Active clinical trials for "Tuberculosis, Pulmonary"

ISIT-TB Prototype is a diagnostic assay based on a transcriptional blood signature suggestive of the detection of Mycobacterium tuberculosis.

Undernutrition is a leading global risk factor of tuberculosis (TB) and a prevalent comorbidity associated with TB. In Benin, the National TB Program systematically provides nutritional support to all persons with TB (PWTB), distributing prepared foods to hospitalized patients and food baskets during outpatient care. In Togo, the PWTB population is similar to that of Benin; however, Togo does not have a systematic program in place to provide nutritional support to these patients. The investigators will perform a prospective cohort analysis using anonymized TB patient data from the National TB Programs of Benin and Togo. Participants enrolled in Benin will receive nutritional support from the hospital while those enrolled in Togo will not. Participants in Togo who do not receive nutritional support will serve as a control. Unfavorable outcomes in both groups such as treatment failure, death, or relapse will be compared. The results from this study should help to shape TB programs in the future by incorporating nutritional support.

Although effective therapy for tuberculosis is available, TB continues to cause significant problems worldwide, and rates of multi-drug resistant (MDR) TB cases are on the rise. A major obstacle to the control of TB is poor adherence with lengthy (usually 6 months) and complicated treatment regimens. Incomplete TB treatment can lead to serious consequences such as increased severity of illness and death, prolonged infectiousness and transmission in the community, and the development of drug resistance. The development of new treatment strategies with more stronger drugs could lead to shorter and simpler regimens. A TB treatment regimen that allowed treatment duration to be meaningfully decreased would have important public health implications. This trial will compare the effect and safety of a new oral regimen to that of the standard regimen for the first phase of treatment for pulmonary tuberculosis. The experimental regimen will consist of the following: Two months of isoniazid, rifapentine, pyrazinamide and moxifloxacin (HPZM) administered once daily. Pyridoxine (vitamin B6) will be given with each dose of isoniazid. The standard control intensive phase regimen will consist of the following: Two months of isoniazid, rifampin, pyrazinamide, and ethambutol (HRZE) administered once daily. Pyridoxine (vitamin B6) will be given with each dose of isoniazid. Following intensive phase therapy (the study phase), all patients will be treated with a non-experimental continuation phase regimen. In mice, the combination of Moxifloxacin and Rifapentine have cured the animals significantly faster than the standard regimen and this study will be the first step to see if the potential is also there in humans.

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.

Undernutrition at the time of diagnosis of active tuberculosis is a risk factor for increased mortality, and lack of weight gain during anti-tuberculous treatment has been linked to an increased relapse risk. The purpose of this study is to test the effect of Lacprodan® DI-8090 whey protein concentrate on anthropometric measures, treatment outcome and health-related quality of life, against standard practice during anti-tuberculous treatment on patients with a BMI <20 living in Guinea-Bissau.

The study is conducted to compare safety and efficacy of isoniazid administered as an adjusted dose based on NAT2 (arylamine N-acetyltransferase type 2)genotype and as a standard dose. The hypothesis is that the genotype-adjusted dose is superior to the standard dose with regard to hepatotoxicity and early treatment failure, respectively, in the group of slow and rapid acetylators of NAT2.

The objectives of this research are to determine: the burden of intestinal parasitic infections among persons living with pulmonary tuberculosis (TB) whether intestinal parasitic infections alter TB treatment outcomes, including speed of sputum clearance and treatment outcomes the impact of malnutrition on speed of sputum clearance and TB treatment outcomes whether nutritional supplementation improves speed of sputum clearance and treatment outcomes In this study the researchers will investigate how intestinal parasites impact the nutritional status of TB patients before the start of nutritional supplementation and how they alter the trajectory of weight gain in those receiving supplementation by analyzing results from 2 cohorts. LEOPARD Cohort 1- Control-Enroll TB cases, screen for undernutrition, obtain stool for intestinal parasite screening by polymerase chain reaction (PCR), and assess them for treatment outcomes and weight gain TB LION (Learning Impact of Nutrition) - Enroll TB cases, provide nutritional supplementation for 6 months (as part of existing TB LION study), screen for undernutrition, obtain stool for intestinal parasite screening by PCR, and assess them for treatment outcomes and weight gain LEOPARD Cohort 2 - Enroll TB cases, screen for undernutrition, obtain stool for internal parasite screening by PCR, and assess them for treatment outcomes and weight gain.

This is a randomized, double-blind, placebo-controlled, single ascending dose study conducted at one study center in the United States. Four (4) cohorts of 8 subjects each (6 active and 2 placebo). Subjects will participate in only one cohort. Safety will be assessed throughout the study; serial ECGs and serial blood samples will be collected for the safety and PK assessment of sutezolid. Dose escalation to the next cohort (i.e., dose level) will not take place until the Sponsor, in conjunction with the Principal Investigator, has determined that adequate safety, tolerability and PK from the previous cohort has been demonstrated to permit proceeding to the next cohort. Interim PK analyses will be performed for the dose escalation decisions to reconsider the sampling time points as the study progresses. All samples will be sent for analysis and the bioanalytical lab will be unblinded and only run the analysis on active treatment subjects. Data from the analysis used for the escalation meetings will only include active treatment subjects, and will be blinded by subject. Subjects will be housed in the clinic from at least 24 hours prior (from Day -2), until 48 hours (Day 3) after dosing. Subjects will be contacted via a phone call for follow-up questioning about adverse events 7 days later (Study Day 10).

To evaluate the efficacy, safety and tolerability of various doses and durations of linezolid plus bedaquiline and pretomanid after 26 weeks of treatment in participants with either pulmonary XDR-TB, pre-XDR-TB, or treatment intolerant or non-responsive MDR-TB.

A Prospective, Randomized, Open, Active-controlled, Interventional, Exploratory, Phase II Trial of LCB01-0371.
