Current report

On June 24, 2024, we announced positive preliminary data from our Phase 1 clinical trial of ENTR-601-44, our most advanced product candidate being developed for patients with DMD. The data announced was based upon data collected as of that date, was aggregated based upon the placebo and study drug groups and did not include urinary biomarkers for the 6 mg/kg cohort. The study has since been completed with no adverse findings noted in the urinary biomarkers for the 6 mg/kg cohort.

Current report

The primary objective of the Phase 1 clinical trial was to evaluate the safety and tolerability of a single dose of ENTR-601-44. The trial also evaluated pharmacokinetics and target engagement, as measured by exon skipping in the skeletal muscle. The trial 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.

Current report

There were no serious adverse events, no drug-related adverse events and no clinically significant changes or trends noted in vital signs, electrocardiograms, 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<0.005) in the 6 mg/kg dose cohort. These results are based upon data collected to date and are aggregated based upon the placebo and study drug groups. Data will be featured in a poster presentation at the 29th Annual Congress of the World Muscle Society, taking place in Prague, Czechia from October 8-12, 2024.

Current report

Based on the positive data from the Phase 1 clinical trial, the Company is on track to submit regulatory applications in the fourth quarter of 2024 to initiate separate global Phase 2 clinical trials for ENTR-601-44 in patients with Duchenne who are exon 44 skipping amenable and for ENTR-601-45 in patients with Duchenne who are exon 45 skipping amenable, subject to regulatory feedback. 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, subject to regulatory feedback.

Current report

General and administrative expenses for the three months ended June 30, 2024 were $9.2 million, compared to $8.2 million for the three months ended June 30, 2023. The increase of $1.0 million was primarily attributable to an increase in personnel costs as the headcount in our general and administrative function increased. Our general and administrative personnel costs are inclusive of stock-based compensation expense of $2.6 million and$1.7 million for the three months ended June 30, 2024 and 2023, respectively.

Current report

Collaboration revenue was $153.8 million for the six months ended June 30, 2024 and $43.4 million for the six months ended June 30, 2024. The $110.4 million increase was primarily driven by the additional research activities completed during the six months ended June 30, 2024, as well as the milestone related to the clinical advancement of VX-670 that was achieved in March of 2024 and added to the transaction price.

Current report

Research and development expenses were $60.6 million for the six months ended June 30, 2024, compared to $49.4 million for the six months ended June 30, 2023. The increase of $11.2 million in research and development expenses was primarily attributable to:

Current report

General and administrative expenses for the six months ended June 30, 2024 were $18.6 million, compared to $16.1 million for the six months ended June 30, 2023. The increase of $2.5 million was primarily attributable to higher personnel costs as our headcount in our general and administrative function increased. Our general and administrative personnel costs for the six months ended June 30, 2024 and 2023 are inclusive of stock-based compensation expense of$4.7 million and$3.2 million, respectively.

Current report

In June 2024, the Company entered into a securities purchase agreement with a limited number of investors relating to a registered direct offering (the “June 2024 Offering”) of 3,367,003 shares of the Company’s common stock at a purchase price of $14.85 per share and, in lieu of common stock to certain investors who so chose, pre-funded warrants (the “Pre-Funded Warrants”) to purchase 3,367,003 shares of Common Stock at a purchase price of $14.8499 per Pre-Funded Warrant, which represents the price per share at which the shares of common stock were sold to the investors in the June 2024 Offering, minus $0.0001, which is the exercise price of each Pre-Funded Warrant. The June 2024 Offering was made pursuant to the shelf registration statement on Form S-3 (File No. 333-268099) previously filed by the Company with the Securities and Exchange Commission (the “SEC”) on November 1, 2022 and declared effective by the SEC on November 7, 2022. The aggregate net proceeds from the sale of common stock and Pre-Funded Warrants in the June 2024 Offering were approximately $99.6 million, after deducting offering expenses payable by the Company. The Company will receive nominal proceeds, if any, from the exercise of the Pre-Funded Warrants.

Reworded paragraphs (28)

Previous wording

We are initially focused on the development of EEV therapeutics for rare neuromuscular diseases, starting with Duchenne muscular dystrophy ("Duchenne" or "DMD"). DMD is caused by genetic mutations that prevent the creation of functional dystrophin, a protein required to maintain the structural integrity of muscle cells. In our neuromuscular disease programs, we link EEVs to small strands of nucleic acids called oligonucleotides, including phosphorodiamidate morpholino oligomers ("PMOs"). We are developing EEV-PMOs that promote the skipping of these mutations associated with DMD. We believe that our EEV-PMO exon-skipping therapy will enable the production of functional dystrophin to slow, stop or even reverse disease progression. Our most advanced therapeutic candidate, ENTR-601-44, is being developed for patients with DMD that are exon 44 skipping amenable. On July 24, 2023, Entrada received authorization from the United Kingdom Medicines and Healthcare Products Regulatory Agency ("MHRA") and Research Ethics Committee ("REC") for its Clinical Trial of an Investigational Medicinal Product ("CTIMP") for its Phase 1 clinical trial in healthy volunteers, ENTR-601-44-101. On March 13, 2024, we announced that the first, second and third cohorts of participants had been successfully dosed. We have since initiated dosing of the fourth and final cohort, and expect to report data from the Phase 1 clinical trial in October of 2024. On December 19, 2022, we announced that we received a clinical hold notice from the U.S. Food and Drug Administration ("FDA") regarding the Investigational New Drug application ("IND") for ENTR-601-44. The FDA has requested that we continue to gather and submit additional information regarding ENTR-601-44 and we are actively working to resolve the clinical hold in the United States.
