-- Completed dosing in single-ascending dose portion of Phase 1/2 clinical trial in cystic fibrosis; data expected 3Q19 --

LEXINGTON, Mass., May 09, 2019 (GLOBE NEWSWIRE) -- Translate Bio TBIO, a clinical-stage messenger RNA (mRNA) therapeutics company developing a new class of potentially transformative medicines to treat diseases caused by protein or gene dysfunction, today announced financial results for the first quarter ended March 31, 2019 and reviewed recent corporate achievements and updates.

"This quarter, we have continued to focus on progressing our programs for rare genetic diseases while also advancing our mRNA therapeutic (MRT) platform to fuel future pipeline programs," said Ronald Renaud, chief executive officer of Translate Bio. "We are excited to share that we have completed dosing in the single-ascending dose portion of the ongoing Phase 1/2 clinical trial for MRT5005 in patients with cystic fibrosis and anticipate reporting interim data from this trial in the third quarter of this year."

First Quarter 2019 and Recent Updates

• Completed dosing in single-ascending dose (SAD) portion of Phase 1/2 clinical trial of MRT5005 for the treatment of cystic fibrosis (CF): Translate Bio completed dosing of all patients in the three dose cohorts of the SAD portion of the ongoing first-in-human clinical trial of MRT5005, an mRNA therapeutic product candidate that is designed to treat all patients with CF by addressing the underlying cause of the disease, including those with limited or no cystic fibrosis transmembrane conductance regulator (CFTR) protein. The Company now expects to report interim data from this trial in the third quarter of 2019. Patient dosing continues in the ongoing multiple-ascending dose portion of this trial. Details related to this clinical trial can be found at www.clinicaltrials.gov (NCT03375047).
  
  
• Completed $47.5M private placement: In May 2019, Translate Bio entered into a securities purchase agreement with several institutional accredited investors for the private placement of 5,582,940 shares of common stock at a purchase price of $8.50 per share, yielding gross proceeds of $47.5 million.

• Presented preclinical data at ASGCT demonstrating successful delivery of lipid-nanoparticle encapsulated mRNA in relevant metabolic disease models: In April 2019 at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting, Translate Bio presented preclinical results that demonstrate the potential of mRNA therapeutics as treatments for urea cycle disorders and organic acidemias using the Company's proprietary liver delivery technology. The presentation summarized findings from experiments in three mouse models of metabolic disorders including ornithine transcarbamylase (OTC) deficiency, argininosuccinate synthetase (ASS1) deficiency (citrullinemia) and methylmalonic acidemia (MMA), which are each caused by a deficiency of a single enzyme specific for each disease.

• Strengthened leadership and board of directors with recent appointments: In April, the Company announced the appointments of Dr. Richard Wooster as chief scientific officer and Pat Sacco as senior vice president of technical operations. The Company also announced the appointments of Dr. Robert Meyer and Dr. Robert Plenge to its board of directors. These appointments strengthen Translate Bio's leadership team and highlight the Company's commitment to innovative mRNA research and development.

Anticipated Milestones

• MRT5005 (CF): Interim data from Phase 1/2 clinical trial in the third quarter of 2019
• MRT5201 (OTC Deficiency): Complete additional preclinical studies and submit data from these studies to the FDA in fourth quarter of 2019
• Identify lead preclinical candidates for additional lung and liver disease targets

Upcoming Events

• Dr. Frank DeRosa, Translate Bio's senior vice president of Research and Development, will give a presentation entitled "Advancing the Delivery of LNP-encapsulated mRNA Therapeutics" in The State of the Art in mRNA Delivery session at the TIDES 2019 Conference on Monday, May 20, 2019 at 10:15 a.m. PT in San Diego, California.

• The Company will give a corporate presentation and host one-on-one meetings at the Jefferies 2019 Global Healthcare Conference taking place June 4-7 at the Grand Hyatt in New York, New York.

First Quarter 2019 Financial Results and Financial Guidance

Translate Bio ended the first quarter of 2019 with $122.6 million in cash, cash equivalents and investments and 45,294,439 shares of common stock outstanding. In May 2019, the Company raised gross proceeds of $47.5 million through a private placement of 5,582,940 shares of its common stock. The Company expects that its existing cash, cash equivalents and investments, together with the proceeds from the private placement, will enable it to fund its operations into the second half of 2020.

Translate Bio reported a net loss of $33.2 million and $21.2 million for the three months ended March 31, 2019 and 2018, respectively.

Collaboration revenue was $1.5 million in the three months ended March 31, 2019 which was derived from the collaboration and license agreement that the Company entered into with Sanofi Pasteur in 2018. There was no collaboration revenue in the three months ended March 31, 2018.

Operating expenses for the three months ended March 31, 2019 were $35.7 million, compared to $22.4 million for the same period in 2018, and were comprised of the following:

• Research and development expenses of $17.4 million during the first quarter of 2019, compared to $12.7 million for the same period in 2018. The increase is primarily due to an increase in costs associated with the continued advancement of the Company's CF program and MRT discovery program.
   
• General and administrative expenses of $6.6 million during the first quarter of 2019, compared to $4.8 million for the same period in 2018. The increase is primarily due to an increase in personnel-related costs.
   
• In the three months ended March 31, 2019 and 2018, the Company recognized non-cash operating expenses of $11.7 million and $4.9 million, respectively, for changes in the fair value of contingent consideration liabilities, related to future potential milestone and earnout payment obligations and, prior to the IPO, anti-dilution rights with respect to common stock issued to Shire. The increase is attributed primarily to the progress of the Company's CF and OTC deficiency programs, the time value of money due to the passage of time, as well as an adjustment in the discount rate.
