MELPIDA for SPG50

This study is testing a gene therapy called MELPIDA for people with SPG50 (Spastic Paraplegia Type 50), a rare genetic disorder. MELPIDA aims to deliver a working copy of the AP4M1 gene to brain cells to help with the disease. The main goal is to see how safe MELPIDA is by tracking any side effects over 60 months. The study is looking for 4 participants, aged 4 months to 10 years, who have a confirmed diagnosis of SPG50 with specific genetic changes in the AP4M1 gene and signs of neurological problems. This trial will also explore how well MELPIDA might improve disease symptoms.

  • Incidence of unanticipated treatment-related toxicities, Grade 3 or higher in participants with SPG5060 months

    Incidence of unanticipated treatment-related toxicities, Grade 3 or higher, in participants with SPG50 will be determined from the collection of occurrence and severity of serious adverse events (SAEs). Adverse events will be determined according to Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0.
