BOSTON, May 10, 2023 (GLOBE NEWSWIRE) -- Entrada Therapeutics, Inc. (NASDAQ:TRDA), a biopharmaceutical company aiming to transform the lives of patients by establishing intracellular Endosomal Escape Vehicle (EEV™)-therapeutics as a new class of medicines, today reported financial results for the first quarter ending March 31, 2023, and highlighted recent business updates.

"In the first quarter, we successfully closed on our transformational collaboration with Vertex for the development of EEV-therapeutics targeting myotonic dystrophy type 1, the most prevalent form of muscular dystrophy. In addition to advancing this important program, the collaboration provides validation of our proprietary EEV platform and extends our cash runway into the second half of 2025," said Dipal Doshi, President and Chief Executive Officer of Entrada Therapeutics. "Within our growing Duchenne franchise, we are pursuing global opportunities to initiate a healthy volunteer clinical trial for our ENTR-601-44 program while simultaneously working to address FDA's feedback regarding our IND. There is a profound unmet medical need for Duchenne patients who are exon 44 skipping amenable and we remain very confident in achieving our goal of initiating a clinical trial in 2023."

Recent Corporate Highlights

• Entrada is actively working to resolve the clinical hold on its Investigational New Drug (IND) application for ENTR-601-44 with the U.S. Food and Drug Administration (FDA). Given the extraordinary unmet medical need, the Company is simultaneously pursuing global opportunities with the continued goal of initiating a healthy volunteer trial in 2023.

• In February 2023, Entrada announced the closing of its strategic collaboration and license agreement with Vertex for the discovery and development of intracellular EEV-therapeutic candidates for myotonic dystrophy type 1 (DM1). Under the terms of the agreement, Entrada received an upfront payment of $224 million, as well as an equity investment of $26 million in February 2023. Entrada is eligible to receive up to $485 million for the successful achievement of certain research, development, regulatory and commercial milestones, and tiered royalties on future net sales for any products that may result from the collaboration agreement.

• In March 2023, Entrada presented additional preclinical data at the Muscular Dystrophy Association (MDA) Clinical & Scientific Conference supporting the development of ENTR-601-45 for the potential treatment of patients with Duchenne who are exon 45 skipping amenable, including data visualizing dystrophin restoration in skeletal and cardiac muscle cells. Entrada selected ENTR-601-45 as the second clinical candidate within its Duchenne franchise in January 2023 and plans to submit an IND application in the fourth quarter of 2024.

• In April 2023, Entrada announced the appointment of Dr. Bernhardt "Bernie" Zeiher to its Board of Directors. Dr. Zeiher has over 25 years of experience in the pharmaceutical industry and has supported the development and approval of 15 products across multiple therapeutic areas. Dr. Zeiher served most recently as the Chief Medical Officer at Astellas Pharma.

First Quarter 2023 Financial Results

Cash Position: Cash, cash equivalents and marketable securities were $411.6 million as of March 31, 2023, compared to $188.7 million as of December 31, 2022. This increase is primarily due to the $250.0 million in proceeds from the Vertex Agreement. Entrada anticipates that its cash, cash equivalents and marketable securities as of March 31, 2023, together with ongoing research support and the anticipated achievement of certain milestones under the Vertex Agreement, will be sufficient to extend its cash runway into the second half of 2025, supporting the Company's expansion and continued development of EEV-therapeutic candidates targeting Duchenne as well as other indications beyond neuromuscular diseases.

Collaboration Revenue: Collaboration revenue was $25.3 million for the first quarter of 2023 following the closing of the Vertex Agreement in February 2023. There was no collaboration revenue in the first quarter of 2022.

Research & Development (R&D) Expenses: R&D expenses were $23.1 million for the first quarter of 2023, compared to $15.7 million for the same period in 2022. This increase was primarily due to additional investment in preclinical studies to support future clinical trials, sublicense fees, and higher personnel costs (including non-cash, stock-based compensation).

General & Administrative (G&A) Expenses: G&A expenses were $7.9 million for the first quarter of 2023, compared to $6.4 million for the same period in 2022. This increase was primarily due to higher personnel costs (including non-cash, stock-based compensation), legal costs and other costs to support continued research and development activities.

Net Loss: Net loss was $6.7 million for the first quarter of 2023, compared to a net loss of $21.7 million for the same period in 2022.
