NCT05062759
Brief Summary:
This is a Phase 3b, multicenter, randomized, double-blind, parallel group, placebo-controlled study designed to investigate the potential effect of tezepelumab (210 mg subcutaneous \[SC\] every 4 weeks \[Q4W\]) on antibody responses following seasonal quadrivalent influenza virus vaccination in the fall/winter 2021-2022 in the USA.
Detailed Description:
Participants with moderate to severe asthma will enter the screening period of a minimum of 2 weeks to allow adequate time for all of the eligibility criteria to be evaluated. They will be randomized 1:1 to receive tezepelumab 210 mg or placebo SC Q4W, administered at Weeks 0, 4, 8 and 12. Randomization will be monitored to ensure at least 50% of the randomized participants are between the ages of 12 to 17 years.
Participants will receive a single dose of inactivated quadrivalent seasonal influenza vaccine intramuscularly at Week 12, prior to the fourth dose of study intervention.
Serum samples for evaluation of antibody response will be drawn at Week 12 (pre-vaccination) and at Week 16 (4 weeks post-vaccination) when humoral response to the vaccination is expected to be fully developed.
The End of Treatment (EOT) Visit will be conducted at Week 16 and a final Follow-up Visit and the End of Study Visit will be conducted at Week 28.
