Study Details

Study Description

Brief Summary

The study will describe the safety, tolerability, and immunogenicity of up to 6 RSV vaccine formulations when administered alone or concomitantly with seasonal inactivated influenza vaccine (SIIV).

Condition or Disease	Intervention/Treatment	Phase
Respiratory Tract Infections	Biological: Formulation A; Biological: Formulation B; Biological: Placebo	Phase 2

Detailed Description

The study will describe the safety, tolerability, and immunogenicity of up to 6 RSV vaccine formulations when administered alone or concomitantly with SIIV. Healthy male and female subjects divided into 2 age groups (18-49 years of age and 50-85 years of age in the sentinel cohort and 18-49 years of age and 65-85 years of age in the expanded cohort) will be enrolled. Age groups will run in parallel. Subjects in the sentinel cohort in each age group will receive one of two RSV vaccine formulations at one of 3 antigen dose levels or placebo. Subjects in the expanded cohort in each age group will receive one of two RSV vaccine formulations at one of 3 antigen dose levels with and without SIIV.

7. Primary Outcome

Title	Expanded Cohort: Percentage of Participants (Aged 18 to 49 Years) With Systemic Reactions Within 14 Days After Vaccination 1
Description	Systemic reactions: fever, fatigue/tiredness, headache, nausea, muscle pain, joint pain, vomiting, diarrhea and any systemic event recorded by participants in an e-diary. Fever: >= 38.0 deg C, mild (>=38.0 to 38.4 deg C, >38.4 to 38.9 deg C), moderate (>38.9 to 40.0 deg C and >40.0 deg C), severe (>38.9 deg C to 40.0 deg C) and grade 4 (>40.0 deg C). Fatigue, headache, nausea, muscle pain and joint pain were graded as mild: did not interfere with activity, moderate: some interference with activity and severe: prevented daily routine activity. Vomiting was graded as mild: 1 to 2 times in 24 h, moderate: >2 times in 24h and severe: requires intravenous hydration. Diarrhea was graded as mild: 2 to 3 loose stools in 24h, moderate: 4 to 5 loose stools in 24h and severe: 6 or more loose stools in 24h.
Time Frame	Within 14 days after vaccination 1 on Day 1
