title: Bivalent rLP2086 Vaccine (Trumenba(®)): A Review in Active Immunization Against Invasive Meningococcal Group B Disease in Individuals Aged 10-25 Years.
abstract: Bivalent rLP2086 vaccine (Trumenba(®)) [hereafter referred to as rLP2086] is a Neisseria meningitidis serogroup B (MenB) vaccine recently licensed in the USA for active immunization to prevent invasive disease caused by MenB in individuals 10-25 years of age. rLP2086, which contains two variants of the meningococcal surface protein factor H-binding protein (fHBP), was approved by the FDA under the accelerated approval pathway after the immunogenicity of the vaccine was demonstrated in several phase II trials. This article reviews the immunogenicity and reactogenicity of rLP2086 as demonstrated in the trials with a focus on the US setting and on use of the vaccine as per FDA-approved labeling. rLP2086 is approved in the USA as a three-dose series administered in a 0-, 2-, and 6-month schedule. In the phase II trials, rLP2086 elicited a robust immune response against a panel of MenB test strains. A strong immune response was evident in a marked proportion of subjects after two vaccine doses, with a further increase after a third dose. The four primary test strains used were selected to be representative of MenB strains prevalent in the USA, with each expressing an fHBP variant heterologous to the vaccine antigens. rLP2086 was generally well tolerated in the trials, with most adverse reactions being mild to moderate in severity. Although some questions remain, including the duration of the protective response, rLP2086 vaccine has the potential to be a valuable tool for the prevention of invasive MenB disease.
