Summary

This trial aims to find a safe and effective treatment for Tuberculosis Prevention. They want to test different treatment regimens that are shorter and easier for patients to complete than the current standard treatment. The study

Who is the study for?
This trial is for individuals with latent TB or at risk of reactivating a TB infection. Participants should be healthy and able to take daily self-administered medication. The study excludes those who cannot follow the treatment plan, have conditions that might interfere with the drug's effectiveness, or are unable to provide informed consent.
What is being tested?
The trial is testing three different TB preventive treatments: a standard dose of rifampin for four months, a double dose of rifampin for two months, and one month of levofloxacin with rifapentine. It aims to find a regimen under two months long that's as safe and tolerable as the four-month reference treatment.
What are the potential side effects?
Possible side effects include liver issues due to rifampin and tendon damage from levofloxacin. Other common reactions may involve digestive discomfort, skin rashes, or flu-like symptoms.
