Title: TBTC Study 28: Evaluation of a Moxifloxacin-based, Isoniazid-sparing Regimen for Tuberculosis Treatment
Brief Summary: This double-blind, randomized controlled trial evaluates moxifloxacin versus isoniazid in daily treatment during the first two months of treatment with rifampin, pyrazinamide and ethambutol for sputum smear-positive pulmonary tuberculosis.


Options:
A: Inclusion Criteria:

* Male or female patients
* Aged 18 to 65 years
* Currently suffering from recently diagnosed microscopically proven pulmonary tuberculosis and providing informed consent for inclusion in the study.

Exclusion Criteria:

* Patients with history of tuberculosis treatment within the last 3 years
* History of diabetes mellitus or non insulin dependent diabetes mellitus requiring treatment
* Concomitant infection requiring additional anti-infective treatment (especially anti-retroviral therapy)
* HIV infected patients with WHO stage 3 infection - except those presenting with only the "loss of weight\>10% body weight" criterion - and all HIV infected patients at WHO stage 4.
B: Inclusion Criteria:

* Suspected pulmonary tuberculosis with acid-fast bacilli in a stained smear of expectorated or induced sputum. Patients whose sputum cultures do not grow M. tuberculosis and those having an M. tuberculosis isolate resistant to (one or more) isoniazid, rifampin, fluoroquinolones, will be discontinued from the study, but followed for 14 days to detect late toxicities from study therapy. Patients having extra-pulmonary manifestations of tuberculosis, in addition to smear-positive pulmonary disease, are eligible for enrollment. Sputum must be expectorated or induced; smear results from respiratory secretions obtained by bronchoalveolar lavage or bronchial wash may not be used for assessment of study eligibility.
* Willingness to have HIV testing performed, if HIV serostatus is not known or if the last documented negative HIV test was more than 6 months prior to enrollment. HIV testing does not need to be repeated if there is written documentation of a positive test (positive ELISA and Western Blot or a plasma HIV-RNA level greater than 5000 copies/ml) at any time in the past.
* 7 (seven) or fewer days of multidrug therapy for tuberculosis disease in the 6 months preceding enrollment.
* 7 (seven) or fewer days of fluoroquinolone therapy in the 3 months preceding enrollment.
* Age \> 18 years
* Karnofsky score of at least 60 (requires occasional assistance but is able to care for most of his/her needs; see Appendix B).
* Signed informed consent
* Women with child-bearing potential must agree to practice an adequate (barrier) method of birth control or to abstain from heterosexual intercourse during study therapy.
* Laboratory parameters done at, or \<14 days prior to, screening:
* Serum amino aspartate transferase (AST) activity ≤ 3 times the upper limit of normal
* Serum total bilirubin level ≤ 2.5 times the upper limit of normal
* Serum creatinine level ≤ 2 times the upper limit of normal
* Complete blood count with hemoglobin level of at least 7.0 g/dL
* Complete blood count with platelet count of at least 50,000/mm3
* Serum potassium \> 3.5 meq/L
* Negative pregnancy test (women of childbearing potential)

Exclusion Criteria:

* Breast-feeding
* Known intolerance to any of the study drugs
* Known allergy to any fluoroquinolone antibiotic
* Concomitant disorders or conditions for which moxifloxacin (MXF), isoniazid (INH), rifampin (RIF), pyrazinamide (PZA), or ethambutol (EMB) are contraindicated. These include severe hepatic damage, acute liver disease of any cause, and acute uncontrolled gouty arthritis.
* Current or planned therapy during the intensive phase of therapy using drugs having unacceptable interactions with rifampin (rifabutin can be substituted for rifampin during the continuation phase of therapy).
* Current or planned antiretroviral therapy during the intensive phase of therapy.
* History of prolonged QT syndrome or current or planned therapy with quinidine, procainamide, amiodarone, sotalol, disopyramide, ziprasidone, or terfenadine during the intensive phase of therapy.
* Pulmonary silicosis
* Central nervous system TB
C: Inclusion Criteria:

1. Provide written, informed consent prior to all trial-related procedures including HIV testing.
2. Male or female, aged between 18 and 65 years inclusive.
3. Body weight (in light clothing and with no shoes) between 40 and 90 kg, inclusive.
4. Newly diagnosed, previously untreated, sputum smear-positive pulmonary TB.
5. A chest X-ray picture which in the opinion of the Investigator is compatible with TB.
6. Sputum positive on direct microscopy for acid-fast bacilli (at least 1+ on the IUATLD/WHO scale).
7. Ability to produce an adequate volume of sputum as estimated from a spot assessment (estimated 10 ml or more overnight production).
8. Females may participate if they are: 1) of non-childbearing potential (have had a bilateral oophorectomy and/or hysterectomy or have been postmenopausal for at least 12 consecutive months), 2) if they are using effective birth control methods and are willing to continue practicing birth control methods throughout treatment or 3) be non-heterosexually active, practice sexual abstinence or have a vasectomized partner (confirmed sterile). Therefore to be eligible for this study women of childbearing potential should either: 1) use a double barrier method to prevent pregnancy (i.e. use a condom with either diaphragm or cervical cap) or 2) use hormonal based contraceptives in combination with a barrier contraceptive, or 3) use an intrauterine device in combination with a barrier contraceptive. They must also be willing to continue these contraceptive measures until 6 months after the last dose of study medication or 6 months after discontinuation from study medication in case of premature discontinuation. (Note: Hormone-based contraception alone may not be reliable when taking IMP; therefore, hormone-based contraceptives alone cannot be used by female participants to prevent pregnancy).
9. Male participants who are having heterosexual intercourse with females of child-bearing potential are required to use one of the following birth control methods during their participation in the trial and for 12 weeks after their last dose of study medication to prevent pregnancy:

   * a double barrier method which can include a male condom, diaphragm, cervical cap, or female condom; or
   * a barrier method combined with hormone-based contraceptives or an intra-uterine device for the female partner.

The use of the above mentioned birth control method does not apply if the male participant has been vasectomised or has had a bilateral orchidectomy minimally one month prior to screening, or is not heterosexually active, or practice sexual abstinence or if the female sexual partner has had a bilateral oophorectomy and/or hysterectomy or has been postmenopausal for at least 12 consecutive months.
