About
This is a phase 2, double-blind, randomized (1:1), placebo-controlled trial with two parallel groups.
H56:IC31 (investigational vaccine)
Placebo
900 HIV-negative adults with a diagnosis of drug susceptible pulmonary TB are planned to be included, recruited from TB clinics with established relationships to the trial sites at the start of their TB treatment.
5 study sites in South Africa: 2 sites from the AURUM institute (Klerksdorp and Tembisa) and 3 in Cape Town at TASK Applied Science (TASK), the University of Cape Town Lung Institute (UCTLI) and South African Tuberculosis Vaccine Initiative (SATVI) under UCT, respectively.
1 study site in Tanzania (TZ): 1 site at Mbeya Medical Research Centre (MMRC) under the National Institute for Medical Research (NIMR).

Preclinical data suggest H56:IC31 may be more efficacious if administered while patients are still on treatment. Following the national guidelines for TB treatment in South Africa and Tanzania, we will obtain sputum samples from patients towards the end of treatment at about the same time they are obtained within the national TB control programmes, and if the sputum is smear negative, the criterion for successful treatment within TB programmes, the individual will be eligible for randomization and vaccination towards the end of their six-month treatment period.
As this is a proof of concept TB vaccine study, HIV positive individuals have been excluded as it is not yet known what effect HIV infection may have on the immune response to the vaccine. However, HIV positive individuals are an important population to include in future studies should efficacy be demonstrated in this study.
