Moderna Provides Business Update and Announces Three New Development Programs in Infectious Disease Vaccines

“The uniquely challenging year of 2020 for all of society proved to be an extraordinary proof-of-concept period for Moderna,” said Stéphane Bancel, Moderna’s chief executive officer. “Even as we have shown that our mRNA-based vaccine can prevent COVID-19, this has encouraged us to pursue more-ambitious development programs within our prophylactic vaccines modality. Today we are announcing three new vaccine programs addressing seasonal flu, HIV and the Nipah virus, some of which have eluded traditional vaccine efforts, and all of which we believe can be addressed with our mRNA technology. Beyond vaccines, we are extending our mRNA development work to a total of 24 programs across five therapeutic areas.”

Mr. Bancel will present an update on the Company and its pipeline of mRNA development programs on Monday, January 11, 2021 at 4:30 p.m. ET at the 39th Annual J.P. Morgan Healthcare Conference. The presentation will be followed by a question-and-answer session. A live webcast of both the presentation and question and answer session will be available under “Events & Presentations” in the investors section of Moderna’s website at investors.modernatx.com. A replay of the webcast will be archived on Moderna’s website for 30 days following the presentation.

Moderna currently has 24 mRNA development programs in its portfolio with 13 having entered the clinic. The Company’s updated pipeline can be found at www.modernatx.com/pipeline.

About Moderna’s New Infectious Disease Vaccine Development Programs

• Flu 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 in the US, 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 flu 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 the program in 2021.
  
• 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 National Institutes of Health (NIH) and includes multiple native-like trimer antigens. The Company expects to begin phase 1 clinical trials 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).

Moderna’s pipeline is organized into six modalities based on similar mRNA technologies, delivery technologies and manufacturing processes. The Company’s approach is to leverage early programs within a modality to generate clinical data and insights that reduce the technology risk of subsequent programs and accelerate the expansion of the pipeline in that modality. Positive phase 1, 2 and 3 data from Moderna’s infectious disease vaccine portfolio and positive phase 1 data from its chikungunya antibody program have de-risked its prophylactic vaccines and systemic therapeutics & cell surface modalities respectively. Beyond these core modalities, the Company has four exploratory modalities in which it is actively pursuing clinical proof of concept.

Summary of Program Updates 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 and often developed in collaborations with governments and non-profit organizations.

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 this year. 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. There is no approved vaccine for EBV. Moderna owns worldwide commercial rights to mRNA-1189.
  

Vaccines against respiratory infections

• Moderna COVID-19 Vaccine (mRNA-1273) authorization: On December 18, 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 or older. The Moderna COVID-19 Vaccine is also authorized by Canada, Israel, the United Kingdom and the European Union. Additional authorizations are currently under review in additional markets including Singapore, Switzerland and by the WHO. On December 30, 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. The primary endpoint of the Phase 3 COVE study was based on the analysis of COVID-19 cases confirmed and adjudicated starting two weeks following the second dose of vaccine. This final analysis was based on 196 cases, of which 185 cases of COVID-19 were observed in the placebo group versus 11 cases observed in the Moderna COVID-19 Vaccine group, corresponding to a 94% vaccine efficacy (95% CI 89.3-96.8%; p<0.0001). The most common solicited adverse reactions (ARs) after the two-dose series was injection site pain (86.0%). Solicited systemic adverse events occurred more often in the Moderna COVID-19 vaccine group (54.9% and 79.4%) than in the placebo (42.2% and 36.5%) group after both the first dose and the second dose respectively and were most commonly headache, fatigue and myalgia. While the majority of these ARs were mild (grade 1) or moderate (grade 2), there was a higher occurrence of severe (grade 3) reactions in the Moderna COVID-19 Vaccine group after the first (2.9%) and second (15.8%) injections. The majority of local solicited ARs occurred within the first one to two days after injection and generally persisted for a median of one to two days. Safety data continues to accrue, and the study continues to be monitored by an independent Data Safety Monitoring Board (DSMB) appointed by the NIH. All participants in the COVE study will be monitored for two years after their second dose to assess long-term protection and safety. Additional data to be collected will include longer term safety follow-up, duration of protection against COVID-19, and efficacy against asymptomatic SARS-CoV-2 infection. 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 mRNA-1273 with federal funding under Contract no. 75A50120C00034. A summary of the Company’s work to date on COVID-19 can be found here. Moderna retains worldwide rights to develop and commercialize mRNA-1273.

• Moderna COVID-19 Vaccine (mRNA-1273) additional clinical studies: Moderna is also conducting a phase 2/3 study of the Moderna COVID-19 Vaccine in adolescents 12 to under 18 years of age. Additional studies are planned to evaluate the Moderna COVID-19 Vaccine in pregnant women, children younger than 12 years, and those in special risk groups, such as the immunocompromised.

• Human metapneumovirus (hMPV) and parainfluenza type 3 (PIV3) vaccine (mRNA-1653): Sites have resumed dosing seropositive pediatric participants (12-36 months of age) in the Phase 1 study of hMPV/PIV3 study (mRNA-1653) following the COVID-19 related study disruption. 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. The first cohort of the phase 1 study of mRNA-1345 is fully enrolled. This phase 1 study includes initial dosing in younger adults, followed by age de-escalation into children. The Company today, announced its plan to amend the protocol to include evaluation of mRNA-1345 in older adults who are also at risk of significant RSV disease. Going forward, the Company 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.

Public Health Vaccines

• Zika virus vaccine (mRNA-1893): All dose cohorts (10, 30, 100 and 250 µg) in the phase 1 study of mRNA-1893 have completed enrollment. Moderna is preparing for a phase 2 study of mRNA-1893. mRNA-1893 is being developed in collaboration with the U.S. Biomedical Advanced Research and Development Authority (BARDA) within the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services. Moderna owns worldwide commercial rights to mRNA-1893.

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

Systemic Secreted & Cell Surface Therapeutics: In this modality, mRNA is delivered systemically to create proteins that are either secreted or expressed on the cell surface.

• Antibody against the chikungunya virus (mRNA-1944): Positive interim data from the Phase 1 study evaluating escalating doses of mRNA-1944 in the 0.6 mg/kg dose with steroid premedication cohort and two doses of 0.3 mg/kg (without steroid premedication) given one week apart cohort were presented at Moderna’s annual R&D Day and demonstrated dose-dependent increases in levels of antibody against chikungunya. Safety and increased CHKV-IgG production in the two-dose regimen shows the platform’s ability for repeat dosing.
