Active clinical trials for "Tuberculosis, Pulmonary"

Pretomanid is being used in an antimicrobial combination regimen(s) to treat patients with pulmonary tuberculosis (TB). The primary purpose of the Male Reproductive Safety - "BPaMZ/SEM"- clinical study is to evaluate the potential effect of pretomanid on human testicular function whilst being used in a 26 weeks antimicrobial combination regimen consisting of bedaquiline (B) plus pretomanid (Pa) plus moxifloxacin (M) and pyrazinamide (Z) (BPaMZ).

This trial is to describe the safety, tolerability and exposure-toxicity relationship of Depazolid given over 16 weeks, in combination with standard-dose Bedaquiline, Delamanid and Moxifloxacin, compared to standard-dose Bedaquiline, Delamanid and Moxifloxacin alone

In a previous randomized control trial, the investigators identified gaps in the implementation of tuberculosis (TB) contact investigation at multiple levels of the service delivery cascade. Drawing on prior experiences, the investigators have recently developed a novel strategy to enhance the implementation of routine contact investigation procedures. This user-centered implementation strategy was created through serial prototyping guided by human-centered design (HCD) and employs communities of practice (CoP) as an adjunctive adaptation and sustainment strategy. The investigators are now conducting a stepped-wedge, cluster-randomized implementation trial in 12 study sites in Uganda to determine if the resulting user-centered implementation strategy enhances the delivery of TB contact investigation and other implementation outcomes, and also improves health outcomes.

endTB-Q Clinical Trial is a Phase III, randomized, controlled, open-label, non-inferiority, multi-country trial evaluating the efficacy and safety of two new, all-oral, shortened regimens for multidrug-resistant tuberculosis (MDR-TB) with fluoroquinolone resistance.

Background: Tuberculosis (TB) is a bacterial lung infection. Typical treatment using anti-TB drugs lasts about 6 months. Some people with less severe TB might not need to take the drugs that long. Researchers think a PET/CT lung scan along with estimating how much TB is in the lungs might show who will be cured after only 4 months of treatment. Objective: To demonstrate that 4 months of treatment is not inferior to 6 months of treatment for people with less severe TB. Eligibility: People 18-75 years old who have TB treatable with standard TB drugs Design: Participants will be screened with: Medical history Physical exam Blood and urine tests HIV test Sputum sample: Participants will be asked to cough sputum into a cup. Chest x-ray Participants will start TB drugs. They will have visits at weeks 1, 2, 4, 8, 12, and about 6 more times during the 18-month study. Visits include: Sputum samples Physical exam Blood tests PET/CT scans at 2-3 visits: Participants fast for about 6 hours before the scan. Participants get FDG, a type of sugar that gives off a small amount of radiation, through an arm vein. They lie on a table in a machine that takes pictures of the body. Chest x-rays at 1-2 visits Participants who we believe are likely to be cured at 4 months will be randomly assigned to get either 6 months of treatment or 4 months of treatment. Participants may be asked to join a substudy using their sputum samples or additional blood tests.

The PRESCIENT trial is a Phase IIc, open-label, randomized trial that will compare a 12-week regimen of bedaquiline (BDQ), clofazimine (CFZ), pyrazinamide (PZA), and delamanid (DLM) with standard treatment for drug-susceptible pulmonary tuberculosis. Eligible participants will be randomized in a 1:1 ratio to BDQ, CFZ, PZA, and DLM (BCZD) or standard anti-TB therapy. Participants in the experimental arm with evidence of poor clinical response at the end of therapy will be re-treated with standard TB therapy. The primary analysis is a superiority efficacy comparison of time to liquid culture conversion through 8 weeks in the experimental (BCZD) arm vs. the standard therapy arm. The other key secondary outcome is safety.

The goal of this clinical trial is to compare the efficacy and safety of a Contezolid and Dlamanid-Containing short regimen to standard longer regimen in Rifampicin-resistant pulmonary tuberculosis (RR-TB). The main question[s] it aims to answer are: Is the efficacy of short regimen better the standard regimen? Is the short regimen safe enough to replace the standard regimen? Participants will: Be given with either short or standard regimen for RR-TB treatment Be asked to complete the scheduled visit as planned.

This study is a clinical trial conducted to determine whether the sitafloxacin-containing three-month regimens are as effective as the standard six-month regimen and the four-month rifapentine and moxifloxacin regimen (substitution of rifapentine for rifampin and moxifloxacin for ethambutol) for treatment of pulmonary tuberculosis. The standard six-month regimen is two months of isoniazid, rifampin, ethambutol, and pyrazinamide, followed by four months of isoniazid and rifampin. The four-month regimen consists of two months of isoniazid, rifapentine, moxifloxacin, and pyrazinamide, followed by two months of isoniazid rifapentine and moxifloxacin. The new three-month tuberculosis treatment regimens are six weeks of isoniazid, rifapentine, Sitafloxacin, and pyrazinamide, followed by seven weeks of isoniazid, rifapentine, and Sitafloxacin, or 13 weeks of isoniazid, rifapentine, Sitafloxacin, and pyrazinamide. The primary research question is to evaluate the efficacy and safety of the 3 month Sitafloxacin-containing regimen, and to determine if it can shorten the treatment of drug-susceptible pulmonary tuberculosis while achieving non-inferiority in treatment success with the current 6 month and 4 month treatment regimens. Safety, side effects of Sitafloxacin for participants in the clinical trial are also assessed. Rates of cure, treatment success, recurrence, and cure (cure without recurrence) are determined for subgroup analysis in the standard six-month regimen group, the four-month regimen group, and two three-month regimen groups.

Tuberculosis (TB) is a global pandemic that despite successful treatment and bacterial eradication can cause chronic ill health, also known as pulmonary impairment after tuberculosis (PIAT). A recent Phase 2b double-blind randomised-controlled clinical trial shows that adjunctive doxycycline therapy along with standard pulmonary TB (PTB) treatment is safe, accelerates resolution of inflammation, suppresses tissue damaging enzyme activity and decreases pulmonary cavity volume (1). The investigators aim to determine if adjunctive doxycycline can reduce PIAT in a fully powered Phase III trial of 8 weeks of adjunctive doxycycline alongside standard pulmonary TB treatment. The investigators hypothesize that doxycycline inhibits tissue destruction in patients with pulmonary tuberculosis (PTB) and thereby leads to improved lung function after treatment. Specific aims To assess for improvement in lung function as measured by forced expiratory volume (FEV1) predicted in PTB patients given doxycycline versus placebo. To investigate whether doxycycline will hasten the resolution of pulmonary cavities measured by CT thorax, suppress inflammatory markers including matrix metalloproteinases and accelerate time to sputum culture conversion. To assess the safety profile of doxycycline with concurrent standard anti-tuberculous treatment.

This study aims to describe the long-term adverse outcomes associated with PTB in children, to describe the evolution of these sequelae, and to determine the epidemiological risk factors associated with these sequelae. The investigators will conduct a prospective cohort study. Children who have completed treatment for PTB will be enrolled. The study visit will be performed in the study clinic, where clinical assessment, spirometry and radiography will be performed. The planned duration of the study is 36 months. Participant enrolment is estimated to begin in March 2022. The estimated date of the last participant enrolled is December 2022.
