Zolgensma Trials and Their Results

Intravenous Zolgensma has been tested in human clinical trials, with children up to the age of 2 years, since 2014. It has been consistently shown to have a well-understood safety profile and to be well-tolerated in these trials.

In many children who have SMA, when compared to no treatment, zolgensma has been shown to increase the availability of SMN protein, leading to clinically meaningful improvements in muscle function.
