Descriptive Information
Brief Title  ICMJE A Study to Evaluate the Safety, Reactogenicity, and Effectiveness of mRNA-1273 Vaccine in Adolescents 12 to <18 Years Old to Prevent COVID-19
Official Title  ICMJE A Phase 2/3, Randomized, Observer-Blind, Placebo Controlled Study to Evaluate the Safety, Reactogenicity, and Effectiveness of mRNA-1273 SARS CoV 2 Vaccine in Healthy Adolescents 12 to <18 Years of Age
Brief Summary The mRNA-1273 vaccine is being developed to prevent COVID-19, the disease resulting from Severe Acute Respiratory Syndrome coronavirus (SARS-CoV-2) infection. The study is designed to primarily evaluate the safety and reactogenicity of a single dose level of mRNA-1273 vaccine administered in 2 doses 28 days apart to an adolescent population.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Participants 12 to <18 years of age at the time of consent (Screening Visit, Day 0) who, in the opinion of the Investigator, are in good general health based on review of medical history and screening physical examination.
  • Investigator assessment that the participant, in the case of an emancipated minor, or parent(s)/legally acceptable representative(s) [LAR(s)] understand and is willing and physically able to comply with protocol-mandated follow up, including all procedures and provides written informed consent/assent.
  • Body mass index (BMI) at or above the third percentile according to World Health Organization (WHO) Child Growth Standards at the Screening Visit (Day 0)
  • Female participants of nonchildbearing potential may be enrolled in the study. Nonchildbearing potential is defined as premenarche or surgically sterile (history of bilateral tubal ligation, bilateral oophorectomy, hysterectomy).
  • Female participants of childbearing potential may be enrolled in the study if the participant has a negative pregnancy test at Screening (Day 0), on the day of the first injection (Day 1), and on the day of the second injection (Day 29); has practiced adequate contraception or has abstained from all activities that could result in pregnancy for at least 28 days prior to the first injection (Day 1); has agreed to continue adequate contraception through 3 months following the second injection (Day 29); and is not currently breastfeeding.

Exclusion Criteria:

  • Known history of SARS-CoV-2 infection or known close contact with anyone with laboratory-confirmed SARS-CoV-2 infection or COVID-19 within 2 weeks prior to vaccine administration
  • Travel outside of the United States in the 28 days prior to the Screening Visit (Day 0)
  • Pregnant or breastfeeding
  • Is acutely ill or febrile 24 hours prior to or at the Screening Visit (Day 0). Fever is defined as a body temperature ≥38.0°Celsius/≥100.4°Farenheit. Participants who meet this criterion may have visits rescheduled within the relevant study visit windows. Afebrile participants with minor illnesses can be enrolled at the discretion of the Investigator.
  • Prior administration of an investigational coronavirus (for example, SARS-CoV, Middle East Respiratory Syndrome [MERS-CoV]) vaccine
  • Current treatment with investigational agents for prophylaxis against COVID-19
  • Has 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
  • Current use of any inhaled substance (for example, tobacco or cannabis smoke, nicotine vapors)
  • History of chronic smoking (≥1 cigarette a day) within 1 year of the Screening Visit (Day 0)
  • History of illegal substance use or alcohol abuse within the past 2 years. This exclusion does not apply to historical cannabis use that was formerly illegal in the participant's state but is legal at the time of screening.
  • History of a diagnosis or condition that, in the judgment of the Investigator, may affect study endpoint assessment or compromise participant safety, specifically:

    • Congenital or acquired immunodeficiency, including human immunodeficiency virus (HIV) infection
    • Suspected active hepatitis
    • Has a bleeding disorder that is considered a contraindication to IM injection or phlebotomy
    • Dermatologic conditions that could affect local solicited adverse reaction (AR) assessments
    • History of anaphylaxis, urticaria, or other significant AR requiring medical intervention after receipt of a vaccine
    • Diagnosis of malignancy within the previous 10 years (excluding nonmelanoma skin cancer)
    • Febrile seizures
  • Receipt of:

    • Any licensed vaccine within 28 days before the first dose of investigational product (IP) or plans for receipt of any licensed vaccine through 28 days following the last dose of IP
    • Systemic immunosuppressants or immune-modifying drugs for >14 days in total within 6 months prior to the day of enrollment (for corticosteroids, ≥20 mg/day prednisone equivalent). Topical tacrolimus is allowed if not used within 14 days prior to the day of enrollment. Participants may have visits rescheduled for enrollment if they no longer meet this criterion within the Screening Visit window. Inhaled, nasal, and topical steroids are allowed.
    • Intravenous blood products (red cells, platelets, immunoglobulins) within 3 months prior to enrollment
  • Has donated ≥450 mL of blood products within 28 days prior to the Screening Visit (Day 0) or plans to donate blood products during the study
  • Participated in an interventional clinical study within 28 days prior to the Screening Visit (Day 0) or plans to do so while participating in this study
  • Is an immediate family member or has a household contact who is an employee of the research center or otherwise involved with the conduct of the study
