BOSTON, June 24, 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. The Company today announced positive preliminary data from its Phase 1 clinical trial, ENTR-601-44-101. Data will be featured in a presentation at the 29th Annual Congress of the World Muscle Society, taking place in Prague, Czechia from October 8-12, 2024.
“We are excited to present the first clinical data from our Duchenne franchise, led by ENTR-601-44. ENTR-601-44 was well tolerated in healthy volunteers and we are pleased to see significant plasma concentration, muscle concentration and exon skipping. We achieved the goals of the ENTR-601-44-101 trial, including the identification of a clinically relevant starting dose for the planned Phase 2 global patient study. Based on the cumulative data to date, we expect to see a significant accumulation of exon skipping and dystrophin production in patients, which we believe will lead to an improvement in functional outcomes after multiple doses,” said Dipal Doshi, Chief Executive Officer at Entrada Therapeutics.
He continued, “Patients are at the core of our mission at Entrada. We believe that the flexibility of our EEV-based approach will allow the therapeutic to be tailored to meet the changing needs of growing pediatric and young adult patients via dosing and other important parameters. Today’s update represents a clear validation and differentiation of Entrada’s approach and brings us one step closer to providing a potential treatment for this relentlessly progressive neuromuscular disease.”
The primary objective of Entrada’s Phase 1 clinical trial was to evaluate the safety and tolerability of a single dose of ENTR-601-44. ENTR-601-44-101 also evaluated pharmacokinetics and target engagement, as measured by exon skipping in the skeletal muscle. The study included a total of 32 healthy male volunteers across four cohorts, with each cohort consisting of six participants receiving ENTR-601-44 and two participants receiving a placebo control. The doses administered across the cohorts were 0.75 mg/kg, 1.5 mg/kg, 3 mg/kg and 6 mg/kg.
There were no serious adverse events, no drug-related adverse events and no clinically significant changes or trends noted in vital signs, ECGs, physical exams or laboratory assessments observed in the trial. The study demonstrated target engagement as measured by exon skipping on a ng/g of tissue adjusted basis supporting the importance of endosomal escape to therapeutic index optimization. Muscle concentration was detected in all six subjects in the 6 mg/kg dose cohort (mean of 53.8 ng/g, range 40 ng/g-73.5 ng/g) and mean target engagement as measured by exon skipping was 0.44% (range 0.3-0.65%). Exon skipping was statistically significant compared to the placebo control (p
