AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for boys and young men with Duchenne muscular dystrophy who finished an earlier study of ENTR-601-44 or ENTR-601-45 and want to keep taking the study drug.
- Age
- 4 Years to 20 Years
- Sex
- Males only
- Earlier treatment
- Must have completed the earlier study ENTR-601-44-201 or ENTR-601-45-201. Standard Duchenne treatment may continue if health stays stable.
Main reasons for not taking part
- Any change since the earlier study, including safety problems there, that the investigator says makes the study drug unsafe
- A condition or situation that puts the person at high risk of not following the treatment or not finishing the study

A Phase 2, Open-Label Long-Term Extension Study in Participants With Duchenne Muscular Dystrophy Amenable to Exon Skipping to Assess the Long-Term Safety, Tolerability, Pharmacokinetics, and Efficacy of Endosomal Escape Vehicle Phosphorodiamidate Morpholino Oligomer Platform Products (ELEVATE-LTE)
This is a study of investigational medicines ENTR-601-44 and ENTR-601-45 designed to evaluate the long-term safety and tolerability of study drugs in participants with Duchenne muscular dystrophy (DMD).
The investigational medicines are currently being investigated in multiple ascending dose parent studies. After participants complete their respective parent study, there is a need to understand the effects of long-term administration of ENTR-601-44 and ENTR-601-45.
Participants enrolling in this study will begin this long-term extension (LTE) study at the dose level they received upon completion of the parent study with possible dose escalation in the LTE study based on emerging safety and efficacy data from the parent studies.
Participants will:
* Receive study treatment in the form of multiple intravenous (IV) infusions (slow injections) into a vein over the course of several weeks * Visit the clinic regularly for checkups and tests such as: blood and urine tests, physical examinations, questionnaires, and excersice tests. Participants will have a muscle biopsy at the beginning of their participation and after their last dose to allow researchers to compare whether there have been changes in the muscle as a results of the study drug.
Participants are allowed to continue receiving their standard of care therapy for DMD during the study, as long as their health remains stable.
Inclusion: Willing and able to provide consent (if at age of majority) or assent (if a minor); Participant completed clinical study ENTR-601-44-201 or ENTR-601-45-201; Males who are sexually active with a female partner of childbearing potential must agree to use condoms during sexual intercourse.
Exclusion: Any change from the applicable parent study eligibility criteria, including safety events during the parent study, that in the opinion of the investigator in consultation with the medical monitor and/or sponsor designee precludes safe use of study drug; Participant has a condition or circumstance that in the view of the investigator places the subject at high risk of poor treatment compliance or for not completing the study.
