Estudio de ARO-DUX4 en pacientes adultos con distrofia muscular facioescapulohumeral tipo 1

1 de octubre de 2026 actualizado por: Sarepta Therapeutics, Inc.

Un estudio de fase 1/2a de aumento de dosis para evaluar la seguridad, tolerabilidad, farmacocinética y farmacodinamia de ARO-DUX4 en pacientes adultos con distrofia muscular facioescapulohumeral tipo 1

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics of SRP-1001 in participants with facioscapulohumeral muscular dystrophy Type 1 (FSHD1). In Part 1 of the study, participants will receive one dose of SRP-1001 or placebo. In Part 2 of the study, participants will receive 4 doses of SRP-1001 or placebo. Participants who complete Part 1 will have the option to re-screen and re-randomize into Part 2. All participants will undergo pre- and post-dose magnetic imaging resonance (MRI)-guided muscle biopsies (a total of 2 biopsies). Participants who complete Part 1 and enroll in Part 2 will be required to undergo an additional screening biopsy. Participants completing Part 1 or Part 2 may have the option to continue to receive drug in an open-label extension study or may be eligible to participate in later-stage clinical studies.
