Sikkerhet, tolerabilitet, farmakodynamisk, effekt og farmakokinetisk studie av DYNE-101 hos deltakere med myotonisk dystrofi type 1 (ACHIEVE)
En randomisert, placebokontrollert studie med flere stigende doser som vurderer sikkerhet, tolerabilitet, farmakodynamikk, effekt og farmakokinetikk til DYNE-101 administrert til deltakere med myotonisk dystrofi type 1
The primary purpose of the study is to evaluate the safety and tolerability of multiple intravenous (IV) doses of DYNE-101 administered to participants with Myotonic Dystrophy Type 1 (DM1).
The study consists of 4 periods: A Screening Period (up to 8 weeks), a Placebo-Controlled Period (24 weeks), a Treatment Period (24 weeks) and a Long-Term Extension (LTE) Period (208 weeks) in both multiple-ascending dose (MAD) and dose expansion cohorts.

Exclusion Criteria:
- History of major surgical procedure within 12 weeks prior to the start of investigative product administration or an expectation of a major surgical procedure (eg, implantation of cardiac defibrillator) during the study.
- History of anaphylaxis.
- Medical condition other than DM1 that would significantly impact ambulation or participation in functional assessments.
- Treatment with medications that can improve myotonia within a period of 5 half-lives of the medication prior to performing screening assessments.
- Electrocardiogram (ECG) with the corrected QT interval by Fridericia's Formula (QTcF) ≥450 milliseconds (ms) in men and QTcF ≥460 ms in women, PR ≥240 ms, left bundle-branch block, or a conduction defect, which is clinically significant in the opinion of the Investigator.
- Percent predicted forced vital capacity (FVC) <50%.
- History of tibialis anterior biopsy within 3 months of Day 1 or planning to undergo tibialis anterior biopsies during study period for reasons unrelated to the study.
- Participant has a history of suicide attempt, suicidal behavior, or has any suicidal ideation within 6 months prior to Screening that meets criteria at a level of 4 or 5 of the Columbia Suicide Severity Rating Scale (C-SSRS) or who, in the opinion of the Investigator, is at significant risk to commit suicide.
- Use of glucagon-like peptide 1 (GLP-1) agonist medications including semaglutide, dulaglutide, liraglutide, exenatide, or tirzepatide within a period of 5 half-lives of the medication prior to performing screening assessments.
