ExclusionCriteria |
Details |
i. Any chronic febrile illness with oral temperature > 100°F on the day of randomization.
ii. Prior or present anti-TB treatment
iii. Any laboratory abnormalities (haematological and biochemical), at the time of screening, which is of clinical significance as determined by the Investigator.
iv. Pregnant and / or lactating female participants.
v. Presence of any illness requiring short hospital referral (temporary exclusion).
vi. Reactive serology for HIV.
vii. Any confirmed or suspected immunodeficient condition based on medical history and physical examination and a family history of congenital or hereditary immunodeficiency.
viii. History of chronic renal failure/dialysis, silicosis, gastrectomy, jejunoileal bypass, solid organ transplantation such as renal or cardiac transplants, carcinoma of the head and neck, and disorders of the liver, kidney, lung, heart, or nervous system, or other metabolic inflammatory conditions, psychiatric, occupational problems that make it unlikely the volunteer will comply with the protocol as determined by the local investigator.
ix. History of previous administration of experimental MTB vaccines.
x. History of administration of any immunoglobulins, any immunotherapy (antineoplastic chemotherapy, radiation therapy, immunosuppressants to induce tolerance to transplants, and corticosteroids use) and/or any blood products within the 3 months preceding study vaccination, or planned future administrations during the study period. Participants on inhaled/topical steroids may be permitted to participate in the study.
xi. Participation in any clinical trial within 3 months prior to and/or planned concurrent participation in another interventional clinical trial at any point throughout the entire timeframe for this study.
xii. History of allergic reactions or anaphylaxis to any vaccine or component of the vaccine.
xiii. Presence of any severe systemic/autoimmune disorders as determined by medical history and / or physical examination/ or lab investigations at the time of screening, which in the judgment of the Investigator would compromise the participant’s health or is likely to result in nonconformance to the protocol or a participant’s ability to give written informed consent/assent.

Brief Summary
|
This is a a Phase III, Randomized, Double-blind, Placebo controlled Trial to Evaluate the Efficacy and Safety of VPM1002 and Immuvac Vaccines in Preventing Tuberculosis (TB) in Healthy Household Contacts of Newly Diagnosed Sputum Positive Pulmonary TB Patients, sponsored by ITRC, ICMR. Approximately12000 healthy household contacts of newly diagnosed PTB patients at six states (sites and sub-sites) in India. The primary objective of the study is to evaluate the efficacy of VPM1002 and Immuvac by comparing the reduction in incidence of TB over 3-year period among Indian healthy household contacts of newly diagnosed sputum positive PTB patients vaccinated with VPM1002 and Immuvac in comparison to placebo. The secondary objectives include to evaluate the efficacy of VPM1002 and Immuvac in prevention of LTBI in healthy household contacts of newly diagnosed sputum positive PTB patients in comparison to placebo [at 3 sites]; to evaluate the safety of VPM1002 and Immuvac in Indian healthy household contacts; and to evaluate the Immunogenicity of VPM1002 and Immuvac in healthy household contacts as compared to placebo against tuberculosis [at 3 sites]. Interim analysis will be done at the time when 80 incident TB cases are observed in the trial or 50% of recruitment is completed, whichever is earlier. Final analysis will be done at the time when 160 incident TB cases are observed in the trial or end of follow up period whichever is earlier. |
