BOSTON, Nov. 07, 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 third quarter ending September 30, 2023, and highlighted recent business updates.

“The third quarter marked an important milestone for Entrada, as we transitioned into a clinical-stage company, with the initiation of the Phase 1 clinical trial in healthy volunteers for our lead Duchenne product candidate, ENTR-601-44. Duchenne muscular dystrophy is a relentlessly progressive neurodegenerative disease, and we are committed to bringing forward potential new therapeutic options for people living with Duchenne who have mutations that are amenable to particular exon skipping therapies,” said Dipal Doshi, President and Chief Executive Officer of Entrada Therapeutics. “We are well-positioned to embark upon our next phase of growth, as we further advance our Duchenne franchise and progress indications beyond neuromuscular diseases.”

Recent Corporate Highlights

• In September 2023, Entrada dosed the first participant in its Phase 1 clinical trial evaluating ENTR-601-44 for the potential treatment of individuals with Duchenne muscular dystrophy (DMD) who are exon 44 skipping amenable. The primary objective of Entrada’s Phase 1 clinical trial, which is being conducted in the United Kingdom, is to evaluate the safety and tolerability of a single dose of ENTR-601-44 in healthy male volunteers, with a target enrollment of approximately 40 participants. The trial will also evaluate pharmacokinetics and target engagement, as measured by exon skipping in skeletal muscle. Entrada expects to report data from the Phase 1 clinical trial in the second half of 2024.
  
  The Company will provide an update on the clinical hold on its Investigational New Drug (IND) application for ENTR-601-44 with the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2023.

• Entrada announced the selection of a third clinical candidate within its Duchenne franchise, ENTR-601-50, for the potential treatment of people living with Duchenne who are exon 50 skipping amenable. The selection of ENTR-601-50 is based on in vivo preclinical data demonstrating robust exon 50 skipping and dystrophin production across cardiac and skeletal muscle groups. Entrada expects to present these preclinical data in the first half of 2024 and plans to submit a Clinical Trial Application (CTA)/IND submission to initiate clinical development for ENTR-601-50 in 2025.

• In October 2023, the Company achieved a milestone pursuant to the Vertex Agreement related to preclinical IND-enabling GLP toxicology studies of ENTR-701 that triggered a $17.5 million milestone payment, which the Company expects to receive in the fourth quarter of 2023.

• In July 2023, Entrada entered into a license agreement to advance the development of ENTR-501 with Pierrepont Therapeutics, Inc., a mitochondrial disease-focused company. ENTR-501 is an intracellular thymidine phosphorylase enzyme replacement therapy in development for the treatment of mitochondrial neurogastrointestinal encephalomyopathy (MNGIE). MNGIE is a slowly progressive and fatal, ultra rare disease for which there are no treatment options available.

Third Quarter 2023 Financial Results

Cash Position: Cash, cash equivalents and marketable securities were $353.6 million as of September 30, 2023, compared to $188.7 million as of December 31, 2022. Entrada anticipates that its cash, cash equivalents and marketable securities as of September 30, 2023, together with Vertex collaboration ongoing research support and the anticipated achievement of certain milestones, will be sufficient to fund the Company's operating expenses and capital expenditure requirements through 2025.

Collaboration Revenue: Collaboration revenue was $43.7 million for the third quarter of 2023. There was no collaboration revenue in the third quarter of 2022.

Research & Development (R&D) Expenses: R&D expenses were $22.2 million for the third quarter of 2023, compared to $19.0 million for the same period in 2022. This increase was primarily due to the initiation of the ENTR-601-44 Phase 1 clinical trial, additional investment in IND-enabling studies to support future clinical trials and higher personnel costs, including non-cash, stock-based compensation.

General & Administrative (G&A) Expenses: G&A expenses were $7.5 million for the third quarter of 2023, compared to $7.0 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 its ongoing clinical trial and continued research and development activities.

Net Income (Loss): Net income was $35.5 million for the third quarter of 2023, compared to a net loss of $(25.1) million for the same period in 2022.
