– Additional positive data from the Company’s completed Phase 1 clinical trial evaluating ENTR-601-44 reinforces its safety profile and supports the planned Q4 2024 global regulatory filings for a Phase 2 clinical trial –

– Preclinical data presented for the first time, showing exon skipping and dystrophin production for ENTR-601-45, supports the planned Q4 2024 regulatory filings for a global direct-to-patient Phase 2 clinical trial –

BOSTON, Oct. 09, 2024 (GLOBE NEWSWIRE) -- Entrada Therapeutics, Inc. (Nasdaq: TRDA) is a clinical-stage biopharmaceutical company aiming to transform the lives of patients by establishing a new class of medicines that engage intracellular targets long considered inaccessible. Today the Company announced the presentation of clinical and preclinical data in support of its expanding Duchenne clinical franchise at the 29^th Annual Congress of the World Muscle Society in Prague, Czechia from October 8-12, 2024.

“We are excited to present these data which support the advancement of our Duchenne franchise. Adding to our previously reported positive data from our Phase 1 ENTR-601-44-101 trial, we are presenting further safety data demonstrating that there were no adverse findings or clinically relevant changes to any biomarkers of renal toxicity measured at the highest dose tested during the study. We are also pleased to present new data from preclinical studies of ENTR-601-45, showing compelling in vivo dystrophin production and functional improvement,” said Natarajan Sethuraman, PhD, President of R&D at Entrada Therapeutics.

Dr. Sethuraman continued, “We are on track to submit regulatory applications this quarter to initiate separate global Phase 2 clinical trials for ENTR-601-44 and ENTR-601-45 in patients with Duchenne who are exon 44 skipping and exon 45 skipping amenable, respectively. In addition, we plan to submit regulatory applications in 2025 to initiate a global Phase 2 clinical trial for our third Duchenne candidate, ENTR-601-50, in patients who are exon 50 skipping amenable.”

The posters will be presented during Poster Session 2 (DMD Treatments, 5:15-6:15 pm CET) and will be available on the Scientific Presentations page of the Company’s website.

Poster presented by Natarajan Sethuraman, PhD, President of R&D of Entrada Therapeutics: Therapeutic Potential of ENTR-601-44, an Endosomal Escape Vehicle (EEV™)–Oligonucleotide Conjugate for the Treatment of Exon 44 Skip-Amenable Duchenne Muscular Dystrophy

Highlights of the poster presentation include:

• Study ENTR-601-44-101 met all study objectives in healthy male volunteers with no adverse events related to ENTR-601-44 administration.
• Newly presented data include urine PK data, kidney function assessments and additional safety details. The data demonstrate that there were no adverse findings or clinically relevant changes to any biomarkers of renal toxicity at the highest dose tested (6 mg/kg) during the study.
• Dose dependent increases of the final metabolite were observed.
• Statistically significant differences in exon skipping between the 6 mg/kg and placebo administrations were also observed.

These results demonstrate, for the first time, that the EEV platform can safely and effectively deliver oligonucleotide therapeutics to skeletal muscle with significant target engagement in human volunteers.

Poster presented by Sweta Girgenrath, PhD, Vice President, Head of Cardiovascular and Neuromuscular Therapeutic Areas of Entrada Therapeutics: Exon 45 Skipping and Dystrophin Production with ENTR-601-45 in Preclinical Models of Duchenne Muscular Dystrophy

Highlights of the poster presentation include data presented for the first time:

• ENTR-601-45 produced robust dose-dependent exon skipping and dystrophin restoration in both in vitro and in vivo models of exon 45 skip–amenable DMD.
• Improved skeletal muscle function in an exon 45 skip-amenable DMD mouse model suggests that ENTR-601-45 is capable of producing functional dystrophin protein in vivo.
• At the highest dose of ENTR-601-45 examined, dystrophin production and muscle function were similar to healthy control mice.
  

These results show the therapeutic potential of ENTR-601-45 and support further study in patients with DMD amenable to exon 45 skipping.

About Entrada Therapeutics
Entrada Therapeutics is a clinical-stage biopharmaceutical company aiming to transform the lives of patients by establishing a new class of medicines that engage intracellular targets that have long been considered inaccessible. The Company’s Endosomal Escape Vehicle (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 this proprietary, versatile and modular approach, Entrada is advancing a robust development portfolio of RNA-, antibody- and enzyme-based programs for the potential treatment of neuromuscular, ocular, metabolic and immunological diseases, among others. The Company’s lead oligonucleotide programs are in development for the potential treatment of people living with Duchenne who are exon 44, 45 and 50 skipping amenable. Entrada has partnered to develop a clinical-stage program, VX-670, for myotonic dystrophy type 1.
