About this study
This was a research study to learn more about a drug to treat spinal muscular atrophy (SMA). SMA is a genetic disease that causes you to lose muscle control. There is no cure.
The drug is called nusinersen. It is also known as Spinraza. The U.S. Food and Drug Administration (FDA) has approved nusinersen as a treatment for SMA.
In this study, we wanted to find the best and safest dose of nusinersen to improve muscle function. We injected the drug into a participant's lower back using a thin needle. This procedure is called a lumbar puncture.
Eligibility overview
