Moderna Announces First Participants Dosed in Study Evaluating COVID-19 Booster Vaccine Candidates
CAMBRIDGE, Mass.--(BUSINESS WIRE)--Mar. 10, 2021-- Moderna, Inc. (Nasdaq: MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today announced that the first participants have been dosed with the Company’s modified COVID-19 vaccines, designed to address the potential need for booster vaccine candidates, in an amendment to the ongoing Phase 2 clinical study.
mRNA-1273.351 encodes for the prefusion stabilized Spike protein of the SARS-CoV-2 variant B.1.351, first identified in the Republic of South Africa, and is being assessed as a booster vaccine to increase the breadth of response to emerging variants with key-receptor-binding domains (RBD) mutations. mRNA-1273.211 is a multivalent candidate which combines mRNA-1273, Moderna’s authorized vaccine against ancestral strains, and mRNA-1273.351 in a single vaccine, designed to elicit a broad immune response as both a primary series and when administered as a boost to those who have previously received mRNA-1273.
Previously published data has shown that vaccination with the Moderna COVID-19 Vaccine produced neutralizing titers against all key variants tested, including B.1.1.7, first identified in the UK, and B.1.351, with a 6-fold reduction in neutralizing titers against B.1.351. Out of an abundance of caution, Moderna is pursuing a clinical development strategy against these emerging variants.
In parallel, NIAID, part of the National Institutes of Health (NIH), will conduct a Phase 1 clinical trial to assess the monovalent and multivalent modified mRNA-1273 vaccines as a primary series in naïve individuals and as a booster vaccine in those previously vaccine with mRNA-1273. NIAID will initiate this study after receiving safe-to-proceed authorization from the FDA. NIAID will provide additional information when the trial begins. The clinicaltrials.gov identifier is NCT04785144.
About Moderna
In 10 years since its inception, Moderna has transformed from a science research-stage company advancing programs in the promising-but-still-unproven field of messenger RNA (mRNA), to an enterprise with its first medicine having treated millions of people, a diverse clinical portfolio of vaccines and therapeutics across six modalities, a broad intellectual property portfolio in areas including mRNA and lipid nanoparticle formulation, and an integrated manufacturing plant that allows for both clinical and commercial production at scale and at unprecedented speed. Moderna maintains alliances with a broad range of domestic and overseas government and commercial collaborators, which has allowed for the pursuit of both groundbreaking science and rapid scaling of manufacturing. Most recently, Moderna’s capabilities have come together to allow the authorized use of one of the earliest and most-effective vaccines against the COVID-19 pandemic.
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. Today, 24 development programs are underway across these therapeutic areas, with 13 programs having entered the clinic. Moderna has been named a top biopharmaceutical employer by Science for the past six years. To learn more, visit www.modernatx.com.
