Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Weight > 6kg
- Age ≥ 6 months to < 12 years and, in the opinion of the investigator, can tolerate the treatment and study participation.
- Probable or definite TBM according to diagnostic criteria or a positive Gene Xpert cerebrospinal fluid (CSF) test.
- Since participants will all be under legal age of independent consent, a parent or legal guardian must be willing and able to provide informed consent. If the subject is of appropriate age, she/he will also be asked to give assent if developmentally appropriate and clinically possible.
- Participant can comply with the protocol requirements in the opinion of the site investigator.
Exclusion Criteria:
- TB treatment for > 7 days
- Exposure via close contact with someone with multi drug resistant TB (MDR-TB) (or rifampicin mono-resistant TB) or personal history of MDR-TB (or rifampicin mono-resistant TB)
- Known intolerance or allergy to any of the study drugs
- Death imminent and expected within 24 hours, as assessed by the site investigator
- Moderate to severe renal or liver dysfunction (Grade 2 or higher abnormalities of creatinine, alanine aminotransferase (ALT), or direct bilirubin)
- HIV infection with any of the following:
Planned initiation of antiretroviral treatment (ART) during the experimental treatment phase (first 8 weeks), as initiation of ART is contraindicated in that time period with TBM.
On ART with planned continued use of a protease inhibitor or nevirapine (children can be switched to an acceptable alternative regimen and then participate)
- Having participated in other clinical studies with investigational agents or treatments within 8 weeks prior to enrollment.
- A clinically significant active medical condition or the presence of any concomitant severe illness or rapidly deteriorating health condition (outside of TB), which, in the opinion of the site investigator, would prevent appropriate participation in the trial, or that would make implementation of the protocol or interpretation of the study results difficult, or otherwise make the subject a poor candidate for a clinical trial.

Measure Description |
Time Frame |
---|---|---|
Describe neurocognitive outcomes among children ages 6 months to 6 years of age who are treated for TBM, longitudinally over 18 months, by treatmentArm, as measured by the Mullen Gross Motor Scale
Time Frame: 72 weeks
|
The Gross Motor Scale is used to assess infants who are 33 months of age or younger and provides information about the child's kinesthetic experience. Maximum Raw Scores of Gross Motor Scale: 36 Raw scores are converted to T Scores (A type of standardized score) based on the child's age. A T Score has a mean of 50 and a standard deviation of 10. A T Score between 20 and 30 (or less than 20) has a descriptive category of "Very Low" A T Score between 31 and 39 has a descriptive category of "Below Average" A T Score between 40 and 60 has a descriptive category of "Average" A T Score between 61 and 69 has a descriptive category of "Above Average" A T Score between 70 and 80 has a descriptive category of "Very High" |

|
Describe neurocognitive outcomes among children ages 6 months to 6 years of age who are treated for TBM, longitudinally over 18 months, by treatmentArm, as measured by the Mullen Visual Reception Scale
Time Frame: Week 72
|
A cognitive score that may be derived from children ages birth to 68 months of age. The Visual Reception Scale assesses visual processing skills through isolation of oculomotor and visual-motor operations. This scale minimizes the motor output required to execute the response and eliminates the need for verbalized responses. Maximum Raw Scores of the Visual Reception Scale: 50 Raw scores are converted to T Scores (A type of standardized score) based on the child's age. A T Score has a mean of 50 and a standard deviation of 10. A T Score between 20 and 30 (or less than 20) has a descriptive category of "Very Low" A T Score between 31 and 39 has a descriptive category of "Below Average" A T Score between 40 and 60 has a descriptive category of "Average" A T Score between 61 and 69 has a descriptive category of "Above Average" A T Score between 70 and 80 has a descriptive category of "Very High" |
Week 72
|

Time Frame: Week 72
|
A cognitive score that may be derived from children ages birth to 68 months of age. The Fine Motor Scale emphasizes the output aspect of visual organization by assessing visual-motor skills, such as motor planning, motor control, and writing readiness. Maximum Raw Scores of the Fine Motor Scale: 49 Raw scores are converted to T Scores (A type of standardized score) based on the child's age. A T Score has a mean of 50 and a standard deviation of 10. A T Score between 20 and 30 (or less than 20) has a descriptive category of "Very Low" A T Score between 31 and 39 has a descriptive category of "Below Average" A T Score between 40 and 60 has a descriptive category of "Average" A T Score between 61 and 69 has a descriptive category of "Above Average" A T Score between 70 and 80 has a descriptive category of "Very High" |

Time Frame: Week 72
|
A cognitive score that may be derived from children ages birth to 68 months of age. The Receptive Language Scale evaluates the ability to decode verbal input through tasks requiring auditory discrimination, linguistic conceptualization, sequencing, and use of spatial concepts. Maximum Raw Scores of the Fine Motor Scale: 48 Raw scores are converted to T Scores (A type of standardized score) based on the child's age. A T Score has a mean of 50 and a standard deviation of 10. A T Score between 20 and 30 (or less than 20) has a descriptive category of "Very Low" A T Score between 31 and 39 has a descriptive category of "Below Average" A T Score between 40 and 60 has a descriptive category of "Average" A T Score between 61 and 69 has a descriptive category of "Above Average" A T Score between 70 and 80 has a descriptive category of "Very High" |

Time Frame: Week 72
|
A cognitive score that may be derived from children ages birth to 68 months of age. The Expressive Language Scale focuses on the child's use of spoken language for communication and expression during spontaneous utterances and during specific vocal or verbal responses to tasks. Maximum Raw Scores of the Fine Motor Scale: 50 Raw scores are converted to T Scores (A type of standardized score) based on the child's age. A T Score has a mean of 50 and a standard deviation of 10. A T Score between 20 and 30 (or less than 20) has a descriptive category of "Very Low" A T Score between 31 and 39 has a descriptive category of "Below Average" A T Score between 40 and 60 has a descriptive category of "Average" A T Score between 61 and 69 has a descriptive category of "Above Average" A T Score between 70 and 80 has a descriptive category of "Very High" |
