CAMBRIDGE, MA / ACCESSWIRE / May 4, 2023 / Moderna, Inc. (NASDAQ:MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today reported financial results and provided business updates for the first quarter of 2023.

"We had a strong first quarter, with $1.9 billion in revenue, clearly indicating that we are on our way to deliver on the $5 billion of signed Advance Purchase Agreements for 2023. In addition, we are encouraged by the progress of new COVID-19 vaccine contracts in the U.S. for this fall with pharmacy chains, hospital networks and multiple U.S. government agencies. Similar discussions are ongoing with Japan, the EU, and other key markets such as Australia, which recently ordered additional COVID-19 vaccines," said Stéphane Bancel, Chief Executive Officer of Moderna. "At AACR, we presented detailed results for the treatment of melanoma with our individualized neoantigen therapy in combination with Keytruda, showing a 44% reduction of recurrence or risk of death in melanoma compared to Keytruda alone. These data could represent a profound change in the treatment of melanoma, and we are quickly beginning Phase 3 trials in melanoma as well as lung cancer. We also are pleased with our progress in rare disease, where we have now advanced to the dose-expansion phase of our investigational mRNA therapy for propionic acidemia, and have upcoming interim data being shared at ASGCT this month. At the same time, we are fully preparing for potential commercial launches of two products in 2024, our RSV and flu vaccines."

Recent progress includes:

Respiratory Vaccines
Moderna's respiratory pipeline includes Phase 3 trials against RSV, influenza, and a next-generation COVID-19 candidate. The pipeline includes four additional influenza vaccines with expanded antigens, vaccines against other respiratory pathogens (e.g., hMPV), and six combination vaccine programs.

Commercial and Phase 3 trials

COVID-19
According to current FDA guidance for COVID-19 vaccination, individuals who are 65 years of age or older and those who are immunocompromised are now eligible to receive an additional dose. New COVID-19 vaccination recommendations are expected from the FDA following the upcoming June strain-selection meeting.

Moderna's next-generation, refrigerator-stable COVID-19 vaccine, mRNA-1283, has demonstrated encouraging results in multiple clinical studies and recently began dosing participants in a Phase 3 trial.

RSV
Moderna's RSV vaccine candidate, mRNA-1345, met its primary efficacy endpoint in older adults, and topline data were released in the first quarter. Additional updates were presented at recent medical conferences (RSVVW and ECCMID), demonstrating consistently high efficacy across the clinical spectrum of RSV disease in adults aged 60 years and up. No cases of Guillain-Barré syndrome (GBS) or other demyelinating events have been reported among mRNA-1345 trial participants to date. Based on these results, Moderna expects to submit for regulatory approval.

Flu
The Company's first influenza vaccine candidate, mRNA-1010, is currently being evaluated in Phase 3 trials. A Phase 3 trial (P301) was conducted in the Southern Hemisphere to evaluate safety and non-inferior immunogenicity compared to a licensed flu vaccine; interim results from that study were previously announced in February. An additional Phase 3 trial (P302) is being conducted in the Northern Hemisphere to evaluate safety and non-inferior efficacy compared to a licensed flu vaccine. The independent DSMB has completed the first interim analysis of efficacy and informed the company that mRNA-1010 did not meet the statistical threshold necessary to declare early success and recommended that the trial continues with efficacy follow-up towards the next analysis. The DSMB did not identify any safety concerns.

A preliminary analysis of immunogenicity from a subset of participants in the P302 trial has also been completed. In this analysis, mRNA-1010 demonstrated geometric mean titer ratios consistent with superiority against both influenza A strains (A/H1N1, A/H3N2) and consistent with non-inferiority against both influenza B strains (B/Victoria, B/Yamagata) relative to the licensed comparator. The P302 study will continue until the end of the current flu season.

The Company has also initiated a Phase 3 immunogenicity trial (P303) to test an updated formulation of mRNA-1010 that is expected to lead to improved immune responses against influenza B strains and is intended to enable licensure of mRNA-1010 through accelerated approval.

Combination Respiratory Vaccines
The Phase 1/2 trial of mRNA-1083, targeting COVID-19 + flu, using the Company's next-generation COVID-19 vaccine candidate, mRNA-1283, and seasonal flu vaccine candidate mRNA-1010, has initiated enrollment.

Latent Virus Vaccines
Phase 3 trial
The pivotal Phase 3 study of Moderna's CMV vaccine candidate (mRNA-1647), known as CMVictory, is ongoing, with enrollment more than 50% complete. The adolescent trial for mRNA-1647 has dosed its first participants.

Therapeutics
The Company's therapeutics portfolio spans immuno-oncology, rare diseases, autoimmune diseases, and cardiovascular diseases.

Immuno-oncology
Moderna and Merck's recent announcement and presentation at the American Association for Cancer Research (AACR) on April 16, 2023, demonstrated that the Phase 2b KEYNOTE-942/mRNA-4157-P201 trial of mRNA-4157/V940, an investigational individualized neoantigen therapy, in combination with pembrolizumab met the primary efficacy endpoint of improving recurrence-free survival (RFS) versus standard of care pembrolizumab for the adjuvant treatment of patients with stage III/IV melanoma following complete resection. Adjuvant treatment with mRNA-4157/V940 in combination with pembrolizumab reduced the risk of recurrence or death by 44% (HR=0.56 [95% CI, 0.31-1.08]; one-sided p-value=0.0266) compared with pembrolizumab alone. The 12-month RFS rate was 83.4% (95% CI, 74.7-89.3) and 77.1% (95% CI, 62.5-86.6) in the combination and control arms, respectively. The 18-month RFS rate was 78.6% (95% CI, 69.0-85.6) and 62.2% (95% CI, 46.9-74.3) in the combination and control arms, respectively.

A second AACR presentation reviewed data from a subgroup analysis to assess RFS in biomarker-high and -low subgroups across study arms. Irrespective of tumor mutational burden (TMB) status, the results indicate that targeting an individual patient's unique tumor mutations with mRNA-4157/V940 demonstrates improved RFS when administered in combination with pembrolizumab compared to pembrolizumab monotherapy. The association between TMB and mRNA-4157/V940 treatment effect will be further explored in upcoming planned studies.

Moderna and Merck plan to discuss results with regulatory authorities, initiate a Phase 3 study in melanoma in 2023, and rapidly expand to additional tumor types, including non-small cell lung cancer (NSCLC).

Rare diseases: Propionic Acidemia
The Phase 1/2 open-label, dose optimization trial of mRNA-3927, an mRNA therapeutic candidate for propionic acidemia (PA), has advanced to the dose-expansion phase to further evaluate safety and efficacy, and confirm the recommended dose for future clinical studies. This trial includes a dose optimization stage (cohorts 1-5), followed by a dose expansion stage with progression dependent on the safety of the preceding cohort. A total of 257 doses have been administered with no dose-limiting toxicities or study discontinuations due to drug-related treatment-emergent adverse events. Five of the 15 study participants have been dosed with over one year of continuous treatment. All eligible participants have elected to continue with treatment by participating in the Open-Label Extension Study. Interim data will be presented at the American Society of Gene & Cell Therapy (ASGCT) on May 18, 2023.

Moderna now has 47 programs¹ in development across 45 development candidates, of which 36 are currently in active clinical trials. The Company's updated pipeline can be found at www.modernatx.com/pipeline. Moderna and collaborators have published more than 140 peer-reviewed publications.

First Quarter 2023 Financial Results

Revenue: Total revenue for the first quarter of 2023 was $1.9 billion, compared to $6.1 billion in the same period in 2022, mainly due to a decrease in sales of the Company's COVID-19 vaccines. Product sales for the first quarter of 2023 were $1.8 billion, a decrease of 69%, compared to the same period in 2022, primarily driven by lower sales volume.

Cost of Sales: Cost of sales for the first quarter of 2023 was $792 million. In addition to unit driven manufacturing costs, this includes royalties of $86 million and the following charges: $148 million for inventory write-downs related to excess and obsolete COVID-19 products, unutilized manufacturing capacity of $135 million, and losses on firm purchase commitments and related cancellation fees of $95 million. These charges, other than royalties, were driven by costs associated with surplus production capacity and an overall lower demand forecast, primarily for lower income countries. Cost of sales as a percent of product sales was 43% of product sales, compared to 17% in the first quarter of 2022. The increase was driven by the aforementioned charges over lower product sales compared to the prior year, and higher manufacturing cost as the Company switched to smaller dose vials compared to the prior year, as well as lower product sales to absorb fixed manufacturing costs.

Research and Development Expenses: Research and development expenses for the first quarter of 2023 increased by 104% to $1.1 billion, in comparison to the same quarter of 2022. The growth in spending was mainly due to an increase in clinical trial-related expenses, largely driven by increased clinical development activities, particularly with respect to the Company's RSV, seasonal flu and CMV programs. The growth was also driven by an increase in personnel-related costs, due to increased headcount to support research and development efforts, and the Company's recently announced collaboration agreements with Life Edit and Generation Bio.

Selling, General and Administrative Expenses: Selling, general and administrative expenses for the first quarter of 2023 increased by 14% to $305 million, in comparison to the first quarter of 2022. The growth in spending was primarily due to increases in outside services spend and personnel-related costs, driven by commercial activities in support of the Company's marketed products and expansion.

Income Taxes: Income tax benefit for the first quarter of 2023 was $384 million, driven by the Company's full year outlook, which includes research and development credits, international provisions, and non-recurring items.

Net Income: Net income was $79 million in the first quarter of 2023, compared to net income of $3.7 billion for the first quarter of 2022.

Earnings Per Share: Diluted earnings per share was $0.19 in the first quarter of 2023, compared to diluted earnings per share of $8.58 for the first quarter of 2022.

2023 Commercial Updates

COVID-19: COVID-19 vaccine sales to Europe were $0.6 billion and sales to the rest of the world were $1.3 billion in the first quarter. The total of $1.8 billion in sales represents the vast majority of the projected $2 billion in sales from 2022 deferrals expected in the first half of 2023.² The Company reiterates its expectation of 2023 minimum sales of approximately $5.0 billion from previously announced COVID-19 vaccine Advanced Purchase Agreements. The Company estimates the U.S. annual COVID-19 market to be 100 million doses. The Company is in active supply discussions for new orders for fall of 2023 in the U.S., Japan, and the EU In the U.S., this could include:
