Emerging Growth Company and Smaller Reporting Company Status
Current report
We are also a “smaller reporting company” because the market value of our stock held by non-affiliates was less than $250 million as of June 30, 2025. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

Reworded paragraphs (38)
Previous wording
We are a clinical-stage biopharmaceutical company aiming to transform the lives of patients by establishing a new class of medicines which engage intracellular targets that have long been considered inaccessible. Our 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. Our lead oligonucleotide programs are in development for the potential treatment of people living with Duchenne muscular dystrophy (DMD) who are exon 44, 45, 50 and 51 skipping amenable. We currently have two product candidates, ENTR-601-44 and ENTR-601-45, in clinical development and expect to file for regulatory clearance for a third, ENTR-601-50, in the fourth quarter of 2025. We reported positive preliminary data in healthy volunteers from a Phase 1 clinical trial of ENTR-601-44 in 2024 and anticipate reporting data from the global Phase 1/2 multiple ascending dose (MAD) portion of the study in the first half of 2026. We have also partnered with Vertex to develop a clinical-stage program, VX-670, for myotonic dystrophy type 1. As of June 30, 2025, we had cash, cash equivalents and marketable securities of $354.0 million. Based on our current operating plans, we believe that our cash, cash equivalents and marketable securities as of June 30, 2025 will be sufficient to fund our operations into the second quarter of 2027.
Current wording
We are 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. Our 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. Leveraging this proprietary, versatile and modular approach, we are advancing a robust development portfolio of RNA- and protein-based programs for the potential treatment of neuromuscular and ocular diseases, among others. Our lead oligonucleotide programs are in development for the potential treatment of people living with Duchenne muscular dystrophy (DMD) who are exon 44, 45, 50 and 51 skipping amenable. We currently have two product candidates, ENTR-601-44 and ENTR-601-45, in clinical development and have filed for UK regulatory clearance for a third, ENTR-601-50, in the third quarter of 2025. We expect to file for EU regulatory clearance in the second half of 2026 and initiate the study by the end of 2026. We expect to submit for regulatory clearance for a fourth product candidate, ENTR-601-51 in 2026. We reported positive preliminary data in healthy volunteers from a Phase 1 clinical trial of ENTR-601-44 in 2024, have fully enrolled the first cohort of patients in the global Phase 1/2 multiple ascending dose (MAD) portion of the study and anticipate reporting data in the second quarter of 2026. We have dosed the first patient in our Phase 1/2 clinical trial for ENTR-601-45, and we anticipate data from the first patient cohort in mid-2026. We have also partnered with Vertex Pharmaceuticals Incorporated (“Vertex”) to develop a clinical-stage program, VX-670, for myotonic dystrophy type 1. As of September 30, 2025, we had cash, cash equivalents and marketable securities of $326.8 million. Based on our current operating plans, we believe that our cash, cash equivalents and marketable securities as of September 30, 2025 will be sufficient to fund our operations into the third quarter of 2027.
Previous wording
During the second quarter of 2025, we continued to progress our portfolio and achieved the important milestone of first patient dosed in ELEVATE-44-201. We anticipate data from the first patient cohort of the multi-ascending dose trial in the first half of 2026. We also initiated ELEVATE-45-201 and remain on track to dose the first patient in the third quarter of 2025. We anticipate data from the first patient cohort in mid-2026. Operationally, we strengthened the team in key areas including clinical development and medical affairs, as we continue to activate multiple clinical trial sites in the U.K. and EU for both ELEVATE-44-201 and ELEVATE-45-201. By year end, we expect to have three clinical-stage programs in our DMD franchise (ENTR-601-44, ENTR-601-45, ENTR-601-50), complementing the ongoing progress of our VX-670 partnership with Vertex Pharmaceuticals Incorporated (“Vertex”). This clinical development progress builds upon positive preliminary data in healthy volunteers from a Phase 1 clinical trial, ENTR-601-44-101, as first reported in 2024.
