AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI

Who might be able to join this trial:

  • People who are suspected of having pulmonary tuberculosis (TB in the lungs) AND have had at least one sputum (mucus/phlegm) sample come back positive for TB bacteria — either through a standard smear test or through a specific lab test called Xpert MTB/RIF showing a "medium" or "high" level of bacteria, with no rifampicin resistance detected
  • People who have not yet started any treatment for tuberculosis
  • People aged 12 years or older
  • People who have a verifiable home address that can be visited, and who are willing to let the study team know if their address changes during the study
  • People who have a documented result on file showing their HIV status
  • People who have a documented blood sugar level and diabetes status on file
  • People who are HIV-positive and have a recent immune cell count (CD4 count) of at least 100 cells/mm³, tested within the past 30 days
  • People whose recent blood test results (taken within the past 14 days) meet all of the following: liver enzyme (ALT) levels not too high, bilirubin levels not too high, kidney function (creatinine) within an acceptable range, potassium levels at or above 3.5 meq/L, haemoglobin of at least 7.0 g/dL, and a platelet count of at least 100,000/mm³
  • Women who could become pregnant must have had a negative pregnancy test within the past 7 days
  • People who have given written consent to participate in the study

Who may not be able to join:

  • People who are currently pregnant or breastfeeding
  • People who are unable to swallow or take medications by mouth
  • People who are already receiving treatment for tuberculosis
  • People who weigh less than 40 kg
  • People who have a known allergy or bad reaction to any of the medications used in the study
  • People whose TB bacteria are already known to be resistant to any of these medications: rifampin, isoniazid, pyrazinamide, or ethambutol
  • People with significant other health conditions, including certain heart problems (such as heart failure, coronary heart disease, or irregular heartbeat), cancer, or other serious medical conditions
  • People with a known personal or family history of bleeding disorders
  • People with reduced kidney function, specifically where creatinine clearance is above 1.5 times the upper limit of the normal range (confirm with trial site)
  • People with muscle inflammation (myositis) or a muscle enzyme (creatinine phosphokinase) level more than three times the upper limit of normal
  • People whose overall health situation, in the opinion of the study doctor, means joining the trial would not be in their best interest
  • People who, after joining the study, have sputum samples that never grow TB bacteria across three test points (this would result in removal from the study)
  • People whose TB bacteria are later found to be resistant to isoniazid, rifampin, or fluoroquinolones (a class of antibiotics) — these individuals would be removed from the study after enrolment
