About Moderna’s R&D Day Presentation

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.

• Cytomegalovirus (CMV) vaccine (mRNA-1647): Positive interim data from Phase 2 study assessing the safety, reactogenicity, and immunogenicity of different dose levels of mRNA-1647 are now available. mRNA-1647 was generally safe and well tolerated. After the first vaccination, injection site pain was the most commonly reported solicited local adverse reaction (AR). The most common solicited systemic ARs were headache, fatigue, and myalgia in both CMV-seronegative and CMV-seropositive mRNA-1647 treatment groups. No serious adverse events (SAEs) were reported and no unsolicited events leading to study discontinuation occurred. After the 2nd vaccination, the rate and severity distribution of solicited ARs in the CMV-seronegative and CMV-seropositive mRNA-1647 treatment groups were generally similar. In CMV-seronegative participants, neutralizing antibody titers against epithelial cell infection were boosted to at least 12-fold over the baseline geometric mean titer (GMT) of CMV-seropositive participants. Neutralizing antibody titers against fibroblast infection were generally equivalent to the baseline GMT in CMV-seropositive participants. In CMV-seropositive participants, neutralizing antibody titers in the epithelial cell infection were boosted to GMTs at least 20-fold to greater than 32-fold over the respective baseline GMT after the 2nd vaccination. Neutralizing antibody titers against fibroblast infection boosted to levels at least 2-fold over the respective baseline GMT. Based on the interim analysis of the Phase 2 study, the 100 μg dose has been chosen for the Phase 3 pivotal study, expected to begin in 2021. Moderna owns worldwide commercial rights for mRNA-1647.
• COVID-19 vaccine (mRNA-1273): As of Wednesday, September 16, 2020, 25,296 participants have been enrolled in the Phase 3 COVE study and approximately 28% of participants enrolled cumulatively are from diverse communities. 10,025 participants have received their second vaccination. The protocol for the study being conducted in collaboration with the NIH and BARDA is now publicly available. On July 14, an interim analysis of the original cohorts in the NIH-led Phase 1 study evaluating a two-dose vaccination schedule of mRNA-1273 across three dose levels (25, 100, 250 µg) in 45 healthy adults ages 18-55 years was published in The New England Journal of Medicine and shows mRNA-1273 induced rapid and strong immune responses against SARS-CoV-2. mRNA-1273 was generally safe and well tolerated with no SAEs reported through Day 57. 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.
• Human metapneumovirus (hMPV) and parainfluenza type 3 (PIV3) vaccine (mRNA-1653): The first 10 seropositive pediatric participants (12-36 months of age) in the Phase 1 study of hMPV/PIV3 study (mRNA-1653) were dosed prior to the COVID-19 related study disruption. Sites have re-opened and are actively recruiting participants. Moderna owns worldwide commercial rights to mRNA-1653.
• Pediatric respiratory syncytial virus (RSV) vaccine (mRNA-1345): The FDA has completed its review of the Investigational New Drug (IND) application for mRNA-1345 and allowed it to proceed to clinic. mRNA-1345 is a vaccine against RSV in young children encoding for a prefusion F glycoprotein, which elicits a superior neutralizing antibody response compared to the postfusion state. The Company intends to combine mRNA-1345 with mRNA-1653, its vaccine against hMPV and PIV3, to create a combination vaccine against RSV, hMPV and PIV3. There is no approved vaccine for RSV. Moderna owns worldwide commercial rights to the combined mRNA-1345/mRNA-1653 vaccine.
• Seasonal influenza (flu): Moderna is entering the seasonal flu business. 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. Currently approved vaccines are ~40-60% effective and face significant challenges from strain mismatch¹; high-risk groups would benefit from higher efficacy, which the Company believes its mRNA platform may be capable of delivering.

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 are now available. mRNA-1944 was generally safe and well tolerated. No SAEs were reported; the most common adverse events were headache, nausea, myalgia, dizziness and chills. Administration of mRNA-1944 resulted in dose-dependent increases in levels of antibody against chikungunya (CHKV-24). Neutralizing antibodies were observed at all dose levels, indicating functional antibody production by mRNA-1944. Safety and increased CHKV-IgG production in the two-dose regimen shows the platform’s ability for repeat dosing.

Exploratory Modalities

Intratumoral Immuno-Oncology: These programs aim to drive anti-cancer T cell responses by injecting mRNA therapies directly into tumors.

• OX40L (mRNA-2416): The Phase 1/2 study of mRNA-2416 alone and in combination with durvalumab (IMFINZI^®) is ongoing. The Phase 2 dose expansion study of mRNA-2416 in combination with durvalumab in ovarian cancer patients is enrolling and the first patients have been dosed. Data from the Phase 1 study evaluating mRNA-2416 as a monotherapy were presented at the American Association for Cancer Research Annual Meeting and show mRNA-2416 is well tolerated when given as monotherapy at all dose levels studied with no dose-limiting toxicities reported. The observations of broad pro-inflammatory activity and beneficial changes in the tumor microenvironment with upregulation of PD-L1 support the evaluation of combination intratumoral mRNA-2416 with the anti-PD-L1 inhibitor durvalumab in solid tumors, which is ongoing in Part B of this study with a focus on advanced ovarian carcinoma. Moderna owns worldwide commercial rights to mRNA-2416.

Systemic Intracellular Therapeutics: These programs aim to deliver mRNA into cells within target organs as a therapeutic approach for diseases caused by a missing or defective protein.

• Methylmalonic acidemia (MMA) (mRNA-3704): Due to the COVID-19 pandemic, Moderna paused new enrollment and new site initiation for the Phase 1/2 study of mRNA-3704 to ensure the safety of these pediatric patients and their caregivers. During the pause, the Company implemented changes that the Company believes will ultimately help to accelerate clinical development including the introduction of a new drug product with better pharmacology (designated mRNA-3705) as well as a protocol revision to enhance operational performance and reflecting input from the patient and caregiver community. The Company plans to file new IND and CTA applications for mRNA-3705 and will focus development efforts on that candidate going forward. mRNA-3705 uses the same LNP formulation as mRNA-1944. Moderna owns worldwide commercial rights to mRNA-3705.
• Propionic acidemia (PA) (mRNA-3927): Due to the COVID-19 pandemic, Moderna paused new enrollment and new site initiation for its Phase 1/2 study of mRNA-3927 to ensure the safety of these pediatric patients and their caregivers. During the pause, the Company implemented changes that the Company believes will ultimately help to accelerate clinical development including a protocol amendment implementing a novel design to identify the optimal dose in the most efficient manner and to make the study less burdensome on patients, their families and clinical partners. mRNA-3927 uses the same LNP formulation as mRNA-1944. Moderna owns worldwide commercial rights to mRNA-3927.
