Assessing Pediatric Endpoints in DM1 (ASPIRE-DM1)

Pediatrics Pediatric Subjects

The overall goal of the study is to establish valid clinical endpoint assessments for children with congenital myotonic dystrophy type 1 and childhood myotonic dystrophy type 1, and develop biomarkers for the condition.

Pediatrics Adult Subjects

The purpose of this study is to evaluate the safety and tolerability of a single intravenous infusion of AB-1003 in adults diagnosed with limb girdle muscular dystrophy type 2I/R9 (LGMD2I/R9). Participants will be treated in sequential, dose-level cohorts. (Part 1)

ARST2032: A Prospective Phase 3 Study of Patients with Newly Diagnosed Very Low-Risk and Low-Risk Fusion Negative Rhabdomyosarcoma

Cancer Pediatrics Sarcoma Pediatric Subjects Adult Subjects

Rhabdomyosarcoma is a type of cancer that occurs in the soft tissues in the body. This phase III trial aims to maintain excellent outcomes in patients with very low risk rhabdomyosarcoma (VLR-RMS) while decreasing the burden of therapy using treatment with 24 weeks of vincristine and dactinomycin (VA) and examines the use of centralized molecular risk stratification in the treatment of rhabdomyosarcoma. Another aim of the study it to find out how well patients with low risk rhabdomyosarcoma (LR-RMS) respond to standard chemotherapy when patients with VLR-RMS and patients who have rhabdomyosarcoma with DNA mutations get separate treatment. Finally, this study examines the effect of therapy intensification in patients who have RMS cancer with DNA mutations to see if their outcomes can be improved.
