General information about the trial
|
|||
Main objective of the trial |
The purpose of this study was to describe the safety and reactogenicity of the investigational vaccine.
|
||
Protection of trial subjects |
All subjects were observed closely for at least 60 minutes following the administration of the vaccine, with appropriate medical treatment readily available in case of anaphylaxis. Vaccines were administered by qualified and trained personnel. Vaccine was given only to eligible subjects that had no contraindications to any components of the vaccines. Subjects will be followed up till 13 months after last vaccine administration.

• Because the volumes of the individual blood samples that will be collected were re-distributed after discussion with the central laboratory. The total volume of blood collected per subject across scheduled visits and at AECOPD visits remains similar.
• Because information on processing and storage temperature until shipment was updated for some of the samples after discussion with the central laboratory.
• To clarify that the plasma obtained during PBMC processing will be kept for potential future additional testing.
• To clarify that white blood cell differential count will be done on blood samples for safety assessment.
• In addition, some other, minor clarifications have been made and the list of contributing authors has been updated |

• To add clarification in the tertiary objectives: because acute exacerbations of COPD are complex events, triggered by multiple (interacting) pathogens, assessing the natural immunity to other pathogens might be important for interpretation of the data.
• To add an additional blood sample for haematology assessment at each AECOPD visit. This blood sample will be collected to describe the systemic inflammation at time of exacerbation in terms of white blood cells and differential cell counts.
• To clarify the list of concomitant medication that may lead to elimination of a subject from ATP analysis of immunogenicity (Section 7.6.2): because oral corticosteroids are commonly used in treatment of exacerbations, the administration of oral corticosteroids given for this indication will not fall under the definition of “chronic administration of immunosuppressants or other immune modifying drugs at any time during the study period”, used to determine elimination from the ATP analysis of immunogenicity.
• To add a benefit: risk assessment section (Section 1.3).
• In addition, a typo in the footnote of the table of intervals between visits (Table 9) has been corrected and the list of contributing authors has been updat-ed. |

• In compliance with ICH requirements, the protocol mentions that all results will be presented in an integrated report at the end of the study.
• Following re-development and re-validation of the anti-PD ELISA, a new cut-off was defined.
• Reference to the GSK Biologicals’ Laval laboratory was removed, as this laboratory will not be used in the study. In addition, this laboratory is no longer part of GSK Biologicals’ laboratories.
• Internal assay qualification procedures were revised and it was decided that the level of characterisation of the ELISA assays can be minimal (set-up level) for this study as immunogenicity data are descriptive. In consequence, the assays will be standardized but not qualified as stated in the original version. This change will not impact the validity of the results.
• A tertiary endpoint was added as the presence of viral pathogens in sputum will be examined as part of microbiome analysis.
• In order to see early effects of the vaccine on the microbiome, analysis on fresh sputum samples (culture results) will be done on all available data up to the data lock point of the interim analysis.
• In order to have a first look whether or not the inves-tigational vaccine has an impact on AECOPD, AECOPD analyses will be done up to the data lock point of the interim analysis.
• Wording was added to clarify process for collection of sputum H. influenzae sweeps.
• Wording was updated in order to be aligned with the Statistical Ananlysis Plan.
• In addition, minor edits in other sections were made for clarification purposes. |
