Moderna Reports Fourth Quarter and Fiscal Year 2020 Financial Results and Provides Business Updates

2021 Vaccine Manufacturing: Raises lower end of global manufacturing plan for 2021 from 600 million doses to 700 million doses; manufacturing is still working to supply up to 1 billion doses for 2021

2022 Vaccine Manufacturing: Based on the high demand from around the world for our COVID-19 vaccine and variant-based boosters, making new capital investments to increase capacity up to 1.4 billion doses in 2022

Commercial Subsidiaries: Company established 8 commercial subsidiaries in 2020 in North America and Europe and plans to expand in 2021 to Japan, South Korea and Australia

Moderna, Inc. MRNA, a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today reported financial results and provided business updates for the fourth quarter and fiscal year 2020 and highlighted pipeline progress.

"2020 was a historic year for Moderna. The team rose to the challenge to address the devastating COVID-19 pandemic in less than one year with our authorized vaccine. It is encouraging and humbling that more than 32 million doses of our vaccine have been administered in the U.S. and that millions of people around the world have been vaccinated with our vaccine to date. 2020 demonstrated the power of harnessing mRNA to make medicines and also demonstrated the speed and scalability of the Moderna platform that we have built over the last 10 years," said Stéphane Bancel, Chief Executive Officer of Moderna. "I believe that 2021 will be an inflection year for Moderna. We previously believed that mRNA would lead to approved medicines, and we were limited in our ambitions by the need for regular capital raises and keeping several years of cash to manage financing risk. We now know that mRNA vaccines can be highly efficacious and authorized for use, and we are a cash-flow generating commercial company. We opened commercial subsidiaries in 8 countries in 2020 and plan to add Japan, South Korea and Australia in 2021. We plan to accelerate and significantly increase our investments in science and grow our development pipeline faster. By executing on our 2021 priorities, we will advance our mission of delivering on the promise of mRNA science to create a new generation of transformative medicines for patients. This is just the beginning."

Summary of Program Highlights by Modality

Core Modalities

Prophylactic Vaccines: Moderna is developing vaccines against viral diseases where there is unmet medical need – including complex vaccines with multiple antigens for common diseases, as well as vaccines against threats to global public health. The Company's global public health portfolio is focused on epidemic and pandemic diseases for which funding has been sought from governments and non-profit organizations.

COVID-19 Vaccine Development

• Moderna COVID-19 Vaccine: On December 30, 2020, interim safety and primary efficacy results from the Phase 3 trial of the Moderna COVID-19 Vaccine (mRNA-1273) were published in the New England Journal of Medicine. Safety data continues to accrue, and the study continues to be monitored by an independent Data Safety Monitoring Board (DSMB) appointed by the National Institutes of Health (NIH). All participants in the COVE study will be monitored for two years after their second dose to assess long-term protection and safety. Today, the Company is sharing an update on the Phase 3 COVE study. An updated total of adjudicated COVID-19 cases among baseline seronegative participants in the COVE study starting two weeks following the second dose showed 690 cases to date, of which 639 cases of COVID-19 were observed in the placebo group versus 51 cases observed in the Moderna COVID-19 Vaccine group. Participants in the Phase 3 COVE study are in the process of being unblinded and cases will continue to accrue. On December 18, 2020, the U.S. Food and Drug Administration (FDA) authorized the emergency use of mRNA-1273, Moderna's vaccine against COVID-19, in individuals 18 years of age and older. Moderna has also received emergency (or other conditional, interim or provisional) authorization for use of its COVID-19 vaccine from health agencies in Canada, Israel, the European Union, the United Kingdom, Switzerland, Singapore and Qatar. Moderna is working with additional health agencies and with the World Health Organization on the authorization of its vaccine in additional jurisdictions. 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), partially supported the research and development of the Moderna COVID-19 Vaccine with federal funding under Contract no. 75A50120C00034. Moderna retains worldwide rights to develop and commercialize the Moderna COVID-19 Vaccine.

• Addressing Variants of Concern: On February 24, Moderna announced that it completed manufacturing of clinical trial material for its variant-specific vaccine candidate, mRNA-1273.351, against the SARS-CoV-2 variant known as B.1.351 first identified in the Republic of South Africa and has shipped doses to the NIH for a Phase 1 clinical trial that will be led and funded by the NIH's NIAID. The Company also provided an update on its strategy for addressing SARS-CoV-2 variants of concern.
  
  
  • Publication of Note: Letter to the editor in the New England Journal of Medicine published February 17, 2021, showed vaccination with the Moderna COVID-19 Vaccine produced neutralizing titers against all key emerging variants tested, including B.1.1.7 and B.1.351, first identified in the UK and Republic of South Africa, respectively. The study showed no significant impact on neutralizing titers against the B.1.1.7 variant relative to prior variants. A six-fold reduction in neutralizing titers was observed with the B.1.351 variant relative to prior variants.

• Further Clinical Studies of mRNA-1273
  
  
  • Phase 2/3 "TeenCOVE" study of mRNA-1273 in adolescents: The Phase 2/3 study of mRNA-1273 in adolescents ages 12-17 years has completed enrollment of 3,000 participants in the U.S.
  • Phase 2 "KidCOVE" study of mRNA-1273 in young children: The Phase 2 study of mRNA-1273 in pediatric population ages 6 months to 11 years will start in the near-term.
  • Phase 1/2 study of mRNA-1273 in Japan: The Phase 1/2 study of Moderna's vaccine candidate against COVID-19 (mRNA-1273 or TAK-919) in Japan, led by Takeda Pharmaceutical Co., Ltd is ongoing.

• Next-generation vaccine against COVID-19 (mRNA-1283): mRNA-1283 is a next-generation vaccine candidate against COVID-19 that encodes for the portions of the SARS-CoV-2 spike protein critical for neutralization, specifically the Receptor Binding Domain (RBD) and N-terminal Domain (NTD). The encoded mRNA-1283 antigen is shorter than mRNA-1273, and is being developed as a potential refrigerator stable mRNA vaccine that will facilitate easier distribution and administration by healthcare providers. mRNA-1283 is intended to be evaluated for use as a booster dose for previously vaccinated or infected individuals as well as in a primary series for seronegative individuals.

Vaccines requiring complex antigens and against highly prevalent infections

• Cytomegalovirus (CMV) vaccine (mRNA-1647): Positive interim data from the Phase 2 study assessing the safety, reactogenicity, and immunogenicity of different dose levels of mRNA-1647 were presented at Moderna's annual R&D Day. Based on the interim analysis of the Phase 2 study, the 100 μg dose has been chosen for the Phase 3 pivotal study, which is expected to begin in 2021. Moderna owns worldwide commercial rights for mRNA-1647.

• Epstein-Barr virus (EBV) vaccine (mRNA-1189): mRNA-1189 is a vaccine against EBV containing five mRNAs that encode viral proteins (gp350, gB, gp42, gH and gL) in EBV. Similar to Moderna's CMV vaccine (mRNA-1647), the viral proteins in mRNA-1189 are expressed in their native membrane-bound form for recognition by the immune system. Moderna is planning to begin a Phase 1 study of mRNA-1189 in 2021. There is no approved vaccine for EBV. Moderna owns worldwide commercial rights to mRNA-1189.

Vaccines against respiratory infections

• Human metapneumovirus (hMPV) and parainfluenza type 3 (PIV3) vaccine (mRNA-1653): Moderna is enrolling seropositive pediatric participants (12-36 months of age) in the Phase 1 study of hMPV/PIV3 study (mRNA-1653). The first cohort in this study has been fully enrolled. Moderna owns worldwide commercial rights to mRNA-1653.

• Respiratory syncytial virus (RSV) vaccine (mRNA-1345): mRNA-1345 is a vaccine against RSV encoding for a prefusion F glycoprotein, which elicits a superior neutralizing antibody response compared to the postfusion state. On January 11, Moderna announced its plan to amend the protocol to include evaluation of mRNA-1345 in older adults (greater than 50 years), in addition to the pediatric population, who are also at risk of significant RSV disease. In the pediatric population, the first three cohorts of younger adults in the Phase 1 age de-escalation study of mRNA-1345 are fully enrolled. The age range of toddlers in this de-escalation Phase 1 study has been amended to 12-59 months (from 12-36 months). In the older adult population, the first participant in the Phase 1 study of mRNA-1345 in the adult RSV vaccine has been dosed. The Company also intends to evaluate the potential of combinations of mRNA-1345 with its vaccines against other respiratory pathogens in children and separately in older adults. There is no approved vaccine for RSV. Moderna owns worldwide commercial rights to mRNA-1345.

• Seasonal influenza vaccine (mRNA-1010, mRNA-1020, mRNA-1030): Seasonal flu (type A and type B) epidemics occur seasonally and vary in severity each year, causing respiratory illnesses and placing substantial burden on healthcare systems. The WHO estimates globally about 3,000,000-5,000,000 severe cases of flu each year, and 290,000-650,000 flu-related respiratory deaths. Approximately 8% of the U.S. population experiences symptoms from flu each year, with 140,000-810,000 hospitalizations and 12,000-61,000 deaths per year. Peak flu activity is seen in temperate climates from fall to winter and is reflected in increases in outpatient visits, urgent care visits, and hospitalizations. In the U.S., the estimated average economic burden of seasonal influenza is approximately $11 billion per year. The Company plans to explore potential combination vaccines against flu, SARS-CoV-2, RSV and human metapneumovirus (hMPV). The Company's first-generation flu program will evaluate multiple candidates comprising multiple antigen combinations against the four seasonal viruses recommended by the WHO. The Company expects to begin Phase 1 clinical trials for this program in 2021.

Public health vaccines

• Zika virus vaccine (mRNA-1893):Moderna is preparing for a Phase 2 study of mRNA-1893, which is expected to begin in 2021. mRNA-1893 is being developed in collaboration with BARDA. Moderna owns worldwide commercial rights to mRNA-1893.

• HIV vaccine (mRNA-1644 & mRNA-1574): HIV is the virus responsible for acquired immunodeficiency syndrome (AIDS), a lifelong, progressive illness with no effective cure. Approximately 38 million people worldwide are currently living with HIV with 1.2 million in the U.S. Approximately 2 million new infections of HIV are acquired worldwide every year and approximately 690,000 people die annually due to complications from HIV/AIDS. The primary routes of transmission are sexual intercourse and IV drug use, putting young adults at the highest risk of infection. From 2000 to 2015, a total of $562.6 billion globally was spent on care, treatment and prevention of HIV, representing a significant economic burden. mRNA-1644, a collaboration with the International AIDS Vaccine Initiative (IAVI) and the Bill and Melinda Gates Foundation (BMGF), is a novel approach to HIV vaccine strategy in humans designed to elicit broadly Neutralizing HIV-1 Antibodies (bNAbs). A Phase 1 study for mRNA-1644 will use iterative human testing to validate the approach and antigens and multiple novel antigens will be used for germline-targeting and immuno-focusing. A second approach, mRNA-1574, is being evaluated in collaboration with the NIH and includes multiple native-like trimer antigens. The Company expects to begin Phase 1 studies for both mRNA-1644 and mRNA-1574 in 2021.

• Nipah virus (NiV) Vaccine (mRNA-1215): NiV is a zoonotic virus transmitted to humans from animals, contaminated food, or through direct human-to-human transmission and causes a range of illnesses including fatal encephalitis. Severe respiratory and neurologic complications of NiV have no treatment other than intensive supportive care. The case fatality rate among those infected is estimated at 40-75%. NiV outbreaks cause significant economic burden to impacted regions due to loss of human life and interventions to prevent further spread, such as the slaughter of infected animals. NiV has been identified as the cause of isolated outbreaks in India, Bangladesh, Malaysia, and Singapore since 2000 and is included on the WHO R&D Blueprint list of epidemic threats needing urgent R&D action. mRNA-1215 was co-developed by Moderna and the NIH's Vaccine Research Center (VRC).

• Pandemic influenza/H7N9 vaccine (mRNA-1851): Discussions regarding funding the Company's pandemic influenza/H7N9 vaccine program through approval are ongoing.
