Primary Outcome Measures:
  • Number of Subjects With Solicited Local Symptoms [ Time Frame: During the 7-day (Days 0-6) post-vaccination period, following each dose and across doses ]
    Assessed solicited local symptoms included pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 50 millimeters (mm) of injection site. Relationship analysis was not performed.

  • Number of Subjects With Solicited General Symptoms [ Time Frame: During the 7-day (Days 0-6) post-vaccination period, following each dose and across doses ]
    Assessed solicited general symptoms included fatigue, temperature [defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)], gastrointestinal symptoms (gastro) [nausea, vomiting, diarrhoea and/or abdominal pain], headache, malaise and myalgia. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever ≥ 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination.

  • Number of Subjects With Unsolicited Adverse Events (AEs) [ Time Frame: During the 30-day (Days 0-29) post-vaccination period ]
    An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination.

  • Number of Subjects With Serious Adverse Events (SAEs) [ Time Frame: During the entire study period (from Day 0 up to Day 210) ]
    Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

  • Number of Subjects With Different Biochemical and Haematological Levels [ Time Frame: At Day 0 ]
    Among biochemical and haematological parameters assessed were alanine aminotransferase [ALT], aspartate aminotransferase [AST], basophils [BAS], creatinine [CREA], eosinophils [EOS], haematocrit [Hct], haemoglobin [Hgb], lymphocytes [LYM], monocytes [MON], neutrophils [NEU], platelets [PLA], red blood cells [RBC] and white blood cells [WBC]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were- normal, below and above.

  • Number of Subjects With Different Biochemical and Haematological Levels [ Time Frame: At Day 7 ]
    Among biochemical and haematological parameters assessed were alanine aminotransferase [ALT], aspartate aminotransferase [AST], basophils [BAS], creatinine [CREA], eosinophils [EOS], haematocrit [Hct], haemoglobin [Hgb], lymphocytes [LYM], monocytes [MON], neutrophils [NEU], platelets [PLA], red blood cells [RBC] and white blood cells [WBC]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were- normal, below and above.

  • Number of Subjects With Different Biochemical and Haematological Levels [ Time Frame: At Day 30 ]
    Among biochemical and haematological parameters assessed were alanine aminotransferase [ALT], aspartate aminotransferase [AST], basophils [BAS], creatinine [CREA], eosinophils [EOS], haematocrit [Hct], haemoglobin [Hgb], lymphocytes [LYM], monocytes [MON], neutrophils [NEU], platelets [PLA], red blood cells [RBC] and white blood cells [WBC]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were- normal, below and above.

  • Number of Subjects With Different Biochemical and Haematological Levels [ Time Frame: At Day 37 ]
    Among biochemical and haematological parameters assessed were alanine aminotransferase [ALT], aspartate aminotransferase [AST], basophils [BAS], creatinine [CREA], eosinophils [EOS], haematocrit [Hct], haemoglobin [Hgb], lymphocytes [LYM], monocytes [MON], neutrophils [NEU], platelets [PLA], red blood cells [RBC] and white blood cells [WBC]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were- normal, below and above.

  • Number of Subjects With Different Biochemical and Haematological Levels [ Time Frame: At Day 60 ]
    Among biochemical and haematological parameters assessed were alanine aminotransferase [ALT], aspartate aminotransferase [AST], basophils [BAS], creatinine [CREA], eosinophils [EOS], haematocrit [Hct], haemoglobin [Hgb], lymphocytes [LYM], monocytes [MON], neutrophils [NEU], platelets [PLA], red blood cells [RBC] and white blood cells [WBC]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were- normal, below and above.


Secondary Outcome Measures:
  • Frequency of Mycobacterium Tuberculosis Fusion Protein (M72) Specific Cluster of Differentiation 4/8 (CD4/8+) T Cells Expressing at Least Two Different Cytokines [ Time Frame: At Day 0, 30, 60 and 210 ]
    Among cytokines expressed were interleukin-2 [IL-2] and/or interferon-gamma [IFN-γ] and/or tumour necrosis factor-alpha [TNF-α] and/or cluster of differentiation 40-ligand [CD40-L]. Analysis of cytokines expression was done by means of in vitro flow cytometry, using intracellular cytokine staining (ICS).

  • Frequency of M72 Specific CD4/8+ T Cells Expressing at Least One Cytokine and Another Signal Molecule [ Time Frame: At Day 0, 30, 60 and 210 ]

    Expressed cytokine combinations for CD4+ T cells were CD40-L and IL-2 or IFN-γ or TNF-α; IL-2 and CD40-L, or IFN-γ, or TNF-α; IFN-γ and CD40-L, or IL-2, or TNF-α; TNF-α and CD40-L, or IL-2, or IFN-γ.

    For CD8+ T cells no vaccine induced responses were observed, thus results are presented only for the frequency of M72-specific CD8+ T cells expressing at least two cytokines.


  • Anti-M72 Specific Antibody Concentrations [ Time Frame: At Day 0, 30, 60 and 210 ]
    Concentrations given in enzyme-linked immunosorbent assay units per milliliter (EL.U/mL) were expressed as geometric mean concentrations (GMCs).
