Contract #75A50120C00034
Modification P00008
C. Statement of Work
Updated with Modification P00008
Independently, and not as an agent of the United States Government, the contractor shall furnish all necessary services, qualified professional, technical, and administrative personnel, material, equipment and facilities, not otherwise provided by the Government under the terms of this contract, as needed to perform the tasks set forth below.
mRNA-1273 Vaccine Development (WBS 1.0)
The Contractor, Moderna, Inc. (“Moderna”) shall execute the preclinical, clinical, and chemistry, manufacturing and controls (CMC) activities required to license a vaccine against the SARS-CoV-2 virus (hereafter referred to as “mRNA-1273”). Building upon early clinical development already underway, this proposal will support the late stage development, including the demonstration of clinical efficacy and generation of a dataset supportive of licensure. Moderna will additionally evaluate the platform manufacturing capabilities relative to the needs for supply in response to a pandemic.
* Program Management (WBS 1.1) - Updated with Mod P00007
mRNA-1273 Program Management (WBS 1.1.1)
Moderna’s mRNA-1273 program team is composed of a multidisciplinary, highly matrixed, group of functional leads with experience in, and responsibility for, integrating plans and operationalizing strategies across Research, Toxicology, CMC, Regulatory Affairs, Clinical Development, Medical Affairs, Market Access and Launch Readiness in support of vaccine deployment under Emergency Use Authorization and Quality. Collectively, the team has advanced ten programs to first-in-human studies within five years. The group will be led by a program lead (PL) who will oversee and coordinate the activities necessary to meet the program objective of licensure. The PL will be the point of accountability for the development and deployment of mRNA-1273. [***]. The Sub Principal Investigator will be responsible for ensure sufficient manufacturing capacity and production of mRNA-1273. A program management office (PMO) will be responsible for managing the cost and schedule constraints of the contract via an integrated master schedule and corresponding budget, identifying and managing program risk, and ensuring contract compliance. With the input from the mRNA-1273 project team, the PMO will be responsible for coordinating the drafting of and management to an integrated development plan. Upon execution of the contract, weekly meetings with BARDA will be held to monitor program performance and monthly and annual reports will be will delivered to BARDA for the record. Moderna will contribute a portion of the subcontractor program management effort to support the contract.
Nonclinical Toxicology (WBS 1.2)
Development and Reproductive Toxicology of mRNA-1273 (WBS 1.2.2.1)
To assess the risk of administering the vaccine to pregnant women, a complete GLP rat developmental and reproductive toxicology (DART) study is planned. Female Sprague Dawley rats will be dosed at the highest anticipated clinical dose level and include a control arm of phosphate-buffered saline (PBS). As is typical for DART evaluations for vaccines, the animals will be immunized three times prior to mating and two times during gestation. Each group will

have two cohorts (one group will undergo Cesarean section with examination of the uteri and embryos; the other group will have natural delivery and will be terminated at weaning).
Nonclinical (WBS 1.3)
For the purposes of this proposal it is assumed that the VRC continues to support nonclinical activities to develop murine and non-human primate efficacy studies, and animal models to assess the potential of vaccine- enhanced disease. The scope of work below will execute additional robustness experiments in these developed models.
Assess Disease Enhancement (WBS 1.3.3.1)
The CoV spike protein expressed by the mRNA-1273 vaccine is stabilized in the prefusion conformation which should be optimal for inducing high quality antibody responses with low binding antibody to neutralizing antibody ratios. mRNA delivery and induction of CD8 T cells and Th1 CD4 T cells will avoid Th2-biased responses. The SARS-CoV-2 S protein expressed by the mRNA-1273 vaccine is stabilized in the pre-fusion conformation which should be optimal for inducing high functional antibody responses with low binding antibody to neutralizing antibody ratios, as it has been seen in RSV DS-Cav1 clinical trials and 2P-stabilized CoV S animal studies. In addition, mRNA vaccines induce Th1 skewed response as has been evident in several pre-clinical and clinical vaccine programs at Moderna, including pandemic flu and CMV (PMID 28457665, 29456015). By expressing pre-fusion SARS-CoV-2 S delivered with mRNA we should induce CD8 T cells and Th1-biased CD4 T cell responses as shown in both human, NHP, and murine studies, thus avoiding a Th2- biased response.
We plan to perform studies in mouse and NHPs to assess the theoretical risk of vaccine induced disease enhancement triggered by CoV infection following vaccination with imRNA-1273. [***]
[***]
Ralph Baric is also developing a human ACE-2 transgenic mouse model, resulting in viremia and lung pathology upon wild-type SARS-CoV-2 infection. This model should facilitate evaluation of wild-type SARS- CoV-2 virus and will also be used to evaluation protection from mRNA-1273 vaccination. This model is however still under development and data are unlikely to become available before June/July 2020.
Finally, Vincent Munster (NIH/NIAID) has developed a Rhesus macaque model of SARS-CoV infection. After challenge animals get sick but infection is not lethal. Decreased respiration and irregular breathing, weight loss, fever spike at day 1 and evidence of pneumonia are all observed. In addition, hematological evidence of disease is seen, as well as viremia and shedding in nose, throat, and rectum up to day 10. Unlike what is observed clinically a high challenge dose of virus is required, and animals recover without intervention. Animals will be immunized with limiting doses of mRNA-1273 to allow breakthrough infection and endpoints relevant for disease enhancement will be collected. Results from these challenge studies may become available by end of June 2020.

Establish a Surrogate of Protection (WBS 1.3.3.2)
The primary endpoint for accelerated approval of a SARS-CoV-2 vaccine would be a neutralization assay. This endpoint must be supported with a body of pre-clinical work that demonstrates a correlation between neutralizing titers and efficacy and that quantifies a protective serologic threshold titer using the same neutralization assay. Murine and NHP efficacy models are being developed in parallel to the Phase 1 clinical study. Building on data from these preliminary models and studies, Moderna will conduct NHP efficacy and murine passive transfer studies to confirm and refine the surrogate of protection.
** Clinical (WBS 1.4) -- Updated with Mod P00008
A Phase 1 study of mRNA-1273 in 120 healthy subjects 18-55 years of age will evaluate the safety and immunogenicity of two injections (28 days apart) at four dose levels (25, 50, 100 and 250 ^g). The proposed Phase 2 study will enroll n=600 healthy subjects (>18 years) to receive two injections, 28 days apart, of placebo or 50 or 100 ^g mRNA-1273, at 1:1:1, age stratified (18-55 yrs; >55 yrs).
The total safety database from the mRNA-1273 Phase 1 and Phase 2 studies will be approximately 445 adult participants exposed and approximately 245 adult participants at the highest dose level. The proposed Phase 2 study (synopsis included below) is intended to support entry to subsequent Phase 3 study(ies). [***].
** Phase 2 Safety and Immunogenicity Study (WBS 1.4.2.1) - Updated with Mod P00007
Immediately following dose selection in the initial Phase 1 study the program will initiate a Phase 2 clinical study. The P201 study will confirm the safety and immunogenicity results from the open-label Phase 1, again testing a two-dose administration series 28d apart. Its assumed that 600 participants, randomized 1:1:1 active: placebo, testing a two dose levels of mRNA-1273. Enrollment will be age-stratified participants 18 year of age and above into two age cohorts. Primary objectives will include standard clinical safety evaluation with conventional safety and SARS-CoV-2-specific IgG endpoints though a neutralizing antibody assay would be preferred if available. Secondary objectives will evaluate of the specific humoral response against SARS-CoV-2 by binding and neutralizing antibody (nAb) response. Safety will be followed through 6 months post-last vaccination and primary immunogenicity endpoint will be measured at D57. The study will enroll in the US under IND. The study will assess COVID-19 as exploratory endpoint which may extend the duration of follow-up accordingly. Clinical trial assessments will include measurement of SARS-CoV-2 S-specific binding antibody and neutralizing activity in sera. This will provide an indication of vaccine-induced antibody quality and relative potency. Historically, immune-complex mediated lung pathology has been associated with a high ratio of binding to functional antibody activity. In addition, vaccine-induced T cell responses will be evaluated by peptide pool stimulation to define the pattern of cytokine production. [***]. To support the EUA, an interim clinical study synopsis will be drafted based on D57 safety and immunogenicity data.
** Pediatrics (WBS 1.4.2.3 Updated with Mod P00007 and WBS 1.4.2.4)
Moderna will conduct an initial pediatric study plan (PSP) under Pediatric Research Equity Act requirements during the IND phase. A deferral will be requested for children less than 6 months
3 of 8

of age at the time of initial BLA approval. Having demonstrated the mRNA-1273 is safe, tolerated, and effective in adults, Moderna will test the safety and immunogenicity of mRNA-1273 in a pediatric population with an aged-based step-down design.
The P203 study is a Phase 2/3, randomized, observer-blind, placebo controlled, study to evaluate the safety, reactogenicity, and effectiveness of mRNA-1273 SARS-CoV-2 vaccine in 3000 healthy adolescents 12 to < 18 years of age. Participants will be randomly assigned to receive injections of either 100 ^g of mRNA-1273 vaccine or a placebo control in a 2:1 randomization ratio. The goal of the study is to seek an indication for use of mRNA 1273 (100 ^g IM, given as 2 injections, 28 days apart) in the 12 to < 18 year age group. The basis for demonstrating vaccine effectiveness is proposed to be met by serum antibody (Ab) response measured in this adolescent age group. The approach to inferring vaccine effectiveness will depend on whether or not an accepted serum Ab threshold conferring protection against COVID-19 has been established. If an Ab threshold of protection has been established, effectiveness will be inferred based on the proportion of adolescent study participants with serum Ab levels (on study Day 57) meeting or exceeding the Ab threshold. If an Ab threshold of protection has not been established, effectiveness will be inferred based on demonstrating non-inferiority of the geometric mean value of serum nAb from adolescent participants compared to the geometric mean value of serum nAb from adults enrolled in the ongoing clinical endpoint efficacy trial (Study P301).
This adolescent study will monitor all participants for a total of 12 months following the second dose of vaccine or placebo. Safety assessments will include solicited ARs (7 days post each injection), unsolicited AEs (28 days post each injection), medically attended adverse events (MAAEs), serious adverse events (SAEs), and adverse event of special interest (AESI) (pediatric MIS C) throughout the study period.
The 204 study is a Phase 2/3, randomized, observer-blind, placebo controlled, study to evaluate the safety, reactogenicity, and effectiveness of mRNA-1273 SARS-CoV-2 vaccine in approximately 6,000 healthy children 6 months to < 12 years of age. Approximately 6,000 participants will be enrolled in a dose-escalation, age de-escalation design testing 50 and 100 ug dose levels across three age groups: 6 to <12 years of age, 2 to <6 years of age and 6 month to <2 years of age. Safety and Immunogenicity endpoints will follow the P203. The study will enroll in the US and up to two ex-US countries (e.g. Canada and/or Australia).
** Phase 3 Pivotal Study (WBS 1.4.3.1) - — Updated with Mod P00008
Phase 3 Pivotal Study (WBS 1.4.3.1). The Phase 3 mRNA-1273-P301 study will confirm the trends observed during the Phase 1 and 2 trials, evaluating safety and efficacy in a larger number of subjects aged 18 and above. Approximately 30,000 subjects will be enrolled according to 1:1 randomization (active: placebo). Primary objectives will be 1) to demonstrate the efficacy of mRNA-1273 to prevent COVID-19 and 2) to evaluate the safety and reactogenicity of 2 injections of the mRNA-1273 vaccine given 28 days apart. Secondary objectives will evaluate: the efficacy of mRNA-1273 to prevent severe COVID-19; the efficacy of mRNA-1273 to prevent virologically confirmed SARS-CoV-2 infection or COVID-19 regardless of symptomatology or severity; VE against a broad definition of COVID-19 disease; VE to prevent
4 of 8

death due to COVID-19 disease; VE against all-cause mortality; the efficacy of mRNA-1273 to prevent COVID-19 after the first dose of investigational product (IP); the efficacy of mRNA-1273 to prevent COVID-19 in all study participants, regardless of evidence of prior SARS-CoV-2 infection; the efficacy of mRNA-1273 to prevent asymptomatic SARS-CoV-2 infection.
The sample size of this Phase 3 is driven by the total number of cases to demonstrate VE (mRNA-1273 vs. placebo) to prevent COVID-19. [***].
[***]
On issuance of the EUA, in agreement with the FDA and OWS, the P301 study will offer vaccine to participants that were randomized to receive placebo and the study will transition to an open label study. All 30K participants will return for a Participant Decision Visit. Participants will complete an updated ICF, a sera and NP swab sample will be collected to test for asymptomatic infection, and participants randomized to the placebo arm will be offered vaccine. After unblinding the sponsor will continue to leverage the clinical trial infrastructure. Doubling the exposed population will reduce the incidence of rare events potentially detectable with high confidence in the trial to approximately 1/10,000 or 0.01%.
Lot to Lot Consistency (WBS 1.4.3.2)
Based on FDA feedback received on 27 Aug this study is no longer required for licensure.
Post-Authorization Safety and Effectiveness Studies (WBS 1.4.4.1, 1.4.4.2, 1.4.4.3 and 1.4.4.4)
During EUA, Moderna will conduct signal refinement analyses using tokenized real-world data within the United States. The population complements but does not duplicate the populations under observation in the CDC’s Vaccine Safety DataLink and the FDA’s CMS programs. This real-world data infrastructure will significantly decrease the time between safety signal identification and evaluation. Using the tokenized data the sponsor will be able to conduct an early post-authorization general safety study at a point in time approximately 8-12 months after the initiation of the study to provide further reassurance that prespecified adverse events of interest are being addressed during the EUA period.
Further, Moderna is planning to establish an observational pregnancy cohort study, (e.g., with the Vaccines and Medications in Pregnancy Surveillance System (VAMPSS) Mother to Baby cohort). Unlike a traditional passive pregnancy registry this approach will enable the calculation of incidence rates for adverse pregnancy and birth outcomes. It will also enable the identification of key confounders and non-medically attended outcomes (e.g., spontaneous abortions) that are incompletely recorded in secondary healthcare records.
With respect to continued evaluation of effectiveness after crossover, early in the EUA period, tokenized real- world data will provide COVID-19 incidence rates within geographic zones surrounding the clinical trial sites as a proxy for rates among unvaccinated individuals. The Moderna envisions conducting one descriptive analysis involving both trial and geographic incidence rates 3-6 months after EUA and before broad product distribution removes the utility of this early approach. Simultaneously, a prospective cohort study within a large integrated
5 of 8

healthcare delivery system (e.g., a Kaiser Permanente region) will be initiated to formally evaluate the vaccine effectiveness (VE) and long-term effectiveness of mRNA-1273 at the patient level with a concurrent comparator group. Effectiveness outcomes to be evaluated include effectiveness against severe COVID-19, Follow-up time will be two years after the last dose, and interim analyses will be performed based on the number of events of the primary effectiveness outcome to assess durability of protection. A final analysis including 1-dose VE and 2-dose VE will be evaluated. Moderna will contribute by funding these EUA studies. The USG will obtain access to the data.
Medical Affairs (WBS 1.4.6.1) — Updated with Mod P00007
The Medical Affairs group will provide scientific and clinical support for mRNA-1273 through the EUA period. This will include developing patient and healthcare provider materials to support vaccine deployment under EUA and establishing a non-promotional call center to support vaccine distribution and administration. Given the importance of vaccine confidence during EUA, special consideration will be given to scientific communication on the mRNA platform, vaccine development in a pandemic, and the safety, immunogenicity and effectiveness data of mRNA-1273. Moderna will contribute by funding these activities. The USG will obtain access to the data.
Regulatory (WBS 1.5)
IND Preparation and Filing (WBS 1.5.1.1)
Moderna’s Regulatory Affairs group, in close collaboration with BARDA, will work to draft a comprehensive regulatory master plan to guide the preclinical, CMC and clinical development of mRNA-1273 within the first 90 days of the contract. An original investigational new drug application (IND) will be filed with the United States Food and Drug Administration (FDA) to support the clinical development of the Moderna product from Phase 2 onwards.
IND Maintenance (WBS 1.5.1.2)
The Moderna-owned IND will be maintained to support the desired clinical development plan. As needed, meetings will be conducted to receive feedback and gain concurrence on the specifics of the development activities with the FDA. Moderna will file for Emergency Use Authorization, following the FDA guidance of EUA for COVID-19 vaccines. A product-specific VRBPAC will be held.
***BLA Submission (WBS 1.5.2.1) - Updated with ModP00008
Moderna will submit a Biologics License Application (BLA) and seek approval for the mRNA-1273 vaccine.
*** The Pharmacovigilance (WBS 1.5.3.1) Updated with Mod P00008
Moderna will conduct standard pharmacovigilance for all active mRNA-1273 clinical studies.
CMC (WBS 1.6)
CTM Manufacture for Phase 2 (WBS 1.6.3.2)
Clinical trial materials for the P201 study will be supplied using the AMP process. The target yield of each lot is approximately [***] vials; consequently, manufacture of up to five drug product (DP) lots is expected to deliver [***] total vials. The DP will be a frozen liquid stored at
6 of 8

[***]. The DP vials will be labeled and packaged by Moderna to support clinical testing in the US.
Process Development for Late Stage Clinical Supply (WBS 1.6.3.3)
mRNA Process Development
Technical Development will confirm and optimize the process parameters for mRNA manufacture. [***]
[***]
BLA Readiness (WBS 1.6.3.8)
In support of the Biologics License Application (BLA) due to the nature of the proposed timeline, it is likely that Moderna will need to complete some of process validation activities, primarily process characterization, after the completion of process performance qualification and before BLA filing. Moderna intends to rapidly develop a robust process for clinical manufacturing and PPQ, and then fully describe the acceptable design space for the process prior to BLA filing. Other activities to support this BLA filing, such as completing raw material qualification activities; if not included in the BLA submission, will require a supplement to the initial BLA. In the initial BLA filing Moderna will describe its control strategy to cover the gap between initial BLA filing and the BLA supplement.
Process Development for Full Commercial Scale (WBS1.6.4.1)
The following section outlines the process development activities [***]. The goal of this work is to demonstrate the capability to produce mRNA-1273 at a scale that can support clinical demand.
[***]
Controls (Analytical and Validation) (WBS 1.6.5)
Potency Assay Development and Implementation (WBS 1.6.5.1)
[***]
Analytical Method Development and Validation (WBS 1.6.5.2)
Moderna has established a set of analytical methods that are applied to the release and stability testing of intermediates and DP. These methods are sufficient to assure the identity, strength, quality, purity and potency of the final product, and will have been qualified for use for mRNA-1273 as part of the Phase 2 CTM campaign. Robustness of product release and stability methods, structural characterization and identification of impurities to further support product specifications, product comparability assessment will continue to support Phase 3 development and licensure.
Characterization Assay Development and Implementation (WBS 1.6.5.3)
A heightened characterization panel of analytical techniques will be used to assess any process modifications and to confirm process reproducibility for both drug substance and drug product during process development and scale up. As the applicability of the methods used in the heightened panel to elucidate quality attributes of drug substance and drug product is determined, these methods may be elevated to the respective release panel.
7 of 8

Stability Studies (WBS 1.6.5.4)
Throughout the program, many studies will be undertaken [***]. This includes studies using development bench scale material, engineering lot material, and GMP material. This body of data will be used to apply interim and long-term shelf life to the drug product and process intermediates.

Statement of Work (SOW) P204 - Modification P00009
P204 Pediatrics (WBS 1.4.2.4)
mRNA-1273-P204 is a Phase 2/3, 2-part, open-label, dose-escalation, age de-escalation, randomized, observer-blind, placebo-controlled, expansion study intended to infer the effectiveness of mRNA-1273 in children aged 6 months to < 12 years. The study population will be divided into 3 age groups (6 to < 12 years, 2 to < 6 years, and 6 months to < 2 years) and up to 3 dose levels (25, 50, and 100 ^g) of mRNA- 1273 will be evaluated.
The study will be conducted in 2 parts. Part 1 of the study will be open label and consist of dose-escalation, age de-escalation in 750 participants (see Table below for the number of participants in each age group) to select the dose for each age group. Part 2 of the study will be placebo-controlled, observer-blind evaluation of the selected dose in 6,000 participants (2,000 participants in each age group). No participants in Part 1 will participate in Part 2 of the study. The total participants in mRNA-1273-P204 study is 6,750 participants.
The study will begin with the oldest age group (6 to < 12 year) and age de-escalate. Each age group will begin with Part 1 and advance to Part 2. The mRNA-1273 investigational vaccine or placebo will be administered as 2 intramuscular (IM) injections, approximately 28 days apart.
The mRNA-1273 dose levels that will be evaluated in each age group in Part 1 and Part 2 of the study are given in the Table below. Only the 6-month to < 2-year age group will receive the 25 ^g dose level.

Age Group | Part 1 | Part 2
mRNA-1273 25 gg | mRNA-1273 50 gg | mRNA-1273 100 gg | Selected Dose Level of mRNA-1273 From Part 1 | Placebo
6 to < 12 years |  | Study arm 1 (n=75) | Study arm 2 (n=75) | Study arm 8 (n=1500) | Study arm 9 (n=500)
2 to < 6 years |  | Study arm 3 (n=75) | Study arm 4 (n=75) | Study arm 10 (n=1500) | Study arm 11 (n=500)
6 months to < 2 years | Study arm 5 (n=150) | Study arm 6 (n=150) | Study arm 7 (n=150) | Study arm 12 (n=1500) | Study arm 13 (n=500)

The study will enroll in the US and Canada. The result of mRNA-1273-P204 study is to expand the label indication to 6 months to < 12 years old.
