Melpida: Recombinant Adeno-associated Virus (serotype 9) Encoding a Codon Optimized Human AP4M1 Transgene (hAP4M1opt)

MELPIDA is proposed for the treatment of subjects with SPG50 and targets neuronal cells to deliver a fully functional human AP4M1 cDNA copy via intrathecal injection to counter the associated neuronal loss. Outcomes will evaluate the safety and tolerability of a single dose of MELPIDA, which will be measured by the treatment-associated adverse events (AEs) and serious adverse events (SAEs). Secondarily, the trial will explore efficacy in terms of disease burden assessments.

A Study of CAP-1002 in Ambulatory and Non-Ambulatory Patients With Duchenne Muscular Dystrophy (HOPE-3)

HOPE-3 is a two cohort, Phase 3, multi-center, randomized, double-blind, placebo-controlled clinical trial evaluating the efficacy and safety of a cell therapy called CAP-1002 in study participants with Duchenne muscular dystrophy (DMD) and impaired skeletal muscle function. Non-ambulatory and ambulatory boys and young men who meet eligibility criteria will be randomly assigned to receive either CAP-1002 or placebo every 3 months for a total of 4 doses during the first 12-months of the study. All participants will be eligible to receive 4 doses of CAP-1002 for an additional 12 months as part of an open-label extended assessment period.

Motor Outcomes to Validate Evaluations in FSHD (MOVE FSHD) (MOVE FSHD)

The primary goal of this proposal is to collect motor and functional outcomes specific to FSHD over time. By collecting measures specific to FSHD, this will help ensure the best level of clinical care is being provided. Also, the hope is to speed up drug development by gaining a better understanding of how having FSHD impacts motor function and other health outcomes (i.e. breathing, wheelchair use, etc.) and how big a change in motor function would be clinically meaningful to those with FSHD. Motor Outcomes to Validate Evaluations in FSHD (MOVE FSHD) will have approximately 450 FSHD participants followed for a minimum of 3 years. A subset of MOVE FSHD participants, approximately 200, will participate in the MOVE+ sub-study which includes whole body MRI and muscle biopsy.
