The investigators want to know if ultra-short, effective treatment for latent tuberculosis (TB) infection (LTBI) could dramatically reduce the global incidence of active TB or not. The investigators hypothesize that short-course (4-week) daily isoniazid/rifapentine (INH/RPT) (1HP) is not inferior to standard -course (12 weeks) INH/RPT weekly regimen (3HP) for the prevention of TB in human immunodeficiency virus (HIV)-infected individuals.

| Eligibility | Inclusion Criteria: 1. Documented HIV-1 infection by standard HIV test or plasma HIV-1 RNA viral load and received ART within 12 months. Participants received ART more than 12 months would be allowed if CD4 cell counts is less than 350 cells/mm3 2. 18 years and older 3. Evidence of latent TB infection, either by TST =5 mm or positive interferon gamma release assay (IGRA) or history of close contact with active pulmonary TB* within 3 months prior entry visit or residing in a high TB burden area** NOTE * close contact is referred to person living/sharing in the same room with active pulmonary TB participants for > 4 hours/day ** high TB burden areas are defined as areas with an estimated or reported TB prevalence of 100 to 300/100,000, according to the WHO. Thailand is included in high TB burden areas. 4. Laboratory values obtained within 30 days prior to entry - Absolute neutrophil count (ANC) >750 cells/mm3 - Hemoglobin >7.4 g/dL - Platelet count >50,000/mm3 - Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) <3x upper limit of normal (ULN) - Total bilirubin <2.5 X ULN 5. Chest radiograph or chest computed tomography (CT) scan without evidence of active tuberculosis, unless one has been performed within 90 days prior to entry. 6. Female participants who are participating in sexual activity that could lead to pregnancy must agree to use one reliable non-hormonal form of contraceptive (i.e., condoms, IUD, diaphragm) during RPT treatment and contraception should be remain to 6 weeks post RPT NOTE Female participants who are not of reproductive potential or whose male partner(s) have undergone successful vasectomy with documented azoospermia or have documented azoospermia are eligible without requiring the use of contraceptives. Participant-reported history is acceptable documentation of menopause, hysterectomy, or bilateral oophorectomy or bilateral tubal ligation. 7. All participants must agree not to participate in a conception process (e.g., active attempt to become pregnant or to impregnate, donate sperm, in vitro fertilization) while receiving RPT and for 6 weeks after stopping this drug. 8. Body weight > 40 kg 9. Ability and willingness of participant to provide informed consent Exclusion Criteria: 1. Treatment for active or latent TB (pulmonary or extrapulmonary) within 2 years prior to study entry or presence of any confirmed or probable active TB at screening. 2. History of Isoniazid (INH) or Rifampicin (RIF)/Rifabutin (RFB) resistant TB at any time prior to study entry or known exposure to INH or RIF/RFB resistant TB (e.g., household member of a person with MDR or XDR TB) at any time prior to study entry. 3. Treatment for >14 consecutive days with a rifamycin or >30 consecutive days with INH at any time during the 2 years prior to enrollment. 4. Current or planned use of protease inhibitor-based ART. 5. Currently on a salvage ART regimen, defined as a regimen started due to confirmed HIV virologic failure on a prior ART regimen or due to known HIV drug resistance. 6. History of liver cirrhosis at any time prior to study entry. 7. Evidence of acute hepatitis, such as abdominal pain, jaundice, dark urine, and/or light stools within 90 days prior to entry. 8. Diagnosis of porphyria at any time prior to study entry. 9. Peripheral neuropathy =Grade 2 according to the Division of AIDS (DAIDS) Toxicity Table, within 90 days prior to study entry. 10. Known allergy/sensitivity or any hypersensitivity to components of study drug(s) or their formulation. 11. Active drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements. 12. Acute or serious illness requiring systemic treatment and/or hospitalization within 30 days prior to entry. 13. Pregnancy or breastfeeding |
