Active clinical trials for "Tuberculosis, Pulmonary"

Primary Objective: To compare, at the completion of the follow-up phase, the clinical and bacteriologic relapse rates associated with the two study regimens. Secondary Objectives: To compare the clinical and bacteriologic failure rates of the two study regimens at the completion of the study phase therapy. To compare the clinical and bacteriologic response rates for the two study regimens among patients who began study phase therapy with signs and symptoms of tuberculosis or cultures positive for M. tuberculosis. To compare the toxicity associated with the two study regimens by comparing discontinuation rates due to adverse events and occurrence rates of signs and symptoms associated with adverse events during study phase therapy. To compare mortality rates of the two study regimens. To compare the rates of completion of therapy within 22 weeks for the two study regimens. To compare the rate of development of drug-resistant tuberculosis in the two study regimens among study patients classified as treatment failures or relapses. To compare all of the above performance characteristics for the two study regimens in a small subset of HIV seropositive patients. To compare attitudes and beliefs about participation in this study between patients who complete study therapy and those who fail to complete study therapy.

The purpose of this study is to assess the efficacy and safety of Chinese medicine Qinbudan in Patients Receiving Standard Combination Therapy for Retreatment Pulmonary Tuberculosis.

The purpose of this study is to evaluate the mycobactericidal activity, safety, tolerability, and pharmacokinetics of 6 doses of linezolid: 300 mg once per day, 300 mg twice per day, 600 mg once per day, 600 mg twice per day and 1200 mg once per day administered orally for 14 consecutive days or 1200 mg administered three times per week for two weeks in adult subjects with newly diagnosed drug-sensitive, smear-positive pulmonary tuberculosis.

This is a prospective, randomized, parallel, controlled study comparing the efficacy and outcomes in the retreatment of pulmonary Tuberculosis (TB) in Guangzhou in a group using pretreatment susceptibility tests in selection of chemotherapy regimens and that in another group without using pretreatment susceptibility test results. The investigators hypothesize that selecting drug treatment on the basis of known susceptibility tests would lead to improved outcome compared with empiric treatment.

The current standard management strategy for drug-sensitive pulmonary tuberculosis (TB) is to treat with multiple drugs for 6 months, although patients often fail to adhere to the long treatment, leading to poor clinical outcomes including drug resistance, which is expensive and difficult to treat. The TRUNCATE-TB trial evaluates an alternative strategy (the TRUNCATE-TB Management Strategy) comprising treatment for 2 months (8 weeks, extended to 12 weeks if inadequate clinical response) with a regimen predicted to have enhanced sterilising activity ("boosted regimen") and monitoring closely after treatment cessation. Those who relapse (predicted to be always drug sensitive and likely to occur early) will be retreated with a standard 6 month regimen. The trial is a randomized, open-label, multi-arm, multi-stage (MAMS) trial to test the hypothesis that the TRUNCATE-TB Management Strategy is non-inferior to the standard management strategy in terms of longer-term outcomes (clinical status at 96 weeks). If non-inferiority is demonstrated then the advantages/disadvantages of implementing the strategy will be explored in secondary outcomes (from patient and programme perspective). The trial will evaluate the TRUNCATE-TB Management Strategy with 4 potential boosted regimens (180 per arm, total 900 with the standard TB management strategy arm). The boosted regimens include new drugs (licensed drugs, repurposed from other indications) and optimized doses of standard drugs, selected based on consideration of maximal sterilising effect, absence of drug-drug interactions, as well as safety and tolerability over a period of 2 months

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)

The purpose of this study is to assess the safety, tolerability, and pharmacokinetics of pravastatin adjunctive therapy when combined with the standard tuberculosis (TB) treatment regimen in adults with TB.

This study is an open-label, randomized, controlled, multi-center Phase IIB dose-finding trial to evaluate the safety, tolerability, pharmacokinetics and exposure-response-relationship of different doses of sutezolid (STZ) in combination with bedaquiline, delamanid and moxifloxacin in adults with newly diagnosed, uncomplicated, smear positive and drug sensitive pulmonary tuberculosis. Participants will be randomized to one of five arms containing bedaquiline, delamanid and moxifloxacin with different doses of STZ (0mg, 600mg once daily (OD), 1200mg OD, 600 mg twice daily (BD), 800 mg BD). Study treatment duration will be three months, followed by a follow-up period of 2 weeks. The primary objective is to identify the optimal dose of sutezolid to be used in subsequent studies that provides the best efficacy at acceptable safety of the drug by describing the safety, tolerability and exposure toxicity relationship of sutezolid (and its main metabolite) given over three months, in combination with standard-dose bedaquiline, delamanid and moxifloxacin, compared to standard-dose bedaquiline, delamanid and moxifloxacin alone.

The primary purpose of this study is to assess the safety and efficacy of interferon-gamma by subcutaneous injection in complex treatment of patients with co-infection of HIV and pulmonary tuberculosis and to determine the rational of its use.

SQ109 was developed with the aim of shortening TB treatment and providing new drugs for resistant TB. The drug has demonstrated efficacy in toxicology studies and an acceptable safety profile in first-in-man studies. The objective of this study is to evaluate the extended early bactericidal activity (EBA), safety, tolerability, and pharmacokinetics of several doses of SQ109 with or without Rifampicin (RIF) for 14 days in adults with newly diagnosed, uncomplicated, smear positive, pulmonary TB.
