About this study
Official title: A Multicenter Phase II/III Double-Blind, Randomized, Placebo Controlled Study To Evaluate The Efficacy And Safety Of VPM1002 In The Prevention Of Tuberculosis (TB) Recurrence In Pulmonary TB Patients After Successful TB Treatment
This is a Phase II/III trial with two groups of adults successfully cured of category 1 pulmonary TB receiving either VPM1002 or placebo. Single dose of VPM1002 / placebo will be administered to calculate efficacy of the vaccine against TB recurrence.
Read the detailed description
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.

VPM1002 (Recombinant BCG Vaccine)Biological
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.
PlaceboOther
Single dose of Placebo is administered intradermally.

| VPM1002 (Recombinant BCG vaccine) | Experimental | Not described Receives: Biological: VPM1002 (Recombinant BCG Vaccine) |
| Placebo | Placebo comparator | Not described Receives: Other: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of bacteriologically confirmed TB recurrence cases
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.
Measured: 2-12 months post-vaccination
Secondary outcomes (2)
Percentage of overall TB recurrence (i.e. either bacteriologically confirmed or clinically diagnosed TB recurrence)
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.
Measured: 2-12 months post-vaccination
Safety assessed by Solicited local and regional reactogenicity and Unsolicited adverse events and SAEs
- Solicited local and regional reactogenicity events within 2 months following study vaccination
- Unsolicited adverse events and SAEs throughout the study period
Measured: Throughout study participation i.e.12 months post-vaccination

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing VPM1002 (Recombinant BCG Vaccine) in people with Prevention of TB Recurrence, run by Serum Institute of India Pvt. Ltd. at 10 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 sites in India, Bangladesh. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of bacteriologically confirmed TB recurrence cases (time frame: 2-12 months post-vaccination). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03152903, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2025; AzTrials last refreshed its copy on 6 Nov 2026.
