Entrada Therapeutics Receives Authorization in the United Kingdom to Initiate Phase 1 Clinical Trial of ENTR-601-44 for the Potential Treatment of Duchenne Muscular Dystrophy

– First participant is expected to be dosed in September 2023 with data anticipated in the second half of 2024 –

– Cash runway extended through the end of 2025 –

BOSTON, Aug. 01, 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 announced that it has received authorization from the United Kingdom Medicines and Healthcare Products Regulatory Agency (MHRA) and Research Ethics Committee (REC) for its CTIMP (Clinical Trial of an Investigational Medicinal Product) for a Phase 1 clinical trial in healthy volunteers for ENTR-601-44. ENTR-601-44 is Entrada’s lead product candidate within its Duchenne franchise and is being developed for the potential treatment of individuals with Duchenne who are exon 44 skipping amenable.

“We are looking forward to this important next step in advancing ENTR-601-44 for the potential treatment of people with exon 44 skipping amenable Duchenne muscular dystrophy, where there exists a profound unmet medical need,” said Dipal Doshi, President and Chief Executive Officer of Entrada Therapeutics. “This milestone, coupled with the extension of our cash runway through the end of 2025, positions Entrada to advance our Duchenne franchise while broadening the potential of our intracellular therapeutics across serious diseases.”

The Phase 1 trial’s primary objective is to evaluate the safety of a single dose of ENTR-601-44 in healthy volunteers, with a target enrollment of approximately 40 participants. The trial will also evaluate tolerability, pharmacokinetics and target engagement as measured by exon skipping in the skeletal muscle. The first participant is expected to be dosed in September of this year with data anticipated in the second half of 2024.

About ENTR-601-44

ENTR-601-44, a proprietary Endosomal Escape Vehicle (EEV™)-conjugated phosphorodiamidate morpholino oligomer (PMO), is the lead product candidate within its Duchenne franchise from Entrada’s growing pipeline of EEV-therapeutics. Each EEV-PMO therapeutic candidate has an oligonucleotide sequence designed and optimized for the specific subpopulation of interest. ENTR-601-44 is designed to address the underlying cause of Duchenne muscular dystrophy due to mutated or missing exons in the DMD gene. ENTR-601-44, an investigational therapy for the potential treatment of people living with Duchenne who are exon 44 skipping amenable, has the potential to restore the mRNA reading frame and allow for the translation of dystrophin protein that is slightly shortened but still functional.

About Duchenne Muscular Dystrophy

Duchenne muscular dystrophy is a rare genetic disease that causes progressive muscle degeneration and weakness throughout the body. Duchenne is caused by mutations in the DMD gene, which leads to inadequate production of dystrophin, a protein essential to maintaining the structural integrity and function of muscle cells. Duchenne causes progressive loss of muscle function throughout the body, which limits mobility and causes heart and respiratory complications in the later stages of the disease. Currently approved therapies for Duchenne seek to improve dystrophin production, but to date, the clinical benefits of these products have not been confirmed.

About Entrada Therapeutics

Entrada Therapeutics is a biopharmaceutical company aiming to transform the lives of patients by establishing a new class of medicines, Endosomal Escape Vehicle (EEV™)-therapeutics, to engage intracellular targets that have long been considered inaccessible and undruggable. The Company’s EEV therapeutics are designed to enable the efficient intracellular delivery of a wide range of therapeutics into a variety of organs and tissues, resulting in an improved therapeutic index. Through its proprietary, highly versatile and modular EEV platform, Entrada is building a robust development portfolio of RNA-, antibody- and enzyme-based programs for the potential treatment of neuromuscular, immunological, ocular and metabolic diseases, among others. The Company’s lead oligonucleotide programs include ENTR-601-44 and ENTR-601-45 for the potential treatment of people living with Duchenne who are exon 44 and 45 skipping amenable, respectively, as well as our partnered candidate ENTR-701 targeting myotonic dystrophy type 1 (DM1).
