South African Tuberculosis Vaccine Initiative (SATVI) CRS

This trial is in household contacts (HHC) at high risk for developing multidrug resistant tuberculosis (MDR-TB) which is an infection that does not get better with standard treatment for TB. HHC means any person that lives with, has lived with, or shared housekeeping duties in a home or the same place with a person (an Index Case) who has pulmonary MDR-TB (a lung infection or pneumonia with TB) and started treatment for MDR-TB within the past 90 days. It is also for people who have spent more than 4 hours indoors with the index case, during the week before they started MDR-TB treatment.

High-risk household contacts are those with HIV or an immune system problem not from HIV like cancer , latent TB infection (a history of TB infection in the past based on testing), and young children below the age of 5 years.

A5343: A Trial of the Safety, Tolerability, and Pharmacokinetics of Bedaquiline and Delamanid, Alone and in Combination, among Participants Taking Multidrug Treatment for Drug-Resistant Pulmonary Tuberculosis

This is a randomized study, which means, by chance, you will be in one of three groups. You have an equal chance of being assigned to a group like flipping a coin. A5343 is an open label clinical trial, which means you will know which group you are in and what medications you will be taking.

This study will compare three treatment arms for people who have pulmonary multidrug resistant tuberculosis (MDR-TB). Pulmonary MDR-TB is a form of tuberculosis (TB) in the lung that is resistant to two or more of the primary drugs used for the treatment of TB (isoniazid and rifampin).

You will receive standard treatment for MDR-TB plus one or two new drugs for TB, called bedaquiline (BDQ) and delamanid (DLM). Throughout the study, you will be monitored to make sure that there are no safety concerns. Your heart will be monitored closely to make sure it is safe to give the drugs together.
