Study to enroll 60 participants previously vaccinated with mRNA-1273 in Phase 2, to evaluate booster vaccine candidates against the B.1.351 variant first identified in South Africa
CAMBRIDGE, MA, USA I March 10, 2021 IModerna, 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. An amendment to the Phase 2 study will enroll 60 participants previously vaccinated with mRNA-1273 to receive a single booster dose of either:
- 20 µg of a variant-specific booster candidate, mRNA-1273.351, based on the B.1.351 variant first identified in the Republic of South Africa (N=20)
- 50 µg of mRNA-1273.351 (N=20)
- 50 µg of 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 (N=20)
In a previous protocol amendment, Phase 2 study participants vaccinated with mRNA-1273 have been offered a single 50 µg booster dose of mRNA-1273. Dosing in this protocol extension is ongoing.
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 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 Disease’s (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. Food and Drug Administration granted the Moderna COVID-19 Vaccine Fast Track designation. On May 29, 2020, the first participants in each age cohort: adults ages 18-55 years (n=300) and older adults ages 55 years and above (n=300) were dosed in the Phase 2 study of the vaccine. On July 8, 2020, the Phase 2 study completed enrolment. 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 July 28, 2020, results from a non-human primate preclinical viral challenge study evaluating the vaccine were published in The New England Journal of Medicine. On July 14, 2020, an interim analysis of the original cohorts in the NIH-led Phase 1 study of the vaccine was published 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 3, 2020, a letter to the editor was published in The New England Journal of Medicine reporting that participants in the Phase 1 study of the Moderna COVID-19 Vaccine retained high levels of neutralizing antibodies through 119 days following first vaccination (90 days following second vaccination). 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 and Qatar. 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 mRNA-1273 with $955 million in 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.
