— Advanced mRNA infectious disease vaccine programs, including Sanofi Pasteur initiation of influenza clinical trial; clinical trial results from two mRNA vaccines anticipated this year —

— Continued progress in development of mRNA therapeutics for pulmonary diseases including preclinical next-generation cystic fibrosis (CF) and primary ciliary dyskinesia (PCD) programs —

LEXINGTON, Mass., Aug. 05, 2021 (GLOBE NEWSWIRE) — Translate Bio (Nasdaq: TBIO), a clinical-stage messenger RNA (mRNA) therapeutics company developing a new class of potentially transformative medicines to treat or prevent debilitating or life-threatening diseases, today announced financial results for the second quarter ended June 30, 2021 and reviewed recent corporate updates.

“Since we started our partnership with Sanofi in 2018, we have moved two mRNA vaccine candidates through preclinical development to investigational new drug (IND) application submission, and initiated Phase 1 clinical trials for COVID-19 and seasonal influenza. We have made significant progress in the development of our mRNA vaccines through this collaboration, demonstrating some of the key attributes of our mRNA platform, including speed, flexibility and scale,” said Ronald Renaud, chief executive officer, Translate Bio. “This transaction is a validation of our mRNA platform and a testament to the talented Translate Bio team. Joining Sanofi will deepen our existing relationship, and we believe it will strengthen the team’s ability to bring innovative and life-changing medicines to patients. Sanofi’s diverse therapeutics portfolio can also further demonstrate the advantages of our technology in areas beyond vaccines, building on the pioneering work done over the last 10+ years at Translate Bio.”

Second Quarter 2021 and Recent Updates

mRNA Vaccine Programs for Infectious Diseases (Sanofi Pasteur Collaboration)

• Initiated seasonal influenza mRNA vaccine clinical trial (MRT5400 and MRT5401) with Sanofi Pasteur: In June 2021, the Company announced the start of the Phase 1 clinical trial for MRT5400 and MRT5401, two formulations of a monovalent seasonal influenza mRNA vaccine. The Phase 1 clinical trial will inform the next steps of the mRNA-based influenza vaccine program. Interim results from this trial are expected by the end of 2021.
• Achieved influenza manufacturing milestone: In June 2021, the Company achieved a manufacturing milestone under the collaboration with Sanofi Pasteur related to its influenza mRNA vaccine program. Translate Bio received a $50 million payment from Sanofi Pasteur for the successful manufacture, release and delivery of clinical drug product to supply the Phase 1 seasonal influenza clinical trial.

mRNA Therapeutics Programs

• Generated positive preclinical data for next-generation CF program: Data demonstrates CFTR protein expression in the lungs of animals after the delivery of the next-generation CF product candidate using the intended inhaled route of administration.
• Presented positive preclinical PCD data at the American Thoracic Society (ATS) 2021 International Conference: In May 2021, the Company presented positive results from a preclinical study of a novel mRNA-based therapeutic designed to treat PCD. The study results suggest that delivery of an mRNA-based therapeutic to the lungs can lead to the expression of DNAI1, which could potentially restore mucociliary clearance.

Second Quarter 2021 Financial Results and Financial Guidance

Translate Bio ended the second quarter of 2021 with $667.2 million in cash, cash equivalents and investments and 75,343,712 shares of common stock outstanding.

Translate Bio reported a net income of $17.1 million for the three months ended June 30, 2021, compared to a net loss of $36.3 million for the same period in 2020.

Collaboration revenue was $72.6 million and $16.3 million for the three months ended June 30, 2021 and 2020, respectively. Revenue was derived from the collaboration with Sanofi and is recorded as a percentage of the estimated transaction price based on the extent of progress toward completion. The transaction price increased in the three months ended June 30, 2021 compared to the same period in 2020 which resulted in an increase in revenue.

Operating expenses for the three months ended June 30, 2021 were $56.6 million, compared to $53.0 million for the same period in 2020, and were comprised of the following:

• Research and development expenses of $40.5 million during the second quarter of 2021, compared to $29.0 million for the same period in 2020. The increase is primarily due to continued development of the Company’s discovery program as well as increases in occupancy and personnel-related costs.
• General and administrative expenses of $11.9 million during the second quarter of 2021, compared to $8.6 million for the same period in 2020. The increase is primarily due to increases in personnel-related costs and professional fees.
• Operating expenses of $4.2 million for change in the fair value of contingent consideration related to future potential milestone and earnout payment obligations. The operating expense was primarily attributed to an increase in the fair value of the contingent consideration liability due to the time value of money due to the passage of time and a decrease in the discount rate.

About Translate Bio
Translate Bio is a clinical-stage mRNA therapeutics company developing a new class of potentially transformative medicines to treat diseases caused by protein or gene dysfunction, or to prevent infectious diseases by generating protective immunity. Translate Bio is primarily focused on applying its technology to treat pulmonary diseases with a lead pulmonary candidate being evaluated as an inhaled treatment for cystic fibrosis (CF) in a Phase 1/2 clinical trial. Additional pulmonary diseases are being evaluated in discovery-stage research programs that utilize a proprietary lung delivery platform. Translate Bio also believes its technology may apply broadly to a wide range of diseases, including diseases that affect the liver. Additionally, the platform may be applied to various classes of treatments, such as therapeutic antibodies or protein degradation. Translate Bio is also pursuing the development of mRNA vaccines for infectious diseases under a collaboration with Sanofi Pasteur.
