A Phase 2, Randomized, Active-controlled, Observer-blinded Trial, To Assess The Safety, Tolerability, And Immunogenicity Of Mcv4, Tdap Vaccine And Bivalent Rlp2086 Vaccine When Administered Concomitantly In Healthy Subjects Aged > = 10 To <13 Years

In Brief

A Phase 2 clinical trial evaluating rLP2086 + MCV4 + Tdap, MCV4 + Tdap + saline, and 1 other intervention for Vaccines and Meningococcal Vaccines. Completed, enrolled 2,648 participants across 117 sites.

Detailed Summary

This is a clinical study to assess the safety, tolerance and immunogenic response to MCV4(quadrivalent meningococcal polysaccharide conjugate, meningococcal serogroups A,C,Y, and W135), Tdap (diphtheria, tetanus, and acellular pertussis), and bivalent rLP2086 vaccine. Healthy male and female subjects, between the ages of 10 to 12 years old, will be randomized into 1 of 3 groups. The subjects, investigators, site staff and sponsor will be blinded to all injections given throughout the study. An unblinded administrator will be responsible to administer the vaccinations to all subjects and will be unblinded to the subject randomization in order to determine which subjects were in randomized to group 3 so they may receive their catch-up vaccinations of MCV4 and Tdap. A final telephone contact will be conducted with all subjects 6-months post their last vaccination to obtain safety information.

Interventions

rLP2086 + MCV4 + Tdapbiological

At visit 1, group 1 will receive MCV4 + Tdap vaccines concomitantly with an injection of rLP2086. At visits 3 and 5 (Months 2 and 6), group 1 will receive an injection of rLP2086.

MCV4 + Tdap + salinebiological

At visit 1, group 2 will receive MCV4 + Tdap vaccines concomitantly with an injection of saline. At visits 3 and 5 (months 2 and 6), this group will receive a saline injection only.

rLP2086 + salinebiological

At visit 1, group 3 will receive 2 injections of saline concomitantly with an injection of rLP2086. At visits 3 and 5 (Months 2 and 6), group 3 will receive an injection of rLP2086. Subjects randomized to this group will receive MCV4 and Tdap following their final visit blood draw (Visit 6).
