Study Endpoints

Primary Endpoints

Anti-Protein D (PD), Anti-Protein E (PE), Anti-type IV Pili Subunit (PilA) and Anti-ubiquitous Surface Protein A2 of Moraxella Catarrhalis (UspA2) Adjusted Geometric Mean Concentrations (GMCs), One-month Post Dose-2 of NTHi-Mcat Vaccine
At 1 month after dose 2 of NTHi-Mcat vaccine (Day 181, in Sh_NTHi-Mcat_1 group and Day 91 in NTHi-Mcat group)

Antibody concentrations as measured by ELISA (Enzyme-linked immunosorbent assay) and expressed as adjusted (ANCOVA model) GMCs in ELISA units per milliliter (EU/mL). Cut-off value for the assay is 153, 16, 8 and 28 EU/mL for Anti-PD, Anti-PE, Anti-PilA and Anti-UspA2 antibodies respectively. The ANCOVA model includes study group, smoking status (current or former), age category (50-59, 60-69, 70-80 years of age) and center as factors and the antibody concentration before Dose 1 as covariate. As per protocol set (PPS) sample size was not met in Sh\_NTHi\_Mcat\_3 and Sh\_NTHi-Mcat\_6 groups then timeframe was adapted as follows: At 1 month after dose 2 of NTHi-Mcat vaccine (Day 181 in Sh\_NTHi-Mcat\_1 group and Day 91 in NTHi-Mcat group)

Secondary Endpoints

Anti-PD, Anti-PE, Anti-PilA, Anti-UspA2 Antibody Concentrations in Terms of GMCs, Before First NTHi-Mcat Vaccine
Before the first dose of NTHi-Mcat vaccine (Day 91, Day 151 and Day 241 for Sh_NTHi-Mcat_1, Sh_NTHi-Mcat_3 and Sh_NTHi-Mcat_6 group, respectively, and Day 1 for NTHi-Mcat group)
Anti-PD, Anti-PE, Anti-PilA, Anti-UspA2 Antibody Concentrations in Terms of GMCs, One-month Post Dose-2 of NTHi-Mcat Vaccine
At one month after the second dose of NTHi-Mcat vaccine (Day 181, 241, 331 in the Sh_NTHi-Mcat_1, Sh_NTHi-Mcat_3 and Sh_NTHi-Mcat_6 group, respectively, and Day 91 in the NTHi-Mcat group)
Percentage of Seropositive Subjects for Anti-PD, Anti-PE, Anti-PilA, Anti-UspA2 Antibodies Before First NTHi-Mcat Vaccine
Before the first dose of NTHi-Mcat vaccine (Day 91, Day 151 and Day 241 in the Sh_NTHi-Mcat_1, Sh_NTHi-Mcat_3 and Sh_NTHi-Mcat_6 group, respectively, and Day 1 in the NTHi-Mcat group)

ArmTypeDescription
Sh_NTHi-Mcat_1 GroupEXPERIMENTALSubjects enrolled in this group received 2 doses of GSK Biologicals' Shingrix vaccine at Day 1 and Day 61, and following a 1-month gap, subjects received 2 doses of GSK Biological's NTHi-Mcat investigational vaccine 2 months apart, at Day 91, and Day 151.
Sh_NTHi-Mcat_3 GroupEXPERIMENTALSubjects enrolled in this group received 2 doses of GSK Biologicals' Shingrix vaccine at Day 1 and Day 61 and, following a 3-month gap, subjects received 2 doses of GSK Biological's NTHi-Mcat investigational vaccine 2 months apart, at Day 151 and Day 211.
Sh_NTHi-Mcat_6 GroupEXPERIMENTALSubjects enrolled in this group received 2 doses of GSK Biologicals' Shingrix vaccine at Day 1 and Day 61 and, following a 6-month gap, subjects received 2 doses of GSK Biological's NTHi-Mcat investigational vaccine 2 months apart at Day 241 and Day 301.
NTHi-Mcat GroupACTIVE_COMPARATORSubjects enrolled in this group received 2 doses of GSK Biological's NTHi-Mcat investigational vaccine 2 months apart, at Day 1 and Day 61.
Shingrix-Only GroupEXPERIMENTALSubjects belonging to this group were originally randomized to either Sh\_NTHi-Mcat\_1 Group, Sh\_NTHi-Mcat\_3 Group or Sh\_NTHi-Mcat\_6 Group, they received at least 1, maximum 2 doses of GSK Biologicals Shingrix vaccine at Day 1 and Day 61, but didnt receive any dose of NTHI Mcat investigational vaccine. Only safety data were collected for these subjects.
