|Condition or disease||Intervention/treatment||Phase|
|Prevention of TB Recurrence||Biological: VPM1002 (Recombinant BCG Vaccine) Other: Placebo||Phase 2 Phase 3|
The study is designed as a multicenter, double-blinded, randomized, placebo-controlled trial with two groups of category 1 pulmonary TB patients who have successfully completed ATT and declared cured by bacteriological confirmation.
The eligible participants will be randomized in 1:1 ratio to receive single dose of either VPM1002 or placebo. After study vaccination, participants will be followed up for one year. Any suspected TB case during follow up will be further evaluated and bacteriologically confirmed. Study participants will be actively followed up for 2 months post-vaccination for any solicited local and regional reaction. SAEs will be recorded and reported throughout study participation.

|Experimental: VPM1002 (Recombinant BCG vaccine)||
Biological: VPM1002 (Recombinant BCG Vaccine)
VPM1002 is a formulated, lyophilized cake of live recombinant Mycobacterium bovis rBCGÄureC::Hly+; VPM1002.
VPM1002 is the active pharmaceutical ingredient. It is a genetically modified BCG vaccine derived from the Mycobacterium bovis BCG subtype Prague characterized as rBCGÄureC::Hly+. Single dose of VPM1002 is administered intradermally.
|Placebo Comparator: Placebo||
Single dose of Placebo is administered intradermally.
- Percentage of bacteriologically confirmed TB recurrence cases [ Time Frame: 2-12 months post-vaccination ]Percentage of TB recurrence patients who have previously been successfully treated for TB, were declared cure and are now diagnosed with a new episode of bacteriologically confirmed recurrent TB after at least 2 months from vaccination.
- Percentage of overall TB recurrence (i.e. either bacteriologically confirmed or clinically diagnosed TB recurrence) [ Time Frame: 2-12 months post-vaccination ]Percentage of TB recurrence patients who have previously been successfully treated by for TB, were declared cure and are now diagnosed with a new episode of either bacteriologically confirmed or clinically diagnosed recurrent TB after at least 2 months from vaccination.
- Safety assessed by Solicited local and regional reactogenicity and Unsolicited adverse events and SAEs [ Time Frame: Throughout study participation i.e.12 months post-vaccination ]
- Solicited local and regional reactogenicity events within 2 months following study vaccination
- Unsolicited adverse events and SAEs throughout the study period
