Title: A Phase II, Placebo-controlled, Double-blind, Randomized Trial to Evaluate the Anti-bacterial Activity, Safety, and Tolerability of TMC207 in Subjects With Newly Diagnosed Sputum Smear-positive Pulmonary Infection With Multi-drug Resistant Mycobacterium Tuberculosis (MDR-TB).
Brief Summary: The objective of this study is to demonstrate that the antibacterial activity of TMC207 is better than placebo when added to a standardized Background Regimen (BR) for treatment of multi-drug resistant TB. Also safety and tolerability will be evaluated.


Options:
A: Inclusion Criteria:

* Provide written, informed consent prior to all trial-related procedures including HIV testing (if an HIV test was performed within 1 month prior to trial start, it should not be repeated as long as documentation can be provided \[ELISA and/or Western Blot\]).
* Body weight (in light clothing and with no shoes) between 40 and 90 kg, inclusive.
* Sputum smear-positive pulmonary TB (at trial appointed laboratory). For Drug Sensitive TB treatment arms, subjects should be newly diagnosed and previously untreated. Exception: Participants can be included in the trial if they were diagnosed and treated for TB greater than 5 years prior to screening and can provide documentation of cure for that episode. Additionally, participants who have previously received H prophylactically can be included as long as that treatment is/was discontinued at least 7 days prior to randomization into this trial. Drug sensitive status to be confirmed with fluoroquinolone, rifampicin and isoniazid susceptibility testing at screening using Hain Plus rapid sputum test.

For the MDR-TB treatment arm only: Subjects with smear-positive MDR infection, defined as confirmed resistance to at least both R and H confirmed at screening for entry into this trial. Resistance to R and H will be determined using the rapid screen test (Hain Plus). If the first spot sputum shows an indeterminate result, the test must be repeated on freshly collected spot sputum or overnight sputum and that result may be used.

Subjects with newly diagnosed MDR-TB are defined as a) subjects with MDR-TB who have never been treated for TB before, or b) subjects with MDR-TB who have previously been treated with only one course of first-line TB drugs (H, R, E, Z and/or S) and that treatment is/was discontinued at least 7 days prior to randomization into this trial. Additionally, MDR-TB participants who have previously received H prophylactically can be included as long as that treatment is/was discontinued at least 7 days prior to randomization into this trial.

* A chest X-ray picture which in the opinion of the Investigator is compatible with TB.
* Sputum positive (at site laboratory) on direct microscopy for acid-fast bacilli (at least 1+ on the IUATLD/WHO scale).
* Ability to produce an adequate volume of sputum as estimated from a spot assessment (estimated 10 ml or more overnight production).
* Females may participate if they are: 1) of non-childbearing potential (have had a bilateral oophorectomy, tubal ligation 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 one week after the last dose of study medication or one week 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).
* 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 three months prior to screening, or is not heterosexually active, or practices sexual abstinence or if the female sexual partner has had a bilateral oophorectomy, tubal ligation and/or hysterectomy or has been postmenopausal for at least 12 consecutive months.

Exclusion Criteria:

* Resistance to fluoroquinolones (Hain plus rapid test) and/or pyrazinamide. Participants may be included in the study prior to receipt of the susceptibility test results for fluoroquinolones or pyrazinamide, however once these are received after a participant has entered into the study and if the results show the participant is resistant to fluoroquinolones and/or pyrazinamide, such a participant should be removed from the trial. DS participants will not be replaced, but MDR-TB participants taking part in the EBA Sub-Study could be replaced after consultation and written approval with the sponsor.
