Key inclusion & exclusion criteria
Inclusion criteria:

2. Primary residence in the household of the adult MDR-TB index case
3. Consent from the parent or legal guardian for the child for HIV testing (HIV-infected and uninfected children will be included)
4. Consent obtained from the parent or legal guardian for the child to be enrolled

Exclusion criteria:

2. Currently on INH or a FQN (e.g. LFX, MFX, ofloxacin or ciprofloxacin) for =14 days
3. Treated for TB in the previous 12 months
4. Known concurrent exposure to an INH-susceptible (including RIF-monoresistant) index case

Infections and Infestations

TB-CHAMP will compare 24 weeks of daily levofloxacin against 24 weeks of daily placebo. All eligible children within the household will be treated with the same drug (either all levofloxacin or all placebo). Households will be randomised (allocated by chance) to be in either the levofloxacin or placebo group. This allocation is carried out by a computer, and the households have an equal chance of being in either group.

This is a “double blind” study, which means that neither the children (or their family) or the researchers will know whether the tablets each child is taking are levofloxacin or placebo.

Children who participate in the study will undergo approximately ten study visits over two years. Enough tablets will be prescribed for the child to take daily until they are seen at their next clinic visit. Visits will be monthly whilst taking the study drugs, and then every three months. At each visit details of the child’s health, height and weight will be recorded, as well as information about how well they take their medicines and if there are any particular problems taking them. The study tests to be done on the children (investigation for TB, blood tests, etc.) are part of routine recommended clinical care in children exposed to MDR-TB. At some visits some additional blood and urine samples will be collected for storage and future testing.
Primary Outcome(s)

4. TB disease over 96 weeks
5. Incidence of levofloxacin resistant TB disease
