General information about the trial
|
|||
Main objective of the trial |
1. To assess the immunogenicity of 60 microgram (mcg), 120 mcg, and 200 mcg of recombinant lipoprotein 2086 (rLP2086) as measured by serum bactericidal assay (SBA) to meningococcal serogroup B (MnB) strains expressing LP2086 subfamily A and B proteins in healthy infants 1
month after the infant series.
2. To assess the safety and tolerability of 20 mcg, 60 mcg, 120 mcg, and 200 mcg of rLP2086 when given with routine childhood vaccines in healthy infants and toddlers.
|
||
Protection of trial subjects |
The study was in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Conference on Harmonization (ICH) Good Clinical Practice (GCP) Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were followed.

Recruitment
|
|||||||||||||||||||||||||
Recruitment details |
In this study, subjects were to receive rLP2086 vaccine at 2, 4, 6 and 12 months of age. Due to premature termination of study, only single dose of 20 or 60 mcg of rLP2086 vaccine was administered at 2 months and planned treatments of rLP2086 vaccine 120 mcg and 200 mcg were not administered. | ||||||||||||||||||||||||
