CAMBRIDGE, Mass.–(BUSINESS WIRE)–Apr. 13, 2021– Moderna today announced clinical and supply updates on its COVID-19 Vaccine program. New results from a preclinical study of the Company’s COVID-19 variant-specific vaccine candidates showed that the Company’s variant-specific booster vaccine candidates (mRNA-1273.351 and mRNA-1273.211) increase neutralizing titers against SARS-CoV-2 variants of concern. To date, the Company has delivered approximately 132 million doses of the Moderna COVID-19 Vaccine globally.
“The Moderna team continues to make important progress with our COVID-19 Vaccine. We are looking forward to having the clinical data from our variant-specific booster candidates, as well as clinical data from the Phase 2/3 study of our COVID-19 Vaccine in adolescents,” said Stéphane Bancel, Chief Executive Officer of Moderna. “The new preclinical data on our variant-specific vaccine candidates give us confidence that we can proactively address emerging variants. Moderna will make as many updates to our COVID-19 vaccine as necessary until the pandemic is under control.”
Update on the Phase 3 COVE Study of the Moderna COVID-19 Vaccine
Today, the Company is sharing an update on the Phase 3 COVE study of the Moderna COVID-19 Vaccine (mRNA-1273). An updated review of adjudicated cases has identified over 900 cases of COVID-19 in the COVE study as of April 9th, including over 100 cases of severe COVID-19, as defined in the protocol, with a median follow-up of approximately 6 months post dose 2. Vaccine efficacy starting two weeks following the second dose and based on the updated adjudicated cases remains consistent with prior updates, including greater than 90% against all cases of COVID-19, and greater than 95% against severe cases of COVID-19.
As of April 13, all placebo participants have been offered the Moderna COVID-19 Vaccine and 98% of those have received the vaccine.
The COVE study is ongoing and reported results remain preliminary. Throughout the year, Moderna will be sharing updated data from the Phase 3 COVE study including efficacy against asymptomatic infection, genotyping data, additional antibody persistence data and information regarding potential correlates of protection.
The Phase 2/3 TeenCOVE study of mRNA-1273 at the 100 µg dose level in adolescents ages 12-17 is fully enrolled with approximately 3,000 participants in the U.S.
The Phase 2/3 KidCOVE study of mRNA-1273 in the pediatric population ages 6 months-11 years is currently enrolling. The Company expects to enroll 6,750 healthy pediatric participants in the U.S. and Canada into this two-part, dose escalation study. In Part 1, each participant ages 2 years to less than 12 years may receive one of two dose levels (50 μg or 100 μg). Also in Part 1, each participant ages six months to less than 2 years may receive one of three dose levels (25 μg, 50 μg and 100 μg). An interim analysis will be conducted to determine which dose will be used in Part 2, the placebo-controlled expansion portion of the study.
Antibody Persistence Data out to 6 Months Published in The New England Journal of Medicine
Antibody persistence data out to 6 months following the second dose of the Moderna COVID-19 Vaccine were recently published in The New England Journal of Medicine. This study analyzed 33 healthy adult participants in the NIH-led Phase 1 study of Moderna’s COVID-19 Vaccine at 6 months following the second 100 μg dose (day 209). As detected by three distinct serologic assays, antibodies elicited by the Moderna COVID-19 Vaccine persisted through 6 months after the second dose. Antibody decay was estimated using two approaches and was consistent with published observations of convalescent patients with COVID-19 through 8 months after symptom onset.
Preclinical Data on Variant-Specific Booster Candidates
New preclinical data on the Company’s variant-specific booster vaccine candidates have been submitted as a preprint to bioRxiv and will be submitted for peer-reviewed publication. These variant-specific vaccine candidates include mRNA-1273.351, which is more specifically targeted against the SARS-CoV-2 variant known as B.1.351 first identified in the Republic of South Africa, and a multivalent booster candidate, mRNA-1273.211, which combines mRNA-1273 (Moderna’s authorized vaccine against ancestral strains) and mRNA-1273.351 in a single vaccine.
Both mRNA-1273.351 and mRNA-1273.211 increase neutralizing titers against SARS-CoV-2 variants of concern in Balb/c mice. Specifically, this preclinical data confirms improved neutralizing titers with the mRNA-1273.351 vaccine primary series. The multi-valent vaccine provided the broadest level of immunity. A boost at 6 months with mRNA-1273.351 closed the neutralizing titer gap for the variants of concern. Following the mRNA-1273.351 boost, neutralizing titers were comparable between the ancestral strain (Wuhan) and the new B.1.351 variant. The Company’s Phase 2 study to evaluate three approaches to boosting is ongoing.
Global Supply Update
In the fourth quarter of 2020, the Company delivered approximately 17 million doses to the U.S. government. For the first quarter of 2021, the Company delivered approximately 88 million doses to the U.S. government and approximately 14 million doses to other customers. Through April 12, 2021, Moderna cumulatively delivered approximately 132 million doses globally, including approximately 117 million doses to the U.S. government and approximately 15 million doses delivered from Moderna’s ex-U.S. supply chain. The Company remains on track to deliver the second 100 million doses to the U.S. government by end of May 2021 followed by another 100 million additional doses by end of July 2021. The ex-U.S. supply chain was established approximately one quarter behind the U.S. supply chain and continues to ramp up.
Cerebral Venous Sinus Thrombosis (CVST) or Thrombotic Events
On April 13, the Company issued a statement on cerebral venous sinus thrombosis (CVST). A comprehensive assessment of the totality of the available safety data for mRNA-1273 after over 64.5 million doses administered globally does not suggest an association with CVST or thrombotic events, based on analyses performed using data through March 22, 2021. The number of vaccinations was derived from the U.S. Centers for Disease Control and Prevention (CDC) website, European Centre for Disease Prevention and Control (ECDC) website and inferred for other countries based on distribution and the proportion of doses distributed administered in ex-U.S. settings.

About the Moderna COVID-19 Vaccine
The Moderna COVID-19 Vaccine is an mRNA vaccine against COVID-19 encoding for a prefusion stabilized form of the Spike (S) protein, which was co-developed by Moderna and investigators from the National Institute of Allergy and Infectious Diseases’ (NIAID) Vaccine Research Center. The first clinical batch, which was funded by the Coalition for Epidemic Preparedness Innovations, was completed on February 7, 2020 and underwent analytical testing; it was shipped to the National Institutes of Health (NIH) on February 24, 2020, 42 days from sequence selection. The first participant in the NIAID-led Phase 1 study of the Moderna COVID-19 Vaccine was dosed on March 16, 2020, 63 days from sequence selection to Phase 1 study dosing. On May 12, 2020, the U.S. FDA granted the Moderna COVID-19 Vaccine Fast Track designation. On May 29, 2020, the first participants in each age cohort were dosed in the Phase 2 study of the vaccine. On July 8, 2020, the Phase 2 study completed enrollment.
Results from the second interim analysis of the NIH-led Phase 1 study of the Moderna COVID-19 Vaccine in the 56-70 and 71+ age groups were published on September 29, 2020 in The New England Journal of Medicine. On November 30, 2020, Moderna announced the primary efficacy analysis of the Phase 3 study of the vaccine conducted on 196 cases. On November 30, 2020, the Company also announced that it filed for Emergency Use Authorization with the U.S. FDA and a Conditional Marketing Authorization (CMA) application with the European Medicines Agency. On December 18, 2020, the U.S. FDA authorized the emergency use of the Moderna COVID-19 Vaccine in individuals 18 years of age or older. Moderna has also received authorization for its COVID-19 vaccine from health agencies in Canada, Israel, the European Union, the United Kingdom, Switzerland, Singapore, Qatar and Taiwan. Additional authorizations are currently under review in other countries and by the World Health Organization.
The Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services (HHS) is supporting the continued research and development of the Company’s COVID-19 vaccine development efforts with federal funding under contract no. 75A50120C00034. BARDA is reimbursing Moderna for 100 percent of the allowable costs incurred by the Company for conducting the program described in the BARDA contract. The U.S. government has agreed to purchase supply of mRNA-1273 under U.S. Department of Defense contract no. W911QY-20-C-0100.
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.
