CAMBRIDGE, Mass.–(BUSINESS WIRE)–Moderna, Inc. (Nasdaq: MRNA), a clinical stage biotechnology company
pioneering messenger RNA (mRNA) therapeutics and vaccines to create a
new generation of transformative medicines for patients, today reported
financial results for the first quarter of 2019 and provided business
updates.

“We continue to execute against our corporate objectives as we progress
clinical studies across our development portfolio, introduce a new mRNA
rare disease development candidate and focus on identifying additional
modalities and disease targets,” said Stéphane Bancel, Moderna’s chief
executive officer. “We are excited to pursue a treatment to potentially
address the underlying cause of glycogen storage disease type 1a, and we
believe this candidate also reflects the continued productivity of our
mRNA platform. At yesterday’s annual Science Day event, we presented new
insights into our mRNA and delivery science, including the potential
delivery of mRNA to white blood cells. While our team has additional
research to perform in this area, we look forward to being able to bring
new candidates into development as we continue working to help patients
with a wide range of serious diseases.”

Moderna currently has 21 mRNA development candidates in its portfolio
with 11 in clinical studies. Across Moderna’s pipeline, more than 1,000
subjects have been enrolled in clinical studies. The Company’s updated
pipeline can be found at www.modernatx.com/pipeline.

Summary of Recent Highlights by Modality

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 epidemic and pandemic threats to global public health.

• Respiratory syncytial virus (RSV) vaccine (mRNA-1777 and
  mRNA-1172): Merck has filed an investigational new drug (IND)
  application with the U.S. Food and Drug Administration (FDA) and plans
  to run a Phase 1 study for a follow-on development candidate
  (mRNA-1172), a vaccine for RSV which has shown enhanced potency in
  preclinical studies and uses a Merck proprietary formulation. As a
  result, further development of mRNA-1777 has been paused and next
  steps will be determined based on data from the new mRNA-1172 Phase 1
  study.
• Varicella zoster virus (VZV) vaccine (mRNA-1278): Based
  on an assessment of the commercial opportunity, research priorities
  and other factors, Merck has discontinued preclinical
  development of mRNA-1278, an investigational vaccine for VZV (the
  virus that causes shingles). Merck has returned rights to Moderna, and
  the Company will not continue development at this time.
• Cytomegalovirus (CMV) vaccine (mRNA-1647): The first three dose
  levels in Moderna’s ongoing study of mRNA-1647 are fully enrolled, and
  the study is currently enrolling subjects into the fourth (300μg) dose
  cohort. The Phase 1 study is randomized, observer-blind and
  placebo-controlled with the goal of evaluating the safety and
  immunogenicity of mRNA-1647, a vaccine against the pentamer and gB
  complexes of CMV.

• Presentation of note: Moderna presented data from its Phase 1
  studies of vaccines against viruses that cause respiratory diseases at
  the European Society for Pediatric Infectious Disease (ESPID) meeting
  held in Ljubljana, Slovenia.

Cancer Vaccines: These programs focus on stimulating a
patient’s immune system with antigens derived from tumor-specific
mutations to enable the immune system to elicit a more effective
anti-tumor response.

• Personalized cancer vaccines (PCVs) (mRNA-4157, NCI-4650): Two
  abstracts for Moderna PCV programs were accepted for presentation at
  the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting.
  Moderna will present new updates to clinical data from the Company’s
  Phase 1 study of mRNA-4157, a PCV being studied alone in patients with
  resected solid tumors and in combination with Merck’s pembrolizumab in
  patients with unresectable solid tumors. The National Cancer Institute
  (NCI) will also present data from its Phase 1 study of PCV NCI-4650, a
  monotherapy for patients with advanced metastatic cancers. The two
  abstracts are:
  • Moderna: A Phase 1 multi-center study to assess the safety,
    tolerability and immunogenicity of mRNA-4157 alone in patients
    with resected solid tumors and in combination with pembrolizumab
    in patients with unresectable solid tumors. Selected for a
    Poster Discussion, Saturday, June 1, 1:15 PM-2:45 PM CST.
  • NCI: Immunogenicity and tolerability of personalized mRNA
    vaccine mRNA-4650 encoding defined neoantigens expressed by the
    autologous cancer. Selected for a Poster Session, Saturday,
    June 1, 8:00 AM-11:00 AM CST.

Moderna and NCI PCVs are designed and manufactured individually based on
the DNA sequence of a patient’s tumor, encoding for peptides containing
mutations found in their cancer in order to deliver multiple unique and
personalized neoantigens in a single vaccine. Moderna’s PCV now includes
up to 34 neoantigens, up from 20. The NCI program uses Moderna’s mRNA
technology but uses a different neoantigen selection process and study
design.

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

• OX40L (mRNA-2416): Moderna continues to enroll patients
  in its Phase 1/2 trial evaluating mRNA-2416, an intratumoral injection
  of mRNA encoding OX40L, for the treatment of advanced
  relapsed/refractory solid tumor malignancies and lymphomas and is also
  preparing to start enrollment of a Phase 2 expansion cohort of the
  study in patients with advanced ovarian carcinoma.
• OX40L + IL23 + IL36γ (Triplet) (mRNA-2752): Moderna
  continues to dose a second cohort (0.5 mg) of patients in its ongoing
  Phase 1 study evaluating the safety and tolerability of mRNA- 2752 for
  the treatment of advanced or metastatic solid tumor malignancies or
  lymphoma. mRNA-2752 is an investigational mRNA immuno-oncology therapy
  that encodes a novel combination of three immunomodulators designed to
  activate the immune system to recognize and eradicate tumors that are
  resistant to checkpoint inhibitors. It is being studied both as a
  single agent and in combination with AstraZeneca’s durvalumab or
  tremelimumab.
• IL12 (MEDI1191): At the American Academy of Cancer Research
  (AACR) Annual Meeting in March, Moderna’s strategic collaborator
  AstraZeneca shared preclinical data that supported advancing MEDI1191
  into a Phase 1 clinical study. MEDI1191 is an mRNA encoding for IL12,
  a potent immunomodulatory cytokine, which aims to enhance immune
  response in immunologically “cold” tumors. AstraZeneca is now leading
  an open-label, multi-center study of intratumoral injections of
  MEDI1191 alone and in combination with a checkpoint inhibitor.

Systemic Secreted Therapeutics: In this modality, mRNA is
delivered systemically to create proteins that are secreted outside the
cell with the aim of producing pharmaceutically active proteins with
therapeutic effects across the human body.

• Antibody against the chikungunya virus (mRNA-1944): Moderna has
  completed enrollment of the second dose level cohort (0.3 mg/kg)
  of its Phase 1 study evaluating the safety and tolerability of
  escalating doses of mRNA-1944 via intravenous infusion in healthy
  adults. This is the first monoclonal antibody encoded by mRNA to be
  dosed in a human and the first development candidate from the
  Company’s systemic secreted therapeutics modality to start clinical
  testing. The formulation used for mRNA-1944 is also utilized in
  Moderna’s MMA program.

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): Site initiation
  activities are ongoing for the Phase 1 study of mRNA-3704, Moderna’s
  program for the rare metabolic disease MMA.
• Propionic acidemia (PA) (mRNA-3927): The European Commission
  (EC) has adopted the recommendation from the Committee for Orphan
  Medicinal Products for orphan drug designation for mRNA-3927, a
  development candidate for propionic acidemia (PA).

  Additionally,
  enrollment continues in the Company’s global natural history study of
  MMA and PA (MaP study). This is a global, multi-center,
  non-interventional study for patients with confirmed diagnosis of MMA
  due to methylmalonyl-CoA mutase (MUT) deficiency or PA and is designed
  to identify and correlate clinical and biomarker endpoints for these
  disorders.

• Glycogen storage disease type 1a (GSD1a) (mRNA-3745): Moderna
  has selected a new development candidate for the rare inherited
  metabolic disease GSD1a. GSD1a results in a buildup of glycogen in
  tissues and an inability to regulate glucose, due to mutations within
  the enzyme glucose 6-phosphatase (G6Pase), leading to life-threatening
  hypoglycemia and long-term liver and kidney damage. Patients with this
  disease incur metabolite buildup associated with hepatomegaly
  (enlarged livers), which can lead to benign and malignant liver
  tumors. mRNA-3745 is an IV-administered mRNA encoding G6Pase enzyme,
  designed to restore deficient or defective intracellular enzyme
  activity. This is expected to increase blood glucose levels, while
  decreasing levels of uric acid, lactic acid and triglycerides. In a
  mouse model, Moderna has shown the ability to improve hypoglycemia and
  other metabolic abnormalities associated with GSD1a, and mice treated
  with G6Pase mRNA showed a dose-dependent improvement in fasting
  glycemia and a reduction in both serum triglycerides and liver weight.
  There are approximately 6,500 GSD1a patients in the United States and
  the European Union. Disease management requires a strict diet to
  maintain blood glucose levels with some patients requiring a liver
  transplant. Preclinical data from this program were shared at the 22^nd
  Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT).
• Other systemic therapeutic preclinical research: Also at ASGCT
  2019, Moderna and academic collaborators gave oral presentations and
  shared data from seven preclinical animal studies using mRNA-based
  therapies for several rare diseases including: ornithine
  transcarbamylase deficiency (OTC) and maple syrup urine disease (MSUD)
  (in collaboration with the Gene Therapy Program at the Perelman School
  of Medicine, University of Pennsylvania); arginase-1 (ARG1) deficiency
  (in collaboration with the University of California, Los Angeles
  Department of Surgery and Department of Molecular and Medical
  Pharmacology); factor VIII deficiency (hemophilia A) (in collaboration
  with the Seattle Children’s Research Institute); adult-onset type II
  citrullinemia (CTLN2); and progressive familial intrahepatic
  cholestasis type 3 (PFIC3). These programs are early research
  initiatives and presently are not Moderna development candidates.
• Publication of note: In March, Moderna published data in
  the American Journal of Human Genetics that showed preclinical
  proof-of-concept for administering mRNA encoding human ɑ-Gal, across
  species, as a potential systemic mRNA therapy for the treatment of
  Fabry disease.

First Quarter 2019 Financial Results

• Cash Position: Cash, cash equivalents and investments as of
  March 31, 2019 and December 31, 2018 were $1.55 billion and $1.69
  billion, respectively.
• Net Cash Used in Operating Activities: Net cash used in
  operating activities was $143.9 million for the three months ended
  March 31, 2019 compared to $111.4 million for the three months ended
  March 31, 2018. Net cash used in operating activities includes $22.0
  million and $25.0 million in the first quarter of 2019 and 2018,
  respectively, of in-licensing payments to Cellscript, LLC and its
  affiliate, mRNA RiboTherapeutics, Inc., to sublicense certain patent
  rights. After 2019, we have no further in-licensing payment obligation
  to Cellscript and its affiliate.
• Cash Used for Purchases of Property and Equipment: Cash used
  for purchases of property and equipment was $7.6 million for the three
  months ended March 31, 2019 compared to $31.9 million for the three
  months ended March 31, 2018.
• Revenue: Total revenue was $16.0 million for the three months
  ended March 31, 2019 compared to $29.0 million for the three months
  ended March 31, 2018. On January 1, 2019, we adopted Accounting
  Standards Codification (ASC) Topic 606, Revenue from Contracts with
  Customers (ASC 606), using the modified retrospective transition
  method applied to those contracts which were not completed as of
  January 1, 2019. The total revenue decrease was mainly attributable to
  the decrease in collaboration revenue from all of our strategic
  alliances, particularly AstraZeneca and Merck, largely driven by the
  adoption of ASC 606. Total revenues under the previous revenue
  recognition standard would have been $37.9 million for the first
  quarter of 2019.
• Research and Development Expenses: Research and development
  expenses were $130.6 million for the three months ended March 31, 2019
  compared to $90.1 million for the three months ended March 31, 2018.
  The increase was primarily due to an increase in personnel related
  costs, including stock-based compensation, mainly driven by an
  increase in the number of employees supporting research and
  development programs, an increase in clinical trial and manufacturing
  costs, an increase in lab supplies and materials for our preclinical
  studies and clinical trials, and an increase in consulting and outside
  services costs.
• General and Administrative Expenses: General and administrative
  expenses were $27.3 million for the three months ended March 31, 2019
  compared to $16.3 million for the three months ended March 31, 2018.
  The increase was mainly attributable to an increase in personnel
  related costs, including stock-based compensation, primarily driven by
  an increase in the number of employees, and consulting and outside
  services costs, both of which were related to operating as a publicly
  traded company.
• Net Loss: Net loss was $132.7 million for the three months
  ended March 31, 2019 compared to $72.4 million for the three months
  ended March 31, 2018.
