A Study to Investigate the Safety and Efficacy of RO7204239 in Combination With Risdiplam (RO7034067) in Ambulatory Children With Spinal Muscular Atrophy

key information

study id #: NCT05115110

condition: Spinal Muscular Atrophy (SMA)

status: Recruiting


Risdiplam works by helping the body produce more survival motor neuron (SMN) protein throughout the body. This means fewer motor neurons – nerve cells that pass impulses from nerves to muscles to cause movement – are lost, which may improve how well muscles work in people with SMA. RO7204239 is an investigational anti-myostatin antibody that is designed to target myostatin. Myostatin plays an important role in the regulation of skeletal muscle size by controlling growth. Inhibiting myostatin may help muscles grow in size and strength. RO7204239 in combination with risdiplam, which is designed to increase the amount of SMN protein throughout the body, has the potential to further improve motor function and clinical outcomes for people living with SMA.

This trial will study the safety and efficacy of RO7204239 in combination with risdiplam in children aged 2-10 years with spinal muscular atrophy (SMA) that are ambulant.
