Both mRNA-1020 and mRNA-1030 target hemagglutinin and neuraminidase antigens, two major influenza surface glycoproteins that are essential across the viral life cycle
CAMBRIDGE, MA / ACCESSWIRE / April 11, 2022 / Moderna, Inc. (NASDAQ:MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today announced the first participants have been dosed in the Phase 1/2 study of the Company's seasonal influenza vaccine candidates, mRNA-1020 and mRNA-1030. This Phase 1/2 randomized, observer-blind, dose-ranging study will evaluate the safety, reactogenicity and immunogenicity of a single dose of mRNA-1020 or mRNA-1030 in healthy adults 18 years and older in the U.S. The mRNA-1020 and mRNA-1030 candidates each include eight mRNAs, targeting both hemagglutinin and neuraminidase at different doses and ratios. Similar to Moderna's influenza vaccine candidate mRNA-1010, mRNA-1020 and mRNA-1030 will target the strains recommended by the World Health Organization (WHO) for the prevention of influenza, including seasonal influenza A/H1N1, A/H3N2 and influenza B/Yamagata and B/Victoria. The Company intends to enroll approximately 560 participants in the study.
"We are pleased to apply Moderna's mRNA platform to address the longstanding design and manufacturing challenges associated with developing seasonal influenza vaccines. We believe that by targeting both hemagglutinin and neuraminidase, we can achieve broader immunity and higher vaccine efficacy against circulating influenza strains than traditional influenza vaccines. Moreover, we expect that our platform's flexibility in targeting multiple strains coupled with our ability to manufacture quickly will facilitate production of a vaccine that matches the predominant circulating influenza strain," said Stéphane Bancel, Chief Executive Officer of Moderna.
Worldwide, influenza leads to 3-5 million severe cases of flu and 290,000-650,000 flu-related respiratory deaths annually, despite the availability of influenza vaccines. Three main types of influenza viruses (A, B, and C) infect humans, with influenza A and B viruses causing significant morbidity and mortality. Although influenza A and B viruses cause seasonal flu epidemics, it is the influenza A viruses that lead to >95% of flu-related hospitalization in adults. Influenza A and B viruses carry two major surface glycoproteins that are essential across the viral life cycle: hemagglutinin (HA) and neuraminidase (NA). While the importance of targeting the viral HA with vaccines is well known, data suggests NA will also be an important vaccine target given that it has a slower rate of mutation and anti-neuraminidase antibodies have been shown to inhibit multiple stages of the virus life cycle and thereby contribute to protection against infection. Targeting both viral proteins may limit the virus' ability to escape the host immune responses through mutations and can potentially lead to better protection.
Moderna is pursuing an iterative approach to influenza vaccine development, with increasing levels of enhancements aimed at improving immune responses and increasing immunologic breadth. Though currently licensed influenza vaccines target predominantly the viral HA, in the mRNA-1020/1030 trial, Moderna adds neuraminidase antigens in order to target both major glycoproteins with the aim of promoting a broad and robust antibody response.
About Moderna
In over 10 years since its inception, Moderna has transformed from a research-stage company advancing programs in the field of messenger RNA (mRNA), to an enterprise with a diverse clinical portfolio of vaccines and therapeutics across seven modalities, a broad intellectual property portfolio in areas including mRNA and lipid nanoparticle formulation, and an integrated manufacturing plant that allows for rapid clinical and commercial production at scale. 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 and approval 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. Moderna has been named a top biopharmaceutical employer by Science for the past seven years. To learn more, visit www.modernatx.com.
