Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The primary objective of this trial is to evaluate the safety and reactogenicity of mRNA-1195 in participants with multiple sclerosis.

Inclusion Criteria	Exclusion Criteria
* Medically stable as determined by Investigator's medical evaluation, which will include assessment of medical history, physical examination, laboratory testing, and review of any previously conducted cardiac monitoring. * Participants who are Epstein-Barr virus (EBV)-seropositive at screening. * Participants who have been previously diagnosed with clinically isolated syndrome, radiologically isolated syndrome, or multiple sclerosis within 24 months of Screening Visit (that is, early in their multiple sclerosis course) and in the opinion of the Investigator have been neurologically stable for at least 30 days prior to Visit 1/Day 1. * A participant who could become pregnant is eligible to participate if they are not pregnant or breast/chest feeding.	* Acutely ill or febrile (temperature ≥38.0 degrees Celsius (℃) \[100.4 Fahrenheit °F\]) within 72 hours prior to or at screening or Day 1. * History of a diagnosis or condition that, in the judgment of the Investigator, is clinically unstable or may affect participant safety, assessment of study endpoints, assessment of immune response, or adherence to study procedures. * Received or plans to receive any non-study vaccine (including authorized or approved vaccines for the prevention of coronavirus disease 2019 \[COVID-19\] regardless of vaccine type) within 28 days before or after the Day 1 study injection, or within 14 days before or after Day 1 study intervention for the influenza vaccine. * Any medical, psychiatric, or occupational condition, including reported history of drug or alcohol abuse, that, in the opinion of the Investigator, might pose additional risk due to participation in the study or could interfere with the interpretation of study results. * Received systemic immunosuppressants within the 30 day period prior to screening (for corticosteroids, ≥10 milligrams (mg)/day of prednisone or equivalent) * Participants with any documented history of myocarditis, pericarditis, or myopericarditis. * Has donated ≥450 milliliter (mL) of blood products within 28 days prior to screening or plans to donate blood products within 28 days post-study injection.
