Moderna Announces Positive Top Line Data from Phase 2/3 Study of COVID-19 Vaccine in Children 6 to 11 Years of Age
Results are the first from pivotal study in children aged six years to under 12 years
Two 50 μg doses of mRNA-1273 were generally well tolerated and showed robust neutralizing antibody titers; primary immunogenicity endpoints were met
“We are encouraged by the immunogenicity and safety profile of mRNA-1273 in children aged 6 to under 12 years and are pleased that the study met its primary immunogenicity endpoints,” said
KidCOVE is a randomized, observer-blind, placebo-controlled expansion study to evaluate the safety, tolerability, reactogenicity and effectiveness of two 50 µg doses of mRNA-1273 given to healthy children 28 days apart. The study population is divided into 3 age groups (6 to <12 years, 2 to <6 years, and 6 months to <2 years). Today
This cohort enrolled 4,753 participants who were 6 to less than 12 years of age. In the trial, the SARS-Cov-2-neutralizing antibody geometric mean ratio (GMR) comparing the response in children to the response in young adults from the Phase 3 COVE study was 1.5 (95% Cl: 1.3, 1.8), with a seroresponse rate of 99.3%, representing a difference of 0.6% (95% CI: -2.8%, 2.8%) to the Phase 3 benchmark. These results demonstrate strong immune response in this cohort of children one month after the second dose and met the co-primary immunogenicity endpoints for 6 to less than 12 years olds in KidCOVE.
mRNA-1273 was generally well tolerated with a safety and tolerability profile generally consistent with the Phase 3 COVE study in adolescents and adults. The majority of adverse events were mild or moderate in severity. The most common solicited adverse events were fatigue, headache, fever, and injection site pain.
Safety data continue to accrue, and the study continues to be monitored by an independent safety monitoring committee. All participants will be monitored for 12 months after their second injection to assess long-term protection and safety. These data are subject to change based on ongoing data collection. The Company plans to submit data from the KidCOVE study to a peer-reviewed publication.
The enrollment for the 6 years to under 12 years is complete, but the Phase 2/3 study continues to enroll children ages 6 months to under 6 years of age. The Company has enrolled approximately 5,700 pediatric participants in the
In 10 years since its inception,
Moderna’s mRNA platform builds on continuous advances in basic and applied mRNA science, delivery technology and manufacturing, and has allowed the development of therapeutics and vaccines for infectious diseases, immuno-oncology, rare diseases, cardiovascular diseases and auto-immune diseases.
AUTHORIZED USE IN THE US
Moderna COVID-19 Vaccine is authorized for use under an Emergency Use Authorization (EUA) for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 18 years of age and older.
IMPORTANT SAFETY INFORMATION
- Do not administer the Moderna COVID-19 Vaccine to individuals with a known history of severe allergic reaction (e.g., anaphylaxis) to any component of the Moderna COVID-19 Vaccine.
Appropriate medical treatment to manage immediate allergic reactions must be immediately available in the event an acute anaphylactic reaction occurs following administration of the Moderna COVID-19 Vaccine. Monitor the Moderna COVID-19 Vaccine recipients for the occurrence of immediate adverse reactions according to the
Centers for Disease Control and Preventionguidelines (https://www.cdc.gov/vaccines/covid-19/clinical-considerations/managing-anaphylaxis.html).
- Postmarketing data demonstrate increased risks of myocarditis and pericarditis, particularly within 7 days following the second dose.
- Syncope (fainting) may occur in association with administration of injectable vaccines. Procedures should be in place to avoid injury from fainting.
- Immunocompromised persons, including individuals receiving immunosuppressive therapy, may have a diminished response to the Moderna COVID-19 Vaccine
- The Moderna COVID-19 Vaccine may not protect all vaccine recipients.
- Adverse reactions reported in clinical trials following administration of the Moderna COVID-19 Vaccine include pain at the injection site, fatigue, headache, myalgia, arthralgia, chills, nausea/vomiting, axillary swelling/tenderness, fever, swelling at the injection site, and erythema at the injection site, and rash.
- Anaphylaxis and other severe allergic reactions, myocarditis, pericarditis, and syncope have been reported following administration of the Moderna COVID-19 Vaccine during mass vaccination outside of clinical trials.
- Available data on the Moderna COVID-19 Vaccine administered to pregnant women are insufficient to inform vaccine-associated risks in pregnancy. Data are not available to assess the effects of the Moderna COVID-19 Vaccine on the breastfed infant or on milk production/excretion.
- Additional adverse reactions, some of which may be serious, may become apparent with more widespread use of the Moderna COVID-19 Vaccine.
- Vaccination providers must complete and submit reports to VAERS online at https://vaers.hhs.gov/reportevent.html. For further assistance with reporting to VAERS, call 1-800-822-7967. The reports should include the words “Moderna COVID- 19 Vaccine EUA” in the description section of the report.
