South African Tuberculosis Vaccine Initiative (SATVI) CRS

A5406 is a study for people with pulmonary drug-sensitive (DS) tuberculosis (TB) without evidence of resistance to the TB drugs isoniazid (INH) or rifampin (RIF) and with HIV. All participants will receive anti-TB treatment (2HPZM: 8 weeks of rifapentine [RPT]-moxifloxacin [MOX] plus INH and pyrazinamide, then 2HPM: 9 weeks of RPT-MOX plus INH). Dolutegravir (DTG)-based anti-HIV therapy (ART) will be taken from week 6 until the end of the study (week 48), with a double-dose of DTG for the first 12 weeks.

A5409: A Phase 2 Randomized, Adaptive, Dose-Ranging, Open-Label Trial of Novel Regimens for the Treatment of Pulmonary Tuberculosis (RAD-TB)

The standard of care (SOC) treatment of tuberculosis (TB) was developed over 40 years ago, and the treatment is long (6 months) and hard. In many settings, the medicine does not work well because people stop taking it or miss doses, which leads to TB returning. For some people, the SOC treatment can cause negative side effects.

This study will evaluate new medication regimens for the treatment of TB. This study is adaptive, which means, as new medication regimens are identified for the treatment of TB, some of them will be selected for testing in this study. Therefore, there may be different drug regimens being used as part of the study at different times.

A5300B/I2003B: Protecting Households On Exposure to Newly Diagnosed Index Multidrug-Resistant Tuberculosis Patients (PHOENIx MDR-TB)

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.
