Persons aged =15 years
Absence of HIV-1 infection, as documented by any licensed rapid HIV test or HIV-1 enzyme or chemiluminescence immunoassay (E/CIA) test kit, within 30 days prior to study entry, OR
HIV-1 infection, documented by any licensed rapid HIV test or HIV-1 E/CIA test kit at any time prior to entry and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by HIV-1 antigen or plasma HIV-1 RNA viral load. Two or more HIV-1 RNA viral loads of >1,000 copies/mL are also acceptable as documentation of HIV-1 infection, or documentation of HIV diagnosis in the medical record by a healthcare provider
Documentation within 3 days prior to study entry of stage of disease using BMRC TBM grade:

The following laboratory values obtained within 3 days prior to study entry:
Serum creatinine =1.8 times upper limit of normal (ULN), Hemoglobin =8.0 g/dL for men, =7.5 g/dL for women
Absolute neutrophil count =600/mm3, Platelet count =60,000/mm3, Alanine aminotransferase (ALT) =3 x ULN
Total bilirubin =2 x ULN
For participants of reproductive potential who have not been post-menopausal for at least 24 consecutive months (i.e., no menses within the preceding 24 months), or participants who have not undergone surgical sterilization, hysterectomy, bilateral salpingectomy, bilateral oophorectomy, or tubal ligation, documentation of a pregnancy while receivingstudy treatment and for 30 days after stopping study treatment

Exclusion Criteria

Known current or previous drug resistant TB infection (i.e., resistance to one or more first-line TB medications, including but not limited to INH, RIF, EMB, LZD and PZA)
Known allergy/sensitivity or any hypersensitivity to components of study TB drugs (INH, RIF, LZD, PZA, and EMB) or their formulation
For participants who are able to undergo the Brief Peripheral Neuropathy Screen (BPNS) within 21 days prior to study entry, Grade 3 subjective peripheral neuropathy score on the BPNS AND EITHER vibratory loss OR absent ankle jerks
Expected concomitant use or use up to 21 days prior to study entry of monoamine oxidase inhibitors or selective serotonin reuptake inhibitors, or concomitant use of any other drug with significant interaction with the study drugs (See protocol)
For participants with HIV and ART-naïve, planned initiation of ART during the first 4 weeks after randomization
For participants with HIV and on ART that includes a protease inhibitor, nevirapine, or other prohibited ART (see protocol), contraindication to switching to an acceptable alternative regimen (e.g., efavirenz, high-dose raltegravir or dolutegravir with nucleoside reverse transcriptase inhibitors, as per local SOC) prior to randomization. TB treatment, including study drugs, should be started as soon as possible
Contraindication to LP at discretion of treating clinician (e.g., unequal pressures between intracranial compartments due to mass lesion, non-communicating hydrocephalus)
Positive cryptococcal antigen, gram stain, bacterial culture, or other test result obtained from a CSF specimen collected within 21 days prior to entry as part of routine care indicating CNS infection with a pathogen other than Mtb (e.g., cryptococcal meningitis, bacterial meningitis).
