Are you interested in receiving an experimental vaccine against Norovirus?
This clinical research study is looking at the safety and effectiveness of a vaccine for Norovirus. Norovirus is a very contagious virus that causes vomiting and diarrhea. It is sometimes called the “stomach flu” or the “stomach bug.” However, norovirus illness is not related to the flu. The flu is caused by the influenza virus. Norovirus causes acute gastroenteritis, an inflammation of the stomach or intestines.
The primary objectives of this study are to evaluate the safety and reactogenicity of mRNA-1403, and to demonstrate the efficacy of mRNA-1403 to prevent protocol-defined moderate or severe norovirus acute gastroenteritis (AGE) associated with vaccine matched genotypes.
Would you like to take part?
As a volunteer in a research study, you will receive study-related medical care from the study doctor and regular follow up of your condition to monitor the effectiveness of the care you will receive. The results of this research will be used to find out if the investigational medication being studied will be of benefit to other patients at risk of contracting Norovirus, and whether it will be made widely available in Canada. Study volunteers are an important part of moving medical care forward.
You may qualify to participate in this study if you:
- Understand and are willing and physically able to comply with protocol mandated follow-up, including all procedures as assessed by the Investigator, and who are primarily responsible for their self-care and activities of daily living.
- May have chronic medical diagnoses but should be medically stable as assessed by the following criteria:
- Absence of medical events associated with underlying diagnoses and qualifying as SAEs within 1 month prior to study intervention on Day 1.
- Absence of known, current, and life-limiting diagnoses, which could continue for the duration of the study and which, in the opinion of the Investigator, would make completion of the protocol unlikely.
- Are capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in the protocol.
- Are assigned female at birth, you are eligible to participate if you are not pregnant or breastfeeding/chestfeeding/bodyfeeding and meet protocol defined criteria
You may not qualify to participate in this study if you:
- Are acutely ill or febrile (temperature ≥38.0 degrees Celsius (°C) [100.4 degrees Fahrenheit [°F]) 72 hours prior to or at the Screening Visit or Day 1.
- Have a history of acute gastroenteritis (AGE) within 14 days prior to Day 1 or close contact with an individual with AGE symptoms (in the home, socially, or occupationally) within 14 days prior to Day 1.
- Have a history of a diagnosis or condition that in the judgment of the Investigator, is clinically unstable or may affect participant safety, assessment of safety endpoints, assessment of immune response, or adherence to study procedures.
- Have a current diagnosis of chronic gastrointestinal (GI) disease that is associated with ongoing symptoms of regular vomiting and/or diarrhea. Participants with stable, well-controlled chronic GI disease without regular vomiting and/or diarrhea can be considered for enrollment.
- Have a medical, psychiatric, or occupational condition that may pose additional risk as a result of participation or that could interfere with safety assessments or interpretation of results according to the investigator’s judgment.
- Have undergone surgical procedures within 7 days prior to Day 1 or is scheduled to undergo a surgical procedure within 28 days after study intervention.
- Have a reported history of congenital or acquired immunodeficiency, immunocompromising/immunosuppressive condition, asplenia, or recurrent severe infections per protocol.
- Have a reported history of anaphylaxis, urticaria, or other significant AR requiring medical intervention after receipt of a vaccine or intervention that includes one or more of the same components contained in the study vaccine.
- Have a history of myocarditis, pericarditis, or myopericarditis with onset within 180 days prior to Day 1 whose values have not returned to Baseline clinical status.
- Have a history of Guillain-Barre syndrome.
- Have a reported history of coagulopathy or bleeding disorder considered a contraindication to IM injection or phlebotomy.
- Have any dermatologic conditions that could affect local solicited AR assessments.
- Have diagnosis of malignancy within the previous 2 years (excluding nonmelanoma skin cancer).
- Have received systemic immunosuppressive therapies for >14 days in total within 6 months prior to Day 1 (for corticosteroids ≥10 milligrams (mg)/day of prednisone equivalent) or is anticipating the need for immunosuppressive treatment at any time during participation in the study.
- Have received or plan to receive any licensed vaccine ≤28 days prior to or within 28 days after study intervention (Day 1), except for influenza vaccines, which may be given 14 days before or after receipt of a study intervention.
- Have received systemic immunoglobulins or blood products within 3 months prior to Day 1 or plans for receipt during the study.
- Have donated ≥450 mL of blood products within 28 days prior to Day 1 Visit or plans to donate blood products during the study.
- Have participated in a clinical study with investigational treatment within 90 days prior to Day 1 (Baseline) based on the medical history interview or plans to do so while participating in this study. Participants may continue in prior interventional study follow-up activities, provided that it does not involve further investigational treatment and/or procedures that may affect safety and/or other study endpoints, and study participation does not result in a breach of either study protocol.
There are other eligibility requirements that the study doctor will review. Only the study doctor can finally determine whether you are eligible to participate in the study or not.
