Trial Outcomes & Findings for Study to Assess the Effect of Tezepelumab on the Immune Response to Influenza Vaccination in Participants With Asthma (NCT NCT05062759)
NCT ID: NCT05062759
Last Updated: 2023-06-22
Results Overview
Effect of tezepelumab on the humoral immune response following seasonal influenza virus vaccination in adolescent and young adult participants with moderate to severe asthma was assessed. HAI assay was not performed for H3N2 strain due to the known low haemagglutination effect.
COMPLETED

Participant Flow
This study was conducted in 15 study centres in the United States between 23 August 2021 and 18 July 2022.
The Screening period was 2 to 3 weeks before randomisation. Patients were randomised in a 1:1 ratio to receive tezepelumab or placebo. All the study assessments were performed as per the Schedule of Activities.

PRIMARY outcome
Timeframe: From Week 12 to Week 16Population: Vaccine immunogenicity analysis set consisted of all randomised patients who received the influenza vaccine plus at least 1 dose of tezepelumab or placebo, had pre and post vaccination HAI or Microneutralization antibody measurements, had no influenza infection prior to Visit 7 (Week 16), and had no protocol deviation, judged to have the potential to interfere with the generation or interpretation of an antibody response.
Effect of tezepelumab on the humoral immune response following seasonal influenza virus vaccination in adolescent and young adult participants with moderate to severe asthma was assessed. HAI assay was not performed for H3N2 strain due to the known low haemagglutination effect.

SECONDARY outcome
Timeframe: From Baseline to Week 28Population: Safety analysis set consisted of all patients who received at least 1 dose of study intervention.
Immunogenicity assessments were performed. ADA prevalence was defined as patients who are ADA positive at any time including baseline. Persistently positive was defined as having at least two post-baseline ADA positive measurements (with ≥16 weeks between first and last positive) or an ADA positive result at the last available post-baseline assessment. Transiently positive was defined as having at least one post-baseline ADA positive measurement and not fulfilling the conditions for persistently positive. Treatment boosted ADA was defined as baseline positive ADA titre that was boosted to a 4-fold or higher-level following treatment. Treatment emergent ADA (ADA incidence) was defined as the sum of treatment induced ADA and treatment boosted ADA.
