NCT05827068

Brief Summary

The purpose of this study is to measure the safety and the immune response to 3 next-generation influenza vaccine candidates (mRNA-1011.1, mRNA-1011.2, and mRNA-1012.1) compared with influenza vaccine candidate mRNA-1010 controls in healthy adult participants.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants With Solicited Local and Systemic Adverse Reactions (ARs)

    Solicited ARs (local and systemic) were collected in an electronic diary (eDiary). Local ARs included: injection site pain, injection site erythema (redness), injection site swelling/induration (hardness), and axillary (underarm) swelling or tenderness ipsilateral to the side of injection. Systemic ARs included: fever, headache, fatigue, myalgia, arthralgia, nausea/vomiting, and chills. All solicited ARs considered causally related to injection were graded 0-4 (per Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials); lower score indicates lower severity, and a higher score indicates greater severity.

    7 days post-vaccination

  • Number of Participants With Unsolicited AEs

    An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. Any abnormal laboratory test result (hematology, clinical chemistry, or prothrombin time \[PT\]/partial thromboplastin time \[PTT\]) or other safety assessment (for example, electrocardiogram, radiological scan, vital sign measurement), including one that worsened from baseline and was considered clinically significant in the medical and scientific judgment of the Investigator was recorded as an AE. Number of participants with unsolicited AEs (SAEs and non-serious AEs) up to 28 days post-vaccination are reported in this outcome measure.

    Up to 28 days post-vaccination

  • Number of Participants With SAEs, AEs of Special Interest (AESIs), Medically Attended AEs (MAAEs), and AEs Leading to Discontinuation

    An SAE was defined as any AE that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in disability/permanent damage, was a congenital anomaly/birth defect, or was an important medical event. AESIs included thrombocytopenia, new onset of or worsening of the protocol specified neurologic diseases, anaphylaxis, and myocarditis/pericarditis. An MAAE is an AE that lead to an unscheduled visit to an healthcare practitioner. This included visits to a study site for unscheduled assessments (for example, abnormal laboratory follow-up) and visits to healthcare practitioners external to the study site (for example, urgent care, primary care physician). Number of participants with SAEs, AESIs, MAAEs, and AEs leading to discontinuation up to the end of study (Day 181) are reported in this outcome measure.

    Day 1 to Day 181 (end of study [EOS])

Secondary Outcomes (3)

  • Geometric Mean Titer (GMT) of Anti-Hemagglutinin (HA) Antibodies at Day 29, as Measured by Hemagglutination Inhibition (HAI) Assay for Vaccine-matched Influenza A and B Strains

    Day 29

  • Geometric Mean Fold Rise (GMFR) of Anti-HA Antibodies at Day 29, as Measured by HAI Assay for Vaccine-matched Influenza A and B Strains

    Baseline, Day 29

  • Percentage of Participants Reaching Seroconversion at Day 29, as Measured by HAI Assay for Vaccine-matched Influenza A and B Strains
