Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Geometric Mean Titer (GMT) of Anti-Hemagglutinin (HA) Antibodies at Day 29, as Measured by Hemagglutination Inhibition (HAI) Assay | Day 29 | |
| Primary | Number of Participants Reaching Seroconversion at Day 29 as Measured by HAI Assay | Day 29 | Seroconversion is defined as a Day 29 titer ≥1:40 if baseline is \<1:10 or a 4-fold or greater rise if baseline is ≥1:10 in anti-HA antibodies measured by HAI assay. |
| Primary | Number of Participants with an HAI Titer ≥1:40 at Day 29 | Day 29 | |
| Primary | Geometric Mean Fold Rise (GMFR), as Measured by HAI Assay | Baseline to Day 29 | |
| Secondary | Number of Participants with Unsolicited Adverse Events (AEs) | Day 1 through Day 29 | |
| Secondary | Number of Participants with Serious AEs, Medical-attended AEs and AE of Interest, and AEs Leading to Discontinuation | Day 1 through Day 29 |
