A Dose Escalation Study to Evaluate Safety, Reactogenicity, and Immunogenicity of mRNA-1345 in Healthy Adults and in Children Who Are Respiratory Syncytial Virus Seropositive
Study Purpose
The primary objectives of this study are to evaluate the tolerability and reactogenicity of a single injection of 1 of 3 dose levels of mRNA-1345 in younger adults; of 3 injections of the middle dose level of mRNA-1345 given 56 days apart in younger adults; of a booster injection of mRNA-1345 given approximately 12 months after the primary injection in older adults; and of 3 injections of 1 of 2 dose levels of mRNA-1345 given 56 days apart in children who are RSV-seropositive.

Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
