receive the standard tuberculosis treatment as recommended by the Brazilian Ministry of Health (RIPE); the second will receive in addition to this treatment 1200mg of NAC per day for two months. In this way, microscopy and culture conversion rate to mycobacteria at 8 weeks, levels of glutathione and biomarkers of immune activation and inflammation in case of TB with or without NAC will be monitored.

Early Bactericidal Activity Safety Pulmonary Tuberculosis Pyrifazimine (TBI-166)

Sensitive Pulmonary Tuberculosis

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.

Multicenter Trial for the Evaluation of a Fixed Dose Combined Tablet for the Treatment of Pulmonary...

Tuberculosis

The use of fixed-dose combined (FDC) drugs in the treatment of tuberculosis by National Tuberculosis Programmes has been recommended by both the International Union Against Tuberculosis and Lung Disease (The Union) and the World Health Organisation. The advantages of FDC drugs include preventing the emergence of drug resistance due to monotherapy, reducing the risk of incorrect dosage, simplifying procurement and prescribing practices, aiding adherence and facilitating directly observed treatment. Recent bioavailability studies of four-drug FDC tablets have demonstrated satisfactory results. In this study, we are testing the efficacy of this compound, when given in the initial intensive phase of treatment of patients with newly diagnosed smear positive pulmonary tuberculosis. This will be followed by four months treatment with a two-drug FDC of rifampicin and isoniazid.

A Controlled Trial of a 4-Month Quinolone-Containing Regimen for the Treatment of Pulmonary Tuberculosis...

Tuberculosis

Tuberculosis is currently treated with a 6-month course regimen. During this time many patients might fail to adhere to treatment and default, increasing the risk of recurrent disease which might be multidrug resistant. A shorter duration of treatment is expected to provide improved patient compliance and at least equal or better clinical outcome. The aim of the trial is to evaluate the efficacy and safety of a gatifloxacin-containing regimen of four months duration for the treatment of pulmonary tuberculosis,
