Official title
TBTC Study 26 PK: Rifapentine Pharmacokinetics in Children Receiving Once Weekly Rifapentine and Isoniazid for the Treatment of Latent Tuberculosis Infection
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Compared to adults, children appear to require higher weight-based doses of rifapentine to acheive comparable drug levels. TBTC Study 26, a study of the effectiveness and tolerability of weekly rifapentine/isoniazid for three months versus daily isoniazid for nine months for the treatment of latent tuberculosis infection, has been amended to include children ages 2-11 based on an initial single-dose study and pharmacokinetic modeling. Study 26PK evaluates the adequacy of the doses chosen for young children enrolled in Study 26 with a single blood draw, 24 hours after the third or subsequent weekly Study 26 dose of rifapentine and isoniazid. An adult control is enrolled for each child enrolled.
