Study to Investigate Safety and Tolerability of mRNA-0184 Administered Under Different Infusion Conditions in Healthy Participants

A Phase 1, Randomized, Open-label, Multiple Ascending Dose Study to Investigate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of mRNA-0184 Administered Under Different Infusion Conditions in Healthy Participants

The purpose of this study is to evaluate the safety and tolerability of intravenously (IV) administered mRNA-0184 under different infusion conditions.

Inclusion Criteria:

1. Healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, electrocardiogram (ECG), and vital signs.
2. Participant who could become pregnant must meet conditions as defined in the protocol.

Exclusion Criteria:

1. History of any clinically significant disease or disorder which may either put the participant at risk because of participation in the study or influence the results or the participant's ability to participate in the study.
2. Any clinically significant illness, or medical/surgical procedure, within 4 weeks of the first administration of the study investigational product (IP) (mRNA-0184).
3. Any clinically significant abnormalities in clinical laboratory results at Screening. Repeat assessments are allowed at the Investigator's discretion if a false positive is suspected.
4. Clinically significant abnormal findings in vital signs at Screening.
5. Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody, and human immunodeficiency virus (HIV) antibody.
6. Use of any prescribed medication during the 2 weeks or 5 half-lives of the medication, whichever is longer, prior to the first administration of the study IP. Hormonal contraception is permitted.
7. Has received another IP within 4 weeks of the first dosing of the study IP or within 5 terminal half-lives of the IP, whichever is longer.
