• Uncorrectable electrolytes disorders:

Laborértékek

• Hemoglobin ≤7.9 g/dL;
• Total Calcium <7.0 mg/dL (1.75 mmol/L);
• Potassium <3.0 mEq/L (3.0 mmol/L) or ≥6.0 mEq/L (6.0 mmol/L);

  • Serum creatinine >3 x ULN;
  • Aspartate Aminotransferase (AST) or Alanine Aminotransferase (ALT) ≥3 x ULN;
  • Total bilirubin ≥3 x ULN; Unless otherwise specified, Grade 4 result as defined by the MSF Severity Scale on any of the screening laboratory tests.
  • Has cardiac risk factors defined as:
  • An arithmetic average of the two ECGs with highest QTcF intervals of greater than or equal to 450 ms. Retesting to reassess eligibility will be allowed using an unscheduled visit during the screening phase;
  • Evidence of ventricular pre-excitation (e.g., Wolff Parkinson White syndrome);
  • Electrocardiographic evidence of either:
• Incomplete left bundle branch block or right bundle branch block and QRS complex duration greater than or equal to 120 msec on at least one ECG; • Having a pacemaker implant;
  • Congestive heart failure;
  • Evidence of second or third degree heart block;
  • Bradycardia as defined by sinus rate less than 50 bpm;
  • Personal or family history of Long QT Syndrome;
  • Personal history of arrhythmic cardiac disease, with the exception of sinus arrhythmia;
  • Personal history of syncope (i.e. cardiac syncope not including syncope due to vasovagal or epileptic causes).
  • Concurrent participation in another trial of any medication used or being studied for TB treatment, as defined in cited documents.
  • Is taking any medication that is contraindicated with the medicines in the trial regimen which cannot be stopped (with or without replacement) or requires a wash-out period longer than 2 weeks.

• Has one or more of the following:
• Complete left bundle branch block or right bundle branch block; OR

• Has documented pulmonary tuberculosis due to strains of M. tuberculosis resistant to rifampin (RIF) and not susceptible to fluoroquinolones, according to a validated rapid molecular test. Patients with RIF-resistant TB who are unable to tolerate fluoroquinolones (history of severe adverse events, allergies, hypersensitivity) are also eligible, regardless of resistance/susceptibility to fluoroquinolones;
• Is ≥15 years of age;

• Provides informed consent for study participation; additionally a legal representative of patients considered minor per local laws should also provide consent;
• Lives in a dwelling that can be located by study staff and expects to remain in the area for the duration of the study.
