Brief Summary

This is Double-Blind, Randomized, Placebo-Controlled Phase IIb Clinical Trial to Investigate the Efficacy of RUTI® Therapeutic Vaccination as adjuvant of Tuberculosis chemotherapy. A total of 140 adult TB patients (age > 18 years) with culture confirmed DS-TB (Drug Sensitive) (90 patients) (Cohort A) and MDR-TB (Multi Drug Resistant) (50 patients) (Cohort B) will be enrolled in the study. 25 μg RUTI® vaccine will be given subcutaneously in the deltoid region at the predefined time point (week 1 or month 1 upon start of standard DS- or MDR-TB treatment) respectively. The control group will receive a subcutaneous injection with placebo. The primary and secondary endpoint will be evaluated at the end of intensive phase of treatment however, all patients will be followed up for the whole chemotherapy treatment, i.e. 6 and 24 months for Cohort A and B respectively for exploratory endpoint analysis.
